Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Background: Businesses are traditionally valued with the so called Discounted Cash Flow-model. When valuing newly-started businesses, surrounded by high uncertainty, and whose capital mostly consists of unrealized business opportunities, the Discounted Cash Flow-model needs to be complemented if the total value of the business is to be captured. A valuation with the help of real options is capable of valuing these unrealized opportunities, which often exist in newly-started businesses. The unrealized opportunities are to be found in the business plan of the business, why this needs to be valued to capture the total value of a newly-started business. Purpose: To demonstrate what the use of real options can result in when valuing businesses.

Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.

This paper addresses how political parties make decisions. Parties often have to choose between conflicting objectives such as influence on policy, control of the government, and support among the voters. This paper examines the behavior of the two Swedish parties on one of their particular policy positions: Swedish withdrawal from the EU. The aim is to describe why the Left Party (Vänsterpartiet) and the Green Party (Miljöpartiet) retain thisspecific policy position when it on one hand seems damaging to their chances of getting into government, and on the other seems to be an unrealistic policy to realize. I undertake a twocase study of the two Swedish parties, which I assume to represent a population of Nordic parties critical to the EU.

Konsultverksamheter har idag en stor mängd system och leverantörer att välja mellan vid val av att bli återförsäljare till ett nytt system. Denna mängd av system kan vid vissa tillfällen ställa till osäkerhet i form av vilket system som passar bäst in i verksamhetens portfolio. Genom en effektiv utvärdering kan dock detta avhjälpas och det system som passar bäst för verksamhet väljas. Uppsatsen bygger på en kvalitativ litteraturstudie där också en intervju utförts. Vidare har de teoretiska utgångspunkterna hämtats utifrån modeller såsom Standardsystem i Verksamheter och Välja och Förvalta Standardsystem. Dessa modeller ligger sedermera till grund för den modell som presenteras i uppsatsen och förenklar konsultverksamheternas problematik med att fatta ett genomarbetat val av system till sin portfolio..

The purpose of this project was to create a system which can handle issues, with other words an issue tracking system. The system must create issues, assign issues to a specific user and list all issues for each user. On top of that, each issue should have a log where users can log whatever they want.My part of this project was to implement a client which can fulfill this basic criteria (and a bit more if possible), and communicate with the server which has procedures to be executed by the client.This system is based on Android and has it purpose to be used by mobile devices which support Android. ?Ichnaea? as the system is called, is meant to be used by companies to have human interaction through the network..
