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
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
Since the European Union’s inception, creating a well functioning, competitive and integrated market has been at the heart of the Unions project. The four freedoms, free movement of persons, goods, services and capital, which led to the opening of the boarders, have been one of the main forces behind growth in Europe. Today, Europe has become the world’s biggest economy and the Single Market is it
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
This paper is devoted to an extension of Burchnall-Chaundy theory on the interplay between algebraic geometry and commuting differential operators to the case of q-difference operators.
We consider the problem of decomposing polygons (with holes) into various types of simpler polygons. We focus on the problem of partitioning a rectilinear polygon, with holes, into rectangles, and show an Omega (n log n) lower bound on the time-complexity. The result holds for any decomposition, optimal or approximative. The bound matches the complexity of a number of algorithms in the literature,
Multilevel flow modeling (MFM) is a modeling method for complex technical systems in which the goals and functions of the system are explicitly described. MFM can be used as a basis for root cause analysis, where primary root causes are separated from consequential faults, in complex fault situations. Model representations for use in diagnostic reasoning usually describe causality, between paramet
Lower urinary tract (LUT) smooth muscle can be relaxed by drugs that increase intracellular concentrations of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). Both of these substances are degraded by phosphodiesterases (PDEs), which play a central role in the regulation of smooth muscle tone. The distribution and functional significance of PDE enzymes vary in differ
