The spatial distribution of discrete sample points from an image affect digital image manipulation. The geometries of the grid lattice and edge are described for digital images. Edge detecting digital filters are considered for segmenting an image. A comparison is developed between digital filters for two different digital image grid lattice geometries -- 8-neighbor grid lattice (rectangular tesselation) and the 6-neighbor grid lattice (hexagonal tesselation). Digital filters for discrete images are developed that are best approximations to the Laplacian operator applied to continuous twoâ d

The ability to filter irrelevant stimuli in order to attend to meaningful sources of information is crucial to all aspects of adaptive functioning, as real-life environments involve innumerable and consistently moving and changing stimuli. This study was designed to examine the ability of children with autism spectrum disorder (ASD) and their typically developing peers (TD) to visually filter potentially distracting task-irrelevant stimuli in order to better process and respond to task-relevant information. A modified version of the flanker paradigm (Eriksen & Eriksen, 1974) was used, in which

Because children are bombarded by an abundance of information from the environment, the development of the ability to filter extraneous information in order to attend to the most relevant information is crucial for optimal information processing. The ability to effectively filter affects every aspect of children's functioning, including educational activities and social interactions. In order to assess the development of filtering with ecologically relevant factors, a forced-choice filtering paradigm in which the target and distracting stimuli were presented at different times was used to meas

Glass fibre reinforced polymer (GFRP) composites are becoming increasingly common place in structural load bearing applications.

The aim of this thesis was to investigate the performance of joints between steel and vinyl-ester GFRP, comparing the tension strength at quasi-static loading rates with that at impact loading rates. The effect of loading rate on the mode II fracture toughness of the GFRP material was also investigated in order to establish a link between the increase in joint strength unde

The formulation is shown to offer a more conservative estimate of maneuverability than traditional energy-based formulations through quantitat

[Truncated abstract] Runoff generation behaviour and flooding in a lake dominated catchment are nonlinear, threshold-driven processes that result from the interactions between climate and various catchment characteristics. A complicating feature of the rainfall to runoff transformation, which may have implications for the flood frequency, is that the various surface and subsurface flow pathways are dynamic, heterogeneous and highly nonlinear, consisting of distinct thresholds. To understand the impact of threshold nonlinearities on the rainfall-runoff transformation in such catchments, a syste

博士<br>國立臺灣大學<br>光電工程學研究所<br>99<br>Subwavelength periodic structures provide two attractive capabilities: controllable filtering effects and synthesis of effective parameters supporting extraordinary physical properties not seen usually in nature; therefore they have been the subject of tremendous research in recent years. The variety of features in subwavelength arrays, such as extraordinary transmission, reflection, and absorption, polarization steering, and nonlinear effects are attributed to resonances. Besides intrinsic material resonances from light-matter interactions, geometrical confi

According to Central Weather Bureau, every year between 1991 and 2006, there were more than 1000 earthquakes measured, thus it is importance to study of the seismic response of earthfill dams. There are many methods for the purpose of seismic response analysis of earthfill dam. The common methods are the pseudo static analysis, finite element analysis and finite difference analysis. Here, the seismic response of Reny

博士<br>臺灣大學<br>電信工程學研究所<br>98<br>The S transform is a powerful linear time-frequency distribution with a progressive resolution. It has been shown useful in various fields of applications. Since it is linear, it filters efficiently in a time-frequency domain by multiplying a mask function. There exist several different inverse algorithms, which result in different filtering effects. The conventional inverse S transform proposed by Stockwell et al. is efficient but suffers from time leakage during filtering. The recent algorithm proposed by Schimmel and Gallart has better time localization durin

The purpose of the present study was to investigate how low-pass filtering and background noise affect the perception of Mandarin tones and initial consonants. Ten subjects (all native Mandarin speakers) listened to Mandarin syllables in varying conditions of background noise and filtering and were forced to guess at which consonant or tone was presented. It was found that low-pass filtering had no effect on the perception of tone, although significant main effects of background noise and tone presented were found and a significant interaction of background noise and tone was found in t

博士<br>臺灣大學<br>電機工程學研究所<br>95<br>Conducted electromagnetic interference (EMI) noise was traditionally classified into two coupling modes, differential-mode (DM) and common-mode (CM). But there were phenomena unexplainable with this traditional theory. An additional noise-coupling mode, the mix-mode (MM), was then proposed to fill this inadequacy. The main focus of this dissertation is to explore the mix-mode noise coupling mechanism even further and use the new understanding to improve practical EMI filter designs. Specifically, three areas were explored. One was to look at the new role in one

An increasing need for effective thermal sensors, together with dwindling energy resources, have created renewed interests in thermoelectric (TE), or solid-state, energy conversion and refrigeration using semiconductor-based nanostructures. Effective control of electron and phonon transport due to confinement, interface, and quantum effects has made nanostructures a good way to achieve more efficient thermoelectric energy conversion. This thesis studies the two well-known approaches: confinement and energy filtering, and implements improvements to achieve higher thermoelectric performance. The
