</p> <p class="card-text"><strong>Abstract:</strong></p> The analysis of how vibrations are transmitted between components is required in many engineering applications. Transfer path analysis (TPA) has been a valuable engineering tool for solving Noise, Vibration, and Harshness (NVH problems using sub-structuring applications. The most challenging part of a TPA analysis is estimating the equivalent forces at the contact points between the active and the passive side. Component TPA in situ Method calculates these forces by inverting the frequency response functions (FRFs) measured at the passive subsystem, relating the motion at indicator points to forces at the interface. However, matrix inversion could pose problems due to the ill-conditioning of the matrices leading to inaccurate results. This paper establishes a TPA model for an academic system consisting of two plates linked by four springs. A numerical study has been performed to improve the interface forces identification. Several parameters are studied and discussed, such as the singular value rejection and the number and position of indicator points chosen and used in the inversion matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transfer%20path%20analysis" title="transfer path analysis">transfer path analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20inverse%20method" title=" matrix inverse method"> matrix inverse method</a>, <a href="https://publications.waset.org/abstracts/search?q=indicator%20points" title=" indicator points"> indicator points</a>, <a href="https://publications.waset.org/abstracts/search?q=SVD%20decomposition" title=" SVD decomposition"> SVD decomposition</a> </p> <a href="https://publications.waset.org/abstracts/166401/enhancing-transfer-path-analysis-with-in-situ-component-transfer-path-analysis-for-interface-forces-identification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166401.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">84</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">16</span> Mechanical Study Material on Low Environmental Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fetta%20Ait%20Ahsene-Aissat">Fetta Ait Ahsene-Aissat</a>, <a href="https://publications.waset.org/abstracts/search?q=Messaoud%20Hachemi"> Messaoud Hachemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Moussaoui"> Yacine Moussaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Kerchiche"> Yacine Kerchiche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our study focuses on two important aspects, environmental by using a sub industrial product (FAD), by economic incorporation as an addition to Portland cement, thus improving resistance to compression and bending with different proportions ADF % up to 40 additions.

However, the performance of the anode material in LIBs is crucial for enhancing the battery's overall efficiency. This research focuses on developing a new anode material by modifying silicon nanostructures, specifically porous silicon nanowires (PSiNWs) and porous silicon nanoparticles (NPSiP), with silver nanoparticles (Ag) to improve the performance of LIBs. The aim of this research is to investigate the potential application of PSiNWs/Ag and NPSiP/Ag as anodes in LIBs and evaluate their performance in terms of specific capacity and Coulombic efficiency. The research methodology involves the preparation of PSiNWs and NPSiP using metal-assisted chemical etching and electrochemical etching techniques, respectively. The Ag nanoparticles are introduced onto the nanostructures through electrodissolution of the porous film and ultrasonic treatment. Galvanostatic charge/discharge measurements are conducted between 1 and 0.01 V to evaluate the specific capacity and Coulombic efficiency of both PSiNWs/Ag and NPSiP/Ag electrodes. The specific capacity of the PSiNWs/Ag electrode is approximately 1800 mA h g-1, with a Coulombic efficiency of 98.8% at the first charge/discharge cycle. On the other hand, the NPSiP/Ag electrode exhibits a specific capacity of 2600 mAh g-1. Both electrodes show a slight increase in capacity retention after 80 cycles, attributed to the high porosity and surface area of the nanostructures and the stabilization of the solid electrolyte interphase (SEI). This research highlights the potential of using modified silicon nanostructures as anodes for LIBs, which can pave the way for the development of more efficient lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=porous%20silicon%20nanowires" title="porous silicon nanowires">porous silicon nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20nanoparticles" title=" silicon nanoparticles"> silicon nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title=" lithium-ion batteries"> lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanostatic%20charge%2Fdischarge" title=" galvanostatic charge/discharge"> galvanostatic charge/discharge</a> </p> <a href="https://publications.waset.org/abstracts/171753/an-anode-based-on-modified-silicon-nanostructured-for-lithium-ion-battery-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171753.