SEP Modular Armoured Tactical System is the next generation of military vehicles developedby BAE Systems Hägglunds AB. At present time, BAE Systems Hägglunds AB aredeveloping a 6-wheel electrical hybrid and a conventional 8-wheel vehicle. The questionformulation was summarized as: ?In which ways can the electrical transmission in a hybriddriveline for SEP be designed, when the surrounding fixed interfaces are kept and the unity ofcomponents within SEP is maximized??. The purpose of this master thesis was to study avariety of concepts for hybrid propulsion.

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

The objective of this study was to make an inventory and a potential analysis of the organic beef production in the region of Gävleborg, Sweden. A survey was conducted, where a questionaire was sent to all farmers in the region who had environmental subsidies concerning organic cropping systems in 2001. In total, there were 701 farmers, of which 46 % participated in the study. Three slaughter houses were interviewed to get their pictures of the development of organic beef production. The study shows that there are potentials and interests in the region to increase the production of organic beef.

The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

Problem: Our opinion is that it is important to consider about usability in system development. In this thesis we will focus on usability in point-of-sale systems. The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

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.

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.
