We consider the evolution of neutron-star (ns), carbon-oxygen white-dwarf (co) binaries, using both the Bethe & Brown (1998) schematic analytic evolutions and the Portegies Zwart & Yungelson (1998) numerical population syntheses. The scenario in which the circular neutron-star, carbon-oxygen white-dwarf binaries (ns, co)c have gone through common envelope evolution is considered. In conventiona...

Spurious eigensolutions in the boundary integral equation (BIE) or boundary element method (BEM) for doublyconnected domain problems, the eccentric and annular membranes, are studied analytically and numerically in this paper. For the mathematical analysis, we employ the null-field integral equation, the degenerate kernels and the Fourier series to prove the existence of spurious eigensolutions...

In this research, residual strength and stress concentration factor of laminated composites with a circular open hole are studied analytically, numerically and experimentally. The numerical study was carried out using the finite element method. Moreover an analytical study was carried out with developing of point stress criterion. Mechanical testing was performed to determine the un-notched ten...

An experiment in forced vibration was conducted to study the fluidinduced rotordynamic force on an impeller whirling along a trajectory eccentric to its undeflected position. The prescribed whi l trajectory of the rotor is a circular orbit of a b e d radius. The force measured is a combination of a steady radial force due to volute asymmetries and an unsteady force due to the eccentric motion o...

Coalescing compact binaries have been pointed out as the most promising source of gravitational waves for kilometer-size interferometers such as LIGO. Gravitational wave signals are extracted from the noise in the detectors by matched filtering. This technique performs really well if an a priori theoretical knowledge of the signal is available. The information known about the possible sources i...
