Den kollektiva missuppfattningen. En studie om missuppfattningar om färdmedelsalternativen bil och kollektivtrafik, för boende i Hjuvik

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Folkhälsa - "Inte bara en morot i handen" - en kvalitativ studie av det kommunala folkhälsoarbetet i Västra Götalandsregionen

ABSTRACT. Introduction: In the Swedish government?s public health policy the municipalities are emphasized as one of the most important actors. Based on their broad range of operations the municipalities have good opportunities to influence the health situation of its citizens. Aim: The purpose of this study is to investigate how the local public health coordinators in Region Västra Götaland are working and what barriers they experience in their work.

Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

Optimism och stress : En enkätundersökning om förhållandet mellan självupplevd optimism och stress

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

Smarta lokala energisystem, Vision-Teknik-Tillämpning

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.

Utredning av Ljussignal som avståndsvarnare i trafiken

In today?s consumption society, the image and core values of a company have become more important in order to secure the attention on the market. All entrepreneurs have to distinguish themselves in the extremely tight competition.This thesis examines how product photos can reach out to the consumers successfully. Both students have previous experiences from model shoots ? but now want to study the possibilities to sell a product without a human model.The purpose of the thesis is to examine how to convey core values by commercial product photos - how to best capture the attention of a customer.

En LCC och LCA analys av olika fasadmaterial - En studie med fördjupning mot Puts, Steni Colour och Tegel

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Varför Klass? Att studera ojämlikhet ur ett statsvetenskapligt perspektiv

This thesis contains a wider discussion on the analytical framework of classstudies in political science. The purpose is to put class into the light of a usefulmethodological and theoretical tool when it comes to studies on inequality and political,as well as scientific approaches and explanations to why people have awide range of differences in how they pursue their lives. It is my ambition to discusshow class relations can be theorized and explained within a given context, aswell as in society as a whole. I see the complexity of this field as a resource to enhancethe epistemological as well as the empirical discussions within the politicalscience scholars..

It is easier to swallow an elephant in pieces. A way of measuring flexibility and quality. A study of DAS.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

Interaktiv hemsida med PHP och MySQL

This degree project is made for Cervera in Norrköping and Linköping. The task was to create a professional interactive homepage for the company where the company's range of products can be presented. Besides a homepage aimed towards potential customers, an online Internet-application where the company's employees can update, erase, and create posts that are stored in the database was created. The main programming languages have been PHP and HTML in combination with databases in MySQL. The final result was a functional, professional and informative homepage with a simple and pedagogical application for the employees.

"Ibland tror jag man kan ha en dubbelmoral inom sig själv..." : - En studie om gymnasielevers förståelse av jämlikhet på en principiell och konkret nivå

The purpose of this study is, by groupinterviewing students in upper secondary school, to investigate students comprehension of equality on a principle level and a concrete level. The questions at issue are as follows; how is the comprehension on respective levels described and is there any difference or similarities between the two levels? Further more, this study also aims to end with a discussion regarding the result from the mainpurpose in relation to the educational environment. In my conclusion there is to be find a certain difference between the comprehensions of equality on the two levels. The conception of equality is in the beginning principled and there is no exception from the worth of every individual but however, when the conception is brought out in reality it gets depended of its context and the comprehension for equality becomes more dynamic. The project will be completed with a discussion regarding the results in relation to the educational environment. .
