This article contains a study of how spatial errors and receiver imperfections affect the angle of arrival estimation accuracy for virtual antenna arrays. A virtual antenna array consists of one receiver element whose location is tracked as the element is moved and in this work, linear arrays are studied. If the location of the receiver is tracked using an inertial measurement unit, an interesting
We aimed at assessing changes in AV nodal properties during administration of the beta blockers metoprolol and carvedilol, and the calcium channel blockers diltiazem and verapamil from electrocardiographic data.
The Åland Islands were recently ranked as Finland's healthiest region with lower prevalence of several non-communicable diseases compared with the national mean. We have compared birth characteristics of 1697 individuals born on the Åland Islands between 1937 and 1944 with contemporaneous data from the Helsinki Birth Cohort Study (HBCS; n=11,808). This is a first step towards a potential future an
We consider the problem of approximating a given function in two dimensions by a sum of exponential functions, with complex-valued exponents and coefficients. In contrast to Fourier representations where the exponentials are fixed, we consider the nonlinear problem of choosing both the exponents and coefficients. In this way we obtain accurate approximations with only few terms. Our approach is bu
In this paper, we describe a concise method for the feature-based representation of regions in an indoor environment and show how it can also be applied for door-passage-independent detection of transitions between regions to improve communication with a human user.
Studies on the associations between cognitive abilities and life satisfaction (LS) in the oldest-old are few. The aim of this study was to explore whether abilities in six different cognitive domains could predict LS in the oldest-old 3 years later.
The last decade many African emigrants have tried to enter the European Union and Spain and the Spanish government and the EU have developed different measures to stop this immigration. The aim of this thesis is to discuss and analyze the immigration management measures taken by Spain and the EU to see how well these function, and if they have any consequences for the immigrants. Different theorie
The aim of this paper is to make an investigation of how authoritative conceptual framework about immigrants as a group is being constituted in the discourse regarding Swedish language for immigrants. I will also examine what connections there are to the overarching integration discourse. While doing this I try to establish the contrasting relationship between the ?Swedishness? and ?the Other?. My
The thesis is inspired by the events that surrounded the Office of the Director of Public Prosecutions and it seeks to elaborate the fact that political interference has repercussions on human rights as stated by both national and international law. It looks at fighting corruption under the theme of good governance at another angle.
This study is an attempt to analyse whether the Human Rights based approach is a viable tool towards implementing the right to development consequently attaining the right to food in Malawi. The question to be determined is whether the unfreedom from hunger of vulnerable and marginalized groups can be overcome by implementing development programs relating to the right to food as a component of the
The condemnation of the specialized procedures of the faulty military commission system, particularly ex parte and in camera hearings to determine the closure of confidential information, has resulted in the contention that terror cases may be properly adjudicated in regularly constituted Article III courts. Proponents of prosecution of terror suspects in federal civilian courts assert that the co
Popular science summary: How do bacteria divide? Cell division is an absolute requirement for proliferation of all bacteria and results in the bacterium being split into two by a septum. FtsZ is a protein that plays a key role in bacterial cell division. In this project, one part of the FtsZ protein was investigated with genetic methods to understand how it affects the division process. Previou
Today’s cloud data center infrastructures are not even near being able to cope with the enormous and rapidly varying capacity demands that will be reality in a near future. So far, very little is understood about how to transform today’s data centers (being large, power-hungry facilities, and operated through heroic efforts by numerous administrators) into a self-managed, dynamic, and dependable i
This dissertation investigates the relationship between cultural diversity in top management team (TMT) and organisational outcomes. The theoretical framework developed within this dissertation identifies three major concerns in this relationship. Firstly, the issues related to the lack of research on the contingencies, secondly problems associated with the method of inquiry, and thirdly the conce
In this paper an approach for improving robot machining accuracy through simulation-assisted path planning within Computer-Aided Manufacturing (CAM) tools is investigated. The method comprises modeling of dynamic robot behaviour under influence of process forces and a subsequent simulation of the robot motion which results in an offline prediction of deflection errors during the machining task. Th
Fetal immobilization affects skeletal development and can lead to severe malformations. Still, how mechanical load affects embryonic bone formation is not fully elucidated. This study combines mechanobiology, image analysis and developmental biology, to investigate the structural effects of muscular loading on embryonic long bones. We present a novel approach involving a semi-automatic workflow, t
Small autonomous surface vehicles (ASV) will need both teleoperation support and redundant positioning technology to comply with expected future regulations. When at sea, they are limited by a satellite communication link with low throughput. We have designed and implemented a graphical user interface (GUI) for teleoperation using a communication link with low throughput, and one positioning syste
The effect of Ca++, Mg++, K+ and SO=4, and of serum, on the activity of testis hyaluronidase in a carbonic acid-bicarbonate buffer with pH 7.4 was investigated with the turbidimetric method. The ions were added in amounts corresponding to the serum concentration of the ion in question.The turbidity of hyaluronic acid was not modified by the investigated ions nor by serum up to 0.10 ml.The hyaluron
HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a protein-lipid complex from human milk with both tumoricidal and bactericidal activities. HAMLET exerts a rather specific bactericidal activity against some respiratory pathogens, with highest activity against Streptococcus pneumoniae, but lacks activity against most other bacterial pathogens, including Staphylococci. Still, ion trans
