Due to the advantages of cloud computing, it has been adopted as deployment platform of SBS (Service-based Systems). It also provides an elastic "pay-as-you-go" mode, which creates new resource allocation challenge that satisfying the QoS (Quality of Service) requirements with least resource allocation. There has been much interest in using feedback control to make resource allocation, but...
This paper presents a novel on-line path planner for multiple UAVs based on the distributed planning scheme and the bi-level programming technique, in the presence of diverse surface-to-air missiles (SAMs) deployed within large operational spaces. With a formal problem formulation, the planner offers a hierarchical architecture that not only provides global convergence and optimized solution for the...
Thermal issue is one of the major challenges in the research field of three-dimensional (3D) IC. Network-on-Chip (NoC) has been viewed as a practical communication infrastructure for 3D IC. To facilitate such research, an accurate and non-proprietary environment for simulating the NoC traffic and temperature is necessary. In this paper, we present a traffic-thermal mutual-coupling co-simulation platform...
Software aging refers to the phenomenon that applications will show growing failure rate or performance degradation after longtime execution. It is reported that this phenomenon usually has close relationship with computing-resource exhaustion. This paper analyzes computing-resource usage data collected on a LAN, and quantitatively investigates the relationship between computing-resource exhaustion...
From October 2008 the interconnection between northeast and north power grid switched from alternating current to direct current. It is urgent to research the stability of northeast power grid based on the real network data. This paper studied the stability changing by applying real-time time-domain simulation method and frequency-domain analysis method. Research result indicated that the stability...
Adaptive software testing is the counterpart of adaptive control in software testing. It means that software testing strategy should be adjusted online by using the testing data collected during software testing as our understanding of the software under test improves. Previous studies on adaptive testing rely on a simplified Controlled Markov Chain (CMC) model for software testing which employs several...
