Research ArticleOpen accessEvery word in the titleJoint Modelling of Longitudinal-Time-To-Event with Categorical Variable Indicators of Latent Classes: Application to Tuberculosis DataAdeboye Azeez, Mutambayi Ruffin, Ndege James, Qin YongsongIn many clinical and reliability research reports, the outcomes of basic interest is the time to a particular event happens in order to indicate the person’s “true” state of health or survival status. Different models have been used to analyze such data separately, but may be unsuitable if the longitudinal and health status measures are correlated. In this study, mixed … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 9 Jun 2020 · 6,686 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleBiofidel FEA Modeling of Customized Hybrid Biological Hip Joint Design Part II: Flexible Stem Trabecular ProsthesesRaffaella Aversa, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Antonio ApicellaNew biomechanical criteria for the design of biomimetic hip joint prostheses are presented. Biofidel Finite Element Models have been used both to correctly analyze femur physiological and structural behavior and to assess a new design criterion for the development of innovative hybrid biological hip prostheses. Proper identification of isostatic lines and isorigidity regions for the sintered metal trabecular lattices distribution … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 16 Dec 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiofidel 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
Research ArticleOpen accessEvery word in the titleA Survey on Joint Compression and Encryption Techniques for Video DataK. John Singh, R. ManimegalaiProblem statement: When we send any video data over the network it consumes more time. This is due to the huge size of the video file when compared to text file. Therefore, video data should be compressed before sending to the destination. Another important factor during data transfer is security. Joint compression and encryption is employed to enable faster and … …Journal of Computer Science, Vol. 8, Issue 5 · 28 Feb 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Losses and Flux Distribution in 3 Phase 100 kVA Distribution Transformers Assembled from Various Type of T-Joint GeometryI. Daut, Dina M.M. Ahmad, S. Zakaria et al.This paper describes results of an investigation of the variation of power loss, building factor, flux leakage and flux distribution in 3-phase model transformer cores assembled from various type of T-joint geometry. The loss of the core with T-joint 60o was 10%, 12% and 15% better than the core with T-joint 45o, T-joint 23o and T-joint 90o respectively and 1.7 … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 31 Dec 2009 · 6,893 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTwo Main Methods for Utility Sharing in Joint Business: A DiscussionRafel Amer, Francesc Carreras, Antonio MagañaOne of the main purposes of any theory of joint business is to provide a convincing way for sharing the total utility available to the set of agents. The proportional rule is widely applied in practice but people using this method should be warned that it is not as innocent, effective, fair and consistent as it seems at first glance. … …Journal of Mathematics and Statistics, Vol. 3, Issue 1 · 31 Mar 2007 · 6,894 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria.
