LEDs: Sources and Intrinsically Bandwidth-Limited Detectors
The increasing demand for light emitting diodes (LEDs) is driven by a number of application categories, including display backlighting, communications, signage, and general illumination. Nowadays, they have also become attractive candidates as new photometric standards. In recent years, LEDs have started to be applied as wavelength-selective photo-detectors as well. Nevertheless, manufacturers'...
متن کاملLatency- and Bandwidth-Minimizing Optimal Failure Detectors
Failure detectors are fundamental building blocks in distributed systems. Multi-node failure detectors, where the detector is tasked with monitoring N other nodes, play a critical role in overlay networks and peer-to-peer systems. In such networks, failures need to be detected quickly and with low overhead. Achieving these properties simultaneously poses a difficult tradeoff between detection l...
متن کاملWide bandwidth dual acoustic gravitational wave detectors
In a “dual” detector a wideband sensitivity is obtained by measuring the differential displacement, driven by the gw wave, of the facing surfaces of two nested massive bodies mechanically resonating at different frequencies. By the use of the recently proposed “selective readout” scheme, capable of specifically selecting the signal contributed by the vibrational modes sensitive to the gravitati...
متن کاملTurbo Joint Source-Channel Coding of Cycle-Stationary Sources in the Bandwidth-Limited Regime
In this paper we propose a novel one-layer coding/shaping transmission system for the bandwidth-limited regime based on singlelevel codes and sigma-mapping [1]. Specifically, we focus on cyclestationary information sources with independent symbols. High spectral efficiencies can be achieved by combine at the transmitter a Turbo code with a sigma-mapper. Furthermore, the encoded symbols are modu...
متن کاملPixel detectors for diffraction-limited storage rings
Dramatic advances in synchrotron radiation sources produce ever-brighter beams of X-rays, but those advances can only be used if there is a corresponding improvement in X-ray detectors. With the advent of storage ring sources capable of being diffraction-limited (down to a certain wavelength), advances in detector speed, dynamic range and functionality is required. While many of these improveme...
