Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.

Syftet med uppsatsen var att skapa en bild av den bebyggelseförändring som skett i Utviksområdet under de senaste 150-200 åren. Jag har arbetat med flera frågeställningar kring området. Hur långt tillbaka har det varit aktivitet på Mjusen? Hur har området utvecklats från fäboddrift till sågverksindustri till sommarstugeområden och vad finns kvar idag av byggnader och mark? Vilken funktion fyller området idag?För att hitta svar på mina frågor har jag studerat gamla kartor och bilder, läst lokalhistorisk litteratur om ämnet och gjort intervjuer med personer som minns fäboddriftenstid. Jag har även via webben studerat Urban Sikeborgs sida Familjer i Norrala, på Genealogi.se där jag funnit tingsärenden, så långt tillbaka som till 1640-talet, på personer som brukar skogen och marken på fäbodområdet.Genom mitt arbete har jag fått en tydlig bild av hur området förändrats under tid.

Det här arbetets slutgiltiga uppgift har varit att skapa ett första utkast till enövergripande plan för en jämn fördelning av spelmoment för spelet Testament, ett spel som utvecklas för Svenska Kyrkan med syfte att användas inom konfirmandundervisning. Med spelmoment menas exempelvis story, miljö, utrustning och liknande.Arbetet ger inledningsvis en kort översikt över hur leveldesignen inom dataspel har utvecklats och går därefter in på det mer specifika området gameplay progression, utvecklat av Mike Lopez, som ger en översyn över vad som krävs för att skapa ett spel med en jämn fördelning av spelmoment.Därefter används denna metod för att analysera det redan befintliga spelet The Legend of Zelda: Twilight Princess, för att testa Lopez metod, innan arbetet med att skapa en egen plan tar vid.Resultatet av uppsatsen har nått målet med en övergripande plan för en jämnfördelning av spelmoment för spelet Testament, en plan som dock kommer att behöva ses över och omarbetas under det att utvecklingen av det faktiska spelet tar vid, men som ger en bra överblick över vilka delar som fungerar väl och vilka som kan behöva extra arbete i den stundande utvecklingen..

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Bakgrund: Ospecifik ländryggssmärta är en av de vanligaste orsakerna till att man söker hjälp inom primärvården. För långvarig, ospecifik ländryggssmärta är träning ett förstahandsval och fokus har under det senaste årtiondet legat på bålstabiliserande träning. Psykosociala faktorer som self-efficacy och rörelserädsla kan vara viktiga att beakta vid behandlingen då de spelar en roll i hur ländryggssmärtan utvecklas. Syfte: Att undersöka hur skattad smärta, self-efficacy och rörelserädsla samt funktionsnivå förändrades hos enskilda patienter med långvarig, ospecifik ländryggssmärta under och efter en intervention i grupp med bålstabiliserande träning. Metod: Designen var en A-B-A single-subject design (SSED).

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

This thesis has had its focus on ceramic shards found in a trench by the late neolithic western shore of the Ajvide site. The purpose of the thesis is to investigate if there are changes in the pottery between the test trench and the ceramics found by the graves, known as the main site. The author has compared the ornaments from the test trench with an ornament schedule made from over 50 000 shards from the assumed main site. Not only changes regarding ornaments has been noticed but also new techniques and raw material. The author has also implemented two 14C datings which backs his hypothesis that the shards from the test trench are younger than the shards that made the earlier ornament schedule.

The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

Bakgrund: En stram muskel kan orsaka ett försämrat rörelsemönster som i sin tur kan vara orsaken till skada, detta kan dock motverkas genom stretching (töjning). Syfte: Syftet med studien var att undersöka hur och om rörelseökning i hamstringsmuskulaturen skedde genom töjning med KAT-metoden respektive statisk töjning under en töjningsperiod på tre veckor. Metod: Förloppet kring stretching av hamstringsmuskulaturen undersöktes genom töjning varannan dag under 10 interventionstillfällen. Studien genomfördes som en Single-Subject Experimental Design (SSED). Baseline och withdrawalmätningar grundlades där inga töjningar utfördes.
