In this articlewe discuss the differential inclusion known as state dependent sweeping process for a class of prox-regular non-convex sets.We associate with any state dependent sweeping process with such sets an unconstraint differential inclusion whose any solution is a solution of the state sweeping process too. We prove a theorem on the existence of a global solution of nonconvex state depen...

BACKGROUND Sweepers are chronically exposed to dust raised during sweeping. Dust is regarded as the most influential agent and it is perceived as a frequent cause of respiratory system illness and may cause acute and chronic lung function impairment. AIMS The aim of this study was to determine the acute lung function changes in sweepers exposed to dust generated from street sweeping. MATERI...

Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...

INTRODUCTION Here, we evaluated sweeping methods used to estimate the number of immature Aedes aegypti in large containers. METHODS III/IV instars and pupae at a 9:1 ratio were placed in three types of containers with, each one with three different water levels. Two sweeping methods were tested: water-surface sweeping and fi ve-sweep netting. The data were analyzed using linear regression. ...

This paper introduces the recursive sweeping preconditioner for the numerical solution of the Helmholtz equation in three dimensions. This is based on the earlier work of the sweeping preconditioner with the moving perfectly matched layers. The key idea is to apply the sweeping preconditioner recursively to the quasi-two-dimensional auxiliary problems introduced in the three-dimensional (3D) sw...

A temporal electric field profile, which is a radially polarized terahertz (THz) pulse from an electron bunch, was measured by a large-aperture photoconductive antenna (PCA) with micro-structured concentric electrodes for the detection of THz pulses. Photo-induced charge carriers were generated by irradiation of femtosecond laser pulses on semiconductor plane of the electrodes on the PCA. Time-...

This paper presents a light-weight sweeping method, similar to SATand BDD-sweeping. Performance are on the order of 10x to 100x faster than SAT-sweeping for large designs, while achieving about 50-90% of the reductions.

Curling is a sport played on ice in which two teams each deliver 8 granite stones towards a target, or 'house'. It is the only sport in which the trajectory of the projectile can be influenced after it has been released by the athlete. This is achieved by sweeping the ice in front of the stone to change the stone-ice friction and thereby enable to stone to travel further, curl more or stay stra...
