Abstract:

This paper deals with decision problems related to the star problem in trace monoids, which means to determine whether the iteration of a recognizable trace language is recognizable. Due to a theorem by G. Richomme from 1994 [32, 33], we know that the star problem is decidable in trace monoids which do not contain a submonoid of the form {a,c}* x {b,d}*. Here, we consider a more general problem: Is it decidable whether for some recognizable trace language and some recognizable or finite trace language P the intersection R ∩ P* is recognizable? If P is recognizable, then we show that this probl

Recent occupational health studies have focused on dermal exposure at the hands, but have been unable to accurately express dose without knowing the HSA. There is no standard method to calculate HSA, though some researchers have derived HSA formulas based on dimensions from a Taiwanese population.

Nanomaterials have attracted great interest due to the unique physical properties and great potential in the applications of nanoscale devices. Two dimensional atomic crystals, which are atomic thickness, especially graphene, have triggered the gold rush recently due to the fascinating high mobility at room temperature for future electronics. The crystal structure of nanomaterials will have great influence on their physical properties.

We present a two-country New Open Economy Macro model of the Austrian economy within the European Union's Economic & Monetary Union (EMU). The model includes both nominal and real frictions that have proven to be important in matching business cycle facts, and that allows for an investigation of the effects and cross-country transmission of a number of structural shocks: shocks to technologies, shocks to preferences, cost-push type shocks and policy shocks. The model is estimated using Bayesian methods on quarterly data covering the period of 1976:Q1- 2005:Q1. In addition to the assessment of

Challenges of access to education in the developing world and elsewhere appear to be widespread. Many declarations and conventions have been developed to assist countries to respond to the issue. While challenges of access are universal, Africa in general and sub-Saharan Africa in particular are presented with additional concerns about gender equality and gender parity. While learner numbers seem to be on the decline globally, dropout amongst girls is disproportionately greater than amongst boys.

Abstract:

Analog to digital converters (ADCs) are the fundamental building blocks in communication systems. The need to design ADCs, which are area and/or power efficient, has been common. Various ADC architectures, constrained by resolution capabilities, can be used for this purpose. The cyclic algorithmic architecture of ADC with moderate number of bits comes out to be probably best choice for the minimum area implementation. In this thesis a cyclic ADC is designed using CMOS 65 nm technology. The ADC high-level model is thoroughly explored and its functional blocks are modelled to attain the best pos

In the small family of VDAC proteins, composed of three isoforms in chordates, VDAC3 is the least known. Con

Abstract:

A power system stabilizer is an ancillary device used for improving stability of otherwise poorly stable power system. It helps to restore the system back to the operating point after disturbances like load changes or faulty situations are withdrawn or smoother transition from one to another operating point. Originally, power system stabilizers are installed to add damping to local oscillatory modes, which were destabilized by high gain, fast acting exciters. Its property is to provide damping torque to reduce the electromechanical oscillations introduced in the system under disturbances. We a

Abstract:

碩士<br>國立臺灣大學<br>機械工程學研究所<br>102<br>This thesis proposes an automatic large area micro manufacturing system for two-photon polymerization (TPP). This manufacturing system consists of several functions for improving the quality and efficiency of micro-fabrication. First, a 100 micro meters short range 3D piezo stage is fixed on top of a 30 mm long range XY stage, and a software is designed to control both of the two stages for large area micro manufacturing. For fabricating over large area, the precision of autofocus becomes more important. Therefore, optimizing the CMOS camera for enhancing per

博士<br>國立臺灣大學<br>電子工程學研究所<br>103<br>Different approaches are adopted for epitaxially grown large-area 2-D crystals in this thesis. For graphene growth, by using the molecular beam epitaxy (MBE) technique to directly supply carbon atoms during the growth, the growth temperature of the graphene films can be greatly reduced on either metal template or dielectric substrate surfaces. After increasing the carbon source amount by using chemical vapor deposition (CVD) technique, epitaxially grown 2-D crystals such as graphene, MoS2 and MoS2/graphene hetero-structures can be obtained directly on sapphir

Abstract:

碩士<br>國立清華大學<br>電子工程研究所<br>107<br>This thesis describes an analog-to-digital converter (ADC) for FHD image sensors. The ADC specification is 12-bit resolution and the sampling rate is 20 MHz. The architecture of this ADC is two-step successive approximation register (SAR) ADC. The disadvantage of the traditional SAR ADC is the great area of capacitor. When we add every 1-bit resolution, the area of the capacitor will double. In this thesis, the number of unit capacitor of the two-step SAR ADC is reduced to 1/16th of that of a conventional 12-b SAR ADC. The prototype was fabricated using TSMC 0

Abstract:

We examine a class of planar area preserving mappings and give a geometric condition that guarantees the existence of homoclinic points. To be more precise, let $f,g:R \to R$ be $C^1$ functions with domain all of $R$. Let $F:R^2 \to R^2$ denote a horizontal reflection in the curve $x=-f(y)$, and let $G:R^2 \to R^2$ denote a vertical reflection in the curve $y=g(x)$. We consider maps of the form $T=G \circ F$ and show that a simple geometric condition on the fixed point sets of $F$ and $G$ leads to the existence of a homoclinic point for $T$.<br>Thesis (Ph.D, Mathematics & Statistics) -- Que
