Atomic Absroption Spectroscopy essays

Atomic Absroption Spectroscopy essays Atomic Absorption Spectrophotometers An atomic absorption spectrophotometer consists of many complex and integral pieces. These components work together to help determine the concentrations of many different elements in various products to a very precise and accurate value. The instrumentation can vary depending on the use the machine is designed for, and the amount of accuracy that is required. There are four basic components of atomic absorption spectrophotometer. They are as follows: a narrow band source of EMR (electromagnetic radiation), the sample compartment where the sample is atomized, a monochromator which is used to isolate the certain wavelength of EMR you are interested in, and a detector which determines how much of the EMR was absorbed scattered by the sample. The most common source used in atomic absorption spectroscopy (AAS) is a hollow cathode lamp (HCL). The HCL has two electrodes, an anode that is negatively charged, and a cathode having positive charge. This charge is a result of a large electrical potential across the electrodes. These electrodes are contained in a sealed glass tube filled with an inert gas such as argon or neon. This inert gas is to prevent the oxidization of the electrodes. The anode is made of tungsten and the cylindrical cathode is made of the element of interest. This results in that a different lamp is required for each element t hat is to be analysis, but it is possible to buy lamps which have cathodes made of multiple materials making it possible to analyze more than one element at a time. The EMR that is created from the lamp is focused on the sample compartment in a fine beam. In the sample compartment the sample is atomized, by either flame atomization or by electro thermal atomization. In the flame atomization the sample is introduced into laminar flow burner where the sample is mixed with the fuel and oxidant and introduced into the flame as a smooth (laminar) flow. The mixture t...

ESL Curriculum Planning for Teaching English

ESL Curriculum Planning for Teaching English This curriculum plan for non-trained teachers of ESL/EFL focuses on building a program for your class or private students. The first part focuses on the basics of ESL. There are a few important aspects to always keep in mind while developing any curriculum, be it only a few lessons or a full course: Language skills need to be recycled many times before they are actively acquired.All language skills (reading, writing, speaking, and listening) should be involved in the learning process.Understanding grammar rules does not necessarily mean that a student can use that grammar, as students need to actively practice skills they are learning. Language Recycling An acquired language needs to be repeated in a various number of guises before it can be actively used by the student. Studies have shown that new linguistic functions need to be repeated at least six times before most learners can consider the new piece of language theirs. After six repetitions, the newly-acquired language skills are usually still only passively activated. The learner will require more repetitions before he or she will be able to use the skills actively in everyday conversation. Here is an example of language recycling using the present simple: Work on the present simple rules.Read an article about the daily routines of someone.Listen to someone who describes his or her daily tasks.Have a discussion asking him or her to describe what he or she does on a daily basis. Use All Four Skills Employing all four linguistic skills (reading, writing, listening, and speaking) when working through a lesson will help you recycle language during the lesson. Learning rules are important, but, in my opinion, practicing the language is even more important. Bringing all these aspects into a lesson will add variety to the lesson and help the learner pragmatically practice the language. Ive met many learners who can knock off a grammar sheet without a mistake and then  when asked, Could you describe your sister? they have problems. This is generally due to the emphasis in many school systems for learning grammar. Putting It All Together So, now you understand the basic tenets of teaching English effectively. You might be asking yourself the question what do I teach? When planning a course, most coursebooks build their curriculum around certain themes that help glue everything together. While this can be rather complicated, I would like to provide a simple example that develops the present simple and past simple. Use this type of outline to build your lesson and remember to provide a number of elements, including listening, reading, writing, and speaking. You will find that your lessons have a  purpose and specific objectives which are clearly definable, like helping you and your learners recognize the progress you are making. Who are you? What do you do? (Daily routines)A present simple example: What do you do? I work at Smiths. I get up at seven, etc.To be present example: Im married. Shes thirty-four.Descriptive adjectives example: I am tall. He is short.Tell me about your past. Where did you go on your last holiday?A past simple example: Where did you go on holiday when you were a child?To be past example: The weather was fantastic.Irregular verbs example: Go - went; Shine - shone Finally, the lesson generally will be divided into three principal sections. Introduction:  Introducing or reviewing grammar or function.Development: Taking that grammar and working on it in reading, listening, and other forms. This section should make up the bulk of your lesson and include a number of different activities, if possible.​Review: Review the principle concepts covered during the lesson. This can be very straightforward and either student or teacher-led, depending on the level of your learners.

Management Accounting- A case study in balanced scorecard Essay

Management Accounting- A case study in balanced scorecard - Essay Example The balanced scorecard revolves around this strategy. In relation to growing the revenues, the shift of emphasis on traditional ticketing distribution will enable the company to cut on various items on its administrative overhead. This entails a shift in market strategy, mainly by re-positioning the Yunnan Lucky Air brand to becoming an on-line travel leader through its e-commerce business model. These changes are reflected on the perceptions as objectives about the brand and the website on the customers perspective, and would later transform into expectations of customers. In order to meet these expectations, various internal processes in line with the adoption of the e-commerce business model in terms of sales and distribution should be addressed. Lastly, learning and growth objectives are related to the changes in the companys HR policies because of the new organisational structure. Fulfiling these objectives tell about how the strategies will be carried out as soon as changes are enacted. The balanced scorecard has been widely accepted by the business community since its introduction by Norton and Kaplan in 1992 (Kaplan & Norton 1993). This paper aims to explore the benefits as well as the limitations of the framework in order to recommend the adoption of it to the business practices of the Chinese airline company, Yunnan Lucky Air. One major benefit of the balanced scorecard is that the framework provides a multidimensional assessment of the issues in line with a companys vision and strategy using the four perspectives (Dror 2008). In the case of Yunnan Lucky Air, for instance, setting an expansion strategy can be off-the-target if the objectives in line with the strategy are not coordinated by these four objectives. If the company chooses to expand with only regard to the customers and not its shareholders, an expansion strategy of continuing the low-cost positioning

