The aim of this work shows a numerical simulation of the electromagnetic field of 400 kV line after perforation through a ferrous nail in four positions for the pinch pin at different distances. From results for a longitudinal section, we observe and evaluate the distribution and the variation of the electromagnetic field in the cable and the earth. When the nail approaches the underground power cable, the distribution of the magnetic field changes and takes several forms, the magnetic field increase and become very important when the nail breaks the metal screen and will produce a significant leak of the electric field, characterized by a large electric arc and or electric discharge to earth and then a fault in the electrical network.

The effect of electromagnetic fields on the efficiency of the capacitive deionization (CDI) process was investigated experimentally. The results showed that treating the feed stream of the CDI process using an electromagnetic field can enhance the electrosorption capacity from 20% up to 70%. The effect of the degree of time of exposure, concentration, and type of ions have been examined. The electromagnetic field enhanced the salt adsorption capacity (SAC) of the Ca²⁺ ions by 70%, while the SAC enhanced 20% to the Na⁺ ions. It is hypnotized that the electrometric field affects the hydration shell around the ions and thus reduces their effective size and enhances the mass transfer. This reduction in ion effective size and increase in mass transfer enhanced the electrosorption capacity and kinetics of the CDI process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitive%20deionization" title="capacitive deionization">capacitive deionization</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20treatment" title=" electromagnetic treatment"> electromagnetic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment"> water treatment</a> </p> <a href="https://publications.waset.org/abstracts/134804/effect-of-electromagnetic-field-on-capacitive-deionization-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134804.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8608</span> Characterization of Complex Electromagnetic Environment Created by Multiple Sources of Electromagnetic Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clement%20Temaneh-Nyah">Clement Temaneh-Nyah</a>, <a href="https://publications.waset.org/abstracts/search?q=Josiah%20Makiche"> Josiah Makiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Nujoma"> Josephine Nujoma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers the characterisation of a complex electromagnetic environment due to multiple sources of electromagnetic radiation as a five-dimensional surface which can be described by a set of several surface sections including: instant EM field intensity distribution maps at a given frequency and altitude, instantaneous spectrum at a given location in space and the time evolution of the electromagnetic field spectrum at a given point in space.

In this paper, we try to give a comprehensive approach to calculate the impact of the ground on the radiated electromagnetic fields to lightning. The vertical component of lightning electric field is calculated with a reasonable approximation assuming a perfectly conducting ground in case the observation point does not exceed a few kilometres from the lightning channel. However, for distant observation points the radiated vertical component of lightning electric field is attenuated due finitely conducting ground. The attenuation is calculated using the expression elaborated for both low and high frequencies. The horizontal component of the electric field, however, is more affected by a finite conductivity of a ground. Besides, the contribution of the horizontal component of the electric field, to induced voltages on an overhead transmission line, is greater than that of the vertical component. Therefore, the calculation of the horizontal electric field is great concern for the simulation of lightning-induced voltages. For field to transmission lines coupling the ground impedance is calculated for early time behaviour and for low frequency range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20engineering" title="power engineering">power engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=radiated%20electromagnetic%20fields" title=" radiated electromagnetic fields"> radiated electromagnetic fields</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning-induced%20voltages" title=" lightning-induced voltages"> lightning-induced voltages</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20electric%20field" title=" lightning electric field"> lightning electric field</a> </p> <a href="https://publications.waset.org/abstracts/7041/a-comprehensive-approach-in-calculating-the-impact-of-the-ground-on-radiated-electromagnetic-fields-due-to-lightning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7041.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">404</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8606</span> Therapeutic Application of Light and Electromagnetic Fields to Reduce Hyper-Inflammation Triggered by COVID-19 </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blanche%20Aguida">Blanche Aguida</a>, <a href="https://publications.waset.org/abstracts/search?q=Marootpong%20Pooam"> Marootpong Pooam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Jourdan"> Nathalie Jourdan</a>, <a href="https://publications.waset.org/abstracts/search?q=Margaret%20Ahmad"> Margaret Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> COVID-19-related morbidity is associated with exaggerated inflammation and cytokine production in the lungs, leading to acute respiratory failure. The cellular mechanisms underlying these so-called ‘cytokine storms’ are regulated through the Toll-like receptor 4 (TLR4) signaling pathway and by reactive oxygen species (ROS). Both light (photobiomodulation) and magnetic fields (e.g., pulsed electromagnetic field) stimulation are non-invasive therapies known to confer anti-inflammatory effects and regulate ROS signaling pathways. Here we show that daily exposure to two 10-minute intervals of moderate-intensity infra-red light significantly lowered the inflammatory response induced via the TLR4 receptor signaling pathway in human cell cultures. Anti-inflammatory effects were likewise achieved by electromagnetic field exposure of cells to daily 10-minute intervals of either pulsed electromagnetic fields (PEMF) or to low-level static magnetic fields. Because current illumination and electromagnetic field therapies have no known side effects and are already approved for some medical uses, we have here developed protocols for verification in clinical trials of COVID 19 infection. These treatments are affordable, simple to implement, and may help to resolve the acute respiratory distress of COVID 19 patients both in the home and in the hospital. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID%2019" title="COVID 19">COVID 19</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20fields%20therapy" title=" electromagnetic fields therapy"> electromagnetic fields therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=photobiomodulation%20therapy" title=" photobiomodulation therapy"> photobiomodulation therapy</a> </p> <a href="https://publications.waset.org/abstracts/135632/therapeutic-application-of-light-and-electromagnetic-fields-to-reduce-hyper-inflammation-triggered-by-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135632.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8605</span> Electromagnetic Source Direction of Arrival Estimation via Virtual Antenna Array</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meiling%20Yang">Meiling Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuguo%20Xie"> Shuguo Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Yilong%20Zhu"> Yilong Zhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, due to diverse electric products and complex electromagnetic environment, the localization and troubleshooting of the electromagnetic radiation source is urgent and necessary especially on the condition of far field.

