Download or read book Drones Surveillance and Targeted Killings written by Anne C. Cunningham and published by Greenhaven Publishing LLC. This book was released on 2016-12-15 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely anthology examines the use of drones by the military, law enforcement, border patrol, and civilians. Articles condoning the use of drones in military engagements abroad are balanced with reportage of civilian deaths and resulting creation of more terrorists. Pieces touting the effectiveness of drones in domestic surveillance are countered by assertions that they violate Americans’ civil liberties. Opinions about the pros and cons of drone use in securing our borders, as well as the potential benefits and dangers of their commercial use, will add to readers’ deep understanding of this complex issue.

Download or read book The Hidden Variables Theory The Initial Values of the Fundamental Constants in Physics written by Israel Fried and published by Lulu.com. This book was released on 2009-08-25 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this revision: The electric charge of a subatomic particle is originated from its Orbital Angular Momentum (OAM). The electron mass is a magnitude that expresses quantitatively the square of its magnetic flux quantum. The proton, the neutron and all baryons consist of three energy levels on which the quarks are orbiting. The third energy level is equivalent to 80.5 Gev; it plays a role at decaying process through the weak force. The quark's OAM is a third or two thirds of the reduced Planck constant. The proton's missing spin is resolved by quarks OAM contribution. The electron is a bound state composition of a negative Pion and an electron Neutrino. The theory predicts a neutral boson of 160Gev (alongside to W+ boson from a 240Gev decaying particle). The 2007 data analysis at CDF (Tevatron) showed this possibility. Apparently this was a valid finding despite the final results.The 240Gev particle can also decay to two W+ and one W- Bosons instead of 160Gev Boson which makes it hard to be detected.

Download or read book Generation Transmission Detection and Application of Vortex Beams written by Xizheng Ke and published by Springer Nature. This book was released on 2023-05-27 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the key technologies supporting orbital-angular-momentum multiplexing communication: generation, transmission, detection, and application of vortex beams. A series of methods for generating vortex beams are described and compared in detail. Laguerre-Gaussian and Bessel-Gaussian beams are taken as examples to introduce the transport properties of vortex beams in atmospheric turbulence. The authors show that superposition of vortex beam state, interference, diffraction, and grating can realize the detection of the topological charge of vortex beams. The authors also introduce the application of vortex beams in optical communication and the transmission characteristics of partially coherent vortex beams in atmospheric turbulence. Finally, the authors describe vortex beam information exchange and channel reconstruction.

Download or read book Vortex Atom The A New Paradigm written by Barry R Clarke and published by World Scientific. This book was released on 2021-03-11 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: With clear illustrations throughout and without recourse to quantum mechanics, the reader is invited to revisit unsolved problems lying at the foundations of theoretical physics. Maxwell and his contemporaries abandoned their search for a geometrical representation of the electric and magnetic fields. The wave-particle dilemma and Bose-Einstein statistical counting have resulted in unsatisfactory non-realistic interpretations. Furthermore, a simple structure of the hydrogen atom that includes hyperfine levels is still wanting.Working with the latest experimental data in photonics a proposed solution to the wave-particle dilemma is suggested based on an array of circular-polarized rays. The Bose-Einstein counting procedure is recast in terms of distinguishable elements. Finally, a vortex model of a 'particle' is developed based on a trapped photon. This consists of a single ray revolving around a toroidal surface, and allows a geometrical definition of mass, electric potential, and magnetic momentum. With the adjustment of two parameters, values to 4 dp for the hyperfine frequencies (MHz) of hydrogen can be obtained for which a computer program is available.