How did women's fashions change in the 1920's Have these styles Research Paper

How did women's fashions change in the 1920's Have these styles survived or ever been revivied How do they reflect the new fre - Research Paper Example The designs, colours and fabrics and the associated accessories used by fashion technologists are not to be seen merely as expressions of random ideas or creativity. They, in fact, are meant to make statements; statements of joy, liberation, individuality, functionality, self-expression and post-war optimism. The fashion trends of the hedonistic 1920s assume importance in this light and the most wonderful thing about those well-coordinated outfits was the enormous freedom they gave women ‘to choose’. Women are the loveliest creation of god and now they were to become even lovelier. The music of 1920s was a trendsetter and so were the new fashion modules of the period, their ‘classical’ nature notwithstanding. They were simple, yet elegant carrying with them timeless and age-defying sex-appeal. Any discussion on women’s fashion in the colorful 1920s has to be centered on close-fitting cloche hats without rims, sleeveless dresses, slipper shoes, sheer s tockings, Madeleine Vionnet’s very feminine bias-cuts, pantsuits, canes, body-flattering Coco Chanel silhouettes and Art Deco fashion with its integration of the Oriental culture, not to mention La Garconne style, handbags, jewellery and such things so much so that any attempt to visualize their appeal by taking a look at black-and-white snapshots of that period does not just work. 1920s, more commonly known the ‘roaring 20s’, as much as 1940s, both being points of time that have witnessed not only the horror of World Wars but also the serenity that the end of hostilities marked, were historically prone to see a sea change in terms of people’s attitude and women’s in particular in terms of the idea of fashion. The first short skirt sounded the death knell of the haute couture era [Skirt length reached its lowest point in 1923 (1920s Fashions for Women)] and ushered in the modern era of fashion which conceived the idea of erotic beauty. The transform ation of woman from being an object of beauty to becoming a futurist machine was kick-started. ‘Chic’ became a vogue word. And there was no looking back. So we see the cumbersome Victorian clothing gradually losing ground. Crinolines, rear-enhancing bustles and restrictive corsets passed into oblivion, thankfully causing a steep decline in the incidence of ptosis. Lighter, brighter and daringly shorter dresses, straight-line chemises, nemo-flex brassieres, sleek, masculine or boyish look, flat chests with bandeaus, shingle cut and Bubikopf or the bob cut (popularized by actress Louise Brookes) formed the order of the day. The Basque dress or Robe de Style which clubbed the features of straight silhouette and belled skirt was very popular. Make up, in particular, was another ‘shocking’ development. Rising hemlines of the flappers, who characterized the revolutionary spirit of the typical jazz age woman, made dancing the Charleston, for instance to a tune of Duke Ellington or to the frenetic sounds of Bix Beiderbecke, easier. Light weight undergarments made it easier to play sport and drive automobiles. The Women’s Fashion Institute designed the ‘one hour dress’ in 1926 (Flapper Fashion). For the first time in history, pleats, gathers and slits ruled women’s fashion, liberating women from constricting clothes, though the Great Depression, for a while, brought about a roll-back towards conservative wear (The History of 20th Century

