Direct-current (DC) microgrids have gained worldwide attention in recent decades due to their high system efficiency and simple control. In a self-sufficient energy system, voltage control is an important key dealing with upcoming challenges of renewable integration into DC microgrids, thus storage systems (ESSs) are often employed suppress the power fluctuation ensure stability. this paper, pe...

(1) Background: This study examines school bullying and cyberbullying, which are unfortunate realities in our schools that require interdisciplinary, multidimensional educational interventions order to enhance the quality of process. (2) Methods: The analyzes results application School Harassment Questionnaire (CAES) 494 students sixth year primary school, aged between 11 13, Spanish region Cas...

Debemos reflexionar sobre lo que ha ocurrido durante el confinamiento, tener en cuenta las voces protagonistas de nuestro estudiantado para mejorar a partir la visibilización no funcionado. Este artículo recoge 20 estudiantes empiezan sus prácticas formación inicial maestro-a presenciales y, del pasan realizarlas manera virtual. De este total 10 estaban tercer curso y cuarto curso. Los centros ...

The oblique flow compressor is one of the important components in compressed air energy storage (CAES) system. structural shape radial inlet chamber (RIC) directly affects performance, and a reasonable RIC design should achieve smallest total pressure loss outlet distortion as much possible to meet design. To study influence splitter blades, 4 RICs equipped with different numbers blades are des...

Responses from a large sample of 1,029 chief audit executives (CAEs) from Australia, Canada, New Zealand, the U.K./Ireland, and the U.S. are used to estimate the proportion of time spent by internal audit functions (IAF) on information technology (IT) audits. The sample is also used to investigate explanatory and control variables that are associated with the extent of IT audits by IAFs. The re...

This paper provides an approach for recognizing human activities with wearable sensors. The continuous autoencoder (CAE) as a novel stochastic neural network model is proposed which improves the ability of model continuous data. CAE adds Gaussian random units into the improved sigmoid activation function to extract the features of nonlinear data. In order to shorten the training time, we propos...

In this paper, the topic of Compressed Air Energy Storage (CAES) is discussed and a program in which it is being applied to a wind turbine system for leveling power supplied to the grid is described. Noted is the importance of heat transfer in the design of the compressor and its effect on performance. Presented is a design for minimizing the temperature rise in the compressor during compressio...

This paper is based on the improvement of power quality (PQ) using fuel cell and fuzzy controller. By proposed controller, in grid system especially micro connected with non- linear unbalanced load enhanced. The configuration combined hybrid arrangement photovoltaic ([PV) wind energy conversion (WECS), (FC) including compressed air storage (CAES) where management controlled by distributed shari...
