Verifieringsplattform i SystemVerilog
Our task was to create a virtual test bench for verifying memory addresses in our commissioning body?s models. The purpose with the testbench was that it should be created in such a way that it would be easy to change the device under test without any major changes in the testbench.To solve the problem that the testbench had to be able to verify different devices we had to create a general enviroment for how the testbench had to be composed. By doing an analysis of which com-ponents that are usually included in a testbench and which components that were necessary in our project we came up with a generall enviroment for the testbench. Our result was a testbench with the follwing basic functions:* Read from a file that contains read and write operations to the Device Under Test (DUT).* Apply the stimulus to the device* Read the results from the device* Compare the results with wanted values* Generate a log file which contains information about the simulation result..
C-7/13 Skandiamålet : En analys av hur Skandiama?let pa?verkar art. 11 merva?rdesskattedirektivet anga?ende merva?rdesskattegrupper
In September 2014 the ECJ issued its decision in C-7/13 the Skandia case. The case con- cerned service transactions made between a main establishment in a third country and its Swedish branch. The branch was a member of a VAT group in Sweden. The ECJ estab- lished that the membership resulted in that the VAT group was considered as one taxable person which meant that the services was considered provided to the group itself and not the separate member. Therefore the transactions were deemed taxable.
Energieffektivisering och analysering av inomhusklimat genom simulering : IVT Värmepumpar, Tranås
Syftet med detta examensarbete har främst varit att förbättra inomhusklimatet i byggnaden Greenhouse, tillhörande företaget IVT Värmepumpar i Tranås. De anställda upplever problem med värme i byggnadens utbildningslokaler främst under sommarhalvåret. Tid har även lagts på att ta fram åtgärder som sänker byggnadens energianvändning i form av el och värme.Då examensarbetet utfördes under hösten användes ett simuleringsprogram för att få en bild av inomhusklimatet under sommarhalvåret. En modell av byggnaden byggdes upp i simulationsprogrammet, komplett med ventilations- och värmesystem.För att validera modellen som konstruerats utfördes flertalet mätningar under en veckas tid. Simuleringsmodellen kalibrerades sedan mot dessa mätningar för att efterlikna de verkliga förhållandena i så stor mån som möjligt.
Modellering och simulering av hydraulik för användning i hardware-in-the-loop
Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.
Uba?tar pa? djupdyk i svensk media : En kvalitativ textanalys av framsta?llningen av uba?tskra?nkningen i Stockholms ska?rga?rd a?r 2014 i svensk media.
The 17th October 2014 the Swedish Armed Forces (SwAF) introduced an intelligence operation in Stockholm archipelago after receiving credible observations regarding illegal underwater activities. Following the data collection and associated analysis it could be stated with certainty that a foreign submarine had violated the Swedish territorial waters. Media depend on SwAF to provide them with accurate information due to the confidentiality in these matters and the general area of investigation is therefore how the actions of the Swedish Armed Forces, in the submarine incident 2014, were portrayed in the Swedish media. Newspapers and blogs of defense policy represent the media and the thesis is based on the theories constructed by Graham Allison, the rational actor, organizational behavior and governmental politics. Furthermore, it is relevant to examine if there are any similarities or differences in how the submarine incident is illustrated, and what may be the reason for any possible occurrences.
Mellanrum
I den ha?r uppsatsen har vi underso?kt hur trottoarens materiella ut- formning pa?verkar uppkomsten av mellanrum. Mellanrum a?r ett ba?de tidsligt och rumsligt fenomen som kan uppsta? i ett dynamiskt publikt rum.
Vi har observerat fyra trottoarer inom Malmo?s stadska?rna och under- so?kt hur materiella faktorer pa? och vid trottoaren pa?verkar vilka aktivite- ter som a?ger rum pa? platsen.
Uppsatsens o?vergripande forskningsfra?ga a?r: Hur pa?verkar trottoa- rens materiella utformning uppkomsten av mellanrum?
Under observationerna har vi underso?kt: Vilka materiella egen- skaper finns pa? trottoaren och hur pa?verkar de den territoriella komplexi- teten? samt Vilka omgivande faktorer ger upphov till en territoriell kom- plexitet pa? trottoaren?
Syftet med uppsatsen a?r att lyfta fram trottoaren som ett viktigt pu- blikt rum da?r det ofo?rutsa?gbara kan ta plats.
