Kapsprickor och avverkningsaggregat
This study was made for the Swedish forest company Sveaskog because the sawmills they delivered timber to had noticed a high frequency of bucking splits in their products. Coworker Jim Edström at Sveaskog also wanted to know if there was a big difference between different felling heads. The purpose with this study has been to find out the amount of bucking splits and if there is any felling head brand that did a bigger damage that the others.
The study was made in two steps, where the first part was a literary review to find out results and conclusions in earlier studies. The best measuring method to check bucking splits was the known ?trissmetoden?.
Utvärdering av försvarsspecifika radiovågformer
To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.
Produktivitetsstudie Brobyggnad
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Genomförandet av bemanningsdirektivet 2008/104/EG : En problematisk implementering för Sverige?
AbstractThe use of temporary agency workers has increased significantly during the last decades. Due to considerable differences in the legal status and working conditions of temporary agency workers within the EU, the directive 2008/104/EC on temporary agency work was adopted in 2008. The current directive has a two folded purpose, first and foremost to improve the employment and working conditions for temporary agency workers, by establishing the principle of equal treatment. The second purpose is to create greater acceptance for the temporary work agencies, and also to review and remove any unjustified restrictions or prohibitions against them.There are several different models for labour market regulation represented within the EU. The Swedish and Nordic model has through history relied heavily on regulation via collective agreements, entered into by the social partners, with a minimal amount of state interference and regulation.For Sweden there is a potential problem in the implementation of the directive on temporary agency work, since it follows from case law by the European Court of Justice (ECJ).
Auditiv deprivering : i ett audionom perspektiv
Studien riktar sig främst till audionomer, och andra med intresse av hörselrehabilitering.Auditiv deprivering kan visa sig som en med tiden försämrad taluppfattning i örat som inte fått adekvat stimulering. Vad som karaktäriserar dem som drabbas är inte klarlagt. Inte heller vet man exakt orsak eller tidsförlopp. Genom att hörapparatanpassa det drabbade örat har effekten kunnat reduceras och i vissa fall har fullständig återhämtning konstaterats.Litteraturstudiens syfte var att belysa fenomenet och aspekter som bör beaktas i audionomens arbete med insatser av både förebyggande och rehabiliterande karaktär. Metoden var att granska artiklar framtagna genom systematisk och manuell sökning, i databaser tillgängliga genom Örebro universi¬tet.Resultatet visar att personer med hörselnedsättning av såväl sensorineural som konduktiv art drabbas.

Frihet - Vår tids Politiska filosofi? : En idéanalys av den internationella debatten om Chávez socialistiska politik
AbstractEssay in political science, C-level, by Julia Leonsson, spring semester 2007Tutor: Susan MartonFreedom ? The political philosophy of our time?An analysis of the ideas of the international debate aboutChávez socialistic politicSince more than 2000 years there has been an ongoing discussion about whether state interference is a good thing or not. Most international organisations on the international political arena are today founded on neoliberal values, and it has developed in to the hegemonic ideology of the world. The socialistic politics of the Venezuelan president, Hugo Chávez is thereby a somewhat unusual strategy. The purpose of this essay is to examine to what extent the international debate about Chávez socialistic politic can be understood through a neoliberal perspective.
Varumärkesexponering i televisionen : - en jämförelse mellan SVT och TV4 2003 och 2006
AbstractTitle: Brand exposure in television. A comparison between SVT and TV4 2003 and 2006.Number of pages: 57 including appendixAuthor: Axel VictorinPeriod: Spring 2008Course: Media and Communication studies CUniversity: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: The aim of this study is to evaluate the prevalance of brand exposure in Swedish public service television, SVT and TV4. The Swedish public service TV broadcasting company, Sveriges Television (SVT) advertises itself as purveyor of free television, without commercial or political interference. A B-level essay, written some years ago, showed that the SVT policies were not always observed throughout the entire organisation. The aim of this essay is, by using quantitative research, to study whether SVT is letting commercial interests have their say in the programmes by exposing brand names and logotypes.Material/method: The study is performed through examining 40 hours of television from SVT and 40 hours from TV4, as reference.

Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
Att veta Gudarnas hemlighet : En sårbarhetsanalys av omständigheterna kring stormen Gudrun med pressure and release modellen
The concept of vulnerability is the capacity or the sensitivity to become damaged. Vulnerability are characterized by one or more of the following terms; a system´s sensitivity to exposure to shock, stress or interference, the state of the system in relations to a threshold of damages, and the system´s ability to adapt to the changing circumstances. Vulnerability in this study is referring to the sensitivity of the circumstances that lead to sustainable livelihood that can´t be maintain and that there is an inability to cope with and manage stress. The choice of making a study in this area is based on that action needs to be taken to moderate the vulnerable aspects of society, in this respect in relations to storms. Analyzes of the social vulnerability to climate change or natural events is needed for effective actions.
Produktivitet i robotcell
The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.
Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare
Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil.
Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations.
The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses.
The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.
Poultry producers? perceptions of changing market conditions : a field study of the poultry production in Khartoum state of Sudan
Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999).
The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.
Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor
Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.
