We obtained ananalytic expression for the AME field in the RQWIP in the presence of the EMF. The dependence of AME field on the frequency of external acoustic wave, the temperature T of system, the cyclotron frequency of the EMF and the intensity of the EMF is obtained. Theoretical results for the AME field are numerically evaluated, plotted and discussed for a specific RQWIP GaAs/GaAsAl. This result has shown that the dependence of the AME field on intensity of the EMF is nonlinearly and it is many distinct maxima in the quantized magnetic region. We also compared received fields with those for normal bulk semiconductors, quantum well and quantum wire to show the difference. The influence of an EMF on AME field in a RQWIP is newly developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rectangular%20quantum%20wire" title="rectangular quantum wire">rectangular quantum wire</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustomagnetoelectric%20field" title=" acoustomagnetoelectric field"> acoustomagnetoelectric field</a>, <a href="https://publications.waset.org/abstracts/search?q=electron-phonon%20interaction" title=" electron-phonon interaction"> electron-phonon interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic%20equation%20method" title=" kinetic equation method"> kinetic equation method</a> </p> <a href="https://publications.waset.org/abstracts/41446/influence-of-an-external-magnetic-field-on-the-acoustomagnetoelectric-field-in-a-rectangular-quantum-wire-with-an-infinite-potential-by-using-a-quantum-kinetic-equation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41446.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">336</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">12665</span> The Hall Coefficient and Magnetoresistance in Rectangular Quantum Wires with Infinitely High Potential under the Influence of a Laser Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <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> The Hall Coefficient (HC) and the Magnetoresistance (MR) have been studied in two-dimensional systems. The HC and the MR in Rectangular Quantum Wire (RQW) subjected to a crossed DC electric field and magnetic field in the presence of a Strong Electromagnetic Wave (EMW) characterized by electric field are studied in this work. Using the quantum kinetic equation for electrons interacting with optical phonons, we obtain the analytic expressions for the HC and the MR with a dependence on magnetic field, EMW frequency, temperatures of systems and the length characteristic parameters of RQW. These expressions are different from those obtained for bulk semiconductors and cylindrical quantum wires. The analytical results are applied to GaAs/GaAs/Al. For this material, MR depends on the ratio of the EMW frequency to the cyclotron frequency. Indeed, MR reaches a minimum at the ratio 5/4, and when this ratio increases, it tends towards a saturation value. The HC can take negative or positive values. Each curve has one maximum and one minimum. When magnetic field increases, the HC is negative, achieves a minimum value and then increases suddenly to a maximum with a positive value. This phenomenon differs from the one observed in cylindrical quantum wire, which does not have maximum and minimum values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hall%20coefficient" title="hall coefficient">hall coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20quantum%20wires" title=" rectangular quantum wires"> rectangular quantum wires</a>, <a href="https://publications.waset.org/abstracts/search?q=electron-optical%20phonon%20interaction" title=" electron-optical phonon interaction"> electron-optical phonon interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20kinetic%20equation" title=" quantum kinetic equation"> quantum kinetic equation</a> </p> <a href="https://publications.waset.org/abstracts/41442/the-hall-coefficient-and-magnetoresistance-in-rectangular-quantum-wires-with-infinitely-high-potential-under-the-influence-of-a-laser-radiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41442.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">488</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">12664</span> Effect of Control Lasers Polarization on Absorption Coefficient and Refractive Index of a W-Type 4- Level Cylindrical Quantum Dot in the Presence Of Electromagnetically Induced Transparency (ETI)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marziehossadat%20Moezzi">Marziehossadat Moezzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, electromagnetically induced transparency (EIT) is investigated in a cylindrical quantum dot (QD) with a parabolic confinement potential.

