The dielectric constant and tangent loss was measured as a function of frequency from 100Hz to 1MHz at different temperatures (200-500oC). The electrical behavior was then investigated using complex impedance spectroscopy (CIS) technique. From the CIS study, it has been found that there is a contribution of both grain and grain boundary in the electrical behavior of such ceramics. Grain and grain boundary resistivity and capacitance were calculated at different temperature using CIS technique. The present paper is about the discussion of grain and grain boundary contribution towards the electrical properties of Sm modified BaTiO3 based ceramics at high temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grain" title="grain">grain</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20boundary" title=" grain boundary"> grain boundary</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance" title=" impedance"> impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric" title=" dielectric"> dielectric</a> </p> <a href="https://publications.waset.org/abstracts/80702/grain-and-grain-boundary-behavior-of-sm-substituted-barium-titanate-based-ceramics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80702.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">398</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">8265</span> Study of the Tribological Behavior of a Sliding Contact Brass-Steel Couple with Electrical Current</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Boubechou">C.

This study looks at a dry contact brass-steel couple where friction and wear are studied in terms of mechanical and electrical parameters. For this reason, a tribometer, pin-rotary disc is used in an atmospheric atmosphere. The test parameters are as follows: the normal load (5-30N), the sliding speed (0.1 to 0.5 m / s) and the electric current (3-10A). The duration of each test is 30 minutes. The experimental results show that these parameters have a significant effect on the tribological behavior of the couple studied. The discussion of results is based on observations, using an optical microscope, MEB and a profilometer, worn surfaces and interface phenomena resulting from the process of sliding contact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brass-steel%20couple" title="brass-steel couple">brass-steel couple</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20friction" title=" dry friction"> dry friction</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20current" title=" electrical current"> electrical current</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20load" title=" normal load"> normal load</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20speeds" title=" sliding speeds"> sliding speeds</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/38497/study-of-the-tribological-behavior-of-a-sliding-contact-brass-steel-couple-with-electrical-current" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38497.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">267</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">8264</span> Morphology and Electrical Conductivity of a Non-Symmetrical NiO-SDC/SDC Anode through a Microwave-Assisted Route</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohadeseh%20Seyednezhad">Mohadeseh Seyednezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Armin%20Rajabi"> Armin Rajabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Andanastui%20Muchtar"> Andanastui Muchtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahendra%20Rao%20Somalu"> Mahendra Rao Somalu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigates the electrical properties of NiO-SDC/SDC anode sintered at about 1200 ○C for 1h through a relatively new approach, namely the microwave method.

Here author has studied, firstly, behavior of discharges in gaseous dielectric circuit under AC and DC voltages. A gaseous dielectric circuit is made such that a pair of electrode of typical geometry is used to make the discharges occur under application of AC and DC voltages. Later on, composite insulation system with air gap is also studied. Discharge response of the dielectric circuit is measured across a typically designed impedance.

