The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Another part is support in both telephone and personal visits.Because the number of clients is high and the flora of different automation systems is big the consequence is that the employees must have access to many licenses with programming tools.

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

In several cases, systems that have been developed have been very time consuming and cost a lot of money, but they still do not fulfil the users requirements and requests. To make new systems better, you have to find a way to communicate that allows the developers to understand the needs of the user. The aim for our thesis is to highlight the importance of communication in system development. To investigate this we have choosen to do a study of the real-estate system. The work methods that have been used include mock-ups and informal conversations with the user, who is employed by the Church of Sweden in Ronneby.

There are widespread discussions about the use of retouched models in media, ranging from bloggers to legal decision-makers. Research shows that there are negative psychological effects on especially females being exposed to idealized, retouched model images. The purpose of this paper is to explore the effects of using retouched models in advertising from a marketing perspective, based on attitudes, perceived quality and purchase intentions.Based on theories about attractiveness, halo-effects and social comparison, an experimental study was done, investigating the different responses on above mentioned parameters to advertisements showing either retouched model images or non-retouched model images. Initially it was also tested if the retouched models were seen as more attractive than the non-retouched models. The results showed almost no differences between the reactions to the advertisements with retouched models compared to the advertisements with non-retouched models, when all respondent groups were analyzed together.

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.

For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof.

Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.

The purpose of this essay is to examine how officials within the Swedish public libraryorganisation view the IT-development, how the IT-development progresses within theorganisation and if there is a need for a national IT-strategy for the public libraries in Sweden.Four unorganized interviews with officials within the regional- and county libraryorganisation and one within the national organisation where conducted. This study is aqualitative examination where the phenomenographic approach has been used as inspirationfor the analytic model. The analytic result has been compared to the system theory of how anoptimal system should be constructed to perform in an optimal way and to be able to producegood results. The results of this study show a wish for a better national cooperation regardingthe IT-development for the Swedish public libraries. Today?s library structure should bereviewed over in order to enable the libraries to produce even better results from the cooperation?s..

During the later parts of the 20th century there occurred several changes to the Swedish public sector. These changes aimed to effectivize and decentralize the governance model in the public sector. One of these changes was the municipalization of the school system, put forward and proposed by the social democratic government in the late 1980s and early 1990s. This study aims to examine and compare that times different parliamentary parties' opinions on the municipalization of the school system. The source material consists of government bills, and in direct relation to the municipalization of the school system.

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.

Användaracceptans är en viktig del i alla systemutvecklingsprojekt och är också en väldigt lättpåverkad variabel för en lyckad implementering. Därför är det viktigt att ha översikt på sådana faktorer som kan påverka användaracceptansen negativt, en sådan faktor är försening. Denna uppsats belyser sammanhanget mellan hur en försening påverkar användaracceptansen. Genom att låta en undersökningsgrupp genomgå en enkät utformad efter Technology Acceptance Model har jag samlat upp en generaliserad åsikt. Resultaten visar att försening som variabel inte påverkar användaracceptansen för fallstudien..

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

This report describes the development of a RESTful web service for mobile applications. The web service makes resources from an existing system called kompetensdatabasen ("the competence database") available. Kompetensdatabasen holds information about the capabilities of consultants and about assignments carried out at the IT consultant business Nethouse AB.The web service was developed according to the principles of REST and ROA (Resource Oriented Architecture) which puts focus on making resources available. The resources are made available through the HTTP protocol and the methods associated with it. This means it was designed to use the same technologies as the world wide web.

That many creative workers have uncertain and uneven incomes is well-established, but how or why they make a living is not. This paper examines the elusive value exchanges between creatives, buyers, consumers, and other economic supporters, and offers a model of how creatives make a living. By mapping income statistics of Swedish creatives together with in-depth interviews some patterns emerge. This, combined with Bourdieu's theories of social, cultural and symbolic capital, and Knorr's objects of sociality, forms a basis for a structured model of value exchange. The paper shows how creative workers create economic and non-economic capital (capitalization), how they advertise this capital (signaling), and how they convert between different types of capital (conversion) in order to make a living.