Abdikian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A quantum breathing mode has been theatrically studied in quantum dusty plasma. By using linear quantum hydrodynamic model, not only the quantum dispersion relation of rotation mode but also void structure has been derived in the presence of an external magnetic field. Although the phase velocity of the magnetized quantum breathing mode is greater than that of unmagnetized quantum breathing mode, attenuation of the magnetized quantum breathing mode along radial distance seems to be slower than that of unmagnetized quantum breathing mode. Clearly, drawing the quantum breathing mode in the presence and absence of a magnetic field, we found that the magnetic field alters the distribution of dust particles and changes the radial and azimuthal velocities around the axis. Because the magnetic field rotates the dust particles and collects them, it could compensate the void structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20linear%20quantum%20hydrodynamic%20model" title="the linear quantum hydrodynamic model">the linear quantum hydrodynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20magnetized%20quantum%20breathing%20mode" title=" the magnetized quantum breathing mode"> the magnetized quantum breathing mode</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20quantum%20dispersion%20relation%20of%20rotation%20mode" title=" the quantum dispersion relation of rotation mode"> the quantum dispersion relation of rotation mode</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20structure" title=" void structure"> void structure</a> </p> <a href="https://publications.waset.org/abstracts/69938/the-magnetized-quantum-breathing-in-cylindrical-dusty-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69938.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">12660</span> Acoustic Radiation from an Infinite Cylindrical Shell with Periodic Lengthwise Ribs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunzhe%20Tong">Yunzhe Tong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Fan"> Jun Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Wang"> Bin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The vibroacoustic behavior of an immersed infinite cylindrical shell with periodic lengthwise ribs has been studied in this paper. The motions of the shell are described by the Donnell equations. Each lengthwise rib is modeled as an elastic beam. The motions of the bulkheads are decomposed into the longitudinal motions and flexural motions. The analytical expressions of the shell motions can be obtained through circumferential mode expansion, Fourier Transform and periodic boundary condition in the circumferential direction. Furthermore, the far-field radiated pressure has been obtained using the stationary phase. The analysis of wavenumber domain shows that periodic lengthwise stiffeners in the circumferential direction can produce flexural Bloch waves. The dominant feature in far-field pressure amplitude is the resonance of the supersonic components of the flexural Bloch waves in the circumferential direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexural%20Bloch%20wave" title="flexural Bloch wave">flexural Bloch wave</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffened%20shell" title=" stiffened shell"> stiffened shell</a>, <a href="https://publications.waset.org/abstracts/search?q=vibroacoustics" title=" vibroacoustics"> vibroacoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=wavenumber%20analysis" title=" wavenumber analysis"> wavenumber analysis</a> </p> <a href="https://publications.waset.org/abstracts/90699/acoustic-radiation-from-an-infinite-cylindrical-shell-with-periodic-lengthwise-ribs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90699.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">209</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">12659</span> Quantum Algebra from Generalized Q-Algebra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muna%20Tabuni">Muna Tabuni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper contains an investigation of the notion of Q algebras. A brief introduction to quantum mechanics is given, in that systems the state defined by a vector in a complex vector space H which have Hermitian inner product property.

The coaxially fed microstrip antenna configurations with circular patch are analyzed by using the in-house 3DTLMcyl_cw solver based on computational electromagnetic TLM method adapted to the cylindrical grid and enhanced with the compact wire model. Opposed to the widely used rectangular TLM mesh, where a staircase approximation has to be used to describe curved boundaries, precise modelling of circular boundaries can be accomplished in the cylindrical grid irrespective of the mesh resolution. Using the compact wire model incorporated in cylindrical mesh, it is possible to model coaxial feed and include the influence of the real excitation in the antenna model. The conventional and inverted configuration of a coaxially fed circular patch antenna are considered, comparing the resonances obtained using TLM cylindrical model with results reached by the corresponding model in a rectangular grid as well as with experimental ones. Bearing in mind that accuracy of simulated results depends on a relevantly created model, besides structure geometry and dimensions, it is important to consider additional modelling issues, regarding appropriate mesh resolution and a relevant extension of a mesh around the considered structure that would provide convergence of the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20electromagnetic" title="computational electromagnetic">computational electromagnetic</a>, <a href="https://publications.waset.org/abstracts/search?q=coaxial%20feed" title=" coaxial feed"> coaxial feed</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20antenna" title=" microstrip antenna"> microstrip antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=TLM%20modelling" title=" TLM modelling"> TLM modelling</a> </p> <a href="https://publications.waset.org/abstracts/50589/transmission-line-matrix-tlm-modelling-of-microstrip-circular-antenna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50589.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">280</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">12657</span> Annealing Process Study at Galvanizing Line: Characterization and Implication Inherent to Lead Entrainment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20Franzkowiak%20Stahlschmidt">Marcelo Franzkowiak Stahlschmidt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the experiments carried out based on the wire drawing process analysis and later annealing on lead furnace on a galvanizing line.

