As the key control component of water hydraulic systems, proportional valve has a significant influence on performance systems. Due to poor viscosity and lubricity water, spool resistance is large non-linear. In this study, novel fast-response presented. The actuator adopts voice coil motor (VCM), which advantages fast response, high precision small volume. order realize valve, lever amplifier ...

We investigate several properties of a translocating homopolymer through a thin pore driven by an external field present inside the pore only using Langevin Dynamics (LD) simulations in three dimensions (3D). Motivated by several recent theoretical and numerical studies that are apparently at odds with each other, we estimate the exponents describing the scaling with chain length (N) of the ave...

Bidirectional path tracing (BPT) and photon mapping (PM) are probably the two most versatile physically based rendering algorithms available today. It has been acknowledged that BPT and PM are complementary in terms of the types of light transport effects they can efficiently capture. Our recently proposed vertex connection and merging (VCM) algorithm aims to leverage the advantages of both met...

Objetivo: Mensurar o volume máximo de oxigênio (VO2Máx) corredores rua, com e sem uso máscaras proteção individual. Metodologia: A pesquisa ocorreu a participação 21 idade entre 18 54 anos, ambos os gêneros, que praticam modalidade há pelo menos um mês. As dobras cutâneas foram medidas fim determinar percentual gordura corporal - %G, para mensurar VO2Máx, realizou-se teste do Banco McArdle. O f...

BACKGROUND This study aimed at evaluating the effect of application of different patterns of positive ventilatory pressure either during or after cardiopulmonary bypass (CPB), on lung functions. METHODS 30 patients undergoing coronary artery revascularisation under the management of CPB were randomly allocated into 3 groups. Group I (VCM) 10 patients were subjected to manual vital capacity ma...
