Membrane contactor using amine based absorbents is an efficient technology for CO2 separation from gaseous mixtures. A novel porous polysulfone (PSF) flat membrane was prepared via non-solvent phase inversion method. The ...

The limiting velocity in open channels to prevent long-term sedimentation is predicted in this paper using a powerful soft computing technique known as Extreme Learning Machines (ELM). The ELM is a single Layer Feed-forward ...

For a long period of time, design and manufacturing technology of high flow rated vertically suspended pumps (VSPs) which have an extensive applications in many industries such as water and wastewater, mining, petrochemical ...

In this article, the failure of a heat exchanger during its operation in the marine environment has been analyzed. This heat exchanger was used for cooling the oil in a marine diesel engine. Based on the existing failure ...

Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was ...

Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this ...

In this work, a multi-objective optimization on novel insulated roof with solar water heating system at low material cost has been carried out through Taguchi based grey relational analysis technique. The novel roofs have ...

Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle ...

V2O5/SiO2 catalyst was utilized to oxidize SO2 to SO3 species in the presence of oxygen mainly for producing sulfuric acid. For this catalyst, the active phase was a mixture of vanadium pentoxide and basic sulfate/pyrosulfate ...

Key Performance Indicator (KPI) is a type of performance measurement that evaluates the success of an organization or a partial activity in which it engages. If during the running process instance the monitoring results ...

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for ...

In order to reduce costs and increase efficiency of a supply chain system, cross docking is one of the most important strategies of warehousing for consolidation shipments from different suppliers to different customers. ...

In this paper, a novel method based on a combination of Extended Kalman Filter (EKF) with Self-adaptive Differential Evolution (SaDE) algorithm to estimate rotor position, speed and machine states for a Permanent Magnet ...

Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. ...
