This paper presents a model-based control approach for output feedback stabilization and disturbance attenuation of continuous time systems that transmit measurements over a limited bandwidth communication network. Necessary and sufficient conditions for asymptotic stability of the networked system in the presence of persistent external disturbances are given. The results in this paper provide ...

Mobile wireless video delivery is still challenging due to its limited bandwidth and dynamic channel status. In this paper, a novel approach named Dubbing Video Slides (DVS) is proposed to cope with the bandwidth limitation problem. Based on a statistical video content importance analysis, DVS method can dynamically select and transmit representative video frames which are relatively more impor...

Nowadays, multimedia streaming is a common service on the Internet including both fixed and mobile networks. The RTP protocol is usually used to transfer the media. The RTCP protocol is an accompanying protocol for the RTP and it is used for feedback transmission in order to control multimedia session behaviour. The issue is the bandwidth dedicated for the RTCP protocol. As defined in the RTP s...

Various roles for operators in human-machine systems have been proposed. The proposed research hypothesizes that underlying all of these views is the law that operators perform best when given feedback of the same type as their intent. To test the hypothesis, operator performance with position control, rate control, and position control with the ghost arm will be measured to see if giving posit...

ABSTRACT: Miller compensated OTAs are generally used for frequency stabilization. With increasing in gain of cascaded OTA the frequency response decreases in terms of gain bandwidth product and phase margin. To increase the gain at differential stage of OTA, a positive feedback is applied which increases gain without decreasing the gain bandwidth product and phase margin. The above prototype is...

To minimize QoS degradations during nonstationary packet loadings, predictive rate schedulers adapt the operation according to anticipated packet arrival rates deduced via specified estimation algorithm. Existing predictive rate schedulers are developed under the assumption of perfect estimation, which may not be possible in future CDMA-based cellular networks characterized with highly nonstati...

In order to improve the bandwidth allocation considering feedback of operational environment, adaptable bandwidth planning based on reinforcement learning is proposed. The approach is based on new constrained scheduling algorithms controlled by reinforcement learning techniques. Different constrained scheduling algorithms,, such as “conflict free scheduling with minimum duration”, “partial disp...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...

as wireless networks with high data rate get widely deployed, improving the performance of tcp over these networks plays vital role. wireless link losses have dramatic adverse impact on tcp performance due to the difficulty in distinguishing the congestion losses from wireless link losses. we first, studied the various existing bandwidth estimation algorithms over the wireless networks. in this...

the aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. for this purpose, first, an exact mathematical model of phase locked loop (pll) based frequency synthesizer is described and analyzed. then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. based on this formula, the phase ...
