Caring for older adults with disabilities is a source of stress family caregivers, and the lack social support pressure exclusion might aggravate caregiver burden. This study aimed to examine association between caring load caregivers' burden, as well mediating effects exclusion.Data used in this was derived from nationally representative database aged population China, 3,125 households disabled old their home-bound caregivers were eventually selected analysis. Regression methods mediation...

Abstract A stall diagnosis method based on the entropy feature extraction algorithm is developed in axial compressors. The reliability of proposed determined and a parametric sensitivity analysis experimentally conducted for two different types compressor diagnoses. collection time‐resolved pressure sensors mounted circumferentially along chord direction to measure dynamic casing. Results show that prestall precursor embedded pressures are identified through nonlinear perturbation using...

The DC transformer based on the Modular Multilevel Converter (MMC) structure has advantages of robust scalability, low output voltage harmonic content, easy realization back-to-back connection, and high power transmission efficiency. It is widely used in distribution networks. However, traditional control methods hardly provide inertia for network, thereby reducing stability network when new energy fluctuations, failures, or other disturbances occur. Aiming at problem that bus easily...

Nonintrusive load identification is an important aspect of monitoring and can be accomplished using sensor data. In this article, we propose multichannel imaging-based methods with REW (MCIR)-convolutional neural network (CNN), a novel method that leverages imaging time-series data CNNs. We introduce new based on Rényi entropy for determining the sliding window size when segmenting time series into subsequences, which refer to as (REW). Our relies accurately classify loads, providing...

The vibration of the robot during movement brings various irregular motion disturbances to robot's head, these results into unstable images captures by head-mounted vision system and therefor cannot accurately perceive environment. This paper presents a mechanical stabilization method based on gravity disturbance compensations, which considers compensates influences structure external disturbances. Finally, current command joint motor is generated can quickly stabilize image. We performed...

Abstract Background Cervical cancer cell detection is an essential means of cervical screening. However, in thin-prep cytology test-based images, the accuracy traditional computer-aided algorithms typically low due to overlap cells with blurred cytoplasmic boundaries. Clinical applications face more difficulties. Method we propose a network (3cDe-Net) based on improved backbone and multiscale feature fusion, consists head. In network, dilated convolution group are introduced improve...

An accurate and efficient method to predict the shielding effectiveness (SE) of a rectangular enclosure with apertures is presented. A more mathematical disposal suggested for calculation slot impedance. And point replace former approximate expression by rigorous elliptical integration. Finally, predicted results new are compared measured data good agreement reported.

In order to make the performance of externally gapped line arrester (EGLA) meet requirements national standards better, discharge voltage its gap becomes most important parameter so that study on relationship between and other factors is considered as a critical project. Generally, before discharging, distribution unit mainly affected by equivalent capacitance. As result, there close relevance capacitance well this paper, capacitances gaps in different structures with parameters were...

Based on the relationship between proper distance and coordinate distance, geometrical phenomenon caused by passing gravitational waves can not be observed locally. The electromagnetic wave equations in background are studied. We find that expansion contraction of lengths always synchronous with objects it measures. leads to dissipation dispersion propagation wave. phase control term telegrapher's equation. linearly polarized laser beam propagating direction incoming give a possible...

Abstract Objective: Caring for the disabled elderly is a source of stress family caregivers, and lack social support pressure exclusion might aggravate caregiver burden. The purpose this study was to examine association between caring load caregivers’ burden, as well mediating effects exclusion. Methods: Data used in derived from nationally representative database aged population China, 3125 households with caregivers home-bound were eventually selected into analysis. Regression methods...
