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
Powders are complex systems that depend strongly on how the individual particles in- teract and their surroundings. Understanding powders behaviour under certain conditions is very important for the product in many applications, one of them being Additive Manu- facturing (AM). The overall goal of this study is to understand and quantify the effect of flow additives in combination with iron powder.
The focus of this work has been to implement a generic netlist reduction engine to speed up circuit simulations. The netlist reduction techniques are further optimized for Static Random-Access Memory (SRAM), wherein we exploit the repetitive pattern of the circuit. There are many driving factors for developing a netlist reduction engine for SRAM simulations. In today's System on Chip (SoC), S
In this project the concept of digital power was examined. Though not a new phenomena, the concept was new to Micropower. The company develops a wide array of battery chargers and wanted to include this concept in future generations of their products. The reasoning behind the decision is the possibilities of smoother development, better error handling and more communication. As a first step differ
The development seen within industrial automation in recent years enables the emergence of manufacturing sites that utilise technology for improved productivity, quality and safety. Increased communication demands introduced by Industry 4.0 have motivated the development of cloud-fog automation; a technique characterised by wireless communication between lower levels of the automation pyramid. Spe
Technical development often precedes scientific breakthrough but can also pose new challenges to the scientific community. This is the case for Digital Spatial Profiling (DSP), where recent breakthroughs allow for collecting multi-plex spatial proteomic/transcriptomic data from tissue and it is prophesied a promising future in cancer research. A challenge, however, is handling its output data with
The goal of risk and vulnerability research is to reduce the harm done by disasters. A disaster is a combination of a natural hazard and a vulnerable society. Understanding vulnerability is vital to reduce disaster risk, or the potential of losses in property or life. Vulnerability is often divided into a technical, relating to buildings, infrastructure, and so forth, and a social which concerns t
The Implementation and some mathematical properties of GMRES and weighted GMRES (WGMRES) are described. Numerical experiments originally performed by Essai (1998) are performed to compare the two methods. GMRES and WGMRES are used to solve a linear system arising from the Poisson equation and compared with respect to computational effort.
Alzheimer’s Disease (AD), a neurodegenerative disease, defined by abnormal accumulation of proteins, both extracellularly (senile plaques, consisting of amyloid-beta(Aβ) accumulation) and intracellularly (neurofibrillary tangles, formed by Tau protein). Several studies demonstrate that the immune cells play a central role in the pathogenesis of AD, but it is not known if immune cells from the peri
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
The European Union (EU) taxonomy regulation marked a milestone in the sustainable finance agenda. The taxonomy aims to accelerate the mobilisation of public and private finance to support the transition to a net-zero economy. The EU’s taxonomy regulation established a classification system of environmentally sustainable economic activities to provide financiers clarity on what to consider a sustai
With the vast processes of digitalization and digitization taking place in many countries in the world, the small northeastern European country Estonia has managed to make incredible advancements in the field of technology and in creating a digital society. Today, the most digitized country and government in the world provides a vast majority of governmental services online, presents the most unic
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
I höst kommer rymdobservatoriet Gaia att sändas upp. Ett av dess mål är att mätapositionen av stjärnor med väldigt hög noggrannhet, denna positionsbestämning kallas astrometri. Gaias noggrannhet är såpass bra att det kommer bli möjligt att även mäta hur planeter när de färdas i sina banor runt stjärnor påverkar positionen av stjärnan. Astrometri kan inte ge en fullständig bild av hur planeten rörContext: The Gaia satellite will be provide astrometry with micro-arcsecond accuracy. This will allow for the determination of the orbital elements of exoplanets with measurable astrometric signature. Astrometry alone is not be able to disentangle an ambiguity in the orientation of planetary orbits, just as radial velocity is only able to give the mass of orbiting planets combined with multiplicat
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
