The mathematical model mimics the ignition process in a commercial spark-plug when a high voltage is applied to the plug terminals. A longitudinal unidimensional Cartesian domain is chosen for the simulation region. Energy and mass transfer are considered for a macroscopic fluid representation, while energy transfer in molecular collisions and chemical reactions are contemplated at microscopic level. The macroscopic model is represented by a set of uncoupled partial differential equations. Microscopic effects are studied within a discrete model for electronic and molecular collisions in the frame of ZDPlasKin, a plasma modeling numerical tool. The BOLSIG+ solver is employed in solving the electronic Boltzmann equation. An operator splitting technique is used to separate microscopic and macroscopic models. The simulation gas is a mixture of atomic Argon neutral, excited and ionized. Spatial and temporal evolution of such species and temperature are presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20discharge" title=" electronic discharge"> electronic discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=ignition" title=" ignition"> ignition</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20plug" title=" spark plug"> spark plug</a> </p> <a href="https://publications.waset.org/abstracts/91943/simulation-of-1d-dielectric-barrier-discharge-in-argon-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91943.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">92</span> First Digit Lucas, Fibonacci and Benford Number in Financial Statement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teguh%20Sugiarto">Teguh Sugiarto</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Mohamadian%20Amiri"> Amir Mohamadian Amiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: This study aims to explore if there is fraud in the company's financial report distribution using the number first digit Lucas, Fibonacci and Benford.

There are two types of Chebyshev polynomials, a Chebyshev polynomial of first kind and a Chebyshev polynomial of second kind. Chebyshev polynomial of second kind can be derived from the Chebyshev polynomial of first kind. Chebyshev polynomial is a polynomial of degree n and satisfies a second order homogenous differential equation. We consider the difference equations which are related with Chebyshev, Fibonacci and Lucas polynomias.

Lucas Based El-Gamal Cryptosystem in the Elliptic Curve group over finite field was exposed mathematically to the GCD attack using GCD and Dickson polynomial.

