Abstract The prediction of the aerodynamic damping during compressor surge is a challenging task, because flow continuously evolving along four cycle phases: pressurization (PR), flow-breakdown (FB), reversed (RF), and regeneration (RG), complex conditions such as shocks separations occur. Damping predictions with current existing methods typically consist two steps. In first step, modified num...

Over the past few years batch-normalization has been commonly used in deep networks, allowing faster training and high performance for a wide variety of applications. However, the reasons behind its merits remained unanswered, with several shortcomings that hindered its use for certain tasks. In this work we present a novel view on the purpose and function of normalization methods and weight-de...

The target is cylinder with a length = 7 mm and radius = 5 mm. One face of the cylinder is irradiated with a uranium beam having a particle energy of 400 MeV/u. The beam pulse consists of two bunches, each having a full width at half maximum (FWHM) of 80 ns and the total pule duration is 500 ns. The beam focal spot size (FWHM of the Gaussian power distribution in transverse direction) is assume...

the asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. the rigid disk is assumed to be in frictionless contact with the elastic half-space. by virtue of appropriate green's functions, the mixed boundary value problem is written as a dual integral equation. employing further mathematica...

A 20-hour VLBI observation with the NRAO VLBA and GBT in the NOAO Boötes field reaches an rms noise of 9 microJy per beam at 1.4 GHz. Three sources were detected at 10-milliarcsecond resolution within the GBT primary beam of FWHM 8.6, including the 20milliJy calibrator and two sub-milliJy sources. By tapering the visibility data, portions of the VLBA primary beam of FWHM 29 were imaged at poore...

Software often goes through a variety of extensions during its lifetime: adding new fields or new variants to a data structure, retroactively creating new type abstractions, and adding new operations on a data structure. As characterized by the extensibility problem, it should be possible to apply any combination of these types of extensions in any order. Mainstream object-oriented languages, h...
