This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..

A project exploring the boundaries between 2D and 3D. What is surface and what is substance? A countinuation of previous projects where I?ve examined the journey from two dimensional paper to three dimensonal objects. This project deals with the journey from three dimensonality back into a flat two dimensional surface, and the question if something can be both 2D and 3D at the same time. I decided not to center the project around a specific item, but rather let the project itself be in focus.

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

Purpose There are almost infinite numbers of ways to build dairy farms in Sweden. When building a new free stall barn you have the possibility to affect both working environment and animal welfare for many years to come. The construction costs are influenced by which type of barn that is built and what functions it contains, for example one can predict that automatic milking systems are more expensive to integrate than milking parlours. But what is the real cost of today for the construction of free stall barns with milking centres and how is it affected by construction methods and functions? Is the labour time influenced by the building costs? These are some of the questions this report will try to answer.

The aim with this study is to achieve an increased understanding and knowledge about terrorist groups. The factors that the study come to be focused around is the groups' objectives, their organization, which enemies they have and with which means that they use for there terrorism. In order to respond to this aim the four different terrorist groups, Colombian revolutionary armed forces (FARC), Baskien - our native country and our freedom (ETA), red Army fraction (RAF) and al Qaida is studied.To achieve the aim of this study the methods qualitative text analysis and comparative method is being used. It is designed also within the framework of this study a categorization model that is used as method in order to do a division of the studied groups based on their objective, enemies, organization and means. The model is also constructed to be used in order to analyze others terrorist groups than these current groups.The result of the study is presented in the categorization model on page 32 in the essay..

Title: Dormant companies ? Taxation of closely held companiesProblem: Many companies are facing a business transfer and fall within a smaller company with a few owners and therefore that tax jurisdiction is current. They risk facing high taxes but it can be avoid by setting the company in an inactive status for five years.Purpose: The purpose is to describe the inactive company rules and the verdict from the Swedish Supreme Administrative Court. Also to investigate how this verdict will affect company sellers.Method: Based on a case study and by analyzing the Swedish Law conclusions has been determinate.Result: A dormant company must be inactive for five years, and then the company can benefit from a different taxation. The owner and it´s relatives can´t be active in the company during this five year period.

During the last decade, there has been an increase in the use of technology-based self-services within the retail sector. The increase is particularly noticeable within the grocery market. The reason behind the increased use of these systems is partially due to the fact that companies within highly competitive retail markets continually look for ways of decreasing costs while upholding efficiency. The problem is that it is difficult to understand the true economical implications of investments relating to these machines. The purpose of this study is to investigate and contribute with new insights regarding the cost-structures of the stationary self-checkout systems and traditional cashier desks, within the retail grocery market.

This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge. In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change. The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes. The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.

AbstractSierra Leone is a very poor country in Africa. Botswana is another country, that has a similar history and the same deposit; diamonds. Botswana has reached economic growth and democracy and Sierra Leone has not.The purpose with this study is to explain why Botswana is more democratic and has reached a better result economic than Sierra Leone.The questions in this study are:What explains the democratic and the economic results in Sierra Leone and Botswana?* Dahl?s institutions that furthers a polyarchy?* Gunnarsson?s and Rojas? institutional explanations?* Diamond?s and Morlino?s ?rule of law??* Other explanations or a combination of the above-mentioned explanations?The method that has been used in this study is a comparative case study with a qualitative contents analysis. The result is that it?s hard to say that one explanation is the right one.

AbstractAimThe aim is that by using the curriculumcodes, analyze and compare four curriculums in physical education. The study begins in the elementary school introduction in 1962, and then makes three more strikes in 1980, 1994 and 2011.The questions that are addressed in this paper are,Which expression of competence code can be found in the different curricular?What are the expressions for performance code can be found in the different curricula?Is there any change regarding which code teachers use when they assess the students?Method  As a basis, the four curricula Lgr 62 Lgr 80, Lpo 94 and Lgr 11 in physical education are used. These four curriculums are studied and compared for similarities and changes in the assessment uses comparative content analysis. A number of publications in the curriculum codes are used in the analysis of the curriculum.

Studien syftar till att undersöka förekomsten av hållbar utveckling i Lpo94, då vi utifrån våra erfarenheter inom skolan inte har sett någon undervisning för hållbar utveckling bedrivas. Ytterligare en anledning till att undersöka förekomsten är då Sverige ingår i flera internationella överenskommelser där det framkommer att undervisning för hållbar utveckling ska vara prioriterat. Då en ny läroplan, Lgr11, träder i kraft 1juli 2011 undersöktes även förekomsten av hållbar utveckling däri, då studien syftar till att undersöka huruvida det skett förändringar till fördel för undervisning för hållbar utveckling i Lgr11 i förhållande till Lpo94. Vid analysen av läroplanerna användes en metodtriangulering, i form av innehållsanalyser, textanalyser samt komparativa analyser. Inför analyserna fastställdes några kriterier som utgick från innebörden av hållbar utveckling, vilka hela studien sedan kom att bygga på.

Denmark, Germany and Sweden are along with 24 other countries members of the European Union. Being part of the European Union also means being part of a European market. Within the union barriers for trade has been abolished in order to create more open market. This open market has also contributed towards a more globalized market for dairy products. What used to be a domestic market has become globalised with increasing trade among the members.