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">63</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">11</span> Selecting Skyline Mash-Ups under Uncertainty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aymen%20Gammoudi">Aymen Gammoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Labbaci"> Hamza Labbaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Nizar%20Messai"> Nizar Messai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Sam"> Yacine Sam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Web Service Composition (Mash-up) has been considered as a new approach used to offer the user a set of Web Services responding to his request. These approaches can return a set of similar Mash-ups in a given context that makes users unable to select the perfect one. Recent approaches focus on computing the skyline over a set of Quality of Service (QoS) attributes. However, these approaches are not sufficient in a dynamic web service environment where the delivered QoS by a Web service is inherently uncertain. In this paper, we treat the problem of computing the skyline over a set of similar Mash-ups under certain dimension values. We generate dimensions for each Mash-up using aggregation operations applied to the QoS attributes. We then tackle the problem of computing the skyline under uncertain dimensions. We present each dimension value of mash-up using a frame of discernment and introduce the d-dominance using the Evidence Theory. Finally, we propose our experimental results that show both the effectiveness of the introduced skyline extensions and the efficiency of the proposed approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web%20services" title="web services">web services</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertain%20QoS" title=" uncertain QoS"> uncertain QoS</a>, <a href="https://publications.waset.org/abstracts/search?q=mash-ups" title=" mash-ups"> mash-ups</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertain%20%20dimensions" title=" uncertain dimensions"> uncertain dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=skyline" title=" skyline"> skyline</a>, <a href="https://publications.waset.org/abstracts/search?q=evidence%20%20theory" title=" evidence theory"> evidence theory</a>, <a href="https://publications.waset.org/abstracts/search?q=d-dominance" title=" d-dominance"> d-dominance</a> </p> <a href="https://publications.waset.org/abstracts/137195/selecting-skyline-mash-ups-under-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137195.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">234</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">10</span> Long Short-Term Memory Based Model for Modeling Nicotine Consumption Using an Electronic Cigarette and Internet of Things Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdi%20Amroun">Hamdi Amroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Benziani"> Yacine Benziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ammi"> Mehdi Ammi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we want to determine whether the accurate prediction of nicotine concentration can be obtained by using a network of smart objects and an e-cigarette. The approach consists of, first, the recognition of factors influencing smoking cessation such as physical activity recognition and participant’s behaviors (using both smartphone and smartwatch), then the prediction of the configuration of the e-cigarette (in terms of nicotine concentration, power, and resistance of e-cigarette). The study uses a network of commonly connected objects; a smartwatch, a smartphone, and an e-cigarette transported by the participants during an uncontrolled experiment. The data obtained from sensors carried in the three devices were trained by a Long short-term memory algorithm (LSTM). Results show that our LSTM-based model allows predicting the configuration of the e-cigarette in terms of nicotine concentration, power, and resistance with a root mean square error percentage of 12.9%, 9.15%, and 11.84%, respectively. This study can help to better control consumption of nicotine and offer an intelligent configuration of the e-cigarette to users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iot" title="Iot">Iot</a>, <a href="https://publications.waset.org/abstracts/search?q=activity%20recognition" title=" activity recognition"> activity recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20classification" title=" automatic classification"> automatic classification</a>, <a href="https://publications.waset.org/abstracts/search?q=unconstrained%20environment" title=" unconstrained environment"> unconstrained environment</a> </p> <a href="https://publications.waset.org/abstracts/89965/long-short-term-memory-based-model-for-modeling-nicotine-consumption-using-an-electronic-cigarette-and-internet-of-things-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89965.