Remote monitoring of bearing conditions, using wireless sensor network (WSN), is a developing trend in the industrial field. In complicated industrial environments, WSN face three main constraints: low energy, less memory, and low operational capability. Conventional data-compression methods, which concentrate on data compression only, cannot overcome these limitations. Aiming at these problems...

We study compressed sensing (CS) signal reconstruction problems where an input signal is measured via matrix multiplication under additive white Gaussian noise. Our signals are assumed to be stationary and ergodic, but the input statistics are unknown; the goal is to provide reconstruction algorithms that are universal to the input statistics. We present a novel algorithm that combines: (i) the...

For downward-looking linear array (DLLA) three-dimensional (3-D) synthetic aperture radar (SAR), it is necessary to realize the super-resolution in both azimuth and cross-track direction due limited lengths of array. As all scatterers are assumed on uniform grids, can be achieved by 1-D compressed sensing. In real imaging system, however, gridding error should considered because biased lead mis...

Introduction Compressed Sensing (CS) (e.g. [1]) is a novel approach to reconstruct sparse undersampled datasets. Several papers (e.g. [2]) have demonstrated the benefit of CS in the field of MRI. Nonconvex CS [3] is a more recent development which allows for even higher acceleration factors and is easy to implement. A first application for dynamic cardiac imaging has been demonstrated [4]. Howe...

Our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (Nano-CS), for the first time. The second objective was to compare and contrast such penetrations to those of chitosan (CS) itself, as well as sodium hypochlorite (NaOCl), chlorhexidine (CHX) and ethylenediamintetraacetic acid (EDTA), at the routinely used concentrations. Molar roots were split l...

Objective: As the aqueous extract of Capparis spinosa (CS) possess antidiabetic effect, he present study aims to reveal the possible  mechanism of action of CS in diabetic mice.Materials and Methods: Both single and repeated oral administrations of aqueous extract of CS were performed in multi-low dose streptozotocin-induced (MLDS) diabetic mice. Euglycemic hyperinsulinemic clamp was used in as...

The aim of this study was designing and preparing the chitosan nanoparticles (CS-NPs) loading with snake (Vipera albicornuta) venom as well as evaluating the influence of different factors on the encapsulation efficiency (EE) and loading capacity (LC) of venom. The morphologies and characteristics of CS-NPs were determined by scanning electron microscopy (SEM), Fourier transform infrared spectr...

background: around one out of two mothers give births by cesarean section (cs) surgery in iran and about half of this number is due to previous cs. recently health sector evolution (hsep) program (started in april 2014) targets the high rate of cs in iran. to assess the impact of the interventions, we emphasized that the first birth cesarean (fbc) proportion is one of the main indicators to ass...

This paper briefly describes a technique for improving capacity and operational stability of busy mainline junctions and stations. The technique, called the SafeCap advisory system, employs a mixture of existing train monitoring and control technologies to introduce an advisory control layer on top of fixed-block signalling. We present the main design principles and illustrate the advantages of...
