Syftet med detta examensarbete har varit att få en större kunskap om den musikaliska gestaltningen av karaktärer i film, samt att få en utökad kunskap om filmmusik generellt. Uppsatsen inleds med en kort skildring av filmmusikens historia samt en redogörelse för den tidigare forskning som berör ämnet. Därefter har en funktionell analysmetod, baserad i en kategorisering av filmmusikens olika berättarfunktioner, presenterats. Analysen är grundad i två frågeställningar och dess syfte har varit att ta reda på musikens narrativa funktion i film och de eventuella mönster som kunnat urskiljas i det musikaliska berättandet. Fyra olika scener ur fyra filmer har analyserats, alla med den gemensamma nämnaren att de gestaltar ett eller flera mord.Vidare har analysen sammanfattats. De musikala mönster som har lyfts fram för vidare diskussion är: Den ljudande intensiteten, Återkommande musikala element och Den musikala dynamikens utlösningspunkter.I diskussionen fastslås att de mönster som kunnat urskiljas härrör till den övergripande förståelsen av musikens funktion i film. Samt att grunden i det ljudliga berättandet ligger i dess förhållande till bildspråket och den aktuella filmens handling.

A series of measurements on the performance of solar cell string modules with low-concentrating CPC reflectors with a concentration factor C ˜ 4X have been carried out. To minimise the reduction in efficiency due to high cell temperatures, the modules were cooled. Four different way of cooling were tested:1) The thermal mass of the module was increased, 2) passive air cooling was used by introducing a small air gap between the module and the reflector, 3) the PV cells were cooled by a large cooling fin, 4) the module was actively cooled by circulating cold water on the back. The best performance was given with the actively cooled PV module which gave 2,2 times the output from a reference module while for the output from the module with a cooling fin the value was 1,8.Active cooling is also interesting due to the possibility of co-generation of thermal and electrical energy which is discussed in the paper. Simulations, based on climate data from Stockholm, latitude 59.4°N, show that there are good prospects for producing useful temperatures of the cooling fluid with only a slightly reduced performance of the electrical fraction of the PV thermal hybrid system.

PV-Wind-Hybrid systems for stand-alone applications have the potential to be more cost efficient compared to PV-alone systems. The two energy sources can, to some extent, compensate each others minima. The combination of solar and wind should be especially favorable for locations at high latitudes such as Sweden with a very uneven distribution of solar radiation during the year. In this article PV-Wind-Hybrid systems have been studied for 11 locations in Sweden. These systems supply the household electricity for single family houses. The aim was to evaluate the system costs, the cost of energy generated by the PV-Wind-Hybrid systems, the effect of the load size and to what extent the combination of these two energy sources can reduce the costs compared to a PV-alone system. The study has been performed with the simulation tool HOMER developed by the National Renewable Energy Laboratory (NREL) for techno-economical feasibility studies of hybrid systems. The results from HOMER show that the net present costs (NPC) for a hybrid system designed for an annual load of 6000 kWh with a capacity shortage of 10% will vary between $48,000 and $87,000. Sizing the system for a load of 1800 kWh/year will give a NPC of $17,000 for the best and $33,000 for the worst location. PV-Wind-Hybrid systems are for all locations more cost effective compared to PV-alone systems. Using a Hybrid system is reducing the NPC for Borlänge by 36% and for Lund by 64%. The cost per kWh electricity varies between $1.4 for the worst location and $0.9 for the best location if a PV-Wind-Hybrid system is used.

A one year data analysis for a micro PV-Wind hybrid system (0.52 kW + 1 kW), installed in Borlänge/Sweden is presented in this paper. The system performance was evaluated according the guidelines of the IEC 61724 standard. The parameters obtained allow a comparison with similar systems. The measurement data are also used to evaluate the sizing and operation of the hybrid system. In addition, the system was modelled in HOMER to study sizing options.

Filmmediet idag är den mest populära formen av masskultur. Med sin världstäckande genomslagskraft och sitt stereotypa porträtterande av verklighet, påverkar filmen världsåskådningen för människor runtom i världen. Ett brinnande ämne i amerikansk film har alltid varit Ryssland, på grund av de politiska motsättningarna och den historiska rivaliteten med USA. Studiens syfte är att undersöka hur Ryssland porträtteras i amerikanska filmer från perioden för presidenterna Dmitrij Medvedevs respektive Barack Obamas första mandatperiod. Frågeställningen för uppsatsen är: hur ser stereotypa föreställningar om Ryssland ut i amerikansk film 2008-2011? Trettiotal filmer med ryska motiv valdes ut för undersökningen och analyserades utifrån de visuella och sociala aspekterna. Resultatet visar på att det förekommer tre skikt av stereotyper om Ryssland: de eviga, som har existerat i hundratals år och spridits av resenärer; stereotyper från epoken för det kalla kriget; och stereotyper om det moderna Ryssland inspirerade av medias nyhetsrapporteringar.

