TV-rättigheter inom svensk idrott : En studie av det rättsliga läget rörande ägande av och skydd för TV-rättigheter inom svensk idrott
AimThe aim of this study is to investigate who can be considered to be the owner of the broadcasting rights on sport events in Sweden. Furthermore our aim is to investigate how the owners can protect their rights.The reason why we are interested in this subject is that there is no legislation in this field. There is no legislation on who the owner is and there are no arena rights that protect the broadcasting rights. We have studied case law and legislation in other countries and tried to apply it to Swedish conditions. We have posed the following questions:Who owns the broadcasting rights on sport events in Sweden?What legal protection does the owners of the broadcasting rights have for their rights?MethodThe study is based on literature studies and interviews.
Ekosystemtjänster av alley cropping i tempererade klimat : litteraturstudie
Den så kallade ?gröna revolutionen? inom jordbruket inleddes på 1960-talet och innebar högavkastande grödor, ett oreflekterat högt användande av kemiska bekämpningsmedel, samt intensiv bevattning och mekanisering. En underdrift är att påstå att detta skapat minst sagt stora problem för jordens ekosystem. Ett alternativ för hållbar matproduktion är agroforestry, som innebär produktion av träd på samma mark som produktion av jordbruksgrödor. Systemet är bland annat utvecklat för att förbättra ekologiska samspel.
Radon i flerbostadshus : Kartläggning av fastighetsförvaltarnas egenkontroll avseende radon
Radon is a hazardous substance that cannot be perceived by our senses. It has long been known that exposure to high radon levels for a long period of time will ultimately cause lung cancer. The Swedish Radiation Safety Authority estimates that 500 people die annually due to this. Although most of them are smokers, even non-smokers suffer from lung cancer caused by radon. The statutory value for radon in homes today is 200 Bq/m³.
Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner
The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.
Datorsimulering av gruvlastare för funktionell testning
I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..
Trafiksäkerhet inom ambulanssjukvården : Den operativa personalens syn på utryckningskörning
Att framföra ett utryckningsfordon skiljer sig från att framföra en vanlig bil bland annat för de större friheter gällande trafikregler utryckningsförarna har. Dessa inkluderar både rätten att köra i högre hastigheter än annan trafik, men även möjligheten att kräva fri väg från andra trafikanter. Detta skapar en speciell interaktion mellan trafikanterna i trafiken där utryckningsfordonet kan ses som en lagligt olaglig agent. Avsaknaden på restriktioner gör dock körningen helt beroende på de enskilda utryckningsförarnas bedömning kring körbeteende. Trots det finns det inga nationella riktlinjer i Sverige fällande utbildning av utryckningsförare.Den här studien undersökte normer och värderingar kring trafiksäkerhet hos operativ personal inom en ambulansorganisation.
Strategi för utvecklande av reglerbudata
This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.
Avlivning av sällskapsdjur, utförd av annan än veterinär : ett djurskyddsproblem?
We know that more than 2/3 of insured dogs in Sweden are put to death by a veterinarian, which means that almost one third are killed in trauma, lost or die in some other way. An unknown number of these are killed by their owner with no veterinarian involved. This graduate thesis contains a specification of the laws that control euthanasia of dogs and cats in Sweden, and the veterinary medical basics on how to perform euthanasia. The objective is also to give understanding on how pet owners choose to put their animal to death and why, and to discuss whether that is an animal welfare problem.
It is legal to kill dogs and cats by shooting, using a sporting gun, provided that it is done according to laws and regulations.
Sa?kerhet och integritet i webbapplikationer : En orientering o?ver sa?ker utveckling
The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
Vad har egentligen säkerhetskulturen för betydelse? : En flerfallsstudie på åkeriföretag
Från det välkända begreppet företagskultur har ett nytt begrepp vuxit fram, Säkerhetskultur. Detta kan ses som en förlängning på det tidigare begreppet där säkerheten ställs i rampljuset. Det sägs att åkeribranschen som helhet har en dålig säkerhetskultur samtidigt som ett bristfälligt säkerhetsbeteende är ett tecken på en högre skaderisk för företagen. Men vad har egentligen säkerhetskulturen för betydelse?Syftet med uppsatsen är att förklara hur säkerhetskulturen ser ut i åkeriföretag.För att kunna besvara syftet med uppsatsen har en kvalitativ flerfallsstudie genomförts, där de sex åkeriföretagen A till F har undersökts.
Anstaltens ambivalenta funktion : En studie av den samtida kriminalvårdsdiskursen
Due to the attention of several escapes, rescue attempts and hostage situations from Swedish prisons during the year of 2004 a debate about correctional system and safety arose. It resulted in official reports and proposals to improve the safety of the institutions. The incidents of 2004 will most likely have an effect on the discourse of the correctional system. The purpose with this study is to analyse which discourses that today can be distinguished in the correctional system and thereby will be the foundation of the correctional systemof tomorrow. The method used to answer the purpose of the study is a Foucauldian based discourse analysis.
DRM - utveckling, konflikter och framtid : konsumenters reaktioner på och företags användande av DRM
With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.
Att vinna musikmatchen: Hur skivbolag förblir framgångsrika i en strömmad värld
Music streaming services are changing the music industry from the inside. After being struck by the piracy wave in the early 2000's, the industry was characterized by declining sales, layoffs, and a seemingly futile battle on what had become a culture of copyright infringement. After the successful launch of the music streaming service Spotify, the Swedish recording industry took a turn for the better. Music streaming services are creating both new opportunities and challenges to the music industry. This paper aims to study some of the opportunities and challenges concerning the creation of new music.
Om hur en banks value at risk bäst skattas med expected shortfall
Bakgrund: Om VaR kan estimeras väl med hjälp av ES-metodik, kan man få bukt med VaR-måttets brist på sudadditivitet (vilken innebär dels praktiska problem vid utformning av finansiella organisationers limitstrukturer, dels teoretiska problem i enlighet med Artzner et al (1997, 1999)) samtidigt som man uppfyller det formella kravet på att rapportera sitt VaR på 99 %:snivån. Syfte: Att undersöka hur väl ES ? estimerat på olika konfidensnivåer och med olika metoder ? duger till att skatta en banks 99 %:s-VaR. Metod: Två ES-metoders och sex VaR-metoders förmåga ? både avseende frekvens (Kupiec-test) och oberoende (eget längsta-följd-test) ? att skatta 99 %:s-VaR utvärderas och jämförs.
