While industrial robots have traditionally been designed for tasks such as pick-and-place that require a high repeatability, an increasing demand for off-line control and high-precision applications have in recent decades put higher demands on the accuracy of robots. One application in that vain is the detection of X-rays that have been scattered from a sample during X-ray diffraction, which produ
A good head of beer gives nice texture and prevents releasing of aroma. The beer foam stability depends on numerous parameters. In this study, it was focused on the interfacial rheological properties such as surface tension and dilational modulus in relation the film formation by isohumulones and beer proteins at the air-water interfaces. The isohumulones and beer protein samples were prepared ind
Contactless palmprint recognition is a biometric technology which due to its ease of acquisition, non invasive nature and potentially cheap cost can come to stand competitive to more widely used biometric traits such as finger- or facial recognition. This work uses two different feature extraction methods for palmprint images, the Scale invariant feature transform (SIFT) with an iterative random s
An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. The process parameters were then optimized resulting in a quasi-ALE process suitable for pattern transfer as shown by t
Mänskliga attityder är fundamentala för att bevara jordens ekosystem. Denna studie undersökte sambandet mellan mänsklig empati och upplevelsen av samhörighet med naturen, mer specifikt, med specifika växter. Undersökningen baserades på enkäter och den statistiska analysen gjordes med rmANOVA. Deltagarna (N = 106, medelålder =32,7 SD =16,0) bedömde sin empati och upplevelse av samhörighet med naturHuman attitudes toward nature are fundamental for preserving earth’s ecosystems. This study investigated the malleability of human empathy and connectedness to specific plants. We randomly assigned participants (N = 106, Mean age = 32.7, SD = 16.0) to one of three different induction conditions, and measured trait general empathy and connectedness to nature, as well as state empathy and connectedn
Bosnia and Herzegovina has been one of the countries in the Western Balkans mostly affected by terrorism and the phenomenon of foreign terrorist fighters, which it has had a hard time combating. The country has been on the agenda of EU integration for many years, a process which has taken a very long time, but has in recent years accelerated rather drastically. There are many theories about terror
This thesis is evaluating the pedestrian modelling software Viswalk for the use as a building evacuation model, by verifying and validating the model. In the verification, a procedure from the National Institute of Standards and Technology (NIST) is used as a basis to assess Viswalk’s ability to represent pre-evacuation time, movement and navigation, exit usage, route availability and flow constra
In many application areas in industrial production, industrial robots are utilised for performing various tasks. Frequently a predefined geometric path exists, such that the robot should track this path with its tool centre point. The tracking is often to be performed with certain criteria specified, such as minimisation of time or energy. Accordingly, path tracking problems can often conveniently
The purpose of this Master's Thesis was to compare and coordinate active chassis systems in a search for new ways of controlling two driving situations; side wind exposure and split friction braking. These situations were to be mastered by three active systems; active steering, brakes and suspension. Examples of how to use the systems were presented for each driving situation. The results from
A wheel loader is a tractor-like universal working machine with a bucket in the front which can be used for digging, loading and transporting different type of material. A driver of such a vehicle needs a lot of training and experience before he can handle the vehicle in a safe and efficient way. In order to reduce these demands on the driver, the vehicle should be made more autonomous. As a first
After the formation of the European Union internal market in 1992, member state specific obstacles and barriers were largely removed. This was especially the case in harmonised industries where standardisation and technical regulation have led to legal certainty. Despite this, a large range of trade regulation continues to remain distortional to trade, in addition to the ongoing tariffs and subsid
Finding work for people with severe physical disabilities is not easy. This master thesis aims to investigate the possibility of creating new job opportunities for these people, using speech recognition. One possibility is to construct an application where a person works in a callcentre by using his/her voice. To test the idea a co-operation with the callcentre at Trygg Hansa in Malmö was initiate
To allow the user interface in a mobile phone more space, slide modules are implemented. The usage of slide modules introduces many new challenges when designing a mobile phone. New solutions to these challenges is the main scope for this thesis. Nokia currently has several different slide phones out on the market implementing some sort of slide module. The slide module provides extra space for th
The purpose of this Master’s Thesis was to examine different usage applications for animations and to develop one or several animated products for Sony Ericsson Mobile Communications AB. The overall objective was to develop an animated tool for information purposes and to investigate different interesting fields of application for the animated products. The goal was also to show the procedure of c
Patents on traditional knowledge and the issue of biopiracy has been a debated issue since the Uruguay Round in the early 1990s. In order to handle this problem, the United Nations established the Convention on Biological Diversity and a subsidiary working group on Access and Benefit Sharing. This is supposed to help traditional knowledge holders claim their rights to benefit sharing when commerci
A great number of studies have explored the motivations that drive software developers to devote their time and efforts to contribute to Open Source Software Development (OSSD) projects. Previous studies have stated that both intrinsic and extrinsic motivations are important, however there have been different opinions regarding their relative value. This study further researches OSSD motivations a
The purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. Perturbations from the RF input pulse to
This master’s thesis is part of the project SolarFood, aimed at reducing post-harvest losses through improved solar drying techniques. The project focuses on developing locally adapted solar dryers, with short drying times while considering socio-economic factors for technology adoption and diffusion. This paper investigates adoption barriers and potential drivers for the diffusion of solar dryer
