Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

The purpose of this thesis is to examine whether the concept of permanent establishment, as defined in Article 5 of the OECD Model Tax Convention on Income and Capital, is applicable to electronic commerce and if so whether the current definition is able to appropriately deal with the challenges of electronic commerce.In 2003, the OECD added a new section to the Commentary on the Model Tax Convention on Article 5. The new section is a clarification on the application of the permanent establishment definition in electronic commerce.The current definition of permanent establishment in the Model Tax Convention relies on the physical presence of a foreign corporation as the threshold for source taxation. While the current definition, prima facie, might be applicable on electronic commerce, the highly mobile nature of electronic commerce might affect the current revenue distribution equilibrium between states..

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.

This is a study on the electronic reference work of some Swedish university and university college libraries. The purpose of the study has been to find out how the service works at the different libraries, to study the electronic reference interview and to find what is important when you start a new electronic reference service in the light of Brenda Dervin's sense-making theory study. Furthermore, we examine the aims of the electronic services offered and the differences between electronic and traditional reference interviews. In the background to the study we place electronic reference services in a context by describing the role of information technology and electronic mail in the libraries. The electronic reference interview is studied with the help of literature on the traditional reference interview.

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

AbstractThe dependency of fossil fuels in the transport sector causes large emissions of carbondioxide. This problem can we reduce by using vehicle gas from digested solid manure and leftover of pasture. I have studied the potential for this in the county of Västernorrland. Thepurpose is to investigate how much vehicle gas that can be extracted.One central, large scale digestion and upgrade plant should be placed in Härnösand. Theamount of pasture and manure that is economical and practical available is enough to produce2,7-3,5 millions Nm3 vehicle gas.

The transition from paper to electronic journals in induces a major change in academic libraries. The library must focus on customising the service to meet user needs in order to compete with other actors on the market. This situation entails the need for a marketing and management approach in library organisations. Linda Ashcroft has in previous research focused on marketing of electronic journals. She has stated the importance of simplifying the user environment of electronic journals and the importance of regaining control over electronic journals from publishers and vendors.

The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.

This report covers the conceptual design of a new one person hybrid vehicle that is to be fast and convenient to drive on the roads. The vehicle is most of all supposed to be used as a commute vehicle but can also be used at other occasions as well.During the work with this project the group has focused on three larger areas, the outer design (body), wheel chassis and an ergonomically designed interior. The group was not able to just create these parts in 3D to get a trustworthy vehicle, hence number of other components and details were also created to get a better entirety.The outer design starts with idea generation and sketches and ends with a 3D model which is rendered to show how the final product is going to look. The design of the body has been going on during the entire work process due to new ideas and improvements that seemed interesting and had to be changed.The wheel chassis also started with idea generation, research and sketches. It ended up with a simulated 3D model which later on was mounted on the vehicle body to show how the vehicle is going to perform during usage.

Communication between parties in an important process in their relationship can be based on a contract. This communication can for exemple be composed by a handwritten contract or an electronic contract. Contract law makes no difference between these two forms. to create more favourable requirements for commencing a contract or an ongoing contract there are possibilities to use standard agreements. Therefore a contract can be based on the will of the parties or on a standard agreement.An electronic signature shall secure that electronic transferred information has not been altered and also to identify the sender of the information.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

This thesis seeks to investigate how an agreed written form requirement is met in an electronic environment. Swedish Contract law is applied since Sweden lack specific regulation for electronically closed agreements. Since contractual freedom prevails in Swedish law, it is up to the parties themselves to decide if the formal requirements to be applied.In order to assess whether the written requirement is fulfilled in the electronic environment, a purpose-oriented analysis should be made. When the purpose of why a written form requirement applies has been clarified, the analysis continues to assess whether the objective can be achieved with the modern form of communication. The method is called functional equivalence and means that when an electronic media fulfill the same functions as the paper medium so will the electronic medium as a starting point to give the same legal effect as if it were the case of a written paper document.

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another.

As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.
