Numerical evaluation of the thermal performance of a near-surface earth-to-air heat exchanger with short-grass ground cover: A parametric study
(
Elsevier
, 2021 , Article)
High energy consumption and increasing energy cost have encouraged investment in energy efficiency. In hot areas, like the Middle East, the share of space cooling accounts for most of the total energy use in buildings. ...
Evaluation of different personalized ventilation air terminal devices: Inhalation vs. clothing-mediated exposures
(
Elsevier
, 2021 , Article)
Human exposure to particles indoors occurs through direct inhalation or indirectly through deposition on clothes that release them in other spaces. Ventilation systems are installed to decrease direct exposure but little ...
Global evaluation of WBGT and SET indices for outdoor environments using thermal imaging and artificial neural networks
(
Elsevier
, 2020 , Article)
The health and well-being of occupants of outdoor environments are largely affected by thermal stress, and therefore a global assessment is essential. Wet-bulb globe-temperature (WBGT) is used as a heat stress indicator ...
A novel robust automated FFT-based segmentation and features selection algorithm for acoustic emission condition based monitoring systems
(
Elsevier
, 2015 , Article)
This paper aims at developing a robust, fast-response and automated FFT-based features selection algorithm for the development of acoustic emission practical condition based monitoring applications of mechanical systems. ...
Effect of individually controlled personalized ventilation on cross-contamination due to respiratory activities
(
Elsevier
, 2021 , Article)
While personalized ventilation (PV) has been integrated to enhance inhaled air quality, some studies showed that it can contribute to contaminants' transport indoors. This work investigates the effect of the individual ...
Regression models for performance prediction of counter flow dew point evaporative cooling systems
(
Elsevier Ltd
, 2019 , Article)
Practitioners take more interest in the output conditions of cooling systems than the details of the processes. In this study, regression models are developed that relate input parameters, including operational and geometrical ...
The effect of forced convection and PCM on helmets' thermal performance in hot and arid environments
(
Elsevier Ltd
, 2017 , Article)
Safety helmets are essential Personal Protecting Equipment (PPE) in all industrial and construction sites. When temperature and humidity levels are high, users' thermal comfort is adversely affected. This paper examines ...
Characterisation of major fault detection features and techniques for the condition-based monitoring of high-speed centrifugal blowers
(
International Institute of Acoustics and Vibrations
, 2016 , Conference Paper)
This paper investigates and characterises the major fault detection signal features and techniques for the diagnostics of rotating element bearings and air leakage faults in high-speed centrifugal blowers. The investigation ...
An Intelligent Hybrid Experimental-Based Deep Learning Algorithm for Tomato-Sorting Controllers
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Conventionally, the methods used for the sorting of tomatoes are manual. These methods are costly, non-productive, and their reliability is uncertain. With advancing technology, deep-learning, and artificial intelligence ...
Design challenges of agricultural greenhouses in hot and arid environments - A review
(
Elsevier B.V.
, 2019 , Article Review)
Protected Agriculture (PA) presents a sustainable solution for food production in hot and arid environments. Harsh climate and the water deficit are obstacles to all year round cultivation. The greenhouse design should ...
