Accurate power consumption prediction allows utilities to organize in advance their resources or to execute Demand Response strategies more effectively, which enables several features such as higher sustainability, better quality of service, and affordable electricity tariffs. It is easy yet effective to apply Load Forecasting at larger geographic scale, i.e. Smart Micro Grids, wherein the lower available grid flexibility makes accurate prediction more critical in Demand Response applications. This paper analyses the application of short-term load forecasting in a concrete scenario, proposed within the EU-funded GreenCom project, which collect load data from single loads and households belonging to a Smart Micro Grid. Three short-term load forecasting techniques, i.e. linear regression, artificial neural networks, and radial basis function network, are considered, compared, and evaluated through absolute forecast errors and training time. The influence of weather conditions in Load Forecasting is also evaluated. A new definition of Gain is introduced in this paper, which innovatively serves as an indicator of short-term prediction capabilities of time spam consistency. Two models, 24- and 1-hour-ahead forecasting, are built to comprehensively compare these three techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short-term%20load%20forecasting" title="short-term load forecasting">short-term load forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20micro%20grid" title=" smart micro grid"> smart micro grid</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20regression" title=" linear regression"> linear regression</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20function%20network" title=" radial basis function network"> radial basis function network</a>, <a href="https://publications.waset.org/abstracts/search?q=gain" title=" gain"> gain</a> </p> <a href="https://publications.waset.org/abstracts/19621/evaluation-of-short-term-load-forecasting-techniques-applied-for-smart-micro-grids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19621.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">468</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">3272</span> The Integrated Strategy of Maintenance with a Scientific Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Meckawey">Mahmoud Meckawey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research is dealing with one of the most important aspects of maintenance fields, that is Maintenance Strategy. It's the branch which concerns the concepts and the schematic thoughts in how to manage maintenance and how to deal with the defects in the engineering products (buildings, machines, etc.) in general. Through the papers we will act with the followings: i) The Engineering Product & the Technical Systems: When we act with the maintenance process, in a strategic view, we act with an (engineering product) which consists of multi integrated systems. In fact, there is no engineering product with only one system. We will discuss and explain this topic, through which we will derivate a developed definition for the maintenance process. ii) The factors or basis of the functionality efficiency: That is the main factors affect the functional efficiency of the systems and the engineering products, then by this way we can give a technical definition of defects and how they occur. iii) The legality of occurrence of defects (Legal defects and Illegal defects): with which we assume that all the factors of the functionality efficiency been applied, and then we will discuss the results. iv) The Guarantee, the Functional Span Age and the Technical surplus concepts: In the complementation with the above topic, and associated with the Reliability theorems, where we act with the Probability of Failure state, with which we almost interest with the design stages, that is to check and adapt the design of the elements. But in Maintainability we act in a different way as we act with the actual state of the systems. So, we act with the rest of the story that means we have to act with the complementary part of the probability of failure term which refers to the actual surplus of the functionality for the systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering%20product%20and%20technical%20systems" title="engineering product and technical systems">engineering product and technical systems</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20span%20age" title=" functional span age"> functional span age</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20and%20illegal%20defects" title=" legal and illegal defects"> legal and illegal defects</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20and%20functional%20surplus" title=" technical and functional surplus"> technical and functional surplus</a> </p> <a href="https://publications.waset.org/abstracts/78716/the-integrated-strategy-of-maintenance-with-a-scientific-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78716.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">475</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">3271</span> Study of Biodegradable Composite Materials Based on Polylactic Acid and Vegetal Reinforcements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Hannachi">Manel Hannachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Nechiche"> Mustapha Nechiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Azem"> Said Azem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on biodegradable materials made from Poly-lactic acid (PLA) and vegetal reinforcements. Three materials are developed from PLA, as a matrix, and : (i) olive kernels (OK); (ii) alfa (α) short fibers and (iii) OK+ α mixture, as reinforcements. After processing of PLA pellets and olive kernels in powder and alfa stems in short fibers, three mixtures, namely PLA-OK, PLA-α, and PLA-OK-α are prepared and homogenized in Turbula®. These mixtures are then compacted at 180°C under 10 MPa during 15 mn. Scanning Electron Microscopy (SEM) examinations show that PLA matrix adheres at surface of all reinforcements and the dispersion of these ones in matrix is good. X-ray diffraction (XRD) analyses highlight an increase of PLA inter-reticular distances, especially for the PLA-OK case. These results are explained by the dissociation of some molecules derived from reinforcements followed by diffusion of the released atoms in the structure of PLA. This is consistent with Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) analysis results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alfa%20short%20fibers" title="alfa short fibers">alfa short fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20composite" title=" biodegradable composite"> biodegradable composite</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20kernels" title=" olive kernels"> olive kernels</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-lactic%20acid" title=" poly-lactic acid"> poly-lactic acid</a> </p> <a href="https://publications.waset.org/abstracts/85801/study-of-biodegradable-composite-materials-based-on-polylactic-acid-and-vegetal-reinforcements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85801.