Microelectromechanical systems (MEMS) are becoming more prevalent in today’s space technologies. The Visible Nulling Coronagraph (VNC) instrument, being developed at the NASA Goddard Space Flight Center, uses a MEMS Mirror to correct wavefront errors. This MEMS, the Multiple Mirror Array (MMA), will enable the VNC instrument to detect Jupiter and ultimately Earth size exoplanets. The MMA ...

The high luminosity large hadron collider (HL-LHC) project aims at increasing the integrated luminosity by a factor of 10 from its original value (from 300 to 3000 fb-1) leading to the potential extension of scientific discoveries. To attain this goal, important upgrades will take place in the LHC by 2024 including the installation of new superconducting magnets in which new beam screens will be ...

Isogrid plate components are widely used in aerospace structures because of their greater stiffness to weight ratios compared with thicker plates of the same material. Isogrid plates consist of flat plates conjoined with thin ribs in specific geometric patterns. The purpose of this study was to investigate the applicability of COMSOL Multiphysics for the determination of buckling loads and modes ...

Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet these requirements, we designed, using COMSOL, a small, easy to read MEMS capacitive force sensor, with ...

Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is developed to simulate the microwave drying process. An elaborate experimental system comprising of infrared ...

Describing and predicting the extent of the physicochemical processes as well as geometrical deformation taking place during food transformation is of major importance to control food functional properties. Unfortunately, only a few food-matrix models consider deformation particularly because of large deformation. In the case of a starchy product such as rice, water transport and swelling ...
