Vill du ha en snigel på ögat? : En kvantitativ undersökning om svensk public service-televisions innehåll över 34 års tid.
Our study shows if and how Swedish public service television has changed its content from the time when SVT had monopoly until this day when the competition is greater than ever. We got an insight in what has been presented to the audience by studying TV schedules from 1975 to 2009. The study examines four weeks during the years when the two main channels SVT1 and SVT2 have been broadcasting. One week each of these following years have been examined: 1975, 1985, 1995 and 2009. These years have been chosen to get an insight in what content the TV schedules presented before and after SVT got competition in the Swedish TV market.
Gallring av böcker på svenska folkbibliotek idag ? hur kan den se ut? Några exempel
The main purpose of this thesis is to investigate how books are weeded in some Swedish public libraries today. It tries to shed light on some of the problems and obstacles that may arise, and on the criteria used by staff for weeding. I also hope to build a model for weeding, based on the results of my investigation. The method I have chosen for my work is qualitative interviews. The results of my thesis indicate that weeding is not the top priority of the staff at the investigated libraries.
Feldetektering för diagnos med differentialgeometriska metoder -en implementering i Mathematica
Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.
Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning
An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.
Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Att prognostisera avverkningspotentialen i privatskogsbruket
For the actors in the Swedish forest industry, it is important to have the ability to forecast the state in the privateforests. The information that comes out of the forecasts will be the base for the activities strategic direction.The aim in this exam is to survey what information that is present today as basis for forecast calculation, andeven to examine what other possibilities it might have in the future.From a limited geography and out of different time perspective forecast the felling potential in the privateforestry.With the word felling potential means regeneration felling and thinning. The exam will answer the questions:What information is needed to build a relevant forecast model?Is this information available today?Is there information to buy that would improve the forecast model?The result of this exam will be presented in form of a ”case study” showing the opportunities in the market tocreate a forecast calculation of felling potential in the private forestry within the Forest Owners’ AssociationMellanskogs wood-area Dalarna..
Fuktskydd och planering i byggprojekt ? Erfarenheter från Eolshäll
When the Eolshällproject was completed for the first time, a great deal of moisturedamage was discovered. Therefore the structure completion was removed andreinstalled. The project was originally planned to cost a total of 126 million SEK, but thefinal costs landed on 271 million SEK. What caused this failure? Were the designs poor,was the technology used too advanced, or was the project not managed properly?Based on the Eolshällproject, theses will be presented about what may have caused themoisture damage.
Debatten kring Patriot Act. American Library Association's och den amerikanska regeringens förhållningssätt till anti-terrorismlagen The USA Patriot Act of 2001
This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.
På tu man hand : Pedagogers uppfattningar kring arbetet med elever i behov av särskilt stöd
The purpose of this essay is to describe the organization of the Swedish Animal WelfareAgency during the time it was in operation. The Swedish Animal Welfare Agency was established in 2005 by the government who saw it as necessary in order to strengthen the protection of cruelty to animals in Sweden. However, the agency was shut down already in2007 and its responsibilities as an agency was moved back to the government and the department of agriculture. During its time in operation, the Swedish Animal Welfare Agency, received much criticism, among other things because of its interpretations of the law which were seen as too focused on details and thus ?bureaucratic?.
Afghanistans demokratiseringsprocess : En kvalitativ fallstudie om förutsättningarna för att lyckas med konsociationell demokrati i ett av världens fattigaste länder.
This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..
Prövning av liggtidssensorer som indikator på förestående kalvning hos dikor
The aim of the study was to find repetitive behavioral patterns pre calving that could be used as indications of calving in beef cattle. In the study sixteen Standing- and lying down sensors were attached to the leg of sixteen beef cows. Ten of the sixteen beef cows gave birth to calves during the trial period. From these ten cows, data from six cows were used to assess the sensors fitness for use as calving indicators. The analytical part of the experiment was divided into two parts, calculation of divergence of mean lying time within different time intervals, and the number of lying bouts.The first part consisted of optimization of an equation used to highlight divergence in mean lying time within eight different time intervals (3, 6, 9, 12, 15, 18, 21 and 24 hours).

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122
This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..
