Furthermore complements to toothbrushing are treated, the options and their effects.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency Scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

Author Cocitation Analysis (ACA), multidimensional Scaling (MDS) and Social Network Analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.

Som en avslutande del i utbildningen ?Samhällsbyggnad - samhällsplanering? vid Luleå tekniska universitet skall ett examensarbete genomföras. Då ett flertal kurser innefattande CAD under utbildningens gång genomförts samt i och med ett stort eget intresse av detsamma kändes det för mig naturligt att genomföra ett examensarbete i någon mening omfattande konstruktion i CAD.Detta examensarbete har genomförts i uppdrag för Lindbäcks Bygg AB i syfte att förbättra den i dagsläget något ineffektiva arbetsmetodik som vid framtagning av ritningar används. Huvudmålet med arbetet har varit att ta fram en manual över ett alternativt, förhoppningsvis bättre, tillvägagångssätt i den arbetsgång som projektörerna utför. Det verktyg som främst använts för att skapa metodiken är ?annotation Scaling?, ett verktyg vilket syftar till att koppla modell till ritning genom skalfaktorer.

The aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and multidimensional Scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A Scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

The purpose of this thesis is to identify and analyse the view and consciousness of history present in essays written by Swedish high school students in 1877 and 1929. A theoretical framework was established in order to accomplish this, based on the theories of Peter Aronsson and Jörn Rüsen (through Lars Andersson Hult) that defines consciousness of history through a matrix that expresses a progression as well as a Scaling complexity. Furthermore, the theories of Knut Kjelstadli and Magnus Hermansson Adler were adopted to establish two different types of view of history: one adhering to a view of history where groups and individuals are seen as integral to the progression of history, and the other explains historical process through more functional explanations, such as dependant on cultural and social structures.This framework erects ideal-types of different types of view and consciousness of history, and the thesis at hand strives to categorise the different kinds of view and consciousness of history found in the studied essays in accordance with these ideal-types through two different models based on the above mentioned theories.The findings presented here largely point to a view of history that is largely centered on an actor-oriented view of history, where individuals such as kings and generals are given a central position when historical events are being narrated, and is present in both 1877 and 1929, with some shifting nuances. As for the consciousness of history the lion part of the analysed texts can be seen adhering to a more traditional type of consciousness in 1877, although a slight shift can be seen towards a more complex type of consciousness in the texts from 1929..

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.