Polymorphism In Object Oriented Design Information Technology Essay

Polymorphism In Object Oriented Design Information Technology Essay In large scale organizations measuring software quality is complex for the development of software product. High quality software would enhance the potential reuse of the software and reduce the software maintenance cost. Many of the presently available software metrics are applicable when the particular software product Polymorphism has been assured to improve reusability technique which is achieved through the POF, Polymorphism factor derived from the MOOD (Metrics for Object oriented design) metric. II BACKGROUND Software metrics are considered as key facts or ways to measure any kind of software product from the starting phase to the obsolete phase. These software metrics are available and used throughout the project to assess the software quality, cost estimation and time consuming to develop a software project. It is declared that the Traditional metrics are not applicable to Object Oriented design since Object Oriented Software metrics are applicable to class level and other characteristics such as abstraction, inheritance, modularity and Polymorphism. These metrics convey the software engineer how the modifications can be made in order to reduce the cost effectively and time consuming while designing software and to improve the quality, continuing capability and profitability of the software. In [7] nearly 100 metrics had already given to find out the complexity of the software code and in [8] they were more than 150 metrics are proposed in the field of Object oriented paradigm. The Object Oriented software metrics are differentiated into two types namely Static and Dynamic. Dynamic and Static code analysis are done during source code reviews. Static metrics are derived from the measurement on static analysis of the software code. Static code analysis is performed without executing any of the code. Static analysis is better to understand the security problems within the program code and can easily identify nearly 85% of the flaws in the programming code. Dynamic metrics are derived from the measurement on dynamic analysis of the software code. Dynamic analysis is based on the studying of the code behavior during execution. Earlier major work was focused on static metrics but more attention has given to Dynamic metrics as the results are derived at run time. In this binding it can be substitute to forms or objects that are related to polymorphism factor at the time of execution. III FORMS OF POLYMORPHISM Polymorphism is considered as one of the salient features of Object oriented Programming languages. This feature mainly deals with reusability technique. In object oriented analysis Polymorphism roots from message passing, substitutability and inheritance which yields to is-a relationship. This similarity may allow achieving variety of technologies like code sharing and reusability. Mainly Polymorphism is differentiated into 5 types in Object Oriented paradigm like generics, pure polymorphism, overloading, deferred methods and overriding, Both Polymorphic classes and methods are known as Generics. This paper mainly focuses on three definitions mainly Overloading, Overriding and pure polymorphism. Pure polymorphism is achieved by implementing same function to different types of arguments. Method overriding is possible when the implementation suggested in the super class is modified in the sub class. Next to that method overloading is achieved when different methods having same name. Method overloading is also known as Adhoc Polymorphism. The differentiation on Polymorphic behaviors in C++ are related to runtime binding decisions which are overriding methods or virtual functions and compile time linked decisions which are over loading functions. From this design polymorphic functions are categorize into different types. The Polymorphic member functions can formerly defined as where in a new declaration these characteristics may alter while the other remains the same. This will generate different types of Polymorphic implementations that affect the quality on Object Oriented paradigm. A) Pure Polymorphism This behavior is also known as parametric overloading where it can be identified similar name with different signature which is inside the class scope. This behavior inside a class scope is identified by implementing more functions with other signatures. B) Static Polymorphism In Object Oriented design methods related to similar name but with other method signature can be identified in other classes related and which are unlinked by inheritance relationships, which is also known as Overriding behavior. In C++ they can be categorized overriding methods into two different forms like virtual and non-virtual methods. The non -virtual overriding functions can be identified by other signatures which are related to other declarations. As they are based on Static binding can be called this from static Polymorphism. C) Dynamic Polymorphism This behavior has the capability to use the similar name with similar signature in an overriding function. In C++ it is called as adhoc polymorphism as it invokes run time decisions at execution by the compiler. Combination and Specialization are the two features derived from the Object Oriented design which results Dynamic and Static Polymorphism. The polymorphism forms discussed above consists single perspective where each pattern may be identified and combined to achieve class inheritance relationships. Fig 1. Simple Inheritance. Simple Inheritance states that one Parent can have many children, but each child can only have one Parent. Fig 1 illustrates that A is a Parent, B and C are Children to Parent A. Likewise P and Q are children to Parent B and M and N are children to Parent C Table 1 shows the derived set of metrics where it can be taken as the combination of dynamic and static polymorphism forms with respective to the simple inheritance relationship [2]. IV POLYMORPHISM FORMS METRICS Metrics Definition SPD Static Polymorphism in Descendants. DPA Dynamic Polymorphism in Ancestors DPD Dynamic Polymorphism in Descendants SPA Static Polymorphism in Ancestors. OVO Overloading in Standalone classes Table 1 In Object Orientation paradigm, generic methods and classes are able to decrease the description of newly created objects and classes. The OVO (Overloading in Stand-alone classes) metric is designed to calculate the intensity of method genericity in a class scope by numbering and calculating the function members which designed the same function. The Static and Dynamic metrics are designed to calculate each Static and Dynamic binding separately in Object oriented paradigm. Example 1 Class P { void a (int k); void a (float l); void a (int i , int l); void b (); void b (int n); } Class Q : public P { void a (); } Class R : public Q { void a (); void b(); } Class S { void a (); } A) Data Validation In order to validate Polymorphism metrics, product metric validation methodology is very useful to validate other suits of Object Oriented design metrics. This validation represents the capability of polymorphism metrics to predict the fault prone functions. Here the data is gathered from an open multi-agent systems development environment, known as LALO. [2] LALO has been maintaining its development since from 1993 at CRIM (Computer Research Institute for Montreal) where it approximately includes 40k source lines of code and 85 C++ classes. Here the analysis has been obtained from the Source Lines of Code, information about its classes and fault related data. B) Descriptive Statistics Table 2 shows the analysis for descriptive statistics which are related to Polymorphism metrics. Due to the reason that LALO objects contains very low and minor inheritance depth and week variance has been calculated from the descendants of polymorphism namely SPD and DPD. Here it is confirmed that week distribution of polymorphic forms is due to low usage of inheritance in LALO