Einstein's path, which is mainly based on particle mechanics, and the path of Paul Dirac and others, which is based on wave mechanics, the incompatibility of the two approaches is due to the radical difference in the initial assumptions and the mathematical nature of each approach. Logical thinking in modern physics leads us to two problems: - In quantum mechanics, despite its success, the problem of measurement and the problem of wave function interpretation is still obscure. - In special relativity, despite the success of the equivalence of rest-mass and energy, but at the speed of light, the fact that the energy becomes infinite is contrary to logic because the speed of light is not infinite, and the mass of the particle is not infinite too. These contradictions arise from the overlap of relativistic and quantum mechanics in the neighborhood of the speed of light, and in order to solve these problems, one must understand well how to move from relativistic mechanics to quantum mechanics, or rather, to unify them in a way different from Dirac's method, in order to go along with God or Nature, since, as Einstein said, "God doesn't play dice." From De Broglie's hypothesis about wave-particle duality, Léon Brillouin's definition of the new proper time was deduced, and thus the quantum Lorentz factor was obtained. Finally, using the Euler-Lagrange equation, we come up with new equations in quantum mechanics. In this paper, the two problems in modern physics mentioned above are solved; it can be said that this new approach to quantum mechanics will enable us to unify it with general relativity quite simply. If the experiments prove the validity of the results of this research, we will be able in the future to transport the matter at speed close to the speed of light. Finally, this research yielded three important results: 1- Lorentz quantum factor. 2- Planck energy is a limited case of Einstein energy. 3- Real quantum mechanics, in which new equations for quantum mechanics match and exceed Dirac's equations, these equations have been reached in a completely different way from Dirac's method. These equations show that quantum mechanics is a limited case of relativistic mechanics. At the Solvay Conference in 1927, the debate about quantum mechanics between Bohr, Einstein, and others reached its climax, while Bohr suggested that if particles are not observed, they are in a probabilistic state, then Einstein said his famous claim ("God does not play dice"). Thus, Einstein was right, especially when he didn't accept the principle of indeterminacy in quantum theory, although experiments support quantum mechanics. However, the results of our research indicate that God really does not play dice; when the electron disappears, it turns into amicable particles or an elastic medium, according to the above obvious equations. Likewise, Bohr was right also, when he indicated that there must be a science like quantum mechanics to monitor and study the motion of subatomic particles, but the picture in front of him was blurry and not clear, so he resorted to the probabilistic interpretation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lorentz%20quantum%20factor" title="lorentz quantum factor">lorentz quantum factor</a>, <a href="https://publications.waset.org/abstracts/search?q=new" title=" new"> new</a>, <a href="https://publications.waset.org/abstracts/search?q=planck%E2%80%99s%20energy%20as%20a%20limiting%20case%20of%20einstein%E2%80%99s%20energy" title=" planck’s energy as a limiting case of einstein’s energy"> planck’s energy as a limiting case of einstein’s energy</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20quantum%20mechanics" title=" real quantum mechanics"> real quantum mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20equations%20for%20quantum%20mechanics" title=" new equations for quantum mechanics"> new equations for quantum mechanics</a> </p> <a href="https://publications.waset.org/abstracts/159579/quantum-mechanics-as-a-limiting-case-of-relativistic-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159579.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">77</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">12655</span> Introducing Quantum-Weijsberg Algebras by Redefining Quantum-MV Algebras: Characterization, Properties, and Other Important Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lavinia%20Ciungu">Lavinia Ciungu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decades, developing algebras related to the logical foundations of quantum mechanics became a central topic of research. Generally known as quantum structures, these algebras serve as models for the formalism of quantum mechanics. In this work, we introduce the notion of quantum-Wajsberg algebras by redefining the quantum-MV algebras starting from involutive BE algebras. We give a characterization of quantum-Wajsberg algebras, investigate their properties, and show that, in general, quantum-Wajsberg algebras are not (commutative) quantum-B algebras. We also define the ∨-commutative quantum-Wajsberg algebras and study their properties. Furthermore, we prove that any Wajsberg algebra (bounded ∨-commutative BCK algebra) is a quantum-Wajsberg algebra, and we give a condition for a quantum-Wajsberg algebra to be a Wajsberg algebra. We prove that Wajsberg algebras are both quantum-Wajsberg algebras and commutative quantum-B algebras. We establish the connection between quantum-Wajsberg algebras and quantum-MV algebras, proving that the quantum-Wajsberg algebras are term equivalent to quantum-MV algebras. We show that, in general, the quantum-Wajsberg algebras are not commutative quantum-B algebras and if a quantum-Wajsberg algebra is self-distributive, then the corresponding quantum-MV algebra is an MV algebra. Our study could be a starting point for the development of other implicative counterparts of certain existing algebraic quantum structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quantum-Wajsberg%20algebra" title="quantum-Wajsberg algebra">quantum-Wajsberg algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum-MV%20algebra" title=" quantum-MV algebra"> quantum-MV algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=MV%20algebra" title=" MV algebra"> MV algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=Wajsberg%20algebra" title=" Wajsberg algebra"> Wajsberg algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=BE%20algebra" title=" BE algebra"> BE algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum-B%20algebra" title=" quantum-B algebra"> quantum-B algebra</a> </p> <a href="https://publications.waset.org/abstracts/192449/introducing-quantum-weijsberg-algebras-by-redefining-quantum-mv-algebras-characterization-properties-and-other-important-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192449.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">15</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">12654</span> Bending Test Characteristics for Splicing of Thermoplastic Polymer Using Hot Gas Welding </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prantasi%20Harmi%20%20Tjahjanti">Prantasi Harmi Tjahjanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Iswanto%20Iswanto"> Iswanto Iswanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Edi%20%20Widodo"> Edi Widodo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sholeh%20%20Pamuji"> Sholeh Pamuji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Materials of the thermoplastic polymer when they break is usually thrown away, or is recycled which requires a long process.

