Abstract: A computer implemented method manages execution of jobs on virtual machines. Processor units identify a job for scheduling. The processor units identify host machines with free cores on which the virtual machines are allocated. The processor units determine a number of free cores on the host machines. The processor units determine whether a host machine in the host machines having a number of host attributes needed by the job has free cores and idle cores available for backfilling the job based on a predicted core usage for the job in response to an absence of a sufficient number of free cores being available to meet predicted core usage. The processor units dispatch the job to a virtual machine on the host machine in response to the host machine having the number of host attributes and the free cores and idle cores available for backfilling the job.

Abstract: Through solid dosage minor reduction, the weight percentage of solids in an initial solution of crystallization is reduced in a controlled manner for crystallizing a stevia extract or remaining stevia extract starting material with low steviol glycoside content to obtain crystal steviol glycosides. The solid dosage minor reduction in the crystallization process imparts increased efficiencies to manufacturing processes and enables one or more benefits such as increased particle size distribution of the final crystal product, completion of one or more of solid product isolation processes (e.g., filtration and/or centrifugation) after crystallization, increased dewatering rate in solid product isolation processes, increased speed in subsequent solid drying, and enhanced product purities.

Abstract: A joint link-level and network-level intelligent system and method for dynamic spectrum anti-jamming are provided. The system includes a link-level anti-jamming subsystem and a network-level anti-jamming subsystem. The link-level anti-jamming subsystem sets a reward value as system transmission throughput in a single decision cycle, and a user makes an intelligent frequency usage decision based on the obtained reward value to skip a frequency band in which jamming exists. The network-level anti-jamming subsystem performs reasonable frequency band allocation and management for lower-level sub-users when link-level anti-jamming fails to further enhance a frequency domain anti-jamming capability of the entire system. The users make intelligent frequency usage decisions through a dynamic spectrum anti-jamming algorithm based on reinforcement learning to effectively avoid external malicious jamming, realize dynamic spectrum access, and enhance a frequency domain anti-jamming capability of the system.

Abstract: An unmanned aerial vehicle (UAV) task cooperation method based on an overlapping coalition formation (OCF) game includes: constructing a sequential OCF game model for a UAV multi-task cooperation problem; using a bilateral mutual benefit transfer (BMBT) order that is biased toward the utility of a whole coalition to evaluate a preference of a UAV for a coalitional structure; optimizing task resource allocation of the UAV under an overlapping coalitional structure by using a preference gravity-guided Tabu Search algorithm to form a stable coalitional structure; and optimizing a transmission strategy based on the current coalitional structure, an updated status of a task resource allocation scheme of the UAV, and a current fading environment, so as to maximize task execution utility of a UAV network. The method quantifies characteristics of resource properties of the UAV and a task, and optimizes the task resource allocation of the UAV under the overlapping coalitional structure.

Abstract: The disclosure provides a method, a device and a system for fault detection. The fault detection method includes following steps: acquiring interactive data generated during a working process of a target Internet of Things system, and generating data to be detected based on the interactive data; detecting whether the data to be detected is fault data or not, and performing an emotion analysis on the data to be detected which is judged as the fault data to obtain a corresponding emotion label; and extracting a corresponding fault type from a preset fault emotion mapping table based on the emotion label and outputting the fault type. In this disclosure, the interactive data is analogized to human emotions, and the faults are accurately found through the emotional analysis on the data, thereby achieving the fault detection of the Internet of Things system in a convenient, flexible and accurate manner.

Abstract: Examples described herein relate to reducing a magnitude of a supply voltage for a circuit element of an optical transmitter device. In some such examples, the circuit element is a driving element that is to receive a first electrical data signal and to provide a second electrical data signal to an optical element that is to provide an optical data signal. A testing element is to compare the optical data signal to the first electrical data signal to determine whether the optical transmitter device meets a performance threshold. When the device meets the performance threshold, a regulating element is to reduce a magnitude of the supply voltage of the driving element.

Abstract: One example of a system includes an optical modulator, a push-pull driver, and a compensation circuit. The optical modulator has a nonlinear capacitance. The push-pull driver is electrically coupled across the optical modulator. The push-pull driver charges the capacitance in response to a logic ‘1’ of a level-shifted differential signal and discharges the capacitance in response to a logic ‘0’ of the level-shifted differential signal. The compensation circuit increases the speed of the discharge of the capacitance in response to the level-shifted differential signal transitioning from a logic ‘1’ to a logic ‘0’.

In addition, a phase clock may be coupled to the segment serializer and the timing control of each one of the plurality of segments.