Carbon composite laminates used on aircraft structures are subject to lightning strikes. Unlike its metal/alloy counterparts, carbon fiber reinforced composites demonstrate smaller electrical conductivity, yielding more severe damages due to Joule heating. The anisotropic nature of composite laminates makes the electrical and thermal conduction within carbon composite laminates even more complicated. Good understanding of the electrical conduction behavior of carbon composites is the key to effective lightning protection design. The goal of this study is to numerically and experimentally investigate the impact of ultra-high temperature induced by simulated lightning strike on the electrical conduction of carbon composites. A lightning simulator is designed to apply standard lightning current waveform to composite laminates. Multiple carbon composite laminates made from IM7 and AS4 carbon fiber are tested and the transient resistance data is recorded. A microstructure based resistor network model is developed to describe the electrical and thermal conduction behavior, with consideration of temperature dependent material properties. Material degradations such as thermal and electrical breakdown are also modeled to include the effect of high current and high temperature induced by lightning strikes. Good match between the simulation results and experimental data indicates that the developed model captures the major conduction mechanisms. A parametric study is then conducted using the validated model to investigate the effect of system parameters such as fiber volume fraction, inter-ply interface quality, and lightning current waveforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20composite" title="carbon composite">carbon composite</a>, <a href="https://publications.waset.org/abstracts/search?q=joule%20heating" title=" joule heating"> joule heating</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20strike" title=" lightning strike"> lightning strike</a>, <a href="https://publications.waset.org/abstracts/search?q=resistor%20network" title=" resistor network"> resistor network</a> </p> <a href="https://publications.waset.org/abstracts/76002/impact-of-joule-heating-on-the-electrical-conduction-behavior-of-carbon-composite-laminates-under-simulated-lightning-strike" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76002.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">228</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">8261</span> Analytical Model of Multiphase Machines Under Electrical Faults: Application on Dual Stator Asynchronous Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nacera%20Yassa">Nacera Yassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelmalek%20Saidoune"> Abdelmalek Saidoune</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Ouadfel"> Ghania Ouadfel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Houassine"> Hamza Houassine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapid advancement in electrical technologies has underscored the increasing importance of multiphase machines across various industrial sectors. These machines offer significant advantages in terms of efficiency, compactness, and reliability compared to their single-phase counterparts. However, early detection and diagnosis of electrical faults remain critical challenges to ensure the durability and safety of these complex systems. This paper presents an advanced analytical model for multiphase machines, with a particular focus on dual stator asynchronous machines. The primary objective is to develop a robust diagnostic tool capable of effectively detecting and locating electrical faults in these machines, including short circuits, winding faults, and voltage imbalances. The proposed methodology relies on an analytical approach combining electrical machine theory, modeling of magnetic and electrical circuits, and advanced signal analysis techniques. By employing detailed analytical equations, the developed model accurately simulates the behavior of multiphase machines in the presence of electrical faults. The effectiveness of the proposed model is demonstrated through a series of case studies and numerical simulations. In particular, special attention is given to analyzing the dynamic behavior of machines under different types of faults, as well as optimizing diagnostic and recovery strategies. The obtained results pave the way for new advancements in the field of multiphase machine diagnostics, with potential applications in various sectors such as automotive, aerospace, and renewable energies. By providing precise and reliable tools for early fault detection, this research contributes to improving the reliability and durability of complex electrical systems while reducing maintenance and operation costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faults" title="faults">faults</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20machine" title=" multiphase machine"> multiphase machine</a> </p> <a href="https://publications.waset.org/abstracts/185456/analytical-model-of-multiphase-machines-under-electrical-faults-application-on-dual-stator-asynchronous-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185456.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">64</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">8260</span> A Prediction of Electrical Cost for High-Rise Building Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Picha%20Sriprachan">Picha Sriprachan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in electricity prices affects the cost of high-rise building construction. The objectives of this research are to study the electrical cost, trend of electrical cost and to forecast electrical cost of high-rise building construction. The methods of this research are: 1) to study electrical payment formats, cost data collection methods, and the factors affecting electrical cost of high-rise building construction, 2) to study the quantity and trend of cumulative percentage of the electrical cost, and 3) to forecast the electrical cost for different types of high-rise buildings. The results of this research show that the average proportion between electrical cost and the value of the construction project is 0.87 percent. The proportion of electrical cost for residential, office and commercial, and hotel buildings are closely proportional. If construction project value increases, the proportion of electrical cost and the value of the construction project will decrease. However, there is a relationship between the amount of electrical cost and the value of the construction project. During the structural construction phase, the amount of electrical cost will increase and during structural and architectural construction phase, electrical cost will be maximum. The cumulative percentage of the electrical cost is related to the cumulative percentage of the high-rise building construction cost in the same direction. The amount of service space of the building, number of floors and the duration of the construction affect the electrical cost of construction. The electrical cost of construction forecasted by using linear regression equation is close to the electrical cost forecasted by using the proportion of electrical cost and value of the project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-rise%20building%20construction" title="high-rise building construction">high-rise building construction</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20cost" title=" electrical cost"> electrical cost</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20phase" title=" construction phase"> construction phase</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20phase" title=" architectural phase"> architectural phase</a> </p> <a href="https://publications.waset.org/abstracts/9483/a-prediction-of-electrical-cost-for-high-rise-building-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9483.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">390</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">8259</span> Synchronous Generator in Case Voltage Sags for Different Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benalia%20Nadia">Benalia Nadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bensiali%20Nadia"> Bensiali Nadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Zezouri%20Noura"> Zezouri Noura </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM) when powering an isolate load or infinite bus bar.

