Résumé :

Scientific computing and computer simulation play an increasingly important role in scientific investigation and engineering designs, supplementing traditional experiments, such as in automotive crash studies, global climate change, ocean modeling, medical imaging, and nuclear weapons. The numerical simulation is much cheaper than experimentation for these application areas and it can be used as the third way of science discovery beyond the experimental and theoretical analysis. However, the increasing demand of high resolution solutions of the Partial Differential Equations (PDEs) with less c

With the increase use of smart phones the mobile positioning is now extensively used for location based services (LBS’s).

The semi-analytical method, widely used for calculating derivatives of static response with respect to design variables for structures modeled by finite elements, is studied in this research. The research shows that the method can have serious accuracy problems for shape design variables in structures modeled by beam, plate, truss, frame, and solid elements. Local and global indices are developed to test the accuracy of the semi-analytical method. The local indices provide insight into the problem of large errors for the semi-analytical method.

At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists.

With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established gu

Résumé :

This thesis shows highly encouraging results as the gain of accuracy reached 18.4% when the pairwise comparisons method was used instead of the direct method for comparing random shapes. The thesis describes a heuristic for generating random but nice shapes, called placated shapes. Random, but visually nice shapes, are often needed for cognitive experiments and processes. These shapes are produced by applying the Gaussian blur to randomly generated polygons. Afterwards, the threshold is set to transform pixels to black and white from di erent shades of gray.

Résumé :

Soil CO2 efflux (F-soil) represents a significant source of ecosystem CO2 emissions that is rarely quantified with high-temporal-resolution data in carbon flux studies. F-soil estimates can be obtained by the low-cost gradient method (GM), but the utility of the method is hindered by uncertainties in the application of published models for the diffusion coefficient. Therefore, to address and resolve these uncertainties, we compared F-soil measured by 2 soil CO2 efflux chambers and F-soil estimated by 16 gas transport models using the GM across 1year.

The distributed point source method, or DPSM, developed in the last decade has been used for solving various engineering problems-such as elastic and electromagnetic wave propagation, electrostatic, and fluid flow problems. Based on a semi-analytical formulation, the DPSM solution is generally built by superimposing the point source solutions or Green's functions. However, the DPSM solution can be also obtained by superimposing elemental solutions of volume sources having some source density called the equivalent source density (ESD).

Shape and size of rocks are important physical characteristics of aggregates used in engineering and for interpretation of the genesis of naturally occurring sediment. Several image processing programs are available for measure the size and shape of various types of objects. The accuracy and reproducibility of results of a new imaging method and new matlab based 3D imaging program has been studied. 3D results are obtained by coupling two images of particles one of their largest and one of the smallest projected areas.

One application of PET/CT is diagnosis of tumours using ¹⁸F-FDG as a radiotracer. Early detection of small lesions is imperative to improve diagnosis.

Ordered Subset Expectation Maximization (OSEM), the standard image reconstruction algorithm in the clinic, creates mottled images making small lesion detection for ¹⁸F and ⁹⁰Y PET imaging difficult.

There are many problems that lead to analysis of dynamical systems with phase variables of two types, slow and fast ones. Such systems are called slow-fast systems. The dynamics of such systems is usually described by means of different versions of perturbation theory. Many questions about accuracy of this description are still open. The difficulties are related to presence of resonances. The goal of the proposed thesis is to establish some estimates of the accuracy of the perturbation theory for slow-fast systems in the presence of resonances.

As the technology in the field of computer vision becomes more and more mature, the autonomous vehicles have achieved rapid developments in recent years.

One is that the camera will collect blurred photos when driving at high speed which may affect the accuracy of deep neural networks.

Résumé :

In this study, we consider electrostatics contributed from the molecules in the ionic solution. It plays a significant role in determining the binding affinity of molecules and drugs. We develop the overall framework of computing electrostatic properties for three-dimensional molecular structures, including potential, energy, and forces. These properties are derived from Poisson-Boltzmann equation, a partial differential equation that describes the electrostatic behavior of molecules in ionic solutions. In order to compute these properties, we derived new boundary integral equations and desig

Résumé :

碩士<br>國立交通大學<br>機械工程學系<br>99<br>The frequency estimation for single-tone signal is an important technique for engineering area. DFT (or FFT) is a tradition method to measure the signal’s frequency approximately. However, the estimated frequency usually is not precise because of spectrum leakage and the noisy environment. So, the imprecise frequency is not enough for the application in the engineering area. To improve the precision of the estimated frequency and the robustness in the noisy environment, a lot of frequency estimators have been developed. Gradient search method (GSM) is one of the

Résumé :

碩士<br>國立交通大學<br>電控工程研究所<br>104<br>Robot manipulator have been used for many decades in industrial uses, however, people nowadays still rely on the “teach and learn” method. This is the reason why the specification of robot manipulator only emphasizes on repeatability of pose, instead of the accuracy of pose. Although it somehow meets the requirements in industrial, it is not enough for further applications. For the aspect of CAD–based working, we need robot manipulator with high accuracy of pose in the workspace in order to reach the complicated path. In short, can one robot manipulator reach
