Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Utvärdering av Windows 8-applikationer ur ett utvecklarperspektiv
With Microsoft's new operating system, Windows 8, a new type of applications were introduced, Windows Store Apps. These applications must meet certain requirements in order to be uploaded to Windows own store for apps. There are also guidelines to follow. The requirements and guidelines include appearance and functionality, such as a common search function in the applications to contribute to a more unified experience. How does these requirements and guidelines influence developers? Whether the development of the Windows Store Apps gets more difficult, or perhaps even simpler, is studied and evaluated in this report.
Att projektera för demontering. Undersökning av stomsystem
The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Automatisk query expansion: en komparativ studie av olika strategier för termklustring baserade på lokal analys
Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.
Beräkningsverktyg för plattformar till seriekompenseringsanläggningar
ABB is one of the world?s leading engineering companies in power and automation technologiesand their solutions improve performance while lowering environmental impacts for energycompanies and industries. ABB FACTS designs equipment and plants for series and phasecompensation.This thesis has been performed at ABB FACTS on the Mechanical Design (DM) department inVästerås, Sweden. The purpose of the thesis was to develop and design calculations andsimulation tools for ABB FACTS?s standard series capacitor platforms.
Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

En jämförelse av krypteringsalgoritmer
Today the Internet is used more and more as a transportation for information.
Much of the information is confidential and should not be read by those not
privileged. To protect the information from unauthorized access cryptography
can be applied. The cryptography algorithms in use today all have their pros
and cons. They are therefore suited for different applications.

Primär eller sekundär söktjänst? En effektivitetsstudie av söktjänsten Google och metasöktjänsten Dogpile
This thesis examines the retrieval effectiveness of two Web search engines. The two search engines are chosen to represent two different types Google as a broad general search engine and Dogpile as a broad general metasearcher. Twenty queries have been used and the first twenty hits for each query were evaluated for relevance. The queries were invented by the authors, based upon their interests and information needs. They were expressed in a general manner, by using one or several keywords, in accordance with the simple search mode available for each search engine.
