In this paper, we address the problem of allocating channels to wireless users in the multiuser-multichannel dynamic spectrum access (DSA) scenario. To solve this problem, we introduce a special form of multi-armed bandit (MAB), named exploration bandit, into DSA for the first time. Two distributed algorithms are proposed to maximize the channel rewards (e.g., transmission rates) of the users. Meanwhile,...
Networked Control Systems (NCS) are becoming increasingly ubiquitous in a growing number of applications, such as groups of unmanned aerial vehicles and industrial control systems. The evaluation of NCS properties such as stability and performance is very important given that these systems are typically deployed in critical settings. This paper presents the Networked Control Systems Wind Tunnel (NCSWT),...
Human error plays a significant role in the failure of fastener-style tubular steel formwork-support(FTSF) during construction. Making full use of site investigation and references, the laws of human error occurrences during construction were gained. The probabilistic models for slip bearing capacity of right-angle couplers with different bolt tightening torques were obtained through experimental...
The space vector pulse width modulation (SVPWM) exhibits unique advantages when applied to Permanent Magnet Linear Synchronous Motor (PMLSM) control systems. In the paper, principle and algorithm of SVPWM and mathematical model of PMLSM are analyzed. Simulation model of Frequency Conversion Timing Control System is set up by MATLAB/SIMULINK for PMLSM based on SVPWM algorithm. This provided a good...
Peer-to-peer (P2P) traffic is arguably the biggest contributor to today's Internet traffic. So far, very limited effort has been paid to theoretically analyze the effect of bringing locality-awareness into P2P applications. In this paper, we analyze three locality-awareness policies for BitTorrent-like system: tracker locality(neighbor selection), choker locality(choking and unchoking) and picker...
