Laser Epiglottopexy: Flexible versus Line-of-Sight Technique

Positioning Optimization Technique in Non-Line-of-Sight Environment

A positioning optimization technique for non-lineof-sight environment is presented based on weighted orthogonal polynomial fitting technique and singular value decomposition. First, non-line-of-sight errors in TOA measurements are mitigated using weighted orthogonal polynomial fitting technique and the true range between the measuring terminal and the mobile station is approximated. Then the st...

Line-of-Sight Percolation

Given ω ≥ 1, let Z2(ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z2(1) is precisely Z .) Let pc(ω) be the critical probability for site percolation in Z2(ω). Extending recent results of Frieze, Kleinberg, Ravi and Debany, we show that limω→∞ ωpc(ω) = log(3/2). We also prove analogues of this resu...

Coherent Laser Radar Conference Off Line-of-Sight Measurements of Target Vibrational Features Using Laser Vibrometry

Laser vibrometry based on coherent detection techniques allows remote measuring of vibrational target characteristics with high resolution. Previous work concentrated on measurements where a direct line-of-sight between target and sensor was given. In this paper we investigate situations where the target is hidden and out-of-sight, but target-induced vibrations can be captured from the environm...

Laser versus dissection technique of tonsillectomy.

Tonsillectomy is the single most common operation performed in Ear Nose and Throat Department. Various methods of tonsillectomy have been practiced over the century aimed at reducing or eliminating intraoperative and postoperative morbidity. Due to various blood supplies received, intraoperative bleeding is the most difficult problem and securing it is time-consuming. The time taken to control ...
