Objective:To study the potential role of subjective visual vertical(SVV)as a prognostic marker for canalith repositioning maneuver(CRM)in patients with posterior canal benign paroxysmal positional vertigo(PC-BPPV)for the Indian ***:SVV was examined in 30 patients with PC-BPPV before and after canalith repositioning maneuver and after complete resolution of *** parameters included the mean of 10 angular tilt readings and direction of deviation,which were compared before and after CRM and following complete resolution of ***:The angle of SVV tilt was greater and deviated towards the affected ear before CRM in all patients,which decreased significantly shortly after CRM and continued to decrease after complete resolution of PC-BPPV(p<0.0001).Conclusions:SVV can be used to test utricular dysfunction in *** angle of tilt improves in response to CRM,which may be used as a prognostic marker in patients with PC-BPPV receiving CRM.

Millimeter Wave and Terahertz Communications: Feasibility and Challenges

引用

ZTE Communications 2012年第4期10卷 3-12页

作者： Phil Pietraski David Britz Arnab roy ravi Pragada Gregg Charlton InterDigital Communications LLC. MelvilleNY 11747 USA AT&T Labs Shannon laboratories Florham ParkNJ 07932 USA InterDigital Communications LLC. King of PrussiaPA 19406 USA

In this paper, the challenges with and motivations for developing millimeter wave and terahertz communications are described. A high-bye candidate architecture is presented, and use cases highlighting the potential applicability of high-frequency links are discussed. Mobility challenges at these higher frequencies are also discussed. Difficulties that arise as a result of high carrier frequencies and higher path loss can be overcome by practical, higher-gain antennas that have the added benefit of reducing intercell interference. Simulation methodology and results are given. The results show that millimeter wave coverage is possible in large, outdoor spaces, and only a reasonable number of base stations are needed. Network throughput can exceed 25 Gbit/s, and cell-edge user throuqhput can reach aDoroximatelv 100 Mbit/s.

Unsteady Flow of a Dusty Visco-Elastic Fluid Through an Incliend Channel

引用

Advances in Pure Mathematics 2011年第4期1卷 187-192页

作者： Geetanjali Alle Aashis.S. roy Sangshetty Kalyane ravi M Sonth Department of Mathematics K.C.T. Engineering College Gulbarga Karnataka India

The present discussion deals with the study of an unsteady flow of a dusty fluid through an inclined channel under the influence of pulsatile pressure gradient along with the effect of a uniform magnetic field. The analytical solutions of the problem are obtained using variable separable and Fourier transform techniques. The graphs drawn for the velocity fields of both fluid and dust phase under the effect of Reynolds number. The velocity profiles for the liquid and the dust particles decreases at different values of time t increases. As the visco-elastic parameter λ increases the velocity of the liquid and the dust particles deceases. When relaxation time parameter σ increases, the velocity of the liquid and dust particles decreases.
