Research ArticleOpen accessEvery word in the titleGeometric Optimization of Three-Phalanx Prosthesis Underactuated Fingers using Particles Swarm AlgorithmSomar M. Nacy, Shaker S. Hassan, Sadeq Hussein BakhyProblem statement: One are now interested to investigate the optimum design procedure for a finger driving mechanism to have a good configuration of the finger for its utilization in hand prosthesis. A Geometric Optimization of Three-Phalanx Prosthesis Underactuated Fingers (TPPUF) based on a Particle Swarm Optimization (PSO) was presented. Approach: Firstly, a numerical evaluation of the human-like motion was obtained … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,701 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Speech Processing Strategies in Cochlear ImplantsKouachi Rouiha, Djedou Bachir, Bouchaala AliCochlear implants can restore partial hearing to profoundly deaf people; the main function of these prostheses is to electrically stimulate the auditory nerve using an electrode array inserted in the cochlea. The acoustic signal is picked up by a microphone and analyzed. Then the extracted parameters of the signal are coded to generate electrical signals reconstituting the original signal. Currently … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,839 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStress Analysis of an Artificial Human Elbow Joint: Application of Finite Element AnalysisStephen K. ArmahThe elbow joint is frequently affected by two kinds of arthritis (degenerative arthritis and rheumatoid arthritis) following some kind of injuries. There have been efforts since the eighteenth century by various individuals and organizations in modeling permanent implants for the elbow joint, but some of the prostheses have been disappointing because of lack of understanding of the biomechanics of the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 4 Jan 2018 · 9,533 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDevelopment of an Anthropomorphic Gripping Manipulator: The Analysis of Implementation MethodsIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich LavrikovThe object of the article is the study of implementation methods for the development of hardware-software engineering solutions in the field of the creation of a universal anthropomorphic gripper. Such technical solutions are intended to enable the adaptation and extensive use of advanced robotic systems in the natural environmental conditions formed by people through equipping them with anthropomorphic universal grippers … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPersonal Computer Based Clinical Programming Software for Auditory ProsthesesK. Rajakumar, P. Seetha RamaiahAuditory Prostheses (AP) are widely used electronic devices for patients suffering with severe to profound senosorineural deafness by electrically stimulating the auditory nerve using an electrode array surgically placed in the inner ear. AP mainly contains external Body Worn Speech Processor (BWSP) and internal Implantable Receiver Stimulator (IRS). BWSP receives an external sound or speech and generates encoded speech data … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 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
Case ReportOpen accessIn the abstractHistopathology of Microbially Induced Corrosion and Cluster Failure of Moderately Rough Surface Oral Implants in a Resident Bone MicrobiotaStephen Nelson, Helen Hu et al.This case report presents as a maxillary "cluster-failure", where six moderately rough-surface oral implants (1-2 microns) were installed to support a full-arch hybrid bridge. Understanding cluster failures requires the acknowledgment of biofilm science that recognizes the persistence of bacterial infection in bone following extraction and the need to bioremediate the bone-bed, by surgical debridement, before implant installation. The patient, a … …Current Research in Dentistry, Vol. 15, Issue 1 · 28 Feb 2024 · 8,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractProsthetic 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
Review ArticleOpen accessIn the abstractNews in Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentRelly Victoria Virgil Petrescu, Raffaella Aversa, Valeria Perrotta et al.The complex biomechanics and morphologies of the femur proximal epiphysis are presented. The nature and fine morphology of the femur head and its structural behavior have been investigated. Isotropic and orthotropic trabecular structures have been associated with oriented compression and tensioned areas of the femur head FEM models. These isotropic/orthotropic trabecular morphologies and their allocations govern the stress and strain … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 14 Jun 2021 · 6,351 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofidel FEA Modeling of Customized Hybrid Biological Hip Joint Prostheses, Part I: Biomechanical Behavior of Implanted FemurRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaBiofidel femur Finite Element Models have been developed using specific combination of Computer Tomography segmentation and solid modeling software tools able to represent bone physiology and structural behavior. These biofidel Finite Element Models (FEM) is used to evaluate the modification of the physiological stress distribution in a prosthesized femur and to assess new design criteria for the development of biomimetic … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 16 Dec 2016 · 8,716 accessesView PDFCite
