This literature review aims to highlight the ocular complications of monkeypox, SARS-CoV-2, MERS, ebola, H1N1, and zika viruses as the most recent viral pandemics. Since the emergence of the newly resurfacing monkeypox and the novel SARS-CoV-2, research aiming to uncover the effects of these pandemics began right away. Moreover, it also discusses the ocular complications of the vaccines and treatments that were used in the scope of the viral pandemics. To add, this work discussed the role of the eye as an important route of viral transmission, and thereafter, the American Academy of Ophthalmology (AAO) recommendations to reduce the incidence of viral transmission were mentioned. Finally, this paper aims to outline a platform for researchers who are interested in further investigating eye-related viral manifestations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ophthalmology" title="ophthalmology">ophthalmology</a>, <a href="https://publications.waset.org/abstracts/search?q=monkeypox" title=" monkeypox"> monkeypox</a>, <a href="https://publications.waset.org/abstracts/search?q=ebola" title=" ebola"> ebola</a>, <a href="https://publications.waset.org/abstracts/search?q=zika" title=" zika"> zika</a>, <a href="https://publications.waset.org/abstracts/search?q=MERS" title=" MERS"> MERS</a>, <a href="https://publications.waset.org/abstracts/search?q=H1N1" title=" H1N1"> H1N1</a>, <a href="https://publications.waset.org/abstracts/search?q=influenza" title=" influenza"> influenza</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a> </p> <a href="https://publications.waset.org/abstracts/158629/ocular-manifestations-of-recent-viral-pandemics-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158629.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">127</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">52</span> The High Efficiency of Cationic Azo Dye Removal Using Raw, Purified and Pillared Clay from Algerian Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20%20Ramdani">Amina Ramdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20%20Kadeche"> Abdelkader Kadeche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoubida%20%20Taleb"> Zoubida Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Safia%20%20Taleb"> Safia Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this present study is to evaluate the adsorption capacity of a dye, Malachite green, on a local Algerian montmorillonite clay mineral (raw, purified and Cr-pillared). Various parameters influencing the dye adsorption process ie contact time, adsorbent dose, initial concentration of dye, pH of the solution and temperature. Cr pillared clay has been obtained with a better surface character than purified and natural clay. An increase in basal spacing from 12.45 Å (Mont-Na) to 22.88 Å (Mont-PLCr), surface area from 67 m2 /g (Mont-Na) to 102 m2 /g (Mont-PLCr). The experimental results show that the dye adsorption kinetic were fast: 5 min for Cr-pillared clay mineral, and 30 min for raw and purified clay mineral (RC and Mont-Na). The removal efficiency on Mont-PLCr (98.64%) is greater than that of Mont-Na (86.20%) and RC (82.09%). The acidity and basicity of the medium considerably affect the adsorption of the dye. It attained its maximum at pH 4.8. The equilibrium and kinetic data were found to ﬁt well the Langmuir model and the pseudo-second-order model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dye%20removal" title="Dye removal">Dye removal</a>, <a href="https://publications.waset.org/abstracts/search?q=pillared%20clay" title=" pillared clay"> pillared clay</a>, <a href="https://publications.waset.org/abstracts/search?q=isotherm" title=" isotherm"> isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic" title=" kinetic"> kinetic</a> </p> <a href="https://publications.waset.org/abstracts/121475/the-high-efficiency-of-cationic-azo-dye-removal-using-raw-purified-and-pillared-clay-from-algerian-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121475.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">165</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">51</span> Taleb's Complexity Theory Concept of 'Antifragility' Has a Significant Contribution to Make to Positive Psychology as Applied to Wellbeing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudius%20Peter%20Van%20Wyk">Claudius Peter Van Wyk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the increasingly manifest phenomena, as described in complexity theory, of volatility, uncertainty, complexity and ambiguity (VUCA), Taleb's notion of 'antifragility, has a significant contribution to make to positive psychology applied to wellbeing. Antifragility is argued to be fundamentally different from the concepts of resiliency; as the ability to recover from failure, and robustness; as the ability to resist failure. Rather it describes the capacity to reorganise in the face of stress in such a way as to cope more effectively with systemic challenges. The concept, which has been applied in disciplines ranging from physics, molecular biology, planning, engineering, and computer science, can now be considered for its application in individual human and social wellbeing. There are strong correlations to Antonovsky's model of 'salutogenesis' in which an attitude and competencies are developed of transforming burdening factors into greater resourcefulness. We demonstrate, from the perspective of