In 2019, he was the recipient of the American College of Cardiology D

istinguished Service Award.Dr. Dunbar Ivy began his medical career at Tulane University School of Medicine following his premedical studies at Davidson College. While at Tulane, he became excited about a career in Pediatric Cardiology under the mentorship of Dr Arthur Pickoff. He then obtained train

ing in General Pediatrics at the University of Colorado School of Medicine in Denver, Colorado. Early mentors in Pediatric Cardiology included Drs. Michael Schaffer and Henry Sondheimer. Interest in altitude related illness and pulmonary hypertension in congenital heart disease were fostered by Dr R

obert Wolfe on the clinical side and Drs Steve Abman and John Kinsella in the fetal sheep laboratory while a fellow in Pediatric Cardiology at the University of Colorado. Following fellowship, he became a research instructor under the guidance of Dr Mark Boucek, who encouraged him to pursue a career

as a clinician scientist. During his time as a Bugher fellow, he obtained early grants from the March of Dimes and American Heart Association regarding the role of endothelin in the perinatal pulmonary circulation. This work transitioned into a National Institutes of Health K-08 award to continue t

o study molecular derangements in the endothelin pathway in models of pulmonary hypertension. In 2003 Dr Ivy took the position of Chief of Pediatric Cardiology and Selby’s Chair of Pediatric Cardiology. His research focus became more clinical and translational. As Director of the Pediatric Pulmonary

Hypertension Program, he began early clinical studies of medical therapy in children, including the use of intravenous epoprostenol, subcutaneous treprostinil, and oral bosentan. He began to work with Dr Robin Shandas regarding measurement of right ventricular afterload in children with pulmonary h

ypertension in an NIH sponsored Specialized Centers of Clinically Oriented Research grant headed by Dr Kurt Stenmark. Further work on ventricular vascular coupling has continued with NIH funding. Dr Ivy was the inaugural Chairman of the first Pediatric Pulmonary Hypertension taskforce at the World S

ymposium of Pulmonary Hypertension in Nice, France in 2013. Dr. Ivy is a member of multiple societies, and has published over 250 peer reviewed manuscripts.Dr. James Jaggers was born and raised in Western Nebraska. He completed medical school at the University of Nebraska Medical Center in Omaha Neb

raska. He then completed General Surgery at the Oregon Health Sciences University in Portland Oregon and Thoracic Surgery training at the University of Colorado Health Sciences Center in Denver, where he also completed a Pediatric Cardiac Surgery Fellowship at The Childrens Hospital In Denver. From

there, his first Faculty position was as assistant professor of Surgery at Duke University Medical Center where he rose to the rank of Associate Professor with tenure and Chief of Pediatric Cardiac Surgery and Director of the Duke Pediatric Heart Institute. During his time as chief of Pediatric Card

iac Surgery at Duke, Dr. Jaggers directed the pediatric cardiovascular surgery laboratory and mentored many research fellows. He was principal and co-principal investigator on two basic Science NIH grants and one Pediatric Heart Network NHLBI sponsored multicenter study. In 2010, Dr. Jaggers moved t

o the University of Colorado and Children’s Hospital Colorado where he is now the Barton Elliman Chair of Congenital Cardiac Surgery and Professor of Surgery. Dr. Jaggers’s Clinical focus is in all areas of Congenital Cardiac Surgery including complex neonatal repairs, single ventricle surgery, hear

t transplantation and surgery for connective tissue disorders. He has special interest in quality, safety and effective care for children. He is also the program director for the University of Colorado’s Congenital cardiac surgery training program. His research interests include Stem cell delivery t

o improve heart function in children with complex congenital heart disease, and laboratory research in investigation into the protein signaling of aortic stenosis and uncompensated cardiac hypertrophy and myocardial dysfunction. Dr. Jaggers is a member of multiple Societies, and has published over 1

40 peer reviewed manuscripts, published 30 book chapters and is a reputed national and international educator and lecturer.

多軸⾶⾏器強化學習控制

為了解決Altitude的問題，作者畢楨煥 這樣論述：

本論⽂討論使⽤強化學習控制法則進⾏多旋翼無⼈機的⾶⾏控制。在控制⽅⾯，提出⼀種基於強化學習的低階控制器和兩種改進⽅法，使多旋翼控制器性能⽐⼀般強 化學習控制器具備更通⽤性以及強健性。本研究從四旋翼機構建模和模擬環境的構建 開始，基於神經網路的四軸⾶⾏器控制器經由強化學習演算法，產⽣⼀控制策略來調 節四旋翼⾶⾏器的⾶⾏。其中四旋翼機的環境狀態做為神經網路的輸⼊，⽽四個轉⼦ 的推⼒作為控制輸出。此四旋翼控制器可歸類為⼀⾮線性控器，並且只需透過定義⼀ 個損失函數來作為控制策略的最佳化⽬標，此提出的⽅法顯著簡化四旋翼控制器的設 計過程。為了驗證多旋翼控制策略的結果，本研究除了在系統模擬環境中對策略進

⾏ 訓練和驗證，也在實驗部分通過控制閉迴路結構將控制策略應⽤於真實的多旋翼⾶⾏ 器，本⽂將訓練好的強化學習控制策略實現於機載⾶⾏電腦，並且觀察與討論此控制 策略應⽤在現實世界中多旋翼⾶⾏器的可⾏性和⾶⾏表現。 針對強化學習控制器的通⽤性，本論⽂提出了⼀種多⽤途控制⽅法。通過修改神經網路的輸⼊和輸出，該⽅法可以克服強化學習控制器只適⽤於於特定模型以及特定 物理參數問題，解決耗時以及⾼成本控制器訓練。在強健性⽅⾯，本論⽂提出了⼀種 具有擾動補償的強化學習控制結構，以解決外部擾動下的四旋翼定位問題。所提出的 控制⽅案構建了⼀個⼲擾觀測器來估計施加在四旋翼三個軸上的外⼒，例如室外環境 中的陣⾵。通過在

Vampire Boys: True Tales from Operators of the Raf’s First Single-Engined Jet

為了解決Altitude的問題，作者Bailey, Charlotte 這樣論述：

Sliding out of the shadows of World War Two, the de Havilland Vampire - accompanied by the distinctive whine of its Goblin engine - quickly proved itself an effective alternative to piston-powered fighters. After entering operational service with the RAF (as the service’s first single-engined jet) i

n 1946, the Vampire - sought by air forces the world over - held a number of notable records: the first fighter to exceed 500 mph, the first to set a world altitude record of almost 60,000 ft, the first jet to take off and land from an aircraft carrier, and the first jet to cross the Atlantic Ocean.

Not bad for something built partly of wood. Throughout these pages, the ’Vampire Boys’ bring to life the trials and tribulations of operating a first-generation jet across the globe. Through their insightful anecdotes and exceptional experiences, the reader can follow squadrons across the dusty des

erts of Iraq to exercises in West Germany. First-hand tales of training, aerial handling, incidents and accidents (including the much-maligned spin characteristics) and squadron life - accompanied by unique images - bring together a portrait of a pioneering time in aviation advancement, right up to

the present day with the T.11 still flying from Coventry Airport.