classes. Metric Max Min Mean Median StdDev OVO 15.00 0.00 3.47 3 2.71 SPA 18.00 0.00 3.54 1 4.63 SPD 111.00 0.00 3.73 0 13.87 DPA 5.00 0.00 0.73 0 1.29 DPD 28.00 0.00 0.77 0 3.35 SP 111.00 0.00 7.28 3.5 13.90 DP 28.00 0.00 1.50 0 3.49 Table 2 C) Polymorphism metrics and MOOD metrics Table 3 shows the correlation among the five polymorphism metrics and POF (Polymorphism factor) measurement derived from the MOOD (Metrics for Object oriented Design) metrics [6]. As per the analysis the POF from the MOOD metrics, SPA and DPA metrics from the Polymorphism metrics are maximum correlated as they captured the same forms of polymorphism namely overriding. OVO, SPD, DPD and POF have very poor correlation. OVO SP DP SPA SPD DPA DPD Pof .06 .50 .42 .98 .02 .72 .00 Table 3 D) Correlation between Polymorphism metrics. SPA and DPA calculates the count of member functions that are overridden between a class scope and its ancestors. This states that dynamic polymorphism and static polymorphism have similar quality impact in ancestors relationship. Since DP and SP are counted from the metrics SPA, DPD, DPA and SPD where DPA and SPA are nearly correlated and DPD and SPD calculations are not statically specified in the dataset and the expectations are SP would be maximum correlated with DP. SPA SPD DPA DPD SP DP OVO .06 .05 .04 .07 0 0 SPA 1.0 .03 .71 .00 .51 .42 SPD 1.0 .01 .67 .27 .13 DPA 1.0 .00 .43 .63 DPD 1.0 .22 .29 SP 1.0 .70 Table 4 F) Relation between Polymorphism metrics and Chidamber and Kemerer metrics. Here is the comparison between Chidamber and Kemerer (CK) metrics and Polymorphism metrics [9]. The six CK metrics are RFC Response for a Class. DIT Class Depth Inheritance Tree. CBO Coupling between Class. WMC Weighted Method per Class. NOC Number of Children. LCOM Lack of Cohesion among methods. a) DIT DIT is used to calculate maximum tree depth from class to root class. The high DIT has been found to lead more faults. However, more the tree depth, more the reusability factor because of method inheritance. Fig 2 Fig 3 Fig 4 Fig2 resembles simple inheritance where each parent can have more than one child but each child must have only one parent. In Fig3 P and Q are combined and inherited from Parent A and Fig4 shows high DIT as it illustrates high tree depth inheritance. b) NOC NOC counts the immediate sub-classes of a root class. As maximum DIT indicates the high tree depth, NOC counts the breath of the class hierarchy. High NOC increases the number of child classes, high reuse of the Base class is possible. High NOC has been found to lead low number of faults because of high reuse of Base class which is more desirable. Table 4 shows the values to compare only two CK metric represents a relation with two polymorphic metrics [2]. The highly related pair of metrics is NOC-SPD. Also the highly correlated metrics is DIT-SPA where these two relations are highly expected. Table4 Children in the classes are counted by NOC metric. Level of coupling is measured by SPD metric due to static Polymorphism having its descendants. Due to static polymorphism chances of having coupling is higher as greater the number of children. Inheritance depth tree is calculated in a class by using DIT metric. As per the static polymorphism, level of coupling with class R in Example 1 and its ancestors is measured by metric SPA. While measuring different forms of class dependencies in Polymorphism, it is observed that CBO represents a very low correlation with polymorphism metric which is calculating algorithm class coupling. Hence it is confirmed that the polymorphism metrics can get variety of variations of class scope coupling which are not highly captured by CBO metric [2]. A backward and forward logistic regression is performed while examine the relationship between CK metrics and Polymorphism metrics [2]. By combining these two Object oriented metrics a significant methodology related to fault prone class has been implemented. V REUSE, REUSEABILITY METRICS IN POLYMORPHISM As I discussed earlier, Reusability is the key concept to achieve Polymorphism, following are the metrics discussed under the concern of Reusability [1]. The key factor of developing and upgrading software by using the existing software has made our Engineers to focus more on systematic re-use where the organizations can make most benefit and get extensive advantage from the idea of reusability. A) Reuse and Reusability Metrics Reuse metric is obtained from number of efforts that takes place in the research area on economics of reuse. If the return on investment is positive then it can be analyzed that reuse is beneficial. It consists of maintaining the cost for reusing the libraries, modifying costs and reusable maintenance from the existing property, cost of searching, evaluating, identifying, integrating and selecting the potential articrafts. Different economic metrics has been introduced to measure the reuse metric which implements the cost benefit ratio. Durek and Gaffneys reuse metric based on economic factor is proposed and useful to measure the break -even point and the reusability cost. COCOMO based reuse model is used to calculate the total time that takes to implement the software with the functionality of reuse which is proposed by Gustafson and Balda [1]. Durek and Gaffneys reuse economic metric is represented as C= (b+E/n-1) R+1 Where C = Cost related to Software Development, usually less than 1. R = ratio of the reused code in the project. E = Cost to make code reusable, which is cost related to new code which is used to develop a component for reuse. B = reusing existing code in the project where the cost related to new code like adaption, searching and adaption cost. n=the number of reuses expected. As our interest is ultimately in measuring the cost but these metric needs the cost of creating the reused articrafts as input. B) Reuse Metric Level This reuse level metric is introduced by Frakes which implements threshold levels to gather and remove the items which are not reused very often. Suppose if the threshold level is 4 the object should be called 5 times for reuse. This metric also varies between the external and internal level. Total reuse level=Internal + External level. External reuse level=EU/T and Internal reuse level=IU/T. T=both internal and external items in the system. IU=number of reused external items EU=number of reused internal items. Each reused item which is EU and IU must have the values either 0 or 1.If the threshold level is less than the item reused then the value is always 1 or else it will be 0.This measure does not consider the number of items reused. Here this metric uses item instead of SLOC, as each item varies, some item would be large or small when compare to other items. In the later version of this metric, depending upon the size of the item, assigned a weight to each item. This is done because the threshold levels should be same in order to compare the projects. C) Measuring Polymorphism As the process would vary from execution to execution, the problem is with while measuring polymorphism, exactly what happens within an application. Example 2 List l; If(condition){ l=new ArrayList(); } else l=new Linked List(); l.add(); In Example 2, the Linked List implementation and the Array List implementation depends on the external condition. There is no prediction that the condition is always satisfied, with the implementation of the polymorphism. Dynamic analysis is the right way to measure polymorphism as it gathers the information at run time. Following is the metric that defines the amount of polymorphism has occurred [1]. PBI=UPD/Total Dispatches. Where PBI=Polymorphic Behavior Index. TD=UPD+NP. UPD= Polymorphic Dispatches that are unique NP=Non-polymorphic dispatches that are unique. TD=Total Dispatches. In the above example, List l=new Array List (); The List interface will declare the variable l and it is said to be Declared Interface. If the condition is true. Then Array List () is the Dispatched class in this Example. Both the Class and Interface