We argue that the assessment of these effects needs a detailed analysis of spillovers according to the source of knowledge with respect to formal and informal patent citations made in European and internal search, the horizontal and vertical mechanisms by which knowledge spillovers take place, and the technological characteristics of innovative firms that able them to absorb external knowledge and integrate it in their existing innovation process. We use OECD data and find evidence that knowledge spillovers occur only from horizontal and backward linkages. The importance of these effects depends on the type of citation, in which the references to non-patent literature (informal citations made in European and international searches) have a greater impact. In addition, only firms with high technological capacities benefit from knowledge spillovers from formal and informal citations. Low-technology firms fail to catch up and efficiently learn external knowledge from patent citations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation%20performance" title="innovation performance">innovation performance</a>, <a href="https://publications.waset.org/abstracts/search?q=patent%20citation" title=" patent citation"> patent citation</a>, <a href="https://publications.waset.org/abstracts/search?q=absorptive%20capacity" title=" absorptive capacity"> absorptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20spillover%20mechanisms" title=" knowledge spillover mechanisms"> knowledge spillover mechanisms</a> </p> <a href="https://publications.waset.org/abstracts/162143/knowledge-spillovers-from-patent-citations-evidence-from-swiss-manufacturing-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162143.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">110</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> A Technical-Economical Study of a New Solar Tray Distillator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Diaf">Abderrahmane Diaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Assia%20Cherfa"> Assia Cherfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Karadaniz"> Lamia Karadaniz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple tray solar distillation offers an interesting alternative for small-scale desalination and production high quality distilled water at a competitive cost using solar energy.

For this reason, the ultrasound images are difficult to use automatically in clinical use, then treatments are required for this type of images. Then a filtering procedure of these images is necessary to eliminate the speckle noise and to improve the quality of ultrasound images which will be then segmented to extract the necessary forms that exist. In this paper, we present the importance of the pre-treatment step for segmentation. This work is applied to cardiac ultrasound images.

The RHS frequency once obtained is used as a key parameter into a simple developed expression to directly compute the eccentricity fault frequencies in the induction machine. Experimental tests performed for both a healthy motor and a faulty motor with different eccentricity fault severities illustrate the effectiveness and merits of the proposed EFD algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=squirrel%20cage%20motor" title="squirrel cage motor">squirrel cage motor</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=eccentricity%20faults" title=" eccentricity faults"> eccentricity faults</a>, <a href="https://publications.waset.org/abstracts/search?q=current%20spectral%20analysis" title=" current spectral analysis"> current spectral analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rotor%20slot%20harmonic" title=" rotor slot harmonic"> rotor slot harmonic</a> </p> <a href="https://publications.waset.org/abstracts/71112/induction-motor-eccentricity-fault-recognition-using-rotor-slot-harmonic-with-stator-current-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71112.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">487</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">42</span> Induction Motor Stator Fault Analysis Using Phase-Angle and Magnitude of the Line Currents Spectra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hamida%20Boudinar">Ahmed Hamida Boudinar</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Benouzza"> Noureddine Benouzza</a>, <a href="https://publications.waset.org/abstracts/search?q=Azeddine%20Bendiabdellah"> Azeddine Bendiabdellah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El%20Amine%20Khodja"> Mohamed El Amine Khodja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a new diagnosis approach for identification of the progressive stator winding inter-turn short-circuit fault in induction motor.

