Scalable Services over DAB and DVB-T from a Receiver Point of View

TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.

Statistisk analys av barnpsykiatrisk symptomatologi som ökar risken för senare personlighetsstörning

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

Annonsmediers miljöpåverkan : när ska miljön få en reklampaus?

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

Användargränssnitt för tekniska system i distribuerad vård : behov och krav ur vårdgivarens perspektiv

Institutionen för medicinsk teknik vid Linköpings universitet var i behov av att utvärdera användbarheten på den prototyp som de tagit fram för mätning av fysiologiska parametrar i distribuerad vård. Syftet blev därför att genom att använda metoder så som heuristiska och summativa utvärderingar ta reda på vilka behov och krav som de tänkta användarna ställer på användargränssnitt som används inom distribuerad vård. För att kunna genomföra dessa metoder genomfördes studiebesök, användaranalys, fokusgrupper, kontextuell utforskning och en funktionsanalys. Resultatet av de två utvärderingarna visar att användarna ställer höga krav på den här typen av användargränssnitt, framförallt gällande säkerställande av identitet och anpassning till användarnas verklighet..

Strategi för IKT i skolan ? att integrera teknik i ett komplex sammanhang : Mätbart, jämlikt, statusfritt

Today there are many studies that have shown positive results in the treatment of ICT at an early age. The focus of the studies vary, and they target everything from the actual implementation of teaching resources in ICT, to student performance with ICT support. Regardless of the amount of studies on the subject, there is no precise strategy for how to implement, working with ICT, integrate ICT in different subjects, utilizing the hardware and software that is or how it will eventually respond to new technologies. This work will there by focusing on trying to develop a basis for further research and hopefully in the future to develop an ICT strategy at a national level.In order to provide a basis, a comparison was made of ten different schools. The schools were entered into a table showing the similarities and differences .

Ungdomsvåld : Ungdomars föreställningar om ungdomsvåld och dess orsaker

The purpose of this essay was to examine teenager's views on violence among young people.Our main questions were: What kind of views on violence among young people do teenager's have? What do teenager's think about what causes violence among young people? In what way does scientific knowledge confirm young people's views about what causes violence among young people?To answer these questions we designed a questionnaire which we distributed in three 8th grade classes. We also interviewed five teenagers about violence among young people, to get a deeper knowledge about their views.The results of this study show that the teenagers think that violence among young people has increased and that the violence mostly appears between different groups of young people. The teenagers also think violence among young people as a phenomena due to different kind of reasons..

Kanal 1 i Kanal5? : En kvantitativ studie om studenters attityder gentemot att public service utför marknadskommunikation

In recent years, the digitalization and media convergence has increased, which has made the market for public service- medias more competitive. Perhaps this is why public service has chosen to communicate with recipients outside their own channels.The purpose of this quantitative study is to find out how students attitudes looks towards the fact that public service are performing marketing communication. To find out, we conducted a survey, as 256 students of Linnaeus University in Kalmar answered. Together with the study we have used different theoretical references in order to analyse the responses from the survey, and obtain our conclusions.By analysing the empirical material we came to the conclusion that the majority are in favour of public service performing communication outside its own channels. But we also noticed that the communication needs to be in a certain way for the students to be positive.

Massundanträngning i samband med pålning i lera

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Lika bolag leka bäst - En studie om betydelsen av likhet vid sammanslagningar av bolag

This study addresses the issue of mergers between consulting firms. Previous research has shown that there are specific factors that determine the outcome of a merger and that success is more likely if companies are more similar. The purpose of the study is therefore to define relevant factors and understand when resemblance matter and under what conditions disparity may cause problems. Furthermore, the aim of the study is to find a pattern of which factors are more important in a successful merger. The problem of the study is addressed through a qualitative research approach and is conducted on six different mergers.

En utvärdering av två olika sa?tt att skatta fördelningen till stickprovsmedelvärden från olikfördelade data - normalapproximation kontra resampling

Papperslösa barns rättigheter

This case study examines how upper secondary schools in a municipality in the northern parts of Sweden structure their special pedagogy with students who have ADHD and dyslexia, students? and parents? experiences of this, and what regulates the schools management in this particular aspect. The results show that all the schools have special pedagogues and other support staff employed, though in varied extent. Furthermore, the resources are distributed differently from school to school. The focus, however, is always around communication between the concerned parties.

Processoperatörens mobilitet -teknikstöd för mobil larmhantering

Processindustrin har möjligheten att ta steget in i en ny utvecklingsfas där teknik kommer att spela stor roll. I och med att teknik allt mer stödjer mobilitet öppnas möjligheten för processoperatörer att på valfri plats kunna övervaka och styra tillverkningsprocessen. Med denna rapport presenterar författaren sin empiriska studie på en högteknologisk fabrik. Studiens fokus ligger i betydelsen av processoperatörernas mobilitet och hur den framträder i deras arbete. Studien visar att mobilitet för operatörerna på fabriken är en del av deras yrkesutövande och väsentlig för att kunna styra tillverkningsprocessen.

BORDTENNISSPELARES MÅLSÄTTNINGSPREFERENSER BEROENDE PÅ MÅLINRIKTNING

SammanfattningSyftet med studien var att studera skillnader i vilka mål bordtennisspelare använder sig av beroende på målinriktning. I studien deltog 103 bordtennisspelare (60 män och 43 kvinnor) tävlandes i division ett till tre. Metoden som användes i studien var en kvantitativ undersökning och bestod av enkäterna Collegiate Goal Setting in Sport Questionnaire (Weinberg, Burton, Yukelson, Weigand, 1993) och Task and Ego Orientation in Sport Questionnaire (Duda & Nicholls, 1992; ref i Duda, 1998). Resultatet i studien visade flera signifikanta skillnader mellan bordtennisspelarna med högre resultatinriktning och bordtennisspelare med en lägre resultatinriktning när det gäller uppfattning om målsättning. Resultatet visade exempelvis att bordtennisspelarna med högre resultatinriktning oftare satte resultatmål och prestationsmål jämfört med bordtennisspelare med en lägre resultatinriktning.

Nej, inte rita. Låna!: 3-4-åriga barns informationsbeteende på folkbibliotekets barnavdelning

The aim of this study was to examine how children in ages 3 to 4 use the public library with the research questions: What does children?s, in ages between 3 and 4, information behavior look like when they visit a public library in leisure time with a parent? What is the nature of interaction between child and parent, child and the staff of the library, and between child and other visitors? What is the function of the cultural tools in relation to the children?s information behavior? The theoretical frame of reference consisted of Lev Vygotsky?s ?the zone of proximal development? and Roger Säljö?s theory about using cultural tools. To answer the questions I have observed 4 children together with their mothers and siblings at a public library. From the result of the observations I found that every child had their own information behavior. Two of the children only used one kind of cultural tool ? books.