neuroscience, how technology measuring nervous system coherence can be coupled to acquired psychodynamic approaches to not only identify contextual stressors, utilise biofeedback instruments for facilitating greater coherence, but apply these insights to specific life stressors that compromise well-being. Employing an on-going case study with BMW South Africa, the neurological mapping is demonstrated together with 'reframing' and emotional anchoring techniques from neurolinguistic programming. The argument is contextualised in the discipline of psychoneuroimmunology which describes the stress pathways from the CNS and endocrine systems and their impact on immune function and the capacity to restore homeostasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifragility" title="antifragility">antifragility</a>, <a href="https://publications.waset.org/abstracts/search?q=complexity" title=" complexity"> complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroscience" title=" neuroscience"> neuroscience</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoneuroimmunology" title=" psychoneuroimmunology"> psychoneuroimmunology</a>, <a href="https://publications.waset.org/abstracts/search?q=salutogenesis" title=" salutogenesis"> salutogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility" title=" volatility "> volatility </a> </p> <a href="https://publications.waset.org/abstracts/46826/talebs-complexity-theory-concept-of-antifragility-has-a-significant-contribution-to-make-to-positive-psychology-as-applied-to-wellbeing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46826.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">376</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">50</span> Geometric Design to Improve the Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Ghodbane">H.

It is associated with cardio-metabolic diseases. Its prevalence is increasing significantly in both rich and poor countries. However, there are obese people who have no metabolic disturbance. So we think obesity is not always a risk factor for an abnormal metabolic profile that increases the risk of cardiometabolic problems. However, there is no definition that allows us to identify the individual group Metabolically Healthy but Obese (MHO). Objective: The objective of this study is to evaluate the relationship between MHO and some factors associated with it. Methods: A longitudinal study is a prospective cohort study of 600 participants aged ≥18 years. Metabolic status was assessed by the following parameters: blood pressure, fasting glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. Body Mass Index (BMI) was calculated as weight (in kg) divided by height (m2), BMI = Weight/(Height)². According to the BMI value, our population was divided into four groups: underweight subjects with BMI <18.5 kg/m2, normal weight subjects with BMI = 18.5–24.9 kg/m², overweight subjects with BMI=25–29.9 kg/m², and obese subjects who have (BMI ≥ 30 kg/m²). A value of P < 0.05 was considered significant. Statistical processing was done using the SPSS 25 software. Results: During this study, 194 (32.33%) were identified as MHO among 416 (37%) obese individuals. The prevalence of the metabolically unhealthy phenotype among normal-weight individuals was (13.83%) vs. (37%) in obese individuals. Compared with metabolically healthy normal-weight individuals (10.93%), the prevalence of diabetes was (30.60%) in MHO, (20.59%) in metabolically unhealthy normal weight, and (52.29%) for metabolically unhealthy obese (p = 0.032). Blood pressure was significantly higher in MHO individuals than in metabolically healthy normal-weight individuals and in metabolically unhealthy obese than in metabolically unhealthy normal weight (P < 0.0001). Familial coronary artery disease does not appear to have an effect on the metabolic status of obese and normal-weight patients (P = 0.544). However, waist circumference appears to have an effect on the metabolic status of individuals (P < 0.0001). Conclusion: This study showed a high prevalence of metabolic profile disruption in normal-weight subjects and a high rate of overweight and/or obese people who are metabolically healthy. To understand the physiological mechanism related to these metabolic statuses, a thorough study is needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metabolically%20health" title="metabolically health">metabolically health</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20associated" title=" factors associated"> factors associated</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20diseases" title=" cardiovascular diseases"> cardiovascular diseases</a> </p> <a href="https://publications.waset.org/abstracts/158947/metabolically-healthy-obesity-and-protective-factors-of-cardiovascular-diseases-as-a-result-from-a-longitudinal-study-in-tebessa-east-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158947.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">117</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">47</span> Aromatic and Medicinal Plants in Morocco: Diversity and Socio-Economic Role</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sghir%20Taleb">Mohammed Sghir Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Morocco is characterized by a great richness and diversity in aromatic and medicinal plants and it has an ancestral knowledge in the use of plants for medicinal and cosmetic purposes.

