The natural dyes are friendly to human health and environment. Cochineal (Dactylopius coccus Costa) can be used with other natural dye plants for colouration of silk and wool fabrics. Almost never research works on the dyeing of silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier together. In this study, dyeability of 100 % silk fabric with Dactylopius coccus Costa and Quercus infectoria Olivier was studied. Optimum dyeing parameters were determined by using different concentration of Dactylopius coccus Costa (10%), Quercus infectoria Olivier (0,1,5 and 10%) and mordant salt (0 and 3%). The dyed silk fabrics were examined for their colorimetric and fastness properties. The fabrics were dyed succesfully dark colours with 10 % Dactylopius coccus Costa, 10 % Quercus infectoria Olivier and presence of mordanting after dyeing process (3% mordant salt). The washing and light colour fastness of the dyed fabrics were investigated and adequate results were obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dactylopius%20coccus%20Costa" title="Dactylopius coccus Costa">Dactylopius coccus Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Quercus%20infectoria%20Olivier" title=" Quercus infectoria Olivier"> Quercus infectoria Olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dye" title=" natural dye"> natural dye</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing" title=" dyeing"> dyeing</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fabric" title=" silk fabric"> silk fabric</a> </p> <a href="https://publications.waset.org/abstracts/25583/dyeability-of-silk-fabric-with-dactylopius-coccus-costa-and-quercus-infectoria-olivier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25583.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">597</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">79</span> Melanoma Antigen Proteins Are Involved in DNA Damage Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20de%20Backer">Olivier de Backer</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20Khelfi"> Alexis Khelfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Svensek"> Olivier Svensek</a>, <a href="https://publications.waset.org/abstracts/search?q=Axelle%20Nolmans"> Axelle Nolmans</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Desnoeck"> Dominique Desnoeck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The SMC5-SMC6 complex helps replication and repair of DNA double-strand breaks. Nse1, Nse3 and Nse4 are non-SMC components of the complex in which Nse3 stimulates the E3 ubiquitin ligase activity of Nse1 and is required for recruiting the complex on DNA. In most eukaryotes, Nse3 is a single protein, but in eutherians (placental mammals), it belongs to a large family of proteins called MAGE (Melanoma antigen) that share a conserved domain of about 200 aa known as MHD (Mage homology domain). MAGE assembles specific RING and HECT ubiquitin ligases and determines new substrates for ubiquitination. The MHD is required for the interaction with the cognate E3 ligase. Some MAGEs (referred to as Type I) are exclusively expressed in germ cells of the testis but are often expressed ectopically in cancer cells as the result of epigenetic modifications. The 12 MAGE-A genes belong to this category. Serval MAGE-A proteins could promote tumorigenesis by targeting tumor suppressor proteins (including p53) for ubiquitination and degradation. We showed that depletion of MAGE-A proteins in melanoma cells results in impaired DNA damage response and increased double-strand breaks after exposure to camptothecin. Moreover, it was shown that other actors of the DNA Damage Response were impacted when cells were depleted of MAGEA proteins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage%20response" title="DNA damage response">DNA damage response</a>, <a href="https://publications.waset.org/abstracts/search?q=melanoma" title=" melanoma"> melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=camptothecin" title=" camptothecin"> camptothecin</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20role" title=" new role"> new role</a>, <a href="https://publications.waset.org/abstracts/search?q=MAGEA" title=" MAGEA"> MAGEA</a> </p> <a href="https://publications.waset.org/abstracts/169692/melanoma-antigen-proteins-are-involved-in-dna-damage-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169692.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">101</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">78</span> A New Criterion for Removal of Fouling Deposit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20B%C3%A4cker">D.

The Olea genus contains various species and subspecies, and the only species bearing edible fruit is Olea europaea. The desired issue in this study is to provide the current status of plant cover and especially the training in Olea europaea currently existing in the major centers of the region of Tlemcen. While based on the flora and biometric aspect of this plant germplasm. In order to make an assessment of the phytomass, we made measurements of the four parameters of the aerial part of the taxon: height, diameter, and canopy density to ten feet of the olive tree per station. The floristic analysis shows a certain floristic difference between the different stations. The vegetal formations reflect the biotic and abiotic conditions including climate affecting the ecosystem. Biometric study on the feet of Olea in the six study sites, has led us to conclude that the four measured parameters provides insight on the development or degradation of Olea feet depending on the layout of the stations and the factors environmental. We find that the terrains are havens for these assets. Also the local microclimate (Oued Thalweg) promotes the healthy development of this species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olivier" title="olivier">olivier</a>, <a href="https://publications.waset.org/abstracts/search?q=ecology" title=" ecology"> ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=biometrics" title=" biometrics"> biometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=Tlemcen" title=" Tlemcen"> Tlemcen</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/29444/ecobiological-study-of-olivier-in-the-northern-slopes-of-the-mountains-of-tlemcen-western-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29444.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">296</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">76</span> Sublethal Effects of Entomopathogenic Nematodes and Fungus against the Red Palm Weevil, Rhynchophorus Ferrugineus (Olivier) (Curculionidae: Coleoptera)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Manzoor">M.