The proposed method detects moving objects such as pedestrians, the other vehicles and some obstacles at the front-side of the host vehicle, and it can provide the warning to the driver. Motion vectors are obtained by using pyramidal Lucas-Kanade optical flow, and some outliers are eliminated by comparing the amplitude of each vector with the pre-defined threshold value. The background model is obtained by calculating the mean and the variance of the amplitude of recent motion vectors in the rectangular shaped local region called the cell. The model is applied as the reference to classify motion vectors of moving objects and those of background. Motion vectors are clustered to rectangular regions by using the unsupervised clustering K-means algorithm. Labeling method is applied to label groups which is close to each other, using by distance between each center points of rectangular. Through the simulations tested on four kinds of scenarios such as approaching motorbike, vehicle, and pedestrians to host vehicle, we prove that the proposed is simple but efficient for moving object detection in parking lots. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moving%20object%20detection" title="moving object detection">moving object detection</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20scene" title=" dynamic scene"> dynamic scene</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20flow" title=" optical flow"> optical flow</a>, <a href="https://publications.waset.org/abstracts/search?q=pyramidal%20optical%20flow" title=" pyramidal optical flow"> pyramidal optical flow</a> </p> <a href="https://publications.waset.org/abstracts/50958/pyramidal-lucas-kanade-optical-flow-based-moving-object-detection-in-dynamic-scenes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50958.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">349</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">87</span> Adaptive Motion Compensated Spatial Temporal Filter of Colonoscopy Video </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nidhal%20Azawi">Nidhal Azawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Colonoscopy procedure is widely used in the world to detect an abnormality. Early diagnosis can help to heal many patients. Because of the unavoidable artifacts that exist in colon images, doctors cannot detect a colon surface precisely. The purpose of this work is to improve the visual quality of colonoscopy videos to provide better information for physicians by removing some artifacts. This work complements a series of work consisting of three previously published papers. In this paper, Optic flow is used for motion compensation, and then consecutive images are aligned/registered to integrate some information to create a new image that has or reveals more information than the original one. Colon images have been classified into informative and noninformative images by using a deep neural network. Then, two different strategies were used to treat informative and noninformative images. Informative images were treated by using Lucas Kanade (LK) with an adaptive temporal mean/median filter, whereas noninformative images are treated by using Lucas Kanade with a derivative of Gaussian (LKDOG) with adaptive temporal median images. A comparison result showed that this work achieved better results than that results in the state- of- the- art strategies for the same degraded colon images data set, which consists of 1000 images. The new proposed algorithm reduced the error alignment by about a factor of 0.3 with a 100% successfully image alignment ratio. In conclusion, this algorithm achieved better results than the state-of-the-art approaches in case of enhancing the informative images as shown in the results section; also, it succeeded to convert the non-informative images that have very few details/no details because of the blurriness/out of focus or because of the specular highlight dominate significant amount of an image to informative images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optic%20flow" title="optic flow">optic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=colonoscopy" title=" colonoscopy"> colonoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=artifacts" title=" artifacts"> artifacts</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20temporal%20filter" title=" spatial temporal filter"> spatial temporal filter</a> </p> <a href="https://publications.waset.org/abstracts/131333/adaptive-motion-compensated-spatial-temporal-filter-of-colonoscopy-video" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131333.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">113</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">86</span> Time and Cost Prediction Models for Language Classification Over a Large Corpus on Spark</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jairson%20Barbosa%20Rodrigues">Jairson Barbosa Rodrigues</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Romero%20Martins%20Maciel"> Paulo Romero Martins Maciel</a>, <a href="https://publications.waset.org/abstracts/search?q=Germano%20Crispim%20Vasconcelos"> Germano Crispim Vasconcelos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an investigation of the performance impacts regarding the variation of five factors (input data size, node number, cores, memory, and disks) when applying a distributed implementation of Naïve Bayes for text classification of a large Corpus on the Spark big data processing framework. Problem: The algorithm's performance depends on multiple factors, and knowing before-hand the effects of each factor becomes especially critical as hardware is priced by time slice in cloud environments. Objectives: To explain the functional relationship between factors and performance and to develop linear predictor models for time and cost. Methods: the solid statistical principles of Design of Experiments (DoE), particularly the randomized two-level fractional factorial design with replications. This research involved 48 real clusters with different hardware arrangements. The metrics were analyzed using linear models for screening, ranking, and measurement of each factor's impact. Results: Our findings include prediction models and show some non-intuitive results about the small influence of cores and the neutrality of memory and disks on total execution time, and the non-significant impact of data input scale on costs, although notably impacts the execution time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiments" title=" design of experiments"> design of experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20machine%20learning" title=" distributed machine learning"> distributed machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title=" natural language processing"> natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=spark" title=" spark"> spark</a> </p> <a href="https://publications.waset.org/abstracts/128727/time-and-cost-prediction-models-for-language-classification-over-a-large-corpus-on-spark" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128727.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">120</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">85</span> Photoelectrochemical Water Splitting from Earth-Abundant CuO Thin Film Photocathode: Enhancing Performance and Photo-Stability through Deposition of Overlayers </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wilman%20Septina">Wilman Septina</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajiv%20R.%20Prabhakar"> Rajiv R.

It is a p-type semiconductor with a band gap of around 1.5 eV, absorbing a significant portion of the solar spectrum. One of the main challenges in using CuO as solar absorber in an aqueous system is its tendency towards photocorrosion, generating Cu2O and metallic Cu. Although there have been several reports of CuO as a photocathode for hydrogen production, it is unclear how much of the observed current actually corresponds to H2 evolution, as the inevitability of photocorrosion is usually not addressed. In this research, we investigated the effect of the deposition of overlayers onto CuO thin films for the purpose of enhancing its photostability as well as performance for water splitting applications. CuO thin film was fabricated by galvanic electrodeposition of metallic copper onto gold-coated FTO substrates, followed by annealing in air at 600 °C. Photoelectrochemical measurement of the bare CuO film using 1 M phosphate buffer (pH 6.9) under simulated AM 1.5 sunlight showed a current density of ca. 1.5 mA cm-2 (at 0.4 VRHE), which photocorroded to Cu metal upon prolonged illumination. This photocorrosion could be suppressed by deposition of 50 nm-thick TiO2, deposited by atomic layer deposition. In addition, we found that insertion of an n-type CdS layer, deposited by chemical bath deposition, between the CuO and TiO2 layers was able to enhance significantly the photocurrent compared to without the CdS layer. A photocurrent of over 2 mA cm-2 (at 0 VRHE) was observed using the photocathode stack FTO/Au/CuO/CdS/TiO2/Pt. Structural, electrochemical, and photostability characterizations of the photocathode as well as results on various overlayers will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CuO" title="CuO">CuO</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=photoelectrochemical" title=" photoelectrochemical"> photoelectrochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=photostability" title=" photostability"> photostability</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20splitting" title=" water splitting"> water splitting</a> </p> <a href="https://publications.waset.org/abstracts/54277/photoelectrochemical-water-splitting-from-earth-abundant-cuo-thin-film-photocathode-enhancing-performance-and-photo-stability-through-deposition-of-overlayers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54277.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">224</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> New Approach for Melanoma Skin Cancer Controled Releasing Drugs for Neutron Capture Therapy: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Bernardes%20Naves">Lucas Bernardes Naves</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Almeida"> Luis Almeida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper includes a review concerning the use of some composites including poly(lactide-co-glycolide) (PGLA), zeolite and Gadopentetic acid (Gd-DTPA) loaded chitosan nanoparticles (Gd-nanoCPs) in order to establish a new alternative for the treatment of Melanoma Skin Cancer.

