Modellering och design av elmotor för mutterdragare
This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.
Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.
The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

Eutanasi : en skonsam död
This work is about euthanasia and how to use it on horses, dogs and cats.
A description for each animal is done, about when it is time, why, which methods can be used and who is allowed to use them, how and where it shall be done.
The methods we have concentrated on are:
- Chemical destruction and the most common drugs for euthanatize horses, dogs and cats.
- Physical disruption of the brain activity by a captive bolt, only for horses.
The captive bolt only makes the horse unconscious and must always be followed by cutting off the vena jugularis. Then the horse dies because of loss of blood.
No matter which method used for euthanizing, the animal must be declared to be dead by the operator before other measures. The testing criteria for death: muscle relaxation and cyanosis, cessation of reflex activity and pupillary dilatation, cessation of respiratory activity and cessation of all cardiac activity.
"Jag letar efter tjuven så letar du kapsyler" : En undersökning om vad barn kan lära sig genom pedagogiska dataspel i förskolan
This thesis treats the extended Swedish rules regarding deduction limitations on interest. The purpose for this thesis is to investigate whether the interest deduction limitation rules have potential to protect the Swedish tax base. The thesis also assesses whether the options presented how the extended rules could look liked had been better to protect the Swedish tax base. Furthermore thin capitalizations rules have been evaluated if this is a better method to protect the Swedish tax base.In 2009 the Swedish deduction limitations rules on interest came in to force to protect the Swedish tax base. Despite these rules companies was still able to avoid Swedish tax and therefore threatened the Swedish tax base.

"The only options we have left are socialism or barbarism." - En studie av tre nutida latinamerikanska vänsterregeringar och av orsakerna till att de har uppnått olika demokratigrader.
This comparative case study, which is based on a most similar system design,investigates why the Chávez government has attained a lower degree of democracy than the Kirchner and the Lula governments. In order to develop asupplementary theory about why governments in general achieve various degrees of democracy I compare these governments and examine what policies that differ them and why. My results show that these governments? policies differ concerning the rule of law, militarization, and negotiations with economic groups and anti-regime parts of civil society. I have found numerous answers to why some of these governments (and governments in general) have democratic policies within these four areas and why some do not.
Riktig svenska : Om andraspråkselevers ämnesval och litteraturläsning på gymnasiet
The purpose of this study was to look into how learners of Swedish as a second language and some teachers of the subject think and reason about the choice between Swedish or Swedish as a Second Language and literature in Swedish at upper secondary schools. Similar studies have earlier been carried out at upper secondary schools in areas dominated by immigrants while the present study has been accomplished in a small municipality with comparatively few immigrants. The study is based upon qualitative interviews which have been analysed through the socio-cultural theory regarding those artifacts, communication and that mediating second learners of Swedish and their teachers and schools are using in their choices between Swedish or Swedish as a Second Language as well as selection of literature in literature teaching. The study also shows how learners of Swedish as a second language perceive the choice between the two options of Swedish courses at advanced upper secondary school and how their teachers look upon their choice and the information given. Furthermore we will also get to know the learners of Swedish as a second language and their teachers? view on teaching Swedish literature at advanced upper secondary B-level in Swedish.

Varumärkesutvidgningar för Personliga varumärken vs. Företagsvarumärken - Same same, but different
Today, branding is not a phenomenon but rather a prerequisite for a brand to be able to both survive and grow stronger. During the last couple of years, personal branding has come to be an established term, just like corporate branding. With the growth of the social media and the thousands of ways to interact with each other personal brands face great competition. It is more difficult than ever to maintain a strong brand, partly because of this. There are several growth options for brands.
En förbättrad rullstolsplats på klass 1 bussar : I sammarbete med Benteler Engineering Services
The initiative for this project was taken by Benteler Engineering Services, as a result of having identified areas of improvement, in designated accessible areas like the wheelchair spot onboard buses. Depending on a wheelchair to be able to move around can understandably be challenging.Public transport is a common good in today`s society, however despite the measures taken towards adjusting to accessible needs, the majority of those being disabled chose different alternatives of transportation. This is due to reasons such as the drivers' poor attitude, furthermore the limitations of the space allocated to accessible needs, as people with strollers also use these spots onboard. Also, some wheelchair users find the rides unsafe, as they could easily fall over during without the appropriate space for them onboard the buses etc. These are only a few reasons why other options are sought out, i.e.

Förändring av verkstadslayout på Munters AB
The Energy Performance Certification in Sweden was developed as a tool to achieve the Government's target to reduce Sweden's energy consumption by 20 percent by 2020. The Energy Performance Certificate has previously received some criticism for not fulfilling its purpose. Questions that formed the basis for this report is how the energy performance certification provides support to buyers of single-family houses and if the energy performance improved in terms of reliability. The report begins with a background description that describes how the energy declaration works and some of the findings of previous evaluations and surveys. A survey to investigate the broker's position to energy performance have been conducted as well as interviews with buyers and sellers of houses. An investigation whether the energy performance can vary between different calculation programs, depending on various assumptions made by the energy declarant, has been made.Brokers and sellers have proved negative attitudes towards energy performance, particularly brokers.
