In this paper we propose a new method for estimating parameters in a single-index model under censoring based on the Beran estimator for conditional distribution function. This, likelihood based, method is also used for the bandwidth selection. Hence the proposed method is a useful and simple tool for selecting the bandwidth also for the Beran estimator with one dimentional covariate. Additiona...

The conditions for observing Fano resonances at elastic light scattering by a single finite-size obstacle are discussed. General arguments are illustrated by consideration of the scattering by a small (relative to the incident light wavelength) spherical obstacle based upon the exact Mie solution of the diffraction problem. The most attention is paid to recently discovered anomalous scattering....

آلتراسوند یکی از روش های تصویربرداری است که هیج ضرری برای بدن ندارد، بنابرین نسبت به سایر دستگاه های پزشکی از محبوبیت و کاربرد بیشتری برخوردار است. طراحی بورد front-end یکی از چالشهای بزرگ در طراحی دستگاه سونوگرافی است که در آن سیگنالهای مدوله شده از بدن با دامنه بسیار کم باز می گردند که می توانند در رنج فرکانسی 2 تا 12 مگاهرتز کار کنند. تکنولوژی روز سعی در کوچک کردن مدارهای الکترونیکی و کمینه ...

The removal of copper (II) ion by using ultrasound pre-treatment to increase the pores structure and surface area on peanut husk powder via direct sonication (ultrasound probe) and indirect ultrasound (ultrasound bath) at powder level 3.5 W. In previous studies, researchers had applied ultrasound simultaneous with adsorption process. This method is not suitable to treat huge amount of heavy met...

INTRODUCTION Shoulder injuries are common in baseball players, which may be related to scapular malposition (Burkhart 2003). Although a few studies demonstrated scapular malposition in baseball players using clinical measurement (Laudner 2010, Thomas 2010), no data currently exist that demonstrated 3-dimentional (3D) scapular position and orientation using a technique that eliminates skin artif...

This article describes a visualization tool that helps application developers in understanding/debugging the execution of event-based applications. Vizar allows applications to record and then replay executions of event-based systems. It is a general purpose visualization service. It is not intended or linked in any way to any speciic system { eventhough it was rst targeted for active databases...

A recent particle method, the Local Regularized Rejection Particle Filter L2RPF is applied here in terrain navigation. An aircraft measures periodically the relative elevation. By means of a digital elevation map, the goal is to estimate the absolute position and velocity of the aircraft. Moreover, an inertial navigation system (INS) drives the generation of the particles (fusion of L2RPF and t...

in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...
