Ström- och temperaturkontroll
Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.
?Ärligt talat så har det [tradingen] blivit en skitaffär? : En fallstudie av HQ Bank
The global financial crisis hit hard on banking operations worldwide and the sector fell under considerable scrutiny, with particular criticism directed against the banks' own trading practices. A bank owned by the Swedish financial corporation HQ seemed to go without serious financial damage duringthe crisis.In 2008 Finansinspektionen began a review of HQ's activities and a number of shortcomings were identified. Among other things, HQ's risk management was questioned by Finansinspektionen and further how this potentially affected the valuation of complex financial products.In our paper we have chosen to highlight both national and international laws and guidelines that HQ used for their operations and study if HQ followed those laws and guidelines. We also want topresent the theoretical model used by HQ for the valuation of its European options and how HQ calculated their capital requirements ratio. Our purpose is to show how the valuation affected the capitalrequirement ratio and whether HQ followed the necessary laws and guidelines for the valuation of complex financial products.We have chosen to carry out a case study from a deductive approach.

Research method: The study was realized with the help of twelve qualitative interviews. Result: The elements of importance when creating a successful negotiation with regard to building long-term relationships were mainly elements of co-operation and to some extent elements of competition.
OPAC i moderna kläder ? en kvalitativ studie om olika generationers informationssökningsvanor och förväntningar på informationsåtervinningssystem
The purpose of this bachelor thesis is to find out how information seeking habits and experiences of people in different generations affects their expectations on information retrieval systems like OPAC. Two OPACs are used, one web-OPAC and one mobile-OPAC. The following questions are asked: how can theories about information seeking behaviors explain why and in which way one seeks information? In which way does information seeking behaviors and habits affect the experience of OPAC? Which differences and/or similarities can be found between the web-OPAC and the mobile-OPAC? How does generational aspects affect experiences and preferences in an information seeking context? The theoretical framework of the thesis is information retrieval with several models about information-seeking/searching needs and behaviors. The empirical data contains interviews with nine people in different generations and protocols about two different OPACs.
Realtidsoperativsystem på mätinstrument
Emwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon
In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.
Effekter av tidiga reflektioner vid musikreproduktion
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
Aktivitet som sjukdomsmarkör på kalvar i gruppsystem :
Since long, Sweden has had exceptionally low calf mortality compared to most
other countries. The tradition has been to keep calves in individual pens. With
increasing number of cows per herd there is now a larger interest in more efficient
and economical group systems for housing calves. However it has been noticed
that bigger herds have more health problems and higher calf mortality than
smaller herds. The early signs of disease are harder to detect when the animals are
not fed manually.
Får vårdpersonalen bästa tänkbara IT-stöd? : Kartläggning och analys av informationsflödet mellan EPJ systemförvaltning och vårdpersonal
In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.
Corporate Social Responsibility - A case study about how to improve a company?s CSR work
Background: Since the start of the twenty-first century it has become very important for companies to act in a responsible manner, in guides of CSR. The idea is that companies have more responsibilities than to achieve a higher profit for their shareholders. They should also care about the society and act in a responsible way.Problem discussion: Problems concerning CSR are that the internal part of the sustainability work has not encountered the same level as the external part of the sustainability work. Companies are today struggling with implementing CSR into their business strategies.Research questions:1. What does a company has to consider when working with CSR? 2. How can management control systems help the implementation of CSR into the organisation?Purpose: The purpose of this thesis is to examine what a company has to consider when working with CSR and how management control systems can help the implementation of CSR into the organisation.
Utvärdering av informationssystem vid företagsförvärv: Synergiers påverkan på informationssystems integrationsroll
The numbers of mergers and acquisitions have increased significantly in the last period of time. Although this popularity for mergers and acquisitions, most of the mergers and acquisitions fail to create value. One explanation to this failure of value creation is, according to several studies, how companies treat integration of information systems in the pre-merger evaluation. The research within the field argues that information system integration should have a proactive role in mergers and acquisitions, meaning that information system integration should support the organizational change and normally be considered in the premerger evaluation. The aim of this thesis is to study issues that affect whether companies choose to consider information system integration proactively, when involved in mergers and acquisitions.
ADS och Matlab för optimering av pre-distortion av effektförstärkare
This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.
Det talas om förändring : en studie av den svenska museivärlden
The Swedish museum world is a complex and disputed field. Changes are high on the agenda, but they are neither easy nor self-evident. This master thesis looks at how Swedish museum professionals discuss changes and how they envision museum work for the future. It is also an analysis of the current state of the field. We have made a critical discourse analysis of three recent projects; Svåra saker, Museum 2000, makten.nu and the debate articles from the journal Svenska Museer from 2000 to 2001.
Enterprise Resource Planning Systems as a Service: Hur genomförs en framgångsrik implementation?
Denna uppsats har sin utgångspunkt i den tekniska evolution som har skett i affärssystemens värld. Syftet var att undersöka och beskriva implementat-ionsfasen av ett Enterprise Resource Planning System som tillhandahålls som en tjänst via internet. Fokus var att identifiera framgångsfaktorer för implementationen med hjälp av ett fallstudiebaserat tillvägagångssätt där tonvikt legat på intervjuer och andrahandsmaterial. Undersökningen visade att bland annat valet av ett för organisationen passande system, en omfattande verksamhetsanalys, implementeringshjälp av konsulter samt anpassning av affärsprocesser är viktiga faktorer för en framgångsrik implementation. Därtill såg vi att en tydlig projektplan, en Project Champion och dedikerade resurser också var viktiga faktorer för framgång..
