(Proceedings of FEDSM2008 2008 ASME Fluids Engineering Conference August 10-14, 2008, Jacksonville, FL, USA, 2008-08-10)In recent years, CFD has become an increasingly used tool in the design of blood-based devices. However, the estimation of red blood cells damage (hemolysis) remains a very important challenge due to the complex rheology ...
-
(2016)In this paper, the energy efficiency (EE) of a cooperative diversity system with maximum diversity network coding (MDNC) is studied. In the considered system, channel state information (CSI) is only available at the ...

(DOI: 10.2514/6.1998-2560 Conference: 29th AIAA Fluid Dynamics Conference, At Albuquerque, NM, USA, Volume: 1, 1998)The generation and early evolution of boundary layer transitional instabilities, named Tollmien-Schlichting (T-S) waves, in airfoil cascade flows are studied. The energy exchange between the mean flow and the flow instabilities ...
-
(International Renewable Energy Congress November 5-7, 2010 – Sousse, Tunisia, 2010-11-05)A pre-feasibility study has been undertaken for the electrification of the rural off-grid village of Hurhudedanda, Nepal. PV solar was deemed most suitable after an assessment of local wind, micro-hydro, solar and biogas ...
-
(International Renewable Energy Congress November 5-7, 2010 – Sousse, Tunisia, 2010-11-05)This work presents a technical and financial pre-feasibility assessment for heat generation from biogas for a retirement home in the community of Peyrelevade, France. The heat demand of the retirement home currently relies ...

(2008-10)Highly productive wells in the Central Eastern Desert of Egypt are tapping groundwater in subsided blocks of Jurassic to Cretaceous sandstone (Taref Formation of the Nubian Sandstone Group) and Oligocene to Miocene ...
-
(2016)In this paper a novel Carrier Aggregation (CA) scheme is proposed for downlink MIMO LTE-A Systems. The proposed approach achieves increased transmission rates by establishing the communication links via both licensed ...
-
(SPE Latin American and Caribbean Petroleum Engineering Conference, Caracas, Venezuela, 21–23 April 1999, 1999-04-21)Experiments are performed to evaluate the leakage vs. pressure drop, wear and fluid properties, in ball-and-seat valves used in pumping units for artificial oil production. The test facility is constructed to evaluate the ...

(III INTERNATIONAL CONGRESS ON COMPUTATIONAL BIOENGINEERING M. Cerrolaza, H. Rodrigues, M. Doublaré, J. Ambrosio, M. Viceconti (Eds.) Isla de Margarita, Venezuela, September 24 to 26, 2007, 2007-09-24)In recent years, CFD has become an increasingly used tool in the design of blood-based devices. Particularly, the estimation of red blood cell damage (hemolysis) becomes an important challenge to CFD scientists since the ...
-
(2010)In this study a comparison of three turbulence closure models (two isotropic and one anisotropic) with experimental data is performed. The interaction between the main channel (MC) flow and the floodplain (FP) generates a ...
