Kostnadsoptimering av singelfrekvensnät för marksänd
digital-tv med Simulated Annealing
I det här arbetet har algoritmen Simulated Annealing undersökts med avseende på dess möjlig att användas för att minimera av kostnaden för ett singelfrekvensnät för digital tv. Undersökningen är gjord genom att simulera ett antal testfall för att utreda hur olika ingående optimeringsparametrar inverkar på slutresultatet. Alla försök har genomförts i ett egenkonstruerat simuleringsverktyg, gjort i Matlab. En jämförelse av resultaten för två olika sätt att hantera täckningskraven har också gjorts, Simulated Annealing med- respektive utan straff metod. Alla genomförda försök har genererat en betydande kostnadssänkning jämfört med startkonfigurationen.
Andrafiering eller integration Att särskilja för rättvisans skull?
This paper deals with Will Kymlicka's and Charles Taylor's theories of multiculturalism, and the criticism of these theories by Jürgen Habermas and Seyla Benhabib. It also gives a brief background to the Swedish integration and minority policies and places them in relations to the academic discussion. Taylor advocates cultural survival to be a legitimate policy objective and Kymlicka argues that rights should be diversified in order to adapt to different needs of cultural minorities. The thesis aims to confront the theories with interviews of four persons who voluntarily or by profession work for the interest of minorities. The theories have been operationalized as questions and structured in four themes with the purpose of analyzing the interviews.
Påbyggnad av våningsplan medlättkonstruktion : En jämförelse av stommaterialen trä ochtunnplåt
The purpose of this thesis is to examinethe possibilities for adding a floor to anexisting building using the two materialswood and sheet metal profiles as the loadbearing structure. An apartment buildingfrom the 60s has been used as referencehouse. Two different suggestions for thedesign are presented in the rapport. Oneof them has been analyzed with wood andsheet metal as the load bearing structure.Using the old constructional calculationsand blueprints of the existing buildings,the load bearing capacity has beencalculated. In the calculation programFEM-Design the building has been testedwith the loads that an extra floor wouldgive.
Barns berättande och återberättande : En jämförande studie mellan enspråkiga och flerspråkiga barn i Sverige
I dagens globaliserade samhälle blir det allt vanligare att barn växer upp med fler än ettspråk i sin omgivning. Det kräver en ökad kunskap om flerspråkighet och vad somsärskiljer flerspråkiga barn från enspråkiga barn. Då de mätinstrument som idaganvänds i Sverige för att utröna om ett barn har en språkstörning endast är utformade förenspråkiga barn riskerar flerspråkiga barn att över- eller underdiagnostiseras. För attråda bot på den problematik som uppkommit i samband med diagnostisering avflerspråkiga barn och språkstörning har ett europeiskt forskningsnätverk bildats, kallatCOST Action IS0804. Syftet med nätverket är att kartlägga SLI (specific languageimpairment) hos flerspråkiga barn genom att koordinera forskning inom lingvistisk ochkognitiv förmåga över ett stort antal länder.
Läxor ur tre perspektiv - Lärarens, Förälderns och Elevens berättelser om läxor.
The workplace has a direct impact on the physical, psychological, economic and social well-being of the workers. A healthy workplace leads to increased health among the employees which also makes the employees more productive (Källestål, 2004). A poor working environment can have negative consequences for individuals, companies and society (SOU, 2009:47).This is a qualitative study that investigates companies? view of health promotion and how they practice health promotion in working life. Five private and five public companies, with representatives from the management were interviewed.
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
Kontrollerad verksamhet? Vilka faktorer påverkar utformningen av intern kontroll i kommunal verksamhet?
The purpose of this essay is to examine which factors that influence the design of internal control in municipal context and how well it works. We choose seven municipals, where we interviewed the administrative managers, the chairmen of the committees and two persons of the staff in each activity unit. The interviews were performed by telephone, due to the keeping of the essay?s timeframe.The theory in our essay comprises eight hypotheses. These hypotheses were operationalised into different variables aiming to make statistical tests possible.
Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.
Rökfri vid strålbehandling : Utvärdering av rökavvänjning vid onkologklinikens strålbehandling, Länssjukhuset Ryhov
The purpose of this study was to evaluate the support program, given to cancer patients in order to promote their own efforts to quit smoking and to study if they kept their changed cigarette consumption 6-18 months after their cancer treatment was done.Method: We have used a descriptive qualitative method with semistructured interviews which were made in the spring of 2010 at Uppsala University. The informants in this study were smoking cancer patients which had been given radiotherapy at the oncology department at Ryhov hospital in Jönköping, Sweden.The results showed that three out of eleven informants were still not smoking after their treatment ended. All informants agreed that information about the effects of smoking on their radiotherapy were important.This study also showed that there are areas in which the support program could benefit from being changed. Of those informants who did not succeed in their efforts to quit smoking, many felt that the support should have been more direct in the sense that the staff should have followed up on their progress more frequently. These unsuccessful informants also stressed that the location for where the information was given could have been more private.

Religionskunskap - Ett ämne i tiden? : En studie av kristendomens roll i ämnet religionskunskap
Before the autumn term 2011 the Swedish compulsory school adopted new syllabuses in relation to, inter alia, religion. Changes within the religion topic have historically been a heavily debated issue among decision-makers, interest groups and the church, where the role of the Christianity has been particularly controversial.The main purpose of this study is therefore to investigate how the Swedish compulsory school?s teaching of Christianity has changed over the years. I have in order to conduct this study applied a descriptive method as well as a content analysis. The Swedish compulsory school?s current and historical syllabuses in religion have served as basis for this study.The outcome of this study clearly shows that the Christianity has received less influence to the benefit of other topics.
Individanpassningens ytterligheter : Några betygsmässigt hög- respektive lågpresterande gymnasieelevers åsikter kring engelskundervisningens utformning.
In today?s society there is a discussion regarding students? level of knowledge and personalisation. The classrooms consist of heterogenic groups of students with different learning needs and levels of knowledge. The purpose of the present study is to find out how the students who participated perceive the teaching of English as an additional language with regards to personalisation, and how they believe differentiation can help develop and deepen their learning. This study has been conducted using a qualitative method with interviews as the core, complemented by observations. The results have been analysed and interpreted hermeneutically. The results show that those students who have a positive attitude to English education, irrespective of their grade, are those who see the benefit of knowing English outside the classroom, and thereby create a connection between reality and studying English.
Konstruktivt med konst: Hur Konstbiblioteket tillhandahåller tidningsartiklar och hur därmed sammanhängande problem kan lösas
The Art Library uses the newspaper cuttings archive to provide her customers with newspaperarticles about art. This archive has the following problems; there is little space left inthe paternoster lifts, the articles can only be found on keyword and to maintain the archive,much labour is required.This research aims to find out how the Art Library can provide her customers with newspaperarticles which will cost as little as possible.Six possible solutions are given. Out of these the solution with "Artikel-sok" was recommended.According to this solution the Art Library should no longer maintain the archive, butuse "Artikel-sok", a database from Bibliotekstjänst which contains descriptions of articlesfrom many Swedish newspapers and magazines. These articles can be ordered from Bibliotekstjänst.The old newspaper cuttings archive will be used for articles from before 1979,because these are not being taken up in the "Artikel-sok"..
Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp
In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.
The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness
In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production.
The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.