The study was mainly dedicated to illustrate the effect of application of electromagnetic field (EMF) on the rate of cementation. The magnetic flux was placed parallel to the iron rod and different magnetic field strength was studied. The results showed that without EMF, the rate of mass transfer was correlated by the equation: Sh= 1.36 Re0. 098 Sc0.33. The application of EMF enhanced the time required to reach high percentage copper cementation by 50%. The rate of mass transfer was correlated by the equation: Sh= 2.29 Re0. 95 Sc0.33, with applying EMF. This work illustrates that the enhancement of copper recovery in presence of EMF is due to the induced motion of Fe+n in the solution which is limited in the range of rod rotation speed of 300~900 rpm. The calculation of power consumption of EMF showed that although the application of EMF partially reduced the cementation time, the reduction of power consumption due to utilization of magnetic field is comparable to the increase in power consumed by introducing magnetic field of 2462 A T/m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper%20cementation" title="copper cementation">copper cementation</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20field" title=" electromagnetic field"> electromagnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20ions" title=" copper ions"> copper ions</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20cylinder" title=" iron cylinder"> iron cylinder</a> </p> <a href="https://publications.waset.org/abstracts/17981/parallel-magnetic-field-effect-on-copper-cementation-onto-rotating-iron-rod" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17981.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8603</span> Hypothesis about the Origin of the Lighting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Kuzminov">Igor Kuzminov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Till now, the nature of lightning is not established. A hypothesis of the origin of lightning is proposed. The lightning charge is formed by electromagnetic induction. The role of the conductor is performed by the air mass of the cloud. This conductor moves in the Earth's magnetic field. The upper and lower edges of the cloud are the plates of the capacitor. Lightning is a special case of electromagnetic processes in an atmosphere. The category of lightning occurs in the process of accumulation of a charge. The process of accumulation goes constantly, but the charge is not fixed. Naturally, the hypothesis demands the carrying out of additional experiments and official acknowledgement.