This controller is used to control the output power of high frequency resonant inverter with LLC tank. One of the most important problems associated with the proposed inverter is achieving ZVS operating during the induction heating process. To overcome this problem, asymmetrical voltage cancellation (AVC) control technique is proposed. The phased look loop (PLL) is used to track the natural frequency of the system. The small signal model of the system with the proposed control is obtained using extending describing function method (EDM). The validity of the proposed control is verified by simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20heating" title="induction heating">induction heating</a>, <a href="https://publications.waset.org/abstracts/search?q=AVC%20control" title=" AVC control"> AVC control</a>, <a href="https://publications.waset.org/abstracts/search?q=CDM" title=" CDM"> CDM</a>, <a href="https://publications.waset.org/abstracts/search?q=PLL" title=" PLL"> PLL</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20inverter" title=" resonant inverter "> resonant inverter </a> </p> <a href="https://publications.waset.org/abstracts/18666/cdm-based-controller-design-for-high-frequency-induction-heating-system-with-llc-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18666.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">664</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">45</span> Defect Profile Simulation of Oxygen Implantation into Si and GaAs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Dahbi">N.

SRIM simulation results indicate that the implanted ions have a profile as a function of Gaussian-type; oxygen produced more vacancies and implanted deeper in Si compared to GaAs. Also, most of the energy loss is due to ionization and phonon production, where vacancy production amounts to few percent of the total energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defect%20profile" title="defect profile">defect profile</a>, <a href="https://publications.waset.org/abstracts/search?q=GaAs" title=" GaAs"> GaAs</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20implantation" title=" ion implantation"> ion implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=SRIM" title=" SRIM"> SRIM</a>, <a href="https://publications.waset.org/abstracts/search?q=phonon%20production" title=" phonon production"> phonon production</a>, <a href="https://publications.waset.org/abstracts/search?q=vacancies" title=" vacancies"> vacancies</a> </p> <a href="https://publications.waset.org/abstracts/97753/defect-profile-simulation-of-oxygen-implantation-into-si-and-gaas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97753.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">184</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">44</span> Detergent Removal from Rinsing Water by Peroxi Electrocoagulation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Benhadji">A.

In this study, Peroxi Electrocoagulation Process (PEP) was investigated for the treatment of detergent wastewater. The process was compared with electrooxidation treatment. The results showed that chemical oxygen demand (COD) was high 7584 mgO<sub>2</sub>.L<sup>-1</sup>, while the biochemical oxygen demand was low (250 mgO<sub>2</sub>.L<sup>-1</sup>). This wastewater was hardly biodegradable. Electrochemical process was carried out for the removal of detergent using a glass reactor with a volume of 1 L and fitted with three electrodes. A direct current (DC) supply was used. Samples were taken at various current density (0.0227 A/cm<sup>2</sup> to 0.0378 A/cm<sup>2</sup>) and reaction time (1-2-3-4 and 5 hour). Finally, the COD was determined. The results indicated that COD removal efficiency of PEP was observed to increase with current intensity and reached to 77% after 5 h. The highest removal efficiency was observed after 5 h of treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AOP" title="AOP">AOP</a>, <a href="https://publications.waset.org/abstracts/search?q=COD" title=" COD"> COD</a>, <a href="https://publications.waset.org/abstracts/search?q=detergent" title=" detergent"> detergent</a>, <a href="https://publications.waset.org/abstracts/search?q=PEP" title=" PEP"> PEP</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater "> wastewater </a> </p> <a href="https://publications.waset.org/abstracts/111520/detergent-removal-from-rinsing-water-by-peroxi-electrocoagulation-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111520.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">119</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">43</span> A Comparative Analysis of Multicarrier SPWM Strategies for Five-Level Flying Capacitor Inverter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Belmadani">Bachir Belmadani</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Taleb"> Rachid Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Zinelaabidine%20Boudjema"> Zinelaabidine Boudjema</a>, <a href="https://publications.waset.org/abstracts/search?q=Adil%20Yahdou"> Adil Yahdou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carrier-based methods have been used widely for switching of multilevel inverters due to their simplicity, flexibility and reduced computational requirements compared to space vector modulation (SVM).

