leishmaniasis is a common parasitic disease in tropical and subtropical areas of the world. police personnel deployed in the suburbs and rural areas are the most often exposed to the potential risk of cutaneous leishmaniasis. furthermore, since the same police personnel are sent on duty to other places, their migrations can also play a considerable role in the transmission of this disease to th...

This paper is introducing a new controlling scheme with second generation wavelet transform and sandia frequency shift (SFS) for islanding detection of inverter-based distributed generation. This new hybrid method combines two active and passive methods through two performance zones. The new hybrid method calculates energy entropy of wavelet coefficients in its passive zone and if it increases ...

this paper addresses the signal processing principles in passive bistatic radar (pbr) systems. in this case, the detection problem in the presence of system noise, clutter/multipath, direct signal and interfering target signals is investigated. to this light, two types of detectors are studied. in the first one, which is based on intuitive sense, we examine two detectors. in the second type det...

in this paper, we deal with the problem of clutter and direct signal (c&ds;) cancelation in the target detection of tv-based passive radars. we first consider the target detection using the conventional fft method. we see that for increasing the maximum range of passive radar, we must cancel the c&ds; from the received signal. hence, we investigate some important methods for c&ds; cancelation i...

background: this study aimed to survey a total five common human and veterinary antibiotics, including ampicillin, oxytetracycline, enrofloxacin, tylosin, and ciprofloxacin based on spe-lc-ms-ms technology in a wastewater treatment plant at central plateau of iran. also two sampling techniques, passive and grab samplings were compared in the detection of selected antibiotics. methods: in februa...

This article presents a Radial Basis Neural Network (RBNN) based islanding detection technique. Islanding detection and prevention is a mandatory requirement for grid-connected distributed generation (DG) systems. Several methods based on passive and active detection scheme have been proposed. While passive schemes have a large non detection zone (NDZ), concern has been raised on active method ...

Objective Generalized joint hypermobility predisposes some individuals to a wide variety of musculoskeletal complaints, especially in the shoulder joint. Proprioception, which includes joint position sense and sense of movement, has an important role in the functional stability of shoulder joint. Given the critical role of proprioception in the functional stability of shoulder, the primary aim ...

Background: In high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. Here a passive neutron area monitor with CR39 track detector was designed and the response was calculated. Materials and Methods: The response of a passive neutron area monitor with C...
