Research ArticleOpen accessPhrase in the titleAnalytical Study on Fundamental Frequency Contours of Thai Tones using Tone-Geometrical ModelSuphattharachai ChomphanProblem statement: In tonal language speech; such as Thai, Mandarin and Vietnam, tone is an important feature of a syllable that must be taken into consideration, since tone is a supra-segmental feature in the speech prosody. Modeling of tone with high accuracy could enhance the quality of synthesized speech in the speech synthesis system. This study focuses on a model … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 7,100 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetermination of Flux linkage Characteristics and Inductance of a Submersible Switched Reluctance Motor using Software ToolsSundaram Maruthachalam, Navaneethan PalaniswamyProblem statement: The Switched Reluctance Motor (SRM) is an old member of the Electric Machines Family. It’s simple structure, ruggedness and inexpensive manufacturing capability make it more attractive for Industrial applications. Now, the applications of switched reluctance motors in various industrial fields are tried by many engineers. However, switched reluctance motors are not used so far in submersible underwater motor … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,658 accessesView PDFCite
Research ArticleOpen accessIn the abstractCFD Simulation of Biogas Fired Clay Brick KilnAlemayehu Beyene, Venkata Ramayya, Getachew ShunkiMore strong and quality clay bricks are obtained if and only if bricks are fired with uniform optimum temperature during clay brick firing process in the clay brick kiln. To insure this transient temperature of fluegas and brick are analyzed using CFD simulation during clay brick firing in the clay brick kiln. In the simulation, 3-D geometrical model of fluegas … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 20 Jun 2018 · 8,799 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress 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 abstractHoneycomb Sandwich Specimens Made of PLA and Produced Via 3D FDM Printing Process: An Experimental StudySalvatore Brischetto, Roberto TorreIn recent years, the 3D Fused Deposition Modelling (FDM) technology, usually employed for the production of nonstructural objects, has been also used by the present authors for the production of small structural elements where the applied loads are moderate. A typical application could be the production of small Unmanned Aerial Vehicles (UAVs) where stresses are not excessive. In these cases, … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 25 May 2020 · 11,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Unified Approach for the Shear Buckling Design of Structural Glass Walls with Non-Ideal RestraintsChiara Bedon, Claudio AmadioIn this study, a unified design approach is assessed and proposed for the shear buckling verification of structural glass walls supported by non-ideal restraints. Based on the current trends of practice in buildings, the effect of (i) adhesive joints, (ii) metal frames with interposed adhesive joints or (iii) point mechanical connectors on the actual shear buckling behavior of the examined … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 22 Jan 2016 · 8,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical System of Flat ElectroencephalographyTan Lit Ken, Tahir bin Ahmad, Mohd Sham bin Mohamad, Su Kong NgienFlat EEG is a way of viewing electroencephalography signals on the real plane. The wealth of information contained within makes it a great platform to study epileptic seizure. In this study, the time embedment nature of Flat EEG is exploited to establish a dynamic Flat EEG model. Basically, a geometrical representation which displays the important information visually for Flat EEG … …American Journal of Applied Sciences, Vol. 12, Issue 7 · 21 Aug 2015 · 6,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Physics: Emergent Unified Dynamical 3-Space, Quantum and Gravity: A ReviewReginald Thomas CahillExperiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec-1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the beginning of physics. This dynamical space generates a … …Physics International, Vol. 6, Issue 2 · 4 Aug 2015 · 8,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,654 accessesView PDFCite
