Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

The aim of this bachelor thesis is to examine the current situation as regarding the political equality in Iran. The method of this reaserch is based on a single-case studie wich grounds in secondary sources. The analysis of this paper is based on fields that concern political equality which in this study will focus on the right to vote, candidacies in the parliament election 2004 and the presidential election 2005. A democracy theory by Jack Lively is used to analyze the political equality in Iran´s political system.The Iranian regim is strongly criticized by the goverments in the Western world and NGO´s for the situation of the democracy and the human rights in the country. Despite the criticism, Iran still continues in the same political direction, although the democracy has gained a stronger role in the political sphere.

I denna studie undersöktes designöverväganden för ett VR-system som ska stödja en arkitektonisk designprocess. Dagens användning av VR-system inom arkitektur är inte särskilt utbredd men anses vara ett stort framtida användningsområde för VR-teknik. Större delen av den forsk-ning som bedrivs inom VR-området fokuserar på tekniken i sig. VR-system skapade i demonstrationssyfte används till att undersöka fenomen som avståndsbedömning och navigeringsförmåga i virtuella världar. Denna forskning är viktig, men är inte tillräcklig för att ge vägledning i hur man bör designa ett VR-system som ska stödja en arkitektonisk process.

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

Military dogs in Sweden spend their first 18 months after weaning with a foster owner that has volunteered to care for its upbringing. The foster owner is advised by a consultant and offered three opportunities to train the dog together with other foster owners. There is a positive correlation between the number of attended training opportunities with the consultant, or other professional dog trainers, and the results of the dog in the temperament test at the end of the 18 months. The test results are in turn positively correlated with the likelihood of the dog to enter service. This thesis aims to investigate why the number of training opportunities is important for the dog?s chance to enter service by identifying foster owner factors that influence the success of the dog and which temperament test items the factors have the strongest impact on.

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

Organisationer står inför ständiga förändringar och det medför att organisationers IT-system behöver anpassas därefter. För att besvara dessa förändringar investeras det i nya IT-system. Dock prioriteras oftast inte hantering av de föregående systemen, så som systemavveckling. Systemavveckling behandlas ytterst lite i befintlig litteratur, till exempel hur en systematisk avvecklingsprocess skulle kunna genomföras. Utifrån detta utformades uppsatsens syfte att belysa ämnet systemavveckling och kartlägga centrala begrepp. För att uppnå syftet har två fallstudier genomförts samt en genomgång av befintlig litteratur.

Den här studien avser att undersöka i vilken utsträckning befintliga riktlinjer för datorstött samarbete är tillämpbara för asynkrona, geografiskt distribuerade system i syfte om att minska det socio-tekniska glappet. Det är ett glapp mellan vad användare efterfrågar socialt och vad som är tekniskt möjligt att stödja, där medvetenhet om andra användare är en central utmaning som påvisar ett glapp. Som praktiskt fall studeras Intercopy.net som är ett system för dokumenthantering via Internet. Resultaten visar att det verkar finnas få riktlinjer specifikt avsedda för asynkrona, distribuerade system och de som avser datorstött samarbete generellt kan vara svåra att tillämpa. Riktlinjer för enskilda användare och för datorstött samarbete kan därför med fördel kombineras vid utveckling och utvärdering av datorstött samarbete för att öka användbarheten på individ- och gruppnivå.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

The purpose of this thesis is to explain one aspect of how and why the development in the third world is lagging behind. The precondition is that development through an agricultural revolution is necessary and that all countries benefit from trading. But these two conditions are not met today. By using the urban-bias and the world system theory I have analysed how the situation appears to be according to the precondition. It appears that both the urban-bias and the world system theory are essential to understand how and why the situation in third world still has not reached the same development phase as most other countries.

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.

In this essay we discuss how the decentralisation of the Swedish school system affects the concept of ?equal opportunity school?. We investigate the development from both a historical and contemporary perspective, in order to identify changes over time. The central question of the essay is how the decentralisation of the school system affects the teacher?s perspective and experiences of the government?s framework about ?equal opportunity school?? The analysis is based on four qualitative, semi structured, direct interviews with respondents both active in municipal schools situated in the Malmö council and with more than thirty years of experience in their profession. Our analysis of the interviews show that both respondents experience the overall situation in the schools has deteriorated from an equal opportunity aspect since the decentralisation of the school system.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.