Quantum algorithms have the potential to execute substantially faster than their classical equivalents, which can lead to significant improvements in computational performance and efficiency.

In contrast to classical cryptographic schemes, the security of QC schemes is guaranteed by the fundamental laws of nature. Their security stems from the impossibility to distinguish non-orthogonal quantum states with certainty. A potential eavesdropper introduces errors in the transmissions, which can later be discovered by the legitimate participants of the communication. In this paper, the modeling approach is proposed for QC protocol BB84 using polarization coding. The single-photon system is assumed to be used in the designed models. Thus, Eve cannot use beam-splitting strategy to eavesdrop on the quantum channel transmission. The only eavesdropping strategy possible to Eve is the intercept/resend strategy. After quantum transmission of the QC protocol, the quantum bit error rate (QBER) is estimated and compared with a threshold value. If it is above this value the procedure must be stopped and performed later again. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security" title="security">security</a>, <a href="https://publications.waset.org/abstracts/search?q=key%20distribution" title=" key distribution"> key distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptography" title=" cryptography"> cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20protocols" title=" quantum protocols"> quantum protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=Quantum%20Cryptography%20%28QC%29" title=" Quantum Cryptography (QC)"> Quantum Cryptography (QC)</a>, <a href="https://publications.waset.org/abstracts/search?q=Quantum%20Key%20Distribution%20%28QKD%29." title=" Quantum Key Distribution (QKD)."> Quantum Key Distribution (QKD).</a> </p> <a href="https://publications.waset.org/abstracts/2413/secure-optical-communication-system-using-quantum-cryptography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2413.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">406</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">12648</span> Joining of Aluminum and Steel in Car Body Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Mohammadi">Mohammad Mahdi Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zinc-coated steel sheets have been joined with aluminum samples in an overlapping as well as in a butt-joint configuration.

To show this phenomenon, the temperature rise of a hot wire, immersed in DIW and Ferrofluid, as a result of joule heating has been measured using a transient hot-wire technique. When current is applied to the wire, a temperature gradient is imposed on the magnetic fluid resulting in non-uniform magnetic susceptibility of the ferrofluid that results in a non-uniform magnetic body force which makes the ferrofluid flow as a bulk suspension. For the case of the wire immersed in DIW, free convection is the only means of cooling, while for the case of ferrofluid a combination of both free convection and thermomagnetic convection is expected to enhance the heat transfer from the wire beyond that of DIW. Experimental results at different temperatures and for a range of constant currents applied to the wire show that thermomagnetic convection becomes effective for the currents higher than 1.5A at all temperatures. It is observed that the onset of thermomagnetic convection is directly proportional to the current applied to the wire and that the thermomagnetic convection happens much faster than the free convection. Calculations show that a 35% enhancement in heat transfer can be expected for the ferrofluid compared to DIW, for a 3A current applied to the wire. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooling" title="cooling">cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrofluid" title=" ferrofluid"> ferrofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=thermomagnetic%20convection" title=" thermomagnetic convection"> thermomagnetic convection</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a> </p> <a href="https://publications.waset.org/abstracts/62634/thermomagnetic-convection-of-a-ferrofluid-in-a-non-uniform-magnetic-field-induced-a-current-carrying-wire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62634.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">263</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">12646</span> CdS Quantum Dots as Fluorescent Probes for Detection of Naphthalene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhengyu%20Yan">Zhengyu Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Yu"> Yan Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianqiu%20Chen"> Jianqiu Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel sensing system has been designed for naphthalene detection based on the quenched fluorescence signal of CdS quantum dots.