The underlying molecular defects affecting mitochondrial CIII assembly factors are few and yet to be identified. LYRM7 assembly factor is required for proper CIII assembly where it acts as a chaperone for the Rieske iron‐sulfur (UQCRFS1) protein in the mitochondrial matrix and stabilizing it. We present here the seventeenth individual with LYRM7-associated mitochondrial leukoencephalopathy harboring a previously reported rare pathogenic homozygous LYRM 7 variant, c.2T>C, (p.Met1?). Like previously reported individuals, our 4-year-old male proband presented with recurrent metabolic and lactic acidosis, encephalopathy, and myopathy. Further, he has additional, previously unreported features, including an acute stroke like episode with bilateral central blindness and optic neuropathy, recurrent hyperglycemia and hypertension associated with metabolic crisis. However, he has no signs of psychomotor regression. He has been stable clinically with residual left-sided reduced visual acuity and amblyopia, and no more metabolic crises for 2-year-period while on the mitochondrial cocktail. Although the reported brain MRI findings in other affected individuals are homogenous, it is slightly different in our index, revealing evidence of bilateral almost symmetric multifocal periventricular T2 hyperintensities with hyperintensities of the optic nerves, optic chiasm, and corona radiata but with no cavitation or cystic changes. This report describes new clinical and radiological findings of LYRM7-associated disease. The report also summarizes the clinical and molecular data of previously reported individuals describing the full phenotypic spectrum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LYRM7%20gene%20defect" title="LYRM7 gene defect">LYRM7 gene defect</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20disease" title=" mitochondrial disease"> mitochondrial disease</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=" "> </a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acidosis" title="lactic acidosis">lactic acidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=" "> </a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20disorder" title="genetic disorder">genetic disorder</a> </p> <a href="https://publications.waset.org/abstracts/160478/lyrm7-associated-mitochondrial-complex-iii-deficiency-with-non-cavitating-leukoencephalopathy-and-stroke-like-episodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160478.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">72</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">36</span> OMTHD Strategy in Asymmetrical Seven-Level Inverter for High Power Induction Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Taleb">Rachid Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=M%E2%80%99hamed%20Helaimi"> M’hamed Helaimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Djilali%20Benyoucef"> Djilali Benyoucef</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Derrouazin"> Ahmed Derrouazin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multilevel inverters are well used in high power electronic applications because of their ability to generate a very good quality of waveforms, reducing switching frequency, and their low voltage stress across the power devices.

They are toxic and considered carcinogenic and dangerous even when they exist in trace amounts. At Algiers refinery, production, transportation, and refining of crude oil generate considerable waste in storage tanks; these residues result from the gravitational settling. The composition of these residues is essentially a mixture of hydrocarbon and lead. We propose in this work the application of electrooxidation treatment for the leachate of the leaden sludge. The effect of pH, current density and the electrolysis time were studied, the effectiveness of the processes is evaluated by measuring the chemical oxygen demand (COD). The dissolution is the best way to mobilize pollutants from leaden mud, so we conducted leaching before starting the electrochemical treatment. The process was carried out in batch mode using graphite anode and a stainless steel cathode. The results clearly demonstrate the compatibility of the technique used with the type of pollution studied. In fact, it allowed COD removal about 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrooxidation" title="electrooxidation">electrooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a>, <a href="https://publications.waset.org/abstracts/search?q=leaden%20sludge" title=" leaden sludge"> leaden sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20industry" title=" oil industry"> oil industry</a> </p> <a href="https://publications.waset.org/abstracts/35672/treatment-of-leaden-sludge-of-algiers-refinery-by-electrooxidation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35672.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Comparative Methods for Speech Enhancement and the Effects on Text-Independent Speaker Identification Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Ajgou">R.

