Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Steady Subsonic flows in High Dimensional Nozzle
高维喷管 稳态 亚音速流动
2023/11/15
In this talk, we present our result on subsonic irrotational flows in a multi-dimensional (n>1) infinitely long nozzle with variable cross sections. The flow is described by the inviscid potential equ...
The SAE 2017 High Efficiency IC Engine Symposium combines state-of-the-art presentations with face-to-face networking opportunities for professionals associated with fuel efficiency technologies.
This session will cover recent achievements in the area of advanced high-frequency methods as applied to various problems arising in all branches of high-frequency computational and/or analytical elec...
Artificial muscle for soft robotics:low voltage,high hopes
Artificial muscle for soft robotics low voltage high hopes
2016/8/1
Soft robots do a lot of things well but they’re not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are s...

High-performance photovoltaic cells use semiconductors to convert sunlight into clean electrical power, and transparent dielectrics or conductive oxides as antireflection coatings. A common feature of...
1 100 kV / 1 200 kV断路器大功率试验（High-Power Testing of 1 100 kV / 1 200 kV Circuit Breakers）
特高压（UHV） 试验 短路 标准化 断路器
2010/8/17
特高压（UHV）断路器试验本身就是一项挑战，当前，KEMA已开发了用于超高压和特高压开关设备大功率测试装置。鉴于特高压断路器一般至少由双断口灭弧室组成，需要做验证其正常电流（或故障电流）开断能力的局部试验，可以只针对断路器单断口（即断路器的1/2或1/4）来进行。例如，装有均压电容的瓷柱式断路器的情形就是这样。然而，为满足对金属封闭式开关设备的试验要求（见IEC 61633），在带电部件和外壳之间...
ON HIGH-ORDER POLYNOMIAL HEAT-BALANCE INTEGRAL IMPLEMENTATIONS
heat balance integral high-order polynomial approximants
2009/10/14
This article reconsiders aspects of the analysis conventionally used to establish accuracy, performance and limitations of the heat balance integral method: theoretical and practical rates of converge...
There is a growing need for the use of alternative and renewable energy sources, in terms of sustainable energy development. One of the potentially biggest renewable energy sources in Serbia is agricu...
HIGH ACTIVITY CARBON SORBENTS FOR MERCURY CAPTURE
activated carbons KOH activation surface area
2009/10/13
High efficiency activated carbons have been prepared for removing mercury from gas streams. Starting materials used were petroleum coke, lignite, charcoal and olive seed waste, and were chemically act...
PERSISTENCE OF THE LAMINAR REGIME IN A FLAT PLATE BOUNDARY LAYER AT VERY HIGH REYNOLDS NUMBER
transition flow control boundary layer theory
2009/10/13
Starting from the Navier-Stokes and the continuity equations of a viscous incompressible fluid, a statistical theory is developed for the prediction of transition and break down to turbulence in a lam...

cryogenic refrigerator microelectromechanical systems
2007/2/28
February 15, 2007，A new cryogenic refrigerator has been demonstrated at the National Institute of Standards and Technology (NIST) that operates at twice the usual frequency, achieving a long-sought co...
INFLUENCE OF HIGH PERFORMANCE VOLTAGE CONVERTERS SUPPLY UPON THE INDUCTION MOTORS BEHAVIOUR
Induction motors converters distored regime
2010/1/12
The induction motors supply by converters leads to a distorted regime
accompanied by some parasite torques and some supplementary losses. These aspects
are emphasized further on because their quanti...
