Art - Essay Example This blackboard is painted in black with some writings inside, and this creates attention to the viewer. On the left side below the blackboard is a chair, which seems to have been used in the ancient times. The chair is well decorated and design in a manner that creates attention to the viewer. On the right side is a cupboard and near to it is woman standing near to the cupboard. Additionally, on the forefront of the cupboard is a woman wearing a blue dress, which is not actually a dress but a painting decorated on the body; thus making it appear like a blue dress. The blue color offers the impression of hope, honesty and loyalty to the viewer. It also exhibit inner sanctuary and confidence; thus communicates or creates to the viewer the sense of calmness and peace. Down to the legs of the woman is a black painting, which appears like black shoes that she is wearing. The black color of these shoes communicates to the viewer about the power and authority. The black color can also imply submission because some experts argue that when a woman is wearing a black garment or shoes, the black to them implies submission to a man. The second art work which is written Sara Lighting is another artistic feature, which offers varied impressions to the viewer. First, the wall where the words are written has a smooth surface which glitters. In the middle of the wall is word written in block letters ‘Sara Lightening’ and immediately other words follows, which is ‘Courtney, Waiting Room, 2012, oil on canvas. This style of writing letters in block letters in the typography way is the core component of the design. Thus, it offers the reader or the viewer an insight or understanding the heritage behind the art work. It is one way through which the artists pass information to the viewers; thus making them to have a feeling of knowing more about what is inside the room. Axel and Nina (230) argue that one way of describing the technique of the

Social determinants of health - Essay Example Remarkably, the health situation in Australia is extraordinary and impressive in most aspects compared to other neighboring countries; however, the cancer issues continue to multiply creating the need to counter them and understand those affected for utter support. Definitely, cancer is an ailment that changes lives of most people with the survivors having positive outcomes resulting from well adjustment over time; nonetheless, there are still those that face daily challenges. The common health problems that result from cancer include weariness, aching, sexual complications, despair, apprehension and frame of mind deficiency; largely, these problems appear to be the core disruptors of the affected lives but the most frustrating are the social struggles (AIHW 2010). Typically, while undergoing treatment, most cancer patients are able to change their morals and objectives, perspectives on life and how they relate with others as part of the social development program: however, there are barriers such as occupational challenges, hitches with insurance and health worries that also negatively affect their social lives hence there still lacks a sheer solution. This article gives a brief analysis of the social impact on cancer evaluating the different social determinants of health relevant to the cancer and low socio-economic groups in Australia. Currently, cancer is the leading burden disease in Australia and has dominated for the last eleven years; the burden is a result of lives lost over the years due to premature death and disabilities from prostate, colorectal, breast, lung and melanoma cancers (CVA 2013). Occupational and social environment aspects of the infected affect the mortality rate; however, these are not the only core contributors but they are key determinants of a significant number of dissimilar cancers. The occupation determinant is about the exposures that people face in their workplaces; for instance, some of the machines and equipment used

Performance Analysis of Reusable Software Systems

Performance Analysis of Reusable Software Systems Monika Kalotra Dr. Kuljit Kaur Abstract: To improve the quality of software system, there is a need to eliminate or reduce the rework. Software reuse is one of the solution proposed for it. Software reuse involves reuse of existing software modules, also called reusable software components, while creating new software systems. In the context of software reuse, it is important to evaluate the performance of reusable software components as performance is a crucial factor in the selection of any third party or existing software components. This paper shows a comparative study on the performance analysis of four reusable software components-hibernate, spring, IBatis and EclipseLink. This paper presents the way to build a comparative analysis that shows the average execution time, average heap usage, and average CPU utilization of the reusable software components using java based VisualVM tool. Keywords: Performance, Software Reusability, java framework, CBSD. I. INTRODUCTION In 1968, to overcome the software crisis Mcllroy proposed the concept of software [1]. To build large reliable software systems in a controlled and cost effective way, he pointed towards the effective use of reusable software components [2]. The results of software reuse to improve