Subject to the assumption that sub-barrier fusion is described by an effective one-dimensional energy-independent local potential barrier, the Jeffreys-Wentzel-Kramers-Brillouin approximation for the fusion cross sections is inverted to determine this effective potential. Potential barriers, with their associated experimental errors, are presented for 13C+ 13C and 40Ca+ 40Ca, and the assumption...

In this study, a hybrid method is proposed to investigate the nonlinear vibrations of pre- and post-buckled rectangular plates for the first time. This is an answer to an existing need to develope a fast and precise numerical model which can handle the nonlinear vibrations of buckled plates under different boundary conditions and plate shapes. The method uses the differential quadrature element...

Experimental simulation to a line source has been realized at FNS, JAERI, within the USDOE/JAERI collaborative Program on Fusion Neutronics. This simulation achieved by cyclic movement of an annular Li20 test assembly relative to a stationary point source was a step forward in better simulation of the energy and angular distributions of the incident neutron source found in Tokamak plasmas. Thus...

In this study, silicon carbide (SiC) nanoplates are prepared from the waste quart tube (main composition: dioxide) and autoclave lining polytetrafluoroethylene) produced in laboratory. The reaction is carried a stainless steel at 600 °C through magnesium reduction route. Electron microscopy investigations show that nanoplate thickness of SiC sample about 20 nm, edge length 200 nm. Furthermore, ...

In this article, classical plate theory (CPT) is reformulated using the nonlocal differential constitutive relations of Eringen to develop an equivalent continuum model for orthotropic triangular nanoplates. The equations of motion are derived and the Galerkin’s approach in conjunction with the area coordinates is used as a basis for the solution. Nonlocal theories are employed to bring out the...

This paper presents an objective speech quality measure which is based on loudness patterns using the equivalent rectangular bandwidth (ERB) scale. The proposed measure, called the loudness pattern distortion (LPD), is computed from the differences between the loudness patterns of the original and processed speech. The LPD measure takes into account the transmission through the outer and middle...

Metal–insulator–metal (MIM) waveguides are demonstrated which have electrically pumped semiconductor gain medium at their core. In particular electrical contacts made well away from the optical mode and carriers transported to via pathways a few tens of nanometers thick. Wet chemical etching is employed form cores, can widths on order 150 (nm). Total thickness layers between metal sheets in MIM...

Continuously operating heterogeneous catalytic reactors are an important step towards more efficient and controllable processes compared to batch operation. Ideally, should exhibit high permeability with the catalyst having a surface area volume ratio minimize required amount. An example of such morphology nanoparticles plate-like morphology. In this work, reactor was prepared by depositing sil...
