Computational characterization of the behavior of a saliva droplet in a social environment
(Nature Research, 2022-04)
[EN] The conduct of respiratory droplets is the basis of the study to reduce the spread of a virus in society. The pandemic suffered in early 2020 due to COVID-19 shows the lack of research on the evaporation and fate of ...
Natural Ventilation Characterization in a Classroom under Different Scenarios
(MDPI, 2021-05-19)
The COVID-19 pandemic has pointed to the need to increase our knowledge in fields related to human breathing. In the present study, temperature, relative humidity, carbon dioxide (CO2) concentration, and median particle ...
Forecast Error Sensitivity Analysis for Bidding in Electricity Markets with a Hybrid Renewable Plant Using a Battery Energy Storage System
(MDPI, 2020-04-28)
Deep integration of renewable energies into the electricity grid is restricted by the problems related to their intermittent and uncertain nature. These problems affect both system operators and renewable power plant owners ...
Modeling of Motorized Orthosis Control
(MDPI, 2019-06-15)
Orthotic devices are defined as externally applied devices that are used to modify the structural and functional characteristics of the neuro-muscular and skeletal systems. The aim of the current study is to improve the ...
Numerical Modeling of the Spread of Cough Saliva Droplets in a Calm Confined Space
(MDPI, 2021-03-08)
The coronavirus disease 2019 (COVID-19) outbreak has altered the lives of everyone on a global scale due to its high transmission rate. In the current work, the droplet dispersion and evaporation originated by a cough at ...
Testing the Accuracy of the Cell-Set Model Applied on Vane-Type Sub-Boundary Layer Vortex Generators
(MDPI, 2021-03-11)
Vortex Generators (VGs) are applied before the expected region of separation of the boundary layer in order to delay or remove the flow separation. Although their height is usually similar to that of the boundary layer, ...
A New Loss Function for Simultaneous Object Localization and Classification
(MDPI, 2023-03-01)
Robots play a pivotal role in the manufacturing industry. This has led to the development of computer vision. Since AlexNet won ILSVRC, convolutional neural networks (CNNs) have achieved state-of-the-art status in this ...
A Study of Learning Issues in Feedforward Neural Networks
(MDPI, 2022-09-05)
When training a feedforward stochastic gradient descendent trained neural network, there is a possibility of not learning a batch of patterns correctly that causes the network to fail in the predictions in the areas adjacent ...
Numerical modeling of a sneeze, a cough and a continuum speech inside a hospital lift
(Elsevier, 2023-02)
The global COVID-19 and its variants put us on notice of the importance of studying the spread of respiratory diseases. The most common means of propagation was the emission of droplets due to different respiration activities. ...
Stability Analysis for Autonomous Vehicle Navigation Trained over Deep Deterministic Policy Gradient
(MDPI, 2022-12-27)
The Deep Deterministic Policy Gradient (DDPG) algorithm is a reinforcement learning algorithm that combines Q-learning with a policy. Nevertheless, this algorithm generates failures that are not well understood. Rather ...
