In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.

Vid produktutveckling inom industriföretag finns idag luckor vad gäller IT-stöd i arbetets olika faser. Införandet av s.k. RBE-system (Rule Based Engineering) är ett steg på vägen mot att försöka fylla dessa luckor. Meningen med ett RBE-system kan sägas vara att ersätta traditionella konstruktionshandböcker med motsvarande konstruktionsanvisningar i digital form. Detta ger möjligheter till automatisering av processer som är tidskrävande, monotona och ofta förekommande, t.ex.

In the last couple of decades, corporate law firms have rapidly grown to become both influential and highly profitable corporations in the business world. Today, the largest law firms are assumed to bear far greater resemblance to large and often multinational public limited companies than the small businesses generally associated with legal services. However, one interesting specific set them apart from the majority of other companies; the partnership and its interrelated profit sharing. The aim of this study has therefore been to investigate partner compensation systems in corporate law firms and further examine what implications chosen compensation systems have on the organizations. Using a multiple case study, including 7 of Scandinavia?s largest and most well known law firms, the results show that partner compensation systems are highly individual and the critical question is whether to employ seniority based or performance based compensation systems.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

This thesis examines how knowledge management professionals use trust as a component in the creation of knowledge management systems, and what methods they use for building trust.Adopting a grounded theory approach, interviews with 8 knowledge management professionals active in different industries served as the base for an analysis that identified trust to be the single most important common factor in the data. The concept of trust used by the informants was identified as relating to the knowledge management system itself, rather than other users, employees or groups in an organisation.Building trust, the KM-professionals mainly focused on three methods: simple solutions, system superiority, and implementation security. Using these methods, the KM-professionals seek to ensure system trust by creating opportunities for users to obtain positive experiences of using the system, and thereby generate a foundation for a trust-based relationship between the user and the system..

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

The purpose of this master thesis is to, with the strategies of the organization and the preferences of the co-workers in mind, explore how reward systems can be designed in heterogeneous organizations. This is done by interviewing store managers and sales personnel in a heterogeneous organization. The frame of reference deals with theoretical approaches on reward systems and is divided in the following sections, individual or group based, differentiated or not differentiated rewards systems and goals, measurements and rewards. These sections are highlighted from the following aspects, equity, implementation possibilities and finally environment. The theoretical discussion ends in the conclusion that heterogeneous organizations should have several different reward systems, but not if a restructuring process is in progress or the system becomes too costly.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city?s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called ?heatpipe?.