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">224</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">9</span> Temporal Trends in the Urban Metabolism of Riyadh, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naif%20Albelwi">Naif Albelwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Kwan"> Alan Kwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Rezgui"> Yacine Rezgui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cities with rapid growth face tremendous challenges not only to provide services to meet this growth but also to assure that this growth occurs in a sustainable way. The consumption of material, energy, and water resources is inextricably linked to population growth with a unique impact in urban areas, especially in light of significant investments in infrastructure to support urban development. Urban Metabolism (UM) is becoming popular as it provides a framework accounting the mass and energy flows through a city. The objective of this study is to determine the energy and material flows of Riyadh, Saudi Arabia using locally generated data from 1996 and 2012 and analyzing the temporal trends of energy and material flows. Preliminary results show that while the population of Riyadh grew 90% since 1996, the input and output flows have increased at higher rate. Results also show increasing in energy mobile consumption from 61k TJ in 1996 to 157k TJ in 2012 which points to Riyadh’s inefficient urban form. The study findings highlight the importance to develop effective policies for improving the use of resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20and%20water%20consumption" title="energy and water consumption">energy and water consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20development" title=" urban development"> urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20metabolism" title=" urban metabolism"> urban metabolism</a> </p> <a href="https://publications.waset.org/abstracts/55550/temporal-trends-in-the-urban-metabolism-of-riyadh-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55550.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">272</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">8</span> Thermal Interruption Performance of High Voltage Gas Circuit Breaker Operating with CO₂ Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Babou">Yacine Babou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitesh%20Ranjan"> Nitesh Ranjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Branimir%20Radisavljevic"> Branimir Radisavljevic </a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Seeger"> Martin Seeger</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Over"> Daniel Over</a>, <a href="https://publications.waset.org/abstracts/search?q=Torsten%20Votteler"> Torsten Votteler</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Galletti"> Bernardo Galletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Cristini"> Paulo Cristini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the frame of replacement of Sulfur hexafluoride (SF6) gas as insulating and switching medium, diverse alternative gases, offering acceptable Global Warming Potential and fulfilling requirements in terms of heat dissipation, insulation and arc quenching performances are currently investigated for High Voltage Circuit Breaker applications. Among the potential gases, CO₂ seems a promising candidate for replacing SF6, because on one hand it is environmentally friendly, harmless, non-toxic, non-corrosive, non-flammable and on the other hand previous studies have demonstrated its fair interruption capabilities. The present study aims at investigating the performance of CO₂ for the thermal interruption in high voltage self-blast circuit breakers. In particular, the correlation between thermal interruption performance and arc voltage is considered and the effect of the arc-network interaction on the performance is rigorously analyzed. For the considered designs, the thermal interruption was evaluated by varying the slope at current zero (i.e., di/dt) for which the breaker could interrupt. Besides, the characteristics of the post-arc current are examined in detail for various rated voltages and currents. The outcome of these experimental investigations will be reported and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=current%20zero%20measurement" title="current zero measurement">current zero measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20circuit%20breaker" title=" high voltage circuit breaker"> high voltage circuit breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20arc%20discharge" title=" thermal arc discharge"> thermal arc discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20interruption" title=" thermal interruption"> thermal interruption</a> </p> <a href="https://publications.waset.org/abstracts/135199/thermal-interruption-performance-of-high-voltage-gas-circuit-breaker-operating-with-co2-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135199.