Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Anthropomorphic Gripping Manipulator: The Study of Kinematics and Virtual Modeling of GripIvan Vladimirovich Krechetov, Arkady Alekseevich Skvortsov, Pavel Sergeevich Lavrikov, Danil Vladilenovich YatskinThe article is a study into the kinematic scheme of a newly developed anthropomorphic manipulator designed to perform gripping and holding tasks on items from a predefined set. Within the study is the implementation of a mathematical model describing the kinematics of a multilink manipulator using the GraspIt package. The method used in this study allows for the calculation of … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 8 Jan 2016 · 7,682 accessesView PDFCite

Research ArticleOpen accessIn the abstractExtraction of Arabic Standard MicromelodyA. Chentir, M. Guerti, D. J. HirstProblem statement: In the early days of speech synthesis research the obvious focus of attention was intelligibility. But many researchers agree that the major remaining obstacle to fully acceptable synthetic speech is that it continues to be insufficiently natural. Approach: In this study, we exploited microvariations of fundamental frequency (F0) of speech (intrinsic and co-intrinsic effects) to extract micromelody effect … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,291 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHybrid Deep Learning Models for Text Classification: Performance Evaluation of TriDistilBERT and BiGRU ArchitecturesAmira Samy TalaatText can be a valuable source of information, but its unstructured nature makes analysis challenging and time-consuming. Machine Learning (ML) algorithms can efficiently analyze and structure text, enabling organizations to automate processes and uncover insights that support better decision-making. This study focuses on applying ML to a classification problem using two datasets. Four deep learning models are introduced, combining Bi … …Journal of Computer Science, Vol. 21, Issue 9 · 10 Oct 2025 · 2,799 accessesView PDFCite
