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..

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

This thesis studies private equity firms' implementation of management control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).

This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.

In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Bachelor thesis, Controller, Program of Master of Science in Business and Economics, School of Business and Economics at Linneaus University in Växjö, Sweden, Course Code: 2FE13E:3, Spring 2012 Authors: Jacob Cedergren, Adam Pettersson, Hampus SkelterwijkSupervisor: Anders JerrelingTitle: The ERP-systems impact of the management control - a case study of VIDA AB Original Title: Affärssystemens påverkan på ekonomistyrningen - en fallstudie på VIDA ABBackground: New technology has given businesses new opportunities to use and store information and the current information systems has changed the way of working in more or less all sectors and operations. ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.

This study has examined if importation of waste for energy recovery can reduce the climate impacts of Waste Management Systems. Using Systems Analysis this study will try to examine the complex waste systems in a systematical and strictly logical way to see how these systems interact and affect each other. Specifically examining the climate impact of waste management systems in England. The traditional way of handling waste in England is through Landfills. Land filling leads to emissions of the greenhouse gas Methane. The EU has put in place a landfill directive that is supposed to lead the member states away from land filling as a method of waste management. Today in Sweden there is a competition for the waste available for incineration. The worsening economical situation together with less product packaging and an increase in source separation leads to a lack of waste available for incineration.

This paper describes how files and information can be shared in organisations and workplaces. We studied and compared the traditional file sharing in Microsoft Active Directory and the Social file sharing that comes with Microsoft SharePoint Sites. We used qualitative studies based on interviews with system administrators, management and by our own observations to acquire the necessary data. Using independent research, we were able to analyze the data and show the general difference between the traditional and the social file sharing systems. Social file sharing enables the user to easily store and share files in a flexible online environment.

The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.

When constructing a new house many questions appear, from architecture to decisions regarding installations. Sweden is situated in a cold part of the planet and questions regarding which heating system to install face everyone who decides to build a new house. This thesis describes a construction solution of a villa in Kiruna. The extended essay analyzes which heating system is most suitable for the construction. The options are geothermal, district and pellet heating systems.
