Research ArticleOpen accessEvery word in the titleFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComputer Model For Sieves' Vibrations Analysis, Using an Algorithm Based on the False-Position MethodDinu I. Stoicovici, Miorita Ungureanu, Nicu Ungureanu, Mihai BanicaThe analysis of the sieves vibrations in the case of screening civil engineering construction bulk materials is usual made by using some differential equations depending on parameters related to different material and sieves characteristics. One of those parameters is the throwing coefficient -c- that is the ratio between the force capable to throw up the particle from the sieve surface, … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,780 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReal-Time Fuzzy Logic Control of Two-Link Flexible ManipulatorsJimoh Olarewaju Pedro, Juan-Paul HynekThis study investigates the development of a Fuzzy Logic Controller (FLC) for tracking a sinusoidal wave trajectory and suppressing the vibration of a Two Link Flexible Manipulator (TLFM). The TLFM was modeled using Lagrange's formalism and the Assumed Mode Method (AMM). A three-part apparatus consisting of a TLFM mathematical model, a real-world TLFM, and control software was designed and implemented. … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 11 May 2023 · 6,169 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeat Transfer Enhancement of Small Scale Heat Sinks Using Vibrating Pin FinSuabsakul Gururatana, Xianchang LiHeat sinks are widely adopted in electronics cooling together with different technologies to enhance the cooling process. For the small electronics application, the small scale pin fins heat sinks are extensively used to dissipate heat in electronics devices. Due to the limit of space in the small devices, it is impossible to increase heat transfer area. In order to improve … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStructural Analysis of DNA Interactions with Magnesium Ion Studied by Raman SpectroscopyS. Ponkumar, P. Duraisamy, N. IyanduraiProblem statement: In the present study, FT Raman spectroscopy had been used to extend our knowledge about Magnesium ion - DNA interactions at various volume ratios (1:50, 1:20, 1:10 and 1:5). Approach: The analysis of FT Raman data supported the existence of structural specificities in the interaction and also the stability of DNA secondary structure. Results: Results from the Raman … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 28 Nov 2011 · 8,679 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTesting and Performance Evaluation of Tractor Mounted Hydraulic Elevator for Mango OrchardKishor P. Kolhe, Bhaskhar B. JadhavProblem statement: The harvesting and pruning of horticultural crops is quite difficult due to their tallness. There are small hand tools available for harvesting and pruning. But these tools of harvesting and pruning are restricted due tree height, unavailability of trained labours for climbing and cost of operation etc. The mechanized machines are available; these are heavy and costly and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 26 Mar 2011 · 8,887 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeorge (Gogu) ConstantinescuRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.George (Gogu) Constantinescu (October 4, 1891 - December 11, 1965) was a Romanian scientist and engineer, often considered to be one of the most important Romanian engineers. He was responsible for creating a new field of mechanics, called "sonicity," which describes the transmission of energy through vibrations in fluid or solid bodies. He applied the new theory to numerous inventions: … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Dec 2017 · 8,571 accessesView PDFCite
Review ArticleOpen accessIn the keywordsAbout Homeopathy or ≪Similia Similibus Curentur≫Raffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuHomeopathy or homoeopathy (from the Greek όμοιος/homoios, "similar" and πάθος/pathos, "suffering" or "disease") is a science created by Samuel Hahnemann in 1796. The homeopathic practice rests on three principles: The similarity, the individualization of cases and the infinitesimal. The use of the infinitesimal was proposed by Hahnemann in the early nineteenth century with the publication of "Organon der Heilkunst" (Organon … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 16 Dec 2016 · 11,553 accessesView PDFCite

Research ArticleOpen accessIn the keywordsMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDFCite
