Direct Numerical Simulations (DNS) are carried out to study the channel flow V-shaped roughness on both wall. The roughness is modeled by the immerse boundary method for passive heat transport in a turbulent channel flow ...

One of the most important aspects of controlling a robotic manipulator is the solution of its Inverse Kinematics problem. Numerical methods, although more computationally challenging than algebraic or geometric methods, ...

Microfluidic devices have become a great tool to target biological cells individually. They are easy to manufacture, involve short time assays, use small sample and reagent volumes, and usually have low Reynolds number ...

Al-Cu composites reinforced with diboride particles were fabricated by gravity casting. A thermomechanical analysis (TMA) system allowed studying hardness and creep behavior of the composites. The composite hardness was ...

Sandwich composites are increasingly being used in the ship hull design due mainly to (i) their high strength to weight ratio, and (ii) the ability to functionally grade them for a broad range of commercial and naval ...

Electroporation, or electropermeabilization, is a physical phenomenon that occurs when a biological cell is subjected to an external electric field. This technique is typically used in laboratory or medical settings when ...

Phase changes materials (PCMs) have been studied as passive cooling alternative for different conditions. Due to the US Army need for the development of a passive cooling system alternative for pulsed power applications, ...

The Regional Ocean Modeling System has been implemented in the San Juan bay estuary, Puerto Rico, to investigate quantitatively the ocean currents at a harbor scale with tidal, wind and river forcing and to develop a ...

The aerospace industry has focused on the development of high performance polyimide foams because these materials are known for their thermal and acoustic insulation properties. Tortuosity is defined as a parameter that ...

A damage detection location scheme for structures is developed with the use of singular value decomposition and a matrix norm. Damage is represented as a reduction in stiffness producing a set of linear differential ...
