The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.
En algoritm för linjära optimeringsproblem
Denna uppsats behandlar en algoritm som löser linjära optimeringsproblem. Algoritmen bygger på en liknande idé som simplexalgoritmen men i denna kan startvärdet även vara en punkt inom tillåtet område eller på randen till detta område. Det behöver inte nödvändigtvis vara en hörnpunkt, vilket simplexalgoritmen kräver. Under algoritmens gång kommer iterationsvärdena att ligga på randen till det tillåtna området för att slutligen hamna i ett hörn. Därefter går iterationsvärdena från hörn till hörn tills slutligen optimum har nåtts.
Distributionsekonomisk optimering av dagligvaruhandelns lokalisering : förstudie till ett forskningsprojekt
The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

?Ärligt talat så har det [tradingen] blivit en skitaffär? : En fallstudie av HQ Bank
The global financial crisis hit hard on banking operations worldwide and the sector fell under considerable scrutiny, with particular criticism directed against the banks' own trading practices. A bank owned by the Swedish financial corporation HQ seemed to go without serious financial damage duringthe crisis.In 2008 Finansinspektionen began a review of HQ's activities and a number of shortcomings were identified. Among other things, HQ's risk management was questioned by Finansinspektionen and further how this potentially affected the valuation of complex financial products.In our paper we have chosen to highlight both national and international laws and guidelines that HQ used for their operations and study if HQ followed those laws and guidelines. We also want topresent the theoretical model used by HQ for the valuation of its European options and how HQ calculated their capital requirements ratio. Our purpose is to show how the valuation affected the capitalrequirement ratio and whether HQ followed the necessary laws and guidelines for the valuation of complex financial products.We have chosen to carry out a case study from a deductive approach.
Svartlistat ? en kvantitativ studie om tobak-, vapen-, alkohol- och spelrelaterade aktier som bojkottas av etiska fonder.
Syfte: Uppsatsens syfte är att med hjälp av kvantitativa analyser påvisa eventuella positiva eller negativa skillnader för investeringar i aktier inom de av etiska fonder bannlysta branscherna tobak, vapen, alkohol och spel jämfört med andra mer politiskt korrekta sådana. Studien vill också belysa huruvida aktier inom dessa fyra branscher kan uppvisa någon signifikant användbarhet i aktieportföljer, vilken i förekommande fall skulle utgöra ett investeringsmässigt handikapp för de etiska fonderna. Metod: Studiens genomförande bestod främst i att med hjälp av ett antal databaser samla in en stor mängd data för att därefter behandla desamma utifrån vedertagna matematiska metoder. Resultaten analyserades därefter med hjälp av nationalekonomiska teorier utifrån den teoretiska referensram som uppsatsen grundar sig på.Slutsatser: Sammantaget visar studien att de i uppsatsen konstruerade oetiska aktieindexen inte kan uteslutas ur en portfölj utan att märkbar förlust uppstår. Den visar också att de oetiska indexen måste ses som mycket intressanta investeringsobjekt såväl individuellt som ur ett portföljperspektiv.
Algebraförståelse ur elevers och lärares perspektiv
Bakgrunden till studien är att forskningen visar att elever i svårigheter utvecklas mest kunskapsmässigt och mår bäst socialt av att inkluderas i klassens undervisning. Trots detta finns det väldigt ofta en önskan att exkludera dessa elever eftersom många lärare inte anser sig klara elever med specialpedagogiska behov inom den ordinarie undervisningens ram. Detta har lett till en rättvise- och inkluderingsdebatt såväl som en debatt med ekonomiska förtecken. Frågor som lyfts är ?Var mår eleverna bäst och finns det metoder som fungerar så att alla elever kan inkluderas?? Min studie syftar till att undersöka möjligheten till ett inkluderande arbetssätt i engelskundervisningen med hjälp av Europeisk Språk Portfolio och Autonomous Learning.

Efficiency and optimization in the logisticsat company Dagab
This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.
Sharpekvoten utvärderad medelst stokastisk dominans
Syfte: Att utröna om det kan förkastas att Sharpekvoten ger en utvärdering av fonders prestation som stämmer överens med investerares förmodade uppfattning om nytta, dels för vanliga fonder, dels för hedgefonder. Teoretiska perspektiv: Sharpekvoten bygger på antagandet att investerare bedömer investeringar utifrån förväntad avkastning och varians. För att så ska vara fallet krävs att någon av följande förutsättningar är uppfyllda: att investeraren har en kvadratisk nyttofunktion eller att investeringars avkastning är normalfördelade. Det finns fog att ifrågasätta huruvida någon av dessa förutsättningar är uppfyllda (främst för hegdefonder) vilket innebär att fog även finnes för att ifrågasätta Sharpekvotens tillförlitlighet. Stokastisk dominans är en metod som tar hänsyn till hela avkastningens fördelning, och bygger på mycket rimliga antaganden om investerares nyttofunktioner.

Test-retest reliabiliteten i balanstesterna Unilateral stance, Limits of stability och Rhythmic weight shift
Människans balanssystem kan beskrivas utifrån tre delkomponenter, det vestibulära, det visuella och det somatosensoriska systemet. En rad olika skador och sjukdomar som påverkar dessa system stör därmed också balansen. Balansstörningar kan verifieras med hjälp av funktionella tester eller teknisk utrustning. Då teknisk utrustning används är det vanligt att instrument utnyttjas med kraftplattor i syfte att mäta det posturala svajet hos patienterna. Vid balansutvärdering är det viktigt att de instrument som används är validitets och reliabilitetstestade.
Analys av sorptiv kylning i industri- och kontorsbyggnader
Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.
