Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf.Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar.

Arbetets syfte är att undersöka hur högstadieelever för matematiskt resonemang. De frågeställningar som studien inriktas på är vilka lösningsstrategier elever väljer då de resonerar matematiskt såväl som vad  det finns för skillnader och likheter mellan de yngre elevernas lösningar och de äldre elevernas lösningar.Undersökningen genomfördes i två klasser, den ena i årskurs 8 och den andra i årskurs 9, på en grundskola. Eleverna fick lösa uppgifter, vilka uppmanade dem att föra matematiskt resonemang, individuellt. Resultatet av studien visar att majoriteten av undersökta elever har valt att resonera deduktivt. Jämförelsen av elevers lösningar i två årskurser visar att årskurs 9 elevers resonemangsföring präglas av större förtrogenhet med den algebraiska demonstrationen.

Abstract ? ?Costs to consider in connection with the implementation of a new ERP system?Date: January 8th 2013Level: Master thesis in business administration, 15 ECTSInstitution: School of Sustainable development of society and technology, Mälardalen UniversityAuthors: Sanna Hellblom-BjörnTitle: Costs to consider in connection with the implementation of a new ERP systemTutor: Cecilia LindhKeywords: ERP-system, business system, implementation, implementation costsResearch question: What costs and issues should companies take into account in order to  establish a realistic budget in connection with the implementation of a new ERP system, and increase the chances for a successful implementation?Purpose: The purpose of the paper is to investigate the hidden costs that may arise in connection with the implementation of an ERP system that companies should take into account in order to establish a realistic budget. The paper will also examine how companies can reduce their costs and affect the outcome of the implementation. It should be investigated by means of interviews, reports and articles.Method: In order to answer the question in the paper secondary data is collected in the form of articles, books and reports. Primary data was collected through interviewing a company that has implemented a new business system, a company that performs implementations and a Senior manager of ERP Services.

Syftet med detta arbete är att jämföra International Baccalaureate Diploma Programme (IB), med svenska SP och NV program. Detta görs genom att besvara frågan hur innehållen i matematikkurserna på IB programmet skiljer sig från matematikkurser som ges i de svenska programmen. Inte enbart innehållet i kurserna jämförs utan även timplanen granskas för att undersöka om arbetsbördan i programmen skiljer sig åt. Den lättaste matematikkursen som undervisas i IB programmet, Mathematical Studies är mest lik de svenska Matematik A-C kurserna. Den andra IB kursen, Mathematical Methods täcker framförallt Matematik A-E kurserna medan den tredje kursen, Mathematics Higher Level stämmer bäst överens med Matematik kurserna A-F och Matematik-diskret.

This paper seeks to discern the political factors that determine the results of negotiations in international cooperation. On the one hand, it makes a contribution to the broader theoretical debate on international regimes by combining regime theory and theories on globalisation into an integrated framework for the analysis of international policy results, or in this case treaties (theoretical objective). More generally, globalisation theory will help us understand why it has become important to initiate international cooperation, and regime theory to elucidate how these international cooperations emerge. To many observers, it is the large transnational corporations of the rich North, which have done best out of free trade. Through the huge influence they wield over governments at the WTO (World Trade Organisation), these corporations have won the freedom to move around the globe without restriction, making use of cheap labour, and locating wherever they can best tap into the largest and most lucrative markets.

Syftet var att studera matematikundervisningens utveckling genom att beskriva styrdokumentens, läroplanernas och kursplanernas påverkan på undervisningen. Bakgrunden till detta examensarbete är det faktum att många elever uppfattar skolmatematiken som komplicerad och ointressant och att de inte når de uppsatta målen. Metoden som användes var en litteraturgenomgång där matematikundervisningens utveckling studerades. Genom att även utföra en kvalitativ intervjuundersökning kunde fem yrkeserfarna pedagoger beskriva hur de uppfattar denna utveckling och hur det visar sig i deras matematikundervisning. Studien visar att i takt med att samhället utvecklas och förändras utvecklas också styrdokumenten.

The basic principle of the integrated school according to the Salamanca Declaration is that all children, whenever possible, should be taught together, regardless of any difficulties or diversity. It has been shown that students with neuropsychiatric disorders are having much more difficulties to achieve the targets than the average student. Pupils with neuropsychiatric syndrome will always be present in school and we who are working in the business must be better at learning to adapt to them so that they too can achieve proficiency in school.Mathematics is perhaps the topic that Swedish students generally have most problems with,and it will not obviously be easier if you have some form of neuropsychiatric disability.In our future role as special education teachers, we will mentor and support other teachers in the complex educational environment that exists today. The aim that has been built up is thus partly to explore how mathematics teachers work with included students with neuropsychiatric disorders, as well as how teachers wishing to become supervised by specialeducation teachers in mathematics. The study is conducted from a sociocultural perspective.A sociocultural perspective on learning means that all people are learning all the time in social settings.

