BEPS Action 8 : Finns förutsättningar för att de angivna målen uppfylls?

BEPS är ett projekt påkallat av G20 som bedrivs i OECD:s regi. Projektet syftar till att förhindra erosion av nationers skattebaser, på grund av upplägg där vinster genom koncerninterna transaktioner flyttas till länder med låg beskattning. Denna uppsats behandlar specifikt BEPS action 8, vilken rör interprissättning av immateriella tillgångar. Syftet med uppsatsen är att utreda om OECD:s rapport angående BEPS action 8 ger förutsättningarna för att uppfylla, de i rapporten angivna målen, samt vilka problem som kan påverka måluppfyllelsen. Målet med BEPS action 8 är att se till att internprissättning av immateriella tillgångar, inte används för att separera beskattningsbara inkomster från värdeskapande aktiviteter.Därmed fokuserar BEPS action 8 på att se till att utförande av funktioner, användande av tillgångar och risktagande kompenseras på ett korrekt sätt, då detta anses bidra till värdeskapande.

Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån

WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad.   Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Inkongruenta styrmodeller: En fallstudie av reparation och underhåll i ett industriföretag

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

Attityder till tvåspråkighet

Jag har i den här uppsatsen gjort en kontrastiv undersökning av tre tyskars attityder till tvåspråkighet. Utifrån min frågeställning har jag utgått ifrån huruvida tvåspråkighet har medfört en ökad lingvistisk medvetenhet samt hur informanternas positiva och negativa attityder ter sig till detta. Jag har även snuddat vid begreppet kultur och hur informanterna upplever att ?leva i två kulturer?. De tre tyskor som figurerar i denna undersökning har alla kommit till Sverige på ett sätt som de upplever som positivt.

Energieffektivisering i kommun

AbstractThe Municipality Council decided in 2010 to develop a comprehensive energy efficiency strategy with financial and methodological support from Energimyndigheten (The Swedish Energy Agency). The strategy should include 3 major parts: an inventory of the 2009 energy use defining the current situation, the 2014 and 2020 goals for energy use, and an action plan for goal achievements. According to Energimyndigheten, the strategy must include all municipal administration premises, vehicles, and all majority-owned companies (as Laholmshem, the municipal housing company).The report describes the inventory work in order to obtain the 2009 energy use and the sources of information used. The inventory values are used as the base year values for the 2014 and 2020 goals. The inventory showed that information about the vehicles is dispersed in the municipal administration and no clear structure exists with respect to mileage and fuels used.

Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter

Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.

 Solenergi En del i ett långsiktigt, hållbart byggande

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Livscykelanalys för koldioxidutsläpp från flerbostadshus

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
