an optical system has been redesigned and used to measure detonation velocity as a function of condensed explosive density for rdx, hmx, petn. these measurements are then used to determine and fine tune parameters appearing in the bkw (beker-kistiakowsky-wilson) equation of state for gases at extremely high pressures. steady state form of conservation equations along with the bkw state equation...

Experience from the ultrasonic inspection of nuclear power plants has shown that large focused transducers are relatively effective in suppressing material structure noise. Operation of a large focused transducer can be thought of as integration (coherent summation) of individual beams reflected from the flaw and received by individual points at the transducer surface. Synthetic aperture focusi...

The Special Affine Fourier Transform or the SAFT generalizes a number of well known unitary transformations as well as signal processing and optics related mathematical operations. Unlike the Fourier transform, the SAFT does not work well with the standard convolution operation. Recently, Q. Xiang and K. Y. Qin introduced a new convolution operation that is more suitable for the SAFT and by whi...

The special affine Fourier transform (SAFT) is an extended version of the classical and incorporates various signal processing tools which include transforms, fractional transform, linear canonical other related transforms. This paper aims to introduce a novel octonion (O−SAFT) establish several classes uncertainty inequalities for proposed transform. We begin by studying norm split energy cons...

Recent theoretical and simulation studies suggest an unexpected shift in the solubility of n-alkanes in nearcritical water, which would indicate that longer n-alkane molecules are more soluble than shorter ones. This trend is contrary to what one finds at ambient conditions, where longer alkanes generally have a lower aqueous solubility. The latter is usually interpreted as a consequence of the...

This paper presents the ability of a new group contribution equation of state in the prediction of thermodynamic properties of alcohols, ketones and ethers. This equation of state, called MCORGC, is based on the Chain-Of-Rotators Group Contribution equation considering a NRTL type local composition mixing rule. The group parameters required to predict the thermodynamic properties of the oxygena...

The general equation of state which was found for dense fluids, both compressed liquids and dense supercritical fluids, namely "Linear Isotherm Regularity," is extended to the lower density range, specifically for densities lower than the Boyle density. This new equation of state which is called "ELIR" is shown to be compatible with the equations of state based on statistical-mechanical the...
