In this study a Modified Compressible Smoothed Particle Hydrodynamics (MCSPH) method is introduced which is applicable in problems involve shock wave structures and elastic-plastic deformations of solids. As a matter of fact, algorithm of the method is based on an approach which descritizes the momentum equation into three parts and solves each part separately and calculates their effects on th...

A procedure for preparation of semi-activated carbon fiber (SACF) without any treatment under high temperature was proposed. The first step of the procedure is coating of an inorganic fiber (E-glass fiber) by an adsorbent mixture including powder activated carbon, methyl cellulose and water. In this work a set of experiments was performed to attain appropriate adsorbent mixture for good quality...

The Planet-4D model introduced by Baroin 2011b is a richer model of pitch-class relationships than the standard cyclic model of the clock-face diagram: instead of the distribution of twelve points on a circle in a 2D plane, the Planet-4D model places the twelve pcs on a 4D hypersphere. Beyond the usual T/I group of symmetries, which is still featured in this new musical space, the additional di...

Abstract Traditional hydropower generation is one of the most sustainable energy sources; however, local environmental impact hydroelectric dams and reservoirs serious, power requires high-cost turbines generators. Because these installations utilize gravitational potential massive volumes falling water, this sort unsuitable for ubiquitous, small-scale production. Here, we report that wetting e...

Aortic dissection is rare in the pediatric and young adult population. We hereby present a case of a 17-year- old male patient, without any predisposing factors, who developed an aortic dissection. The initial presentation was acute abdominal pain with massive retroperitoneal hematoma. His clinical condition deteriorated rapidly, did not respond to surgical hemostasis, and died within 36 hours ...

This note proves that arbitrary local gates together with any entangling bipartite gate V are universal. Previously this was known only when access to both V and V † was given, or when approximate universality was demanded. A common situation in quantum computing is that we can apply only a limited set S ⊂ Ud of unitary gates to some d-dimensional system. The first question we want to ask in th...

Infective spondylodiscitis is a rare complication that can occur after interventional spinal procedures, of which symptoms are usually back pain and fever. Early diagnosis of infective spondylodiscitis is critical to start antibiotics and to improve prognosis. Laboratory examinations including complet blood cell count (CBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) are...

A novel method to achieve an overlapping illusion without any negative refraction index material is introduced with the help of the optic-null medium (ONM) designed by an extremely stretching spatial transformation. Unlike the previous methods to achieve such an optical illusion by transformation optics (TO), our method can achieve a power combination and reshape the radiation pattern at the sa...

An anonymous bidding protocol without any reliable center for a small community is proposed. The anonymity of a bidding protocol means that the participation of everyone involved in the bidding except for the successful bidder is kept secret. Since it is hard for a small community to establish a reliable center owing to the difficulty and cost of doing so, an anonymous bidding protocol without ...

We investigate chaotic behavior of ordinary differential equations with a homoclinic orbit to a dissipative saddle point under a general time dependent forcing without any periodicity in time. We study Poincaré return maps in extended phase space, introducing a characteristic function that generalizes the classic Melnikov function. We then show that the dynamics of the solutions of these equati...
