We present a new algorithm to compute small node separators on large, undirected graphs ensuring a user defined balance on the induced connected components. Our algorithm uses edge separators computed by the open source graph partitioning package KaHIP [42] and a new technique to transform them into node separators. Given an undirected graph G, our algorithm constructs a flow problem on a subgr...

A validated multi-physics numerical model that accounts for charge and species conservation, fluid flow, and electrochemical processes has been used to analyze the performance of solar-driven photoelectrochemical water-splitting systems. The modeling has provided an in-depth analysis of conceptual designs, proof-of-concepts, feasibility investigations, and quantification of performance. The mod...

The article provides a brief analysis of the internal diameter and capacity vertical gravity separator. process separation should be understood as separating solid, liquid vapor phases in stream. Devices which solid are separated from gas called separators. Separators used condensate mines divided into classes according to their different qualities. following types (classes) purpose: a) working...

Polarization, solution-separator, charge transfer, and diffusion resistances of clean and used separator electrode assemblies were examined in microbial fuel cells using current–voltage curves and electrochemical impedance spectroscopy (EIS). Current–voltage curves showed the total resistance was reduced at low cathode potentials. EIS results revealed that at a set cathode potential of 0.3 V di...

A direct expansion (DX) HVAC system is an efficient way to supply fresh and dehumidified air to a built environment. To improve the efficiency of a conventional DX system in hot and humid regions, fresh air dehumidification and conditioning systems with energy recovery measures are the key equipment to reach such a goal. To achieve this goal an integrated system is proposed. The integrated syst...

     Diurnal air temperature modeling is a beneficial experimental and mathematical approach which can be used in many fields related to Geosciences. The modeling and spatio-temporal analysis of air Diurnal Temperature Cycle (DTC) was conducted using data obtained from 105 synoptic stations in Iran during the years 2013-2014 for the first time; the key variable for controlling the cosine term i...