Haider</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The invasive Red Palm Weevil (RPW) (Rhynchophorus ferrugineus [Olivier] (Coleoptera: Curculionidae) is one of the most destructive palm pests in the world. Synthetic pesticides are environmentally hazardous pest control strategies being used in the past with emerging need of eco-friendly biological approaches including microbial entomopathogens for RPW management. The sublethal effects of a single entomopathogenic fungus (EPF) Beauveria bassiana (WG-11) (Ascomycota: Hypocreales) and two entomopathogenic nematode (EPN) species Heterorhabditis bacteriophora (Poinar) and Steinernema carpocapsae (Weiser) (Nematoda: Rhabditida) were evaluated in various combinations against laboratory-reared 3rd, 5th and 8th instar larvae of RPW in laboratory assays. Individual and combined effects of both entomopathogens (EP) were observed after the pre-application of B. bassiana fungus at 1-2-week intervals. A number of parameters were measured after the application of sub-lethal doses of EPF such as diet consumption, development, frass production, mortality, and weight gain. Combined treatments were tested for additive and synergistic effects. Synergism was more frequently observed in B. bassiana and S. carpocapsae combined treatments than in B. bassiana and H. bacteriophora combinations. Early instar larvae of RPW were more susceptible than older instars. Synergistic effects were observed in the 3rd and 5th instars exposed to B. bassiana and S. carpocapsae at 0, 7 and 14-day intervals. Whereas, in 8th instar larvae, the synergistic effect was observed only in B. bassiana and S. carpocapsae treatments after 0 and 7 days intervals. EPN treatments decreased pupation, egg hatching and emergence of adults. Lethal effects of nematodes were also observed in all growth stages of R. ferrugineus. Reduced larval weight, increased larval, pre-pupal and pupal duration, reduced adult weight and life span were observed. Sub-lethal concentrations of both entomopathogens induced variations in the different developmental stages and reduced food consumption, frass production, growth, and weight gain. So, on the basis of results, it is concluded that synthetic pesticides should be replaced with environmentally friendly sustainable biopesticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20bacteriophora" title="H. bacteriophora">H. bacteriophora</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20carpocapsae" title=" S. carpocapsae"> S. carpocapsae</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20bassiana" title=" B. bassiana"> B. bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/108739/sublethal-effects-of-entomopathogenic-nematodes-and-fungus-against-the-red-palm-weevil-rhynchophorus-ferrugineus-olivier-curculionidae-coleoptera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108739.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> VaR or TCE: Explaining the Preferences of Regulators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Faroni">Silvia Faroni</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Le%20Courtois"> Olivier Le Courtois</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Ostaszewski"> Krzysztof Ostaszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While a lot of research concentrates on the merits of VaR and TCE, which are the two most classic risk indicators used by financial institutions, little has been written on explaining why regulators favor the choice of VaR or TCE in their set of rules.

Further, this paper provides equivalence rules that explain how a given choice of VaR can be equivalent to a given choice of TCE.

However, very few studies have identified the underlying demographic processes. For short-lived species, like common passerine birds, are these changes generated by changes in adult survival or in fecundity and recruitment? This study tests for an effect of annual climatic conditions (spring and winter) on annual, local adult survival at very large spatial (a country, 252 sites), temporal (25 years) and biological (25 species) scales. The Constant Effort Site ringing has allowed the collection of capture - mark - recapture data for 100 000 adult individuals since 1989, over metropolitan France, thus documenting annual, local survival rates of the most common passerine birds. We specifically developed a set of multi-year, multi-species, multi-site Bayesian models describing variations in local survival and recapture probabilities. This method allows for a statistically powerful hierarchical assessment (global versus species-specific) of the effects of climate variables on survival. A major part of between-year variations in survival rate was common to all species (74% of between-year variance), whereas only 26% of temporal variation was species-specific. Although changing spring climate is commonly invoked as a cause of population size fluctuations, spring climatic anomalies (mean precipitation or temperature for March-August) do not impact adult survival: only 1% of between-year variation of species survival is explained by spring climatic anomalies. However, for sedentary birds, winter climatic anomalies (North Atlantic Oscillation) had a significant, quadratic effect on adult survival, birds surviving less during intermediate years than during more extreme years. For migratory birds, we do not detect an effect of winter climatic anomalies (Sahel Rainfall). We will analyze the life history traits (migration, habitat, thermal range) that could explain a different sensitivity of species to winter climate anomalies. Overall, we conclude that changes in population sizes for passerine birds are unlikely to be the consequences of climate-driven mortality (or emigration) in spring but could be induced by other demographic parameters, like fecundity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20approach" title="Bayesian approach">Bayesian approach</a>, <a href="https://publications.waset.org/abstracts/search?q=capture-recapture" title=" capture-recapture"> capture-recapture</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20anomaly" title=" climate anomaly"> climate anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=constant%20effort%20sites%20scheme" title=" constant effort sites scheme"> constant effort sites scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=passerine" title=" passerine"> passerine</a>, <a href="https://publications.waset.org/abstracts/search?q=seasons" title=" seasons"> seasons</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a> </p> <a href="https://publications.waset.org/abstracts/42791/winter-not-spring-climate-drives-annual-adult-survival-in-common-passerines-a-country-wide-multi-species-modeling-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42791.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">303</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">72</span> The Reasons and the Practical Benefits Behind the Motivation of Businesses to Participate in the Dual Education System (DLS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ainur%20Bulasheva">Ainur Bulasheva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decade, the dual learning system (DLS) has been actively introduced in various industries in Kazakhstan, including both vocational, post-secondary, and higher education levels. It is a relatively new practice-oriented approach to training qualified personnel in Kazakhstan, officially introduced in 2012. Dual learning was integrated from the German vocational education and training system, combining practical training with part-time work in production and training in an educational institution. The policy of DLS has increasingly focused on decreasing youth unemployment and the shortage of mid-level professionals by providing incentives for employers to involve in this system. By participating directly in the educational process, the enterprise strives to train its future personnel to meet fast-changing market demands. This study examines the effectiveness of DLS from the perspective of employers to understand the motivations of businesses to participate (invest) in this program. The human capital theory of Backer, which predicts that employers will invest in training their workers (in our case, dual students) when they expect that the return on investment will be greater than the cost - acts as a starting point. Further extensionists of this theory will be considered to understand investing intentions of businesses. By comparing perceptions of DLS employers and non-dual practices, this study determines the efficiency of promoted training approach for enterprises in the Kazakhstan agri-food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vocational%20and%20technical%20education" title="vocational and technical education">vocational and technical education</a>, <a href="https://publications.waset.org/abstracts/search?q=dualeducation" title=" dualeducation"> dualeducation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20capital%20theory" title=" human capital theory"> human capital theory</a>, <a href="https://publications.waset.org/abstracts/search?q=argi-food%20industry" title=" argi-food industry"> argi-food industry</a> </p> <a href="https://publications.waset.org/abstracts/162382/the-reasons-and-the-practical-benefits-behind-the-motivation-of-businesses-to-participate-in-the-dual-education-system-dls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162382.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">69</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">71</span> Modified Preputial Urethrostomy as a Salvage Procedure in Four Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Giansetto">Thomas Giansetto</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Broux"> Olivier Broux</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9raldine%20Bolen"> Géraldine Bolen</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phanie%20Claeys"> Stéphanie Claeys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To describe a modified preputial urethrostomy in four dogs. Study design: Short case series. Animals: Four male dogs were treated by the modified preputial urethrostomy, three because of urethral stenosis, and one because of severe complications following perineal urethrostomy. Methods: Four dogs were presented for dysuria and urinary obstruction. secondary to urethral stenosis or tear. Obstruction was treated with a modified preputial urethrostomy. Results: Four dogs had resolution of dysuria with a modified preputial urethrostomy without penile amputation. None of the dogs presented signs of dysuria, urinary tract infection, or dermatitis postoperatively. Two dogs showed signs of urinary incontinence 15 days and one month postoperatively.

