Myoclonus is a hyperkinetic movement disorder characterized by brief, involuntary muscular jerks. Recognition of myoclonus and determination of the underlying aetiology remains challenging given that both acquired and genetically determined disorders have varied manifestations. The diagnostic work-up in myoclonus is often time-consuming and costly, and a definitive diagnosis is reached in only a m
The traditional parametric approach to Granger causality (GC), based on linear vector autoregressive modeling, suffers from difficulties related to the inaccurate modeling of the generative process. These limits can be solved by using nonparametric spectral estimates in the frequency-domain formulation of GC, also known as spectral GC. In a simulation study, we compare the mean square error of th
Children with advanced neuroblastoma are at high risk for relapse of multidrug resistant disease, despite initial response to intensive multimodality treatment. Neuroblastomas have similarities with immature neuroblasts seen during embryonic development of the sympathetic nervous system (the origin of these tumors). Chemotherapeutic drugs have various mechanisms of action and successfully treated
A Bidirectional Efficient Algorithm for Searching code Trees (BEAST) is proposed for efficient soft-output decoding of block codes and concatenated block codes. BEAST operates on trees corresponding to the minimal trellis of a block code and finds a list of the most probable codewords. The complexity of the BEAST search is significantly lower than the complexity of trellis-based algorithms, such a
This thesis addresses three different topics in wind power plant operation. Most of the research is focused on controlling a wind farm that is required to meet a power set-point. In this mode of operation, the wind turbines are able to vary their power production as long as the total power demand is met. The research investigates how this freedom can be used in order to reduce the fatigue loads e
WHO has expressed that people with intellectual disabilities (ID) often are disadvantaged when it comes to accessing healthcare. However, a more solid evidence base is needed to determine if, and in which parts of the health system people with ID have lower access.
Faults and errors are common in the execution of digital controllers on top of embedded hardware. Researchers from the embedded system domain devised models to understand and bound the occurrence of these faults. Using these models, control researchers have demonstrated robustness properties of control systems, and of their corresponding digital implementations. In this paper, we build a framework
Down to the roots is a project about just that; seeing where things come from and how are they made. I have a background in textile design which I wanted to enhance in this project. Therefore I wanted to examine the technique of tufting. This is a textile technique that is not talked about that much, but most of today’s carpets are made this way. In tufting threads are shot into a fabric, situate
In this essay the problem of finding fair equilibria in auctions with multiple heterogeneous and indivisible items is investigated. We assume an equal number of bidders demanding items as number of items, and that every bidder is assigned exactly one item. Among the theoretical results we show the existence of an equilibrium, strategy-proofness for a particular set of prices and convergence of the
SiC Bipolar Junction Transistor has many benefits such as low on-state voltage drop, high switching speed and high maximum operating temperature. However it has one major disadvantage that it needs current to be turned on. This causes an increased power requirement of the driver circuit compared to voltage controlled devices like MOSFETs and IGBTs. The proposed driving concept is based on a verifi
Statkraft is Europe’s largest renewable energy company, operating in 23 countries, and employs more than 3000 staff. The company generates and develops renewable energy in a broad range, hydropower, gas power, wind power, district heating and is one of the major players on the European power exchange Nord Pool. This thesis will primarily focus on assessing Statkraft’s potential and strategic compe
Some observers claim that ecumenism has entered the season of winter and that ecumenism does not flourish as it has done in other periods. This article proposes that queer theory, an academic field that in different ways addresses and challenges questions of identity, offers perspectives to respond to this challenge and allow ecumenism to enter springtime. One of the main elements within queer the
