Research ArticleOpen accessIn the keywordsAnalysis of Indoor CO2 Concentration Using Split Ventilation Systems as an Indicator of COVID-19 TransmissionManuel Batista, Oscar Bulgim, Ericka Matus et al.We measured the indoor CO2 concentration in occupied areas with ventilation systems that recirculate air without an external air supply. The average time required to achieve the highest probability of contagion was also measured based on the number of participants in the group. Three different experimental groups were evaluated: Group One (G1), which included 5 participants; Group Two (G2), with … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 23 Aug 2023 · 6,051 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Convolutional Neural Network Approach for Skin Lesion Classification Using Imbalanced Dataset with Image AugmentationZhyar Yassin Abdalla, Nor Hazlyna Harun, Mohammed Shihab AhmedA significant threat to people's health all over the world is skin cancer. The purpose of this research is to improve the detection of skin cancer by utilizing a CNN classification model that makes use of preprocessing and augmentation techniques. The HAM10000 dataset is used, and the imbalance it contains is addressed by resizing the images to 120×120 pixels and … …Journal of Computer Science, Vol. 20, Issue 11 · 10 Sep 2024 · 5,427 accessesView PDF Cite