are different and the relationship can be given as Conforms and implements. An interface might not directly implement by a class, it can be accessible through parent class. The actual method which is processed is the deepest inherited implementation of the method. Example 3 Class A{ void method 1(){} } Class B extends A{ B b=new B(); b.method1(); } The b.method1 () is dispatched to A.method1 () because it is the deepest inherited implementation method. Polymorphic Dispatch will be observed when the Dispatched Class and declared interface, both are different. Non -Polymorphic Dispatch is observed when the Dispatched Class is same as the declared interface. Example.4 Interface P{ a (); } Class Sample inherits P{ a();{} b();{} } Class Sample2 extends Sample{ b();{ super(); } } When Sample sp=new Sample(); sp.a(); The sp variable relates to a Sample object. The Sample class consists method a() implementation, so Sample.a() will be dispatched. The Dispatch class, Sample is same as the declared interface, so this is considered to be a Non-Polymorphic dispatch. Sample2 sp2=new Sample2 (); sp2.a(); Since sp2 relates to an object of type Sample2 the dispatched method is Sample a ().Although Sample2 not requires a method a() implementation ,Sample.a() is the deepest inherited implementation method. Sample is the class that is dispatched here. This is Polymorphic dispatch as the Dispatched class is Sample and declared interface is Sample 2. P sp3=new sample(); sp3.a(); Here in this case, since Sample.a() is dispatched, the Dispatched class is Sample and Declared interface is P . As Dispatched class Sample and Declared interface P both are different this is Polymorphic Dispatch. D) Inherited Method Call using Inherited Class. Sample sp4= new Sample2(); sp4.a(); Here the dispatched method is Sample. a () while declared interface of sp4 is Sample. So this is considered to be a Non polymorphic dispatch as both the declared interface and Dispatch class is same, Sample. Sample sp5=new Sample2(); sp5.b(); Here sp5 implements the inherited method b() from Sample2. Sample2.b() overrides the Samples b() and this inheritance substitutes the functionality from the Samples b() method, Here, dispatched method is Sample2.b() as it is the deepest implementation method . Hence it is known as Polymorphic dispatch as the Dispatch class is Sample2 and declared interface is Sample means both are different. ` VI INTERNAL AND EXTERNAL REUSE Software reuse is often differentiated as External reuse and internal reuse. Considering internal reuse, these are the calls made to the desired code that is previously mentioned for the given application. External reuse is considered when calling the code that is coming from external source to the application of the project. When comparing both the internal and external reuse, external is more beneficial than internal.But both internal and external reuse are been used, for instance if the developer reusing the same method rather than developing new methods which performs the same action. Internal methods are created by the application developers, which are defined as methods. Internal methods also include implementing the custom code extending the API and the API interface. When any method calls an internal method then internal method call is generated. Generally it happens internal methods calling to internal methods. Sometimes API will call these internal methods when these methods are passed as handlers into the API.As this external method to internal method calling is a strategy of application developers decision, these are still considered as an internal method call. External methods are obtained from external source where developers cannot modify it, which includes external libraries and API. Suppose if internal method calling an external method then call to the external method is generated. Here it must not be considered external to external method calling. Example 5 Class sample extends java.lang.Thread { void method p () { method q (); } void method q (String s) { System.out.println (This is an Example); } public void run () { method p (); } public static void main(String args[]) { this .start() } In Example 5 when the Sample class is executed, Java launcher calls the main () method. As the Sample class extends thread class and calling the start () function will insert the Thread class in Java Scheduler. As a consequence Java scheduler calls run () method, where the run () calls the method p (), which in turns calls the method q().method q() internally calls the System.out.println(). For instance when System.out.println () is executed, many internal API callings will happen like PrintWriter called by String Buffer. However these are not considered as external or internal method calls. VII TOOLS FOR SOFTWARE METRICS Fig 5 Process for Dynamic Metrics A) E-MTRACE The process of evaluating the Polymorphism metric is the comparison held in same domain of Polymorphism with two software applications, where it is manually determined by the source code to examine their reusability and reuse issues of performance. In order to avoid or remove unnecessary values like system method calling that is invoked by JVM there is a need of filter. The data which is filtered is examined to recognize non-polymorphic and also polymorphic dispatches from where the values are derived. The tool that is implemented to capture all this related information is known as E-MTRACE [1].This tool uses JVMTI, JVM Tool Interface that is examined and control s the process of execution running in the JVM (Java Virtual Machine). File Hook is used to insert the byte codes into methods.JVM is interrupted by the File Hook, when the JVM is loading java .class file to heap. The File Hook inserts the profiling instrumentation code and interprets .class file before calling any method. During runtime the instrumentation code can be inserted. The instrumentation code is executed while calling a method. The program stack is used by the instrumentation code to recognize the Dispatch class. Then to trace the Declared interface it uses the Local Variable Table. EMTRACE Analyzer tool would be processed, once the Dispatched class and the Declared Interface are identified, which evaluate the list of non polymorphic and polymorphic dispatches results. B) Resharper and CodeRush. Resharper and CodeRush are the tools available to extend the native functionality of Microsoft Visual Studio latest versions These tools executes the static analysis of the code like error detection without compiling the code. These tools provides enhanced features like error correction, code generation, syntax highlighting, optimization, formatting and many other features. VIII CONCLUSION Considering quality factor, it is not an easy task to examine and to avoid the complexity, several properties mainly Polymorphism factor in Object oriented design has proposed and paid special attention by Application developers and Software Engineering Society. This Paper mainly discussed on Polymorphism metrics related to Static and Dynamic behavior with respect to Object Oriented Analysis [2] and focused on the Comparison among Chidamber Kemmerer metrics, MOOD(Metrics for Object Oriented Design) metrics and Polymorphism metrics. It is noted that (NOC-SPD) (DIT-SPA) from Chidamber Kemmerer and Polymorphism metrics are highly correlated [2]. In addition to that this Paper also discusses about tools like E-MTRACE which deals with Polymorphic behavior. E-MTRACE is a tool that is developed to measure java applications [1]. This Polymorphic behavior metric is used to examine the interface that has most polymorphic dispatches. So these interfaces may introduce the basis for new technology frameworks and APIs. Moreover, it is necessary to note that the metrics and measures capture the valuable related data from the starting phases of the product development lifecycle giving Engineers a chance to evaluate early fault prone area and advancing the quality factor and to maintain the continuing capability of Software product.