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3270</span> Sustainable Upgrade of Existing Heritage Infrastructure - Strengthening and Rehabilitation of The LH Ford Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vince%20Scolaro">Vince Scolaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakshman%20Prasad"> Lakshman Prasad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ted%20Polley"> Ted Polley</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjivan%20Deshpande"> Sanjivan Deshpande</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The LH Ford Bridge, built in the 1960s, comprises 28 spans, is 800m long and crosses the Macquarie River at Dubbo, NSW. The main bridge spans comprise three spans with a 63m center span (25m drop-in section) supported by halving joints from the main cantilevers and back spans of 28m. The main bridge spans were built using complex construction staging (the first of this type in NSW). They comprise twin precast boxes, in-situ reinforced concrete infills, and cantilevered outriggers stressed both longitudinally and transversely. Since construction, this bridge has undergone significantly increased design vehicle loads and showed signs of excessive shrinkage and creep leading to significant sagging of the centre span with evidence of previous failure and remediation of the halving joints. A comprehensive load rating assessment was undertaken taking account of the original complex construction staging. Deficiencies identified included inadequate capacity of the halving joints, failure of the bearings at the halving joints, inadequate shear capacity of the girder webs and inadequate girder flexural capacity to carry B-Double design vehicles. A unique strengthening system comprising two new piers (under each of the halving joints), new bearings and installation of external prestressing to the soffit of both drop-in-span and back spans was adopted. A portion of the dead load had to be transferred from the superstructure to the new piers via innovative soft/stiff bearing combinations to reduce new locked-in stresses resulting from the new pier supports. Significant temporary works comprised a precast concrete shell beam forming the pile cap/pier structure, addition of a temporary suspended scaffold (without overstressing the existing superstructure) and the installation of jacking stays for new bearing top and bottom plates. This paper presents how this existing historic and socially important bridge was strengthened and updated to increase its design life without the need for replacement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strengthening" title="strengthening">strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=creep" title=" creep"> creep</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=box%20girder" title=" box girder"> box girder</a> </p> <a href="https://publications.waset.org/abstracts/177574/sustainable-upgrade-of-existing-heritage-infrastructure-strengthening-and-rehabilitation-of-the-lh-ford-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177574.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">139</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">3269</span> The Contribution of SMES to Improve the Transient Stability of Multimachine Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Ch%C3%A9rif">N.

Thus, to have a balance between production and consumption, it is necessary at first to increase the number of power plants, lines and transformers, which implies an increase in cost and environmental degradation. As a result, it is now important to have mesh networks and working close to the limits of stability in order to meet these new requirements. The transient stability studies involve large disturbances such as short circuits, loss of work or production group. The consequence of these defects can be very serious, and can even lead to the complete collapse of the network. This work focuses on the regulation means that networks can help to keep their stability when submitted to strong disturbances. The magnetic energy storage-based superconductor (SMES) comprises a superconducting coil short-circuited on it self. When such a system is connected to a power grid is able to inject or absorb the active and reactive power. This system can be used to improve the stability of power systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short-circuit" title="short-circuit">short-circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20oscillations" title=" power oscillations"> power oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=multiband%20PSS" title=" multiband PSS"> multiband PSS</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a>, <a href="https://publications.waset.org/abstracts/search?q=SMES" title=" SMES"> SMES</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20stability" title=" transient stability"> transient stability</a> </p> <a href="https://publications.waset.org/abstracts/1367/the-contribution-of-smes-to-improve-the-transient-stability-of-multimachine-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1367.