Massive parallel business workflows running in the cloud are prone to temporal violations (namely intermediate runtime delays) due to various reasons such as service performance fluctuation and resource conflicts. To deliver satisfactory on-time completion, cloud workflow temporal verification is employed to accurately detect time delays of workflow activities and timely handle temporal violations...
State Grid of China plans to put a ± 500kV/3000MW four-terminal voltage source converter based high voltage direct current (VSC-HVDC) transmission system into operation by 2020. In compare to existing VSC-HVDC transmission systems, this system has higher voltage level and transmission capacity. Accordingly, grid devices and topology would be significantly different. This paper introduces configuration...
Active Reflector is one of the innovations of Five-hundred-meter Aperture Spherical Telescope (FAST), whose performance influences the performance of the whole telescope. To avoid the information acquiring being the bottleneck of the whole process and improve the efficiency of telescope observing, 3DViewer, a program of real-time 3D visualization for Active Reflector System (ARS) of FAST based on...
In order to evaluate the effects of heavy metals discharged in the environment water, a novel method using a glass column packed with eggshell membrane (ESM) as a new adsorption material was developed for the preconcentration of trace Cd in environmental water sample prior to its monitoring by graphite furnace-atomic absorption spectrometry (GF-AAS). The adsorption behaviors of the analyte on ESM...