the productivity of the programmer because with the reuse we can produce high quality software at a minimum cost and deliver it within a short span of time [6]. Reused software is of better quality than new software because it has been already tried and tested in other systems. There are two approaches for reuse of code: develop the code with reuse or develop the code for reuse. In either case, there is a need of measuring the quality of the reusable piece of software [8]. The reuse of program/software is a common technique which attempts to save time and cost by reducing duplicate work. This paper presents a comparative study on the performance of four reusable software components hibernate, spring, IBatis, EclipseLink. These are Object Relational Mapping based framework. They can be used in developing a Java application. These components map the java classes to relational tables in database with the help of SQL queries. Several SQL queries are executed on these components at the backend. In order to measure the execution time, CPU utilization of every executed SQL query, performance benchmarks are used. We make a comparison between these reusable components using java VisualVM tool. II. RELATED WORK To evaluate software reusability two approaches are used: qualitative and empirical [11]. The qualitative methods require significantly manual efforts and depend on a subjective value. Empirical methods depend on the objective data that can be collected with the help of some simulation tool. The performance metrics of component based systems, which are the challenging properties to predict and measure [4]. They have performed three case studies on performance analysis of real-time systems using Deep Compass framework. For performance analysis, software toolkit called CARAT is used for model synthesis and simulation. The performance of prediction methods based on models that support a development process from top to bottom, where developers create a new architecture and software components [3]. These methods rarely integrating existing components in the software architecture models. While there are many tools for performance measurement and profiling existing software components cannot be directly tested the performance when integrated into a model. A systematic approach proposed to software reuse are built to reuse and build by recycling [5]. The problems in software engineering is not a lack of reuse, but a lack of systematic reuse. They know how to do, but they do it informally. The concept of reuse is used to reduce the cost, effort and execution time for software development. Re also raises the productivity, maintainability and reliability of the software, which has been evaluated before in other software. Reusable software components framework is proposed. Empirical observations was made by applying the framework to the recording system C. The result clearly shows that the proposed framework to reduce the work of software developers, who needed a bit of effort to build reuse or build by recycling. The most complex components in the software development process is the database. The performance analysis of persistence framework explained in [15]. The complexity increases when the perspective differs of the interacting components. The performance comparison of two persistence frameworks namely Hibernate and IBatis using a banking database. Both the framework maps JavaBeans to SQL statements using a XML descriptor. The online banking application case study is used. Performance is measured using a java program which uses basic SQL operations on the banking database and the Round Trip Time is calculated and used to measure the way these mapping tools perform under various situations. The performance of both of these tools in single and multi-user environments are evaluated. Hibernate performs better because it supports lazy fetching and mapping associations. To develop the performance of software applications is a major problem in software applications. The solution is to avoid the assessment of late performance [10]. A prediction approach to provide the best solution to solve the problem. Three types of approaches to performance prediction used to know the measurement approach, the approach based on a model and a mixed approach. The main goal is to improve the performance of the software. Steffen and Ralf reported five factors that impact the performance of software component is the implementation components, resource conflicts, use patterns, platform deployment and required services. Quantitative approaches related to the objectives of the performance engineering of software to evaluate the software, which by focusing on quality factors of performance such as response time and throughput. In the end result, the hybrid approach is the best approach. III. RESEARCH METHODOLOGY A. Data Collection To analyze the performance of reusable software components, we have downloaded some jar files relevant to these reusable software components. A Java application can be started with a set of jar files. For implementing various libraries and plug-ins in java applications these jar files are used. The various jar files being used are mysql-connector-java, hibernate-core, hibernate-validator, jboss-logging-3.1.3.ga-sources, javassist, org.springframework, org.springframework.Expression, ibatis-dao, ibatis.jar, javassist, IBatis-common