We show here that the large size and low charge density of POMs, compared to classical ions, are responsible for a peculiar behavior called “super-chaotropy”. This property refers to the strong propensity of nano-ions to adsorb at neutral polar interfaces, via non-specific interactions. It has strong effects on phase transitions in soft matter and can, for example, stabilize colloidal systems such as surfactant foams. A simple way for evaluating and classifying nano-ions, such as POMs, according to their super-chaotropy is proposed here. The super-chaotropic behavior of nano-ions opens many opportunities in separation science, catalysis, and for the design of nanostructured hybrid materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colloids" title="colloids">colloids</a>, <a href="https://publications.waset.org/abstracts/search?q=foams" title=" foams"> foams</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactant" title=" surfactant"> surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20effect" title=" salt effect"> salt effect</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20stability" title=" colloidal stability"> colloidal stability</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-ions" title=" nano-ions"> nano-ions</a> </p> <a href="https://publications.waset.org/abstracts/172708/nanometric-sized-ions-for-colloidal-stabilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172708.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">74</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">69</span> Impact of Network Workload between Virtualization Solutions on a Testbed Environment for Cybersecurity Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Fernagut">Kevin Fernagut</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Flauzac"> Olivier Flauzac</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20M.%20G.%20Robledo"> Erick M.

This paper seeks to assess this with a different approach studying the behavior of a testbed built with tools such as Kernel-Based Virtual Machine (KVM), Linux Containers (LXC) and Docker, by performing stress tests within a platform where students experiment simultaneously with cyber-attacks, and thus observe the impact on the campus network and also find the best solution for cyber-security learning. Interesting outcomes can be found in the literature comparing these technologies. It is, however, difficult to find results of the effects on the global network where experiments are carried out. Our work shows that other physical hosts and the faculty network were impacted while performing these trials. The problems found are discussed, as well as security solutions and the adoption of new network policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=containerization" title="containerization">containerization</a>, <a href="https://publications.waset.org/abstracts/search?q=containers" title=" containers"> containers</a>, <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title=" cybersecurity"> cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=cyberattacks" title=" cyberattacks"> cyberattacks</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=virtualization" title=" virtualization"> virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20machines" title=" virtual machines"> virtual machines</a> </p> <a href="https://publications.waset.org/abstracts/127012/impact-of-network-workload-between-virtualization-solutions-on-a-testbed-environment-for-cybersecurity-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127012.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">149</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">68</span> 2D RF ICP Torch Modelling with Fluid Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Labiod">Mokhtar Labiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Ikhlef"> Nabil Ikhlef</a>, <a href="https://publications.waset.org/abstracts/search?q=Keltoum%20Bouherine"> Keltoum Bouherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Leroy"> Olivier Leroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical model for the radio-frequency (RF) Argon discharge chamber is developed to simulate the low pressure low temperature inductively coupled plasma.

