J Electr Eng Technol.2018; 13(4): 1697-1704 ISSN(Print) 1975-0102 http://doi.org/10.5370/JEET.2018.13.4.1697 ISSN(Online) 2093-7423 Analysis on Electric Field Based on Three Dimensional Atmospheric Electric Field Apparatus Hong-yan Xing†, Gui-xian He* and Xin-yuan Ji** Abstract – As a key component of lighting location system (LLS) for lightning warning, the atmospheric electric field measuring is required to have high accuracy. The Conventional methods of the existent electric field measurement meter can only detect the vertical component of the atmospheric electric field, which cannot acquire the realistic electric field in the thunderstorm. This paper proposed a three dimensional (3D) electric field system for atmospheric electric field measurement, which is capable of three orthogonal directions in X, Y, Z, measuring. By analyzing the relationship between the electric field and the relative permittivity of ground surface, the permittivity is calculated, and an efficiency 3D measurement model is derived. On this basis, a three-dimensional electric field sensor and a permittivity sensor are adopted to detect the spatial electric field. Moreover, the elevation and azimuth of the detected target are calculated, which reveal the location information of the target. Experimental results show that the proposed 3D electric field meter has satisfactory sensitivity to the three components of electric field. Additionally, several observation results in the fair and thunderstorm weather have been presented. Keywords: Three dimension electric field, Permittivity sensor, Lightning, Electric field analysis. 1. Introduction cloud, which changes with the clouds changes [8]. So, there will be an existence of horizontal components of Monitoring of the atmosphere electric field is an the electric field other than the vertical component. -
Nuclear Fusion with Coulomb Barrier Lowered by Scalar Field
Issue 3 (October) PROGRESS IN PHYSICS Volume 15 (2019) Nuclear Fusion with Coulomb Barrier Lowered by Scalar Field T. X. Zhang1 and M. Y. Ye2 1Department of Physics, Chemistry, and Mathematics, Alabama A & M University, Normal, Alabama 35762, USA. E-mail: [email protected] 2School of Physical Science, University of Science and Technology of China, Hefei, Anhui 230088, China. E-mail: [email protected] The multi-hundred keV electrostatic Coulomb barrier among light elemental positively charged nuclei is the critical issue for realizing the thermonuclear fusion in laborato- ries. Instead of conventionally energizing nuclei to the needed energy, we, in this paper, develop a new plasma fusion mechanism, in which the Coulomb barrier among light elemental positively charged nuclei is lowered by a scalar field. Through polarizing the free space, the scalar field that couples gravitation and electromagnetism in a five- dimensional (5D) gravity or that associates with Bose-Einstein condensates in the 4D particle physics increases the electric permittivity of the vacuum, so that reduces the Coulomb barrier and enhances the quantum tunneling probability and thus increases the plasma fusion reaction rate. With a significant reduction of the Coulomb barrier and enhancement of tunneling probability by a strong scalar field, nuclear fusion can occur in a plasma at a low and even room temperatures. This implies that the conventional fusion devices such as the National Ignition Facility and many other well-developed or under developing fusion tokamaks, when a strong scalar field is appropriately estab- lished, can achieve their goals and reach the energy breakevens only using low-techs. -

