Research ArticleOpen accessEvery word in the titleNew Model-Based Fault Detection Approach using Black Box ObserverM. Abdullah Eissa, R. R. Darwish, A. M. BassiunyMost of the emerging engineering systems lack the presence of explicit physical insights or prior knowledge that clearly depicts the model. In such cases, the conventional observer-based fault detection is difficult to be employed because of its observer gain tuning. Herein, black box behaviors arose as a promising trend that could overcome those challenges that appears due to lacking the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 15 Mar 2019 · 6,613 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSliding Mode Observer-Based Fault Reconstruction for Uncertain Linear SystemsSlim Dhahri, Faycal Ben Hmida, Anis SellamiProblem statement: Fault reconstruction scheme is different from the majority of Fault Detection and Isolation (FDI) methods described in the literature in the sense that it not only detects and isolates the fault, but provides an estimate of the fault. This approach is very useful for incipient faults and slow drifts, which are very difficult to detect. Also, this approach … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 8 Sep 2011 · 7,350 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInduction Motor Flux Estimation using Nonlinear Sliding ObserversHakiki Khalid, Mazari Benyounès, Djaber Sid’AhmedA nonlinear sliding flux was proposed for an induction motor. Its dynamic observation errors converge asymptotically to zero, independently from the inputs. The aim of this work was to study the robustness of this observer with respect to the variation of the rotor resistance known to be a crucial parameter for the control. The dynamic performance of this sliding observer … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 6,794 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFault Reconstruction Using Sliding Mode ObserversK. Hakiki, B. Mazari, A. Liazid, S. DjaberIn this study, a nonlinear sliding observer is proposed to explicitly reconstruct fault signals. The novelty lies in the application of the equivalent output injection concept. Previous work in the area of fault detection has used disruption of the sliding motion to detect faults. The aim of the present study was to design a robust observer that slides in the … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,680 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Positioning of Laser Beams Using Proportional Integral Derivative and Based Observer-Feedback ControlKwabena A. Konadu, Sun Yi, Wonchang Choi, Taher Abu-LebdehHigh-precision positioning of laser beams has been a great challenge in industry due to inevitable existence of noise and disturbance. The work presented in this study addresses this problem by employing two different control strategies: Proportional Integral Derivative (PID) control and state feedback control with an observer. The control strategies are intended to stabilize the position of a laser beam … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 19 Apr 2013 · 6,868 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,904 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling of Observer-Based Social Media Marketing for Saudi Arabia ConsumersMahmoud Alblowi, Omar Aloufi, Najmah Fallatah et al.Global change has been significantly amplified by the Internet's swift development of technology. The emergence of social media has marked a significant improvement in communication and information availability. Therefore, the social media marketing industry is a significant area used to advertise a wide range of products. In the Kingdom of Saudi Arabia (KSA), social media platforms have been widely used … …Journal of Computer Science, Vol. 19, Issue 7 · 11 Jun 2023 · 5,814 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimising Pair Programming in a Scholastic Framework: A Design Pattern PerspectiveSmitha Rajagopal, Katiganere Siddaramappa Hareesha, Poornima Panduranga KundapurPair programming is one of the widely used practices of Extreme Programming (XP). XP is a software development process which intends to enhance quality of software code in order to cater to the ever increasing demands of customers looking for IT solutions. Pair programming promotes team building, raises confidence among individuals and eventually results in richer and a better codebase. … …Journal of Computer Science, Vol. 13, Issue 6 · 20 May 2017 · 7,250 accessesView PDFCite
Research ArticleOpen accessIn the abstractIoT-Integrated CNN Deep Learning for Automated Breast Cancer Detection and DiagnosisYamini Kalva, R. Ganesh Babu, Sindhu V. et al.Breast cancer continues to be a primary cause of death in women, requiring prompt and accurate diagnosis to enhance treatment results. Traditional diagnostic techniques depend on manual assessment, which leads to possible misclassification, significant inter-observer variability, and delays in decision-making. Current deep learning models, including CNNs, frequently experience feature loss, gradient declining and restricted adaptability to real-time data. To overcome … …Journal of Computer Science, Vol. 22, Issue 4 · 30 Mar 2026 · 1,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptiCNN: Local thresholding segmentation and CNN with SVM Approach for Diabetic Retinopathy Detection and Classification of Fundus ImagesAnju Mishra, Mrinal Pandey, Laxman SinghDiabetic Retinopathy (DR) is a progressive eye disease that can lead to vision loss and blindness if left untreated. Ophthalmologists diagnose DR using medical imaging modalities such as fundus photography and optical coherence tomography (OCT); however, manual interpretation of these images is time-consuming and subject to inter-observer variability. While DR is irreversible, vision loss can be prevented through early detection … …Journal of Computer Science, Vol. 21, Issue 10 · 15 Dec 2025 · 2,153 accessesView PDFCite
