Inverse synthetic aperture radar (ISAR) imaging of a maneuvering target is a challenging task in the field of radar signal processing. The azimuth echo can be characterized as a multi-component polynomial phase signal (PPS) after the translational compensation, and the high quality ISAR images can be obtained by the parameters estimation of it combined with the Range-Instantaneous-Doppler (RID)...

Building applications from of-the-shelf pieces, like libraries and components, is a promising approach to the future of software development. As such pieces are a subject to reuse, they have to have their interfaces and semantics clearly defined. To combine components from various vendors, one need a way to reason about component compatibility. Our experience with distributed component-based ap...

Abstract Maghemite nanoparticles prepared with the modified synthesis method published by Sun et al. 2004 and followed filtering to extract a sample of smallest nanoparticle size were investigated. The 2-5 nm monocrystalline multi-twinned morphology without surface shells observed. Superparamagnetic behavior was detected above temperature 40 K. An exchange bias loop shift ~ 2 mT at 3 K after co...

a few of the presented soil behavior models are capable of predicting the triggering and post liquefaction and also shear band mechanism through the soil media. the assessment of earth-dam body behavior as a soil structure made of cohesive soil in core and non-cohesive soil as the core supports, including water interaction at upstream through earthquake upon a multi-line constitutive equations ...

A fast time-varying discharge model with safety system capabilities has been extended to handle the accidental release of multi-component mixtures. Previously the model could only handle pure components or “pseudo-component” mixtures, but the new multi-component model carries out vapour-liquid equilibrium (VLE) calculations. This allows accurate predictions of the phase envelope between a mixtu...

The freezing phase transition in a binary suspension of conoidal hard spheres of diameter ratio a = 0.61 was studied by light scattering and scanning electron microscopy. The suspensions consisted of stericaHy stabilized poly( methyl methacrylate) spheres of diameters about 670 and 407 nm suspended in a near refractive indexed matched suspension medium composed of carbon disulphide and cis-deca...
