A Zenith Z-100 Emulator
… software emulations of the system. A Z-100 emulator is considered to be complete if it runs all functions of its monitor ROM BIOS program and is able to boot and run its two operating systems. One reason previous emulation attempts are not complete is that they ineffectively implement the …

Design of A Variable-Stiffness Ankle-Foot Orthosis Emulator
Ankle-foot orthoses (AFOs) are passive devices used to improve gait in children with cerebral palsy. They are characterized by a torsional stiffness and ankle neutral angle. For this project, a lightweight ankle exoskeleton was designed to emulate the spring-like behavior of a traditional AFO for a …

Nanocontacts controlled atom-by-atom in an ion-crystal friction emulator
Friction is the basic, ubiquitous mechanical interaction between two surfaces that results in resistance to motion and energy dissipation. To test long-standing atomistic models of friction processes at the nanoscale, we implemented a synthetic nanofriction interface between a laser-cooled Coulomb …

Design and development of a traction motor emulator using a three-phase bidirectional buck-boost AC-DC converter
… with a power electronic converter based ‘Motor Emulator’ (ME) test-bench system. The conventional ME comprises of two-stage three-phase AC-DC-AC conversion with first-stage AC-DC as emulator and second-stage DC-AC as regenerating unit. This two-stage power conversion, require independent control …

Experimental Investigation of Liquid and Gas Fueled Flames Towards the Development of a Burning Rate Emulator (BRE) for Microgravity Applications
Laminar steady burning on flat plates was studied at various orientations with respect to gravity. Flat wicks were saturated with methanol or ethanol. Steady flames were obtained, and ranged from boundary layer flames to plume-type burning. Maximum burning rate per unit area was recorded at an …
