Abstract:

Cost information is important to all parties in the steel fabrication industry: owners; engineers; and fabricators. The industry is driven by economic forces that encourage the efficient use of material, labour and equipment making cost estimation a vital tool in every decision. Unfortunately, these same forces hinder accurate estimation by imposing economic constraints that reduce the amount of time, effort and money that can be committed to the process; therefore, the development of new and improved cost estimation methods is encouraged. This thesis attempts to demonstrate the feasibility o

Abstract:

Expert computer programs have recently emerged from research on artificial intelligence as a practical problem-solving tool. An expert system is a knowledge-based program that imitates the problem-solving behaviour of a human expert to solve complex real-world problems. While conventional programs organize knowledge on two levels: data and program, most expert programs organize knowledge on three levels: data, knowledge base, and control. Thus, what distinguishes such a system from conventional programs is that in most expert systems the problem solving model is treated as a separate entity ra

A key aspect in Attitude and Orbital Control Systems (AOCS) is the ability to estimateaccurately a spacecraft’s attitude and angular rate. While a classic gyrometer and star-trackerhybridization features high performances, gyroless solutions using only star-trackers as attitudesensors are often chosen to reduce the mission’s cost, when possible. Such an estimation is improvedusing the knowledge of the torque commanded by the spacecraft’s reaction wheels. The torqueestimate is however imperfect, mostly due to friction occurring on the wheels’ shafts. This paperpresents the research undertaken t

One of the primary goals of active research in molecular biology is to better understand the process of transcription regulation. An important objective in understanding transcription is identifying transcription factors that directly regulate target genes. Identifying these transcription factors is a key step toward eliminating genetic diseases or disease susceptibilities that are encoded inside deoxyribonucleic acid (DNA). There is much uncertainty and variation associated with transcription factor binding sites, requiring these sites to be represented stochastically. Although typically each

Abstract:

Bayesian parameter estimation is a popular method to address inverse problems. However, since prior distributions are chosen based on expert judgement, the method can inherently introduce bias into the understanding of the parameters. This can be especially relevant in the case of distributed parameters where it is difficult to check for error. To minimize this bias, we develop the idea of a minimally corrective, approximately recovering prior (MCAR prior) that generates a guide for the prior and corrects the expert supplied prior according to that guide. We demonstrate this approach for the 1

The analysis makes use of complementary variational principles and the superconvergence phenomenon associated with the finite element method. The second part generalizes these results to the important case when the solution of the boundary value problem contains singularities.

Abstract:

Many attempts have been made to quantify cardiac output using both invasive and non-invasive techniques. The results have generally been poorly reproducible and comparisons of techniques have yielded highly variable values. A single breath inert gas method was used in the study, since it offers several advantages over previous methods, chiefly its speed of measurement, and the controlled manner in which it is performed. The method observes the uptake of a semi-soluble inert gas (Freon-22) with respect to an insoluble marker, and calculates cardiac output (pulmonary flow) from the slope of the

Seismic transitions of the subsurface are typically considered as zero-order singularities (step functions). According to this model, the conventional deconvolution problem aims at recovering the seismic reflectivity as a sparse spike train. However, recent multiscale analysis on sedimentary records revealed the existence of accumulations of varying order singularities in the subsurface, which give rise to fractional-order discontinuities. This observation not only calls for a richer class of seismic reflection waveforms, but it also requires a different methodology to detect and charact

ABSTRACT The Novice-Expert ratio Method (NEM) compares the time it takes a novice user to complete each step of a task with the time it takes an expert user to complete the same step. A high ratio indicates that novice users are performing a step far below expert performance. This allows researchers to identify aspects of a user interface that impede its usability, because they are counterintuitive. However, NEM has three major shortcomings. First, the merits of a ratio scale have never been appraised relative to other possible scales, such as log, median, reciprocal, D, and Cohen’s d. Second

碩士<br>國立臺灣科技大學<br>電機工程系<br>103<br>With the advance of multimedia processing technologies and wireless networks, watching live video streaming through the wireless network has become one of the most popular network application services. However, due to instable wireless network transmission, how to provide stable media streaming services is critical for this application. As the live video streaming service requires real-time and stability transsmisoin to provide high-quality perception, some advanced multimedia streaming service systems execute an “available bandwidth estimation (ABE)” proced

Abstract:

碩士<br>東海大學<br>統計學系<br>100<br>Smoothing spline is a popular technique to estimate the hazard function for right-censored lifetime data. When using smoothing spline, selecting the smoothing parameter is an important issue. The cross-validation and generalized cross-validation methods are frequently used to estimate the smoothing parameters. However, these two criteria are not developed for minimizing of the mean square error. In this work, we propose a method based on the Stein’s unbiased risk estimate of the mean square error and the concept of generalized degrees of freedom which are obtained

碩士<br>國立臺灣科技大學<br>電機工程系<br>101<br>With the advance of multimedia communication technologies, real-time video streaming services becomes one of the major digital content services. How to improve the stability for real-time video streaming when many users are requesting the service is very important. To achieve this goal, controlling the network connection topology in an optimal way may help, under which available bandwidth estimation procedure is required. User peers can then be classified by their processing speed and bandwidth capability. The peer interconnection tree can be constructed in an

Abstract:

碩士<br>國立中央大學<br>物理學系<br>105<br>Proton therapy has become one of the most promising radiation techniques for nowadays cancer treatment. A special dose characteristic of proton called as Bragg peak has contributed to spare the dose for normal tissues surrounding cancer. In order to obtain the benefit of Bragg peak, a well-known physics calculation model is needed by treatment planning system to calculate proton dose distribution before it is delivered to the patient. Monte Carlo simulation code is the most used code for the proton simulation. However, different Monte Carlo codes, such as GEANT4,