Voltage sags on SM cause speed variations, current and torque peaks and hence may cause tripping and equipment damage. The consequences of voltage sags in the machine behavior depends on different factors such as its magnitude (or depth), duration , the parameters of the machine and also the size of load.

The sample was synthesized by the arc-melting method and confirmed to crystallize in the tetragonal α-ThSi₂-type crystal structure with space group I4/amd. Dc– and ac–magnetic susceptibility, specific heat, electrical resistivity, and magnetoresistance measurements were performed on the new compound. The structure provides a unique position in the unit cell for the magnetic trivalent Gd ion. Two magnetic phase transitions were consistently found in dc- and ac-magnetic susceptibility, heat capacity, and electrical resistivity at temperatures Tₙ₁ = 11 K and Tₙ₂ = 20 K, which is an indication of the complex magnetic behavior in this compound. The compound is found to be metamagnetic over a range of temperatures below and above Tₙ₁. From field-dependent electrical resistivity, it is confirmed that the compound shows unusual negative magnetoresistance in the antiferromagnetically ordered region. These results contribute to a better understanding of this class of materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20magnetic%20behavior" title="complex magnetic behavior">complex magnetic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=metamagnetic" title=" metamagnetic"> metamagnetic</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20magnetoresistance" title=" negative magnetoresistance"> negative magnetoresistance</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20magnetic%20phase%20transitions" title=" two magnetic phase transitions"> two magnetic phase transitions</a> </p> <a href="https://publications.waset.org/abstracts/120185/double-magnetic-phase-transition-in-the-intermetallic-compound-gd2agsi3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120185.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">122</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">8257</span> High-Speed Electrical Drives and Applications: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaishnavi%20Patil">Vaishnavi Patil</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20M.%20Kurundkar"> K.

The prepared alloys were heated for 1300 hr to 560oC, and then cooled rapidly by water at the ambient temperature. Surface morphology for alloys is studied by scanning electron microscope (SEM). The resultant homogeneous surface is a result of heat treatment. The X-ray diffraction patterns showed (111), (200), and (220) diffraction lines from cubic Al crystal structure, and suggested that the intensity of peak (111) orientation is predominant. Three binary phases were observed and grown in alloys: Al3Ni (Orthorhombic, a = 6.598Ǻ, b = 7.352 Ǻ, c = 4.802 Ǻ), Cr9Al17 (Rhombohedra, a = 12.910 Ǻ, c = 15.677), and Ni2Cr3 (Tetragonal, a = 8.82 Ǻ, c = 4.58 Ǻ). The average crystallite sizes of the prepared samples were found to be from 3000 to 3094 nm by SEM, which is much smaller than that estimated from XRD data. Corrosion resistance increases with increasing Ni-Cr content in Al alloys. The electrical volume resistivity decreased with increasing Ni-Cr content at low frequency. This behavior can be seen generally at 50Hz, where the electrical volume resistivity reached the value of 3.98×10-8Ω.cm for the ratio Al-1.8 at.%Ni-0.18at.%Cr. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Ni-Cr%20alloy" title="Al-Ni-Cr alloy">Al-Ni-Cr alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20current" title=" corrosion current"> corrosion current</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20volume%20resistivity" title=" electrical volume resistivity"> electrical volume resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20phase" title=" binary phase"> binary phase</a>, <a href="https://publications.waset.org/abstracts/search?q=homogeneous%20surface" title=" homogeneous surface"> homogeneous surface</a> </p> <a href="https://publications.waset.org/abstracts/2784/preparation-and-study-corrosion-and-electrical-resistivity-of-al-ni-cr-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2784.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">397</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">8255</span> Preparation and Properties of PP/EPDM Reinforced with Graphene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Haghnegahdar">M.

