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.

In the present study, the institutional discourse in health care was examined, focusing onspeech therapists and occupational therapists in interaction with a common patient withaphasia. The purpose of the present study was to identify common communication strategiesused in the professional conversation between a speech therapist and a patient and between anoccupational therapist and the same patient. Specific research questions were: Whatcommunicative strategies are used in interaction between a speech therapist and a patient withaphasia and between the occupational therapist and the same patient? Are theredifferences/similarities between how speech therapists and occupational therapists interactwith patients with aphasia?Six people in total, two patients in interaction with a speech therapist and an occupationaltherapist respectively, were recorded during treatment sessions of each profession. Generaland specific aspects of the institutional interaction were then analysed according to principlesof conversation analysis.Similarities in the use of closed questions as a strategy to increase the effectiveness ininteraction could be seen between the two different professions studied.

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.

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.

In this study I have investigated how role playing may change young students´ attitudes and behavior. According to the Swedish National Agency for Education´s governing document, Läroplanen för de frivilliga skolformerna, 1994, the principals at Swedish schools are required to inform students about the risks connected with alcohol and traffic. Scientists bring to our attention the need for emotional information to change attitudes and behaviors. The Historical Wine- and Sprits Museum in Stockholm has arranged a role play that gives emotional information to school students in order to affect their attitudes towards drunk driving. My study is a qualitative examination of this role play.

As used in this study, strategic documentshave the purpose of pointing out focus and strategic planning for an organization. Sixstrategic documents are chosen. The main theory and method used is critical discourseanalysis signed Norman Fairclough.

Tidigare studier har visat att bristen på strukturell empowerment på vårdavdelning ofta leder till försämrad personalhälsa, sämre arbetsmiljö och mindre samarbete med kollegor samt högre grad av utmattningssymtom. Syftet med studien var att beskriva vårdpersonalens upplevelse av strukturell empowerment vid en akut kirurg- och ortopedavdelning, samt att undersöka om det finns några skillnader mellan sjuksköterskors och undersköterskors skattning av strukturell empowerment. Ytterligare ett syfte var att beskriva vårdpersonalens upplevelse av arbetstillfredsställelse samt att reliabilitetstesta ett instrument som mäter strukturell empowerment. Data gällande strukturell empowerment samlades in med instrumentet Condition of Work Effectiveness Questionnaire (CWEQ och CWEQ II) och data gällande arbetstillfredsställelse samlades in med en studiespecifik fråga. Femtioen enkäter delades ut, 43 personer svarade vid första mätningen och 39 personer vid andra mätningen.

To challenge the competition within the construction business there are requirements ineffectiveness and use of operating computer based programs and work-methods. Thecomputer based programs are continuously improved and can at some point be the start of anew work-method. The work-method of tomorrow can be Building Information Modeling(BIM).This Master of Science Thesis gives an understanding in what BIM is and what therequirements for Sweco Theorells are in a future BIM-use as a consulting-firm. Theunderstanding is presented through a study of theory within the subject. The way of thinkingand acting among different disciplines and individuals within the building process isexplained through an interview study.The term BIM is regularly used.

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.

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.

Uppsatsen belyser vilka faktorer som påverkar om en utbyggnad av vattenkraft i Kalixälven är samhällsekonomiskt lönsamt med beaktande av olika näringar samt de eventuella miljöeffekter som uppstår. Teorin utgörs av centrala begrepp ifrån en cost-benefit kalkyl. Under arbetet med uppsatsen har ett tydligt mönster utkristalliserat vilket utmynnat i följande. De slutsatser som dragits av studien är fördelar som ökad elförsörjning, intäkter samt ökad sysselsättning. Förlorade forssträckor orsakar ekonomiska förluster på grund av minskad fisketurism och naturupplevelsen av en fritt strömmande fors, vilket också drabbar turister och fritidshusägare i omgivningen.

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"..

The Swedish healthcare system is characterized by lack of resources and extensive hospital queues. In order to counter these difficulties the Lund University Hospital have introduced Lean Healthcare to the hospital organization. The purpose of this scientific paper is to study the relationship between the implementation of Lean Healthcare and the experienced motivation among the staff. This essay thereby intends to impart knowledge, which could be used on future implementations of Lean Healthcare at other hospitals. In order to fulfil the purpose of this essay a case study have been conducted at two wards at the Lund University Hospital in which qualitative research interviews have been the method chosen in order to gather data.

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.

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.