Though the majority of the existing solutions provide good accuracy results, they are often overly complex and computationally expensive. In this perspective, we propose the use of dimensionality reduction techniques to address the problem of facial pose estimation. Firstly, a face image is converted into one-dimensional time series using Hilbert space filling curve, then the approach converts these time series data to a symbolic representation. Furthermore, a distance matrix is calculated between symbolic series of an input learning dataset of images, to generate classifiers of frontal vs. profile face pose. The proposed method is evaluated with three public datasets. Experimental results have shown that our approach is able to achieve a correct classification rate exceeding 97% with K-NN algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title=" pattern recognition"> pattern recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=facial%20pose%20classification" title=" facial pose classification"> facial pose classification</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series "> time series </a> </p> <a href="https://publications.waset.org/abstracts/33324/facial-pose-classification-using-hilbert-space-filling-curve-and-multidimensional-scaling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33324.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">350</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">32</span> A Value-Oriented Metamodel for Small and Medium Enterprises’ Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Romain%20Ben%20Taleb">Romain Ben Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Aur%C3%A9lie%20Montarnal"> Aurélie Montarnal</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthieu%20Lauras"> Matthieu Lauras</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Dahan"> Mathieu Dahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Miclo"> Romain Miclo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To be competitive and sustainable, any company has to maximize its value. However, unlike listed companies that can assess their values based on market shares, most Small and Medium Enterprises (SMEs) which are non-listed cannot have direct and live access to this critical information. Traditional accounting reports only give limited insights to SME decision-makers about the real impact of their day-to-day decisions on the company’s performance and value. Most of the time, an SME’s financial valuation is made one time a year as the associated process is time and resource-consuming, requiring several months and external expertise to be completed. To solve this issue, we propose in this paper a value-oriented metamodel that enables real-time and dynamic assessment of the SME’s value based on the large definition of their assets. These assets cover a wider scope of resources of the company and better account for immaterial assets. The proposal, which is illustrated in a case study, discusses the benefits of incorporating assets in the SME valuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SME" title="SME">SME</a>, <a href="https://publications.waset.org/abstracts/search?q=metamodel" title=" metamodel"> metamodel</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20system" title=" decision support system"> decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20valuation" title=" financial valuation"> financial valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=assets" title=" assets"> assets</a> </p> <a href="https://publications.waset.org/abstracts/155809/a-value-oriented-metamodel-for-small-and-medium-enterprises-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155809.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">92</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">31</span> Low-Level Forced and Ambient Vibration Tests on URM Building Strengthened by Dampers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Taleb">Rafik Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Bouriche"> Farid Bouriche</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Boukri"> Mehdi Boukri</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouad%20Kehila"> Fouad Kehila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the paper is to investigate the dynamic behavior of an unreinforced masonry (URM) building strengthened by DC-90 dampers by ambient and low-level forced vibration tests. Ambient and forced vibration techniques are usually applied to reinforced concrete or steel buildings to understand and identify their dynamic behavior, however, less is known about their applicability for masonry buildings. Ambient vibrations were measured before and after strengthening of the URM building by DC-90 dampers system. For forced vibration test, a series of low amplitude steady state harmonic forced vibration tests were conducted after strengthening using eccentric mass shaker. The resonant frequency curves, mode shapes and damping coefficients as well as stress distribution in the steel braces of the DC-90 dampers have been investigated and could be defined. It was shown that the dynamic behavior of the masonry building, even if not regular and with deformable floors, can be effectively represented. It can be concluded that the strengthening of the building does not change the dynamic properties of the building due to the fact of low amplitude excitation which do not activate the dampers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20vibrations" title="ambient vibrations">ambient vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20buildings" title=" masonry buildings"> masonry buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20vibrations" title=" forced vibrations"> forced vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20dynamic%20identification" title=" structural dynamic identification"> structural dynamic identification</a> </p> <a href="https://publications.waset.org/abstracts/41511/low-level-forced-and-ambient-vibration-tests-on-urm-building-strengthened-by-dampers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41511.