Effective fault detection and classification play essential roles in reducing the hazards such as electric shocks and fire in photovoltaic (PV) systems.However, the issues of interest in fault detection and classification for PV systems remain an open-ended challenge due to manual and time-consuming processes that require the relevant domain knowle
Snacks To reduce the negative impacts of stall and surge on compressor performance, a novel combined casing treatment (CCT) structure with axial skewed slots and injection groove is proposed in this paper.The aerodynamic performance, as well as the mechanisms of loss generation, of a transonic axial compressor with NASA Rotor 67 are investigated nu
Qualitative Longitudinal Research (QLR) is a dynamic and evolving methodology using time as a lens to inform study design, data collection and analysis.A key feature of QLR is the collection of data on more than one occasion, often described as waves or time points.Thus, researchers embarking on designing a new study need to consider several key fe
A blast injury is a complex type of physical trauma resulting from the detonation of explosive compounds and has become an important issue due to the use of improvised explosive devices (IED) in current military conflicts.Blast induced neurotrauma (BINT) is a major concern in contemporary military medicine and includes a variety of Snacks injuries
In order Snacks to solve the problem of limited driving speed of piezoelectric actuators when the piezoelectric components are small and the driving frequency is low.This paper proposes a bi-directional piezoelectric stick-slip actuator, which mainly utilizes the combination of flexible drive foot and lever amplification mechanism to realize the di