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">457</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">3268</span> Prediction of the Lateral Bearing Capacity of Short Piles in Clayey Soils Using Imperialist Competitive Algorithm-Based Artificial Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Dinarvand">Reza Dinarvand</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Sadeghian"> Mahdi Sadeghian</a>, <a href="https://publications.waset.org/abstracts/search?q=Somaye%20Sadeghian"> Somaye Sadeghian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prediction of the ultimate bearing capacity of piles (Qu) is one of the basic issues in geotechnical engineering. So far, several methods have been used to estimate Qu, including the recently developed artificial intelligence methods. In recent years, optimization algorithms have been used to minimize artificial network errors, such as colony algorithms, genetic algorithms, imperialist competitive algorithms, and so on. In the present research, artificial neural networks based on colonial competition algorithm (ANN-ICA) were used, and their results were compared with other methods. The results of laboratory tests of short piles in clayey soils with parameters such as pile diameter, pile buried length, eccentricity of load and undrained shear resistance of soil were used for modeling and evaluation. The results showed that ICA-based artificial neural networks predicted lateral bearing capacity of short piles with a correlation coefficient of 0.9865 for training data and 0.975 for test data. Furthermore, the results of the model indicated the superiority of ICA-based artificial neural networks compared to back-propagation artificial neural networks as well as the Broms and Hansen methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=clayey%20soil" title=" clayey soil"> clayey soil</a>, <a href="https://publications.waset.org/abstracts/search?q=imperialist%20competition%20algorithm" title=" imperialist competition algorithm"> imperialist competition algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20bearing%20capacity" title=" lateral bearing capacity"> lateral bearing capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20pile" title=" short pile"> short pile</a> </p> <a href="https://publications.waset.org/abstracts/104881/prediction-of-the-lateral-bearing-capacity-of-short-piles-in-clayey-soils-using-imperialist-competitive-algorithm-based-artificial-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104881.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">152</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">3267</span> Prosodic Transfer in Foreign Language Learning: A Phonetic Crosscheck of Intonation and F₀ Range between Italian and German Native and Non-Native Speakers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Violetta%20Cataldo">Violetta Cataldo</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Savy"> Renata Savy</a>, <a href="https://publications.waset.org/abstracts/search?q=Simona%20Sbranna"> Simona Sbranna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Foreign Language Learning (FLL) is characterised by prosodic transfer phenomena regarding pitch accents placement, intonation patterns, and pitch range excursion from the learners’ mother tongue to their Foreign Language (FL) which suggests that the gradual development of general linguistic competence in FL does not imply an equally correspondent improvement of the prosodic competence. Topic: The present study aims to monitor the development of prosodic competence of learners of Italian and German throughout the FLL process. The primary object of this study is to investigate the intonational features and the f₀ range excursion of Italian and German from a cross-linguistic perspective; analyses of native speakers’ productions point out the differences between this pair of languages and provide models for the Target Language (TL). A following crosscheck compares the L2 productions in Italian and German by non-native speakers to the Target Language models, in order to verify the occurrence of prosodic interference phenomena, i.e., type, degree, and modalities. Methodology: The subjects of the research are university students belonging to two groups: Italian native speakers learning German as FL and German native speakers learning Italian as FL. Both of them have been divided into three subgroups according to the FL proficiency level (beginners, intermediate, advanced). The dataset consists of wh-questions placed in situational contexts uttered in both speakers’ L1 and FL. Using a phonetic approach, analyses have considered three domains of intonational contours (Initial Profile, Nuclear Accent, and Terminal Contour) and two dimensions of the f₀ range parameter (span and level), which provide a basis for comparison between L1 and L2 productions. Findings: Results highlight a strong presence of prosodic transfer phenomena affecting L2 productions in the majority of both Italian and German learners, irrespective of their FL proficiency level; the transfer concerns all the three domains of the contour taken into account, although with different modalities and characteristics. Currently, L2 productions of German learners show a pitch span compression on the domain of the Terminal Contour compared to their L1 towards the TL; furthermore, German learners tend to use lower pitch range values in deviation from their L1 when improving their general linguistic competence in Italian FL proficiency level. Results regarding pitch range span and level in L2 productions by Italian learners are still in progress. At present, they show a similar tendency to expand the pitch span and to raise the pitch level, which also reveals a deviation from the L1 possibly in the direction of German TL. Conclusion: Intonational features seem to be 'resistant' parameters to which learners appear not to be particularly sensitive. By contrast, they show a certain sensitiveness to FL pitch range dimensions. Making clear which the most resistant and the most sensitive parameters are when learning FL prosody could lay groundwork for the development of prosodic trainings thanks to which learners could finally acquire a clear and natural pronunciation and intonation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20learning" title="foreign language learning">foreign language learning</a>, <a href="https://publications.waset.org/abstracts/search?q=German" title=" German"> German</a>, <a href="https://publications.waset.org/abstracts/search?q=Italian" title=" Italian"> Italian</a>, <a href="https://publications.waset.org/abstracts/search?q=L2%20prosody" title=" L2 prosody"> L2 prosody</a>, <a href="https://publications.waset.org/abstracts/search?q=pitch%20range" title=" pitch range"> pitch range</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer" title=" transfer"> transfer</a> </p> <a href="https://publications.waset.org/abstracts/93831/prosodic-transfer-in-foreign-language-learning-a-phonetic-crosscheck-of-intonation-and-f0-range-between-italian-and-german-native-and-non-native-speakers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93831.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">286</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">3266</span> Effect of Site Amplification on Seismic Safety Evaluation of Flyover Pier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Raihan%20Mukhlis">Mohammad Raihan Mukhlis</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdur%20Rahman%20Bhuiyan"> M.