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">408</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">30</span> Surface Hole Defect Detection of Rolled Sheets Based on Pixel Classification Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Taleb">Samira Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakina%20Aoun"> Sakina Aoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Slimane%20Ziani"> Slimane Ziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoheir%20Mentouri"> Zoheir Mentouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Boudiaf"> Adel Boudiaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rolling is a pressure treatment technique that modifies the shape of steel ingots or billets between rotating rollers. During this process, defects may form on the surface of the rolled sheets and are likely to affect the performance and quality of the finished product. In our study, we developed a method for detecting surface hole defects using a pixel classification approach. This work includes several steps. First, we performed image preprocessing to delimit areas with and without hole defects on the sheet image. Then, we developed the histograms of each area to generate the gray level membership intervals of the pixels that characterize each area. As we noticed an intersection between the characteristics of the gray level intervals of the images of the two areas, we finally performed a learning step based on a series of detection tests to refine the membership intervals of each area, and to choose the defect detection criterion in order to optimize the recognition of the surface hole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification" title="classification">classification</a>, <a href="https://publications.waset.org/abstracts/search?q=defect" title=" defect"> defect</a>, <a href="https://publications.waset.org/abstracts/search?q=surface" title=" surface"> surface</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=hole" title=" hole"> hole</a> </p> <a href="https://publications.waset.org/abstracts/193037/surface-hole-defect-detection-of-rolled-sheets-based-on-pixel-classification-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193037.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">29</span> Extraction of Urban Land Features from TM Landsat Image Using the Land Features Index and Tasseled Cap Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Bouhennache">R.

Biodiversity and natural ecosystems provide the local population with highly diversified services represented by aromatic and medicinal plants, forage plants, melliferous plants, firewood, lumber, mushrooms, etc. Ecosystem services are currently subject to many pressures: overgrazing and deforestation, climate change, including increased drought, urbanization and forest fire. Conscious of the risks that weigh on biodiversity and ecosystem services, Morocco had made an important effort to reverse the tendencies by developing a consistent biodiversity conservation strategy focused on in-situ and ex-situ conservation. This presentation will be focused on the current state of biodiversity and ecosystem services and their role for the human development and their decline under the action of different pressures (grazing, timber harvest, harvesting of medicinal and aromatic plants, charcoal making...) while emphasizing efforts constructed by Morocco to conserve and sustainably manage biodiversity and ecosystem services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=morocco" title="morocco">morocco</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20services" title=" ecosystem services"> ecosystem services</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20population" title=" local population"> local population</a> </p> <a href="https://publications.waset.org/abstracts/168170/biodiversity-and-ecosystem-services-in-morocco-current-state-and-human-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168170.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">93</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">27</span> Survey of Corrosion and Scaling of Urban Drinking Water Supply Reservoirs (Case Study: Ilam City) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Derikvand">Ehsan Derikvand</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Kaykha"> Hamid Kaykha</a>, <a href="https://publications.waset.org/abstracts/search?q=Rooholah%20Mansoori%20Yekta"> Rooholah Mansoori Yekta</a>, <a href="https://publications.waset.org/abstracts/search?q=Taleb%20Javanmard"> Taleb Javanmard</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Mehdi%20Zadeh"> Mohsen Mehdi Zadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corrosion and scaling are one of the most complicated and costly problems of drinking water supply.

