High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.

Abstract: The purpose of the study was to analyze the experience of being a woman diagnosed with ADHD as an adult. Another aim was to analyze how the women think itwould have influenced them, if they had been diagnosed during childhood.In the study, with a qualitatively approach, three women diagnosed with ADHD were interviewed. The data was analyzed with qualitative content analysis.The result shows that the women perceived affirmation when they received their diagnosis but they also pointed out that they had wished to receive the diagnose during childhood to avoid unnecessary suffering.The conclusion of the study was that it is essential to, as early as possible, follow up deviances in children and adolescents. Therefore, there is a need for more knowledge of how symptoms of ADHD in girls present itself.It is reasonable to believe that if healthcare and school have increased knowledge of symptoms of ADHD in girls, then these girls would be diagnosed at an earlier time.Keywords:ADHD,women,girls,treatment,self?esteem.

This final thesis is performed on commission of Torsby forestry administration, Stora Enso Skog. Stora Enso Skog is one of the major forestry companies of Sweden. The main business area is located in and around the region of Bergslagen. During the last decade the practice of forest management has rapidly changed due to a new forest legislation. The new law has resulted in that the production goal is equal to the environmental goal within forestry.

Servitut som inte uppfyller något ändamål eller inte använts under väldigt lång tid kallas onyttiga servitut. Ett onyttigt servitut försvinner inte automatiskt från Fastighetsregistret utan kvarstår och skapar en onödig belastning. Syftet med examensarbetet är att utreda hur hanteringen av servitut kan förbättras för att minska antalet onyttiga servitut i Fastighetsregistret.De metoder som används är en litteraturstudie och en intervjustudie. I litteraturstudien undersöks svensk lagstiftning och juridisk litteratur. Utdrag ur Fastighetsregistret och förrättningsakt visas för att ge praktiska exempel.

In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

We have made a qualitative study of what the students at Södertörns högskola use Södertörns högskola?s intranet Kurswebben for and how they experience the use of it. For this purpose we have made a qualitative interview examination with six students. The empirical material has been analysed according to our own analytic model which is based on existing usability theories and consists of the tree parts content, function and design.Our conclusion is that the students use Kurswebben mainly to keep themselves updated, download teaching material and schedules. According to our study, the students most of the time experience their use of Kurswebben as simple, but sometimes have a reluctance to visit it.

Degeneration of trademarks - a legal construction or a marketing problem? This paper discusses the issue of degeneration of trademarks. The study has its starting point in the conflict that may arise between the principles of marketing and the legislation concerning IP rights and market law. In this study several verdicts are studied in which degeneration has been addressed. Analyzing these rulings as well as the current legislation in the light of marketing theory, a conflict between marketing and legislation can be noted.

Regardless of what discipline nurses work in, wound care is one of the tasks. Caring for wounds involves early detection of signs of infection, in order to avoid complication. Wound infection extends suffering for the patient and causes unnecessary costs for society. The aim was to describe how nurses can identify infection in wounds. Method: The design of the study was a literature review, where13 scientific articles were examined and analyzed.

Pressure ulcers cause a lot of patients unnecessary suffering. This suffering could be decreased through improved knowledge about prevention, so that pressure ulcer will not appear. The purpose with this review was to study how nurses assess risk and prevent pressure ulcer, and to study how nurses use available knowledge. The method consisted of searches in databases and searching trough references. Our result is based on ten articles, qualitative, quantitative and reviews.