We distinguish two categories: objective and subjective measures. The first one depends on a fixed threshold and on data quality from which the rules are extracted. The second one consists on providing to the expert some tools in the objective to explore and visualize rules during the evaluation step. However, the number of extracted rules to validate remains high. Thus, the manually mining rules task is very hard. To solve this problem, we propose, in this paper, a semi-automatic method to assist the expert during the association rule's validation. Our method uses rule-based classification as follow: (i) We transform association rules into classification rules (classifiers), (ii) We use the generated classifiers for data classification. (iii) We visualize association rules with their quality classification to give an idea to the expert and to assist him during validation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title="association rules">association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=rule-based%20classification" title=" rule-based classification"> rule-based classification</a>, <a href="https://publications.waset.org/abstracts/search?q=classification%20quality" title=" classification quality"> classification quality</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a> </p> <a href="https://publications.waset.org/abstracts/29443/semi-automatic-method-to-assist-expert-for-association-rules-validation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29443.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">439</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">40</span> Isolation and Identification of Fungal Pathogens in Palm Groves of Oued Righ </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakhdari%20Wassima">Lakhdari Wassima</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouffroukh%20Ammar"> Ouffroukh Ammar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dahliz%20Abderrahm%C3%A8ne"> Dahliz Abderrahmène</a>, <a href="https://publications.waset.org/abstracts/search?q=Soud%20Adila"> Soud Adila</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammi%20Hamida"> Hammi Hamida</a>, <a href="https://publications.waset.org/abstracts/search?q=M%E2%80%99lik%20Randa"> M’lik Randa </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prospected palm groves of Oued Righ regions (Ouargla, Algeria) allowed us to observe sudden death of palm trees aged between 05 and 70 years. Field examinations revealed abnormal clinical signs with sometimes a quick death of affected trees. Entomologic investigations have confirmed the absence of phytophagous insects on dead trees. Further investigations by questioning farmers on the global management of palm groves visited (Irrigation, water quality used, soil type, etc.) did not establish any relationship between these aspects and the death of palm trees, which naturally pushed us to focus our investigations for research on fungal pathogens. Thus, laboratory studies were conducted to know the real causes of this phenomenon, 13 fungi were found on different parts of the dead palm trees. The flowing fungal types were identified: 1-Diplodia phoenicum, 2-Theilaviopsis paradoxa, 3-Phytophthora sp, 4-Helminthosporium sp, 5-Stemphylium botryosum, 6-Alternaria sp, 7-Aspergillus niger, 8-Aspergillus sp. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20tree" title="palm tree">palm tree</a>, <a href="https://publications.waset.org/abstracts/search?q=death" title=" death"> death</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20pathogens" title=" fungal pathogens"> fungal pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=Oued%20Righ" title=" Oued Righ "> Oued Righ </a> </p> <a href="https://publications.waset.org/abstracts/14128/isolation-and-identification-of-fungal-pathogens-in-palm-groves-of-oued-righ" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14128.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">414</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">39</span> Microwave Assisted Extractive Desulfurization of Gas Oil Feedstock</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamida%20Y.%20Mostafa">Hamida Y.

Solvent extraction, oxidative desulfurization, or hydro-treatment techniques have traditionally been used as the removal processes. While all methods were capable of eliminating sulfur compounds at moderate rates, they had some limitations. A major problem with these routes is their high running expenses, which are caused by their prolonged operation times and high energy consumption. Therefore, new methods for removing sulfur are still necessary. In the current study, a simple assisted desulfurization system for gas oil fraction has been successfully developed using acetonitrile and methanol as a solvent under microwave irradiation. The key variables affecting sulfur removal have been studied, including microwave power, irradiation time, and solvent to gas oil volume ratio. At the conclusion of the research that is being presented, promising results have been found. The results show that a microwave-assisted extractive desulfurization method had remove sulfur with a high degree of efficiency under the suitable conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extractive%20desulfurization" title="extractive desulfurization">extractive desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20assisted%20extraction" title=" microwave assisted extraction"> microwave assisted extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20fractions" title=" petroleum fractions"> petroleum fractions</a>, <a href="https://publications.waset.org/abstracts/search?q=acetonitrile%20and%20methanol" title=" acetonitrile and methanol"> acetonitrile and methanol</a> </p> <a href="https://publications.waset.org/abstracts/167883/microwave-assisted-extractive-desulfurization-of-gas-oil-feedstock" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167883.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">103</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">38</span> Identification of the Alkaloids of the Belladone (Atropa belladonna L.) and Evaluation of Their Inhibitory Effects Against Some Microbial Strains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ait%20Slimane-Ait%20Kaki%20Sabrina">Ait Slimane-Ait Kaki Sabrina</a>, <a href="https://publications.waset.org/abstracts/search?q=Foudi%20Lamia"> Foudi Lamia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work consists of the study of the bio-ecology and the therapeutic effects of the belladone (Atropa belladonna L.).

