Study of the Dependence of Solar Radiation Regarding Design Variables in Photovoltaic Solar Installations with Optimal Dual-Axis Tracking
(MDPI, 2021)
Solar tracking is an efficient strategy to increase the radiative capture of photovoltaic collectors. Within the multiple efforts made in recent decades to improve the production of these facilities, various works have ...
A Pilot Study on the Feasibility of Developing and Implementing a Mobile App for the Acquisition of Clinical Knowledge and Competencies by Medical Students Transitioning from Preclinical to Clinical Years
(MDPI, 2022)
Due to the COVID-19 pandemic and the consequent restrictions, universities have had to adapt their curricula substantially to new schemes in which remote learning is of the essence. In this study, we assess the feasibility ...
Active, Reactive and Harmonic Control for Distributed Energy Micro-Storage Systems in Smart Communities Homes
(MDPI, 2017)
This paper aims to provide control strategies for distributed micro-storage energy systems at the residential level to contribute to smart grid goals. A simulation model of an energy storage system (ESS) charger has been ...
Low Range of Shoulders Horizontal Abduction Predisposes for Shoulder Pain in Competitive Young Swimmer
(Frontiers, 2019)
The prevalence of shoulder pain (SP) among competitive swimmers is high, and
may profoundly restrict their ability to compete. This prospective cohort study
investigated the association between 3 blocks of performance ...
LED street lighting: A power quality comparison among street light technologies
(SAGE Publications, 2012)
High-pressure sodium lamps are currently the main lamps used in public lighting.
However, the possibility of using high-power light emitting diode (LEDs) for street
lighting is growing continuously due to their greater ...
Novel Segmentation Technique for Measured Three-Phase Voltage Dips
(MDPI, 2015)
This paper focuses on issues arising from the need to automatically analyze
disturbances in the future (smart) grid. Accurate time allocation of events and the
sequences of events is an important part of such an analysis. ...
A Methodology for Automatic Identification of Units with Ecological Significance in Dehesa Ecosystems
(MDPI, 2022)
The dehesa is an anthropic complex ecosystem typical of some areas of Spain and Portugal, with a key role in soil and biodiversity conservation and in the search for a balance between production, conservation and ecosystem ...
Honey Bee Colonies Remote Monitoring System
(MDPI, 2017)
Bees are very important for terrestrial ecosystems and, above all, for the subsistence of many
crops, due to their ability to pollinate flowers. Currently, the honey bee populations are decreasing
due to colony collapse ...
Lightweight method of shuffling overlapped data-blocks for data integrity and security in WSNs
(Elsevier, 2021)
Wireless Sensor Networks (WSN) consist of devices with limited resources to explore and sense the environment in a cooperative way. Security, mainly in terms of guaranteeing the data integrity, is a primary issue for many ...
ZigBee Pulse Oximeter
(2011)
This work presents a prototype to adapt a standard
pulse oximeter by turning it into a wireless device using ZigBee.
Patient’s data are extracted and transmitted to the server in real
time through a Wireless Sensor ...