Electric and magnetic fields inside the discharge chamber are evaluated by solving a magnetic vector potential equation. To start with, the equations of the ideal magnetohydrodynamics theory will be presented describing the basic behaviour of magnetically confined plasma and equations are discretized with finite element method in cylindrical coordinates. The discharge chamber is assumed to be axially symmetric and the plasma is treated as a compressible gas. Plasma generation due to ionization is added to the continuity equation.

A strong dependence of the plasma properties on the discharge conditions and the gas temperature is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct-coupled%20model" title="direct-coupled model">direct-coupled model</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic" title=" magnetohydrodynamic"> magnetohydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20torch%20simulation" title=" plasma torch simulation"> plasma torch simulation</a> </p> <a href="https://publications.waset.org/abstracts/38779/2d-rf-icp-torch-modelling-with-fluid-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38779.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">433</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">67</span> An Automated Approach to Consolidate Galileo System Availability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marie%20Bieber">Marie Bieber</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrice%20Cosson"> Fabrice Cosson</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Schmitt"> Olivier Schmitt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Europe's Global Navigation Satellite System, Galileo, provides worldwide positioning and navigation services. The satellites in space are only one part of the Galileo system. An extensive ground infrastructure is essential to oversee the satellites and ensure accurate navigation signals. High reliability and availability of the entire Galileo system are crucial to continuously provide positioning information of high quality to users. Outages are tracked, and operational availability is regularly assessed. A highly flexible and adaptive tool has been developed to automate the Galileo system availability analysis. Not only does it enable a quick availability consolidation, but it also provides first steps towards improving the data quality of maintenance tickets used for the analysis. This includes data import and data preparation, with a focus on processing strings used for classification and identifying faulty data. Furthermore, the tool allows to handle a low amount of data, which is a major constraint when the aim is to provide accurate statistics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=availability" title="availability">availability</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20quality" title=" data quality"> data quality</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20performance" title=" system performance"> system performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Galileo" title=" Galileo"> Galileo</a>, <a href="https://publications.waset.org/abstracts/search?q=aerospace" title=" aerospace"> aerospace</a> </p> <a href="https://publications.waset.org/abstracts/107165/an-automated-approach-to-consolidate-galileo-system-availability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107165.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">167</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">66</span> Heat Transfer Enhancement by Localized Time Varying Thermal Perturbations at Hot and Cold Walls in a Rectangular Differentially Heated Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Thiers">Nicolas Thiers</a>, <a href="https://publications.waset.org/abstracts/search?q=Romain%20Gers"> Romain Gers</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Skurtys"> Olivier Skurtys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study numerically the effect of a thermal perturbation on the heat transfer in a rectangular differentially heated cavity of aspect ratio 4, filled by air.

As well as being large, they can have complex shapes, such as a double horn. For icing simulations, these configurations are currently computed in several steps. The icing step is stopped when the ice shapes become too large, at which point a new mesh has to be created to allow for further CFD and ice growth simulations to be performed. This can be very costly, and is a limiting factor in the simulations that can be performed. A way to avoid the costly human intervention in the re-meshing step of multistep icing computation is to use mesh deformation instead of re-meshing. The aim of the present work is to apply an interpolation method based on Radial Basis Functions (RBF) to transfer deformations from surface mesh to volume mesh. This deformation tool has been developed specifically for icing problems. It is able to deal with localized, sharp and large deformations, unlike the tools traditionally used for more smooth wing deformations. This tool will be presented along with validation on typical two-dimensional icing shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ice%20accretion" title="ice accretion">ice accretion</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation" title=" interpolation"> interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title=" mesh deformation"> mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20functions" title=" radial basis functions"> radial basis functions</a> </p> <a href="https://publications.waset.org/abstracts/59130/an-interpolation-tool-for-data-transfer-in-two-dimensional-ice-accretion-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59130.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">313</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">64</span> Analytical Approach to Study the Uncertainties Related to the Behavior of Structures Submitted to Differential Settlement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elio%20El%20Kahi">Elio El Kahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Khouri"> Michel Khouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Deck"> Olivier Deck</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Rahme"> Pierre Rahme</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasool%20Mehdizadeh"> Rasool Mehdizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent developments in civil engineering create multiple interaction problems between the soil and the structure.

The main purpose of this research is to study the behavior of structures submitted to differential settlement, in order to assess their vulnerability, taking into consideration the different sources of uncertainties. Analytical approach is applied to investigate on one hand the influence of these uncertainties that are related to the soil, and on the other hand the structure stiffness variation with the presence of openings and the movement transmitted between them as related to the origin and shape of the free-field movement.

This awareness has prompted the development of new products more environmentally friendly. Among these products are biocomposite materials reinforced with natural fibers. The main challenge in developing the use of biocomposites in exterior applications is the lack of knowledge about their durability and the evolution of their mechanical and physico-chemical properties in the long term. Few studies have been carried out on the photooxidation of unidirectional (UD) composites based on recycled matrix, which is the aim of this work. For this purpose, UD flax fiber composites based on recycled polypropylene were prepared by thermocompression. An accelerated aging test was carried out using a xenon arc WeatherOmeter. The consequences of UV exposure on the chemical composition and morphology of the surface of composites as well as on their tensile mechanical properties have been reported. The results showed that accelerated aging had a significant effect on the surface of these composites while it had little impact on their mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flax%20fiber" title="flax fiber">flax fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=photooxidation" title=" photooxidation"> photooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=physico-chemical%20properties" title=" physico-chemical properties"> physico-chemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20polypropylene" title=" recycled polypropylene"> recycled polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20properties" title=" tensile properties"> tensile properties</a> </p> <a href="https://publications.waset.org/abstracts/141984/accelerated-ageing-of-unidirectional-flax-fibers-reinforced-recycled-polypropylene-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141984.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">199</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">62</span> U11 Functionalised Luminescent Gold Nanoclusters for Pancreatic Tumor Cells Labelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Regina%20M.%20Chiechio">Regina M.