Com, 2014). † In this paper, the identification of an innovation, and plan for implementing the innovation, in the current workplace that I am working for, will be described in full detail. The innovative product that will be Introduced to the workplace Is called the â€Å"Freedom walker. How many Individuals get tired of slating down all day at a desk?Another complaint that is heard, quite often within the organizations is, â€Å"l am overweight and I do not have the time to make it to the gym. † Well, now here is the perfect solution. Freedom Walker will give Individuals the opportunity to either, remain seated at the desk while working or they can chose to get up and begin to exercise at the pace they feel most comfortable. The high-quality product will be made to last and it will give employees the freedom of exercising while working (Treadles, 2014). Freedom Walker Is going to solely be Intended to run in slow speeds.One of the great things about this product is that unlike regular treadmills. He Freedom Walker will not overheat (Treadles. 2014). For which, giving individuals an unlimited amount of time to be on the treadmill while working. The control panel can be placed on top of each employee's desk. And will have a 10-inch cord connected to the panel and the Freedom Walker. On the control panel, employees will be able to see how long they have been walking. The employee will also be able to keep track of the amount of calories that are being loss with the freedom walker.The Freedom Walker will also have an attached Emergency cord that all individuals who use this product must wear while in action. The Emergency cord Is In case of any emergency, the employee will be able to shut the machine off The Freedom Walker also comes with a strong rubber mat that should be placed on top of th e tread, to reduce the sound and avoid distraction (Treadles, 2014). The speed of this product will not go above 4. 0 MPH (Treadles, 2014). The reason that the machine will not go above the speed of 4. Is to avoid distractions on the phone with customers, such as loss of breath or Incorrect grammar spelling on the computer because of not being able to concentrate. For safety of each employee, the aching is limited to 4. 0 MPH. The Freedom Walker will not have much assembly required. The control panel is connected to the treadmill, Just simply connect the ‘OFF The design will begin with the CEO and upper management, and then will of course go down the list for each individual within the organization.It is a proven fact that the obesity rate within the United States has more than doubled in adults and children since sass's (Food Research and Action Center, 2014). The leading public health problem within the United States is obesity (Food Research and Action Center, 2014). Withou t any discrimination, the majority of the employees within the organization that this innovative idea will be implemented in, are overweight. Below is the chart from the Food Research and Action Report that shows the percentages of each ethnicity and at what percentage they are overweight.How can it be possible that a Health insurance company is selling insurance, but have the employees unhealthy and overweight? There is going to be a weekly goal that each individual will write-out for himself or herself when using the Freedom Walker. The organization will have to see some type of improvement in all employees. If, there is no improvement seen thin several weeks, then disciplinary action will be enforced. Once there is improvement noticed, that is when the organization will begin to offer incentives. The incentive that will be granted is that the company will pay for half, of each individuals health insurance premium.This could definitely guarantee success, especially now and days th at health insurance premiums are so expensive. The impact that this innovative process will have within the organization is going to be drastic. This will not only help the employees but will also help the customers as well. The innovation process, will allow employees to take stand about prolonged sitting. Researcher suggest that prolonged sitting is bad for one's health (Neoprene, 2013). There have been scientists that compare prolonged sitting to smoking (Neoprene, 2013).The Freedom Walker should help every individual begin to feel fit and begin to have a more positive attitude (Neoprene, 2013). This change in attitude and in oneself, innovation process is going to be an incremental innovation. As stated above the process will begin with the CEO and upper management. Once the change is seen in hose areas, then the process will begin to trickle down the totem pole as it has been heard. So, as the article states by the incremental innovation web page, â€Å"Slow and Steady Wins th e Race (Innovation Management Community for Practitioners, 2014). Incremental change is not about making a change happen instantly (Innovation Management Community for Practitioners, 2014). â€Å"The reason incremental innovation is so popular, is because it has reduced risk in comparison to radical innovation (Innovation Management Community for Practitioners, 2014). † Furthermore, once a equines has a manufactured good up and running it tends to have built up substantial amount of human capital and competencies so the business may as well dedicate time to creating it better or reducing costs (Innovation Management Community for Practitioners, 2014).Four Stages of the Research Cycle There will be seven steps to the innovation process and they are 1 . Thinking, 2. Portfolio Management and Metrics, 3. Research 4. Insight, 5. Innovation Development, 6. Marketing Development, 7. Selling (Morris, 2013). The way that the innovation will be measured will be â€Å"R&D Impact = Gros s Margin / R&D Spend – This is an â€Å"old† Bill Hewlett and David Packard metric they used to guarantee suitable return for the R&D effort being invested (McKinney, 2010). † â€Å"Why gross margin, one would ask? McKinney, 2010)† â€Å"The assumption is that if you assemble a better mouse trap, the customer will reward you with a margin premium which will show up in gross margin (McKinney, 2010). † â€Å"Target: Assess your competitors and you want to be in top quartile (McKinney, 2010). † Innovation takes time and dedication. In order for a company to be successful in the implementation of an innovation there needs to be, a lot of research and date corded. An innovative idea cannot Just be something that someone brings up and it happens.There has to be comparisons to other products and reports showing the business/organization why that innovative idea would be better than any other idea. The Freedom Walker would be a great innovative idea because it would help save the lives of many people who may be struggle with health issues due to weight problems. I believe that not only should the company that I am currently working for, use the innovative idea, but that all companies that have customer service representatives. Customer Services Representatives are mandated to sit at their desk for 8-10 hours a day without being allowed to move from the chair.Production and quality is something that is counted against the individuals who do move from his/ her chair, which then causes disciplinary action. This is an act that is inhumane and I believe that something should be done about it. So, everyone that has a business with CARS and Data Reps. Let try Freedom Walker and lets see how great of an impact it will have on not only the company but on the employees as well. References childhood and adult obesity in the United States.