and eclipselink. B. Performance Metrics: VisualVM is a tool that provides interface for viewing detailed information about Java based applications [7]. VisualVM organizes data about the JVM software and presents the information that enables the developer to quickly view data on multiple Java applications. Java VisualVM can be used by Java application developers to monitor and improve java applications performance. There are four metrics used to analyze the performance of reusable software components. a). CPU Utilization: Using this metric, you can see how much of CPU is being consumed by database activities. CPU utilization is used to track CPU performance when running a specific piece of code. It is measured in %. b). Total Classes loaded: VisualVM counts the total number of classes loaded for any java application. c). Heap used: It shows how much of the heap is currently used by a java application. It is measured in MB. d). Threads: Athreadis a programs path of execution. Two types of threads are used: live thread and daemon thread. i. Live Thread also called used thread. User thread are threads created by programmer. ii. Daemon Threads are called service provider threads and run parallel to your code. When Java Virtual Machine finds no user threads all daemon thread terminate immediately. Some reusable Software Components are used to analyze the performance and make a comparison between them. A. Hibernate In 2001, Hibernate was developed by Gavin King. Hibernate is a tool for object-relational mapping. Object-relational mapping is a programming method for mapping Java objects to relational model where Java classes are mapped to tables [6] database. This is an open source persistent framework. There is a persistence framework powerful high performance and query service for Java application. Hibernate fills the gap and establish a connection between a Java application and a database. Hibernate uses the OO approach based on Java and binds known as POJO (plain old java objects) into a single object and table cards in a database java classes [14]. B. Spring Spring is a free and open source framework that offers many features for developers. It was jointly developed by Rod Johnson and Juergen Hoeller in June 2003 is also a base ORM framework. Spring Framework aims to make application development enterprise Java easier to use and promote good programming by allowing a POJO-based programming model. Important features are the Inversion of Control, AOP and Spring MVC [12]. Spring Framework allows us to manage the relationships between different parts of the project to loose coupling between modules. C. IBatis This is an open source Java-based framework for ORM mapping data. In 2001, IBatis developed by Clinton Begin. IBATIS is a persistence framework that allows the mapping between SQL databases and Java objects. Mappings are separated from the application logic by wrapping SQL statements in XML configuration files. IBATIS is a lightweight frame. IBatis mapping parameters and results between class properties and the columns of the database table [9]. D. EclipseLink The EclipseLink provides object relational persistence solution with additional features for developers. EclipseLink is also a focused framework for ORM progressed and provides support for relational databases. EclipseLink is a source object persistence and transformation of the open object framework. It provides execution capabilities that reduce development efforts and maintenance of an application. The software provides an extensible framework that allows developers to interact with many data services [13]. IV. RESULTS A. Simulation Environment Performance of Hibernate, Spring, EclipseLink and IBatis is measured using a java simulation tool. These four reusable software components perform basic SQL operations on the music database and the execution time is calculated and used to measure the way these mapping tools perform under various situations. The aim is to get the time from generation of SQL to querying music database and then getting back the data. The conditions were the same for all these components. The execution time of application is computed by applying select, insert database operations on these four reusable software components. For this purpose, a set of SQL queries is executed against music database. The performance of Hibernate, Spring, IBatis and EclipseLink is monitored under multi user environment because java supports multithreading environment. The tests were conducted in the following environment: Operating system: Microsoft Windows 7, Processor: Intel Core 2 Duo Processor, Memory: 2GB. To monitor a java application, the parameters that we have used are CPU Utilization, Classes loaded, No. of Threads executed and Heap used by reusable software component. The experimental results of these software components are represented using graphical charts. In this we have considered select and insert sql queries as two benchmarks. For the first Select Benchmark we have used these SQL queries are: TABLE 1. For Select Query These SQL select queries are executed at the backend in the database. When we run these queries it shows how much CPU is utilized, how many classes are loaded, how much heap is used and how much time it takes to execute the java application. According