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">185</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">7</span> Liquid-Liquid Extraction of Uranium (VI) from Aqueous Solution Using 1-Hydroxyalkylidene-1,1-Diphosphonic Acids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Bouhoun%20Ali">Mustapha Bouhoun Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Yacine%20Badjah%20Hadj%20Ahmed"> Ahmed Yacine Badjah Hadj Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouloud%20Attou"> Mouloud Attou</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Hamid%20Elias"> Abdel Hamid Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Didi"> Mohamed Amine Didi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extraction of uranium(VI) from aqueous solutions has been investigated using 1-hydroxyhexadecylidene-1,1-diphosphonic acid (HHDPA) and 1-hydroxydodecylidene-1,1-diphosphonic acid (HDDPA), which were synthesized and characterized by elemental analysis and by FT-IR, 1H NMR, 31P NMR spectroscopy. In this paper, we propose a tentative assignment for the shifts of those two ligands and their specific complexes with uranium(VI). We carried out the extraction of uranium(VI) by HHDPA and HDDPA from [carbon tetrachloride + 2-octanol (v/v: 90%/10%)] solutions. Various factors such as contact time, pH, organic/aqueous phase ratio and extractant concentration were considered. The optimum conditions obtained were: contact time = 20 min, organic/aqueous phase ratio = 1, pH value = 3.0 and extractant concentration = 0.3M. The extraction yields are more significant in the case of the HHDPA which is equipped with a hydrocarbon chain, longer than that of the HDDPA. Logarithmic plots of the uranium(VI) distribution ratio vs. pHeq and the extractant concentration showed that the ratio of extractant to extracted uranium(VI) (ligand/metal) is 2:1. The formula of the complex of uranium(VI) with the HHDPA and the DHDPA is UO2(H3L)2 (HHDPA and DHDPA are denoted as H4L). A spectroscopic analysis has showed that coordination of uranium(VI) takes place via oxygen atoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20extraction" title="liquid-liquid extraction">liquid-liquid extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium%28VI%29" title=" uranium(VI)"> uranium(VI)</a>, <a href="https://publications.waset.org/abstracts/search?q=1-hydroxyalkylidene-1" title=" 1-hydroxyalkylidene-1"> 1-hydroxyalkylidene-1</a>, <a href="https://publications.waset.org/abstracts/search?q=1-diphosphonic%20acids" title="1-diphosphonic acids">1-diphosphonic acids</a>, <a href="https://publications.waset.org/abstracts/search?q=HHDPA" title=" HHDPA"> HHDPA</a>, <a href="https://publications.waset.org/abstracts/search?q=HDDPA" title=" HDDPA"> HDDPA</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/18650/liquid-liquid-extraction-of-uranium-vi-from-aqueous-solution-using-1-hydroxyalkylidene-11-diphosphonic-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18650.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">528</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">6</span> Statistical Analysis Approach for the e-Glassy Mortar And Radiation Shielding Behaviors Using Anova</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abadou%20Yacine">Abadou Yacine</a>, <a href="https://publications.waset.org/abstracts/search?q=Faid%20Hayette"> Faid Hayette</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Significant investigations were performed on the use and impact on physical properties along with the mechanical strength of the recycled and reused E-glass waste powder. However, it has been modelled how recycled display e-waste glass may affect the characteristics and qualities of dune sand mortar. To be involved in this field, an investigation has been done with the substitution of dune sand for recycled E-glass waste and constant water-cement ratios. The linear relationship between the dune sand mortar and E-glass mortar mix % contributes to the model's reliability. The experimental data was exposed to regression analysis using JMP Statistics software. The regression model with one predictor presented the general form of the equation for the prediction of the five properties' characteristics of dune sand mortar from the substitution ratio of E-waste glass and curing age. The results illustrate that curing a long-term process produced an E-glass waste mortar specimen with the highest compressive strength of 68 MPa in the laboratory environment. Anova analysis indicated that the curing at long-term has the utmost importance on the sorptivity level and ultrasonic pulse velocity loss. Furthermore, the E-glass waste powder percentage has the utmost importance on the compressive strength and improvement in dynamic elasticity modulus.

