A Shortest Path Heuristic for Evaluating the Quality of Stowage Plans in Roll-On Roll-Off Liner Shipping

ISI-Free Power Roll-Off Pulse

SUMMARY An ISI-free power roll-off pulse, the roll-off characteristic of which is tunable with one power parameter, is proposed. It is shown that the proposed pulse is advantageous in terms of the probability of error for pulse detection in the presence of a timing error among currently known good pulses, among which the raised cosine pulse, " better than " raised cosine pulse, and polynomial p...

Vortex Sheet Computations: Roll-Up, Wakes, Separation

Chorin's vortex blob method has been proposed as a way to extend vortex sheet motion past the singularity formation time, into the physically important roll-up regime. Basic questions are: 1. Does the vortex blob method converge to an infinite spiral as the smoothing parameter tends to zero? 2. Do vortex blob computations approximate real fluid motion? This paper will present and discuss three ...

Compact LPF using T-shaped resonator with sharp roll-off and ultra wide stopband

  In this paper, a microstrip lowpass filter with an ultra-wide stopband with sharp roll-off and compact size is designed and fabricated. To provide a very small dimension, T-shaped and stepped impedance have been used. The cut of frequency at -3 dB is 3.1 GHz. In the proposed structure, insertion loss is less than 0.12 and return loss is more than 15 dB. To achieve a -20dB attenuation level...

Roll-Forward and Rollback Recovery: Performance-Reliability Trade-Off

Trade-O Dhiraj K. Pradhan Nitin H. Vaidya Department of Computer Science Texas A&M University College Station, TX 77843-3112 fpradhan,[email protected] Abstract Performance and reliability achieved by a modular redundant system depend on the recovery scheme used. Typically, gain in performance using comparable resources results in reduced reliability. Several highperformance computers are not...