Mechanical properties such as tensile strength, impact strength and hardness demonstrated increasing trend by graphene loading which exemplifies substantial reinforcing nature of this kind of nano filler and it's good interaction with polymer chains. At the same time it is found that thermo-oxidative degradation of PP/EPDM nanocomposites is noticeably retarded with the increasing of graphene content. Electrical surface resistivity of the nanocomposite was dramatically changed by forming electrical percolation threshold and leads to change electrical behavior from insulator to semiconductor.

However, the energy density of the commercially used mixtures is still insufficient, and therefore, new systems based on latent heat storage (or phase change materials, PCM) are currently being investigated. In order to shed some light on the macroscopic physical properties of the molten salt phases, knowledge of the microscopic structure and dynamics is required. Several molecular dynamics (MD) simulations have been performed to model the thermal behavior of (Li,K)2CO3 mixtures. Up to this date, this particular molten salt mixture has not been extensively studied but it is of fundamental interest for understanding the behavior of other commercial salts. Molten salt diffusivities, the internal electrical ion mobility, and the physical properties of the solid-liquid phase transition have been calculated and compared to available data from literature. The effect of anion polarization and the application of a strong external electric field have also been investigated. The influence of electrical ion mobility on local composition is explained through the Chemla effect, well known in electrochemistry. These results open a new way to design optimal high temperature energy storage materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomistic%20simulations" title="atomistic simulations">atomistic simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20storage" title=" thermal storage"> thermal storage</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20heat" title=" latent heat"> latent heat</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title=" molten salt"> molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20mobility" title=" ion mobility"> ion mobility</a> </p> <a href="https://publications.waset.org/abstracts/33033/the-effect-of-internal-electrical-ion-mobility-on-molten-salts-through-atomistic-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33033.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">326</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">8253</span> Externalizing Behavior Problems Influencing Social Behavior in Early Adolescence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhidong%20Zhang">Zhidong Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi-Chao%20Zhang"> Zhi-Chao Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on early adolescent externalizing behavioral problems which specifically concentrate on rule breaking behavior and aggressive behavior using the instrument of Achenbach System of Empirically Based Assessment (ASEBA).

Current-voltage measurements were done on a new single-layer ITO/An-FL/Al device of typically 100 nm thickness. Atypical diode behavior is observed with a turn-on voltage of 4.4 V, a dynamic resistance of 74.07 KΩ and a rectification ratio of 2.02 due to unbalanced transport. Results show also that the current-voltage characteristics present three different regimes of the power-law (J~Vᵐ) for which the conduction mechanism is well described with space-charge-limited current conduction mechanism (SCLC) with a charge carrier mobility of 2.38.10⁻⁵cm2V⁻¹S⁻¹. Moreover, the electrical transport properties of this device have been carried out using a dependent frequency study in the range (50 Hz–1.4 MHz) for different applied biases (from 0 to 6 V). At lower frequency, the σdc values increase with bias voltage rising, supporting that the mobile ion can hop successfully to its nearest vacant site. From σac and impedance measurements, the equivalent electrical circuit is evidenced, where the conductivity process is coherent with an exponential trap distribution caused by structural defects and/or chemical impurities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semiconducting%20polymer" title="semiconducting polymer">semiconducting polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=conductivity" title=" conductivity"> conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=SCLC" title=" SCLC"> SCLC</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance%20spectroscopy" title=" impedance spectroscopy"> impedance spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/145828/study-of-electrical-properties-of-an-fl-based-organic-semiconducting-thin-film" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145828.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">179</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">8250</span> Prediction of Index-Mechanical Properties of Pyroclastic Rock Utilizing Electrical Resistivity Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C4%B0smail%20%C4%B0nce">İsmail İnce</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to determine index and mechanical properties of pyroclastic rock in a practical way by means of electrical resistivity method.

