Abstract Effect of fine graphite flake, carbon nanotube, and carbon nanofiber additives on the efficiency of an external gear pump driving an ethanol-based closed hydraulic loop was investigated experimentally. A number ...

Freestanding devices fabricated for Microelectromechanical Systems (MEMS) employ slender polysilicon flexures that are prone to failure due to large operating stresses. Polycrystalline silicon (polysilicon) films with ...

The design of supersonic and hypersonic vehicles involves the challenging task of designing thin panels that can withstand severe unsteady pressure and thermal loads. A good understanding and accurate prediction of the ...

An experimental study of the effects of large distributed roughness located near the leading-edge of an airfoil has been performed to determine the effect on boundary-layer development and transition. Boundary-layer ...

The presented work investigates the mechanical response of the silver-copper eutectic system (Ag60Cu40, subscripts indicating atomic percent) linking material deformation to microstructural properties. The Ag60Cu40 material ...

The effects of simulated ice shape on the NLF 0414 were quite different from the NACA 23012m. There was little variation of lift when the simulated ice-shape location was varied from 2% to 20% chord. The large losses in ...

Modeling and predicting the transient behavior of higher dimensional nonlinear dynamical systems subject to Gaussian white noise excitation remains an open problem with broad application to nonlinear estimation, uncertainty ...

In 2004, a research partnership between the University of Illinois and CU Aerospace demonstrated the first electric discharge pumped oxygen-iodine laser referred to as ElectricOIL. This exciting improvement over the ...

Thin film piezoelectric materials with high piezoelectric coefficients such as PbZr0.52Ti0.48O3 (PZT) offer several advantages to microelectromechanical systems (MEMS) due to their low power requirements, large displacements, ...

A drawback to current catalysts used in self-healing materials is the relatively low temperatures at which they deactivate. An advantage of WCl 6 is that the high melting temperature (Tm=275°C) allows for the use of ...