The phytochemical analysis of leaves revealed alkaloids, tannins, catechin, coumarins, mucilages, saponins, starch, and reducing compounds. The experimental study concerns the extraction and characterization of belladonna alkaloids. Analysis of the purified extract by staining tests confirmed the presence of tropane alkaloids. The dosage chromatography revealed the presence of components that have been identified atropine, scopolamine and hyoscyamine. Evaluation of antimicrobial and antifungal alkaloids from the methanol extract and aqueous extract of belladonna on pathogenic germs showed a positive bactericidal against strains of Escherichia coli and Staphylococcus aureus.

While extensive research has been conducted on its systemic manifestations, the specific dental implications of WS remain poorly understood. The medical history and the oral health status of two patients diagnosed with WS were detailed. Our findings revealed a high prevalence of dental problems in both patients, including periodontitis, xerostomia, and temporomandibular joint disorders. This article aims to investigate the dental challenges faced by individuals with WS as well as the prosthetic options envisaged through two clinical cases contributing to a deeper understanding of the dental implications of WS and to choose the appropriate prosthetic solution in this population. Future research should focus on larger scale studies and clinical trials to validate these proposed strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20progeria" title="adult progeria">adult progeria</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20symptoms" title=" clinical symptoms"> clinical symptoms</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20manifestations" title=" oral manifestations"> oral manifestations</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care" title=" dental care"> dental care</a>, <a href="https://publications.waset.org/abstracts/search?q=prosthetic%20management" title=" prosthetic management"> prosthetic management</a> </p> <a href="https://publications.waset.org/abstracts/186691/dental-management-particularities-of-werner-syndrome-a-report-of-two-cases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186691.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">51</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> Bio-Oil Production and Chromatographic Characterization from the Pyrolysis of Oil Palm Empty Fruit Bunches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arif%20Ferdiyanto">Arif Ferdiyanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Fajar%20Hamida"> Fajar Hamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20Hidayat"> Arif Hidayat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil palm empty fruit bunches, derived biomass available in Indonesia, is one of the potential biomass to produce biofuels like bio-oil due to its abundant supply and favorable physicochemical characteristics. An interesting alternative of utilising the oil palm empty fruit bunches is in the production of bio-oil by pyrolysis. Pyrolysis of oil palm empty fruit bunches to bio-oil is being considered for national energy security and environmental advantages. The aim of this study was to produce bio-oil by pyrolysis of oil palm empty fruit bunches at various temperature and observe its detailed chemical composition. The biomass was submitted to a pyrolysis in a batch reactor. Experiments were carried out at a temperature range of 450–600°C and heating rate range of 10-20°C/min. The yield of bio-oil was found to be maximum at the temperature of 600°C. The bio-oils detailed compositions were investigated using FTIR and GC-MS. The bio-char produced as a co-product can be a potential soil amendment with multiple benefits including soil fertility and for solid fuel applications that also contributes to the preservation of the environment. The present investigation suggests the suitability of oil palm empty fruit bunches as a potential feedstock for exploitation of energy and biomaterials through pyrolysis process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-oil" title="bio-oil">bio-oil</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20empty%20fruit%20bunches" title=" oil palm empty fruit bunches"> oil palm empty fruit bunches</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title=" pyrolysis"> pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/66672/bio-oil-production-and-chromatographic-characterization-from-the-pyrolysis-of-oil-palm-empty-fruit-bunches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66672.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">341</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">35</span> Coordination Polymer Hydrogels Based on Coinage Metals and Nucleobase Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamia%20L.%20G.%20Al-Mahamad">Lamia L.

We set up an iterative process including data visualization and analysis, identification and extraction of information related to the area concerned by the operation, design of sustainable planning scenarios leveraging local renewable and recoverable energy sources, and finally, the evaluation of scenarios.