These applications require control of their delivery and interaction with cells; for this reason, the surface chemistry of Au NCs is essential to determine their interaction with the targeted biological objects. Here we demonstrate their ability as markers of pancreatic tumor cells. By functionalizing the surface of the NCs with a recognition peptite (U11), the nanostructures are able to preferentially bind to pancreatic cancer cells via a receptor (uPAR) overexpressed by these cells. Furthermore, the NCs can mark even the nucleus without the need of fixing the cells. These nanostructures can therefore be used as a non-toxic, multivalent luminescent platform, capable of selectively recognizing tumor cells for bioimaging, drug delivery, and radiosensitization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoclusters" title="gold nanoclusters">gold nanoclusters</a>, <a href="https://publications.waset.org/abstracts/search?q=luminescence" title=" luminescence"> luminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreatic%20cancer" title=" pancreatic cancer"> pancreatic cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20applications" title=" biomedical applications"> biomedical applications</a>, <a href="https://publications.waset.org/abstracts/search?q=bioimaging" title=" bioimaging"> bioimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescent%20probes" title=" fluorescent probes"> fluorescent probes</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a> </p> <a href="https://publications.waset.org/abstracts/146031/u11-functionalised-luminescent-gold-nanoclusters-for-pancreatic-tumor-cells-labelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146031.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">151</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">61</span> A Constructivist Approach and Tool for Autonomous Agent Bottom-up Sequential Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianyong%20Xue">Jianyong Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20L.%20Georgeon"> Olivier L.