This approach facilitates the visualisation of the relative benefits of each, and it provides a potential baseline for the development of a plan of action that is rooted in quantitative evaluation. Emissions reductions are converted to potential de-escalation of global average temperature. A comprehensive plan is then presented which shows the potential benefits all the way out to year 2100. A target temperature de-escalation of 2oC was selected, but the plan shows a benefit of only 1.225oC. This latter disappointing result is in spite of new and powerful technologies introduced into the equation. These include nuclear fusion and alternative nuclear fission processes. Current technologies such as wind, solar and electric vehicles show surprisingly small constributions to the whole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=drawdown" title=" drawdown"> drawdown</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/158394/a-quantitative-plan-for-drawing-down-emissions-to-attenuate-climate-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158394.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">131</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> Identifying Critical Success Factors for Data Quality Management through a Delphi Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Paula%20Santos">Maria Paula Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lucas"> Ana Lucas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organizations support their operations and decision making on the data they have at their disposal, so the quality of these data is remarkably important and Data Quality (DQ) is currently a relevant issue, the literature being unanimous in pointing out that poor DQ can result in large costs for organizations.

It has a few colored variations used as jewelry, like Aquamarine (blueish), Emerald (green) and Heliodor (yellow). The color of each variation depends on the dopant that is naturally present in the crystal lattice. In this work, Heliodor pellets of 5 mm diameter and 1 mm thickness have been produced and investigated using thermoluminescence (TL) to evaluate its potential for use as gamma ray’s dosimeter. The results show that the pellets exhibited a prominent TL peak at 205 °C that grows linearly with dose when irradiated from 1 Gy to 1000 Gy. A comparison has been made between powdered and sintered dosimeters. The results show that sintered pellets have higher sensitivity than powder dosimeter. The TL response of this mineral is satisfactory for radiation dosimetry applications in the studied dose range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dosimetry" title="dosimetry">dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=beryl" title=" beryl"> beryl</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20rays" title=" gamma rays"> gamma rays</a>, <a href="https://publications.waset.org/abstracts/search?q=sintered%20pellets" title=" sintered pellets"> sintered pellets</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20material" title=" new material"> new material</a> </p> <a href="https://publications.waset.org/abstracts/157397/radiation-dosimetry-using-sintered-pellets-of-yellow-beryl-heliodor-crystals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157397.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">96</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">77</span> An Efficient Fundamental Matrix Estimation for Moving Object Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yeongyu%20Choi">Yeongyu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20H.%20Park"> Ju H.

