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...

This paper introduces the recursive sweeping preconditioner for the numerical solu4 tion of the Helmholtz equation in 3D. This is based on the earlier work of the sweeping preconditioner 5 with the moving perfectly matched layers (PMLs). The key idea is to apply the sweeping precondi6 tioner recursively to the quasi-2D auxiliary problems introduced in the 3D sweeping preconditioner. 7 Compared ...

The first direct experimental evidence of the suppression of quasi-two-dimensional turbulence by mean flows is presented. The flow either is induced externally or appears in the process of spectral condensation due to an inverse cascade in bounded turbulence. The observed suppression of large scales is consistent with an expected reduction in the correlation time of turbulent eddies due to shea...

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...

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...

The internal heat transfer performance and flow structures of a sweeping jet film composite cooling on flat plate were numerically studied. Sweeping consists fluidic oscillator 20 cylindrical holes; the direct is formed by removing feedback from oscillator, which different traditional nozzle. Four mass rates coolant considered, inclination angle hole was 30°. Conjugate Heat Transfer method (CHT...

continental slope. Historically, four mechanisms have been suggested (or assumed): (1) eddies shed from the ACC, (2) flow into the cross-shelf-cutting canyons with overflow onto the nominal shelf, (3) general upwelling, and (4) episodic sweeping of ACC meanders over the shelf. The mooring array showed that for the years of deployment, the dominant mechanism is eddies; upwelling may also contrib...

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. ...
