Vindkraft och elbilar på Öland år 2020 : Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?

The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

"Det är svårt att få dem att stanna längre än tre år" : måste rekryteringsprocessen förändras för att tillfredsställa unga medarbetares krav?

How does a corporation work during the recruitment phase to entice and motivate younger members to work for their organization?The aim is to examine in which grade corporations and organizations? recruitment needs to adapt to encounter Generation Y on the labour market.The base in our method is abduction and our research is based on a qualitative method. We have fulfilled interviews with corporations such as Scania, Skatteverket, Swedbank and Appelqvist & Ottoson HR AB.Corporations need in a sense change their recruitment and emphasis their resources to sell the whole corporation and its image to the young job applicant. The younger members demand a total impression of the corporation to implement an interest and to get motivated to work there. Together with our respondents we have realized that Generation Y has higher demands on their workplace than earlier generations..

Den nya versionen består av en tunnare våg och en mobilapplikation, istället för en våg och en bärbar dator. Det finns ingen tidigare studie kring den nya versionens användarvänlighet.

Generationsmotivation? En kvantitativ studie om generationsspecifika motivationsfaktorers vara eller icke vara i arbetslivet

Följande studie är en personalvetenskaplig uppsats som behandlargenerationsspecifika motivationsfaktorer. Syftet med studien är att undersöka huruvidatillhörigheten till en särskild generation medför ett specifikt förhållningssätt till det egna arbetet, dvs. om några skillnader existerar generationerna emellan. Med hjälp av en undersökning utifrån en svensk kontext är vår förhoppning att genom vår studie kunna tillföra utökade kunskaper inom området.Teorin som uppsatsen baseras på berör tre huvudsakliga områden; motivation, generation samt en sammanslagning av de två begreppen. Motivationsbegreppet sett ur ett allmänmänskligt perspektiv är omfångsrikt och definierat på ett flertal olika vis, men saknar täckning för mer specifika kontexter.

Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser

District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.

LAN-Uppgradering

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.

Regler är till för att brytas

A purchase decision can be seen as a multifaceted context that raises many unanswered questions. Understanding the consumer's evaluation of alternatives is complex and should be studied at a deeper rather than wider scale. There is a problem for retailers to understand how the consumer manages a purchase decision in a retail setting with durables goods that generates a higher effort. The aim is to describe the decision rules used by the consumer and how they are expressed in this context. A better understanding of which ones they use and how they are conveyed will help retailers to create effective marketing solutions that generate positive outcomes as increased profitability and customer satisfaction.

Från generation till generation: generationsskiftesplanering i familjeföretag

Småföretag har stor betydelse för det svenska näringslivet och många av dessa företag är familjeföretag. En av familjeföretags största utmaningar är planering inför generationsskifte. Många företagare drar sig dock för att planera, eftersom överlåtaren måste ge upp sin makt och kontroll över företaget och därmed kan känna att han/hon ger upp sin identitet. Syftet med examensarbetet var att, med hjälp av ett praktiskt exempel, förklara planeringsprocessen inför ett familjeföretags generationsskifte, samt att ge rekommendationer för vad företag bör tänka på inför generationsskifte. En fallstudie med personliga intervjuer och en telefonintervju valdes som datainsamlingsmetod och till studieobjekt valdes ett familjeföretag som varit med om två generationsskiften.

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Planeringens sociala effekter : En studie av hur den fysiska miljön återspeglar de politiska visionerna i stadsplaneringen

This essay examines a presupposed correlation between the way one look upon values and the way one look upon the will of the people in a theoretical democratic context. The more specific purpose is to test the following hypothesis: There is a reversed connection between the way one look upon values and the way one look upon the will of the people in a theoretical democratic context, that is; a strong claim of values give reason to a limited conception of the will of the people and a weak claim of values gives reason for a more unlimited conception of the will of the people.In order to test the hypothesis I examine three different conceptions of democracy, these are: pluralist democracy, deliberative democracy and constitutional democracy. I analyze the way they look upon values, there view of the will of the people and finally if there is a connection between the way they look upon values and the will of the people. Values should be understood in a metaethical context. In other words it is not values in the ?common? meaning, instead its how val-ues in them selves should be understood, and even more relevant, what we mean when we ex-press values.My conclusions are, first and foremost, that there is a correlation between the will of the people and values, according to the formulation of the hypothesis.

Rederiers hantering av nya miljökrav : En studie om Birka Cruises, Tallink Silja och Viking Lines arbete med ekonomisk och miljömässig hållbar utveckling

The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.

Rumsbaserad bangenerering : En jämförelse av procedurella tekniker

Procedural Content Generation innebär att spelinnehåll genereras automatiskt för att dels minska arbetsbelastningen hos designers men också för att öka variationen i spel. Ett användningsområde för detta är rumsbaserad bangenerering där banor byggs upp av fördefinierade rum. Målet med det här arbetet var att implementera och jämföra tre olika algoritmer som kan åstadkomma detta; Binary Space Partitioning, Shortest path och en evolutionär algoritm. De kriterier som algoritmerna utvärderades på var tidseffektivitet, variation och möjligheten att nå alla rum. Resultatet visade att Binary Space Partitioning och Shortest path var de två algoritmer som var bäst lämpade att användas i ett spel där genereringen ska ske under körtiden.
