A piecewise continuous Timoshenko beam model for the dynamic analysis of tapered beam-like structures [PDF]
Distributed parameter modeling offers a viable alternative to the finite element approach for modeling large flexible space structures. The introduction of the transfer matrix method into the continuum modeling process provides a very useful tool to ...

Continuous loading of an atom beam into an optical lattice
, 2014 I propose a method of deceleration and continuous loading of an atom beam into a far-off-resonance optical lattice. The loading of moving atoms into a conservative far-off-resonance potential requires the removal of the atom's excess kinetic energy. Here

Confining continuous manipulations of accelerator beam-line optics
Physical Review Accelerators and Beams, 2017 Altering the optics in one section of a linear accelerator beam line will in general cause an alteration of the optics in all downstream sections. In circular accelerators, changing the optical properties of any beam-line element will have an impact on ...

Forced vibration analysis of a Timoshenko cracked beam using a continuous model for the crack
Engineering Science and Technology, an International Journal, 2014 In this paper, forced flexural vibration of a cracked beam is studied by using a continuous bilinear model for the displacement field. The effects of shear deformation and rotary inertia are considered in the model.

Non-linear photon subtraction from a multimode quantum field
, 2014 We consider theoretically how to extract mode dependent single photons from a time/frequency multimode non-classical beam. To achieve this task, we calculate the properties of sum frequency generation with a pulse shaped pump, taking into account both ...

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