This paper adds to this developing area by considering the relationships between the concepts of tactus, metric imposition, polymeter and rhythmic parallax in the Meshuggah composition “Do Not Look Down”. By considering an architectonic rhythmic framework within “Do Not Look Down” as the controlling organisation mechanism, an exploration of the interaction between distinct rhythmic layers and the composition’s formal segmentation and harmony (as riffs), reveals a pervasive structural misalignment between these elements. By exhibiting how Meshuggah’s manipulations of rhythmic complexities deliberately blur structural boundaries, creating misalignments in a flat approach to temporal partitioning (Nieto 2014), rhythmic characteristics of Meshuggah and the genre of Djent are exposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypermeter" title="hypermeter">hypermeter</a>, <a href="https://publications.waset.org/abstracts/search?q=rhythmic%20parallax" title=" rhythmic parallax"> rhythmic parallax</a>, <a href="https://publications.waset.org/abstracts/search?q=meshuggah" title=" meshuggah"> meshuggah</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20partitioning" title=" temporal partitioning"> temporal partitioning</a> </p> <a href="https://publications.waset.org/abstracts/166951/rhythmic-prioritisation-as-a-means-of-compositional-organisation-analysing-meshuggahs-do-not-look-down" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166951.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">78</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> Portuguese Influence on Minas Gerais Dessert Culinary During Brazil Colonization Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvania%20M.%20P.%20Silva">Silvania M.

Through a historical survey, visits to mining towns known for their sweet culture and material collected in these places, we present the protagonists of this journey of flavors: the Portuguese cake makers (boleiras), who brought the knowledge, ingredients, and the dream of a better life in the crowded mines of gold and opportunities, helping to form a new Minas Gerais knowledge with their delicacies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sweets%20from%20portugal" title="sweets from portugal">sweets from portugal</a>, <a href="https://publications.waset.org/abstracts/search?q=convent%20sweets" title=" convent sweets"> convent sweets</a>, <a href="https://publications.waset.org/abstracts/search?q=minas%20gerais" title=" minas gerais"> minas gerais</a>, <a href="https://publications.waset.org/abstracts/search?q=brazil" title=" brazil"> brazil</a> </p> <a href="https://publications.waset.org/abstracts/147936/portuguese-influence-on-minas-gerais-dessert-culinary-during-brazil-colonization-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147936.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">74</span> Probabilistic and Stochastic Analysis of a Retaining Wall for C-Φ Soil Backfill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Lu%C3%ADs%20Brasil%20Cavalcante">André Luís Brasil Cavalcante</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Felix%20Rodriguez%20Rebolledo"> Juan Felix Rodriguez Rebolledo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Parreira%20de%20Faria%20Borges"> Lucas Parreira de Faria Borges</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A methodology for the probabilistic analysis of active earth pressure on retaining wall for c-Φ soil backfill is described in this paper. The Rosenblueth point estimate method is used to measure the failure probability of a gravity retaining wall. The basic principle of this methodology is to use two point estimates, i.e., the standard deviation and the mean value, to examine a variable in the safety analysis. The simplicity of this framework assures to its wide application. For the calculation is required 2ⁿ repetitions during the analysis, since the system is governed by n variables. In this study, a probabilistic model based on the Rosenblueth approach for the computation of the overturning probability of failure of a retaining wall is presented. The obtained results have shown the advantages of this kind of models in comparison with the deterministic solution. In a relatively easy way, the uncertainty on the wall and fill parameters are taken into account, and some practical results can be obtained for the retaining structure design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title="retaining wall">retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20earth%20pressure" title=" active earth pressure"> active earth pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=backfill" title=" backfill"> backfill</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20analysis" title=" probabilistic analysis"> probabilistic analysis</a> </p> <a href="https://publications.waset.org/abstracts/52396/probabilistic-and-stochastic-analysis-of-a-retaining-wall-for-c-f-soil-backfill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52396.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">418</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">73</span> Wicking and Evaporation of Liquids in Knitted Fabrics: Analytic Solution of Capillary Rise Restrained by Gravity and Evaporation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20S.%20Achour">N.

