We have experimented with different SOM-based architectures for bio-inspired self-organizing texture and hardness perception systems. To this end we have developed a microphone based texture sensor and a hardness sensor that measures the compression of the material at a constant pressure. We have implemented and successfully tested both monomodal systems for texture and hardness perception, bimoda
First predictions for specific case of the particle-hole-core coupling model which takes advantage of symmetries of a triaxial rotor with gamma = 90 degrees are reviewed. Results of the model calculations point towards existence of stable chiral geometry in specific configurations involving high-j orbitals. Next, experimental information on doublet bands built on unique parity, pi(h)11/2(Vh)11/2 i
Fluorescence techniques for applications in tissue diagnostics and therapy monitoring were investigated and developed in the work presented in this thesis. The aim was to develop fluorescence diagnostics for the detection of malignant tumors and better delimitation of the tumor margins, using the enhanced contrast in fluorescence between tumor and surrounding healthy tissue. Fluorescence may be ge
Hidden Markov models (HMMs) are probabilistic functions of finite Markov chains, or, put in other words, state space models with finite state space. In this paper, we examine subspace estimation methods for HMMs whose output lies a finite set as well. In particular, we study the geometric structure arising from the nonminimality of the linear state space representation of HMMs, and consistency of
A high resolution TPC is the main option for a central tracking detector at the future International Linear Collider (ILC). It is planned that the MPGD (Micro Pattern Gas Detector) technology will be used for the readout. A Large Prototype TPC at DESY has been used to test the performance of MPGDs in an electron beam of energies up to 6 GeV. The first step in the technology development was to demo
This article presents a research agenda about waste management from the perspective of management and organization studies. The agenda suggests that scholars should draw upon research on waste governance, lean management, the circular economy, and sustainable consumption. It also suggests, in a crossdisciplinary spirit, that scholars should heed research on waste within other social sciences and t
Popular Abstract in Swedish Under de senaste årtiondena har både kraftsensorer och digitala kameror kommit att bli vanliga som sensorer i olika robotiktillämpningar. Denna avhandling behandlar olika problem inom visuell rörelseskattning och återkoppling, samt integrationen av dessa tekniker med reglering av kontaktkrafter för en industrirobot. Olika ämnen tas upp, från grundläggande teori till praOver the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. Different topics ranging from basic theory to system implementation and applications are treated. A new interface develo
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
Analysing eye movements recorded with mobile eye-tracking devices is difficult since the eye-tracking signals are severely affected by simultaneous head and body movements. The automatic analysis methods developed for static eye-tracking systems do not take this into account and are therefore not suitable for application to data which also contains head and body movements. As a result, data record
Problem discussion: To be competitive in a changeable environment, as the video surveillance market, in a time when the company and the market grow with almost 40% yearly, the sales organization must be well trimmed and effective. Knowledge about customers’ needs and what makes success are essential parts of the progress. Sales Product Management (Sales PM) is a new group at Axis with the main tas

Frigoscandia Freezer AB have seen themselves as an entrepreneur company for a long time, but have lately begun to realise that they have to go against a more administrative era. With that insight they have begun to examine their enterprise in order to achieve this. The division Team Spare Parts has started a project with the intention of checking-up the inventory management, and improving it for t
