An Atlas of Small Animal Ocular Surgery

為了解決is250規格的問題，作者 這樣論述：

Rick became a Diplomate of the European College of Veterinary Ophthalmologists (DipECVO) in 2007. He is a Spanish national and followed his education in the US and the UK. He obtained a Bachelor’s degree in Biology in St. Thomas Aquinas College, in New York in 1994 and a DVM after attending Ross and

Louisiana State Universities in 1999. He commenced his specialty training in the US and later moved to the EU where he attended the Universidad Autónoma de Barcelona (UAB) to obtain his European veterinary qualification in 2002. Since, Rick obtained his RCVS certificate in ophthalmology (UK) and co

mpleted his residency training at the University of Glasgow and the Eye Veterinary Clinic, in Herefordshire, England, after which he obtained his DipECVO in 2007. Then, he headed the ophthalmology service in a private practice in England from 2006 until 2011. That same year he joined the Royal Veter

inary College of the University of London as a Lecturer to re-launch and lead the new Ophthalmology Service at the Queen Mother Hospital for Animals (QMHA).David graduated from the University of Edinburgh in 1992 and, after a period in general practice, completed a PhD at the University of Cambridge

in the molecular genetics of inherited eye diseases of dogs. Following this he moved to the University of Bristol for a three year clinical residency in veterinary ophthalmology. After this he was appointed Lecturer in Veterinary Ophthalmology at Bristol University Veterinary School, a post that he

held for three years before joining Davies Veterinary Specialists in October 2003 to jointly run their ophthalmology service. He holds both RCVS and European Diplomas in Veterinary Ophthalmology and is an RCVS recognised Specialist in Veterinary Ophthalmology and European Veterinary Specialist in O

phthalmology.

基於金鷹演算法之三階混合全橋LLC諧振轉換器效率最佳化

為了解決is250規格的問題，作者何昆哲 這樣論述：

現今環保意識抬頭，電動車逐漸成為趨勢，用於車用電池充電器等應用場合之功率轉換器需具備大輸出功率、寬輸出電壓以及高功率密度等特點。因此本論文實作一台三階混合全橋LLC諧振轉換器以符合上述應用需求。本論文首先提出一固定工作頻率，調節輔助開關責任週期之控制法，降低控制難度，使電路能工作於二階模式與三階模式，並根據輸出電壓與負載情況進行平滑切換，實現寬輸出電壓與高效率之目標。此外，由於目前文獻中提出之效率最佳化研究皆僅考慮單一負載情境，而轉換器應用於電池充電應用場合時，其負載會隨充電過程而持續改變，針對此一需求，本論文提出一結合LLC諧振轉換器之工作區域分析、損耗分析及金鷹演算法之效率最佳化設計方法

以求解最佳諧振槽設計參數，進而實現最佳綜合效率。本研究最後實際完成一台1250W，輸入電壓500V，輸出電壓360-500V，最大輸出電流2.5A的三階混合全橋LLC諧振轉換器，針對120串ICR-18650M之電池組規格，驗證本研究所提出的控制法與金鷹演算法求得之最佳諧振槽參數的正確性與可行性。由實驗結果可知當輸出電壓500V且輸出80%負載時，所提電路可達最高效率97.3%，且針對實際定電流-定電壓充電法各負載之時間比重進行量測可得綜合效率為95.7%。

Oto-Endoscopy in Small Animal Medicine and Surgery

為了解決is250規格的問題，作者Kureshi, Munir,Bhutta, Mahmood F. 這樣論述：

Ear diseases are one of the most common problems in veterinary medicine, but are often misdiagnosed and mismanaged due to inadequate visualization of the ear. Oto-Endoscopy in Small Animal Medicine and Surgery is written as a practical manual, and outlines the endoscopic approach to diagnosing an

d managing ear disease in small animal practice. It will be of value both to those with limited or no experience of endoscopy of the ear, as well as more experienced practitioners. It discusses set up of the endoscope for ear disease, practical considerations for use, and showcases a range of ear co

nditions diagnosed and managed endoscopically. It also shows use of the endoscope as an adjunct to surgery, either via the ear canal or through the bulla. Each topic and condition is demonstrated using high resolution images, and links to online videos. Edited by Dr Kureshi, a veterinarian with over

two decades of experience in ear endoscopy, and Prof Bhutta, a world renown expert in human ear surgery, makes this a first of its kind, an indispensable reference for basic and advanced practitioners in the field. There is no previous book on ear endoscopy in veterinary medicine, but this is defin

itely an emerging and establishing field. The two lead editors ran the first endoscopic ear surgery course for small animals in the USA in 2021, which was well attended and had excellent feedback. Editors were asked to run the same course in the US in 2022, and are considering running the course in

the UK and Brazil in the near future. They believe endoscope is the gold standard for diagnosis of ear disease, and those utilising such tools in their practice is set to grow. Oto-Endoscopy in Small Animal Medicine and Surgery appeals to dermatologists, internal medicine specialists, surgeons, radi

ologists, and neurologists, and several specialty groups.

LED光偵測用之交指電極單晶矽異質接面光感測器之製造與性能評估

為了解決is250規格的問題，作者陳晏晟 這樣論述：

本論文主要為製造LED光偵測用之交指電極單晶矽異質接面光感測器並進行其性能評估應用於生醫血氧偵測。本研究分別使用本質氫化非晶矽薄膜層作為光感測器之表面鈍化層，N型及P型氫化非晶矽薄膜層作為電子及電洞收集層及於可見光範圍良好吸收的單晶矽晶圓作為光吸收層，完成於可見光波長為300~1100 nm的範圍內的LED光偵測用之交指電極單晶矽異質接面光感測器之研製。本研究成功利用超高頻電漿輔助化學氣相沉積成功研製出具較低內部缺陷的P、I及N型氫化非晶矽薄膜作為交指電極單晶矽異質接面光感測器之關鍵主結構。本研究分別透過四個實驗針對光感測器之圖案外型、ITO厚度、正面及背面氫化非晶矽薄膜I層厚度進行最佳化，

結果顯示C型環形光感測器為最佳外型，I/P、I/N層厚度分別各為10 nm/12 nm、10 nm/20 nm，ITO厚度為100 nm，背面氫化非晶矽I層薄膜厚度為50 nm可獲最佳Ion/Ioff比值，當-1 V偏壓操作下，Ion/Ioff比值從25.5提高至73.3，Ion/Ioff比值明顯提高約188 %。由此顯示影響本研製之交指電極單晶矽異質接面光感測器之Ion/Ioff比值的最重要元件結構為正面本質氫化非晶矽薄膜(I層)厚度。更多的研究細節將會在本文中討論。
