Borrning och gängning av laxkilar till vågkraftverk med industrirobot

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Test-retest reliabiliteten i balanstesterna Unilateral stance, Limits of stability och Rhythmic weight shift

Människans balanssystem kan beskrivas utifrån tre delkomponenter, det vestibulära, det visuella och det somatosensoriska systemet. En rad olika skador och sjukdomar som påverkar dessa system stör därmed också balansen. Balansstörningar kan verifieras med hjälp av funktionella tester eller teknisk utrustning. Då teknisk utrustning används är det vanligt att instrument utnyttjas med kraftplattor i syfte att mäta det posturala svajet hos patienterna. Vid balansutvärdering är det viktigt att de instrument som används är validitets och reliabilitetstestade.

FLYKTEN FR?N VARDAGEN. Om fantasy, eskapism och verklighet

This paper investigates the relations between the fantasy genre and the phenomena of escapism. It also delves into the factors which motivates consumption of various fantasy mediums. This is done through interviews with six different fantasy-consumers, along with two observations; of which one is performed at a science fiction convention and the other at a table-top role playing game. The study resulted in a basic understanding of escapism ? it is not limited to the fantasy genre, and fantasy consumers do not deny that fantasy is a form of escapism.

HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder

On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

I domen rekonstrueras verkligheten : en dokumentanalys om hur genus reproduceras och upprätthålls i LVU-mål

Title: "In the verdict, reality is reconstructed" - a documentary study of how sex is reproduced in verdicts of LVU-cases.The aim in our study is to see how existing circumstances revolving power between the gender, are contained in court, through language and differences in the sentences and expressions that are used in the verdicts. In this study we have reviewed verdicts about young people who are taken in to custody care by Lag (1990:52) med särskilda bestämmelser om vård av unga.We have reviewed verdicts from the county administrative court in Kalmar, from January in 2007 to October in 2008. Through the analysis we have taken into considerations and worked with earlier research and litterateur containing different theoretical approaches to feminism.The result of the study shows, that despite of a neutral law, girls and boys, women and men are judged and treated different, because of their sex. Depending on your sex, you are expected to behave according to norms and values. These norms and values are not the same for girls and boys.

En kvalitetskontroll - Snustillverkaren Fiedler & Lundgren kvalitetstestas

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

The investi-gation was based on different court rulings of care of youths according mostly to 6 § LVU. Perusal and interpretation of the rulings have been necessary in order to clarify the issues.

Association between animal-based measures and register-based welfare indicators in dairy cows : a study of the advisory service "Ask the Cow" and the web report "Animal Welfare Signals"

Animal welfare can be measured in several different ways; for example by using animal-based measurements. It has been shown that register data from the Swedish Official Milk Recording Scheme can be helpful when identifying herds at risk of having poor animal welfare, which led to a development of the advisory service of ?Ask the Cow? and the web report ?Animal Welfare Signals?. The aim of this project was to find out if register data from ?Animal Welfare Signals? can be used as a screening tool for detecting herds at risk of having poor animal welfare and in need of an ?Ask the Cow?.

Valutariskhantering vid exportaffärer : - en studie av stora svenska exportföretag

AbstractBusiness, or business decisions always involves an endangerment from the company?s aspect, but when it comes to business with foreign countries the risk profile looks quite different from the profile the company has when its doing business inside the country. Therefore, it is extremely important for an export company or import company to carefully consider the risks that are enclosed with the deal, before he makes the decision to enter a deal. One of the most important risks a company have to considerate when doing business with foreign countries is the currency risk. A company is exposed to currency risk when either long-term or short-term changes in the exchange rate may affect the result of the company, competitive position and growth.

Quantitative thermal perception thresholds, comparison between methods

Skin temperature is detected through signals in unmyelinated C-fibers and thin myelinated A?-fibers in the peripheral and central nervous system. Disorders in thin nerve fibres are important and not rare but difficult to diagnose by the most common neurophysiological methods. In this pilot study different methods for quantitative sensory testing, QST, were compared to give some ideas about which method could be the most efficient to use in order to point out injuries of the sensory system in clinical practice. The comparison was made between Békésy (separate warmand cold thresholds) and Marstock test (combined warm and cold thresholds).

Sensory nerve conduction studies in young adults for the expansion of a reference material

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

Revisionens betydelse vid kreditprövning : Påverkan ur kreditgivares perspektiv.

Bachelor thesis in business administration with emphasis in accounting and auditing. Spring term 2011, Mälardalens Högskola.Authors:Jim Hansson, Filip Sahl and Pererik Sewerin.Advisor:Lennart Bogg.Key words:Abolition of mandatory auditing, optional audit, auditor, audit.Title:The role of audit in a credit review - impact from the creditor's perspectiveBackground:As of November 1st2010, auditing became optional for micro companies in Sweden. This leads to an opportunity for about 70 % of the joint-stock companies to choose whether or not to keep their auditors. Creditors are affected by this as they may receive a less trustworthy base to make a good credit review if many companies choose to proceed their accountings without the control of an auditor. Creditors have the option to require that companies are to be reviewed by auditors, while authorized accounting consultants may be a possible substitute as a quality control for the accountings.Purpose:The purpose of this thesis is to examine what impact optional audit has had in credit processes so far and look into alternative forms of reviews for businesses.Problem definition:? Does auditing simplify for the creditors in a credit review? ? Is there some kind of accounting that could be a substitute for the audit?Method:The study is qualitative in character through six interviews.
