Research ArticleOpen accessEvery word in the titleAn Occlusion Aware Facial Expression Recognition Model Using Fitness Based Cheetah Optimizer and Adaptive Multi-Scale ViT-CNN With Attention MechanismA. Reddy Prasad, A. RajeshAs a highly nuanced aspect of human communication, facial expression recognition presents a computationally complex problem, making it a prominent area of research in computer vision and affective computing. Problems like poor image quality, occlusions, inconsistent illumination, and head attitude changes are frequently observed in images taken from unstructured sources such as the internet that affect the accuracy of facial … …Journal of Computer Science, Vol. 21, Issue 12 · 29 Jan 2026 · 1,962 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSM-SCAM YOLO: Enhancing Object Detection with Multi-Scale Module and Spatial Channel Attention MechanismShanmuga Sundari Mariyappan, Kayalvizhi Mohan, K. B. K. S. DurgaDetecting tiny objects remains a significant hurdle in computer vision, primarily due to scale variation, occlusion, and the loss of detail in low-resolution features. Although YOLO-based detectors are popular for their speed and efficiency in real-time tasks, they often struggle with accurately identifying small objects because of information loss during downsampling. This study introduces an improved YOLO-based model that integrates … …Journal of Computer Science, Vol. 21, Issue 6 · 12 Jun 2025 · 3,921 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Combined Deep Learning Model with Attention Mechanism for Detection of Implant Manufacturer Using X-Ray ImagesAttar Mahay Sheetal, K. SreekumarShoulder replacement surgery is one of the invasive techniques in orthopedic disciplines that replaces dead shoulder joints with prostheses made from polyethylene and metal components. To perform the surgery, there is a need to know the implant accessories and manufacturer of the implant. Some problems arise in a situation where the patient experiences pain and shoulder malfunctions that need replacement, … …Journal of Computer Science, Vol. 21, Issue 6 · 12 Jun 2025 · 3,252 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDehazing Mechanism Using Auto-Encoder with Intensity Attention SystemRajat Tiwari, Bhawna Goyal, Ayush DograIn the modern world, images play a significant medium for communication. Primarily, it is easily transferred and disseminated across various platforms which allows the people to express their ideology and perceptions. Conversely, images can be prone the environmental conditions as the image quality can be affected by the weather circumstances. Particularly, haze images minimize the whole clarity and visibility of … …Journal of Computer Science, Vol. 20, Issue 12 · 25 Nov 2024 · 4,513 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification Model of Traditional Chinese Medicine Prescription Decocting Duration Combining Text Convolutional Neural Network with Attention MechanismZhibiao Li et al.The decocting time of Traditional Chinese Medicine (TCM) formulas is crucial for therapeutic effects. To better capture the important characteristics related to the decocting time of TCM formulas, a formula decocting time classification model TextCNN-attention that integrates the attention mechanism and Text Convolutional Neural Network is proposed. This model predicts the decocting time of formulas and divides them into long-term, … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 26 Sep 2024 · 4,366 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProsthetic Knee Mechanism Using a Double Locking System as a Safety MeasureEicarl Saynes Vazquez, Esther Lugo GonzálezThe design of a four-link knee prosthesis mechanism with two locking systems activated during the flexion/extension phase is presented. The first is geometric, totally mechanical and activated by the user's weight. The second is variable and is activated automatically when walking on irregular or special surfaces is required. The links' dimensions were selected using the differential evolutionary optimization algorithm to … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 12 Feb 2024 · 5,701 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Learning Mechanism to Improve Skills Acquisition for Autistic Children in MauritaniaCheikhne Mohamed Mahmoud Seyidi, Cheikhane Seyed, Mohamed El Moustapha El Arby et al.The learning of autistic children is an issue for care and treatment centers for children with autism spectrum disorder, however many studies seek to find learning mechanisms and models in order to facilitate their social integration. The aim of this study is to propose a learning mechanism based on the analysis and annotation of a corpus video filmed during the … …Journal of Computer Science, Vol. 19, Issue 9 · 23 Aug 2023 · 5,618 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Bridging and Deflection Toughening Mechanisms of Staggered Hydroxyapatite Lamellar Microstructure in BoneYuxi Liu, Xiaohui He, Shuge Li, Zhangdong SunThe observation experiment results of the microstructure of tibial cortical bone show that the cortical bone is a layered bio-ceramic composite material composed of Hydroxyapatite (HAP) and collagen arranged alternately. HAP is a reinforcing phase and accounts for a large proportion in cortical bone. These hydroxyapatites have long and thin sheet-like structures parallel to the outer surface of the bone, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 890 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeometric-Cinematic Synthesis of Planetary MechanismsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe simple planetary mechanism is geometrically synthesized by determining the four tooth numbers of the component wheels. There are four main conditions that if not obeyed the mechanism will be blocked, will work with interruptions, or will not work at all. (a) The first condition in the geometric-kinematic synthesis of a simple planetary is the uniform loading of satellites (satellite … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 28 Aug 2018 · 7,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of an Oscillating Sliding MechanismFlorian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaA mechanism with an oscillating slider is a mechanism quite often used in the technique. It has some advantages over other similar mechanisms being able to work with accelerations and reduced forces under the same conditions with another similar mechanism. For example, an internal combustion engine could be built more efficiently with this mechanism, resulting in a motor that would … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,005 accessesView PDFCite
