本篇論文的目的,在提出以電腦輔助設計(Computer Aided Design) 來簡化設計過程
。同時製作一個小型的繪圖核心系統(GKS,Graphical Kerrel System) 作為電腦輔助
設計的基本繪圖工具。
電腦輔助設計部分,是用Bezier Curve 的Fitting Mode,所以使用者祇要將所要曲線
上的已知數點,透過本系統的Point Editor 輸入電腦,就可以逼近想要的曲線。這些
曲線用來設計一件物體的剖面和切面,再利用一、曲面旋轉,二、直軸設計和三、自
然軸設計,這三種設計方法,就可以將想要的物體,以網狀線條顯示在螢光幕上。當
然,一件完整的物體,有時是好幾件更小的物體所組成的,所以本系統提供管理物體
之間的資料結構的功能,使用者可以單獨地設計物體各部份,再銜接起來,成為一個
複雜、完整的個體。
繪圖核心系統部份,是依據Clnternational Standards Organization (ISO) 所定的
國際標準,而設計的一套繪圖系統,在這套系統中,所有的繪圖指令如畫線等都經過
標準化,而趨向一致,使繪圖系統和機器硬體無關,增進系統的可攜性。
以上這些功能,都己經IBM-PC 上,用C Language 設計完成

4H-SiC detectors for low level ultraviolet detection
Ultraviolet radiation covers the wavelength from 400nm down to 10nm. The superior material properties of 4H-SiC make visible-blind, ultra sensitive and low noise UV photodetectors possible.
The major objective of this Ph.D. thesis research is to design and fabricate high performance 4H-SiC photodetectors for low-level UV detection. Schottky photodiodes, avalanche PIN photodiodes and avalanche phototransistors are studied for various applications.
In this study, the first 4H-SiC Schottky photodiode that can fully cover EUV to NUV range has been successfully fabricated. Ultralow leakage current, high quantum efficiency and high UV-to-visible rejection ratio have been achieved. The first 1x16 4H-SiC Schottky photodiode array with very large detection area has been successfully fabricated and characterized. A novel UV spectrographic system using the 4H-SiC Schottky photodiode array is demonstrated with a fine spectrum resolution.
4H-SiC single photon avalanche photodiode (SPAD) is studied for UV single photon detection. In this work, many challenging issues including bevel edge termination and ohmic contact have been addressed. The 4H-SiC SPADs show high gain, low dark count rate and good single photon detection efficiency (SPDE). The best 4H-SiC SPAD shows a high counting efficiency of 79% and 32.5% with a dark count rate of 125.3 kHz and 38.8 kHz at -119.4 V and -119 V, respectively. The first 4H-SiC SPAD array has been successfully fabricated and characterized. Only 1 pixel out of 33 pixels shows high leakage and high dark count rate. For all the good pixels working at -119.5V, the gain is greater than 106, the dark count rate is less than 100 kHz and the SPDE is more than 2%. The proton irradiation impact to 4H-SiC single photon avalanche diodes is investigated for the first time.
A novel 4H-SiC avalanche phototransistor structure is also studied in this research. The first 4H-SiC avalanche phototransistor is demonstrated with an optical gain greater than 4.5x104.Ph.D.Includes bibliographical references (p. 147-155)
Can AI Bridge the Literacy Gap? Developing a GPT-4 Summarization Tool for Low Literacy
In the Netherlands, 2.5 million adults grapple with low literacy—a gap between integration and an increasingly information-densesociety. To address this, we have developed an innovative intervention using GPT-4, integrated within the user interface built via Streamlit, to summarize and simplify the complexity of official documents and everyday text. This paper outlines the design and anticipated functionality of our tool, which uses the summarization capabilities of GPT-4 to trans complicated language into concise, accessible content with clear action points and connect with related organizations. Six participants were invited to this study. We evaluate the tool’s impact on enhancingform the societal participation of adults lacking basic skills, proposing that such an application can empower low-literacy individuals and bridge the gap to an informed and equitable society