to the average graphs, it is clear that IBatis perform better for select query because its development time is less as compared to other components. IBatis is a data mapper i.e. it maps results sets to the object in java application while other components map the columns of database tables with the java classes. IBatis makes use of SQL which is database dependent. According to the graphs, IBatis has less average CPU utilization, less execution time and consumes less heap because stored procedures are used. A stored procedures is a group of SQL statements that created and stored on database. The stored procedures improved the heap usage and improve the performance of application. IBatis loaded less no. of classes because of lazy loading and another reason is multiple threads are executed simultaneously. The insignificant code is reduced to access a database. The results of select query benchmarks are shown in fig1, 2, 3, 4 and 5. Fig 1. Execution time Fig 2: Average Heap Used Fig 3: Total no. Classes loaded Fig 4: No. of Threads Executed Fig 5: CPU usage The insertion operation is regarded as the second benchmark. The insert operation is used to insert one or more rows in a database table. The first command of language data manipulation performed immediately after the creation of this table is the insertion expression. For the second Insert Benchmark we have used these SQL queries: TABLE 2. For Insert Query According to the average graphs, the Charts shown that IBatis performs better for insert benchmark. The average execution time is large, maximum heap is used because multiple records are inserted in to database tables. The only operation in which spring consumes more time is for the insert operation. The number of threads executed to run a java application in IBatis is less than hibernate because we don’t have to create the separate session for threads to insert objects into the database. The sessions in IBatis enhance the performance by reducing the number of times the application needs to access the data. In this case, larger number of classes are loaded in EclipseLink than IBatis but lesser than hibernate. EclipseLink consumes more CPU with respect to the other components. For every insert operations so much effort was necessary on querying, IBatis handles this query in a better way. The results of insert query benchmarks are shown in fig 6, 7, 8, 9 and 10. Fig 6: Execution time Fig 7: CPU utilization Fig 8: Heap Used. Fig 9: No. of Threads Executed. Fig 10. Number of classes loaded V. CONCLUSION This paper presents the comparative analysis of four reusable software components namely hibernate, spring, IBatis and EclipseLink. Reusability allows us to use existing software system rather than building them from scratch. Three performance benchmarks namely SELECT, INSERT and JOIN queries are used in order to measure the performance of reusable software components. These benchmarks were applied on these four reusable software components to analyze their performance and to make a comparison among them. The performance was analyzed using these performance metrics such as CPU utilization, heap Used, number of threads executed, execution time and number of classes loaded with the help of VisualVM. According to our results in SELECT and INSERT queries, IBatis showed outstanding results as compared to other reusable components because it uses less average CPU utilization because of multithreading. IBatis consumes less heap because caching in IBatis improves the performance by caching a ll the results in the mapping statement and reducing the unnecessary trips to the database. IBatis loaded less number of classes because IBatis is a light weight component. REFERENCES [1].

Albert Einstein :: essays research papers

Albert Einstein March 14 1879 - April 18 1955 Born Ulm, Germany. Died Princeton, USA. Albert Einstein was a very famous Scientist, he was mostly famous for his theory of Relativity. In 1894 Einstein's family moved to Milan and Einstein decided officially to relinquish his German citizenship in favor of Swiss. In 1895 Einstein failed an examination that would have allowed him to study for a diploma as an electrical engineer at Zurich. After attending secondary school at Aarau, Einstein returned (1896) to the Zurich Polytechnic, graduating (1900) as a secondary school teacher of mathematics and physics.   Ã‚  Ã‚  Ã‚  Ã‚  He worked at the patent office in Bern from 1902 to 1909 and while there he completed an astonishing range of theoretical physics publications, written in his spare time without the benefit of close contact with scientific literature or colleagues. Einstein earned a doctorate from the University of Zurich in 1905. In 1908 he became a lecturer at the University of Bern, the following year becoming professor of physics at the University of Zurich.   Ã‚  Ã‚  Ã‚  Ã‚  By 1909 Einstein was recognized as a leading scientific thinker. After holding chairs in Prague and Zurich he advanced (1914) to a prestigious post at the Kaiser-Wilhelm Gesellschaft in Berlin. From this time he never taught a university courses. Einstein remained on the staff at Berlin until 1933, from which time until his death he held a research position at the Institute for Advanced Study in Princeton.   