Non-line-of-sight underwater optical wireless communication network.
The growing need for ocean observation systems has stimulated considerable interest within the research community in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. Sensors and ad hoc sensor networks are the emerging tools for performing extensive data-gathering operations on land, and solutions in the subsea setting are being sought. Eff...
متن کاملOptical Holonomic Quantum Computer
In this paper the idea of holonomic quantum computation is realized within quantum optics. In a non-linear Kerr medium the degenerate states of laser beams are interpreted as qubits. Displacing devices, squeezing devices and interferometers provide the classical control parameter space where the adiabatic loops are performed. This results into logical gates acting on the states of the combined ...
متن کاملAn Optical Data -Flow Computer
For many applications, such as signal and image processing, computer vision, and artificial intelligence, the current achievable performance is much lower than that needed. Von Neumann models cannot achieve computational rates equivalent to billions of operations per second that will be required for these applications. Therefore, parallel models of computation must be used. One attractive conce...
متن کاملAn Optical Brain Computer Interface
An optical brain computer interface (OBCI) is a device, which translates physiological measures of thought processes, derived through optical interrogation techniques, into control signals capable of driving external computers independent of the peripheral nervous system. The optical method used in our current system is near-infrared spectroscopy. An optical window at 650-900nm allows light, wi...
متن کاملBugs in sight
What is the worst thing about an academic career? The bureaucracy. Since becoming a parent time has become particularly precious to me, yet I seem to spend so much of my time in meetings and filling out forms that I am almost too busy to tell anyone how busy I am — and that’s even before doing any research! I have learned to adapt by switching my mind rapidly in and out of work mode when requir...
