The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

Development of services that?s provided through mobile application technology in today's modern IT society has become a full-fledged market where numerous players trying to make themselves heard in everything from innovative new services to the further development of existing services. In these services actors wants to find new areas of use by taking advantage of the mobile technology.We have investigated how value is created and how the value is captured in the services provided through mobile applications. Through this, we wanted to identify the critical success factors in how a newly developed service should be designed to create value. This has been done through a thorough literature review, together with an indepth evaluation of existing applications.

The function of budgetary controls is to control the resource allocation within companies. It can also be an instrument for measure and control subordinates and/or business units? performance (Van der Stede 2001). This paper concerns the latter; when the budgetary control function is used to measure and control subordinates performance based on budget. Previous research in this area has not yet accomplished to explain the effects of tight budgetary control which Hartman (2000) considers as the main issue to be concerned about in management accounting research.Previous research has presented contradictory findings regarding tight budgetary control explained by positive effects as well as negative effects during the last decades.

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.

Problem discussion: Syncron experience a challenge in realizing the full market potential of its newly developed IT-based price management system, Global Price Management (GPM). The system has already been implemented and is currently running with success within the IT-structures of the first customer. The fact that the development of the system has been initiated by a customer, and thereby has left Syncron oblivious of the real underlying drivers and incentives for the development, is part of the problem. Understanding the customers? incentives for developing their pricing process thus reducing the application uncertainty is a good starting point.

The aim of this thesis is to explore the institutional design of Participatory Budgeting (PB) in Sweden and how the design may contribute to realize central democratic goods. The study records the different PB experiences in Sweden and focuses on one particular case, which is the only case that successfully qualifies as a genuine PB-process according to international standards and definitions. To examine this, the following questions are asked: which municipalities in Sweden have implemented Participatory Budgeting? How can the institutional design of Participatory Budgeting be described and to what extent does it enable the realization of central democratic goods? To what extent does the institutional design enable the realization of the democratic goods inclusion, popular control, considered judgment and transparency? To what extent does the institutional design enable the realization of the institutional goods of efficiency and transferability?The study is based on an institutional theory of democracy. The method used is a mixed method ideal type analysis that combines document analysis, surveys and interviews.

This essay focuses on the theory of classical realism from two points of views. Realism is often told to be quite immoral and cynical and only interested in the power relations among nations. In the first part I am arguing that this picture is wrong and should be revised. By using the ethical theories of deontology and utilitarianism I am arguing that both these perspectives can be used to analyse classical realism. By defining a value that should be guiding one can assert that realism is a good moral theory.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

In healthcare settings, administrative routines have been made more efficientthrough digitalization of information and the introduction of stationary computers.This situation is especially true when it comes to radiology, where pictures,referrals and patient information now is completely managed by advanced stationarycomputer systems. However, studies have shown that these rationalizationsdo not support flexible and mobile work routines.PocketRIS is a prototype illustrating a mobile terminal for radiology that hasbeen designed to simplify workflow and reduce the cognitive workload of healthcarepersonnel. PocketRIS includes a visualization of the clinicians work situationincluding a personal referral list that can make the user attentive of importantevents.Contextual Design has been used to elicit the basic system requirements for thesystem; 19 contextual inquires was conducted with physicians, nurses and assistantnurses at two different radiology clinics in Sweden during six days. The purposeof the study was also to identify the groups that have the greatest need for amobile terminal. The study was concerned with design and evaluation of differentsolutions with healthcare personnel.The result shows that physicians and assistant nurses have the greatest need ofa mobile terminal.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

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.

This study, which was conducted in Sweden, was based on four qualitative semi-structured interviews. The aim of this study was to create an understanding of how a municipality designs the sanction for youth offenders called ?youth service? based on the law that establishes the existence of such a sentence. We interviewed social workers that work at the department of youth service in the municipality of Gothenburg, who exclusively deal with youth offenders? sentenced to youth service as their job assignment.