Ã‚  Ã‚  Ã‚  Ã‚  In the first of three papers (1905) Einstein examined the phenomenon discovered by Max Planck, according to which electromagnetic energy seemed to be emitted from radiating objects in discrete quantities. The energy of these quanta was directly proportional to the frequency of the radiation. This seemed at odds with the classical electromagnetic theory, based on Maxwell's equations and the laws of thermodynamics which assumed that electromagnetic energy consisted of waves which could contain any small amount of energy. Einstein used Planck's quantum hypothesis to describe the electromagnetic radiation of light.   Ã‚  Ã‚  Ã‚  Ã‚  Einstein's second 1905 paper proposed what is today called the special theory of relativity. He based his new theory on a reinterpretation of the classical principle of relativity, namely that the laws of physics had to have the same form in any frame of reference. As a second fundamental hypothesis, Einstein assumed that the speed of light remained constant in all frames of reference, as required by Maxwell's theory.   Ã‚  Ã‚  Ã‚  Ã‚  Later in 1905 Einstein showed how mass and energy were equivalent. Einstein was not the first to propose all the components of special theory of relativity. His contribution is unifying important parts of classical mechanics and Maxwell's electrodynamics.

Love what you do and do what you love Essay

If you love what you do and do what you love; every man would find his life a joyful encounter and thus would agree to what Helen Hayes says, ‘if we rest, we rust’. Everyone has an ‘Eros’, a life-wish as they say, which fuels us to unveil the magnificent canvas of our dreams. If Mr. Ram Chandran, a top notch management adviser, whose daily planner inflects that he has appointment even when he is airborne with the person seated next to him, did even think that he needed rest, he would have to wait for a five good years! As his calendar entries are occupied till then. When asked for his stress and mental strength levels due to his busy schedule all that he advised to the young generation was that if you don’t have time to get bored, you pretty much don’t been need rest ! If we have a planned schedule for today and tomorrow, why should there ever be a need where in our minds say ‘Enough for the day, I am loosing it all, I think i need restâ €™. I wish to see myself teaching at one of the finest universities across the globe, and in order that i achieve what i have visualized, an equal amount of hard work and perseverance is required. If you are an ‘employee’ you take leaves to take ‘rest’, but when you are working for none but yourself you are the ‘employer’ and employees and self- believers believe in one common inner will which says, ‘if it takes madness to reach, where you want , be mad!’ Our mind is considered to be one of the most dynamic substances existing today! To let it rest would be to subject it to the vulnerabilities, which not only will affect our professional lives, but also our inner strengths and abilities! Things have their value, when they are best put to use! Things have been their value, when they are constantly being demanded for! And it holds true even for one body. Then be it for the attainment of luxurious professional lives or satisfying one’s soul, a constant up gradation, an undeniable change, a relentless dynamism is critical  I entirely agree with this statement: â€Å"If you rest, you rust.† In fact, I had seen my friend who had failed to the test by his sluggish. Also, I had been seen two of South Korea Presidents: Mr. Noh and Mr Park. My friend was top 10 student at Korean High School. He and I had competed each other in Academics since I was top 10 as well. He always, however, had surpassed me by two or three place until he indulge himself in indolence. I saw depravity of my friend; he was too confident by himself and did not study as hard as  before he did. He thought he can still be top 10 without study hard. He always played game, met girlfriend, and smoked even during the final period. I felt as if a cloud settled over him. After final, a teacher gave the students their transcript. He failed. I got top 10. Another example, there were two South Korea Presidents who had succeed and failed. Mr. Park, at first, who was the President in 1970 was army in South Korea, and he got power by a military coup. He, at that time, was condemned by nation. However, Mr. Park did so many good things during his period. Especially, his project, known as â€Å"New Region Project†, was praised by all nation. This project had brought up South Korea’s economy. According to â€Å"Jo Sun Il Bo†, which is the famous newspaper in South Korea at that time, South Korea’s GDP, Gross Donation Products, was risen from 7,000 dollars to 9600 dollars. All these things could have happened by his assiduous work. In contrast, Mr. Noh who was President in 2002 to 2007 was took criticism by his indolence. Simply, he did not do anything during his period. He even went to movie theater to watch movie with his wife. The most worst thing is that he said he want to abdicate and be a farmer without any burden although he actually did nothing. For these reasons, the nation confidence degree of Mr. Noh had been falling by 22% in 2007. Once people be indolence, then they do not want to do anything, and this sloth make them to be rust. My friend and Mr. Noh had corrupted by their idleness. If you rest, you must be rust..

