This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

The purpose of this thesis is to investigate how students who study with Problem-based learning PBL in a distance learning course perceive the support from the university library. I first went into adult education, PBL and distance studies, one at a time, and then took a look at the combination of problem-based learning in distance studies. During the investigation, I conducted five interviews using a phenomenographic method to understand how the students perceived the support they received from the university library. The university library gives a lot of support but what I noticed while I was writing was that it is difficult to reach the students with the information regarding the help that is available to them. I give some example on how to develop the support and find that the students have a wide range of different needs for support from the library depending on their individual situation, social context, academic ability, location and course of study.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

In this essay I analyse the constructions of gender in the series The Phantom by Lee Falk. I apply David Tjeders readings of the bourgouise masculinity, its sensitive character and great risk of falling into unmanliness, when discussing The Phantom?s masculine development. I have analysed three adventures of The Phantom from the years 1937, 1977 and 1996, all authored by original creator Lee Falk. I argue that The Phantom increases his use of violence, therefore risking a loss of character.

The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..

Överkänslighet mot kemiska ämnen i vår omgivning skapar hälsoproblem som ?sick building syndrome? samt ?multiple chemical sensitivity?. Båda tros kunna starta efter långvarig lågdos-exponering av kemikalier som till slut resulterar i en överkänslighet. Symptombilden är blandad och diagnostiseringen svår. Bland annat stress verkar vara en påverkande faktor liksom det kemestetiska hudsinnet.

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

The producers of grain in Sweden are facing a rough future. The competition is getting harder all the time, in Sweden, in EU and also from the ?world market?. The producers have to be more efficient and have to have bigger units. Many producers might have to look for new alternative production opportunities.

The digitization of patient data and medical records used by the healthcare-industry in Sweden is rapidly developing. However; developing and changing things in this field is not an easy task because of the circumstances surrounding it. Digital systems intended to process, and hold, sensitive personal data, such as medical journals, must be developed with laws, confidentiality, integrity and availability in mind to secure that none of this data gets compromised.A complicating factor in regards to this is the fast rate of development within IT in contrast to the much slower bureaucratic process of the justice system. This means that laws and regulations oftentimes aren?t up to date with the newest available technology.With the purpose of establishing set regulations on how patient data should be properly handled the Swedish government enacted the Patient Data Act (sv.

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.

Någon gång i livet kommer de flesta individer tvingas möta på de svårigheter som en sorg för med sig. Sorg är en reaktion på en förlust. Syftet med studien var att belysa stödformer som kan hjälpa individer i deras sorgeprocess. Där sorgeprocessen i detta fall relaterar till förlusten av en närstående. Deltagarna var 23 stycken kvinnor mellan åldrarna 19-62 som hade upplevt en sorgeprocess till följd av närståendes bortgång.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.