The alloy powder coated with un-bundled VGCF by using oil coating process was consolidated at 1223 K in vacuum by spark plasma sintering, and then extruded at 1073 K. The extruded Cu-Cr alloy (monolithic alloy) had 209.3 MPa YS and 80.4 IACS% conductivity. The extruded Cu-Cr with 0.1 mass% VGCF composites revealed a small decrease of YS compared to the monolithic Cu-Cr alloy. On the other hand, the composite had a higher electrical conductivity than that of the monolithic alloy. For example, Cu-Cr with 0.1 mass% VGCF composite sintered for 5 h showed 182.7 MPa YS and 89.7 IACS% conductivity. In the case of Cu-Cr with VGCFs composites, the Cr concentration was observed around VGCF by SEM-EDS analysis, where Cr23C6 compounds were detected by TEM observation. The amount of Cr solid solution in the matrix of the Cu-Cr composites alloy was about 50% compared to the monolithic Cu-Cr sintered alloy, and resulted in the remarkable increment of the electrical conductivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=powder%20metallurgy%20Cu-Cr%20alloy%20powder" title="powder metallurgy Cu-Cr alloy powder">powder metallurgy Cu-Cr alloy powder</a>, <a href="https://publications.waset.org/abstracts/search?q=vapor-grown%20carbon%20fiber" title=" vapor-grown carbon fiber"> vapor-grown carbon fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a> </p> <a href="https://publications.waset.org/abstracts/24251/effect-of-chromium-behavior-on-mechanical-and-electrical-properties-of-pm-copper-chromium-alloy-dispersed-with-vgcf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24251.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">493</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">8248</span> Investigating the Molecular Behavior of H₂O in Caso 4 -2h₂o Two-Dimensional Nanoscale System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Alhazmi">Manal Alhazmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Artem%20Mishchenko"> Artem Mishchenko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A molecular fluids' behavior and interaction with other materials at the nanoscale is a complex process. Nanoscale fluids behave so differently than macroscale fluids and interact with other materials in unique ways. It is, therefore, feasible to understand the molecular behavior of H₂O in such two-dimensional nanoscale systems by studying (CaSO4-2H2O), commonly known as gypsum. In the present study, spectroscopic measurements on a 2D structure of exfoliated gypsum crystals are carried out by Raman and IR spectroscopy. An array of gypsum flakes with thicknesses ranging from 8nm to 100nm were observed and analyzed for their Raman and IR spectrum. Water molecules stretching modes spectra lines were also measured and observed in nanoscale gypsum flakes and compared with those of bulk crystals. CaSO4-2H2O crystals have Raman and infrared bands at 3341 cm-1 resulting from the weak hydrogen bonds between the water molecules. This internal vibration of water molecules, together with external vibrations with other atoms, are responsible for these bands. There is a shift of about 70 cm-1 In the peak position of thin flakes with respect to the bulk crystal, which is a result of the different atomic arrangement from bulk to thin flake on the nano scale. An additional peak was observed in Raman spectra around 2910-3137 cm⁻¹ in thin flakes but is missing in bulk crystal. This additional peak is attributed to a combined mode of water internal (stretching mode at 3394cm⁻¹) and external vibrations. In addition to Raman and infra- red analysis of gypsum 2D structure, electrical measurements were conducted to reveal the water molecules transport behavior in such systems. Electrical capacitance of the fabricated device is measured and found to be (0.0686 *10-12) F, and the calculated dielectric constant (ε) is (12.26). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gypsum" title="gypsum">gypsum</a>, <a href="https://publications.waset.org/abstracts/search?q=infra-red%20spectroscopy" title=" infra-red spectroscopy"> infra-red spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title=" raman spectroscopy"> raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=H%E2%82%82O%20behavior" title=" H₂O behavior"> H₂O behavior</a> </p> <a href="https://publications.waset.org/abstracts/149684/investigating-the-molecular-behavior-of-h2o-in-caso-4-2h2o-two-dimensional-nanoscale-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149684.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">104</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">8247</span> Effect of Al Contents on Magnetic Domains of {100} Grains in Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyunseo%20Choi">Hyunseo Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaewan%20Hong"> Jaewan Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Seil%20Lee"> Seil Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Mo%20Koo"> Yang Mo Koo </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-oriented (NO) electrical steel is one of the most important soft magnetic materials for rotating machines. Si has usually been added to electrical steels to reduce eddy current loss by increasing the electrical resistivity. Si content more than 3.5 wt% causes cracks during cold rolling due to increase of brittleness. Al also increases the electrical resistivity of the materials as much as Si. In addition, cold workability of Fe-Al is better than Fe-Si, so that Al can be added up to 6.0 wt%. However, the effect of Al contents on magnetic properties of electrical steels has not been studied in detail. Magnetic domains of {100} grains in electrical steels, ranging from 1.85 to 6.54 wt% Al, were observed by magneto-optic Kerr microscopy. Furthermore, the correlation of magnetic domains with magnetic properties was investigated. As Al contents increased, the magnetic domain size of {100} grains decreased due to lowered domain wall energy. Reorganization of magnetic domain structure became more complex as domain size decreased. Therefore, the addition of Al to electrical steel caused hysteresis loss to increase. Anomalous loss decreased and saturated after 4.68% Al. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20steel" title="electrical steel">electrical steel</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20domain%20structure" title=" magnetic domain structure"> magnetic domain structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%20addition" title=" Al addition"> Al addition</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20loss" title=" core loss"> core loss</a>, <a href="https://publications.waset.org/abstracts/search?q=rearrangement%20of%20domains" title=" rearrangement of domains"> rearrangement of domains</a> </p> <a href="https://publications.waset.org/abstracts/74890/effect-of-al-contents-on-magnetic-domains-of-100-grains-in-electrical-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74890.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">243</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">8246</span> Nanoindentation Behavior and Physical Properties of Polyvinyl Chloride /Styrene Co-Maleic Anhydride Blend Reinforced by Nano-Bentonite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Elsawy%20Abulyazied">Dalia Elsawy Abulyazied</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Mohamad%20Mokhtar"> Samia Mohamad Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Magdy%20Motawie"> Ahmed Magdy Motawie </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article studies the effects of nano-bentonite on the structure and properties of polymer blends nanocomposites, based on polyvinyl chloride (PVC) and styrene co-maleic anhydride (SMA) blend. Modification of Egyptian bentonite (EB) is carried out using organo-modifier namely; octadecylamine (ODA). Octadecylamine bentonite (ODA-B) is characterized using FTIR, XRD and TEM. Nanocomposites of PVC/SMA/ODA-B are prepared by solution intercalation polymerization from 0.50 up to 5 phr. The nanocomposites are characterized by XRD and TEM. Thermal behavior of the nanocomposites is studied. The effect of different content of ODA-B on the nano-mechanical properties is investigated by a nano-indentation test method. Also the swelling and electrical properties of the nanocomposites are measured. The morphology of the nanocomposites shows that ODA-B achieved good dispersion in the PVC/SMA matrix. The thermal stability of the nanocomposites is enhanced due to the presence of the ODA-B. Incorporation of 0.5, 1, 3 and 5 phr. ODA-B into the PVC/SMA blends results in an improvement in nano-hardness of 16%, 76%, 92%, and 68% respectively. The elastic modulus increased by 37% from 4.59 GPa for unreinforced PVC/SMA blend to 6.30 GPa for 3 phr. The cross-link density and the electrical conductivity of the nanocomposites are increased with increasing the content of ODA-B. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PVC" title="PVC">PVC</a>, <a href="https://publications.waset.org/abstracts/search?q=SMA" title=" SMA"> SMA</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-bentonite" title=" nano-bentonite"> nano-bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title=" nanoindentation"> nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=crosslink%20density" title=" crosslink density"> crosslink density</a> </p> <a href="https://publications.waset.org/abstracts/23611/nanoindentation-behavior-and-physical-properties-of-polyvinyl-chloride-styrene-co-maleic-anhydride-blend-reinforced-by-nano-bentonite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23611.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">8245</span> Induction Machine Bearing Failure Detection Using Advanced Signal Processing Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelghani%20Chahmi">Abdelghani Chahmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article examines the detection and localization of faults in electrical systems, particularly those using asynchronous machines.