Though regulatory bodies provide guidelines for exposure, people still exercise fear on the possible health hazard that may result due to long term usage. In this study, exposure due to electromagnetic field emitted by GSM base stations in industrial areas was investigated. The aimed was to determine whether industrial area exposure is higher as compared to residential as well as compliance with ICNIRP guidelines. Influence of reflection and absorption with respect to inverse square law was also investigated. Measurements from GSM base stations were performed at various distances in far field region. The highest measured peak power densities as well as the calculated values at GSM 1.8 GHz were 6.05 and 90 mW/m2 respectively. This corresponds to 0.07 and 1% of ICNIRP guidelines. The highest peak power densities as well as the calculated values at GSM 0.9 GHz were 11.92 and 49.7 mW/m2 respectively. These values were 0.3 and 1.1% of ICNIRP guidelines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Global%20System%20for%20Mobile%20Communications%20%28GSM%29" title="Global System for Mobile Communications (GSM)">Global System for Mobile Communications (GSM)</a>, <a href="https://publications.waset.org/abstracts/search?q=Electromagnetic%20Field%20%28EMF%29" title=" Electromagnetic Field (EMF)"> Electromagnetic Field (EMF)</a>, <a href="https://publications.waset.org/abstracts/search?q=far%20field" title=" far field"> far field</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20density" title=" power density"> power density</a>, <a href="https://publications.waset.org/abstracts/search?q=Radiofrequency%20%28RF%29" title=" Radiofrequency (RF) "> Radiofrequency (RF) </a> </p> <a href="https://publications.waset.org/abstracts/13994/exposure-analysis-of-gsm-base-stations-in-industrial-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13994.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">482</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8600</span> Experimental and Theoretical Study of the Electric and Magnetic Fields Behavior in the Vicinity of High-Voltage Power Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tourab%20Wafa">Tourab Wafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nemamcha%20Mohamed"> Nemamcha Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Babouri%20Abdessalem"> Babouri Abdessalem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper consists on an experimental and analytical characterization of the electromagnetic environment in the in the medium surrounding a circuit of two 220 Kv power lines running in parallel.

Due to nonionizing nature and the ability to penetrate several millimeters, THz radiation is suitable for diagnosis of cancerous cells. Traditional THz emitters like optically active crystals, when irradiated with high power laser radiation, are subject to material breakdown and hence low conversion efficiencies. This problem is not encountered in laser-plasma based THz radiation sources. The present paper is devoted to the study of the enhanced electromagnetic radiation generation by propagation of two-color, linearly polarized laser pulses through the magnetized plasma. The two lasers pulse orthogonally polarized are co-propagating along the same direction. The direction of the external magnetic field is such that one of the two laser pulses propagates in the ordinary mode, while the other pulse propagates in the extraordinary mode through the homogeneous plasma. A transverse electromagnetic wave with frequency in the THz range is generated due to the presence of the static magnetic field. It is observed that larger amplitude terahertz can be generated by mixing of ordinary and extraordinary modes of two-color laser pulses as compared with a single laser pulse propagating in the extraordinary mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-color%20laser%20pulses" title="two-color laser pulses">two-color laser pulses</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20radiation" title=" electromagnetic radiation"> electromagnetic radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetized%20plasma" title=" magnetized plasma"> magnetized plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=ordinary%20and%20extraordinary%20modes" title=" ordinary and extraordinary modes"> ordinary and extraordinary modes</a> </p> <a href="https://publications.waset.org/abstracts/53322/electromagnetic-radiation-generation-by-two-color-sinusoidal-laser-pulses-propagating-in-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8597</span> Numerical Analysis of 3D Electromagnetic Fields in Annular Induction Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderazak%20Guettaf">Abderazak Guettaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mathematical models of the physical phenomena interacting in inductive plasma were described by the physics equations of the continuous mediums.

Communications devices, household appliances, industrial equipment, and medical devices all produce EMF radiation with a variety of frequencies, strengths, and ranges. Some EMF radiation, such as Extremely Low Frequency (ELF), Radio Frequency (RF), and the ionizing range have been shown to have harmful effects on human health. Depending on the frequency and strength of the radiation, EMF radiation can have health effects at the cellular level as well as at brain, nervous, and cardiovascular levels. Health authorities have enacted regulations locally and globally to set critical values to limit the adverse effects of EMF radiation. By introducing a more comprehensive field of EMF radiation study and practice, architects and designers can design for a safer electromagnetic (EM) indoor environment, and, as building and construction specialists, will be able to monitor and reduce EM radiation. This paper identifies the nature of EMF radiation in the built environment, the various EMF radiation sources, and its human health effects. It addresses European and US regulations for EMF radiation in buildings and provides a preliminary action plan. The challenges of developing measurement protocols for the various EMF radiation frequency ranges and determining the effects of EMF radiation on building occupants are discussed. This paper argues that a mature method for measuring EMF radiation in building environments and linking these measurements to human health impacts occupant health should be developed to provide adequate safeguards for human occupants of buildings for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20affection" title="biological affection">biological affection</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20field" title=" electromagnetic field"> electromagnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20regulation" title=" building regulation"> building regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20health" title=" human health"> human health</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20building" title=" healthy building"> healthy building</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20construction" title=" clean construction "> clean construction </a> </p> <a href="https://publications.waset.org/abstracts/129637/a-review-of-protocols-and-guidelines-addressing-the-exposure-of-occupants-to-electromagnetic-field-emf-radiation-in-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8595</span> Electromagnetic Interference Shielding Characteristics for Stainless Wire Mesh and Number of Plies of Carbon Fiber Reinforced Plastic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Sang%20Lee">Min Sang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Jae%20Shin"> Hee Jae Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20Pyo%20Cha"> In Pyo Cha</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyung%20Yoon"> Hyun Kyung Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Woo%20Hong"> Seong Woo Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Jae%20Yu"> Min Jae Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Gun%20Kim"> Hong Gun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Ku%20Kwac"> Lee Ku Kwac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the electromagnetic shielding characteristics of an up-to-date typical carbon filler material, carbon fiber used with a metal mesh were investigated.