In this study, photocatalytic degradation of a widely used textile dye, Acid Blue 25 (AB25), with noble metal loaded ZnO photocatalyst (Ag/ZnO), was investigated in aqueous suspension under solar light. The results showed that the deposition of Ag as a noble metal onto the ZnO surface, improved the photodegradation of AB25. . The effect of different parameters such as catalyst dose, initial dye concentration, and contact time was optimized and the optimal degradation of AB25 (97%) was achieved for initial AB25 concentration of 24 mg L−1 an catalyst dose of 1 g L−1 at natural pH (5.42) after 180 min. The kinetic studies were achieved and revealed that the photocatalytic degradation process obeyed to Langmuir–Hinshelwood model and followed a pseudo-first order rate expression.

To maintain the switching frequency, the approach is to incorporate a pulse-width modulation that utilizes an equivalent control, inferred by applying the SM control method, to produce a control sign to be contrasted and the ﬁxed-frequency within the modulator. Detailed stability and transient performance analysis have been conducted using Lyapunov stability criteria to restrict the switching frequency variation facing wide variations in output load, input changes, and set-point changes. The results obtained confirm the effectiveness of the proposed control scheme in achieving an enhanced output transient performance while faithfully realizing its control objective in the event of abrupt and uncertain parameter variations. Simulations studies in MATLAB/Simulink environment are performed to confirm the idea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC-DC%20converter" title="DC-DC converter">DC-DC converter</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20width%20modulation" title=" pulse width modulation"> pulse width modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20electronics" title=" power electronics"> power electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title=" sliding mode control"> sliding mode control</a> </p> <a href="https://publications.waset.org/abstracts/130515/fixed-frequency-pulse-width-modulation-based-sliding-mode-controller-for-switching-multicellular-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130515.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">147</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> Dual-Channel Multi-Band Spectral Subtraction Algorithm Dedicated to a Bilateral Cochlear Implant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathi%20Kallel">Fathi Kallel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ben%20Hamida"> Ahmed Ben Hamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Berger-Vachon"> Christian Berger-Vachon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a Speech Enhancement Algorithm based on Multi-Band Spectral Subtraction (MBSS) principle is evaluated for Bilateral Cochlear Implant (BCI) users.

The enhanced speech signal is obtained using Dual-Channel Multi-Band Spectral Subtraction ‘DC-MBSS’ algorithm. For performance evaluation, objective speech assessment test relying on Perceptual Evaluation of Speech Quality (PESQ) score is performed to fix the optimal number of frequency bands needed in DC-MBSS algorithm. In order to evaluate the speech intelligibility, subjective listening tests are assessed with 3 deafened BCI patients. Experimental results obtained using French Lafon database corrupted by an additive babble noise at different Signal-to-Noise Ratios (SNR) showed that DC-MBSS algorithm improves speech understanding for single and multiple interfering noise sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speech%20enhancement" title="speech enhancement">speech enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20substracion" title=" spectral substracion"> spectral substracion</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20estimation" title=" noise estimation"> noise estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=cochlear%20impalnt" title=" cochlear impalnt"> cochlear impalnt</a> </p> <a href="https://publications.waset.org/abstracts/18785/dual-channel-multi-band-spectral-subtraction-algorithm-dedicated-to-a-bilateral-cochlear-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18785.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">549</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> Effect of Gender Norms and Gender Equality on Depression and Quality of Life among Young and Old Married Couples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Musarrat%20Jabeen">Musarrat Jabeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zahra%20Khan"> Fatima Zahra Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamida%20Bano"> Hamida Bano</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiza%20Anjum"> Faiza Anjum</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Tahir"> Sara Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Kainat%20Umar"> Kainat Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzma%20Azam"> Uzma Azam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to examine the effect of gender norms and gender equality on depression and quality of life among young and old married couples. The sample consisted of 60 old and 100 young married couples. It was mainly conducted in Islamabad, Pakistan. However, since it was convenient and snowball sampling, we were able to get the data from other cities of Pakistan as well. By using Beck Depression Scale (Aaron T. Beck), Satisfaction with Life Scale (Diener), the Ambivalent Sexism Inventory (Glick & Fiske,1996), and Gender Norms Attitude Scale(Waszak et al., 2000). It was found that the old couples have a high quality of life than young couples, which further proved them to have