Syftet med denna uppsats är att jämföra boken The Hunger Games (2008) av Suzanne Collins med filmen The Hunger Games (2012) regisserad av Gary Ross och försöka ta reda på vilken sorts adaption som är gjord. Jag arbetar med boken och filmen The Hunger Games var för sig för att eventuella skillnader ska framträda tydligare vad gäller karaktärer och miljöbeskrivning. När jag gått in på djupet och jämfört boken The Hunger Games med filmen märker jag vad som är förändrat. Till exempel saknas vissa karaktärer och scener i boken i filmversionen, medan andra scener har lagts till i filmen. Samtidigt är det förståeligt att en del måste göras om och tas bort för att en bok på flera hundra sidor ska kunna visas i en film på cirka två timmar. Tillägg, borttagna avsnitt och ändringar kan vara till både fördel och nackdel.

In April 2011 a monitoring system was installed to enable studies of the performance and the usage of a micro PV-Diesel Hybrid system at the Ihushi Development Center (IDC) near Mwanza in Tanzania. Estimations of the load have been obtained by a survey of installed appliances and interviews with users of installed equipment. The load profile obtained by measurements has been analyzed and compared to estimations of the energy use. Further, the system size and performance were studied.

This thesis is about new digital moving image recording technologies and how they augment the distribution of creativity and the flexibility in moving image production systems, but also impose constraints on how images flow through the production system. The central concept developed in this thesis is ‘creative space’ which links quality and efficiency in moving image production to time for creative work, capacity of digital tools, user skills and the constitution of digital moving image material. The empirical evidence of this thesis is primarily based on semi-structured interviews conducted with Swedish film and TV production representatives.This thesis highlights the importance of pre-production technical planning and proposes a design management support tool (MI-FLOW) as a way to leverage functional workflows that is a prerequisite for efficient and cost effective moving image production.

The starting point for this work was a discussion between my supervisor and myself during my teaching training. The discussion concerned the appropriateness of allowing students make films with sexual content. Film gives young people the opportunity to express their feelings and broaden their views. If the film then disseminates to unknown people via in-ternet, which it most likely will do, maybe it is no longer so positive. The aim of this study is to shed light on various aspects of identity and ethics that are important to keep in mind when young people in school make films. These aspects are to avoid making young people vulnerable to abuse and improper influence. One aim is also to highlight the advantages of making films in school. The study is inspired by hermeneutic interpretive and based on qualitative interviews. The informants are four students at the age of 18-19 at two different schools in one municipality in Sweden.The results of the study show that it is important for the informants that the films are pro-duced in an aesthetically good way so that it appeals to the audience. Two of the infor-mants have a specific audience and make more conscious choices, so that the audience will understand what is said. The study shows that the more a filmmaker considers the audi-ence, the more consciously he or she uses film as communication. To get positive feedback is important, but it is mostly friends of the filmmakers that actually comment. To get nega-tive comments is regarded as a disadvantage when placing material on the internet. Howev-er, none of the informants in the study have received negative comments on what has been posted. The opinions about what the informants believe is inappropriate to post on inter-net or to make films about regards sexuality and violations. Earlier studies show that mate-rial can, because it is interesting to other people, become widespread. For this reason it is important for teachers to have conversations with students about their preferences and opinions on various issues. Adults need to interfere in the young people's world, while be-ing open to their opinions. Then the young people's value system will be built up and give them a safe tool that helps them to avoid improper influence.

Denna kandidatuppsats avhandlar tre stycken analyser av tre stycken filmscener från filmerna A Clockwork Orange, Reservoir Dogs och Watchmen, tre stycken exempel på scener där så kallad anempathetic music används. Denna form av musik kan beskrivas som att den distanserar sig från vad som händer i den rörliga bilden genom att förmedla den motsatta känslan, till exempel om musiken är glad och lättsam medan en våldtäkt sker i bild. Denna uppsats analyserar i dessa tre analysexempel vad sådan filmmusik kan bidra med för berättarfunktioner och meningspotential i filmexemplens narrativ. Resultaten från analysen visade på att musiken i de tre valda analysexemplen bidrar till ökad reflektion hos publiken och hur detta möjliggör för att anempathetic music kan ses som empathetic mot publiken och deras tolkning av filmscenernas narrativ.

The Intelligent Algorithm is designed for theusing a Battery source. The main function is to automate the Hybrid System through anintelligent Algorithm so that it takes the decision according to the environmental conditionsfor utilizing the Photovoltaic/Solar Energy and in the absence of this, Fuel Cell energy isused. To enhance the performance of the Fuel Cell and Photovoltaic Cell we used batterybank which acts like a buffer and supply the current continuous to the load. To develop the main System whlogic based controller was used. Fuzzy Logic based controller used to develop this system,because they are chosen to be feasible for both controlling the decision process and predictingthe availability of the available energy on the basis of current Photovoltaic and Battery conditions. The Intelligent Algorithm is designed to optimize the performance of the system and to selectthe best available energy source(s) in regard of the input parameters. The enhance function of these Intelligent Controller is to predict the use of available energy resources and turn on thatparticular source for efficient energy utilization. A fuzzy controller was chosen to take thedecisions for the efficient energy utilization from the given resources. The fuzzy logic basedcontroller is designed in the Matlab-Simulink environment. Initially, the fuzzy based ruleswere built. Then MATLAB based simulation system was designed and implemented. Thenthis whole proposed model is simulated and tested for the accuracy of design and performanceof the system.