The goal is to model the effect of gravity and evaporation on wicking using simple analytical expressions and investigate the influence of fabrics geometrical parameters, such as porosity and thickness on evaporation impact on maximum reachable height values. The results show that fabric properties have a significant influence on evaporation effect. In this paper, an experimental study of determining water kinetics from different knitted fabrics were gravimetrically investigated permitting the measure of the mass and the height of liquid rising in fabrics in various atmospheric conditions. From these measurements, characteristic pore parameters (capillary radius and permeability) can be determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evaporation" title="evaporation">evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20study" title=" experimental study"> experimental study</a>, <a href="https://publications.waset.org/abstracts/search?q=geometrical%20parameters" title=" geometrical parameters"> geometrical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20knitted%20fabrics" title=" porous knitted fabrics"> porous knitted fabrics</a>, <a href="https://publications.waset.org/abstracts/search?q=wicking" title=" wicking"> wicking</a> </p> <a href="https://publications.waset.org/abstracts/27286/wicking-and-evaporation-of-liquids-in-knitted-fabrics-analytic-solution-of-capillary-rise-restrained-by-gravity-and-evaporation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27286.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">582</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> Alternative Housing Solutions in Southern California</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Scott%20Kelting">Scott Kelting</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Nozick"> Lucas Nozick</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The perpetually growing population and economy within the United States necessitates building construction of all types. Increased building generates environmental concerns, and rightfully so. This industry accounts for approximately 4% of the total GDP in the United States while creating around two-thirds of the material waste annually. The green building movement is certainly gaining popularity in both application and recognition through entities such as the United States Green Building Council (USGBC) and their LEED program; however, builders are also producing their ideas. Alternative housing solutions that include pre-fabricated building components and shipping container homes are making great strides in the residential construction industry, and will certainly play an important role in the future. This paper will compare the cost and schedule of modular, panelized and shipping container homes to traditional stick frame home construction in the Greater Los Angeles Metropolitan Area and recommend the best application for each option. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost" title="cost">cost</a>, <a href="https://publications.waset.org/abstracts/search?q=prefabricated" title=" prefabricated"> prefabricated</a>, <a href="https://publications.waset.org/abstracts/search?q=schedule" title=" schedule"> schedule</a>, <a href="https://publications.waset.org/abstracts/search?q=shipping%20container" title=" shipping container"> shipping container</a>, <a href="https://publications.waset.org/abstracts/search?q=stick%20framed" title=" stick framed"> stick framed</a> </p> <a href="https://publications.waset.org/abstracts/65814/alternative-housing-solutions-in-southern-california" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65814.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">305</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> Analysis of the Acoustic Performance of Vertical Internal Seals with Pet Wool as NBR 15.575-4NO Green Towers Building-DF</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Aerre">Lucas Aerre</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallesson%20Faria"> Wallesson Faria</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Pimentel"> Roberto Pimentel</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Santos"> Juliana Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An extremely disturbing and irritating element in the lives of people and organizations is the noise, the consequences that can bring us has a lot of connection with human health as well as financial and economic aspects. In order to improve the efficiency of buildings in Brazil in general, a performance standard was created, NBR 15.575 in which all buildings are seen in a more systemic and peculiar way, while following the requirements of the standard. The acoustic performance present in these buildings is one such requirement. Based on this, the present work was elaborated with the objective of evaluating through acoustic measurements the acoustic performance of vertical internal fences that are under the incidence of aerial noise of a building in the city of Brasilia-DF. A short theoretical basis is made and soon after the procedures of measurement are described through the control method established by the standard, and its results are evaluated according to the parameters of the same. The measurement performed between rooms of the same unit, presented a standardized sound pressure level difference (D nT, w) equal to 40 dB, thus being classified within the minimum performance required by the standard in question. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airborne%20noise" title="airborne noise">airborne noise</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20standard" title=" performance standard"> performance standard</a>, <a href="https://publications.waset.org/abstracts/search?q=soundproofing" title=" soundproofing"> soundproofing</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20seal" title=" vertical seal"> vertical seal</a> </p> <a href="https://publications.waset.org/abstracts/67389/analysis-of-the-acoustic-performance-of-vertical-internal-seals-with-pet-wool-as-nbr-15575-4no-green-towers-building-df" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67389.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">297</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">70</span> Gender Diversity on the Board and Asymmetry Information: An Empirical Analysis for Spanish Listed Firms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Abad">David Abad</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Encarnaci%C3%B3n%20Lucas-P%C3%A9rez"> M.

Using a Spanish sample for the period 2004-2009, proxies for information asymmetry estimated from high-frequency data, and a system GMM methodology, we find that the gender diversity on boards is negative associated with the level of information asymmetry in the stock market.

