This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

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.

This thesis aim to investigate the living conditions among marginalized habitants of suburbs in the Swedish welfare state. To approach an understanding of the complexity of marginalized urban areas, this thesis focus on studying the Stockholm suburb Husby in a context of the May riots 2013.The research method used is qualitative interviews with seven informants, who have a connection to the Husby area.The theories applied to the empirical material is Gösta Esping-Andersens theory on welfare state regimes and Loïc Wacquants theory on advanced marginality, also known as ?The new urban poverty?.By observing the complexity of the Husby riots in a contextual aspect of the Swedish welfare state and the living situation in Husby, the analysis has shown that the Swedish welfare model is going through a changing process. This process means a shift from a social democratic welfare model towards a more liberal regime, with an increased privatization of public welfare and a focus on individual responsibility regarding the citizens own living conditions. Husby as an area is characterized by a low socioeconomic status, a high level of unemployment and poor school results.

This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result. The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.

 This report deals with thecollaborative project between FagrellProdukt Utveckling AB and studentsfrom the Faculty of Science andTechnology at Uppsala University. Theoverall objective of the project wasin addition to developing students'abilities, to help Fagrell withverification and development ofFagrells prototype, Fundamental flowreactor, for flow chemistry. Theuniqueness of Fagrells flow reactor isthat it should be simple andaffordable compared to competing flowreactors in the market.The verification was done bylaboratory and simulation sessions.The verification shows that Fagrellsidea on how to construct a flowreactor is very good.The development included bothtechnology and business. The result ofdevelopments can be helpful for thecommercialization of Fagrell flowreactor..

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.

AbstractEssay in Political Science, autumn 2010. ?ALBA ? A regional integration project with good conditions?? Autor: Anna Sjögren. Course: Political Science, C-level, Tutor: Sten Berglund An essential part of the political science research on regional integration has been about why states join economic unions and what forces drive the process of integration. This essay is a case study on the Latin American regional integration project called ALBA.

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Dagens låga lagervolymer vid industrierna har inneburit högre krav på transportstyrningen av ankommande virke för att säkerhetsställa en kontinuerlig råvaruförsörjning. Kombinatet i Iggesund, som är en del av Holmen AB, har sett potential att effektivisera sin vedhantering vid det massabruk samt sågverk som utgör kombinatet. Vedhanteringen är idag tydligt separerad mellan massabruk och såg. Studiens syfte var att kvantifiera effekten av ett samarbete med vedhanteringen mellan massabruk och såg samt en förändring i lossningsresurser med avseende på relativa kötider för virkesfordon som ankommer till kombinatet. Med händelsestyrd simulering skapades en modell över kombinatet.

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.
