Statistisk analys av partiella urladdningar

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

Avståndsmätning med Hög Noggrannhet till Låg Kostnad

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

Det vidgade textbegreppet : I teori och praktik

The essay is about the concept of text in a wider perspective, what can be included in that, how it can be used and above all, why one might want to use it. The essay will also include what the term popular culture implies, and school?s attitude towards it, since some of the medias that are a part of the text in a wider perspective, many times fits the description ?popular culture?. Most of the earlier research show that the positive aspects of the use of text in a wider perspective as the same time as it attacks school because school is opposing the popular culture.       The essay consists of two parts and it begins with a theoretical part where I present existing research about the concept of text in a wider perspective and the research about popular culture.

Bygga för ombyggnad : Från parkeringshus till studentbostäder

Detta examensarbete bygger på ett förslag från vår näringslivskontakt Sara Eriksdotter som är anställd på Haninge kommun. Förslaget bygger på konverterbara byggnader. Målet är att bygga ett parkeringshus som går att byggas om till ett flerbostadshus i framtiden. Idén grundar sig på Haninge kommuns plan att arbeta för ett minskat bilanvändande i centrala Haninge, vilket på sikt kommer medföra ett minskat behov av parkeringsplatser jämfört med idag. Samtidigt vill Haninge kommun ta hänsyn till det bestående behovet av bostäder.Vår målsättning med examensarbetet har varit att ta fram ritningar och illustrationer som visualiserar vårt förslag på en konverterbar byggnad; i detta fall avser projektförslaget en byggnad som ska klara av ombyggnaden från parkeringshus till flerbostadshus avsedd för studenter.Arbetsgången för att nå målet började med en litteraturstudie i form av böcker, elektroniska källor och intervjuer med relevanta personer.

Finansiering av företag : är bristen på externt kapital en faktor som hämmarlandsbygdsföretagens tillväxt?

The interest in businesses active on the countryside and their funding situation has increased in recent years. In a survey, conducted by Leif Berndtsson (2003), it was reported that there is a lack of external capital in rural areas. According to Berndtsson (2003) the lack of external capital inhibits the rural firm?s growth. The essay attempts to answer whether the shortage of external capital is a factor that inhibits development for rural businesses.

Upp eller ut? Ut tack!: En studie om frivillig personalomsättning på managementkonsultfirmor

The purpose of this thesis is to understand the reasons to why management consultants choose to leave their positions at large and established management consultant companies. The empirical data are made up of eleven interviews with men and women, both management consultants that have left their previous positions as well as a consultant who has chosen to stay with her first company and a representative from one of the large companies active within the management consultant industry. We have used the Job Embeddedness Theory combined with theories about identity, legitimacy, institutional norms and gender in order to understand the thoughts and reasoning behind the management consultants´ resignation. We have found that issues with the work itself and characteristics of the industry prevent the management consultants from being embedded within the management consultant company. Rather, some of the characteristics of the industry such as ?up or out? and the need to constantly perform work as a ?pushing-out mechanism?.

Färdvägsmiljöer vid cykling för transport : En studie av en modell om uppfattningar av färdvägsmiljön hos cyklister

SummaryAimThe study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three appraisals (unsafe/safe by traffic reasons, stimulating/inhibiting route environment, unsafe/safe by other reasons) in the model´s second level relates among themselves and if these three appraisals can capture the degree of environmental well-being/unwell-being in the model´s third level. The questions were: Do the three appraisals differ among themselves? What is the difference/-s in such cases? And, is there a correlation between any of the three appraisals and environmental unwell-being/well-being? What is the correlation in such case? MethodThe gathering of data was done through questionnaires.

Med samtidsperspektiv på äldre konst : en fallstudie av utställningen "Queer: begär, makt och identitet"

The aim of this essay is to study how older art can be used to illustrate our contemporary society with a critical view and also to contribute to the discussion of for what reason we keep our public collections.My essay is based on a case study of the 2008 summer exhibition ?Queer: desire, power and identity? at Nationalmuseum. The exhibition used art from different eras to show how the ideals, norms of gender, and how the symbols for power have changed throughout history. It also reveals how certain art or artists have been excluded from art history due to their sexual orientation.This study is based on three questions:-          How can older art be used to illustrate a to our society contemporary theme?-          How can a public museum make an exhibition with a clear and active message?-          How can a clear and potentially sensitive message be shown without risking to be provocative towards either the visitors or the person(s) it is about.My material is based on the exhibition, the work material from the museum, protocols, photographs, exhibition texts, and interviews with the creators of the exhibition.

Embryonal näringsförsörjning hos sandtigerhaj och kortfenad makohaj

In this report female farmers use of technical equipment is investigated. There is little research made on this subject in Sweden, therefore this report can be seen as an explorative study. Research makes it clear that machinery, throughout history and even today, has been seen as a male area. Heavy machines are often associated with the same attributes as masculinity. Force, power, efficiency and control are some examples.

Cause-Related Marketing: En kvalitativ studie i hur Cause-Related Marketing påverkar svenska konsumenter

Cause-Related Marketing (CRM) is a marketing activity that has grown popular in the USA and studies have been carried out that explore how American consumers perceive and react to CRM. In Sweden, however, CRM has not yet found ground to any greater extent, and therefore there is limited research on how Swedish consumers react to CRM and how they perceive it. In this study, eight Swedish consumers are interviewed regarding their perception of CRM. The main findings of the investigation are that Swedish consumers fit well into a model that is based on American consumers? responses to CRM.

Expediternas actio : En studie om tio expediters kroppsspråk i två saluhallar i Stockholm

This study analyses the german writer and artist Unica Zürn´s novel, The Man of Jasmine,1970 (Jasminmannen). Zürn was mostly active in the surrealist avantgarde in Paris during the 1950ies - and 60ies. The male surrealist images of women was polarised in to the godlike, child and the erotic, convulsive object. The mythologizied woman was the muse of men´s creativity. But still there were many women artists who participated in the movement, so clearly there was something in surrealism that attracted women.