Today, using wireless communication for electrical machines is interesting for both real time monitoring and diagnostic purposes. In this paper, we propose a system based on wireless communication IEEE 802.11 to control electrical machine. IEEE 802.11 standard is recommended for this type of applications because it provides a faster connection, better range from the base station, and better security. Therefore, our contribution is to study a new technique to control and monitor the rotating electrical machines (motors, generators) using wireless communication. The reliability of radio channel inside rotating electrical machine is also discussed. Then, the communication protocol, software and hardware design used for the proposed system are presented in detail and the experimental results of our system are illustrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=DFIM%20machine" title=" DFIM machine"> DFIM machine</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=EMC" title=" EMC"> EMC</a>, <a href="https://publications.waset.org/abstracts/search?q=IEEE%20802.11" title=" IEEE 802.11"> IEEE 802.11</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20electrical%20machines" title=" rotating electrical machines"> rotating electrical machines</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20communication" title=" wireless communication"> wireless communication</a> </p> <a href="https://publications.waset.org/abstracts/34526/feasibility-study-of-wireless-communication-for-the-control-and-monitoring-of-rotating-electrical-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34526.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">695</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">8243</span> Designing of Nano-materials for Waste Heat Conversion into Electrical Energy Thermoelectric generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiqar%20Hussain%20Shah">Wiqar Hussain Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The electrical and thermal properties of the doped Tellurium Telluride (Tl10Te6) chalcogenide nano-particles are mainly characterized by a competition between metallic (hole doped concentration) and semi-conducting state. We have studied the effects of Sn doping on the electrical and thermoelectric properties of Tl10-xSnxTe6 (1.00 ≤x≤ 2.00), nano-particles, prepared by solid state reactions in sealed silica tubes and ball milling method. Structurally, all these compounds were found to be phase pure as confirmed by the x-rays diffractometery (XRD) and energy dispersive X-ray spectroscopy (EDS) analysis. Additionally crystal structure data were used to model the data and support the findings. The particles size was calculated from the XRD data by Scherrer’s formula. The EDS was used for an elemental analysis of the sample and declares the percentage of elements present in the system. The thermo-power or Seebeck co-efficient (S) was measured for all these compounds which show that S increases with increasing temperature from 295 to 550 K. The Seebeck coefficient is positive for the whole temperature range, showing p-type semiconductor characteristics. The electrical conductivity was investigated by four probe resistivity techniques revealed that the electrical conductivity decreases with increasing temperature, and also simultaneously with increasing Sn concentration. While for Seebeck coefficient the trend is opposite which is increases with increasing temperature. These increasing behavior of Seebeck coefficient leads to high power factor which are increases with increasing temperature and Sn concentration except For Tl8Sn2Te6 because of lowest electrical conductivity but its power factor increases well with increasing temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sn%20doping%20in%20Tellurium%20Telluride%20nano-materials" title="Sn doping in Tellurium Telluride nano-materials">Sn doping in Tellurium Telluride nano-materials</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20holes%20competition" title=" electron holes competition"> electron holes competition</a>, <a href="https://publications.waset.org/abstracts/search?q=Seebeck%20co-efficient" title=" Seebeck co-efficient"> Seebeck co-efficient</a>, <a href="https://publications.waset.org/abstracts/search?q=effects%20of%20Sn%20doping%20on%20Electrical%20conductivity" title=" effects of Sn doping on Electrical conductivity"> effects of Sn doping on Electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=effects%20on%20Power%20factor" title=" effects on Power factor"> effects on Power factor</a> </p> <a href="https://publications.waset.org/abstracts/163685/designing-of-nano-materials-for-waste-heat-conversion-into-electrical-energy-thermoelectric-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163685.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">44</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">8242</span> Fashion Consumption for Fashion Innovators: A Study of Fashion Consumption Behavior of Innovators and Non-Innovators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaishali%20P.%20Joshi">Vaishali P.

