Photo-sensitive Structures with Cascade Radiation Concentrators Based on Colloidal Quantum Dots of Metal Chalcogenides

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. The problem of increasing the efficiency of existing photodetectors and creating their new types attracts much research attention. Among new photodetector types are photosensitive structures based on cascade concentrators, whose operational

An Adaptive Backstepping Sliding-Mode Control for Improving Position Tracking of a Permanent-Magnet Synchronous Motor With a Nonlinear Disturbance Observer

open access: yesIEEE Access, 2023
To provide reliable position control for a permanent-magnet synchronous motor (PMSM) under conditions of lumped disturbances such as external load torque fluctuation and system parameter variation, an adaptive backstepping sliding-mode control (ABSMC ...

Induction Motor Improved Vector Control Using Predictive and Model-Free Algorithms Together with Homotopy-Based Feedback Linearization

open access: yesEnergies
Vector control of an induction machine (IM) is typically performed by using cascade control structures with conventional linear proportional–integral (PI) controllers, the inner loop being designed for current control and the outer loop for rotor flux ...

Trophic cascades induced by lobster fishing are not ubiquitous in southern California kelp forests. [PDF]

open access: yesPLoS ONE, 2012
Fishing can trigger trophic cascades that alter community structure and dynamics and thus modify ecosystem attributes. We combined ecological data of sea urchin and macroalgal abundance with fishery data of spiny lobster (Panulirus interruptus) landings ...
