In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...

Akamai o ers the largest Content Delivery Network (CDN) service in the world. Building upon its CDN, it recently started to offer High De nition (HD) video distribution using HTTP-based adaptive video streaming. In this paper we experimentally investigate the performance of this new Akamai service aiming at measuring how fast the video quality tracks the Internet available bandwidth and to what...

We propose an adaptive token bucket algorithm for achieving proportional sharing of bandwidth among aggregate flows in differentiated service (DiffServ) networks. By observing the simulation results obtained in a study of the throughput of TCP flows in a DiffServ network, we note that the aggregate flow with a lower target rate occupies more bandwidth than its fair share, while the aggregate fl...

This paper presents the design and Implementation of a novel CMOS Instrumentation Amplifier using capacitive neutralization feedback transconductance techniques for bioelectric signal enhancement. The proposed amplifier also implements indirect current feedback, operating at 3-volt supply. With compact footprint 0.062mm² on chip, achieves an impressive bandwidth 4.2MHz 85 dB CMRR. Implemented 0...

We experimentally and numerically demonstrate a route to bandwidth-enhanced chaos that is induced by an additional optical injection for a chaotic laser diode with optical feedback. The measured and calculated optical spectra consistently reveal that the mechanism of bandwidth enhancement is the interaction between the injection and chaotic laser field via beating. The bandwidth can be maximize...

A very significant result in modern control theory is that, for a linear. finite-dimensional, dynamical system. the state feedback law derived from a quadratic-loss-function niinimisation problem is linear. The paper applies the results of this optimal control theory to a class of problems in which the feedback law is realised by a linear dynamical system. The quadratic loss function of interes...

In Part I of this paper, we presented a scheme for effectively exploiting a noiseless feedback link associated with an additive white Gaussian noise channel with no signal bandwidth constraints. We now extend the scheme for this channel, which we shall call the wideband (WB) scheme, to a band-limited (BL) channel with signal bandwidth restricted to (W , W). Our feedback scheme achieves the well...

A current mode feedback operational amplifier designed using a complimentary MOS circuit technology has been discussed in this paper. A class AB amplifier has been used in the design and the design results in improvement of values of number of parameter when compared to the previously reported architecture. The circuit is designed using 0.35μm technology. Bandwidth of the presented architecture...

Operator perception could be improved by upgrading force feedback devices and adding more senses, such as audio and/or visual. This work is focused on multi-sensorial feedback such as vision, sound, and haptic. The main objective is to determine the most suitable manner to show proper information from the remote environment using devices with a bandwith lower than 30 Hz. The advantage of this d...