positive attitude towards gender equality, negative attitude towards gender norms and low level of depression. Also, couples having positive attitude towards gender equality have high level of satisfaction with life than the ones having negative attitude towards gender norms, who have low level of depression. Also, having a negative attitude towards gender norms has adverse effects on the level of depression. To achieve a high quality of life, it would be helpful to evolve with the world, especially with respect to the concepts of gender norms and equality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depression" title="depression">depression</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20equality" title=" gender equality"> gender equality</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20norms" title=" gender norms"> gender norms</a>, <a href="https://publications.waset.org/abstracts/search?q=married%20couples" title=" married couples"> married couples</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/120055/effect-of-gender-norms-and-gender-equality-on-depression-and-quality-of-life-among-young-and-old-married-couples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120055.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">162</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">28</span> Risk Management and Security Practice in Customs Supply Chain: Application of Cross ABC Method to the Moroccan Customs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Hammadi">Lamia Hammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellah%20Ait%20Ouhman"> Abdellah Ait Ouhman</a>, <a href="https://publications.waset.org/abstracts/search?q=Aomar%20Ibourk"> Aomar Ibourk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is widely assumed that the case of Customs Supply Chain is classified as a complex system, due to not only the variety and large number of actors, but also their complex structural links, and the interactions between these actors, that’s why this system is subject to various types of Risks. The economic, political and social impacts of those risks are highly detrimental to countries, businesses and the public, for this reason, Risk management in the customs supply chain is becoming a crucial issue to ensure the sustainability, security and safety. The main characteristic of customs risk management approach is determining which goods and means of transport should be examined? To what extend? And where future compliance resources should be directed? The purposes of this article are, firstly to deal with the concept of customs supply chain, secondly present our risk management approach based on Cross Activity Based Costing (ABC) Method as an interactive tool to support decision making in customs risk management. Finally, analysis of case study of Moroccan customs to putting theory into practice and will thus draw together the various elements of a structured and efficient risk management approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20ABC%20method" title="cross ABC method">cross ABC method</a>, <a href="https://publications.waset.org/abstracts/search?q=customs%20supply%20chain" title=" customs supply chain"> customs supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/8638/risk-management-and-security-practice-in-customs-supply-chain-application-of-cross-abc-method-to-the-moroccan-customs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8638.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">379</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> Volatility and Stylized Facts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kalai%20Lamia">Kalai Lamia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jilani%20Faouzi"> Jilani Faouzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Measuring and controlling risk is one of the most attractive issues in finance. With the persistence of uncontrolled and erratic stocks movements, volatility is perceived as a barometer of daily fluctuations. An objective measure of this variable seems then needed to control risks and cover those that are considered the most important. Non-linear autoregressive modeling is our first evaluation approach. In particular, we test the presence of “persistence” of conditional variance and the presence of a degree of a leverage effect. In order to resolve for the problem of “asymmetry” in volatility, the retained specifications point to the importance of stocks reactions in response to news. Effects of shocks on volatility highlight also the need to study the “long term” behaviour of conditional variance of stocks returns and articulate the presence of long memory and dependence of time series in the long run. We note that the integrated fractional autoregressive model allows for representing time series that show long-term conditional variance thanks to fractional integration parameters. In order to stop at the dynamics that manage time series, a comparative study of the results of the different models will allow for better understanding volatility structure over the Tunisia stock market, with the aim of accurately predicting fluctuation risks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetry%20volatility" title="asymmetry volatility">asymmetry volatility</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=stylised%20facts" title=" stylised facts"> stylised facts</a>, <a href="https://publications.waset.org/abstracts/search?q=leverage%20effect" title=" leverage effect"> leverage effect</a> </p> <a href="https://publications.waset.org/abstracts/30403/volatility-and-stylized-facts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30403.