Mjukvaruplattform för riggstyrning

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Validation of Steins/Arla Foods method for lactate fermenting clostridia in milk

One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.

Afasi och luktförmåga

Att perceptuellt uppfatta och identifera lukter påverkas av en rad olika kortikala system och kognitva förmågor. Syftet med föreliggande studie var att undersöka huruvida personer med afasi har en luktförmåga som skiljer sig från normalpopulationen och ifall en afasiproblematik påverkar de faktorer som normalt involverar luktförmågan.         I studien medverkade tio försökspersoner, sex män och fyra kvinnor. Personerna hade varierande grad och typ av afasi och var mellan 42 och 76 år. Deltagarna delades in i åldersgrupper där två personer klassades som yngre och åtta som äldre. Samtliga testdeltagare genomförde två olika lukttest: Odor Threshold Test (OTT), och Swedish Odor Identification Test (SOIT).

Rätt person på rätt plats: Sambandet mellan personlighet, yrkesval och arbetstrivsel

This study investigated the relation between Extraversion and Conscientiousness with job satisfaction and job selection in the two occupational groups of telemarketing and administration. The study also set out to explore the relation between social desirability as assessed with an Implicit Association Test (IAT) and total reaction time on the IAT. The questionnaire was administered over the Internet to forty-one subjects (24 women and 17 men) in the age range 16-65. Results indicated that people working with telemarketing tend to be extrovert while people working with administration often are conscientious. Job satisfaction correlated with Extraversion in the telemarketing group.

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Nedfästning av oljemåleri på puts.En fallstudie från salongen på Mostorps slott i Halland

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

Uppföljningsverktyg för analys av användarloggar

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Kapitalstruktur och Affärsrisk

During the past year it has been made possible to buy back a company?s outstanding stock. This is done in order to change the capital structure towards a situation with less equity. A change in capital structure means a change in the cost of capital for a company and by that a change in the value for the stockholder. This Master Thesis studies the relation between capital structure and business risk.

Sociala nätverkets betydelse för vägen ur hemlöshet : En narrativ studie

The aim of this study was to use stories from three people who previously lived in homelessness to increase the knowledge of the social network's impact on the process of exiting homelessness. In order to answer our questions, whether the social network facilitated or hindered the way out of homelessness, we have used a narrative method to take advantage of these person's life stories. As a theoretical perspective, we used the ecology of human development, based on the idea that human development occurs in interaction with their environment at different levels. Results showed those interviewees' networks had a significant impact on their path out of homelessness and that these relationships both facilitated and hindered this process. At the same time, these relationships affected our interviewees in different ways and were found in various areas of life, which indicates that there is more than one way out of homelessness.

Arbetssättets betydelse/påverkan i matematikundervisningen : En kvalitativ studie av etniskt svenska respektive etniskt utländska elevers resultat/förståelse i förhållande till matematikundervisningen

This thesis which is about working with mathematics teaching has no effect/impact on performance and understanding of pupils. The study is intended to gain insight on working in mathematics education which has an impact on performance and understanding of students who are ethnically Swedish and foreign ethnic. In order to compare the ethnic Swedish and foreign students of ethnic understanding, I judged from their performance on the tests taken in year three. The qualitative approach permeated the work, both interviews and observations which were included in the survey. The qualitative study was chosen to get an understanding of how mathematics teaching is conducted in two different areas.

Gymnasiereformen 2007 : En studie om förändringarna inom biologiundervisningen och hur en öppen process bemöts av aktörer i skolans vardag

Next year, Swedish upper secondary school will be the arena for a new comprehensive reform according to an extensive government bill. The reform will probably have major impact on every-day educational practices. The aim of this paper is to describe the consequences forbiology teaching when the reform is implemented, and to analyse in what way the biology teachers, and other participants, take part in digitised discussion forums during the implementation of the reform.The research design consists of a quantitative approach and two different methods are used, i.e. descriptive content analysis and quantitative content analysis. The content and meaning of the government bill is analysed and the statements from the participants at the discussion forums are equally important in order to fulfil the aim of this inquiry.The results show the reform will have a profound impact on the subject biology, e.g.

EU- medborgarskap Utifrån ett individ- och arbetstagarperspektiv

The EU- citizenship was established in the Maastricht Treaty in 1993. This citizenship involves rights to free movement, election rights to the European Parliament, diplomatic protection and the right to petition to the Ombudsman. In my analysis I discuss the implications of the EU- citizenship for the individual. The development and legal status of the union citizenship is examined in order to give a general understanding of the implications. In addition, I conduct a case study concerning the EU- citizenship's impact on workers rights.

Sambandet mellan saldodifferenser och effektiva materialflöden : Fallstudie utförs på Atlas Copco?s logistikavdelning

Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.