In the past 10 years, a number of energy efficiency initiatives in the residential sector had been undertaken by the government including. However, there is no clear evidence that the total residential energy consumption has been reduced substantially via these strategies. Household electrical appliances such as air conditioners, refrigerators, lighting and televisions are used depending on the consumers’ activities. The behavior of household occupants played an important role in energy consumption and influenced the operation of the physical devices. Therefore, in order to ensure success in energy efficiency program, it requires not only the technological aspect but also the consumers’ behaviors component. This paper focuses on the challenges and opportunities in modelling residential consumer behavior in Malaysia. A field survey to residential consumers was carried out and responses from the survey were analyzed to determine the consumers’ level of knowledge and awareness on energy efficiency. The analyses will be used in determining a right framework to explain household energy use intentions and behavior. These findings will be beneficial to power utility company and energy regulator in addressing energy efficiency related issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20behavior%20theories" title="consumer behavior theories">consumer behavior theories</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20occupants" title=" household occupants"> household occupants</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20consumer" title=" residential consumer"> residential consumer</a> </p> <a href="https://publications.waset.org/abstracts/53418/challenges-and-opportunities-in-modelling-energy-behavior-of-household-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53418.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">333</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">8240</span> Characterization of Chemically Deposited CdS Thin Films Annealed in Different Atmospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Pantoja%20Enr%C3%ADquez">J.

