Abstract:

A transient three-dimensional simulation program was developed to study the effects of scanning speed, scanning pattern, blood perfusion, transducer choice and multiple tilted transducers with overlapping foci during scanned focussed ultrasound hyperthermia. The results showed that (1) the temperature fluctuations increase linearly with decreasing scanning speed, (2) the temperature fluctuations are a weak, increasingly exponential function of the blood perfusion rate, and (3) that the largest temperature fluctuation is always located at the acoustical focal depth on the scan path independentl

Abstract:

This dissertation proposes novel solutions for important drawbacks of antenna arrays. One of the main contributions of the presented work is size reduction and nulling performance improvement of traditionally large anti-jam global positioning system (GPS) arrays using miniature antennas and electrically small resonators emulating an engineered metamaterial. Specifically, a miniaturized coupled double loop (CDL) dual band antenna is first introduced as a small antenna element of the compact GPS array. The loops that are capacitively coupled using lumped element capacitor, and employ metallic pi

Abstract:

Multiphoton laser scanning microscopy (MPLSM) is an advanced fluorescence imaging technology which can produce a less noisy microscope image and minimize the damage in living tissue. The MPLSM image in this research is the dehydroergosterol (DHE, a fluorescent sterol which closely mimics those of cholesterol in lipoproteins and membranes) on living cell's plasma membrane area. The objective is to use a statistical image analysis method to describe how cholesterol is distributed on a living cell's membrane.

Abstract:

Analyzing massive-data sets and streams is computationally very challenging. Data sets in systems biology, network analysis and security use network abstraction to construct large-scale graphs. Graph algorithms such as traversal and search are memory-intensive and typically require very little computation, with access patterns that are irregular and fine-grained. The increasing streaming data rates in various domains such as security, mining, and finance leaves algorithm designers with only a handful of clock cycles (with current general purpose computing technology) to process every incoming

In this dissertation we provide a comprehensive theory for the formation of a moire pattern in a sampled halftone image. We explore techniques for restoring a sampled halftone image with a moire pattern and techniques for preventing a moire pattern when a halftone picture is scanned. Specifically, we study the frequency, phase, and spatial geometry of a moire pattern. We observe and explain the half period phase reversal phenomenon that a moire pattern may exhibit. As a case study, we examine the moire patterns generated by a commercial scanner. We propose three restoration methods, including

Abstract:

Scanned focussed ultrasound has been extensively used as a modality to induce hyperthermia for cancer treatment. A major area of research involves determining optimal methods for scanning the ultrasound focus in the tumor. For this research, two new scanning patterns have been designed and implemented in software. The first scanning pattern developed was the circular scan which made use of the rotate and tilt axes of the transducer gantry in an attempt to solve the problem of beam overlap during scanning. The second pattern developed was the yawed octagonal scan which provided more flexibility

Abstract:

Bodies provide important social information, and adults benefit from this information by recognizing and responding appropriately to bodies. Body recognition is enabled by the fact that human bodies are defined by parts, such as the limbs, torso, and head, arranged in a particular configuration. To understand the development of social cognition, it is important to analyze and document how infants come to recognize bodies. Infants are sensitive to distortions to the global configurations of bodies by 3.5 months of age, suggesting an early onset of body knowledge. It was unclear, however, whethe

Abstract:

Epitaxially grown SiGe(C) materials have a great importance for many device applications. In these applications, (strained or relaxed) SiGe(C) layers are grown either selectively on the active areas, or on the entire wafer. Epitaxy is a sensitive step in the device processing and choosing an appropriate thermal budget is crucial to avoid the dopant out–diffusion and strain relaxation. Strain is important for bandgap engineering in (SiGe/Si) heterostructures, and to increase the mobility of the carriers. An example for the latter application is implementing SiGe as the biaxially strained channe

This has resulted in the colour-coded negative space approach, an image preprocessing step that circumvents the need for complicated model fitting or template matching methods.

Abstract:

碩士<br>國立交通大學<br>材料科學與工程系<br>87<br>In this work, nanoscale oxide patterns were fabricated on H-passivated Si substrate by using a scanning tunneling microscope (STM) in air. It was found that the bias voltages, setpoint current and scan line density play important roles to form attainable oxide features. Characterization using AFM and SEM further revealed that the optimum bias voltage applied for patterning is related to the material species of tip rather than to the tip head sharpness. For W tips, oxide patterns with desired geometrical features can be obtained at the bias voltages ranging

This thesis focuses on Gray code and the other two codes obeying Gray Coding Rule with the frequency dispersion characteristics. The goal is to analyze and to improve the encoding and decoding of the proposed codes. The high frequency term in Gray code causes interference, and hence quantization error in decoding is observed. We try to decode Gray code, frequency spread encoding method (Dis16Point_by16), and Gray_by

Abstract:

碩士<br>國立暨南國際大學<br>資訊工程學系<br>98<br>The 3D surface scanning technology has been widely applied in computer vision fields. In the technology, Gray code and Hilbert curves are the two major codes conventionally used. In this study, we focus on the comparison and construction of the simulation of Gray code, Hilbert curves, and the codes under Gray Coding Rule proposed in previous studies. The affect on the performance caused by the high frequency terms in the codes has also been examined, and various decoding rules applied on the codes are proposed and compared. Finally, a group of parameters in a