Advantage and Disadvantage of Agriculture

Role and impact of biotechnology in modern agriculture. Biotechnology offers prospects in addressing problems concerned with agricultural productivity and environmental safety. In order to cope up with the ever increasing population of the current world, biotechnological intervention to supplement conventional plant breeding efforts is indispensable. Some of the issues that can be addressed using biotechnological techniques are crop production of superior quality, mass production of uniform planting materials, compensate land shortages and genetic improvement of the plant. pic][pic][pic][pic]A few of the advantages perceived in the use of biotechnology in agriculture are rapid multiplication of plant species, breeding of resistant varieties, diagnosis and control of disease in crop and livestock, utilization of crop residues and animal waste. Some of the disadvantages are high cost of research and development, endangering biodiversity, genetic erosion and lack of access for poor farm ers to use new varieties. Thus, in introducing biotechnology in agriculture, it is vitally important to study and assess the overall circumstances, such as cost effectiveness and impact on environment.Agriculture is of primary importance in the National Development Program. Biotechnology, as a new frontier in agricultural sciences, has opened new avenues for the solution of agricultural problems. The application of biotechnology in agriculture offers many possibilities for filling the gaps found in conventional research methods and is therefore, not intended to replace all conventional methods, but to provide a more reliable approach in achieving economic gains.Many new tools are now available, particularly from research in the areas of molecular biology, genetic engineering, and cell and tissue culture as well as from intensive application of microbial technology. The initiation of research and development in agricultural biotechnology dates back to the late 1970s when tissue cultu re techniques such as embryo culture and anther culture were first introduced as means to produce virus-free crops and improve crop quality in the production of vegetables, flowers and fruit trees.Virus free potatoes, garlic and strawberry are already in the market for farmers. Production of high yielding rice varieties are good examples of success achieved by the use of anther culture techniques in rice varietal improvement. Read more in Engineering  «Ã‚  Difference Between Diesel and Gasoline Engines Ohm’s Law  Ã‚ » Various technical barriers that have to be overcome are the establishment of transformation systems in agriculturally important food crops and regeneration of fertile plants from transgenic plants.In the areas of gene manipulation and transformation, well trained scientists are needed. Most of the laboratories involved in plant biotechnology carry out tissue culture research, mainly the development of media protocols for micropropagation. Over the years, met hodologies for disease elimination by meristem culture and / or micropropagation and in vitrogermplasm conservation have been developed for fruit crops (banana, strawberry and pineapple), root and tuber crops (potato and sweet potato), ornamentals, cut flowers (orchids, lilies) and a few medicinal plants.Research is also underway to perfect micropropagation technology for tree species which are endemic. Tea, potato and banana are being produced on a commercial scale using established micropropagation techniques. A near commercial line of sugarcane, resistant to smut, has been produced through in vitromutagenesis. Molecular biology approaches for crop improvement have been conducted with little success. pic]Evidently, all the countries have been able to recognize their objectives and goals more clearly in the use of biotechnology in agriculture and have initiated appropriate policies to meet some of the challenges posed by critical areas in directing future development. It is hoped t hat biotechnological approaches in agriculture will provide ways and means of utilizing its full potential to benefit the community.Read more: http://scienceray. com/technology/engineering/biotechnology-in-modern-agriculture/#ixzz12cOlCxP2
