"In measurements with cryogenic current comparators (CCCs), robustness against mechanical distortions is an issue. Sources of distortions are part of the experimental environment, efficient suppression is difficult. In a...

"Bone conduction is the transmission of acoustic energy to the inner ear by different paths involving the bones of the skull. In this work, we use the path the hand provides in order to transmit the sound coming from the...

A self balancing system analysis is presented which utilizes freely moving balancing bodies (balls) rotating in unison witha rotor to be balanced. Using Lagrange«s Equation, we derive the non-linear equations of motion ...

Los espectros de infrarrojo de los complejos de Cu(II), bisquelados con los aminoácidos glicina, alanina, leucina, isoleucina, valina y fenilalanina, conocidos por presentar diferentes tipos de actividad farmacológica,...

This article reviews the current status of lattice-dynamical calculations in crystals, using density-functional perturbation theory, with emphasis on the plane-wave pseudopotential method. Several specialized topics are ...
