Abstract:

Functional Magnetic Resonance Imaging (fMRI) is one of the best techniques for neuroimaging and has revolutionized the way to understand the brain functions. It measures the changes in the blood oxygen level-dependent (BOLD) signal which is related to the neuronal activity. Complexity of the data, presence of diﬀerent types of noises and the massive amount of data makes the fMRI data analysis a challenging one. It demands eﬃcient signal processing and statistical analysis methods. The inference of the analysis is used by the physicians, neurologists and researchers for better understanding of

Abstract:

Computational models have long been used to predict the performance of some baseline design given its design parameters. Given inconsistencies in manufacturing, the manufactured product always deviates from the baseline design. There is currently much interest in both evaluating the effects of variability in design parameters on a design’s performance (uncertainty estimation), and robust optimization of the baseline design such that near optimal performance is obtained despite variability in design parameters. Traditionally, uncertainty analysis is performed by expensive Monte-Carlo methods. T

Abstract:

A powerful technique is presented for joint blind channel estimation and carrier offset method for code- division multiple access (CDMA) communication systems. The new technique combines singular value decomposition (SVD) analysis with carrier offset parameter. Current blind methods sustain a high computational complexity as they require the computation of a large SVD twice, and they are sensitive to accurate knowledge of the noise subspace rank. The proposed method overcomes both problems by computing the SVD only once. Extensive simulations using MatLab demonstrate the robustness of the prop

Abstract:

In USA, the Municipal Solid Waste (MSW) landfills accumulate about 130 million tons of solid waste every year. A significant amount of biodegradable solid waste is converted to landfill gas due to anaerobic stabilization by bacteria. These biochemical reactions produce volatile organic compounds (VOCs) like methane and others. Due to heterogeneity in refuse composition, unpredictable distribution of favorable environmental conditions for bacterial actions and highly uncertain pathway of gases, estimation of landfill gas emission for a particular landfill is complex.

Abstract:

An accurate estimation of the charging time of an automotive traction battery is possible only with the knowledge of different parameters of the battery and the vehicle. If this information is not available to the driver, the full time needed for charging of the battery may have to be assessed only from experience. A long route planning and estimation of required service life of the vehicle are therefore only roughly possible. Furthermore, with a better knowledge of estimated charging time, better management of public charging stations and better utilization of charging equipment can be achiev

Abstract:

O veado-mão-curta (Mazama nana) é uma espécie de cervídeo que ocupa a região Sul do Brasil, norte da Argentina e leste do Paraguai, tendo sido severamente afetada pela redução drástica das áreas florestadas. Trata-se, também, da espécie de cervídeo neotropical menos estudada pela ciência. Frente a essa situação, o presente projeto propôs-se a entender como essa espécie se distribui em sua área de ocorrência, propôs áreas prioritárias para sua conservação e estimou a densidade de duas populações. Dada a raridade e a alta elusividade da espécie, propôs-se o uso de metodologias indiretas para se

O mapeamento da estrutura florestal em escala de paisagem nos permite avaliar como as florestas respondem aos impactos da ação humana e a mudanças nas condições ambientais. Neste contexto, a tese tem como objetivo elaborar modelos de estimativa de biomassa acima do solo e fechamento de dossel utilizando imagens de satélite, em diferentes estágios de sucessão de Mata Atlântica localizada em área com complexidade topográfica. Para alcançar este objetivo geral, temos dois objetivos específicos: (1) avaliar o efeito da geomorfologia na modelagem da biomassa florestal e fechamento do dossel; (2) an

Abstract:

碩士<br>逢甲大學<br>通訊工程學系<br>101<br>We design a graphical user interface (GUI) based on MATLAB programming for frequency estimation techniques. For different source signals, the GUI can be easily used to estimate the corresponding frequencies based on different frequency estimation algorithms. Hence the designed GUI can be served as a computer-aided tool for frequency estimation. We first introduce the frequency estimation algorithms used in this GUI. Then we introduce the development of the GUI and its structure and properties. Particularly, we take electroencephalography (EEG) signals as an exam

Abstract:

碩士<br>國立中央大學<br>統計研究所<br>100<br>In clinical research studies, the longitudinal data which pays much attention in recent decade collects the observed event time of interest, called failure time or survival time, along with longitudinal covariates. These outcomes are often separately analyzed and lead us to make biased inferences. Thus, a joint modeling approach is necessarily used to analysis these two parts simultaneously. The estimators obtained from joint model have nice properties, such as consistency, efficiency, and asymptotic normality. The joint Cox model is a popular approach for analy

Abstract:

This thesis aims to solve the mathematical inverse problem of characterizing sea waves based on the responses obtained from a marine vessel sailing under certain sea conditions. By researching this problem the thesis contributes to the marine industry by improving products that are using ocean behavior for controlling ship's dynamics. Knowledge about the current state of the sea, such as the wave frequency and height, is important for navigation, control, and for the safety of a vessel. This information can be retrieved from specialized weather reports. However, such information is not at all

Abstract:

The thesis is about ways to improve the technique of maternal mortality estimation known as the "sisterhood method', which entails questioning respondents on the circumstances of death for any sister who may have died. From the records of maternal deaths that occurred during 1976-90 in the Matlab Demographic Surveillance System (DSS) area, a field station of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), a list was prepared of deceased women's surviving brothers and sisters, aged 15 years and over, born to the same mother.