This book or parts thereof may not be reproduced in any form or in any language without permission of the publisher. Library of Congress Catalog Card No. 59-15913 Printed in the United States of America PREFACE The concepts of magnetism and electromagnetism form such an essential part of the study of electronic theory that the serious student of this field must have a complete understanding of these principles. The considerations relating to magnetic theory touch almost every aspect of electronic development. This book is the second of a two-volume treatment of the subject and continues the attention given to the major theoretical con siderations of magnetism, magnetic circuits and electromagnetism presented in the first volume of the series.• The mathematical techniques used in this volume remain rela tively simple but are sufficiently detailed and numerous to permit the interested student or technician extensive experience in typical computations. Greater weight is given to problem solutions. To ensure further a relatively complete coverage of the subject matter, attention is given to the presentation of sufficient information to outline the broad concepts adequately. Rather than attempting to cover a large body of less important material, the selected major topics are treated thoroughly. Attention is given to the typical practical situations and problems which relate to the subject matter being presented, so as to afford the reader an understanding of the applications of the principles he has learned. -
Modelling and Simulation of a Simple Homopolar Motor of Faraday's Type
FACTA UNIVERSITATIS (NIS)ˇ SER.: ELEC. ENERG. vol. 24, no. 2, August 2011, 221-242 Modelling and Simulation of a Simple Homopolar Motor of Faraday's Type Dedicated to Professor Slavoljub Aleksic´ on the occasion of his 60th birthday Hartmut Brauer, Marek Ziolkowski, Konstantin Porzig, and Hannes Toepfer Abstract: During the application of simulation tools of computational electromag- netics it is sometimes difficult to decide whether the problems can be solved by the computation of electromagnetic fields or circuit simulation tools have to be applied ad- ditionally. The paper describes a typical situation in an electromagnetic CAD course, not only for beginners. The modelling and numerical simulation of a simple homopo- lar motor, similar to that what has been presented by Michael Faraday in 1821 firstly, was used as an example. To simulate the current flow in the permanent magnet the FEM software codes COMSOL Multiphysics including the integrated SPICE module and MAXWELL have been used. The correct simulation of the entire electric circuit as well as the precise modelling of the impressed current and of the electrode contacts turned out to be very important. Keywords: Homopolar motor; homopolar generator; Faraday’s motor principle; FEM software. 1 Introduction S is so often the case with invention, the credit for development of the elec- A tric motor is belongs to more than one individual.

The Coulomb Barrier Not Static in QED," a Correction to the Theory by Preparata on the Phenomenon of Cold Fusion and Theoretical Hypothesis
Frisone, F. "The Coulomb Barrier not Static in QED," A correction to the Theory by Preparata on the Phenomenon of Cold Fusion and Theoretical hypothesis. in ICCF-14 International Conference on Condensed Matter Nuclear Science. 2008. Washington, DC. “The Coulomb Barrier not Static in QED” A correction to the Theory by Preparata on the Phenomenon of Cold Fusion and Theoretical hypothesis Fulvio Frisone Department of Physics of the University of Catania Catania, Italy, 95125, Via Santa Sofia 64 Abstract In the last two decades, irrefutable experimental evidence has shown that Low Energy Nuclear Reactions (LENR) occur in specialized heavy hydrogen systems [1-4]. Nevertheless, we are still confronted with a problem: the theoretical basis of LENR are not known and, as a matter of fact, little research has been carried out on this subject. In this work we seek to analyse the deuteron-deuteron reactions within palladium lattice by means of Preparata’s model of the palladium lattice [5,15]. We will also show the occurrence probability of fusion phenomena according to more accurate experiments [6]. We are not going to use any of the research models which have been previously followed in this field. Our aim is to demonstrate the theoretical possibility of cold fusion. Moreover, we will focus on tunneling the existent Coulomb barrier between two deuterons. Analysing the possible contributions of the lattice to the improvement of the tunneling probability, we find that there is a real mechanism through which this probability could be increased: this mechanism is the screening effect due to d-shell electrons of palladium lattice. -

In this study, contact electrification and electrostatic interactions during powder handling processes are explored using the discrete element method coupled with computational fluid dynamics (DEM-CFD), in which contact electrification and electrostatic interaction models are developed and implemented. The effects of particle shape on contact electrification are also investigated, for which multi-sphere methods are adapted and implemented into the DEM-CFD. The electrostatic and dynamic behaviours in various powder handling processes are then analyzed, which include contact electrification of spherical particles during fluidization; electrostatic interactions during deposition of mono-charged and bi-charged particles; contact electrification and electrostatic interactions of spherical particles during fluidization; contact electrification of elongated particles in a vibrating container and particles of arbitrary shapes in a rotating drum.
