Modellering av hydrauliskt aktuatorsystem

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

En jämförelse mellan traditionell och modern taktäckning av industribyggnader

Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.

Rosa entreprenörer: En studie av homosexuella män som entreprenörer i ett heteronormativt samhälle

Purpose This thesis tries to create an understanding of how male homosexual entrepreneurs, both as persons and as a concept, relates to the fact that entrepreneurship, as well as the society as a whole, is heteronormative. Moreover, it examines by what methods the male homosexual entrepreneurs cope with the seemingly paradox of a homosexual man who also is an entrepreneur. Method The method has been qualitative from a social construction-point of view. We have made semi-structured interviews with nine male homosexual entrepreneurs and structured the findings from the interviews with a computer programme and mind mapping techniques. We have compared the structured findings with theories, in an abducting manner, to find out an answer to the purpose of this thesis.

Tyst framgång: om sambandet mellan informationsdelning och framgång i entreprenörskap

A dilemma often met by entrepreneurs is whether or not to share information about their business ideas in order to increase the probability for success. The reason for sharing information is presumed to be an increased ability to develop the business idea, whereas the reason for maintaining secrecy would be to protect the idea from being stolen. Common as this dilemma is in practice, it is not very well covered in the entrepreneurial theories. The purpose of this thesis is to elaborate the theories in this subject by investigating an entrepreneurial case. The case shows that one possible solution to the dilemma is a situation-based information sharing.

Aktörer och strukturer inom svenska statsvetenskap : En granskning av tre statsvetenskapliga bidrag till aktör - strukturdebatten

The purpose of this essay is to critically review three different contributions to the agency ? structure debate from a political science perspective. My opinon is that the agency ? structure debate is one of the main problems within the social science. The theories which I will examine are Lennart Berntsons theory from 1974, Lennart Lundquists from 1984 and Walter Carlsnaes from 1992.

?Det var en tyst kamp? : En ekokritisk analys om utvandring och fo?ra?nderliga system i Vilhelm Mobergs Utvandrarna

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Varför En Reformerad Gymnasieskola 2011? : En reformanalys utifrån rektorer och lärares uppfattningar ? kopplat till John Deweys teorier.

This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.

Uttorkning av Betong

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

Kvalitet-i-Bruk för Beslutstödssystem inom Thoraxkirurgi

The aims of the practical work carried out for this thesis were to redesign a clinical decision support system for thoracic surgeons, called AssistMe, and to evaluate the concept behind this system. The main objective of the thesis is to give an account of the considerations that were found to be of key importance for designing a clinical decision support system for thoracic surgery. Another aim was to let future users test the system after it had been redesigned and evaluate the concept behind it. The thesis also investigates users? experience of the system and their views on whether it would be applicable in their daily work practice.

Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

Affärsmöjligheter med Smarta Elnät : En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet

Distributed, renewable generation-units and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ?Smart Grid?.This future electric system rise expectations among actors in the existing electricmarket. International organizations share visions of opportunities for electricityconsumers and new actors, ready to enter the market. At the same time, electricutility companies may question the need for some of these upcoming changes, as theyare sometimes expected to lead the development.This paper therefore seeks to investigate the business opportunities related to SmartGrids.

En studie av den svenska människohandelslagstiftningens effektivitet

This paper aims to give a comprehensive view in which extent Swedish legislation concerning trafficking in human beings (Brottsbalken 4 kap. 1a §) is efficient. Qualitative interviews have been carried out with professionals within the judicial system in order to comprehend various aspects of efficiency relating to legislative validation of trafficking regarded human beings.

Aroma Theory: Scenting the Attitude

The thesis examines the relationship between consumer attitudes and a scented shopping environment. A relationship and phenomena concerning scent marketing, which could be seen as one of the more provocative forms of marketing since the human sense of smell, is connected to the limbic system where motivation and attitudes are created. The use of scent marketing has, so far, been proven effective in sales increasing whereas it is one of the less explored forms of marketing.The purpose of the thesis is to answer the following question: Is it possible to find differences in consumer attitudes in a scented buying environment compared to a nonscented buying environment, and thereby create new basis for segmentation?The thesis is based on a quantitative study where data has been gathered in a scent manipulated buying environment through structured interviews with consumers. The thesis applies a deductive approach to the main theories in the area of interest.The findings suggest new theory discussing that it is difficult to use consumer attitudes, towards a scented store environment, as a foundation for market segmentation.