These abilities set them apart from even the most advanced autonomous robots. This work seeks to contribute to understand and replicate some of these abilities. We propose the Bottom-up hiErarchical sequential Learning algorithm with Constructivist pAradigm (BEL-CA) to design agents capable of learning autonomously and continuously through interactions. The algorithm implements no assumption about the semantics of input and output data. It does not rely upon a model of the world given a priori in the form of a set of states and transitions as well. Besides, we propose a toolkit to analyze the learning process at run time called GAIT (Generating and Analyzing Interaction Traces). We use GAIT to report and explain the detailed learning process and the structured behaviors that the agent has learned on each decision making. We report an experiment in which the agent learned to successfully interact with its environment and to avoid unfavorable interactions using regularities discovered through interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20development" title="cognitive development">cognitive development</a>, <a href="https://publications.waset.org/abstracts/search?q=constructivist%20learning" title=" constructivist learning"> constructivist learning</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20sequential%20learning" title=" hierarchical sequential learning"> hierarchical sequential learning</a>, <a href="https://publications.waset.org/abstracts/search?q=self-adaptation" title=" self-adaptation"> self-adaptation</a> </p> <a href="https://publications.waset.org/abstracts/129145/a-constructivist-approach-and-tool-for-autonomous-agent-bottom-up-sequential-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129145.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">180</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">60</span> New Approach for Minimizing Wavelength Fragmentation in Wavelength-Routed WDM Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sami%20Baraketi">Sami Baraketi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Marie%20Garcia"> Jean Marie Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Brun"> Olivier Brun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wavelength Division Multiplexing (WDM) is the dominant transport technology used in numerous high capacity backbone networks, based on optical infrastructures. Given the importance of costs (CapEx and OpEx) associated to these networks, resource management is becoming increasingly important, especially how the optical circuits, called “lightpaths”, are routed throughout the network. This requires the use of efficient algorithms which provide routing strategies with the lowest cost. We focus on the lightpath routing and wavelength assignment problem, known as the RWA problem, while optimizing wavelength fragmentation over the network. Wavelength fragmentation poses a serious challenge for network operators since it leads to the misuse of the wavelength spectrum, and then to the refusal of new lightpath requests. In this paper, we first establish a new Integer Linear Program (ILP) for the problem based on a node-link formulation. This formulation is based on a multilayer approach where the original network is decomposed into several network layers, each corresponding to a wavelength. Furthermore, we propose an efficient heuristic for the problem based on a greedy algorithm followed by a post-treatment procedure. The obtained results show that the optimal solution is often reached. We also compare our results with those of other RWA heuristic methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WDM" title="WDM">WDM</a>, <a href="https://publications.waset.org/abstracts/search?q=lightpath" title=" lightpath"> lightpath</a>, <a href="https://publications.waset.org/abstracts/search?q=RWA" title=" RWA"> RWA</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelength%20fragmentation" title=" wavelength fragmentation"> wavelength fragmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20programming" title=" linear programming"> linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristic" title=" heuristic"> heuristic</a> </p> <a href="https://publications.waset.org/abstracts/25101/new-approach-for-minimizing-wavelength-fragmentation-in-wavelength-routed-wdm-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25101.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">527</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">59</span> The Accuracy of an In-House Developed Computer-Assisted Surgery Protocol for Mandibular Micro-Vascular Reconstruction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Spaas">Christophe Spaas</a>, <a href="https://publications.waset.org/abstracts/search?q=Lies%20Pottel"> Lies Pottel</a>, <a href="https://publications.waset.org/abstracts/search?q=Joke%20De%20Ceulaer"> Joke De Ceulaer</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Abeloos"> Johan Abeloos</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Lamoral"> Philippe Lamoral</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20De%20Backer"> Tom De Backer</a>, <a href="https://publications.waset.org/abstracts/search?q=Calix%20De%20Clercq"> Calix De Clercq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We aimed to evaluate the accuracy of an in-house developed low-cost computer-assisted surgery (CAS) protocol for osseous free flap mandibular reconstruction. All patients who underwent primary or secondary mandibular reconstruction with a free (solely or composite) osseous flap, either a fibula free flap or iliac crest free flap, between January 2014 and December 2017 were evaluated. The low-cost protocol consisted out of a virtual surgical planning, a prebend custom reconstruction plate and an individualized free flap positioning guide. The accuracy of the protocol was evaluated through comparison of the postoperative outcome with the 3D virtual planning, based on measurement of the following parameters: intercondylar distance, mandibular angle (axial and sagittal), inner angular distance, anterior-posterior distance, length of the fibular/iliac crest segments and osteotomy angles. A statistical analysis of the obtained values was done. Virtual 3D surgical planning and cutting guide design were performed with Proplan CMF® software (Materialise, Leuven, Belgium) and IPS Gate (KLS Martin, Tuttlingen, Germany). Segmentation of the DICOM data as well as outcome analysis were done with BrainLab iPlan® Software (Brainlab AG, Feldkirchen, Germany). A cost analysis of the protocol was done. Twenty-two patients (11 fibula /11 iliac crest) were included and analyzed. Based on voxel-based registration on the cranial base, 3D virtual planning landmark parameters did not significantly differ from those measured on the actual treatment outcome (p-values >0.05). A cost evaluation of the in-house developed CAS protocol revealed a 1750 euro cost reduction in comparison with a standard CAS protocol with a patient-specific reconstruction plate. Our results indicate that an accurate transfer of the planning with our in-house developed low-cost CAS protocol is feasible at a significant lower cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAD%2FCAM" title="CAD/CAM">CAD/CAM</a>, <a href="https://publications.waset.org/abstracts/search?q=computer-assisted%20surgery" title=" computer-assisted surgery"> computer-assisted surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=low-cost" title=" low-cost"> low-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=mandibular%20reconstruction" title=" mandibular reconstruction"> mandibular reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/93457/the-accuracy-of-an-in-house-developed-computer-assisted-surgery-protocol-for-mandibular-micro-vascular-reconstruction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93457.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">140</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">58</span> Abdominal Pregnancy with a Live Newborn in a Low Resource Setting: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Mulisya">Olivier Mulisya</a>, <a href="https://publications.waset.org/abstracts/search?q=Guelord%20Barasima"> Guelord Barasima</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Mark%20Lugobe"> Henry Mark Lugobe</a>, <a href="https://publications.waset.org/abstracts/search?q=Phil%C3%A9mon%20Matumo"> Philémon Matumo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bienfait%20Mumbere%20Vahwere"> Bienfait Mumbere Vahwere</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilaire%20Mutuka"> Hilaire Mutuka</a>, <a href="https://publications.waset.org/abstracts/search?q=Zawadi%20L%C3%A9ocadie"> Zawadi Léocadie</a>, <a href="https://publications.waset.org/abstracts/search?q=Wesley%20Lumika"> Wesley Lumika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abdominal pregnancy is defined as pregnancy anywhere within the peritoneal cavity, exclusive of tubal, ovarian, or broad ligament locations. It is a rare form of ectopic pregnancy with high morbidity and mortality for both the mother and the fetus. Diagnosis can be frequently missed in most poor-resource settings because of poor antenatal coverage, low socioeconomic status in most of the patients as well as lack of adequate medical resources. Clinical diagnosis can be very difficult and an ultrasound scan is very helpful during the early stages of gestation but can also be disappointing in the later stages. We report a case of a 25-year-old woman with severe abdominal pain not amended with any medication. A clinical picture of shock lead to an emergency laparotomy which confirmed the diagnosis of abdominal pregnancy. The ministry of health in developing countries should make an effort to make routine early ultrasounds accessible to pregnant women, and obstetricians should keep in mind the possibility of ectopic pregnancy, irrespective of the gestational age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abdominal%20pregnancy" title="abdominal pregnancy">abdominal pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=live%20new%20bron" title=" live new bron"> live new bron</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20imaging" title=" ultrasound imaging"> ultrasound imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal%20pain" title=" abdominal pain"> abdominal pain</a> </p> <a href="https://publications.waset.org/abstracts/163482/abdominal-pregnancy-with-a-live-newborn-in-a-low-resource-setting-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163482.