In this tutorial paper, we present the application of well-known DSP techniques used in lower speed wireline and wireless applications, to high-speed optical communications. After an introduction on today’s optical network architecture and typical optical channel impairments, we study techniques such as fiber equalization, maximum likelihood detection, and current and next generations Forward E...

We studied the effect of vibratory stimulation of different leg muscles [bilateral quadriceps (Q), hamstring (HS) muscles, triceps surae (TS), and tibialis anterior (TA)] in seven normal subjects during 1) quiet standing, 2) stepping in place movements, and 3) walking on the treadmill. The experiments were performed in a dimly illuminated room, and the subjects were given the instruction not to...

We examined the gliding flight performance of a jackdaw Corvus monedula in a wind tunnel. The jackdaw was able to glide steadily at speeds between 6 and 11 m s(-1). The bird changed its wingspan and wing area over this speed range, and we measured the so-called glide super-polar, which is the envelope of fixed-wing glide polars over a range of forward speeds and sinking speeds. The glide super-...

Since car manufacturers pursue in the development of environmental -friendly vehicle, the demand for extensive research on stability, controllability, and reliability of electric vehicles (EVs) increases. Electric powered and by-wire control technology allow manufacturers to build independent four -wheel steering of an allwheel drive in-wheel EV. In past research, we investigated the advantages...

Planing hulls, commonly used in many areas, have different hydrodynamic behavior than the displacement even calm water. Therefore, this makes calculation of maneuvering parameters these hulls appealing. In present study, a planing hull's numerical static drift analyses are performed using unsteady RANS approach to evaluate sway force and yaw moment at angles attack advance velocities. The resul...

Results are presented of a benchmark study organised by the ISSC-ITTC Joint Committee on global linear wave loads container ship with forward speed. The aim is assessment uncertainty in transfer functions due to different seakeeping codes and consequences long-term extreme vertical bending moments. Seven institutes participated benchmark, fifteen codes, representative theories use nowadays. Thr...

This letter addresses the problem of steering a robotic vehicle along geometric path specified with respect to reference frame moving in three dimensions, termed Moving Path Following (MPF) motion control problem. The MPF is solved for large class vehicles that require minimum positive forward speed operate. restriction poses additional challenges design, and developed using concepts, wherein a...