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">299</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">26</span> Dynamic Software Product Lines for Customer Centric Context Aware Business Process Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bochra%20Khiari">Bochra Khiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Labed"> Lamia Labed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the new digital marketplace, organizations are striving for a proactive position by leveraging the great potential of disruptive technologies to seize the full opportunity of the digital revolution in order to reshape their customer value propositions. New technologies such as big data analytics, which provide prediction of future events based on real-time information, are being integrated into BPM which urges the need for additional core values like capabilities for dynamic adaptation, autonomic behavior, runtime reconfiguration and post-deployment activities to manage unforeseen scenarios at runtime in a situated and changeable context. Dynamic Software Product Lines (DSPL) is an emerging paradigm that supports these runtime variability mechanisms. However, few works exploiting DSPLs principles and techniques in the BPM domain have been proposed so far. In this paper, we propose a conceptual approach DynPL4CBPM, which integrates DSPLs concepts along with the entire related dynamic properties, to the whole BPM lifecycle in order to dynamically adapt business processes according to different context conditions in an individual environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20processes" title="adaptive processes">adaptive processes</a>, <a href="https://publications.waset.org/abstracts/search?q=context%20aware%20business%20process%20management" title=" context aware business process management"> context aware business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20centric%20business%20process%20management" title=" customer centric business process management"> customer centric business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20software%20product%20lines" title=" dynamic software product lines"> dynamic software product lines</a> </p> <a href="https://publications.waset.org/abstracts/81537/dynamic-software-product-lines-for-customer-centric-context-aware-business-process-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81537.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">161</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> Design and Implementation of an Efficient Solar-Powered Pumping System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mennatallah%20M.%20Fouad">Mennatallah M.

The novelty of this work lies in implementing a small-scale experimental setup for a solar-powered water pumping system with a battery back-up system. Cooling and cleaning of the PV panel are implemented to enhance its overall efficiency and output. Moreover, a simulation for a large scale solar-powered pumping system is performed using PVSyst software. Results of the experimental setup show that the PV system with a battery backup proved to be a feasible and viable system to operate the water pumping system. Excess water from the pumping system is used to cool and clean the PV panel and achieved an average percentage increase in the PV output by 21.8%. Simulation results have shown that the system provides adequate output to power the solar-powered system and saves 0.3 tons of CO₂ compared to conventional fossil fuels. It is recommended for hot countries to adopt this system, which would help in decreasing the dependence on the depleting fossil fuels, provide access to electricity to areas where there is no electricity supply and also provide a source of water for crop growth as well as decrease the carbon emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficient%20solar%20pumping" title="efficient solar pumping">efficient solar pumping</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20cleaning" title=" PV cleaning"> PV cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20cooling" title=" PV cooling"> PV cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=PV-operated%20water%20pump" title=" PV-operated water pump"> PV-operated water pump</a> </p> <a href="https://publications.waset.org/abstracts/117406/design-and-implementation-of-an-efficient-solar-powered-pumping-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117406.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">135</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> Rise in Public Interest in COVID-19 Symptoms and the Need for Proper Information: Insights from the Google Trends Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaweriya%20Aftab">Jaweriya Aftab</a>, <a href="https://publications.waset.org/abstracts/search?q=Madho%20Mal"> Madho Mal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamida%20Memon"> Hamida Memon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The first case of coronavirus disease 2019 (COVID-19) in Pakistan was recorded on February 26th, 2020. While the country went through various phases of lockdowns, the importance of proper sensitization campaigns was highlighted by healthcare workers to combat misinformation. Past studies via Google trends analysis have shown a rise in public interest in multiple COVID-19-related symptoms as well as cardiovascular symptoms. As there is a paucity of data related to the trends in Pakistan, we conducted a retrospective analysis to bridge further information. Methods: As per the recommendations from past studies, a Google trend analysis was conducted for various symptoms, including ‘Fever’, ‘Chest Pain’, ‘Shortness of Breath’, and ‘Cough’ between 1st January 2019 to 31st December 2021. The trends in various search results were analyzed and modeled. Results: Our analysis found various