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">99</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">57</span> Fund Seekers’ Deception in Peer-to-Peer Lending in Times of COVID</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Mesly">Olivier Mesly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article examines the likelihood of deception on the part of borrowers wishing to obtain credit from institutional or private lenders. In our first study, we identify five explanatory variables that account for nearly forty percent of the propensity to act deceitfully: a poor credit history, debt, risky behavior, and to a much lesser degree, irrational behavior and disconnection from the bundle of needs, goals, and preferences. For the second study, we remodeled the initial questionnaire to adapt it to the needs of institutional bankers and borrowers, especially those that engage in money on-line peer-to-peer lending, a growing business fueled by the COVID pandemic. We find that the three key psychological variables that help to indirectly predict the likelihood of deceitful behaviors and possible default on loan reimbursement, i.e., risky behaviors, ir-rationality, and dis-connection, interact with each other to form a loop. This study presents two benefits: first, we provide evidence that it is to some degree possible to tighten control over lending practices. Second, we offer a pragmatic tool: a questionnaire, that lenders can use or adapt to gauge potential borrowers’ deceit, notably by combining their results with standard hard-data measures of risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bundle%20of%20needs" title="bundle of needs">bundle of needs</a>, <a href="https://publications.waset.org/abstracts/search?q=default" title=" default"> default</a>, <a href="https://publications.waset.org/abstracts/search?q=debt" title=" debt"> debt</a>, <a href="https://publications.waset.org/abstracts/search?q=deception" title=" deception"> deception</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=peer-to-peer%20lending" title=" peer-to-peer lending"> peer-to-peer lending</a> </p> <a href="https://publications.waset.org/abstracts/146408/fund-seekers-deception-in-peer-to-peer-lending-in-times-of-covid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146408.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">132</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">56</span> Nonlinear Analysis of Postural Sway in Multiple Sclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hua%20Cao">Hua Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Peyrodie"> Laurent Peyrodie</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Agnani"> Olivier Agnani</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecile%20Donze"> Cecile Donze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple sclerosis (MS) is a disease, which affects the central nervous system, and causes balance problem. In clinical, this disorder is usually evaluated using static posturography. Some linear or nonlinear measures, extracted from the posturographic data (i.e. center of pressure, COP) recorded during a balance test, has been used to analyze postural control of MS patients. In this study, the trend (TREND) and the sample entropy (SampEn), two nonlinear parameters were chosen to investigate their relationships with the expanded disability status scale (EDSS) score. Forty volunteers with different EDSS scores participated in our experiments with eyes open (EO) and closed (EC). TREND and two types of SampEn (SampEn1 and SampEn2) were calculated for each combined COP’s position signal. The results have shown that TREND had a weak negative correlation to EDSS while SampEn2 had a strong positive correlation to EDSS. Compared to TREND and SampEn1, SampEn2 showed a better significant correlation to EDSS and an ability to discriminate the MS patients in the EC case. In addition, the outcome of the study suggests that the multi-dimensional nonlinear analysis could provide some information about the impact of disability progression in MS on dynamics of the COP data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title=" multiple sclerosis"> multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=postural%20sway" title=" postural sway"> postural sway</a> </p> <a href="https://publications.waset.org/abstracts/40541/nonlinear-analysis-of-postural-sway-in-multiple-sclerosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40541.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">338</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">55</span> Determining a Bilingualism Index: Evidence From Lebanese Control Bilinguals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20Kassir">Rania Kassir</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Dos%20Santos"> Christophe Dos Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Halim%20Abboud"> Halim Abboud</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Godefroy"> Olivier Godefroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability to communicate in at least two different languages is shared by a growing number of humans. Recently, many researchers have been studying the elderly bilingual population around the world in neuroscience, and yet, until today there’s no accurate nor universal measure or methodology used to examine bilingualism across these studies which constitute a real challenge for results generalization. This study contributes to the quest of a multidimensional bilingualism index and language proficiency literature by investigating a new bilingualism index from a reliable subjective questionnaire the Language Experience and Proficiency Questionnaire (LEAP-Q), multi-linguistic tests, and a diverse bilingual population all featured in one analysis and one index. One hundred Lebanese subjects aged between 55 and 92 years old divided into three different bilingualism subgroups (Arabic prominent, balanced, and French prominent) were recruited and underwent the LEAP-Q with a set of linguistic and cognitive tests. The analysis of the collected data led to the creation of a robust bilingualism index from speaking and oral understanding scores that underline specifically bilingualism subtype according to cutoffs scored. The practice implications of this index, particularly its use within bilingual populations, are addressed in the conclusion of this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title="bilingualism">bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20dominance" title=" language dominance"> language dominance</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingualism%20index" title=" bilingualism index"> bilingualism index</a>, <a href="https://publications.waset.org/abstracts/search?q=balanced%20bilingualism" title=" balanced bilingualism"> balanced bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20first%20language" title=" Arabic first language"> Arabic first language</a>, <a href="https://publications.waset.org/abstracts/search?q=Lebanese" title=" Lebanese"> Lebanese</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic-French%20bilingualism" title=" Arabic-French bilingualism"> Arabic-French bilingualism</a> </p> <a href="https://publications.waset.org/abstracts/147829/determining-a-bilingualism-index-evidence-from-lebanese-control-bilinguals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147829.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">128</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">54</span> Effects of Voltage Pulse Characteristics on Some Performance Parameters of LiₓCoO₂-based Resistive Switching Memory Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Van%20Son%20Nguyen">Van Son Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Van%20Huy%20Mai"> Van Huy Mai</a>, <a href="https://publications.waset.org/abstracts/search?q=Alec%20Moradpour"> Alec Moradpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Auban%20Senzier"> Pascale Auban Senzier</a>, <a href="https://publications.waset.org/abstracts/search?q=Claude%20Pasquier"> Claude Pasquier</a>, <a href="https://publications.waset.org/abstracts/search?q=Kang%20Wang"> Kang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre-Antoine%20Albouy"> Pierre-Antoine Albouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20J.%20Rozenberg"> Marcelo J.

