As New Zealander geophysicist Gillian Turner’s book North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth’s Magnetism [1] shows, our planet’s magnetic properties have intrigued people since a...

We explore how the internal structure of a test particle affects its equatorial stable circular orbits around Kerr black hole with or without cosmological constant. To this end, we first explicitly write equations motion for in pole-dipole-quadrupole approximation specifying quadrupole momentum tensor to spin-induced model. Then calculate characteristic quantities -- radius, angular momentum, e...

the present study investigates the crystal preferred orientation (cpo) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (ebsd) on quartz crystals from north of the renvyle-bofin slide (rbs) nearletterfrack in western ireland. complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

This paper presents a new procedure for the speed changing of the twospeed compressor driven by the singlephase Permanent Split Capacitor (PSC) motor. The use of the two-speed motor for compressor is one of the effective ways for their capacity control. But the two speed compressors now in use are driven by three-phase motors. It is because a single-phase, two-speed motor has rather a small sta...

A common problem in speaker identification systems is that a mismatch in the training and testing conditions sacrifices much performance. We attempt to alleviate this problem by proposing new features that show less variation when speech is corrupted by convolutional noise (channel) and/or additive noise. The conventional feature used is the linear predictive (LP) cepstrum that is derived from ...