Being situated in a seismically active region, seismic safety evaluation of flyovers is essential for seismic risk reduction. Effects of site amplification on seismic safety evaluation of flyover piers are the main concern of this study. In this regard, failure mode, lateral strength and displacement ductility of piers of a typical multi-span simply supported flyover have been evaluated by Japan Road Association (JRA) recommended guidelines, with and without considering site amplification. Ultimate flexural strengths of piers have been computed using the pushover analysis results. Shear capacity of piers has been calculated using the guidelines of JRA. Lateral strengths have been determined depending on the failure modes of the piers. Displacement ductility of piers has been computed using yield and ultimate displacements of the piers obtained from the pushover analysis results. Selected earthquake time history is used in seismic safety evaluation of the flyover piers. Finally, the ductility design method is used to conduct the seismic safety evaluation of the piers with and without considering site amplification. From the numerical results, it has been revealed that the effects of site amplification on seismic safety evaluation of bridge structures should be carefully taken into account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement%20ductility" title="displacement ductility">displacement ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=flyover%20pier" title=" flyover pier"> flyover pier</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20strength" title=" lateral strength"> lateral strength</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20evaluation" title=" safety evaluation"> safety evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20amplification" title=" site amplification"> site amplification</a> </p> <a href="https://publications.waset.org/abstracts/98971/effect-of-site-amplification-on-seismic-safety-evaluation-of-flyover-pier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98971.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">170</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">3265</span> Comparison of Solar Radiation Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Behar">O.

This traditional analysis does not take into account the quality of modeling and linearity. In our analysis we have tested 22 solar radiation models that are capable to provide instantaneous direct and global radiation at any given location Worldwide. We introduce a new indicator, which we named Global Accuracy Indicator (GAI) to examine the linear relationship between the measured and predicted values and the quality of modeling in addition to long and short terms performance. Note that the quality of model has been represented by the T-Statistical test, the model linearity has been given by the correlation coefficient and the long and short term performance have been respectively known by the MBE and RMSE. An important founding of this research is that the use GAI allows avoiding default validation when using traditional methodology that might results in erroneous prediction of solar power conversion systems performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation%20model" title="solar radiation model">solar radiation model</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20model" title=" parametric model"> parametric model</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20analysis" title=" performance analysis"> performance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Global%20Accuracy%20Indicator%20%28GAI%29" title=" Global Accuracy Indicator (GAI)"> Global Accuracy Indicator (GAI)</a> </p> <a href="https://publications.waset.org/abstracts/9242/comparison-of-solar-radiation-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9242.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3264</span> Computer-Aided Teaching of Transformers for Undergraduates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roopali%20Dogra"> Roopali Dogra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Aggarwal"> Puneet Aggarwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the era of technological advancement, use of computer technology has become inevitable. Hence it has become the need of the hour to integrate software methods in engineering curriculum as a part to boost pedagogy techniques. Simulations software is a great help to graduates of disciplines such as electrical engineering. Since electrical engineering deals with high voltages and heavy instruments, extra care must be taken while operating with them. The viable solution would be to have appropriate control. The appropriate control could be well designed if engineers have knowledge of kind of waveforms associated with the system. Though these waveforms can be plotted manually, but it consumes a lot of time. Hence aid of simulation helps to understand steady state of system and resulting in better performance. In this paper computer, aided teaching of transformer is carried out using MATLAB/Simulink. The test carried out on a transformer includes open circuit test and short circuit respectively. The respective parameters of transformer are then calculated using the values obtained from open circuit and short circuit test respectively using Simulink. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20aided%20teaching" title="computer aided teaching">computer aided teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20circuit%20test" title=" open circuit test"> open circuit test</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20circuit%20test" title=" short circuit test"> short circuit test</a>, <a href="https://publications.waset.org/abstracts/search?q=simulink" title=" simulink"> simulink</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a> </p> <a href="https://publications.waset.org/abstracts/73486/computer-aided-teaching-of-transformers-for-undergraduates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73486.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">374</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">3263</span> Preparation on Sentimental Analysis on Social Media Comments with Bidirectional Long Short-Term Memory Gated Recurrent Unit and Model Glove in Portuguese</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Alfredo%20Mendoza">Leonardo Alfredo Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Munoz"> Cristian Munoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Aurelio%20Pacheco"> Marco Aurelio Pacheco</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoela%20Kohler"> Manoela Kohler</a>, <a href="https://publications.waset.org/abstracts/search?q=Evelyn%20%20Batista"> Evelyn Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Moura"> Rodrigo Moura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural Language Processing (NLP) techniques are increasingly more powerful to be able to interpret the feelings and reactions of a person to a product or service.

