Response Spectrum Analysis of the Domestic Piston of Reciprocating Compressor Based on ANSYS

Shiyou jixie, 2017
To evaluate the working performance of the domestic piston on reciprocating compressor, taking the crankshaft connecting-rod movement to the dead point as study object, analyses on the modal and response spectrum of the piston and piston rod have been ...

Tuning the mobility of a driven Bose-Einstein condensate via diabatic Floquet bands

, 2013
We study the response of ultracold atoms to a weak force in the presence of a temporally strongly modulated optical lattice potential. It is experimentally demonstrated that the strong ac-driving allows for a tailoring of the mobility of a dilute atomic ...

IVOA Recommendation: Simple Spectral Access Protocol Version 1.1

, 2012
The Simple Spectral Access (SSA) Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectra. SSA is a member of an integrated family of data access interfaces altogether comprising the Data Access Layer (DAL) of ...

Wave localization in strongly nonlinear Hertzian chains with mass defect

, 2009
We investigate the dynamical response of a mass defect in a one-dimensional non-loaded horizontal chain of identical spheres which interact via the nonlinear Hertz potential.

The CRIRES Search for Planets Around the Lowest-Mass Stars. I. High-Precision Near-Infrared Radial Velocities with an Ammonia Gas Cell

, 2010
Radial velocities measured from near-infrared spectra are a potentially powerful tool to search for planets around cool stars and sub-stellar objects. However, no technique currently exists that yields near-infrared radial velocity precision comparable ...

An approximate procedure for estimating seismic demands for buildings

MATEC Web of Conferences, 2017
Methods of the estimation of the seismic demands of nonlinear structures require a sort of iterative procedures, no matter the elastic or inelastic response spectra are used in the procedure. Many studies dealt with the development of different inelastic
