The aim of this research is to study the effect high concentrations salts, pressure and temperature on performance RO membrane with time. Four different (Na2CO3) (5000, 15000, 25000 35000) ppm various pressures such as (1, 3 5) bars at temperatures feed solution (i.e., 25, 35 45) ◦C were used in work. It was found that, concentration salt increase, rejection decrease. While membranes increases ...

Abstract We perform Large-eddy simulations of a non-premixed swirling flame in model combustion chamber with air bulk flow at Re = 15000 and central pilot low-velocity jet methane using the Flamelet-generated manifold model. The unsteady behaviour this regime is well reproduced based on dynamics. distribution turbulent kinetic energy suggests presence intensive vortical structures typical high-...

In this paper we present an approach based on sceneor part-graphs for geometrically categorizing touching and occluded objects. We use additive RGBD feature descriptors and hashing of graph configuration parameters for describing the spatial arrangement of constituent parts. The presented experiments quantify that this method outperforms our earlier part-voting and sliding window classification...

For 7-8% growth rate that India is aspiringfor, its energy needs will increase correspondingly. The challenge is to provide desired quality power in a sustainable manner and at reasonable cost. Small hydropower has the potential of about 15000 MW in India and considered to be a reliable source of electricity generation. Three run-of river small hydropower projects in India has been identified a...

OBJECTIVE To evaluate predicting factors and prevalence of meningitis in patients with first seizure and fever aged 6-18 months old. METHODS This cross-sectional study was performed on 800 patients aged 6-18 months old who had first attack of seizure with fever between March 2005 and March 2012 in the pediatric ward of Ghaem Hospital, Mashhad, Iran. RESULTS Among 800 patients, lumbar punctu...

We investigated the possibility of using several sensing parameters from porous silicon in order to improve gas selectivity. By fabricating porous silicon optical microcavities, three independent quantities can be measured, i.e. the electrical conductance, the photoluminescence intensity, and the wavelength of the optical resonance. We monitored the change of these three parameters as a functio...

An experimental study is performed to evaluate the effect of melt-extract stainless steel fibres on mechanical and flexural properties concrete. A total seventy-two specimens are used determine an optimum fibre dosage plain reinforced Twelve full-scale beam then exposed four-point bending tests. The behaviour beams quantified in this testing. specimen bending, after being subjected 15000 cycles...

We analyse multimodal time-series data corresponding to weight, sleep and steps measurements, spanning 15000 users, collected across consumer-grade health devices by Nokia Digital Health Withings. We focus on predicting whether a user will successfully achieve their weight objective. For this, we design several deep recurrent architectures, including a novel cross-modal LSTM (X-LSTM), and demon...
