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
Case ReportOpen accessIn the abstractAn Economic and Environmental Evaluation of the Em-Ferro Plastic Sorting TechnologySeyedehfarzaneh Nojabaei, Omid Nematshahi, Matthew FranchettiRecycling has been continually practiced since the dawn of mankind; however, increasing production costs as well as environmental impacts of the conventional waste disposal methods have shed a light on the importance of recycling as a sustainable way to produce goods and services. Recycling has proven to be beneficial, economically and environmentally: It saves resources, prevents pollution, supports public health … …American Journal of Economics and Business Administration, Vol. 7, Issue 1 · 30 May 2015 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractMODELING THE UNIVERSE AS A QUANTUM WELLMichael Harney, Julie SealBy modeling the Universe as a quantum well for standing waves and solving Schrodinger’s equation for a particle trapped in this well, the solutions for the allowable rest-energies of all particles in the Universe are obtained, from the mass of the photon up to the mass of the Universe. The quantum numbers that predict the allowable rest-energies of all particles … …Physics International, Vol. 5, Issue 1 · 19 Mar 2014 · 8,241 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN APPLICATION SPECIFIC WINDOWS MANAGEMENT INSTRUMENTATION ARCHITECTURE FOR IMPROVING PERFORMANCE ON WIRELESS NETWORKLavanya Sankara Narayanan, Murali Baskaran VenugopalWireless Communications is one of the fastest growing segments in the communications industry. Wireless Network is the network that facilitates communication among two or more computers connected through the standard network protocols, without network cabling. Generally, the Wireless Network is termed as Wireless Local Area Networks (WLAN). A WLAN is a collection of network components connected by electromagnetic (radio) waves … …Journal of Computer Science, Vol. 10, Issue 3 · 28 Nov 2013 · 6,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcceleration and Particle Field Interactions of Cosmic Rays: FormalismA. Tawfik, A. Saleh, M.T. Ghoneim, A.A. HadyThe origin and acceleration theories of Ultrah High Energy Cosmic Rays (UHECRs) are still mesterious problem in modern physics and astrophysics. The acceleration of ultra high energy cosmic rays is conjectured to occur through interactions with electromagnetic fields in different astrophysical objects, like magnetic matter clumps, besides the well-known shock waves and elastic Fermi mechanisms. Based on this model, a … …Physics International, Vol. 3, Issue 2 · 18 May 2013 · 7,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractDielectric Properties of Ni0.2Zn0.8Fe2O4-Polypropylene CompositesTan Foo Khoon, Jumiah Hassan, Nurhidayaty Mokhtar et al.Problem statement: In the last decade, the studies and investigation on polymer-based composites have drawn significant attention owing to improvement in their mechanical, thermal, electrical, optical and pharmaceutical properties as compared with pure polymer. Approach: Different compositions of Ni0.2Zn0.8Fe2O4 (NZF) and Polypropylene (PP) can alter the useful properties of polymer-based composites. Hence, the determination toward significant percentage of NZF added … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,947 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Properties of 3/2ω0 and 2ω0 Harmonics Emission from Laser Driven PlasmasA.S.A. Dib, A.H. BelbachirUsing a simple model based on the conversion of electron plasma waves into electromagnetic waves through a process of parametric interaction of four waves, the general properties of the 3/2ω0 emission and the 2ω0 emission generated by the interaction of a Gaussian laser pulse with homogeneous plasma are studied. Some known characteristics of these emissions are reproduced within this model … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Charaterization of Magnesium Zinc Ferrites as Electromagnetic SourceNoorhana Yahya, Ami Salwani Mohamad Nor Aripin, Azizuddin A. Aziz et al.Fabrication of Mg1-XZnXFe2O4 (where x = 0.2, 0.3, 0.4 and 0.5) samples using a conventional technique is reported. Oxides of magnesium, zinc and iron with purity of about 99.99% were mixed with distilled water in a milling machine for 12 hours. They were then filtered and presintered at 1250°C and sintered at 1350°C for 10 h in air. The phase … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 8,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractInformatics and Physics Models of Recognitions of DNA Replication and Their Biological ApplicationsKang Cheng, Chang Hua ZouWe initially propose concepts of Informative Intensity, Informative Response Intensity and Informative Flux, with different expressions. In a special expression of electrostatics, we describe Informative Intensity, Informative Response Intensity and Informative Flux in terms of electric field intensity, electric field force and electric field flux respectively. In a special expression of quantum mechanics, we originally propose a concept of Probability … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,869 accessesView PDFCite