The first vampire film I ever saw was Interview with a vampire. ?I haven?t been human for two hundred years?, opened up not only the film, but a whole new world I knew nothing about. The world, as it were, opened its doors to me again after I had seen the film adaption of Stephenie Meyers Twilight. I decided to write down a few thoughts, capture my frame of mind, and these paragraphs then turned into a text: ?I tankarnas skal?.              When I did research for this essay I discovered that my text held certain similarities with the modern vampire novel.

The main purpose of this thesis is to discuss what exile writing is and who can be seen as an exile writer. If the word ?exile? is related to forced dislocation, like Paul Tabori and Sopia A. McClennen describes it, who can be viewed as an exile writer? Is Anders Olsson?s definition of an exile writer acceptable or not? Could the The Escape, a future story about exiled Northern Europeans in Myanmar, be classified as exile literature?Another purpose with this text is to describe how a story about exile can be made realistic and tangible to a reader who has not experienced exile.

The aim of this study was to investigate, illuminate and discuss teacher?s and multilingual student?s view on the connection between their mother tongue and their learning of other languages. This qualitative study is based on interviews with eight students in the 8th grade and two language-teachers from the same school, as well as ethnographic observations during English and Swedish lessons. With the help of some relevant theories, the empirical study is compared, analyzed and interpreted. The results show that the theories and informant?s view on the connection between the mother tongue and other languages are similar, which is that the mother tongue must be fully established before a new language can be taken in..

The purpose of this thesis work is to create a prototype for an augmented reality application that isaimed to support service technician when performing service and maintenance of machines andengines. The prototype will be used for investigating what technical limitations there is and toestablish basic usability for the user interface. The method that is used is user studies and analysis toevaluate use cases and user stories. An iterative work process is then applied for design and theprototype is continuously user tested.The resulting prototype uses a Samsung Galaxy Tab 2 running on Android operating system. Theframework used for augmented reality is NyARToolkit which handles marker recognition andconnections to Android.

The purpose with this study is to gain understanding about student´s view of mathematical education, in the later years of nine-year compulsory school, and the motivation factors that can be identified when student´s gives opportunity to express their own thoughts due to the mathematical education. From experiences we have gained during the practical part of our teachers education we got the impression that student´s think that the mathematical education is boring and uninteresting. Through qualitative methods such as survey and discussions in focus group we have analyzed student´s views of mathematical education and pointed out witch motivation factors that are expressed when student´s gives opportunity to influence over their own education. The results are shown from the answers and comments that student´s gave, during the survey and focus group, and is divided into two main parts, both with focus on motivation ?Mathematics and motivation? and ?Student´s influence and motivation? and also a summery part ?Motivated for mathematical education when the student is given influence over the education?. The study showed that student´s wants to have more difference in the work methods that are used in their mathematical education such as problem solving, games, more work in groups and pairs and more use of IT. In conclusion the study also gives suggestions to other studies that can be made in the same genre as this study in the way that IT can be used in mathematical education and how student´s interest can be used in the education to gain more motivated student´s..

This thesis examines some special education teachers with experiences of childrendiagnosed with dyscalculia. Problems with mathematics at school may occur to allchildren in all schools. It is therefore important that the teacher knows the variousdisabilities that teachers may encounter. The study is based on four randomlyselected special education teachers, all-working at schools that are related to amedium-sized Swedish town. This work will immerse in the knowledge ofdyscalculia among four special education teachers.The interviews revealed that all special education teachers felt that dyscalculiainvolves specific difficulties in mathematics, their views on dyscalculia is consistentwith current research.

Mankind has always been communicating, it is almost impossible to not communicate. The communication tree has grown a new branch, the environmental communication branch, and an ISO standard, the ISO 14 063 Environmental communication- guidelines and examples was issued October 2006. The purpose of this thesis is commissioned by the managing director of NQA Nordic AB in order to examine and analyse how organisations communicate environmental issues today, and how big the need for ISO 14 063 actually is, and further more if there are needs and wishes to make ISO 14 063 a certifiable standard. The main conclusion is that the there is a need for the standard, but it is difficult to say in which form since the knowledge about the standard is far to low among the organisations examined in this thesis. Clarity and transparency as ISO 14 063 promotes are important ingredients in organisations? environmental work, so sure a standard for environmental communication can help improve environmental performance, for example through opening up for two-way communication and from that on take part of the stakeholders? opinions.This study is based on a literature study and a questionnaire survey where 70 organisations (in this case authorities, corporations and non-governmental organisations) randomly chosen from the seven criteria, which ISO 14 001 defines as the environment: land, water, air, flora, fauna, natural resources and man and his collaboration with those.
