VR-verktygets förmåga att återskapa demokratiska processer - Återskapandet av Östra Hamnkanalen

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Jämförelse av analysmetoder för clickstream-data

Det här arbetet har som syfte att genom en jämförelse av olika analysmetoder för clickstream-data kunna fungera som en vägledning när en metod ska implementeras. Metoden som använts vid jämförelsen är litteraturstudie i och med att de analyseringsmetoder som ska undersökas redan är framtagna och kunskap om dem fås genom att studera litteratur i vilka de förekommer. Ett antal kriterier används sedan vid själva jämförelsen, anledningen till detta är att metoderna ska jämföras utifrån en gemensam grund.De metoder som uppfyllde kraven för de olika kriterierna bäst var page events fact model och subsession fact model. Subsession fact model kan dock upplevas som det bästa valet i alla lägen men samtidigt är den kanske lite överdriven om clickstream-datan bara ska användas till att se hur besökarna använder varje individuell sida för att användas i designsupport syfte. Det går alltså att påvisa att syftet styr vilken metod som är mest lämpad..

Vilka faktorer påverkar konkurrensförhållandet mellan en kommunal och en fristående gymnasieskola : en jämförelse av gymnasieskolornas ekonomistyrning och verksamhetsstyrning

When the independent upper secondary schools were started in 1992, it meant a change in the competitive relationship for the local upper secondary schools. A reduced number of students during some years ahead, while the number of independent upper secondary schools increase will probably result in tougher competition between upper secondary schools.The purpose of this study is to review and compare financial and performance management between a public and an independent upper secondary school. The dissertation will focus on the now existing competitive relationship between the two types of upper secondary schools.The theory underlying the study is Porter's model - five competitive forces. The model is applied to the local upper secondary school and used to identify competitive factors affecting upper secondary schools. The study is using a qualitative approach with five interviews at two upper secondary schools, one independent and one public, located in the same town.The comparison of financial and operational management of upper secondary schools indicate that the differences are not as great as we first imagined, but that there still are some differences.

LEED i Sverige och i byggprojektet Borgarfjord 3.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

Skolbiblioteksforums verksamhet : - en fallstudie sett ur perspektivet den lärande organisationen

10 years ago the School Library Forum´s core activity started; the development of model libraries. Since then, no comprehensive study of the School Library Forum has been made. How does the organization actually work and how do professionals perceive the changes of the organization? Against this background, the purpose of my essay is to examine the activity of the organization School Library Forum with a focus on organization and learning from the viewpoint of the learning organization. The following issues have been helpful to meet the purpose of the study:? How do the business developer, the principals and the school librarians experience the collaboration on the school-libraries model-library activity?? How does the collaboration contribute to learning within the organization according to the business developer, the principals and the school librarians?? How do the business developer, the principals and the school librarians perceive the changes in the School Library Forum´s organization, seen from the perspective of the learning organization?By conducting five interviews with stakeholders in various positions within the organization, such as business developer, principals and school librarians, a deeper insight into how respondents perceive the business from the perspective of the learning organization is obtained.

"Hur fan kan man jobba som kriminalvårdare?": en studie i hur kriminalvårdare ser sin yrkesroll ur en psykosocial kontext

This analysis explores the psychosocial aspects in relationship to the occupational role as a correctional officer in Sweden. Historically prisons are hierarchically structured with a military organisation used as the basis for a role model. This military type structured organisation is designed to keep the prisoners under constant observation, thus providing direct authority and control by the prison guards over the prison inmates. Data obtained from investigations conducted by the Swedish Government indicate a direct link between the prisoners's living conditions and the prison employee's work duties and environment. The data strongly suggests that the work needs of prison guards have significant priority over the general work conditions of inmates, thus showing that the status for the occupational role was relatively low.

Att be om hjälp utan att fråga

This report is our Master thesis. Our work has taken place at a one-stop-shop in Sölvesborg during the spring of 2002. We have conducted ethnographical studies concerning the one-stop-shops frontdesk and telephone exchange. During these studies we became aware of some differences under which the daily work was to be carried out. When operating the switchboard the staff usually work alone and perform the tasks individually.

En myndighet i kraftig expansion - En kvalitativ studie om utmaningar med strategisk kompetensf?rs?rjning inom Kriminalv?rden

Purpose: The Swedish correctional service is on the brink of its biggest expansion in history, due to political investments related to battling a rise in gang related criminality. The purpose of this thesis is to exam and understand the strategic competence supply work from an employer perspective and investigate the elements included in the Swedish correctional service competence supply form a regional perspective. The study specifically focus on what strategies the Swedish correctional service employ to attract, recruit, develop and retain workforce. Theory: The theoretical framework of the study includes among others, a model divided into three different phases (within, in and out) within competence supply, the demand-control-support model, push and pull factors, as well as the two-factor theory. Method: This study has a qualitative approach with semi structured interview as its specific method. A total of seven interviews were conducted with personnel within the swedish correctional service. Results: The main challenges are related to recruitment, staff retention, support of managers, and the fact that many correctional officers do not have time to complete their training before leaving. The latter is particularly significant are of concern.

Är egenföretagande en riskfaktor för alkoholmissbruk?: en studie om egenföretagande och dess villkor kan vara riskfaktorer för alkoholmissbruk

The aim of this essay was to obtain an understanding about company owners thinking about the connection between having an own company, and the risks for an alcoholic abuse. The risk factor I was researching was stress, alcoholic culture, accessibility and rehabilitation.I have interviewed five owners of small companies, two women and three men, which represents four different kinds of branches. The theories I used in analysing the empirical findings where the theories of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and culture perspective.I have found that the main stress factors for company owners where the economical stress and great load of work. The stress was also related to the fact that company owners of small companies often were alone with all the responsibility and problems.Women did not use alcohol very often as a tool to reduce stress. If individuals were using alcohol to reduce their stress, it also had to deal with their ability of coping and also what channels they had for coping..

Diakonalt arbete : Svenska kyrkans sociala arbete

Social work in Sweden has historically been mostly done by the public sector andthe work has been regulated by law. In the last two decades, private and voluntaryactors have played an important role as providers of welfare state; one of theseplayers is the Swedish Church. The aim of this thesis has been to describe thework the deacons perform in the Swedish Church in a medium-sized municipalityin Sweden. To find out how much freedom of action the deacons themselves feelthat they have and if they feel that their work is influenced by the social work thatother performers are doing. In order to reach the goal, a qualitative approach wasused where seven deacons were interviewed.
