The generalized hole corrected Debye-Huckel theory (Penfold et al J. Stat. Mech. (2005) P06009) is implemented. Predictions of thermodynamic functions and simple structural properties compare favourably with results from closure of the Ornstein-Zernike integral equation in the mean spherical approximation, and with Monte Carlo simulation of the charged hard sphere primitive model. A strictly nonel
We present a quenching result for semilinear parabolic equations with dynamic boundary conditions in bounded domains with a smooth boundary.
Objective Incidence of cardiovascular disease (CVD) is higher in men than in women. The aim of this study was to investigate whether the gender differential can be modified by pharmacological intervention in a population-based setting. Design and method In a prospective population-based cohort - the Malmo Diet and Cancer study - a total of 3608 hypertensives (1559 men, 2049 women), 45-73 years old
Recent marsupials include about 280 species divided into 18 families and seven orders. Approximately 200 species live in Australia/New Guinea. The remaining species inhabit South America with some of these secondarily ranging into North America. In this study, we examine marsupial relationships and estimate their divergences times using complete mitochondrial (mt) genomes. The sampling, which incl
A fast spectral approximation of a narrow-band computer model is proposed for prediction of thermal radiation in a generally nonisothermal and nonhomogeneous combustion environment. The approximation is made by assuming each discretized spatial element along a line of sight to be locally "gray" within each small narrow-band spectrum interval. For each spatial element, the local equivalent spectral
An experimental study was performed to investigate the dependency of particle size on the deposition rate. Polystyrene latex particles of two radii (0.23 and 0.38 mum) were deposited onto a glass surface covered with indium-tin oxide. Reduced deposition efficiency was observed for the larger particles, although an increase in the deposition efficiency was seen as that the diffusion boundary layer
This thesis explores the application of machine learning techniques to predict mortality risk using data from the Swedish Adoption/Twin Study of Aging (SATSA). Through the development and evaluation of multiple supervised learning models, including Random Forest and Histogram Gradient Boosting classifiers, the study examines mortality predictors across 10-year and 20-year timeframes. The models ac
This chapter addresses the background of the study, statement of the problem, objectives or aims of the study research questions, significance of the study and scope of the study. The Uganda Maritime Regulatory Framework is a Service that helps to overcome borders and barriers that affect interaction and form a greater part of probably the most characteristic dimension of cross - border networks t
Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterised by motor and non-motor symptoms, including significant speech impairments. Early and accurate diagnosis is crucial for effective management and treatment. However, traditional diagnostic methods are often limited because they rely on subjective assessments and only detect symptoms after they have become noticeable.
SAAB Dynamics produces and develops warheads and uses computer simulations to evaluate its products. Recently, SAAB has begun using neural networks to quickly obtain accurate outputs, based on simulated data, from a set of input variables with success. This thesis investigated whether interim data in the form of video frames can improve the output of the network. This thesis investigated the use o
A new pharmaceutical product suitable to act as a negative contrast agent for Computerized Scan (CT-scan) of the abdomen is under development. At the moment the product has the form of a powder, which when dispersed in water and whipped, gives a stable foam. The foam is ingested by individuals who are about to undergo a CT-scan, as a prior preparation step. The powder form has disadvantages such a
The aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. Because of the high numerical complexity of GPs, sparse approxi
It is important to the recruitment company that only quality candidates, and the candidates most likely to receive an offer of employment get short-listed to go through the carriers selection process. It is this second phase of the recruitment process, the short-listing of potential candidates, that will be the focus of this thesis. Data has being gathered by the recruitment company through an i
Syftet med examensarbetet är att undersöka möjligheten att presentera en kompositvy där den ena delen av vyn visar bilens omgiving, sett ur ett fågelperspektiv, och den andra visar bilens backkamera. För att undersöka denna möjlighet byggdes två prototyper baserade på två separata implementationer av parkeringskameran. Den första prototypen baseras på Volvo Car Corporations egen version av AndroidIn this thesis two prototypes, based on separate implementations of a Park Assist Camera, was developed. The purpose was to investigate the possibility of presenting a composite view, where the first view shows the surroundings of the car from a bird’s-eye view and the other view shows the rear camera. The first prototype was based on Volvo Car Corporations flavour of Android OS, where the perform
To be able to meet the global energy demands, a steady supply of green energy is required, even during sun- or windless hours. Concentrated solar power is a useful alternative, which can produce and store green energy by heating a heat transfer fluid (HTF) and extracting its energy via a heat exchanger. One such category of HTF is molten salts, and to understand and be able to model the behaviour
An integrated lunar habitat system is proposed, combining mycelium-based biological materials, autonomous robotic construction, and modular architectural strategies to enable long-term adaptation in extreme environments. Before human arrival, robotic units construct the primary structure and initiate mycelium growth along interior surfaces. This fungal layer functions as a living sensor network, w
The QR decomposition is used to solve least squares problems, systems of equations and other important linear algebra tasks. We consider the computation of the QR decomposition for tall-skinny matrices, using the Cholesky decomposition as an intermediate step. To improve efficiency, we introduce randomised numerical linear algebra and sketching as a tool for improving computational efficiency. Num
