A Critical Review on the Book Plato: Deconstruction of a Philosophical Myth by Hassan Fathi

“…Vakili’s Plato is a stony aristocrat, an ambitious treacherous, and deviator of the Persian theoretical and practical teachings. Vakili introduces very historical pieces of evidence from Greek-Persian relations to validate his portrait, but after reading his book, it is not hard to say that he lacks a comprehensive, original, and deep understanding of Plato’s teachings. …”

Experimental research on a direct-detection optical OFDM system based on cascaded variable coefficient training sequences and pre-emphasis technique by Wei WU, Jiang-nan XIAO, Ming CHEN, Jian-jun YU, Lin CHEN

“…Frequency selective fading (FF)caused by digital to analog converter and optical fibe dispersion in optical fiber link was analysed,and signal-signal mixing interference (SSMI) when the orthogonal frequency division multiplex-ing (OFDM) signal was detected by PIN after transmitting over the fiber in direct-detection optical OFDM system.The cascaded variable coefficient training sequences and pre-emphasized configuration of O-OFDM signal were proposed to decrease the influence of the SSMI and FF.The theoretical analysis and experimental results show that the receiving sen-sitivity of the cascaded variable coefficient training sequences and pre-emphasized configuration of OFDM signal is higher than the interleaved configuration of training ed that the fiber transmission performance of the cascaded variable coefficient training sequences and pre-emphasized configuration of O-OFDM signal is better than the interleaved configuration of training sequence of OFDM signal in ro-bust tolerance against SSMI and FF.…”

A Study on the Usage of Cross-Layer Power Control and Forward Error Correction for Embedded Video Transmission over Wireless Links by Fabrizio Granelli, Cristina E. Costa, Aggelos K. Katsaggelos

“…However, most available solutions are based on empirical considerations, and do not provide a theoretical background supporting such approaches. The paper aims at providing an analytical framework for the study of single-hop video delivery over a wireless link, enabling cross-layer interactions for performance optimization using power control and FEC and providing a useful tool to determine the potential gain deriving from the employment of such design paradigm. …”