The experiment we propose is based on the use of three types of connected objects (smartphone, smart watch, and a connected remote control). 23 participants were observed while watching their TV programs during three phases: before, during and after watching a TV program. Their behaviors were detected using an approach based on The Dempster Shafer Theory (DST) in two phases. The first phase is to approximate dynamically the mass functions using an approach based on the correlation coefficient. The second phase is to calculate the approximate mass functions. To approximate the mass functions, two approaches have been tested: the first approach was to divide each features data space into cells; each one has a specific probability distribution over the behaviors. The probability distributions were computed statistically (estimated by empirical distribution). The second approach was to predict the TV-viewing behaviors through the use of classifiers algorithms and add uncertainty to the prediction based on the uncertainty of the model. Results showed that mixing the fusion rule with the computation of the initial approximate mass functions using a classifier led to an overall of 96%, 95% and 96% success rate for the first, second and third TV-viewing phase respectively. The results were also compared to those found in the literature. This study aims to anticipate certain actions in order to maintain the attention of TV viewers towards the proposed TV programs with usual connected objects, taking into account the various uncertainties that can be generated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iot" title="Iot">Iot</a>, <a href="https://publications.waset.org/abstracts/search?q=TV-viewing%20behaviors%20identification" title=" TV-viewing behaviors identification"> TV-viewing behaviors identification</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20classification" title=" automatic classification"> automatic classification</a>, <a href="https://publications.waset.org/abstracts/search?q=unconstrained%20environment" title=" unconstrained environment"> unconstrained environment</a> </p> <a href="https://publications.waset.org/abstracts/89964/a-framework-based-on-dempster-shafer-theory-of-evidence-algorithm-for-the-analysis-of-the-tv-viewers-behaviors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89964.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">229</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">4</span> Sudden Death and Chronic Disseminated Intravascular Coagulation (DIC): Two Case Reports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saker%20Lilia">Saker Lilia</a>, <a href="https://publications.waset.org/abstracts/search?q=Youcef%20Mellouki"> Youcef Mellouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakhdar%20Sellami"> Lakhdar Sellami</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Zerairia"> Yacine Zerairia</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhaid%20Zetili"> Abdelhaid Zetili</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Guahria"> Fatma Guahria</a>, <a href="https://publications.waset.org/abstracts/search?q=Fateh%20Kaious"> Fateh Kaious</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesrine%20Belkhodja"> Nesrine Belkhodja</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhamid%20Mira"> Abdelhamid Mira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sudden death is regarded as a suspicious demise necessitating autopsy, as stipulated by legal authorities. Chronic disseminated intravascular coagulation (DIC) is an acquired clinical and biological syndrome characterized by a severe and fatal prognosis, stemming from systemic, uncontrolled, diffuse coagulation activation. Irrespective of their origins, DIC is associated with a diverse spectrum of manifestations, encompassing minor biological coagulation alterations to profoundly severe conditions wherein hemorrhagic complications may take precedence. Simultaneously, microthrombi contribute to the development of multi-organ failures. Objective This study seeks to evaluate the role of autopsy in determining the causes of death. Materials and Methods: We present two instances of sudden death involving females who underwent autopsy at the Forensic Medicine Department of the University Hospital of Annaba, Algeria. These autopsies were performed at the request of the prosecutor, aiming to determine the causes of death and illuminate the exact circumstances surrounding it. Methods Utilized: Analysis of the initial information report; Findings from postmortem examinations; Histological assessments and toxicological analyses. Results: The presence of DIC was noted, affecting nearly all veins with distinct etiologies. Conclusion: For the establishment of a meaningful diagnosis: • Thorough understanding of the subject matter is imperative; • Precise alignment with medicolegal data is essential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20disseminated%20intravascular%20coagulation" title="chronic disseminated intravascular coagulation">chronic disseminated intravascular coagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sudden%20death" title=" sudden death"> sudden death</a>, <a href="https://publications.waset.org/abstracts/search?q=autopsy" title=" autopsy"> autopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=causes%20of%20death" title=" causes of death"> causes of death</a> </p> <a href="https://publications.waset.org/abstracts/171956/sudden-death-and-chronic-disseminated-intravascular-coagulation-dic-two-case-reports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171956.