To face the limitations of existing Flash memory cells (endurance, downscaling, rapidity…), new approaches are emerging, among them resistive switching memories (Re-RAM). In this work, we analysed the behaviour of LixCoO2 oxide thin films in electrode/film/electrode devices. Preliminary results have been obtained concerning the influence of bias pulses characteristics (duration, value) on some performance parameters, such as endurance and resistance ratio (ROFF/RON). Besides, Conducting Probe Atomic Force Microscopy (CP-AFM) characterizations of the devices have been carried out to better understand some causes of performance failure, and thus help optimizing the switching performance of such devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non%20volatile%20resistive%20memories" title="non volatile resistive memories">non volatile resistive memories</a>, <a href="https://publications.waset.org/abstracts/search?q=resistive%20switching" title=" resistive switching"> resistive switching</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=endurance" title=" endurance"> endurance</a> </p> <a href="https://publications.waset.org/abstracts/65064/effects-of-voltage-pulse-characteristics-on-some-performance-parameters-of-licoo2-based-resistive-switching-memory-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65064.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">611</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">53</span> Readiness Assessment to Implement Net-Zero Energy Building Program of Government Buildings in the Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patrick%20T.%20Aquino">Patrick T.

The building sector, as one of the most energy-intensive sectors, shall conform to the energy-conserving design to reduce the use of energy. The concept of Net-Zero Energy Building (NZEB), and its definitions promote to improve energy efficiency of the buildings. The PDOE partnered with Meralco Power Academy to survey and conduct focus group discussions to establish the readiness into NZE-aspiring buildings of government entities. This paper outlines important NZEB principles, best practices from other countries, issues and gaps relating to energy management program, and the recommendations on the development of a framework for NZEB under government building in the Philippines. Results revealed the limitation on specific data to establish a baseline building energy efficiency performance index and significant energy uses; the need to update the Guidelines for Energy Conservation Design of Buildings, including NZEB definition and requirements; appropriate enabling infrastructures and programs to transition government buildings into NZE-aspiring buildings to Nearly Zero Energy Buildings by 2050. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NZEB" title="NZEB">NZEB</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=buildings" title=" buildings"> buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippines" title=" Philippines"> Philippines</a> </p> <a href="https://publications.waset.org/abstracts/172274/readiness-assessment-to-implement-net-zero-energy-building-program-of-government-buildings-in-the-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172274.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Application of the Quantile Regression Approach to the Heterogeneity of the Fine Wine Prices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles-Olivier%20Am%C3%A9d%C3%A9e-Manesme">Charles-Olivier Amédée-Manesme</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Faye"> Benoit Faye</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Le%20Fur"> Eric Le Fur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the heterogeneity of the Bordeaux Legends 50 wine market price segment is addressed. For this purpose, quantile regression is applied – with market segmentation based on wine bottle price quantile – and the hedonic price of wine attributes is computed for various price segments of the market. The approach is applied to a major privately held data set which consists of approximately 30,000 transactions over the 2003–2014 period. The findings suggest that the relative hedonic prices of several wine attributes differ significantly among deciles. In particular, the elasticity coefficient of the expert ratings shows strong variation among prices. If - as suggested in the literature - expert ratings have a positive influence on wine price on average, they have a clearly decreasing impact over the quantiles. Finally, the lower the wine price, the higher the potential for price appreciation over time. Other variables such as chateaux or vintage are also shown to vary across the distribution of wine prices. While enhancing our understanding of the complex market dynamics that underlie Bordeaux wines’ price, this research provides empirical evidence that the QR approach adequately captures heterogeneity among wine price ranges, which simultaneously applies to wine stock, vintage and auctions’ house. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hedonics" title="hedonics">hedonics</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20segmentation" title=" market segmentation"> market segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20regression" title=" quantile regression"> quantile regression</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=wine%20economics" title=" wine economics"> wine economics</a> </p> <a href="https://publications.waset.org/abstracts/70068/application-of-the-quantile-regression-approach-to-the-heterogeneity-of-the-fine-wine-prices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70068.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">340</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> Development of an Energy Independant DC Building Demonstrator for Insulated Island Site</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivia%20Bory%20Devisme">Olivia Bory Devisme</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Genon-Catalot"> Denis Genon-Catalot</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Alicalapa"> Frederic Alicalapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre-Olivier%20Lucas%20De%20Peslouan"> Pierre-Olivier Lucas De Peslouan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Pierre%20Chabriat"> Jean-Pierre Chabriat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of climate change, it is essential that island territories gain energy autonomy. Currently mostly dependent on fossil fuels, the island of Reunion lo- cated in the Indian Ocean nevertheless has a high potential for solar energy. As the market for photovoltaic panels has been growing in recent years, the issues of energy losses linked to the multiple conversions from direct current to alternating current are emerging. In order to quantify these advantages and disadvantages by a comparative study, this document present the measurements carried out on a direct current test bench, particularly for lighting, ventilation, air condi- tioning and office equipment for the tertiary sector. All equipment is supplied with DC power from energy produced by photovoltaic panels. A weather sta- tion, environmental indoor sensors, and drivers are also used to control energy. Self-consumption is encouraged in order to manage different priorities between user consumption and energy storage in a lithium iron phosphate battery. The measurements are compared to a conventional electrical architecture (DC-AC- DC) for energy consumption, equipment overheating, cost, and life cycle analysis. <p
