Limits for the performance of communication systems can, in principle, be described by what is called OPTA (optimal performance theoretically attainable) curves. Approaching these limits necessitates large delays and complexities. It can be derived from Shannon's works 22, 23] that the limit can be reached by separately optimizing the source-and channel coders. For existing practical systems th...

While the main objective of adaptive Filter-and-Sum beamforming is to obtain an enhanced speech signal for subsequent processing like speech recognition, we show how speaker localization information can be derived from the filter coefficients. To increase localization accuracy, speaker tracking is performed by non-linear Bayesian state estimation, which is realized by sequential Monte Carlo met...

Several studies have been conducted to develop more accurate and precise indices for hydrocarbons source apportionment. The present study, however, develops a new multi-metric index for hydrocarbons source apportionment. It measures Poly Aromatic Hydrocarbons (PAHs) concentration at six stations with well known petrogenic origin, calculating Phe/An, Flu/Py, Chr/BaA, BaA/Chr, An/(An+Ph), Flu/(Fl...

In this paper, the hybrid photovoltaic-thermoelectric generator (PV-TEG) combined dynamic voltage restorer (DVR) system is proposed for power quality disturbances compensation in a single-phase distribution system. The stable and precise level of input essential smooth trouble-free operation electrically sensitive loads which are connected at utility side to avoid malfunctions. context, PV-TEG ...
