With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity.
The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program.
The method resulted in four different themes:
1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections.
2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.
Simulering av vindkraftverk och närliggande elnät vid Risholmen i Göteborg i SimPowerSystems
With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
Gridens svar på överlevnad : -en studie om revisorers beaktning av fortsatt drift
An auditors? job is to review the company's figures and, as an independent part, give an accurate picture of its financial situation. Auditors have to relate to ISA where ISA 570 can be found and which deals with the going concern. The standard addresses a couple of factors that may be indications that a company can have problems with their continued operation. The problem is that ISA does not evaluate the events, which is more significant than others in the assessment, but it is up to the auditor to consider.The purpose of this paper is to describe the factors, which the auditor believes is more important than others in assessing the going concern and explain why it is so.
Affärsmöjligheter med Smarta Elnät : En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet
Distributed, renewable generation-units and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ?Smart Grid?.This future electric system rise expectations among actors in the existing electricmarket. International organizations share visions of opportunities for electricityconsumers and new actors, ready to enter the market. At the same time, electricutility companies may question the need for some of these upcoming changes, as theyare sometimes expected to lead the development.This paper therefore seeks to investigate the business opportunities related to SmartGrids.
Den ultimata träningsmetoden?
Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).
Rörelsens betydelse för inlärningsprocessen.
The purpose of this examination was to se how exercise affects the learning capacity. In this work I have chosen to integrate natural science with sport and the target group was a primary department. The two areas I integrate with sports were: the digestive system and knowledge of deciduous trees. I split the class in two different groups. One group got to have a theoretical lesson and the other one got to have an exercise lesson.
Konkurser i små aktiebolag: En studie ur konkursförvaltares perspektiv med stöd av repertory grid -
De senaste åren visar statistik på att allt fler små företag går i konkurs. Bara under 2013 ökade siffran med fem procent gentemot tidigare år. Därför ämnar denna studie att belysa problematiken till varför konkurser uppstår samt vilka bakomliggande signaler företagen tar emot om en annalkande konkurs. Det är inte ovanligt att företag av olika anledningar bortser från signalerna de får om företagets ställning. Studiens huvudsyfte är att öka förståelsen för signaler vid företagskonkurser.För att besvara syftet har studien en kvalitativ metod med kvantitativa inslag.
BLOD, SKATT OCH JORDEB?CKER. En j?mf?rande fallstudie om informationskapacitet i det postkoloniala Latinamerika
Tax revenue is crucial in order for states to survive. States vary a lot in terms of tax revenue
however, and different explanations are frequently debated among political scientists. Recently,
scholars have argued that the variations in tax revenue among European states today can largely be
explained by their ability to collect information about the citizens and their belongings during the
early modern period (1450-1800). States that were early in acquiring this information in so called
cadasters, could use it in order to collect tax. This fiscal capacity thereafter sustained in a path
dependent manner.
Framtagande av OEE-mall
At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).
Utveckling av Innovativa Småskaliga Elförsörjningskoncept : - Minor Field Study i Namibia
A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.
vindkraftens påverkan på elkvaliten
This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.
User Experience utvärderingar med stöd av Repertory Grid Technique
Studiens syfte var att undersöka möjligheterna att använda intervjutekniken Repertory Grid Technique (RGT) som utvärderingsteknik för att utvärdera User Experience (UX) på distans. Detta gjordes genom att de föreställningar som en handledarstödd utvärdering resulterade i jämfördes med det resultat som uppnåddes genom en webbaserad variant av samma utvärdering. Studiens resultat visade på en svårighet för respondenterna i den webbaserade utvärderingen att formulera föreställningar som går att använda för analys av en produkts UX. Diskussionen pekar på en tänkbar lösning i form av förstudier som utförs med en mindre grupp av respondenter för att på detta sätt hjälpa utvärderarna att skapa sig en referensram att använda vid tolkningen av de föreställningar som sedan kan samlas in under en webbaserad utvärdering. Studien syftade även till att jämföra vilka aspekter kopplade till UX som utvärderingarna genererade, samtliga av dessa kopplades till subjektiva eller produktrelaterade aspekter..
Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB
The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.
BIM i förvaltningsskedet - Nyttan för fastighetsägare
The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.
