Attention mechanism has been widely believed as the key to success of vision transformers (ViTs), since it provides a flexible and powerful way model spatial relationships. However, is attention truly an indispensable part ViT? Can be replaced by some other alternatives? To demystify role mechanism, we simplify into extremely simple case: ZERO FLOP parameter. Concretely, revisit shift operation...

Understanding the aging mechanism for lithium-ion batteries (LiBs) is crucial optimizing battery operation in real-life applications. This article gives a systematic description of LiBs electric vehicle (EV) First, characteristics common EVs and chemistries used these applications are described. The then classified into three modes: charging, standby, driving, which subsequently Finally, behavi...

This study explains the breakdown mechanism in different triggered spark gap switches. Two different trigger electrode configurations are tested for the switch predischarge operation in a nitrogen laser circuit. The behavior of the breakdown voltage, when a trigger pulse is applied to the trigger electrode, is investigated, and the results are reported. Based on the experimental measurements ne...

Article presents results of study on possibility of increasing the efficiency of drilling directional straight sections of wells using screw downhole motors (SDM) with a combined method of drilling with rotation of drilling string (DS). Goal is to ensure steady-state operation of SDM with simultaneous rotation of DS by reducing the amplitude of oscillations with adjusting the parameters of dril...
