MIT engineers have developed a telerobotic system to help surgeons quickly and remotely treat patients experiencing a stroke or aneurysm. With a modified joystick, surgeons in one hospital may control...
This research explores the use of PM2.5 gird derived from remote sensing for assessing the effect of long-term exposure to PM2.5 (ambient air pollution of particulate matter with an aerodynamic diamet...
Pen gesture interfaces have difficulty supporting arbitrary multiple-stroke selections because lifting the pen introduces ambiguity as to whether the next stroke should add to the existing selectio...
We present Zone and Polygon menus, two new variants of multi-stroke marking menus that consider both the relative position and orientation of strokes. Our menus are designed to increase menu breadt...
We investigated the link between heat stroke and high air temperature from July to September in 2010 in Fukushima prefecture, Japan. Daily data of ambulance transports stratified by heat stroke and th...
This paper focuses on the development of an optimized photovoltaic tracking system involving low-cost, relative simple mechanisms, with linear actuators able to insure strokes comparable with those re...
根据弹塑性力学理论,分析了T型导轨翘曲矫正过程中所经历的弹性加载、弹塑性反弯和卸载回弹这3个变形阶段,推导了各个阶段的矫正载荷、弯矩和行程间的关系,给出各变形阶段的载荷-行程关系式,从而建立T型导轨翘曲变形矫正的载荷-行程模型。利用该模型,可根据导轨的初始翘曲挠度快速、准确地计算出相应的矫正行程。为验证该模型的正确性,以T89/B型导轨为例进行了实验对比分析,其结果表明该理论模型与实验所得出的矫正...
The main objective of the present work is to make a computational study of stratified scavenging system in two-stroke medium capacity engines to reduce or to curb the emissions from the two-stroke eng...
Considering the energy crises and pollution problems today, investigations have concentrated on decreasing fuel consumption by using renewable alternative fuels and on lowering the concentration of to...
The paper reports a theoretical investigation into various aspects of cold forming through conical converging die at the end of stroke. At this stage of the process, there occur some phenomena that re...
Zein was treated by thermolysin and Proleather, the latter a mixture of proteinases from Bacillus sp. The corresponding products were called SD-ZT and DA-Pro, respectively, The hydrolysates resulting ...
综合利用Matlab/Simulink、Chemkin、电磁场有限元法对HCCI自由活塞式内燃发电机建立了仿真模型。分析了系统的运动特征,阐明了它与传统内燃机运动规律的差异。讨论了变负荷、燃空当量比下自由活塞式内燃机的变压缩比特性。仿真结果表明,自由活塞式内燃发电机能够根据外部参数调节压缩比,当工作在高压缩比下时,有利于提高燃烧效率、降低内燃机排放。
Two stroke spark ignition engines have high exhaust emissions and low brake thermal efficiency due to the short circuiting losses and incomplete combustion, which occur during idling and at part load ...
Robotic brace aids stroke recovery     Robotic  Medicine       2007/3/29
March 20, 2007,At age 32, Maggie Fermental suffered a stroke that left her right side paralyzed. After a year and a half of conventional therapy with minimal results, she tried a new kind of robotic t...
Twenty-one polycyclic aromatic hydrocarbons (PAHs) from a four-stroke motorcycle were collected with a micro-orifice uniform deposit impactor and measured in size-segregated particulate samples of 0...
