This work presents a novel bird-shaped broadband piezoelectric energy harvester based on a click here two-DOF crossed beam for low-frequency environmental vibrations.The harvester features a cantilever mounted on a double-hinged beam, whose rotating motions effectively diminish its natural frequencies.Numerical simulation based on the finite elemen
The outburst of the COVID-19 pandemic and its rapid spread throughout the world in 2020 shed a new light on mathematic models describing the nature of alarecre.com epidemics.However, as the pandemic shocked economies to a much greater extent than earlier epidemics, the recovery potential of economies was emphasized and its inclusion in epidemic mod
Palmer amaranth is a relatively recent arrival in Western Nebraska, where acetolactate synthase (ALS)-inhibitor-resistant biotypes are common in the region.With limited effective postemergence (POST) herbicides for controlling ALS-inhibitor-resistant Palmer amaranth in dry edible bean, a sequential preemergence (PRE) followed by (fb) POST program o
This paper proposes three novel feature extraction approaches for human activity recognition in videos.The proposed solutions are based on video coding concepts including motion compensations and coding based feature variables.We use these features with deep learning for model generation and classification, hence the ViCo-MoCo-DL abbreviation which
