Model Predictive Current Control for Low-Cost Shunt Active Power Filter
CSEE Journal of Power and Energy SystemsPerformance of a three-phase shunt active power filter (SAPF) relies on the capability of the controller to track the reference current. Therefore, designing an accurate current controller is crucial to guarantee satisfactory SAPF operation.

Journal of Ultrasound in Medicine, EarlyView.Objectives The femoropopliteal (FP) artery is the most frequently revascularized segment in peripheral artery disease (PAD), followed by the iliac segment. Wall shear stress (WSS) is a key local factor implicated in both atherosclerotic plaque formation and restenosis after angioplasty.

A filter synthesis technique applied to the design of multistage broad-band microwave amplifiers [PDF]
, 2002 A method for designing multistage broad-band amplifiers based upon well-known filter synthesis techniques is presented. Common all-pole low-pass approximations are used to synthesize prototype amplifier circuits that may be scaled in frequency and ...

Laser &Photonics Reviews, EarlyView.A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Polymer International, EarlyView.A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene
