Application of Three-level Diode-clamped Converter on 10 kW Distribution Voltage Restorer
Energy Procedia, 2013 AbstractThis paper presents the application of three-level diode-clamped converter on 10kW distribution voltage restorer (DVR) for creating compensation voltage. The three-level converter is designed by using IGBT as switching devices and is controlled by using MATLAB/Simulink through dSPACE board.

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion
SmartBot, EarlyView.Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

New Phytologist, EarlyView.Summary Stomata have the crucial role of balancing the uptake of CO2 for photosynthesis and water loss via transpiration by adjusting their aperture. In C3 plants, coordination between photosynthesis and stomatal conductance can be disrupted by mutations in Calvin–Benson–Bassham (CBB) cycle expression, but it is not clear whether the disruption of the ...
