唐兆成博士简介
唐兆成，iSIGHT软件技术发明人；美国易擎公司董事长；赛特达公司董事长Re:Jack Cofer简介
Mr. Cofer began his career at the General Electric Co. in 1974 as a marine turbine requisition and development engineer in the Medium Steam Turbine Department in Lynn, Massachusetts. In 1979 he received the GE Power Systems Sector Engineering Award for Young Engineer in the Industrial and Marine Steam Turbine Division. For more than twenty years, he has provided technical leadership in the development and use of advanced numerical and analytical methods for the design of turbomachinery, with special emphasis on aerodynamics, fluid mechanics, and numerical optimization. He has performed significant work in the aerodynamic design of high efficiency turbine blades and 3-D centrifugal compressor impellers, in the design and testing of downward and axial flow diffusing turbine exhaust hoods, and in the development of advanced numerical methods to optimize the thermodynamic performance of heat recovery steam generators and turbomachinery components.From 1984 to 1996, Mr. Cofer held several management positions at GE in which he was responsible for the development of new, advanced aerodynamic designs for steam turbines for Navy surface ship and submarine propulsion, for commercial power generation, and for mechanical drive applications. In his last position at GE, he was Manager of Aerodynamics Engineering in the Steam Turbine/Generator Technology Department in Schenectady, NY, reporting to the Vice President, Power Generation Engineering. In this position, he was responsible for leading a team of engineers in the development and testing of new high-efficiency turbine and exhaust hood design concepts. He also coordinated steam turbine activities related to the development of new computational fluid dynamics (CFD) computer codes and design automation/optimization tools for use in the aerodynamic design of turbomachinery, and he acted as liaison with the aerodynamics development groups in GE Gas Turbines, GE Aircraft Engines, and the GE Corporate R&D Center. His team was awarded the 1994 GE Industrial & Power Systems Key Business Initiatives Award for the best team effort to improve GE products out of all 25,000 Power Systems employees. He was the champion within GE Power Systems for the use of the Engineous computer-aided optimization software developed at GE’s Corporate R&D Center, and for many years worked closely with Dr. Siu Tong, Engineous Software’s Founder and Chairman, to develop highly successful applications for steam turbine design.
In 1996, Mr. Cofer became Manager of Fluid Mechanics Engineering at Demag Delaval Turbomachinery Corporation in Trenton, NJ. In this position, he and his team were responsible for the development of new, high efficiency designs for steam turbines for mechanical drive and power generation applications, and also for centrifugal compressors for pipeline gas transmission, petrochemical plants, refineries, and many other applications. In 1997, he was named Manager, Research & Development, reporting to the Director of Engineering, and was responsible for all Demag Delaval R&D efforts in Trenton for turbines and compressors. Departments reporting to him included the Computer Systems Department, the Aero/Mechanical Analysis Department, Metallurgy Engineering, and the Engineering Library. In this capacity, he worked closely with other Demag Delaval facilities in Hengelo, the Netherlands, and Dui***urg, Germany.
In March 1999, Mr. Cofer joined Engineous Software Inc. as Director, Turbomachinery & Power Generation. With his 24-year history of using numerical optimization techniques to improve the designs of turbomachinery and power plant equipment, he is uniquely qualified to help turbomachinery and power generation equipment manufacturers around the world improve their products, business performance, and market share through the use of iSIGHT, Engineous Software’s award-winning process integration and design optimization software.
Re:Mr. Wei-Shan Chiang, CTO - FIPER, Engineous Software, Inc.
Formerly Director of Product Development at Engineous. As CTO, Mr.Chiang serves as the key technical advisor on FIPER product strategy and
architecture requirements, he also plays the lead technical liaison to
FIPER-related partnerships and alliances and is the senior consultant to
scope large and complex FIPER projects. With over 16 years of experience
in product development and management, Mr. Chiang has participated in
many government-funded projects including the DARPA DICE project, RaDEO
project, ***D program, and NIST ATP Federated Intelligent Product
EnviRonment (FIPER). Prior to joining Engineous, Mr. Chiang worked in
various technical lead and project management positions at IsoQuest,
Inc., SRA International, Inc., Lockheed Martin Artificial Intelligent
Center, and General Electric Research and Development Center.
