The software-defined radio (SDR) paradigmcan be applied to radars. Novel radio-frequency (RF) chains and architectures can lead to enhanced radar schemes. After a brief review of SDR-based schemes, this work concentrates on the relevant topic of impulse-radio ultra-wideband (IR-UWB) radars. By emitting extremely-narrow impulses in time domain, these systems can achieve a great range resolution. However,...
The paper first shows that the transient stability status of a power system following a large disturbance such as a fault can be early predicted based on the measured post-fault values of the generator voltages, speeds, or rotor angles. Synchronously sampled values provided by phasor measurement units (PMUs) of the generator voltages, frequencies, or rotor angles collected immediately after clearing...
Today voting processes are the most important element of democracy as the societies way to make decisions. Such processes have been influenced by information technologies until becoming be named electronic voting. This topic has been an active research area, on which, cryptographic primitives are used in order to propose secure protocols. Most of them use a Public Key Infrastructure. In this paper,...
