The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the seco...
The use of static terrestrial laser scanning for the 3D data capturing of smaller scenes as well as airborne laser scanning from helicopters and fixed wing aircraft for data collection of large areas...
The low weight and the relatively low cost of medium format digital cameras have pushed the use of those units for aerial survey. These medium format cameras are often used as secondary sensors togeth...
We investigated the effects of menstrual cycle phase and carbohydrate (CHO) ingestion on immune response during endurance exercise at 30°C. Six healthy women completed 4 trials comprising 90 min of cy...
The objectives of the paper were to evaluate carcass value in reared gilts on the basis of carcass analysis during the station test of purebred progeny of pigs and ultrasonically with Sonomark-100 or ...
Electronic Fuel Control (EFC) valve regulates fuel flow to the injector fuel supply line in the Cummins Pressure Time (PT) fuel system. The EFC system controls the fuel flow by means of a variable ori...
UAVs are becoming standard platforms for applications aiming at photogrammetric data capture. Since these systems can be completely built-up at very reasonable prices, their use can be very cost eff...
针对研制出的液压电机叶片泵样机,建立了电机泵性能试验系统,获得了样机的输入电量参数、输出液压能参数及内部转子转速和壳体内部压力等参数,得到了液压电机叶片泵样机的转子转速、噪声、功率和效率等随输出压力变化的特性,并与同等功率液压电机油泵组的试验结果进行了对比。与电机油泵组相比,电机叶片泵样机的体积减小50%、轴向尺寸减小61%,噪声降低约7 dB,液压电机叶片泵内部转子转速随输出压力升高而明显下降;...
A sampler using inertial fibrous filters (INF) has been recently developed for ultrafine particle collection by impaction and filtration. This new sampler has a low pressure drop (20–30 kPa) and can ...
开发了一种用于ABS电子控制单元室内性能测试的试验台,用于测试其控制功能和故障诊断功能。该试验台主要由轮速再现装置、测控系统、数据采集系统、基础制动系统及恒压油源等组成。台架试验结果表明,试验台能够测试ECU的控制功能。利用该试验台可以方便地设置轮速传感器故障,以实现ECU故障诊断功能的测试。
针对目前水稻联合收获机脱粒分离装置的功耗高、脱出物含杂率高及分布不均匀等问题,研制了一种短纹杆—板齿脱粒滚筒并对其进行了水稻脱粒分离试验。建立了脱粒功耗、脱粒损失、脱出物含杂率与脱粒间隙、滚筒线速度、喂入量之间的数学模型,利用Matlab进行多目标优化,得到了短纹杆—板齿脱粒分离系统的最佳工作参数。试验结果表明,短纹杆—板齿脱粒滚筒在脱粒水稻时功耗较低,脱出混合物含杂率低,分布较均匀,能有效地减小...
The aim of the paper was analysis of changes in range of performance test results of 19782 gilts of Polish Large White conducted in years 1995-2004, produced in Poland in the area activity of Bydgoszc...
