This Master Thesis aims to show an approach to the design of parallel robots,specifically the development of its kinematics. To do this, screw theory will be used, focusing on its theoretical bases and taking it later to practice. First, a theoretical definition of the inverse and forward kinematics of a parallel robot is carried out. Subsequently, algorithms are generated in Python that verify t
Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to m
In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled. Examples of variables are heat release, ventilation mode and factors within evacuation modelling
Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. Estimating the fundamental wing beat frequency (FWBF) of insects is important in order do this classification of species, which is an area of research that has been explored previously. In this thesis, the relative phase
This study assesses the impacts of the floods in early 2011 in the Northern Cape Province in South Africa and focuses especially on the small town Keimoes located on the major Orange River. During this period 33 municipalities in 7 out of the country’s 8 provinces were declared as disaster areas due to widespread flooding. In Keimoes and the Northern Cape Province the flood impacts were widespread
This thesis is based on the two months I spent in Bolivia doing applied cultural analysis for a nongovernmental organization (ECAM) that works for women empowerment and gender equality. My intention is to explore the relationship between academia and activism by focusing on the approaches that have been pointed out as counterproductive in the struggle for gender equality. Specifically, the objecti
The thesis explores the possibilities of the Swedish government to assure effective waste collection policies for mercury-containing gas-discharge lamps (GDL) in the context of phase-out of incandescent light bulbs. The study includes review of the waste collection, the waste collection evaluation, policy review and policy analysis. The specific analytical tools applied include Lindhqvist’s policy
Ett första steg i arbetet att uppskatta kolflödet mellan landbaserade ekosystem och atmosfären är att så precist som möjligt analysera kvantiteten ovanjordisk biomassa. LiDAR teknologi har i detta avseende visat sig vara ett värdefullt verktyg. Det överlöpande målet med denna studie är att utveckla en förenklad metod, baserad på fjärranalys, för att uppskatta ovanjordisk biomassa för individuella As a first step in the assessment of carbon flux between the terrestrial environment and the atmosphere it is important to accurately quantify the carbon stock of forest ecosystems. LiDAR technology, in this respect, has proved to be a valuable tool, able to provide accurate estimates of aboveground biomass (AGB). The overall goal of this study was to develop a simplified method for assessing AGB
This thesis is focused on exploring what insights a human ecological perspective could provide on the understanding and practice of political consumerism. This is divided and conducted in two sections, the first section is a theoretical discussion which is devoted to defining political consumerism and reconseptualizing some aspects and components of it as well as to positioning it in a wider and m
Background: Customers for buses and coaches on the European market ask for complete vehicles from one supplier. Since Scania CV are only manufacturing chassis, their sales companies must co-operate with body builders in order to offer a complete product and service backup. This means that the sales companies in connection with every order have to deal with two order processes, one for Scania CV an
Magnetresonans, förkortat MR, är ett fysikaliskt fenomen som tillämpas inom medicinsk diagnostik för bildtagning. Med hjälp av mycket starka magnetfält kan bilder erhållas, exempelvis på hjärnan, utan att joniserande strålning används. Förutom bilder kan MR-bildtagning även användas för att avbilda perfusion (kapillärblodflöde) och vattendiffusion i hjärnan. Ytterligare ett användningsområde är av
This examination work is the final work in our education to become a Bachelor of Science in Mechanical Engineering by the University of Lund. The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all
Titel- Sex and the city för män? ?En kvalitativ studie om manligheter i förändring Författare- Malvina Britts Avdelning- Avdelningen för Medie- och kommunikationsvetenskap Problem: Området som min studie rör sig inom är representationen av maskulinitet. Förändringar i representationen av maskulinitet diskuteras i olika sammanhang och en specifik drama/komediserie, Entourage, har på sistone utmä

The frequent replacement of office furniture contributes to the increasing production of solid waste that leads to the use of more landfill space. Germany only produces approximately 700000 t of office furniture waste per year whereas most of this waste goes to landfill or incin-eration (Nolte, 2001). In addition, there are concerns about the use of hazardous chemicals in office furniture producti
Presentation of problem: The movement of sediment parallel to the coast by waves and currents is known as longshore sediment transport or littoral transport. Throughout the years, researchers have found that knowledge of longshore sediment transport is important in connection with coastal engineering design, such as construction of breakwaters at harbour entrances, dredging of navigation channels,
The present study investigated the effects of three factors on the level of realism in frequency judgements. These factors were: Instruction (No correction for guessing/Correction for guessing), Format (whether the frequency judgements were made in terms of absolute numbers or in percent) and Difficulty level (easy/hard set of questions). All three factors were found to have a significant effect o
Parallel trade in goods is generally viewed as a positive phenomenon within the EU as a consequence of the principle free movement of goods: When traders buy goods in one part of the common market at a low price and transfer it to a higher priced area, allowing them to undercut those prices, then this will enhance competition, drive down prices and give consumers more choice- an overall positive e
