Chetioui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Azo dyes are one of the most widely used compounds in organic chemistry, primarily due to their relatively simple preparation methods. They have therefore been widely used, in particular as colorants for textiles, printing inks, cosmetics, and food additives. In addition to their use as dyes, azo compounds have attracted much attention from chemists as their potential applications are important in coordination chemistry, metal-organic frameworks (MOF) structures, COF (covalent-organic frameworks), and catalysis. Moreover, they have found many applications in different fields, such as nonlinear optics, optical storage, photoluminescence, and magnetism. The compound bis{(E)-1-[(2,4,6-tribromophenyl)diazenyl]naphthalen-2-olato}copper(II) dimethyl sulfoxide monosolvate, the CuII atom is tetracoordinate with a square-planar geometry, surrounded by two bidentate (E)-1-[(2,4,6-tribromophenyl)diazenyl]naphthalene-2-olate ligands via two N atoms and two O atoms. The O-Cu-O angles and N-Cu-N are of the order of 177.90(16)° and 177.8(2)°, respectively. The distances Cu-O and Cu- N are 1.892(4) Å and 1.976(4) Å, respectively. The cohesion of the crystal is ensured by hydrogen bonds of the C—H…O type and by π=π staking interactions [centroid–centroid distance = 3.679(4)Å]. The DMSO solvent molecule is disordered at two positions with occupancy rates of 0.70 and 0.30. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=azo%20dyes" title="azo dyes">azo dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=DRX" title=" DRX"> DRX</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20characterization" title=" structural characterization"> structural characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20activity" title=" biological activity"> biological activity</a> </p> <a href="https://publications.waset.org/abstracts/158136/synthesis-structural-characterization-and-biological-activity-of-bise-1-246-tribromophenyl-diazenyl-naphthalen-2-olato-copper-ii-dimethyl-sulfoxide-monosolvate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158136.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">87</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">3</span> Design of Circular Patch Antenna in Terahertz Band for Medical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moulfi%20Bouchra">Moulfi Bouchra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferouani%20Souheyla"> Ferouani Souheyla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziani%20Kerarti%20Djalal"> Ziani Kerarti Djalal</a>, <a href="https://publications.waset.org/abstracts/search?q=Moulessehoul%20Wassila"> Moulessehoul Wassila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wireless body network (WBAN) is the most interesting network these days and especially with the appearance of contagious illnesses such as covid 19, which require surveillance in the house. In this article, we have designed a circular microstrip antenna. Gold is the material used respectively for the patch and the ground plane and Gallium (εr=12.94) is chosen as the dielectric substrate. The dimensions of the antenna are 82.10*62.84 μm2 operating at a frequency of 3.85 THz. The proposed, designed antenna has a return loss of -46.046 dB and a gain of 3.74 dBi, and it can measure various physiological parameters and sensors that help in the overall monitoring of an individual's health condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20patch%20antenna" title="circular patch antenna">circular patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=Terahertz%20transmission" title=" Terahertz transmission"> Terahertz transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=WBAN%20applications" title=" WBAN applications"> WBAN applications</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20monitoring" title=" real-time monitoring"> real-time monitoring</a> </p> <a href="https://publications.waset.org/abstracts/158335/design-of-circular-patch-antenna-in-terahertz-band-for-medical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158335.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">307</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">2</span> A Miniaturized Circular Patch Antenna Based on Metamaterial for WI-FI Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zahra%20Moussa">Fatima Zahra Moussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamina%20Belhadef"> Yamina Belhadef</a>, <a href="https://publications.waset.org/abstracts/search?q=Souheyla%20Ferouani"> Souheyla Ferouani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we present a new form of miniature circular patch antenna based on CSRR metamaterials with an extended bandwidth proposed for 5 GHz Wi-Fiapplications. A reflection coefficient of -35 dB and a radiation pattern of 7.47 dB are obtained when simulating the initial proposed antenna with the CST microwave studio simulation software. The notch insertion technique in the radiating element was used for matching the antenna to the desired frequency in the frequency band [5150-5875] MHz.An extension of the bandwidth from 332 MHz to 1423 MHz was done by the DGS (defected ground structure) technique to meet the user's requirement in the 5 GHz Wi-Fi frequency band. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patch%20antenna" title="patch antenna">patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=miniaturisation" title=" miniaturisation"> miniaturisation</a>, <a href="https://publications.waset.org/abstracts/search?q=CSRR" title=" CSRR"> CSRR</a>, <a href="https://publications.waset.org/abstracts/search?q=notches" title=" notches"> notches</a>, <a href="https://publications.waset.org/abstracts/search?q=wifi" title=" wifi"> wifi</a>, <a href="https://publications.waset.org/abstracts/search?q=DGS" title=" DGS"> DGS</a> </p> <a href="https://publications.waset.org/abstracts/158338/a-miniaturized-circular-patch-antenna-based-on-metamaterial-for-wi-fi-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158338.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">1</span> Decision Making, Reward Processing and Response Selection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benmansour%20Nassima">Benmansour Nassima</a>, <a href="https://publications.waset.org/abstracts/search?q=Benmansour%20Souheyla"> Benmansour Souheyla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The appropriate integration of reward processing and decision making provided by the environment is vital for behavioural success and individuals’ well being in everyday life. Functional neurological investigation has already provided an inclusive image on affective and emotional (motivational) processing in the healthy human brain and has recently focused its interest also on the assessment of brain function in anxious and depressed individuals. This article offers an overview on the theoretical approaches that relate emotion and decision-making, and spotlights investigation with anxious or depressed individuals to reveal how emotions can interfere with decision-making. This research aims at incorporating the emotional structure based on response and stimulation with a Bayesian approach to decision-making in terms of probability and value processing. It seeks to show how studies of individuals with emotional dysfunctions bear out that alterations of decision-making can be considered in terms of altered probability and value subtraction. The utmost objective is to critically determine if the probabilistic representation of belief affords could be a critical approach to scrutinize alterations in probability and value representation in subjective with anxiety and depression, and draw round the general implications of this approach. <p class="card-text"><strong>Keywords:</strong> <a
