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.
Systemen med rätt inställning - En studie om whistleblowingsystem i Sverige
In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".
Gulliver Simulation - En systemarkitektur f or n atverkssimulering av
Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.
Virtuella Communities: Sociala faktorer i digitala miljöer
Virtual Communities is an increasingly common phenomenon on the Internet. Most
of the Virtual Communities are operated and maintained on a non-profit basis
with a direction towards entertainment. However, as more state administrated
and commercial services become web-based, we believe that the number of Virtual
Communities with a community-based or commercial direction will increase in a
near future.
In this thesis, we describe our participation in, and studies of, a
number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On
the basis of our experiences, we describe the social elements that form the
foundation on which the Virtual Community rely on.
Beslutsstödsystems inverkan på Sveriges landstings upphandlingsenheter. En kvalitativ studie om beslutsstödsystem inverkan på planering ? och uppföljningsprocesser inom Sveriges landsting
Many organizations utilize decision support systems in order to handle different tasks and tosupport the decision-making process. Decision support system is a broad term used to referto several different types of systems. These types of systems can handle a wide range ofoperations within the organization. Consequently this will have an impact on differentoperations within the organization. The main aim of this study was to create a betterunderstanding regarding the impact of decision support systems on the various operationswithin the City Council's procurement units which in turn will increase effectiveness.
Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata
Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.
Hör upp!!
In this Bachelor thesis I explore sound and room as elements in design of user
interfaces, both theoretical and practical in a specific application domain, to
identify some of the advantages and disadvantage associated with these elements.
As application domain I studied email clients and their usage at home amongst
students at Blekinge Institute of Technology. In the study I found an activity,
which seems to be highly distributed in the physical room where the user is
located. The activity was notification of email and could take place in an
arbitrary location of the home. I then augmented this activity with ideas from
my theoretical assumption about room and sound.
The result was a rule-based agent for notification of
email, which primarily uses sound as interaction style..

Datorer i förskolan - barns nya kultur : barnvakt eller ett pedagogiskt hjälpmedel
In this essay I have chosen to explore how computers are used in preschools. The study was done as a survey. How does preschool seize the children´s culture? In today´s society ICT and computers are a big part of children´s everyday life and reflects on their upbringing.Since I am using computers as a pedagogical tool in teaching the children at my preschool, I find this topic interesting to explore.Are the teacher´s using computers for an educational purpose with the children at preschools or are they using it in other ways?Do the teachers think they have the required knowledge to computers usage in teaching the children in a pedagogical way?What is the teacher´s attitude towards computers in preschool?The essay starts with a introductorial background section where I talk about my own experiences of using computers with the children in my preschool, and then referring to the society then and now, school law, curriculum, teachers' computer skills, media situation amongst children and young people, computer use in preschools/schools and health effects. I have composed a survey based on the answers of 50 teachers in 30 different preschools and in nine different municipalities.The result of the survey is reported and concludes with a part of discussion, where the results are put up against the introductorial background section.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Ergonomiska förhållanden för mjölkare i olika mjölkstallar :
Earlier studies of musculoskeletal problems with milkers working in milking parlour
operators have shown that it is a physically demanding occupation. The extremities that are
most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in
present cases are fishbone and some tandem barns.
There have been changes in the working environment during the past ten years. The
mechanisation has been developed for the better with automatically removers of the milking
units and vertically adjustable floors in almost every daily milking barn. In other hand the
milk production are more industrialised and more related to stress today.

Radioräckviddsberäkningar för flygande plattformar
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.