It encompasses an agricultural domain covering an area of 181,097 hectares, of which 143,451 hectares are considered arable land. A field study was conducted along a west-to-east transect, covering six zones within the province, including Maacem, Ammari, Tissemsilt, Khemisti, Laayoune, Theniet el Had, and Taza. Random soil samples were collected from each region for laboratory analyses to assess soil types and quality, ultimately aiming to identify soil diversity within the Tissemsilt Province. Within the agricultural zones, approximately 40 soil samples were collected, revealing that the province contains moderately high-quality clayey soils, semi-rich in organic matter. However, as one moves southward, this richness diminishes. This leads us to predict that the agricultural zone is an ideal region for cereal cultivation. Nonetheless, this situation is challenged by the decreasing precipitation, which affects overall yields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil" title="soil">soil</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-arid" title=" semi-arid"> semi-arid</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/175182/examination-of-the-socioeconomic-impact-of-soil-diversity-in-semi-arid-regions-on-agriculture-a-case-study-in-the-tissemsilt-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175182.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">71</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">25</span> Applying ASHRAE Standards on the Hospital Buildings of UAE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20M.%20Taleb">Hanan M. Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy consumption associated with buildings has a significant impact on the environment. To that end, and as a transaction between the inside and outside and between the building and urban space, the building skin plays an especially important role. It provides protection from the elements; demarcates private property and creates privacy. More importantly, it controls the admission of solar radiation. Therefore, designing the building skin sustainably will help to achieve optimal performance in terms of both energy consumption and thermal comfort. Unfortunately, with accelerating construction expansion, many recent buildings do not pay attention to the importance of the envelope design. This piece of research will highlight the importance of this part of the creation of buildings by providing evidence of a significant reduction in energy consumption if the envelopes are redesigned. Consequently, the aim of this paper is to enhance the performance of the hospital envelope in order to achieve sustainable performance. A hospital building sited in Abu Dhabi, in the UAE, has been chosen to act as a case study. A detailed analysis of the annual energy performance of the case study will be performed with the use of a computerised simulation; this is in order to explore their energy performance shortcomings. The energy consumption of the base case will then be compared with that resulting from the new proposed building skin. The results will inform architects and designers of the savings potential from various strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASHREA" title="ASHREA">ASHREA</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20skin" title=" building skin"> building skin</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20envelopes" title=" building envelopes"> building envelopes</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitals" title=" hospitals"> hospitals</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu%20Dhabi" title=" Abu Dhabi"> Abu Dhabi</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a>, <a href="https://publications.waset.org/abstracts/search?q=IES%20software" title=" IES software"> IES software</a> </p> <a href="https://publications.waset.org/abstracts/5386/applying-ashrae-standards-on-the-hospital-buildings-of-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5386.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">364</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">24</span> Natural Forest Ecosystem Services and Local Populations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sghir%20Taleb">Mohammed Sghir Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Located at the northwest corner of the African continent between 21 ° and 36 ° north latitude and between the 1st and the 17th degree of west longitude, Morocco, with a total area of 715,000 km², enjoys a privileged position with a coastline of 3 446 km long opening to the Mediterranean and the Atlantic Ocean. Its privileged location with a double coastline and its diverse mountain with four major mountain ranges: the Rif, Middle Atlas, High Atlas, and Anti Atlas, with altitudes exceeding 2000 m in the Rif, 3000 m in the Middle Atlas, and 4000 m in the High Atlas. Morocco is characterized by an important forest genetic diversity represented by a rich and varied flora and many ecosystems: forest, preforest, presteppe, steppe, Sahara that spans a range of bioclimatic zones: arid, semiarid, subhumid, and humid. The vascular flora of Morocco is rich and highly diversified, with a very significant degree of endemism. Natural flora and ecosystems provide important services to populations represented by grazing, timber harvest, harvesting of medicinal and aromatic plants. This work will be focused on the Moroccan biodiversity and natural ecosystem services and on the interaction between local populations and ecosystems <p class="card-text"><strong>Keywords:</strong> <a
