Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar cells and solar thermal collectors. Solar cells convert solar energy in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of Sweden's foremost venues.

The ongoing construction of Kristianstad is a trade mall in the city center, the City Hall and the railway station neighborhood is rebuilding, new residential projects are planned and "The healthy garden", "Accessibility for everyone" and "ERA-farms" are also current. Kristianstad has always a sustainable way of thinking in the background during the development and they are trying to meet all three perspective of sustainability: economical, ecological and social. The municipality seeks knowledge both by sharing their own and takes part in other municipalities in the development process..

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

It often occurs that the spirit regarding the future as a conservator is rather pessimistic. Howcome that there are so few employed conservators, when the need for conservation obviouslyis big? What kind of changes is needed for a better status regarding the conservation?This thesis concerns the development of the field of conservation in Sweden. What havehappened, what will happen and, particularly, what should happen? The information wasgathered from literature studies and interviews during the spring of 2010.

The purpose of my study was to examine a competence-development in care of older people in which some of the personnel have been ?spjutspetsar?. More specifically my aim was to investigate how the personnel managed to supervise others in the organization. My main research questions were: How do the care-managers and the care-workers persecute their functions as ?spjutspetsar?? What form has the internal meeting between the competence-development and the organization ideology taken? What possibilities and obstacles have the care-managers and care-workers been confronted? In my study my research method is based on eight qualitative interviews.

Daily citizens are informed by the media about the environment and the climate changes. The schools purpose is to educate students according to events that are of current interest and take place in present time. According to Swedish curriculum, Lpf94, all Swedish education should include and discuss the problems surrounding durable development. The purpose of the study is to se how the textbooks in History, Social studies and Geography and their contents meet the demands of the curriculum. The study shows that only the textbooks in geography meets the demands that the curriculums have on durable development.

In the end of the 80´s the area of system development moved into a new era. As a consequence many new methods and development models emerged which in many cases resulted in problems when choosing system development models and methods. As a result of these problems the today standardized modeling language UML (Unified Modeling Language) was created. UML is tailored to support many different types of projects. This is possible because of UML?s capacity to be adjusted and adapted to a specific company environment.The purpose of this bachelor thesis is to investigate how and why companies use UML and what experiences and opinions those who use UML have of using UML in practice.

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

This report is about an investigation which has been done as an assignment in aninternational company. An Intranet has been implemented in parts of this company, andprimarily there is a local group of people in the company which is responsible for thelocal Intranet as an informationsystem. This local group of people is also responsiblefor further development of the use of Intranet as an informationssystem in the localorganisation. To create a starting-point for this development, I have done aninvestigation that deals with:· acceptance of Intranet as informationssystem among members of the industrialmanagement.- what factors affect acceptance of Intranet in a negative way- what factors affect acceptance of Intranet in a positive way· rules by which further development of Intranet is supposed to be based on· existing and needed Intranet-applications..

Distributed system development is a common occurrence in today?s technological and global world. Because the consequences of its geographically distributed nature it creates barriers between people that affects their communication and collaboration efforts in the distributed context. Despite a lot of technological breakthroughs over the last decades and the occurrence of video-conference applications and other tools for communication and collaboration, cultural and geographical issues have so far not yet been completely resolved. In this study I have made a literature study over distributed system development to form a set of central factors that affects the distributed development process.