Although recurrent networks such as long short-term memory networks help to overcome this problem, achieving high text classification performance is a challenging problem. Convolutional recurrent networks that combine the advantages of long short-term memory networks and convolutional neural networks can be useful for text classification performance improvements.

Evaluating a student’s output require wide array of domains. Scoring the work is often a critical task. Several attempts in the past few years to create an automated writing assessment software but only have received negative results from teachers and students alike due to unreliability in scoring, does not provide feedback and others. The study aims to create an application that will be able to check short-answer questions which incorporate information extraction. Information extraction is a subfield of Natural Language Processing (NLP) where a chunk of text (technically known as unstructured text) is being broken down to gather necessary bits of data and/or keywords (structured text) to be further analyzed or rather be utilized by query tools. The proposed system shall be able to extract keywords or phrases from the individual’s answers to match it into a corpora of words (as defined by the instructor), which shall be the basis of evaluation of the individual’s answer. The proposed system shall also enable the teacher to provide feedback and re-evaluate the output of the student for some writing elements in which the computer cannot fully evaluate such as creativity and logic. Teachers can formulate, design, and check short answer questions efficiently by defining keywords or phrases as parameters by assigning weights for checking answers. With the proposed system, teacher’s time in checking and evaluating students output shall be lessened, thus, making the teacher more productive and easier. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20extraction" title="information extraction">information extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=short-answer%20question" title=" short-answer question"> short-answer question</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=application" title=" application"> application</a> </p> <a href="https://publications.waset.org/abstracts/62355/information-extraction-for-short-answer-question-for-the-university-of-the-cordilleras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62355.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">428</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">3260</span> Flexural Performance of the Sandwich Structures Having Aluminum Foam Core with Different Thicknesses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Kara">Emre Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Fatih%20Geylan"> Ahmet Fatih Geylan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kadir%20Ko%C3%A7"> Kadir Koç</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eura%20Karakuzu"> Şura Karakuzu</a>, <a href="https://publications.waset.org/abstracts/search?q=Metehan%20Demir"> Metehan Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20Aykul"> Halil Aykul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structures obtained with the use of sandwich technologies combine low weight with high energy absorbing capacity and load carrying capacity. Hence, there is a growing and markedly interest in the use of sandwiches with aluminium foam core because of very good properties such as flexural rigidity and energy absorption capability. The static (bending and penetration) and dynamic (dynamic bending and low velocity impact) tests were already performed on the aluminum foam cored sandwiches with different types of outer skins by some of the authors. In the current investigation, the static three-point bending tests were carried out on the sandwiches with aluminum foam core and glass fiber reinforced polymer (GFRP) skins at different values of support span distances (L= 55, 70, 80, 125 mm) aiming the analyses of their flexural performance. The influence of the core thickness and the GFRP skin type was reported in terms of peak load, energy absorption capacity and energy efficiency. For this purpose, the skins with two different types of fabrics ([0°/90°] cross ply E-Glass Woven and [0°/90°] cross ply S-Glass Woven which have same thickness value of 1.5 mm) and the aluminum foam core with two different thicknesses (h=10 and 15 mm) were bonded with a commercial polyurethane based flexible adhesive in order to combine the composite sandwich panels. The GFRP skins fabricated via Vacuum Assisted Resin Transfer Molding (VARTM) technique used in the study can be easily bonded to the aluminum foam core and it is possible to configure the base materials (skin, adhesive and core), fiber angle orientation and number of layers for a specific application. The main results of the bending tests are: force-displacement curves, peak force values, absorbed energy, energy efficiency, collapse mechanisms and the effect of the support span length and core thickness. The results of the experimental study showed that the sandwich with the skins made of S-Glass Woven fabrics and with the thicker foam core presented higher mechanical values such as load carrying and energy absorption capacities. The increment of the support span distance generated the decrease of the mechanical values for each type of panels, as expected, because of the inverse proportion between the force and span length. The most common failure types of the sandwiches are debonding of the upper or lower skin and the core shear. The obtained results have particular importance for applications that require lightweight structures with a high capacity of energy dissipation, such as the transport industry (automotive, aerospace, shipbuilding and marine industry), where the problems of collision and crash have increased in the last years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20foam" title="aluminum foam">aluminum foam</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20panel" title=" composite panel"> composite panel</a>, <a href="https://publications.waset.org/abstracts/search?q=flexure" title=" flexure"> flexure</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20application" title=" transport application"> transport application</a> </p> <a href="https://publications.waset.org/abstracts/27534/flexural-performance-of-the-sandwich-structures-having-aluminum-foam-core-with-different-thicknesses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27534.