Research ArticleOpen accessIn the keywordsAbout the Light DimensionsFlorian Ion T. Petrescu, John Kaiser CalautitLight is one of the most fascinating something of all the time. This paper aims to develop a tool with which one can determine with great accuracy the dimensions of light. Basically was entered a new relationship through which one may determine the size of a photon depending on the wavelength of light. Instead wavelength of light can be used … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 10,611 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElectron DimensionsRelly Victoria Virgil Petrescu, Raffaella Aversa, Shuhui Li et al.In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 7,576 accessesView PDFCite
Review ArticleOpen accessIn the keywordsSomething about Electron DimensionRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella et al.In this study will be exposed the theoretical principles necessary for the determination of the exact size of an electron in motion, depending on its speed of travel. Equations, aimed to accurately determines the radius R of the electron in motion, relating the electron moving speed v and its rest mass m0 are discussed.

Research ArticleOpen accessIn the abstractShift of Zeeman Components of Ionic Spectral Lines Caused by the Angular Doppler EffectEugene OksThe angular Doppler effect was introduced by Garetz. While the usual Doppler effect is caused by the translational motion of the emitter, the angular Doppler effect is caused by the rotational motion of the emitter. It results into the frequency shift of a circularly-polarized light. In the present paper we analyze the angular Doppler effect caused by the rotational motion … …Physics International, Vol. 15, Issue 1 · 16 Jun 2025 · 6,449 accessesView PDFCite
Review ArticleOpen accessIn the abstractDDoS Mitigation Using Machine Learning in Software-Defined NetworksAhmed Gaber Abu Abd-Allah, Noureldin Omar Mohamed, Mohamed Samir Mohamed et al.With the escalating frequency and sophistication of Distributed Denial of Service (DDoS) attacks, the realm of cyber security has witnessed a paradigm shift towards innovative solutions. This review explores the potential of machine learning as a powerful defense mechanism in the field of DDoS mitigation within Software-Defined Networks (SDNs). The study methodically examines a variety of machine learning algorithms used … …Journal of Computer Science, Vol. 21, Issue 4 · 23 Mar 2025 · 6,774 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 abstractNanoscale Pitch Standards Sample Fabricated using Laser-Focused Atomic DepositionYan Ma, Tongbao Li, Yajun Zhao et al.Problem statement: Nanotechnology is already a large sector of industry and science research and it is expected to continue to grow at very fast rate. The determination of absolute measurements of length at the nanometer scale and below is very difficult and expensive. So the nanoscale metrology standard is needed. Approach: The laser-focused atomic deposition is a new way to … …Current Research in Nanotechnology, Vol. 2, Issue 2 · 3 Sep 2012 · 7,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation and Implementation of Quasi Resonant DC-DC ConverterP. Parvathy, N. DevarajanProblem statement: A half-bridge LLC resonant converter with a voltage doubler rectifier has a simple structure and its Zero-Voltage-Switching (ZVS) capability is excellent from zero to full load condition. But conduction loss is more due to high circulating energy thus reducing the system efficiency. Moreover a variable frequency control method makes the control circuits more complicated than those using the … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 7,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Performance of a Dual Header Pulse Interval Modulation in the Presence of Artificial Light Interferences in an Indoor Optical Wireless Communications Channel with Wavelet DenoisingS. Rajbhandari, Z. Ghassemlooy, M. AngelovaProblem statement: Similar to other baseband modulation schemes, the performance of the Dual Header Pulse Interval Modulation (DH-PIM) is adversely affected by Artificial Light Interferences (ALI) in an indoor Optical Wireless Communications (OWC) channel. Approach: The Discrete Wavelet Transform (DWT) based denoising is studied for reducing the effect of the ALI. Computer simulation is carried out to demonstrate the effectiveness … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 7,780 accessesView PDFCite
