Abstract: An approximate mathematical model for the static, no-load (blocked receiver) operation of a fluidic amplifier employing axisymmetric jets is developed. The amplifier is similar in concept to the ...

Abstract: Closed-form expressions in terms of elementary functions are derived for the elastic field resulting from spherical Hertz contact of isotropic bodies. Shear traction is also included using a ...

Abstract: This paper addresses approximately 15 years of advanced technology programs sponsored by the United States Army Aviation Applied Technology Directorate and its predecessor organizations and conducted ...

Abstract: A variety of innovative financing techniques for highway and transit is reviewed. With federal support diminishing and transportation needs growing, agencies are seeking new ways to fund transportation projects. The ...

Abstract: Highly disordered, ion-processed silicon is studied using a molecular dynamics simulation with empirical interatomic potentials. The surface free energy density, stress-strain relations, and continuum ...

Abstract: Carbon nanotubes are a material system of increasing technological importance with superb mechanical and electrical properties. It is well known that depending on details of atomic structure, ...

Abstract: Mechanistic pavement design procedures based on elastic layer theory require the specification of elastic moduli for each material in the pavement section. Repeated load tests yielding a resilient modulus are frequently ...

Abstract: Models are used to represent and characterize physical phenomena. When there are many plausible models for a particular phenomenon, the modeler can exploit the computational tool called model falsification to systematically ...

Abstract: A 3D numerical model, validated with data from field and laboratory measurements, is applied to simulate the flow in a 7-km-long reach of the Columbia River, upstream from Wanapum Dam, Wash. As a tool for analysis and ...
