Domain-continuous visibility determination algorithms have proved to be very efficient at reducing noise otherwise prevalent in stochastic sampling. Even though they come with an increased overhead in terms of geometrical tests and visibility information management, their analytical nature provides such a rich integral that the pay-off is often worth it. This paper presents a time-continuous, prim

Nowadays, with the increasing complexity of System-on-Chip (SoC), traditional debugging approaches are not enough in multi-core architecture systems. Hardware tracing becomes necessary for performance analysis in these systems. The problem is that the size of collected trace data through hardware-based tracing techniques is usually extremely large due to the increasing complexity of System-on-Chip

Bitumen är den tyngsta produkten från raffinaderier. Den är användbar som bindemedel för olika ytbeläggningar som t.ex. asfalt på vägar, takpapp m.m. Företag Nordic Waterproofing tillverkar takpapp i Höganäs och använder bitumen som en av de viktigaste råvarorna i processen. Ett förnyelsebart samhälle är dagens fokusmål för alla, inte bara enskilda personer, utan hela landet och hela planet måste Nordic Waterproofing is one of the largest roofing felt producers in Europe. One of the production facility is located in Höganäs (Sweden), which is specialized in roofing felt that are suitable for the nordic climate. Bitumen is a central component of roofing felt manufacturing that contribute several properties to the product. Due to the importance of bitumen, Nordic Waterproofing finds an addit

Microsoft Word - Summary översatt.doc 1 Summary This thesis begins with a quote from Bertolt Brecht. In an aphorism about Mister Keuner, “What is wise about the wise man is his stance”, Brecht discusses knowledge – not any knowledge, but embodied knowledge, a knowledge which produces a stance, in the Brechtian sense of the word. The quote does a good job of summarizing the discussion about the ac

Branchless banking, the use of alternative delivery channels such as mobile banking and agent banking, is becoming increasingly popular among commercial banks in Kenya and in other developing countries. It is believed to reach the low-income and rural individuals as well as making these individuals better off. This study is an attempt to examine whether the use of mobile banking and agent banking

Hålla tarmbakterier i schack hos unga möss Efter födseln exponeras ett spädbarn för den yttre miljön för första gången. Detta innebär exponering för ett stort antal bakterier och virus. Spädbarn är mer benägna att bli infekterade av bakterier och virus än vuxna. Hos vuxna kan antikroppen Immunoglobulin A (IgA) hjälpa till att hålla bakterier och virus i schack genom att omsluta dem och agera som The period after birth, when an infant is initially exposed to vast amounts of environmental and microbial antigens, sets the stage for proper immune system development ensuing lifelong immunity. Simultaneous to this first-time exposure, the nursing mother provides immune protection via antibodies in the breast milk. Secretory Immunoglobulin A, as provided by the mother or produced intrinsically i

Breast tomosynthesis (BT) is a new X-ray modality that reconstructs the breast volume in many slices instead of, as in mammography, showing a single 2D projection of the breast. The slice thickness is typically 1 mm for clinically used BT-units. In screening the review of breast images with BT takes two to four times longer than the review of mammography images. In an effort to reduce the review t

Title An authentic product – A study of authenticity within food Seminar date 2012-05-29 Course Master thesis in Consumer Culture Theory, 30 University Credit Points (30 ECTS).

Introduction: The main route of excretion of activity for most administered radiopharmaceuticals is via the urinary bladder and it is important to estimate the absorbed dose to the mucosal surface of the bladder wall, especially when radiopharmaceuticals are given for therapeutic purposes. The purpose of this thesis was to investigate how the absorbed dose varies with changes in the parameters, wh

This essay explores the ethical dilemma surrounding the construction of green mines on indigenous lands and seeks to determine whether such actions can be justified. The aim is to show that a prioritisation between two seemingly good things is not always a given. Using a normative study framework, the research investigates a conflict of value between different interpretations of the value of the G

How do small states approach their security problems? What types of strategic instruments exist for small states, and when and why are certain strategies chosen rather than others? The security of `weak' states is problematic, demanding trade-offs in the decisions made. Using 19th century Swedish security policy as an example, it is argued here that small states, in their pursuit of security and a

Characterizing population fluctuations and their causes is a major theme in population ecology. The debate is on the relative merits of density-dependent and density-independent effects. One paradigm (revived by the research on global warming and its relation to long-term population data) states that fluctuations in population densities can often be accounted for by external noise. Several empiric

Large increases in regional cerebral blood flow (rCBF) have been measured in patients with Parkinson's disease (PD) following the administration of L-DOPA, but the underlying mechanisms have remained unknown. In this study, we have used rats with unilateral 6-hydroxydopamine (6-OHDA) lesions as a model of PD in order to compare the patterns of rCBF and regional cerebral glucose utilisation (rCGU)

The energy justice framework serves as an important decision-making tool in order to understand how different principles of justice can inform energy systems and policies. The realization of the urgency of providing modern energy technology and services particularly to rural areas has prompted both the Nepalese government and development institutions to focus on community-run renewable energy faci

We present an optimal adaptive controller that is used to regulate the chemical process of wood ash stabilization (WAS). The model parameters of the time-varying process dynamics are estimated using recursive least squares (RLS). At each batch an auto-tuning sequence produced with the controller disabled is carried through in order to obtain a good estimate of the process dynamics. After the auto-

This study begins in the understanding of sustainable development as a complex matter open for interpretation, and continues in the notion that different dimensions of sustainability create different values that have different goals; meaning that they will sometimes unite, and sometimes collide and lead to trade-offs. The aim for this study is to add to the understanding of this matter through an

This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. The first class of algorithms relates to the calibration of the transceiver (TRX) chains responses of the antenna array and makes use of the antenna array mutual coupling, which

Most electricity in Lebanon is produced by burning fossil fuels, which produces more than one half of domestic greenhouse gas emissions, and the state-owned electricity companies are unable to meet the demand. To increase the country’s generation capacity and simultaneously combat the effects of climate change, the government aims to produce 30% of its electricity from renewables by 2030. It is ho
