This paper proposes a feedback-based algorithm for congestion control and bandwidth allocation in the presence of either TCP traffic or both TCP and real-time traffic. In this proposal, the network layer conveys bandwidth and propagation delay measurements to data sources, for instance using IPv6 optional fields. TCP sources use this bandwidthdelay product to control their congestion window, wh...

Atomic force microscopy typically relies on high-resolution high-bandwidth cantilever deflection measurements based control for imaging and estimating sample topography and properties. More precisely, in amplitude-modulation atomic force microscopy (AM-AFM), the control effort that regulates deflection amplitude is used as an estimate of sample topography; similarly, contact-mode AFM uses regul...

In today’s heterogeneous Internet, bandwidth available to TCP flows is often variable. However, current TCP cannot perform optimally under such dynamically varying bandwidth conditions. This paper addresses this problem by introducing a new architecture to improve TCP performance with explicit bandwidth notification (EBN). It uses a normalized bandwidth feedback method to provide accurate and t...

We perform an experimental parametric study of the chaos generated by a laser diode subjected to phase-conjugate feedback. In addition typical figure merit, i.e., bandwidth, corresponding spectral flatness and permutation entropy at delay is analyzed. Our observations reveal that can be with bandwidth $\ensuremath{\approx}29$ GHz, up 0.75, 0.99. These optimized performances are maintained over ...

We investigate reliable multicast communication over satellite networks. We compare a scenario where receivers can use a feedback channel to signal loss to a scenario where no feedback channel is available. We show that the introduction of a feedback channel is the key to allow for bandwidth-eecient, robust, and fully reliable multicast communication via satellite.

By using a quadratic compensation slope, a CMOS current-mode buck DC-DC converter with constant frequency characteristics over wide input and output voltage ranges has been developed. The use of a quadratic slope instead of a conventional linear slope makes both the damping factor in the transfer function and the frequency bandwidth of the current feedback loop independent of the converter’s ou...

Electrochemical seismic sensors are key components in monitoring ground vibration, which are featured with high performances in the low-frequency domain. However, conventional electrochemical seismic sensors suffer from low repeatability due to limitations in fabrication and limited bandwidth. This paper presents a micro-fabricated electrochemical seismic sensor with a force-balanced negative f...

For users with motion impairments, the standard keyboard and mouse arrangement for computer access often presents problems. Other approaches have to be adopted to overcome this. There is evidence to suggest that increasing the degrees-offreedom, and hence bandwidth, of human-computer interaction (HCI), can improve interaction rates if implemented carefully. Haptic feedback is not really exploit...