How does Hardy use language and poetic form to convey meaning and ideas in ‘Wagtail and Baby’?

The poem ‘Wagtail and baby’ is a commentary of the observations from the perspective of an infant by the side of a ford. The focus of the baby is the wagtail and it watches as various animals approach it. What causes the baby confusion is the animals cause the bird no stress, but when a man approaches the bird flys swiftly away in ‘Terror’ before he even gets close. Thomas Hardy has done this to show how the bird is at peace with nature and other animals and human involvement disturbs the ordinary harmony of nature.This refers to Hardy’s views on industrialisation at the time and how the greed of men was affecting and destroying the natural world. This creates an air of irony; as humans try improving their lives they deprive wildlife of theirs. The poem is arranged in quatrains with alternating rhyming couplets (ABAB). This creates a childlike quality to the poem like a nursery rhyme which compliments how it is written through the eyes of an infant. T his reflects how everything is new to the baby and it watches and learns from everything around it.The four quatrains each describe a new animal that comes near the wagtail. The way each is different and they come one after another shows how it is happening in that moment. The language he uses helps to portray his ideas in the poem. Again Hardy adds to the childlike theme by referring to the wagtail as a ‘birdie’ in the second stanza, this is the sort of thing a child would say on seeing a bird. His style is detailed and the use of poetic devices such as alliteration creates vivid imagery.Alliteration such as ‘blaring bull’, ‘a stallion splashed’ and as he describes the mongrel as ‘slowly slinking’ portray a certain movement which the reader then picture in their minds. The movement of the bird is also described in detail the use of verbs ‘twitch and toss’, ‘clip and sip’ showing sharp, quick movements as if the bird is slightly on edge until realising it is only a fellow animal nearby. These little controlled movements of the bird contrast the larger clumsy movement of the  animals, this highlights the fact the bird isn’t fazed by their size even though he is much smaller.The manner in which the wagtail is so unaffected by other animals is strange. The ‘Blaring bull’ is a great powerful animal and is associated with aggression and yet the tiny wagtail does not see the bull as a threat. When the ‘stallion splashing’ causes the bird ‘nearly sinking’ in the water it manages to ‘hold its own unblinking’ doesn’t even bat an eyelid though something so big is near despite the obvious disruption and the fact it could easily hurt the fragile bird.Even the mongrel ‘slowly slinking’ has no effect on the bird, though ‘slinking’ can be associated with hunting and a stalking prey which should alarm the b ird as it is vulnerable. People would be scared of a bull so the baby sits and wonders why the bird isn’t, and how it doesn’t feel threatened by the large creatures around it. These all show how the wildlife are at peace with each other. That is what makes the last stanza so profound that the ‘perfect gentleman’ is the one to make the bird ‘disappear’.When forming the image of a ‘perfect gentleman’ in your mind, someone high up in society, respected and conducts themselves within the rules of society is what we expect. It seems odd that the bird would be afraid of a man when he causes no disruption to it and isn’t even close. It’s as though the man is not part of their world so the bird is unfamiliar with his presence or has seen other men before hurting nature. Even though the man is the best in human society he still scares the bird like a predator would, Hardy has done this to show even the best of us are seen as evil by nature.Something else that adds to the shock of this is that the baby has been sat watching and the bird was not afraid. Hardy has done this to show the baby is innocent and naive and has not yet turned into the greedy monster that is man. The baby causes no threat and because of its innocence is accepted by nature. The poem ends with ‘The baby fell a-thinking’ this is showing that the baby is confused because even though it doesn’t yet understand the world it can’t see why the bird would be scared of a human but not a big animal.The baby has only known the man caring for it so has not seen the side of man that the wagtail has. Thomas Hardy uses poetic devices to convey his ideas within this poem. He uses irony to show how humans try to improve their lives with industry and in turn destroy the habitats of wildlife. Hardy uses detailed descriptions to create vivid imagery and contrast the difference between man and animal again showing irony as the one that made the least disruption frightened the bird away. He uses alliteration for emphasis and his structure to reflect the state of mind of the baby viewing the scene. ï » ¿How does Hardy use language and poetic form to convey meaning and ideas in ‘Wagtail and Baby’?

Drugstore and Soda Fountains Essays

Drugstore and Soda Fountains Essays Drugstore and Soda Fountains Essay Drugstore and Soda Fountains Essay During the early 1900’s in America, the average drug store is comprised of three parts: pharmacy, retail sales, and the ‘soda water fountain’. The soda fountain is a dispenser of flavored syrups and carbonated water. Soon enough soda fountains were also used to describe ice-cream parlors, while counters in pharmacies started selling soft drinks (Leonard, R. B. , 1916, p. 322; Soft drinks, 2007). The soda water fountain’s popularity can be credited to the creativeness of American pharmacists. Already in the business of selling soda water, the American pharmacists later added flavors derived from fruits, nuts, berries, roots, herbs, and other plant sources to the unflavored mineral water. Various ingredients from plants and trees were used such as birch bark, dandelion, sarsaparilla, and other fruit extracts, some of which were purposely chosen for their medicinal value. The other additives were chosen to enhance the appearance of the clear sparkling mineral water. City dwellers as well as small town folks enjoyed drinking soda in these establishments. However, the fame of soda water fountains started to collapse with the advent of fast foods restaurants, commercialized ice cream, and bottled soft drinks. But this did not mean the collapse of the soft drinks industry. In fact, soft drinks underwent much development through time. There have been many different kinds of carbonated soft drinks formulated throughout history and various companies engaged in its production. Nevertheless, this paper will focus only on the two giants in the industry: Coca-cola and Pepsi Cola. Coca Cola What is today the big name ‘Coca Cola’ was discovered and established in 1886 by a pharmacist from Atlanta, Georgia named Doctor John Pemberton. By concocting a medication that contained extracts of caffeine-rich kola nuts and of the cocaine-rich coca plant to cure headache and hangover, he produced Coca-Cola (Carbonated Beverage, 2004, p. 8495). Ingredients of the Coca-Cola formula and the how it was manufactured by Doctor John Pemberton is discussed in a book by Mark Pendergrast entitled, ‘For God, Country and Coca-Cola’. Mr. Pendergrast was given the opportunity to access archival material of Coca-Cola and to interview people within Coca-Cola. This privilege gave him important data from Coca-Cola sources (The Coca-Cola Recipe, 2007). It was established in his research that the production of soft drinks takes quality. For instance, even though the water that is used in its manufacture already comes from a safe and potable source, further purification processes are held in place to ensure the quality of the product. In manufacturing soft drinks as a whole, measures must be taken to ensure purity and uniformity of the ingredients because any impurity that is not screened would be carried on to the final soft drink product (Soft drink, 2007). John Pemberton constructed a primitive filtering contraption in his house made of sand from a nearby river. It is in this primitive filtering contraption that he pours the flavoring mixture made from his recipe to remove solid particles and whatever impurities the water from the municipal supply and other items in his syrup mixture may still contain (The Coca-Cola Recipe, 2007). Before John Pemberton died, ownership of Coca-Cola changed hands in 1887. The new owner Asa Candler, an Atlanta pharmacist and businessman, also changed Coca-Cola’s formula. Candler’s intention in doing this was to prohibit imitators from producing soft drinks which are similar to Coca Cola since a bunch of people already knew its original formula at the time Candler purchased the rights to produce it exclusively. Further, Candler made some additions in the formula such as preservative in the form of glycerin, phosphoric acid as replacement for citric acid, reduction of its caffeine content, and removal of cocaine as an ingredient. In the revised formula of Asa Candler, the ingredients were sugar, caramel, caffeine, phosphoric acid, coca leaf cola nut extract, lime juice, flavoring mixture, vanilla and glycerin (The Coca-Cola Recipe, 2007). At present time though, changes have already been made in the aforementioned Candler’s formula including. With corn syrup now used as a sweetener instead of sugar, its packaging also evolved with the changing demands of the consumers. Today, far from the original sodas of the drug store’s soda fountains, carbonated soft drinks are packaged for sale in various containers, such as aluminum or tin cans, plastic bottles, and glass bottles. The company also released a ‘New Coke’ formula on April 23, 1985, but it did not do well to those accustomed to the old Coca-Cola flavor so the old formula was reinstated. Coca-Cola’s success and popularity can be attributed to Asa Candler’s aggressive marketing of Coca-Cola. Together with Coca-Cola’s success, the demand for syrup sales increased. The company sells syrup to independent bottling companies which have been given license to sell the soft drink. Nowadays, Coca-Cola soft drinks that are being consumed each day rise up to 9 digit figures (Bellis, 2007). Pepsi-Cola In 1898, Caleb Bradham, a pharmacist in North Carolina, had a soda fountain in his drugstore. This is where he served his customers refreshing drinks: carbonated water mixed with medicinal and flavorful ingredients which he himself chose. What he termed as ‘Brad’s drink’ became his infamous drink in his soda fountain. The ingredients of the said drink were sugar, carbonated water, rare oils, pepsin, cola nuts and vanilla. He created the drink back in 1893 (Bellis, 2007). This particular concoction is to become ‘Pepsi Cola’ in 1898. It was renamed after the key ingredients, pepsin and cola nuts. In that same year, Bradham purchased from a competitor that went bankrupt the trade name ‘Pep Cola’ at the price of 100 US dollars. In June of 1903, the name Pepsi Cola was first introduced and trademarked. It was Bradham’s neighbor who took the job of designing the first ever logo of Pepsi Cola. Business was successful until he gambled on the fluctuations of sugar prices during World War I resulting in the bankrupt of Pepsi Cola in 1923. The year 1931 saw to the transfer of Pepsi Cola ownership to the ‘Loft Candy Company’. The then company president Charles G. Guth changed the Pepsi Cola formula. However, this change made it difficult for Guth to make Pepsi Cola a winner in the industry so he resorted to selling Pepsi Cola to the Coca-Cola Company, but to no avail. 1940 saw to the creation of Pepsi Cola history because it was at that time when the first commercial jingle, entitled ‘Nickel Nickel’, was made and aired throughout the United States of America (Bellis, 2007). Like its competitor, Coca-Cola, changes were introduced in Pepsi Cola. In 1964, ‘Diet Pepsi’ was offered in the market.