The CdS thin films were annealed in air, argon, hydrogen and nitrogen for 1 h at various temperatures (300, 350, 400, 450 and 500 °C). The changes in optical and electrical properties of annealed treated CdS thin films were analyzed. The results showed that, the band-gap and resistivity depend on the post-deposition annealing atmosphere and temperatures. Thus, it was found that these properties of the films, were found to be affected by various processes with opposite effects, some beneficial and others unfavorable. The energy gap and resistivity for different annealing atmospheres was seen to oscillate by thermal annealing. Recrystallization, oxidation, surface passivation, sublimation and materials evaporation were found the main factors of the heat-treatment process responsible for this oscillating behavior. Annealing over 400 °C was seen to degrade the optical and electrical properties of the film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cds" title="cds">cds</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing" title=" annealing"> annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=optical" title=" optical"> optical</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/31251/characterization-of-chemically-deposited-cds-thin-films-annealed-in-different-atmospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31251.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">510</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">8239</span> The Analysis of Own Signals of PM Electrical Machines – Example of Eccentricity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Baranski">Marcin Baranski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a vibration diagnostic method designed for permanent magnets (PM) traction motors.

In addition, these media can also be used to control the optical properties of the nanoparticles, for instance when they are resonant. In this work, the change on electrical properties of a liquid crystal cell by adding TiO₂ nanoparticles on one of the alignment layers has been analyzed. These nanoparticles, with a diameter of 100 nm and spherical shape, were deposited in one of the substrates (ITO + polyimide) by spin-coating in order to produce a homogeneous layer. These substrates were checked using an optical microscope (objective x100) to avoid potential agglomerates. The liquid crystal cell is then fabricated, using one of these substrates and another without nanoparticles, and filled with E7. The study of the electrical response was done through impedance measurements in a long range of frequencies (3 Hz- 6 MHz) and at ambient temperature. Different nanoparticle concentrations were considered, as well as pure E7 and an empty cell for comparison purposes. Results about the effective dielectric permittivity and conductivity are presented along with models of equivalent electric circuits and its physical interpretation. As a summary, it has been observed the clear influence of the presence of the nanoparticles, strongly modifying the electric response of the device. In particular, a variation of both the effective permittivity and the conductivity of the device have been observed. This result requires a deep analysis of the effect of these nanoparticles on the trapping of free ions in the device, allowing a controlled manipulation and frequency tuning of the electrical response of these devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alignment%20layer" title="alignment layer">alignment layer</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20behavior" title=" electrical behavior"> electrical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20crystal" title=" liquid crystal"> liquid crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO%E2%82%82%20nanoparticles" title=" TiO₂ nanoparticles"> TiO₂ nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/88386/modifying-the-electrical-properties-of-liquid-crystal-cells-by-including-tio2-nanoparticles-on-a-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88386.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">213</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">8237</span> Dynamics Behavior of DFIG Wind Energy Conversion System Incase Dip Voltage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Zerzouri">N.

Growth in size and the optimization of wind turbines has enabled wind energy to become increasingly competitive with conventional energy sources. As a result today’s wind turbines participate actively in the power production of several countries around the world. These developments raise a number of challenges to be dealt with now and in the future. The penetration of wind energy in the grid raises questions about the compatibility of the wind turbine power production with the grid. In particular, the contribution to grid stability, power quality and behavior during fault situations plays therefore as important a role as the reliability. In the present work, we addressed two fault situations that have shown their influence on the generator and the behavior of the wind over the defects which are briefly discussed based on simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20fed%20induction%20generator%20%28DFIG%29" title="doubly fed induction