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">85</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> Cybersecurity for Digital Twins in the Built Environment: Research Landscape, Industry Attitudes and Future Direction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaznah%20Alshammari">Kaznah Alshammari</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Beach"> Thomas Beach</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Rezgui"> Yacine Rezgui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technological advances in the construction sector are helping to make smart cities a reality by means of cyber-physical systems (CPS). CPS integrate information and the physical world through the use of information communication technologies (ICT). An increasingly common goal in the built environment is to integrate building information models (BIM) with the Internet of Things (IoT) and sensor technologies using CPS. Future advances could see the adoption of digital twins, creating new opportunities for CPS using monitoring, simulation, and optimisation technologies. However, researchers often fail to fully consider the security implications. To date, it is not widely possible to assimilate BIM data and cybersecurity concepts, and, therefore, security has thus far been overlooked. This paper reviews the empirical literature concerning IoT applications in the built environment and discusses real-world applications of the IoT intended to enhance construction practices, people’s lives and bolster cybersecurity. Specifically, this research addresses two research questions: (a) how suitable are the current IoT and CPS security stacks to address the cybersecurity threats facing digital twins in the context of smart buildings and districts? and (b) what are the current obstacles to tackling cybersecurity threats to the built environment CPS? To answer these questions, this paper reviews the current state-of-the-art research concerning digital twins in the built environment, the IoT, BIM, urban cities, and cybersecurity. The results of these findings of this study confirmed the importance of using digital twins in both IoT and BIM. Also, eight reference zones across Europe have gained special recognition for their contributions to the advancement of IoT science. Therefore, this paper evaluates the use of digital twins in CPS to arrive at recommendations for expanding BIM specifications to facilitate IoT compliance, bolster cybersecurity and integrate digital twin and city standards in the smart cities of the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BIM" title="BIM">BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title=" cybersecurity"> cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20twins" title=" digital twins"> digital twins</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20cities" title=" urban cities"> urban cities</a> </p> <a href="https://publications.waset.org/abstracts/131999/cybersecurity-for-digital-twins-in-the-built-environment-research-landscape-industry-attitudes-and-future-direction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131999.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">169</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> The Torah Scroll of the National Library of the Kingdom of Morocco: Parchment Support and Black Ink Analytical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oubelkacem%20Yacine">Oubelkacem Yacine</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Bast%20Hassan"> El Bast Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Bakkali%20Abdelmajid"> El Bakkali Abdelmajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamhasni%20Taibi"> Lamhasni Taibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ettakni%20Mahmoud"> Ettakni Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ait%20Lyazidi%20Saadia"> Ait Lyazidi Saadia</a>, <a href="https://publications.waset.org/abstracts/search?q=Haddad%20Mustapha"> Haddad Mustapha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben-Ncer%20Abdelouahed"> Ben-Ncer Abdelouahed</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Ferrane%20Mohammed"> El Ferrane Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Boufarra%20Abdelkrim"> Boufarra Abdelkrim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work relates to an on-site and completely non-invasive investigation of one of the most famous west Mediterranean Torah Scroll housed at the National Library of the Kingdom of Morocco. The scroll is 26 m long and consists of 143 parchment sheets of 59 cm x 19 cm, exhibiting only black writings; it is of unknown age. The artifact has been restored by the curator staff of the library. The investigation exploring separately the parchment support and the writing black ink aims at: i) the examination of the parchment conservation/degradation state, ii) the identification of the black ink and iii) the identification of the parchment handcrafting materials. For this purpose, the analyses have been based on combining all of elemental XRF and structural Raman, ATR-FT Infrared Red and Fiber Optical Reflectance spectroscopies, in addition to chroma-metric and pH measurements. pH measurements showing values around 6.5 are in concordance with the absence of any visual corrosion related to the parchment acidity. However, on the basis of the relative intensities and frequency shift of amid I (AI) and amid II (AII) vibrational bands of the collagen, ATR-FTIR spectra revealed diffuse hydrolysis and gelatinization of the parchment writing support; diffuse and non-homogeny degradation by gelatinization has been also confirmed by the IG gelatinization index deduced from the NIR bands on the FOR spectra. This IG index, defined as the ratio I (6860 cm-1) / I (6685 cm-1), ranges in the interval 0.98 – 1 and highlights collagen degradation at the molecular level. Sequentially Shifted Excitation Raman measurements (SSERS) crossed to X-ray fluorescence (XRF) ones on the black writings revealed that the black ink used is an iron-copper gall one, while FOR spectra are typical of pure metal gall inks. These later reflectance measurements exclude, thus, any intentional addition of carbon black to the ink recipe. Moreover, no lead white had been used while pre-drawing the writing lines. On another side, ATR-FTIR measurements highlighted the presence of oxalates as ink degradation products. Considering the parchment handcrafting, the combination of XRF and ATR-FTIR measurements led to the assumption that this writing support had been prepared according to ancient Middle East practices; the parchment infrared fingerprint seems identical to that of the Dead Sea scroll. The present multi-technical analyses are the first ones performed on an ancient Judaic written parchment of Morocco; it is under furthering. The investigation will be extended to other parchments belonging to the Jewish Cultural Heritage Museum of Morocco in Casablanca. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=torah%20scroll" title="torah scroll">torah scroll</a>, <a href="https://publications.waset.org/abstracts/search?q=parchment" title=" parchment"> parchment</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20ink" title=" black ink"> black ink</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20analyses" title=" non-invasive analyses"> non-invasive analyses</a>, <a href="https://publications.waset.org/abstracts/search?q=XRF%2FATR-FTIR%2FRAMAN%2FFORS" title=" XRF/ATR-FTIR/RAMAN/FORS"> XRF/ATR-FTIR/RAMAN/FORS</a> </p> <a href="https://publications.waset.org/abstracts/167592/the-torah-scroll-of-the-national-library-of-the-kingdom-of-morocco-parchment-support-and-black-ink-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167592.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">85</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> Smart Meters and In-Home Displays to Encourage Water Conservation through Behavioural Change </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julia%20Terlet">Julia Terlet</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20H.%20Beach"> Thomas H.

Water conservation in urban areas has to be improved by encouraging consumers to adopt more sustainable habits and behaviours. This includes informing and educating them about their households’ water consumption and advising them about ways to achieve significant savings on a daily basis. This paper presents a study conducted in the context of the European FP7 WISDOM Project. By integrating innovative Information and Communication Technologies (ICT) frameworks, this project aims at achieving a change in water savings. More specifically, behavioural change will be attempted by implementing smart meters and in-home displays in a trial group of selected households within Cardiff (UK). Using this device, consumers will be able to receive feedback and information about their consumption but will also have the opportunity to compare their consumption to the consumption of other consumers and similar households. Following an initial survey, it appeared necessary to implement these in-home displays in a way that matches consumer's motivations to save water. The results demonstrated the importance of various factors influencing people’s daily water consumption. Both the relevant literature on the subject and the results of our survey therefore led us to include within the in-home device a variety of elements. It first appeared crucial to make consumers aware of the economic aspect of water conservation and especially of the significant financial savings that can be achieved by reducing their household’s water consumption on the long term. Likewise, reminding participants of the impact of their consumption on the environment by making them more aware of water scarcity issues around the world will help increasing their motivation to save water. Additionally, peer pressure and social comparisons with neighbours and other consumers, accentuated by the use of online social networks such as Facebook or Twitter, will likely encourage consumers to reduce their consumption. Participants will also be able to compare their current consumption to their past consumption and to observe the consequences of their efforts to save water through diverse graphs and charts. Finally, including a virtual water game within the display will help the whole household, children and adults, to achieve significant reductions by providing them with simple tips and advice to save water on a daily basis. Moreover, by setting daily and weekly goals for them to reach, the game will expectantly generate cooperation between family members. Members of each household will indeed be encouraged to work together to reduce their water consumption within different rooms of the house, such as the bathroom, the kitchen, or the toilets. Overall, this study will allow us to understand the elements that attract consumers the most and the features that are most commonly used by the participants. In this way, we intend to determine the main factors influencing water consumption in order to identify the measures that will most encourage water conservation in both the long and short term. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavioural%20change" title="behavioural change">behavioural change</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT%20technologies" title=" ICT technologies"> ICT technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20consumption" title=" water consumption"> water consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20conservation" title=" water conservation"> water conservation</a> </p> <a href="https://publications.waset.org/abstracts/37078/smart-meters-and-in-home-displays-to-encourage-water-conservation-through-behavioural-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37078.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">335</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
