Few Mode Fibers (FMF) and Space DivisionMultiplexing (SDM) are an attractive solution to offer high capacity in optical networks. Although transmission along FMF presents several issues mainly due the cross-talk among modes, use of Multiple Input Output (MIMO) coherent receivers permits limit impact such physical impairment. However, complexity MIMO is not negligible (especially with a large nu...

The evolution of optical network devices such as optical cross-connects and optical amplifiers has provided a huge increase in the transmission capacity of optical links. However, this evolution also brings problems such as the large power imbalance arising with the transmission of several wavelengths that impose a severe degradation to the optical signal. Recent research work shows how to adap...

Infrastructure V2X communication systems are one of the main topics in research domain. Its performance evaluation is an important step before their on board's integration into vehicles and its probable real deployment. Being the first of a series of three publications, this paper studies the physical layer PHY of the upcoming vehicular communication standard IEEE 802.11p. An IEEE.802.11p PHY m...

Metabolic data for normal adult rhesus monkey and human adult retinal vessels are presented for the first time. The Cartesian diver microrespirometer was employed to measure respiration and respiratory quotients. Human retinal arterioles consume oxygen at the rate of 0.5 to 28 nl of oxygen per milligram of dry tissue per hour while the venules consume oxygen in the range of 1 to 27 pi of oxygen...

No quantum key distribution (QKD) protocol has been proved fully secure. A remaining problem is the eavesdropper’s ability to make coherent measurements on the joint properties of large composite systems. This problem has been recently solved by Yao in the case of the security of a quantum oblivious transfer (QOT) protocol. We consider an extended OT task which, in addition to Alice and Sob, in...

In a transparent optical network, a transmitted signal remains in the optical domain over the entire route (lightpath) assigned to it between its source and destination nodes. In this paper, a novel Fuzzy dynamic routing and wavelength assignment technique is proposed for a wavelength division multiplexing (WDM) optical network, to achieve the best quality of network transmission and network se...
