As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

This essay has discussed and analyzed a draft for an idea about a network called EduSync. This idea is based on that teachers and students, attending and holding courses, all over the world should be able to find and interact with each other. EduSync is founded from a new learning theory, connectivism. Interviews, participation in a conference and two workshops have been used to gather information and different points of view concerning e-learning, for example possibilities and problems with this idea of a network.  A comparison of web communities and e-learning environments that exists today was also done. The gathered information from persons as well as literature resulted in a discussion concerning learning and what would or would not be possible with the creation of EduSync.

Welfare is every person's right. To create conditions for a good welfare it requires coordinated strategic interventions at national and local level. Efforts must be politically supported to be able to strengthen public health. Local welfare management is a measure used to control and monitor public health. The purpose of this study was to investigate local actors perceptions of collaboration in strategic public health efforts with local welfare management in a municipality in central Sweden.

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.

The study consist of an investigation regarding the implementation of reassurance policing in Sweden and include a survey conducted among some of the local police offices in Stockholm County. The aim of the study is to investigate how the police officers working in the local polices offices experience the implementation of the local police offices and if the implementation of local the polices offices matches the police authority´s purpose with the project. The study uses the theoretical framework from political scientist Michael Lipsky calledStreet-level bureaucracy - Dilemmas of the individual in Public services which discuss the role of street-level bureaucrats and their influence in the implementation. Included in the study is also two different perspectives on governing in public sector called top-down perspective and bottom-up perspective. The findings of this paper shows that the police officers are in general positive towards the implementation and that there´s a duality among the police officers regarding the proximity to the citizens..

The work with Agenda 21 resulted in a larger focus on local participation and deliberation. The Swedish implementation of Agenda 21 is a result of these local governments´ political agendas and policies.The purpose with this paper is to examine the relationship between the citizen and the local government. It focuses on three theories of citizenship and how the view of "the environmental aware citizen?; in the local government?s municipalities policies differ and from which theory of citizenship do they come from.The analysis is of a valuing and comparing nature. The municipalities´ web pages have been the main source to generate an understanding of their view on the normative environmental work.

The purpose of this thesis is to outline an appropriate model in order for companies to successfully act and compete physically as wholesalers at the same time as acting on the virtual market by selling directly to the end consumer. The approach of this thesis is hermeneutical and abductive with elements of hypothetically deductive approach. Our research has a qualitative research strategy based on case studies and interviews as well as on secondary data. Interviews were conducted with the case company JaymJay Wear AB as well as with other companies, so called mini cases. The secondary data consists mainly of textbooks, web sites and journals.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

The topic of this essay is the expected effects that can come during and after a mega event and how the local impact may affect the local community and the citizen. This essay concerns a forthcoming mega event, the Olympic Games that will be held in London 2012. The area that the Olympics will be held in is Stratford that is located about twenty minutes from the central of London by the underground. The Olympic Games is one of the largest mega events with its millions of visitors. The purpose of this essay is to study what is expected after the mega event has taken place in London.

Bakgrund: Venprovtagning kan orsaka sm?rta hos barn vilket kan leda till negativa upplevelser och undvikande av v?rd i framtiden.

Syfte: Denna studie syftar till att unders?ka effekten av VR som sm?rtlindring f?r barn i samband med venprovtagning.

This essay examine how temporal claims (past, present and future) are used in two Official Government Reports (SOU) in Sweden considering rape and sexual assault. The Official Government Reports constitute an important and particular system for long-term planning, and the reports are used as an instrument to achieve desirable changes within the nation. The temporal pretensions in SOU 1976:9 Sexual offences: proposed new wording of Penal provisions against virtue, and SOU 1982:61 Rape and other sexual assaults, are analyzed in relation to the concepts realization of the possible and actualization of the virtual, in order to see how the concepts correspond to the process of desirable change in the reports. The temporal claims are used in a spatially sense where space is assimilated to the concept of time which in return create notions of spatio-temporal images of the past, the present and the future. This is partly a problem for the reports in their aspiration to transform old norms and create innovatory values and ideals..

The aim of this work is to understand the recruitment of candidates to the local representative assembly in the municipality of Täby. The method used is qualitative interviewing, of a total of eight local politicians in Täby. The theory in which this work rest upon is based on a new-institutionalist perspective. Of great importance is the thoughts of the politicians involved in the recrution process, what do they think were the reasons that controlled the order of priority in the party list among the pool of candidates? Were there any obstacles for minorities in the politics like for example foreigners, women or young people? The study is taking it?s departure from the politicians who candidated in the election of 2002-2006 and the ones which are candidating to the election this coming autumn.In conclusion the aim is to understand the reasons that gives some of the candidates electable places to the assembly, and what the actors themselves think are the conclusive qualities that matters the most.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