rises in public interest in the various symptoms (fever, chest pain, shortness of breath, and cough) that correspond closely to the wave of the virus's spread in the country. Conclusion: Our study confirms similar trends in Pakistan as previously reported in studies from India, USA, and UK, whereby the public interest in various COVID-19 symptoms rose with the number of cases. This further highlights the need for a strong approach to combat misinformation during such a critical period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=covid" title="covid">covid</a>, <a href="https://publications.waset.org/abstracts/search?q=trend" title=" trend"> trend</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=public" title=" public"> public</a> </p> <a href="https://publications.waset.org/abstracts/188288/rise-in-public-interest-in-covid-19-symptoms-and-the-need-for-proper-information-insights-from-the-google-trends-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188288.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">37</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">23</span> Continuous-Time Analysis And Performance Assessment For Digital Control Of High-Frequency Switching Synchronous Dc-Dc Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rihab%20Hamdi">Rihab Hamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Hadri%20Hamida"> Amel Hadri Hamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouafae%20Bennis"> Ouafae Bennis</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakina%20Zerouali"> Sakina Zerouali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper features a performance analysis and robustness assessment of a digitally controlled DC-DC three-cell buck converter associated in parallel, operating in continuous conduction mode (CCM), facing feeding parameters variation and loads disturbance. The control strategy relies on the continuous-time with an averaged modeling technique for high-frequency switching converter. The methodology is to modulate the complete design procedure, in regard to the existence of an instantaneous current operating point for designing the digital closed-loop, to the same continuous-time domain. Moreover, the adopted approach is to include a digital voltage control (DVC) technique, taking an account for digital control delays and sampling effects, which aims at improving efficiency and dynamic response and preventing generally undesired phenomena. The results obtained under load change, input change, and reference change clearly demonstrates an excellent dynamic response of the proposed technique, also as provide stability in any operating conditions, the eﬀectiveness is fast with a smooth tracking of the specified output voltage. Simulations studies in MATLAB/Simulink environment are performed to verify the concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20conduction%20mode" title="continuous conduction mode">continuous conduction mode</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20control" title=" digital control"> digital control</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20multi-cells%20converter" title=" parallel multi-cells converter"> parallel multi-cells converter</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20analysis" title=" performance analysis"> performance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20electronics" title=" power electronics"> power electronics</a> </p> <a href="https://publications.waset.org/abstracts/130482/continuous-time-analysis-and-performance-assessment-for-digital-control-of-high-frequency-switching-synchronous-dc-dc-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130482.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">150</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">22</span> Purification of Bilge Water by Adsorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Atmani">Fatiha Atmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Djellab"> Lamia Djellab</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacera%20Yeddou%20Mezenner"> Nacera Yeddou Mezenner</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Bensaadi"> Zohra Bensaadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Generally, bilge waters can be briefly defined as saline and greasy wastewaters. The oil and grease are mixed with the sea water, which affects many marine species. Bilge water is a complex mixture of various compounds such as solvents, surfactants, fuel, lubricating oils, and hydraulic oils. It is resulted mainly by the leakage from the machinery and fresh water washdowns,which are allowed to drain to the lowest inner part of the ship's hull. There are several physicochemical methods used for bilge water treatment such as biodegradation electrochemical and electro-coagulation/flotation.The research herein presented discusses adsorption as a method to treat bilge water and eggshells were studied as an adsorbent. The influence of operating parameters as contact time, temperature and adsorbent dose (0,2 - 2g/l) on the removal efficiency of Chemical oxygen demand, COD, and turbidity was analyzed. The bilge wastewater used for this study was supplied by Harbour Bouharoune. Chemical oxygen demand removal increased from 26.7% to 68.7% as the adsorbent dose increased from 0.2 to 2 g. The kinetics of adsorption by eggshells were fast, reaching 55 % of the total adsorption capacity in ten minutes (T= 20°C, pH =7.66, m=2g/L). It was found that the turbidity removal efficiency decreased and 95% were achieved at the end of 90 min reaction. The adsorption process was found to be effective for the purification of bilge water and pseudo-second-order kinetic model was fitted for COD removal. <p class="card-text"><strong>Keywords:</strong>