Amongst these nutrients required for proper plant productivity are nitrogen, phosphorus and potassium (NPK). Due to factors like leaching, nutrients uptake by plants, soil erosion and evaporation, these elements tend to be in low quantity and the need to replenish them arises. But these replenishment of soil nutrients cannot be done without a timely soil test to enable farmers to know the amount of each element in short quantity and evaluate the amount required to be added. Though wet soil analysis is good but it comes with a lot of challenges ranging from soil test gargets availability to the technical knowledge of how to conduct such soil test by the common farmer. Internet of things test kit was developed to fill in the gaps created by wet soil analysis, as it can test for N, P, K, soil temperature and soil moisture in a given soil at the time of test. In this implementation, sample test was carried out within 0.2 hectares of land divided into smaller plots. The kits perform adequately well as the range of values obtained across the segments were within a very close range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Internet%20of%20Things" title="Internet of Things">Internet of Things</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20nutrients" title=" soil nutrients"> soil nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20kit" title=" test kit"> test kit</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20temperature" title=" soil temperature"> soil temperature</a> </p> <a href="https://publications.waset.org/abstracts/174522/development-of-an-iot-system-for-smart-crop-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174522.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">77</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> Deepnic, A Method to Transform Each Variable into Image for Deep Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20J.%20M.">Nguyen J.

We propose a new method, DeepNic, to transform each variable of a tabular dataset into an image where each pixel represents a set of conditions that allow the variable to make an error-free prediction. The contrast of each pixel is proportional to its prediction performance and the color of each pixel corresponds to a sub-family of NICs. NICs are probabilities that depend on the number of inputs to each neuron and the range of coefficients of the inputs. Each variable can therefore be expressed as a function of a matrix of 2 vectors corresponding to an image whose pixels express predictive capabilities. Our objective is to transform each variable of tabular data into images into an image that can be analysed by CNNs, unlike other methods which use all the variables to construct an image. We analyse the NIC information of each variable and express it as a function of the number of neurons and the range of coefficients used. The predictive value and the category of the NIC are expressed by the contrast and the color of the pixel. We have developed a pipeline to implement this technology and have successfully applied it to genomic expressions on an Affymetrix chip. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tabular%20data" title="tabular data">tabular data</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=perfect%20trees" title=" perfect trees"> perfect trees</a>, <a href="https://publications.waset.org/abstracts/search?q=NICS" title=" NICS"> NICS</a> </p> <a href="https://publications.waset.org/abstracts/152479/deepnic-a-method-to-transform-each-variable-into-image-for-deep-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152479.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">90</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> Promoting Stem Education and a Cosmic Perspective by Using 21st Century Science of Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohan%20Roberts">Rohan Roberts</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this project was to collaborate with a group of high-functioning, more-able students (aged 15-18) to promote STEM Education and a love for science by bringing a cosmic perspective into the classroom and high school environment. This was done using 21st century science of learning, a focus on the latest research on Neuroeducation, and modern pedagogical methods based on Howard Gardner's theory of Multiple Intelligences, Bill Lucas’ theory of New Smarts, and Sir Ken Robinson’s recommendations on encouraging creativity. The result was an increased sense of passion, excitement, and wonder about science in general, and about the marvels of space and the universe in particular. In addition to numerous unique and innovative science-based initiatives, clubs, workshops, and science trips, this project also saw a marked rise in student-teacher collaboration in science learning and in student engagement with the general public through the press, social media, and community-based initiatives.

