Research ArticleOpen accessIn the abstractGeorge (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 abstractAbout Boeing X-32Relly Victoria Virgil PetrescuThe Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 1 Apr 2019 · 9,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Environmental Change on Human Health: A Descriptive Economic AnalysisUttam Paudel, Shiva Raj Adhikari, Krishna Prasad PantEnvironmental dilapidation in developing countries upsurges the incidence of human diseases leading to societal impoverishment in the disease rampant areas. Literatures on economic evaluation of effects of environmental changes on human health are scanty. This paper descriptively reconnoiters major environmental changes, spread of diseases, associated household cost including health costs and finally benefits from the improvement of environment through household … …American Journal of Environmental Sciences, Vol. 14, Issue 6 · 7 Jan 2019 · 8,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluenza Surveillance in Russia Based on Epidemiological and Laboratory Data for the Period from 2005 to 2012Sominina Anna, Elena Burtseva, Mikhail Eropkin et al.Exchange of information on and sharing of influenza viruses through the GISRS network has great significance for understanding influenza virus evolution, recognition of a new pandemic virus emergence and for preparing annual WHO recommendations on influenza vaccine strain composition. Influenza surveillance in Russia is based on collaboration of two NICs with 59 Regional Bases. Most epidemiological and laboratory data are … …American Journal of Infectious Diseases, Vol. 9, Issue 3 · 14 Oct 2013 · 8,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Coastal Current of the Andaman Sea Revealed by Reprocessed ObservationsSakharin Suwannathatsa, Prungchan Wongwises, Worachat Wannawong, Suphat VongvisessomjaiProblem statement: The surface currents in the Andaman Sea are observed and quantified by many studies in opposite of the local coastal current that is unclear. Knowing the contributor to this local current improves the simulation work in the most accurate way. This study reviews reprocessed observations from satellites and creates an oceanic model by taking data of 1995 to … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 22 May 2012 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow to Find Wave-Scattering Parameters from the Causal Bond Graph Model of a High Frequency FilterHichem Taghouti, Abdelkader MamiProblem statement: The aim of this study is to use the bond graph technique and the wave-scattering formalism, jointly, to determine the scattering matrix of a high frequency filter with cut-off frequency 10 GHz. Approach: The first step consist to model the high frequency filter by bond graph approach, afterward, we decomposed the obtained causal bond graph model under an … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractWave V Detection Using Instantaneous Energy of Auditory Brainstem Response SignalM. M. Rushaidin, Sh-Hussain Salleh, Tan Tian Swee et al.Problem statement: ABR machine is a well known machine that has been used on detection of hearing problem especially for babies or children. In ABR, wave V is the most prominent and robust wave that has been used as indicator of hearing loss. However, a fast detection of the wave V is necessary in order to implement newborn hearing screening. … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change in Jordan: A Comprehensive Examination ApproachMoshrik R. Hamdi, Mahmoud Abu-Allaban, Ammar Al-Shayeb et al.Problem statement: Jordan is experiencing harsh water shortage in different parts of the country due to high fluctuations in annual precipitation; the only source of water. In addition, heat waves are becoming more frequent in the region. Precipitation decrement and summer heat waves are being blamed on global warming. This study aimed to detect trends in weather parameters in Jordan. … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 9,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New System to Analyze Pulsatile Flow Characteristics in Elastic Tubes for Hemodynamic ApplicationsAfshin Anssari-Benam, Mohammad Tafazzoli-Shadpour, Nasser Fatouraee et al.In this research, we present a new designed experimental setup for study of characteristics of pulsatile flow in elastic tubes, aiming to simulate arterial blood flow. This system includes four major components: (1) a pulsatile pump producing original arterial flow, (2) an elastic element to simulate coupling of the heart with the arterial system, (3) an elastic tube with mechanical … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,009 accessesView PDFCite
