German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and Laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence
ORL人臉庫(Olivetti Research Laboratory人臉數據庫),誕生于英國劍橋Olivetti實驗室。ORL人臉數據庫由該實驗室從1992年4月到1994年4月期間拍攝的一系列人臉圖像組成,共有40個不同年齡、不同性別和不同種族的對象。每個人10幅圖像共計400幅灰度圖像組成,圖像尺寸是92×112,圖像背景為黑色。其中人臉部分表情和細節均有變化,例如笑與不笑、眼睛睜著或閉著,戴或不戴眼鏡等,人臉姿態也有變化,其深度旋轉和平面旋轉可達20度,人臉尺寸也有最多10%的變化。該庫是目前使用最廣泛的標準人臉數據庫,特別是剛從事人臉識別研究的學生和初學者,研究ORL人臉庫是個很好的開始。
電力系統是一個大規模、時變的復雜系統,在國民經濟中有非常重要的作用。電力系統數字仿真已成為電力系統研究、規劃、運行、設計等各個方面不可或缺的工具,特別是電力系統新技術的開發研究、新裝置的設計、參數的確定更是需要通過仿真來確認。目前常用的電力系統仿真軟件有:(1)邦納維爾電力局(Bonneville Power Administration,BPA)開發的BPA程序和EMTP(Electromagnetic Transients Program)程序;(2)曼尼托巴高壓直流輸電研究中心(Manitoba HVDC Research Center)開發的PSCAD/EMTDC(Power System Computer Aided Design/Electromagnetic Transients Program including Direct Current)程序;(3)德國西門子公司研制的電力系統仿真軟件NETOMAC(Network Torsion Machine Control);(4)中國電力科學研究院開發的電力系統分析綜合程序PSASP(Power System Analysis Software Package);(5)MathWorks公司開發的科學與工程計算軟件MATLAB(Matrix Laboratory,矩陣實驗室)。