This paper proposes the implementation of similar technology to aid civil aircraft take-off, which can provide significant economic, environmental and technical benefits. Assisted launch has the potential of reducing ground noise and emissions near airports and improving overall aircraft efficiency through reducing engine thrust requirements. This paper presents a take-off performance analysis for an Airbus A320-200 taking off with and without the assistance of the electromagnetic catapult. Assisted take-off allows for a significant reduction in take-off field length, giving more capacity with existing airport footprints and reducing the necessary footprint of new airports, which will both reduce costs and increase the number of suitable sites. The electromagnetic catapult may allow the installation of smaller engines with lower rated thrust. The consequent fuel consumption and operational cost reduction are estimated. The potential of reducing the aircraft operational costs and the runway length required making electromagnetic launch system an attractive solution to the air traffic growth in busy airports. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20launch" title="electromagnetic launch">electromagnetic launch</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20consumption" title=" fuel consumption"> fuel consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=take-off%20analysis" title=" take-off analysis"> take-off analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20reduction" title=" weight reduction"> weight reduction</a> </p> <a href="https://publications.waset.org/abstracts/56488/reducing-weight-and-fuel-consumption-of-civil-aircraft-by-eml" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56488.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8592</span> Strip Size Optimization for Spiral Type Actuator Coil Used in Electromagnetic Flat Sheet Forming Experiment </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Aleem">M.

Copper strip was chosen as the material for designing the actuator coil. Relationship between height to width ratio (S-factor) of the copper strip and coil’s performance has been studied. Magnetic field intensities, eddy currents, and Lorentz force were calculated for the coils that were designed using six different 'S-factor' values (0.65, 0.75, 1.05, 1.25, 1.54 and 1.75), keeping the cross-sectional area of strip the same. Results obtained through simulation suggest that actuator coil with S-factor ~ 1 shows optimum forming performance as it exerts maximum Lorentz force (84 kN) on work piece. The same coils were fabricated and used for electromagnetic sheet forming experiments. Aluminum 6061 sheets of thickness 1.5 mm have been formed using different voltage levels of capacitor bank. Smooth forming profiles were obtained with dome heights 28, 35 and 40 mm in work piece at 800, 1150 and 1250 V respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEM%20modelling" title="FEM modelling">FEM modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20forming" title=" electromagnetic forming"> electromagnetic forming</a>, <a href="https://publications.waset.org/abstracts/search?q=spiral%20coil" title=" spiral coil"> spiral coil</a>, <a href="https://publications.waset.org/abstracts/search?q=Lorentz%20force" title=" Lorentz force"> Lorentz force</a> </p> <a href="https://publications.waset.org/abstracts/86282/strip-size-optimization-for-spiral-type-actuator-coil-used-in-electromagnetic-flat-sheet-forming-experiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86282.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8591</span> Analysis of the Scattered Fields by Dielectric Sphere Inside Different Dielectric Mediums: The Case of the Source and Observation Point Is Reciprocal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emi%CC%87ne%20Av%C5%9Far%20Aydin">Emi̇ne Avşar Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nezahat%20G%C3%BCnen%C3%A7%20Tuncel"> Nezahat Günenç Tuncel</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Hami%CC%87t%20Serbest"> A.

