Research ArticleOpen accessEvery word in the titleExplainable MedAttn-ResNet50 for Automated Kidney Tumor Classification from CT Images With Grad-CAM VisualizationD. Vetrithangam, Pramod Kumar, Shilpasree S. et al.Kidney tumor classification from CT imaging remains challenging due to CT-specific intensity variations, tumor heterogeneity, and limited clinically meaningful interpretability in existing deep learning models. To address these limitations, we propose an Explainable MedAttn-ResNet50 framework that integrates radiology-driven preprocessing, multi-scale feature extraction, and medical attention mechanisms within a unified architecture. The preprocessing pipeline applies radiology-inspired intensity normalization, contrast enhancement, and … …Journal of Computer Science, Vol. 22, Issue 8 · 13 Aug 2026 · 1,120 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicroleakage Assessment of CAD/CAM Endo Crown Restorations (an in vitro Study)Mohamed Ahmed Wakwak, Karim Sherif Adly, Abdallah Ahmed Abdelhady, Ahmed Ramdan ElmanakhlyThe preservation of tooth structure is an important factor in the successful restoration of endodontically treated teeth. The loss of structural integrity increases the occurrence of crown fractures and microleakage at the margins of restorations in endodontically treated teeth compared with vital teeth. A total of twenty endocrowns were fabricated in this study and the endocrown was divided into two … …Current Research in Dentistry, Vol. 14, Issue 1 · 13 Apr 2023 · 6,179 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Multi-Criteria Optimization Approach to Cam Curve Design Combining Different Splines Given by Fixed and Adjustable CheckpointsLéo Moussafir, Vigen ArakelianThis study proposes a multi-criteria design optimization of cam mechanisms. This approach is based on the multistage interconnection of different tools: MATLAB, ADAMS, and mode frontier. It consists of three main issues: (i) The polynomial representation of splines given by checkpoints defining the specific motion of the follower; (ii) The connection of these splines by different degrees of fitting in … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 24 Mar 2023 · 6,646 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCam-Gears Forces, Velocities, Powers and EfficiencyRaffaella Aversa, Relly Victoria V. Petrescu, Bilal Akash et al.The paper presents a method of the original type in order to determine the effectiveness of a mechanism camshaft and adept. The originality of this method consists of eliminating the friction. In this research analyzes the four types of side camshaft: 1. Camshaft rotary switch and the motherboard translated adept; 2. The mechanism with the camshaft rotary switch and openness … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 May 2017 · 8,622 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMorphing Mechanisms Part 1: Using Iterative Learning Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis study introduces the concept of morphing mechanisms. Mechanisms are normally designed for specific operating conditions and once they are built one may wish to use them under different operating conditions. In some cases, a mechanism may be imperfectly fabricated and one would like to get the intended ideal performance. In these cases, instead of designing, fabricating and replacing the … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,837 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigating Campylobacter Spp. in Mekong Delta Duck Farms: Prevalence, Risk Factors, and Antibiotic ResistanceNguyen Vu Thuy Hong Loan, Le Trung Kien, Do Ngoc Yen Phuong et al.Campylobacter spp. is a leading cause of gastroenteritis worldwide, contributing to significant health and economic burdens, especially in poor hygiene practices. Investigating this bacterium's prevalence and antibiotic resistance in ducks from the Mekong Delta is essential, as the region's extensive duck farming industry presents a potential risk for transmission to humans through the food chain. During August 2024 to February … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 8 Feb 2026 · 1,615 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Altitude on Species Diversity and Vegetation Structure of Kigelia africana Parklands in CameroonAwé Djongmo Victor, Vroh Bi Tra Aimé, Noiha Noumi Valery et al.In the Faro Subdivision (North, Cameroon), there are populations of Kigelia africana, known by the common name “Dambale", whose variety is largely unknown. The study's goal is to demonstrate how altitude affects species diversity and vegetation structure in Kigelia africana parklands. To gather information for statistical analysis, a Randomized Complete Block Design (RCBD) was employed. A total of 90 quadrats … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 20 Dec 2025 · 3,176 accessesView PDFCite
