This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Animal welfare in Sweden has gone through major changes during the later years. In 2004, Swedish Animal Welfare Agency took over the central responsibility for the animal welfare from the Swedish Board of Agriculture, and in 2007 the board again became the central authority for animal welfare in Sweden.Even the practical supervision has changed, from the 1 of January 2009 the supervision is to be performed by the county administrative boards, instead of by the individual municipalities. Since 2006 every horse in the European Union has to have an identification card, in Sweden called a ?horse passport? which describes the color and markings of the horse as well as any veterinary treatments.The ELOF-project, a collaborative project between the Swedish Board of Agriculture and the county administrative boards, intends to make the animal welfare supervision effective, standardised, fair and risk-based. Because of the takeover of the supervision and of the ELOF-project the Örebro County Administrative Board has began to make an inventory of the number of horses and horsefarms in the county. Another Ethology and Animal Welfare-student and I did, in collaboration with the county administrative board created a checklist that in connection with the inventory will lead to a risk-based animal welfare supervision.

The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .

The purpose of this Master?s thesis is to examine the accessibility and barriers of public libraries to intellectual and mentally disabled children and young people. This we will do by examining whether the library staff acts according to policies of the libraries. Our method has been qualitative interviews with library staff and we have also observed the environment, media and marketing of these libraries. As a theoretical starting point of the analysis we use Michael Buckland?s different aspects of access to information.

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM?s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.In the Swedish system, SSM?s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility.

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.

This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.

In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.