In this study, the electromagnetic scattering from a dielectric sphere with oblique incidence is investigated. The incident field is considered as a plane wave with H polarized. The scattered and transmitted field expressions with unknown coefficients are written. The unknown coefficients are obtained by using exact boundary conditions. Then, the sphere is considered as having frequency dependent dielectric permittivity. The frequency dependence is shown by Cole-Cole model. The far scattered field expressions are found respect to different incidence angles in the 1-8 GHz frequency range. The observation point is the angular distance of pi from an incident wave. While an incident wave comes with a certain angle, observation point turns from 0 to 360 degrees. According to this, scattered field amplitude is maximum at the location of the incident wave, scattered field amplitude is minimum at the across incident wave. Also, the scattered fields are plotted versus frequency to show frequency-dependence explicitly. Graphics are shown for some incident angles compared with the Harrington's solution. Thus, the results are obtained faster and more reliable with reciprocal rotation. It is expected that when there is another sphere with different properties in the outer sphere, the presence and location of the sphere will be detected faster. In addition, this study leads to use for biomedical applications in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scattering" title="scattering">scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20sphere" title=" dielectric sphere"> dielectric sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20incidence" title=" oblique incidence"> oblique incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=reciprocal%20rotation" title=" reciprocal rotation"> reciprocal rotation</a> </p> <a href="https://publications.waset.org/abstracts/32409/analysis-of-the-scattered-fields-by-dielectric-sphere-inside-different-dielectric-mediums-the-case-of-the-source-and-observation-point-is-reciprocal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8590</span> The Photon-Drag Effect in Cylindrical Quantum Wire with a Parabolic Potential </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Van%20Ngoc">Hoang Van Ngoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Thu%20Huong"> Nguyen Thu Huong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quang%20Bau"> Nguyen Quang Bau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using the quantum kinetic equation for electrons interacting with acoustic phonon, the density of the constant current associated with the drag of charge carriers in cylindrical quantum wire by a linearly polarized electromagnetic wave, a DC electric field and a laser radiation field is calculated.

The possible relation between exposure to (ELF-MFs) and adverse health effects has attracted and passed through long debate sessions. Extremely low frequency is a term used to describe radiation frequencies below 300 Hertz (Hz).It is very important for public health because of the widespread use of electrical power at 50-60 Hz in most countries. This study set out to investigate the impact of chronic exposure of male rats to 50- Hz, 1 mTesla (ELF-EMF) of over periods of 1, 2, and 4 weeks on concentration of serum FSH, LH, and testosterone hormones. 60 male albino rats were divided into 6 groups and were continuously exposed to 50-Hz, 1 m Tesla (ELF-EMF) generated by magnetic field chamber for periods of 1, 2, and 4 weeks. For each experimental point, sham treated group was used as a control. Assay of serum testosterone LH, and FSHwere performed. Serum testosterone showed no significant changes. FSH showed significant increase than sham exposed group after 1 week of field exposure. LH showed significant increase than sham exposed group only after 4 weeks of field exposure. A future detailed molecular studies must be carried out to figure out and may be able to explain the possible interactions between ELF-EMF and hypothalamic-pituitary gonadal axis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extremely%20low%20frequency%20electromagnetic%20fields" title="extremely low frequency electromagnetic fields">extremely low frequency electromagnetic fields</a>, <a href="https://publications.waset.org/abstracts/search?q=testosterone" title=" testosterone"> testosterone</a>, <a href="https://publications.waset.org/abstracts/search?q=follicular%20stimulating%20hormone" title=" follicular stimulating hormone"> follicular stimulating hormone</a>, <a href="https://publications.waset.org/abstracts/search?q=LH" title=" LH "> LH </a> </p> <a href="https://publications.waset.org/abstracts/16414/influence-of-50-hz-1m-tesla-electromagnetic-fields-on-serum-male-sex-hormones-of-male-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16414.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">460</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8588</span> Soil Salinity Mapping using Electromagnetic Induction Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fethi%20Bouksila">Fethi Bouksila</a>, <a href="https://publications.waset.org/abstracts/search?q=Nessrine%20Zemni"> Nessrine Zemni</a>, <a href="https://publications.waset.org/abstracts/search?q=Fairouz%20Slama"> Fairouz Slama</a>, <a href="https://publications.waset.org/abstracts/search?q=Magnus%20Persson"> Magnus Persson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronny%20%20Berndasson"> Ronny Berndasson</a>, <a href="https://publications.waset.org/abstracts/search?q=Akissa%20Bahri"> Akissa Bahri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electromagnetic sensor EM 38 was used to predict and map soil salinity (ECe) in arid oasis.