These are materials designated as standard SMC, Advanced Sheet Molding Compounds (A-SMC), Low-Density SMC (LD-SMC) and etc. In this study, testing methods have been performed to compare the mechanical responses and damage phenomena of SMC, LD-SMC, and A-SMC under quasi-static and high strain rate tensile tests. The paper also aims at investigating the effect of an initial pre-damage induced by fatigue on the tensile dynamic behavior of A-SMC. In the case of SMCs and A-SMCs, whatever the fibers orientation and applied strain rate are, the first observed phenomenon of damage corresponds to decohesion of the fiber-matrix interface which is followed by coalescence and multiplication of these micro-cracks and their propagations. For LD-SMCs, damage mechanisms depend on the presence of Hollow Glass Microspheres (HGM) and fibers orientation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SMC" title="SMC">SMC</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheet%20Molding%20Compound" title=" Sheet Molding Compound"> Sheet Molding Compound</a>, <a href="https://publications.waset.org/abstracts/search?q=LD-SMC" title=" LD-SMC"> LD-SMC</a>, <a href="https://publications.waset.org/abstracts/search?q=Low-Density%20SMC" title=" Low-Density SMC"> Low-Density SMC</a>, <a href="https://publications.waset.org/abstracts/search?q=A-SMC" title=" A-SMC"> A-SMC</a>, <a href="https://publications.waset.org/abstracts/search?q=Advanced%20Sheet%20Molding%20Compounds" title=" Advanced Sheet Molding Compounds"> Advanced Sheet Molding Compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=HGM" title=" HGM"> HGM</a>, <a href="https://publications.waset.org/abstracts/search?q=Hollow%20Glass%20Microspheres" title=" Hollow Glass Microspheres"> Hollow Glass Microspheres</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a> </p> <a href="https://publications.waset.org/abstracts/100208/multi-scale-damage-and-mechanical-behavior-of-sheet-molding-compound-composites-subjected-to-fatigue-dynamic-and-post-fatigue-dynamic-loadings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100208.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">211</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">65</span> Development of Biotechnological Emulsion Based on Bullfrog (Rana catesbeiana Shaw) Oil: A Preliminary Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lourena%20M.%20Ver%C3%ADssimo">Lourena M.

The BO was extracted at 80ºC and analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). The critical Hydrophilic-Lipophilic Balance (HLBc) Assay of the BO was performed through BO, Tween® 20, Span® 80 and deionized water mixtures using an Ultra-Turrax® and determined using dynamic light scattering, pH, electrical conductivity and creaming rate. Then, a pseudoternary phase diagram (PPD) was constructed by water titration. The GC/MS analysis of BO suggested Methyl Oleate (9.26%) as major compound. The HLBc was 12.1, wherein the correspondent emulsion showed a pH of 4.83±1.29, electrical conductivity of 103.65 µS, creaming rate of 2.51±0.54%, droplet size of 207.07±8.31 nm and polydispersity index of 0.212±0.005. The PPD showed different formulations characterized as O/W emulsions. Thus, the PPD proved to be a useful tool to produce BO emulsions, in which their constituents may vary within the range of the desired system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bullfrog%20%28Rana%20catesbeiana%20Shaw%29%20oil" title="bullfrog (Rana catesbeiana Shaw) oil">bullfrog (Rana catesbeiana Shaw) oil</a>, <a href="https://publications.waset.org/abstracts/search?q=emulsion%20production" title=" emulsion production"> emulsion production</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophilic-lipophilic%20balance" title=" hydrophilic-lipophilic balance"> hydrophilic-lipophilic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography%2Fmass%20spectrometry%20analysis" title=" gas chromatography/mass spectrometry analysis"> gas chromatography/mass spectrometry analysis</a> </p> <a href="https://publications.waset.org/abstracts/11772/development-of-biotechnological-emulsion-based-on-bullfrog-rana-catesbeiana-shaw-oil-a-preliminary-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11772.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">507</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> Success Measurement in Corporate Venturing: Integrating Three Decades of Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maurice%20Steinhoff">Maurice Steinhoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucas%20Costantino"> Lucas Costantino</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominik%20Kanbach"> Dominik Kanbach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Measurement approaches to corporate venturing (CV) success are highly diverse in the extant literature. Furthermore, these approaches rarely build on each other, making it difficult to derive comparable conclusions about CV outcomes. Employing a systematic literature review of three decades of research, the objective of this study is to provide transparency and structure in the broad field of CV research. Subsequently, the paper examines 28 studies in detail, resulting in two main contributions to the research field. First, three structural dimensions of measurement approaches are derived from the studies in the sample, namely, “level of analysis” (parent, program, and venture levels), “measurement perspective” (objective, subjective, and mixed measurement), and “locus of opportunity” (internal, external, and general CV activities). Second, an integrated overview of nine unique clusters structures the different measurement approaches. These clusters allow to encapsulate measurement approaches, but also make visible the approaches’ heterogeneity, as well as specific measurement items. Thereby, the study contributes to CV research by revealing and reconciling the variety of CV success-measurement approaches. The study also provides relevant insights for practitioners, by making transparent the various approaches to measuring the success of CV activities and presenting a list of 114 concrete and distinct measurement items. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20venturing" title="corporate venturing">corporate