It is because the expression of the HC for the confined phonon case contains indexes m, m’ which are specific to the phonon confinement. The expression in a RQW is different from that for the case of unconfined phonons in a RQW or in 2D. The results are numerically calculated and discussed for a GaAs/GaAsAl RQW. The numerical results show that HC in a RQW can have both negative and positive values. This is different from the case of the absence of EMW and the case presence of EMW including the effect of phonon unconfinement in a RQW. These results are also compared with those in the case of unconfined phonons in a RQW and confined phonons in a quantum well. The conductivity in the case of confined phonon has more resonance peaks compared with that in case of unconfined phonons in a RQW. This new property is the same in quantum well.

Wire localization remains the method of choice in non-palpable breast cancers post-neoadjuvant chemotherapy. Objective: The aim of our study was to determine the accuracy of wire localization procedures in our department and compare it with internationally set protocols as per the Royal College of Radiologists. Post wire mammography, as well as the margin status of the postoperative specimen, assessed the accuracy of the procedure. Methods: We retrospectively reviewed the data of 225 patients who presented to our department from May 2014 to June 2015 post neoadjuvant chemotherapy with non-palpable cancers. These patients are candidates for wire localized lumpectomies either under ultrasound or stereotactic guidance. Metallic marker was placed in all the patients at the time of biopsy. Post wire mammogram was performed in all the patients and the distance of the wire tip from the marker was calculated. The presence or absence of the metallic clip in the postoperative specimen, as well as the marginal status of the postoperative specimen, was noted. Results: 157 sonographic and 68 stereotactic wire localization procedures were performed. 95% of the wire tips were within 1 cm of the metallic marker. Marginal status was negative in 94% of the patients in histopathological specimen. Conclusion: Our audit report declares more than 95% accuracy of image guided wire localization in successful excision of non-palpable breast lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast" title="breast">breast</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=non-palpable" title=" non-palpable"> non-palpable</a>, <a href="https://publications.waset.org/abstracts/search?q=wire%20localization" title=" wire localization"> wire localization</a> </p> <a href="https://publications.waset.org/abstracts/49198/wire-localization-procedures-in-non-palpable-breast-cancers-an-audit-report-and-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49198.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">311</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">12640</span> Theoretical Density Study of Winding Yarns on Spool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Chemani">Bachir Chemani</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Halfaoui"> Rachid Halfaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of work is to define the distribution density of winding yarn on cylindrical and conical bobbins.

The variation of specific density over the reel height is explained generally by the sudden change of winding speed due to direction movement variation of yarn. We determined the conditions of uniform winding and developed a calculate model to the change of the specific density of winding wire over entire spool height. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=textile" title="textile">textile</a>, <a href="https://publications.waset.org/abstracts/search?q=cylindrical%20bobbins" title=" cylindrical bobbins"> cylindrical bobbins</a>, <a href="https://publications.waset.org/abstracts/search?q=conical%20bobbins" title=" conical bobbins"> conical bobbins</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20winding" title=" parallel winding"> parallel winding</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20winding" title=" cross winding"> cross winding</a> </p> <a href="https://publications.waset.org/abstracts/16154/theoretical-density-study-of-winding-yarns-on-spool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16154.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">377</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">12639</span> Generalized Hyperbolic Functions: Exponential-Type Quantum Interactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Juan%20Pe%C3%B1a">Jose Juan Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Morales"> J.

In order to transcend the scope of hyperbolic functions, in this work, a kind of generalized q-deformed hyperbolic functions (g q-dhf) is presented. By a suitable transformation, through the q deformation parameter, it is shown that these g q-dhf can be expressed in terms of their corresponding standard ones besides they can be reduced to the sc q-dhf. As a useful application of the proposed approach, and considering a class of exactly solvable multi-parameter exponential-type potentials, some new q-deformed quantum interactions models that can be used as interesting alternative in quantum physics and quantum states are presented. Furthermore, due that quantum potential models are conditioned on the q-dependence of the parameters that characterize to the exponential-type potentials, it is shown that many specific cases of q-deformed potentials are obtained as particular cases from the proposal. <p class="card-text"><strong>Keywords:</strong> <a