The operating process of the electromagnetic hammer depends on the circuit scheme of the power controller. Mathematical modeling of the operating process was carried out by considering the energy transfer process in the forward and reverse windings and the electromagnetic force acting on the impact and brake pistons. Using the developed mathematical model, the initial design data of a manual electromagnetic hammer proposed in this paper are encoded and analyzed in Matlab. On the other hand, a measuring experiment was carried out by using a measurement device to check the accuracy of the developed mathematical model. The relative errors of the analytical results for measured stroke distance of the impact piston, peak value of forward stroke current and peak value of reverse stroke current were −4.65%, 9.08% and 9.35%, respectively. Finally, it was shown that the mathematical model of the operating process of an electromagnetic hammer is relatively accurate, and it can be used to determine the design parameters of the electromagnetic hammer. Therefore, the design parameters that can provide the required impact energy in the manual electromagnetic hammer were determined using a mathematical model developed. The proposed method will be used for the further design and development of the various types of percussion rock drills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solenoid%20electromagnet" title="solenoid electromagnet">solenoid electromagnet</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20hammer" title=" electromagnetic hammer"> electromagnetic hammer</a>, <a href="https://publications.waset.org/abstracts/search?q=stone%20processing" title=" stone processing"> stone processing</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a> </p> <a href="https://publications.waset.org/abstracts/187061/mathematical-modeling-of-the-operating-process-and-a-method-to-determine-the-design-parameters-in-an-electromagnetic-hammer-using-solenoid-electromagnets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">45</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8584</span> The Light-Effect in Cylindrical Quantum Wire with an Infinite Potential for the Case of Electrons: Optical Phonon Scattering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoang%20Van%20Ngoc">Hoang Van Ngoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Vu%20Nhan"> Nguyen Vu Nhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Quang%20Bau"> Nguyen Quang Bau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The light-effect in cylindrical quantum wire with an infinite potential for the case of electrons, optical phonon scattering, is studied based on the quantum kinetic equation.

The electromagnetic characterization of the urban zone under study was carried out by measurements in 118 sites. Measurements of TETRA,ISM434, LTE800, ISM868, GSM900, GSM1800, 3G UMTS,4G UMTS, Wlan2.4, LTE2.6, DECT, VHF Television and FM radio signals were performed at distances ranging over 10 to 1000m from 87 broadcasting towers concentrated in an urban area of about 3 hectares. The aim of these measurements is the evaluation of the electromagnetic fields power levels generated by communication systems because of their interaction with the human body. We found that in certain regions the general public exposure limits determined by ICNIRP (International Commission of Non Ionizing Radiation Protection) are overpassed from 5% up to 61% of the upper values, indicating an imminent health public hazard, whereas in other regions we found that these limits are not overpassed. This work proposes an electromagnetic pollution classification for urban zones according with ICNIRP standards. We conclude that the urban zone under study presents diverse levels of pollution and that in certain regions an electromagnetic shielding solution is needed in order to safeguard the health of the population that lives there. A practical solution in the form of paint coatings and fiber curtains for the buildings present in this zone is also proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20field" title="electromagnetic field">electromagnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=telecommunication%20systems" title=" telecommunication systems"> telecommunication systems</a>, <a href="https://publications.waset.org/abstracts/search?q=electropollution" title=" electropollution"> electropollution</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20hazards" title=" health hazards"> health hazards</a> </p> <a href="https://publications.waset.org/abstracts/46590/electromagnetic-fields-characterization-of-an-urban-area-in-lagos-de-moreno-mexico-and-its-correlation-with-public-health-hazards" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46590.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8582</span> Electromagnetic Assessment of Submarine Power Cable Degradation Using Finite Element Method and Sensitivity Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Boutra">N.

Some of the risks are associated with transport, installation and operating in harsh marine environment. This paper describes the feasibility of an electromagnetic low frequency sensing technique for submarine power cable failure prediction. The impact of a structural damage shape and material variability on the induced electric field is evaluated. The analysis is performed by modeling the cable using the finite element method, we use sensitivity analysis in order to identify the main damage characteristics affecting electric field variation. Lastly, we discuss the results obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetism"
