Abstract: We have built and exercised a simple, veridical, macroeconomic model which displays growth and cycles as well as the influence of monetary and fiscal policy. Features of the model comprise a ...

Abstract: Compressible flow in channels of slowly varying cross section at moderately high Reynolds numbers is treated in the paper by employing some Stewartson-type transformations that convert the problem ...

Abstract: The surface hardening of a number of different austenitic alloys by thermochemical treatment and their subsequent behavior to unlubricated sliding wear is described. It is shown that nitriding, ...

Abstract: The propagation of weak discontinuities along bicharacteristic curves in the characteristic manifold of the differential equations governing the flow of a radiating gas near the optically thin ...

Abstract: This paper describes a theory for the approximated analytical determination of pressure distribution in the gap of a generic finite length journal bearing in isothermal laminar lubrication ...

Abstract: This paper reports a theoretical analysis and experimental investigation of pulse tube refrigerator. A concept of steps is introduced for the derivation of cold end temperature with zero heat ...

Abstract: The propagation of long internal waves over two-dimensional topography is discussed. A two-dimensional version of the Korteweg-deVries equation is derived with variable coefficients which depend on the local fluid depth. ...
