8044 针对这一问题,从用户的角度着手,基于用户行为对云资源调度问题进行深入的研究,提出了基于用户行为反馈的资源调度机制(user behavior-based resource scheduling mechanism with feedback control,UBRSM-FC)。 In order to solve this problem, from the perspective of users, based on user behavior to deeply research the cloud resource scheduling problem, based on user behavior feedback mechanism of resource scheduling (user behaviors - -based resource scheduling mechanism with feedback control, UBRSM - FC).
8045 UBRSM-FC利用用户交互行为,将用户行为信息融入到资源调度过程中,并结合相关反馈机制,建立用户需求的主动发现网络和反馈网络对调度过程不断微调和优化,使资源调度的结果与用户的主观感知更加接近。 UBRSM - FC using user interaction, the user behavior in the process of information into the resource scheduling, and connecting with the relevance feedback mechanism, establish user needs take the initiative to find and feedback network constantly fine-tune the process of scheduling and optimization, the result of the resource scheduling with the user's subjective perception even closer.
8046 实验结果表明,UBRSM-FC通过反馈控制能够更好地满足不同用户不同程度的资源请求,提高了用户满意度,而且能够兼顾系统资源的利用率。 The experimental results show that the UBRSM - FC via feedback control can better satisfy different users different degree of resource request, improve customer satisfaction, and can give attention to both the utilization of system resources.

8053 PASTd算法性能较好,被大量应用于双基地MIMO雷达角度跟踪中,但是PASTd算法不能跟踪相同发射角(direction of departure,DOD)或接收角(direction of arrival,DOA)的目标,并且无法实现不同时刻同一目标角度的自动关联。 PASTd algorithm has good performance and is widely used in bistatic MIMO radar Angle tracking, but PASTd algorithm cannot follow the same emission Angle (direction of departure, DOD) or receiving Angle (DOA) direction of concatenated, goals, and cannot achieve the same target Angle different time automatically.