Ett av uppsatsens nyckelbegrepp a?r territoriell komplexitet [Ka?r- rholm 2004, 2012] da? chansen att mellanrum uppsta?r a?r som sto?rst pa? plat- ser med ho?g territoriell komplexitet.
Va?ra teoretiska utga?ngspunkter utgo?rs av Mattias Ka?rrholms ter- ritorialitetsbegrepp [2004] och stabiliseringsprocesser [2012] samt Emma Nilssons diskussion kring materiell figur och rumskategorier [2010].
Kulturhistoriska sto?d har vi ha?mtat fra?n Anastasia Loukaitou- Sideris & Renia Ehrenfeucht [2009] som bland annat skildrar en va?xande privatisering och uto?kand kontroll av stadens publika rum.
En slutsats a?r att mellanrum kan liknas vid territoriell taktik och app- ropriation som sker pa? en plats da?r anva?ndandet av platsen inte sto?ds av den territoriella strategin..

Datorsimulering av gruvlastare för funktionell testning
I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..
Om hur en banks value at risk bäst skattas med expected shortfall
Bakgrund: Om VaR kan estimeras väl med hjälp av ES-metodik, kan man få bukt med VaR-måttets brist på sudadditivitet (vilken innebär dels praktiska problem vid utformning av finansiella organisationers limitstrukturer, dels teoretiska problem i enlighet med Artzner et al (1997, 1999)) samtidigt som man uppfyller det formella kravet på att rapportera sitt VaR på 99 %:snivån. Syfte: Att undersöka hur väl ES ? estimerat på olika konfidensnivåer och med olika metoder ? duger till att skatta en banks 99 %:s-VaR. Metod: Två ES-metoders och sex VaR-metoders förmåga ? både avseende frekvens (Kupiec-test) och oberoende (eget längsta-följd-test) ? att skatta 99 %:s-VaR utvärderas och jämförs.
Baskisk identitet - en studie av den baskiska nationalismens förändring.
The aim of this study is to analyze the change of Basque nationalism during the last ten years and discuss how the main nationalist party (PNV) tries to impose "we"- feelings and support for its cause. Theories of nationalism and national identity are used in the analysis.A textual analysis of PNV:s unofficial documents is discussed and compared with a discourse analysis of its official documents. Although the unofficial documents deal with similar view of basic political/territorial ambitions, language and identification, there are some differences in the latest documents regarding the view of who is defined as Basque and also to the detoriated relation to Spain. Although references are made to the regard that the Basque Country is for everyone, the persistence of emphasizing the uniqueness and myths of the Basque culture signals a different matter. The discourse analysis of the official documents supports this claim and although they contain an ambiguous relation to Spain it is clear that Basque nationalism has been radicalized.
Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem
In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.
GALS,Design och simulering för FPGA med VHDL
Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.
Modellbygge av mekaniksystem och riktmotorer i stridsvagn 122
This master thesis is one part of a project, called ?StabSim?, with the purpose to develop a simulation model for the align and stabilisation system in main battle tank 122. The origin of this project is that it should be possible to make control analysis without risking any hardware. Besides that it will be easy to change components in order to investigate the behaviour of the system. The report includes modelling of tower and weapon mechanics and also the modelling of the synchronous motors, which control these.
CFD beräkning på en jetmotorinstallation
Hawk Turbine AB tillverkar mindre jetmotorer som ofta används i små obemannade och radiostyrda flygplan. I flygplansmodellen Lockheed T-33 Shooting Star är motorn monterad inuti planet varför luften måste ledas ut till atmosfären. För bästa möjliga prestanda måste ejektorn och utblåsröret som leder luften dimensioneras efter motor och flyghastighet.En 3-dimensionell CAD modell av flygplanets installation skapades och därefter simulerats i en virtuell vindtunnel med hjälp av datorprogrammet SolidWorks Flow Simulation. Flera olika utblåsrör i varierande storlekar samt olika former har testats för att avgöra om ändringar kan förbättra prestandan ytterligare.Simulationsresultat visar att det går att förbättra nuvarande konfiguration med 5,99 % om diametern på utblåsröret minskas från 75 mm till 70 mm med en bibehållen form på utblåsröret..
Frosttolerans hos douglasgran av olika ursprung och tillväxttyp
This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.