Forensic science expert witnesses should be free to express their Essay

Forensic science expert witnesses should be free to express their opinion as they see fit - Essay Example Whether or not the incidence of human error within the court justice system is intentional or unintentional , miscarriage of justice is considered as a serious social issue that could destroy the ability of the court to promote a fair legal justice system throughout the United Kingdom. To avoid destroying the credibility of UK’s legal system, most of the long list of past and current miscarriage of justice cases are kept unpublished.In case the defendant is not guilty of a crime, Layne explained that miscarriages of justice can occur each time an innocent person is convicted of a crime that was committed by another person . This can happen in times when the defendant has been unfairly convicted because of failure to receive a fail trial. There are also situations wherein the innocent defendants can also be detained in a prison cell even though the innocent defendant has not been found guilty of a crime .... This can happen in times when the defendant has been unfairly convicted because of failure to receive a fail trial. There are also situations wherein the innocent defendants can also be detained in a prison cell even though the innocent defendant has not been found guilty of a crime3. On the other hand, miscarriages of justice can occur in case the judge let go of a guilty defendant. In case the life of a witness or one of the jurors has been seriously threatened, there is a strong possibility for a guilty defendant to be acquitted in a court trial. Extent and Limitations wherein Forensic Science Experts should be Legally Allowed to Freely Express their Personal Opinions as They See Fit Expert witness is referring to professionals with proper education or expertise in a particular field (i.e. psychiatrist, pharmacologists, neurologists, etc.) who could assist in solving a criminal case4. Their main role is to provide scientific-based evidences or testimony based on facts in the court . Over the past decades, expert witnesses managed to help in solving crimes by presenting scientific-based information that are useful in making the members of the jury decide whether or not the defendant is guilty of a crime. Even though expert witness could help the jury solve criminal cases, there are also some instances wherein the information coming from the expert witnesses could lead to miscarriage of justice5. Because of the increasing number of wrongful conviction in UK, several previous cases strongly suggest the need to develop and implement a new â€Å"corrective justice system† throughout the United Kingdom6. This is probably one of the reasons that had triggered the need to determine the extent and limitations wherein the

Macbeth Assignment Example | Topics and Well Written Essays - 500 words

Macbeth - Assignment Example After the king is dead, Macbeth utters these words to show how deeply he is moved by his death. Macbeth shows how much he loved the king and how his life was just perfect when the king was alive. If he had died before the king’s departure he wouldn’t have been alive to see him fall – such an emotional stir it creates in the minds of the listeners! The reason for this ‘love’ for the king simply dripping from his words is because Macbeth is now afraid, that Macduff knows it was him who killed the king. So to show his utmost devotion and servitude for the late king, he uses this concealed treacherous love bloom in the hopes of ridding himself of the stench of king’s blood. Such equivocation doesn’t really have two meanings, it is nothing but deceit, an artful lie to let the world know how much Macbeth loved the king. It is words like these that help evil geniuses like Macbeth build an honest repute with fraudulent methods. Macbeth was a general in King Duncan’s army it would have been so foolish of him to have openly criticized the king or to openly challenge him. His equivocal words like the quote above helped him to rank higher from Thane of Glamis to Thane of Cawdor and then to become the king of Scotland. In this last quote Macbeth gives his reason for not killing Banquo when he is talking to the murderers. The equivocation is in the sense that he is addressing murderers yet his intent is to share it with Banquo. Killing a man doesn’t really require killing him with one’s own hand. The better option is to get someone else do the job, this way there is always enough doubt to get away with the murder. Macbeth uses words such as â€Å"could† and phrases like â€Å"yet, I must not†. This is classic equivocation, deceit to let thanes know that he had all the resources to kill Banquo but he didn’t as they both share common friends (enough reason
