CONCERTO: readout and control electronics

Journal of Instrumentation, 2022
Abstract The CONCERTO spectral-imaging instrument was installed at the Atacama Pathfinder EXperiment (APEX) 12-meter telescope in April 2021. It has been designed to look at radiation emitted by ionised carbon atoms, [CII], and use the “intensity Mapping” technique to set the first constraints on the power spectrum of dusty ...

A Compensation Algorithm for Large Element Characterizing the Damage Evolution Process and Its Application to Structure Collisions

Chinese Journal of Mechanical Engineering, 2023
When simulating the process from elastic–plastic deformation, damage to failure in a metal structure collision, it is necessary to use the large shell element due to the calculation efficiency, but this would affect the accuracy of damage evolution ...

The Electronic Sitar Controller

, 2004
This paper describes the design of an Electronic Sitar controller, adigitally modified version of Saraswati's (the Hindu Goddess ofMusic) 19-stringed, pumpkin shelled, traditional North Indianinstrument. The ESitar uses sensor technology to extract gesturalinformation from a performer, deducing music information suchas pitch, pluck timing, thumb ...