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">3259</span> Short-Term Energy Efficiency Decay and Risk Analysis of Ground Source Heat Pump System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tu%20Shuyang">Tu Shuyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Xu"> Zhang Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhou%20Xiang"> Zhou Xiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this paper is to investigate the effect of short-term heat exchange decay of ground heat exchanger (GHE) on the ground source heat pump (GSHP) energy efficiency and capacity. A resistance-capacitance (RC) model was developed and adopted to simulate the transient characteristics of the ground thermal condition and heat exchange. The capacity change of the GSHP was linked to the inlet and outlet water temperature by polynomial fitting according to measured parameters given by heat pump manufacturers. Thus, the model, which combined the heat exchange decay with the capacity change, reflected the energy efficiency decay of the whole system. A case of GSHP system was analyzed by the model, and the result showed that there was risk that the GSHP might not meet the load demand because of the efficiency decay in a short-term operation.

And the result shows that changing the cross section girder shape of the composite section to inverted T, with same section area, increased the ultimate load by 5% when compared with same section of rectangular shape girder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reactive%20powder%20concrete" title="reactive powder concrete">reactive powder concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=RPC" title=" RPC"> RPC</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20concrete" title=" hybrid concrete"> hybrid concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20section" title=" composite section"> composite section</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20girder" title=" RC girder"> RC girder</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20slab" title=" RC slab"> RC slab</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20connecters" title=" shear connecters"> shear connecters</a>, <a href="https://publications.waset.org/abstracts/search?q=inverted%20T%20section" title=" inverted T section"> inverted T section</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20reinforcment" title=" shear reinforcment"> shear reinforcment</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20span%20over%20effective%20depth" title=" shear span over effective depth"> shear span over effective depth</a> </p> <a href="https://publications.waset.org/abstracts/23769/behavior-of-composite-construction-precast-reactive-powder-rc-girder-and-ordinary-rc-deck-slab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23769.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">362</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">3257</span> The Channels through Which Energy Tax Can Affect Economic Growth: Panel Data Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Hassan">Mahmoud Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Walid%20Oueslati"> Walid Oueslati</a>, <a href="https://publications.waset.org/abstracts/search?q=Damien%20Rousseliere"> Damien Rousseliere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the channels through which energy taxes may affect economic growth, using a simultaneous equations model for a balanced panel data of 31 OECD countries over the 1994–2013 period. The empirical results reveal a negative impact of energy taxes on physical investment in the short and long term. This impact is negatively sensitive to the existence and level of public debt. Additionally, the results show that energy taxes have an indirect effect on human capital through their impact on polluting emissions. The taxes on energy products are able to reduce both the flux and the stock of polluting emissions that have a negative impact on human capital skills in the short and long term.

Using the discrete wavelet transform (DWT) for the current Park’s vector modulus (CPVM) analysis, the inter-turn short-circuit faults diagnosis can be achieved. This method is based on the decomposition of the CPVM signal, where wavelet approximation and detail coefficients of this signal have been extracted. The energy evaluation of a known bandwidth detail permits to define a fault severity factor (FSF). This method has been tested through the simulation of an induction motor using a mathematical model based on the winding-function approach. Simulation, as well as experimental, results show the effectiveness of the used method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Induction%20Motors%20%28IMs%29" title="Induction Motors (IMs)">Induction Motors (IMs)</a>, <a href="https://publications.waset.org/abstracts/search?q=Inter-turn%20Short-Circuits%20Diagnosis" title=" Inter-turn Short-Circuits Diagnosis"> Inter-turn Short-Circuits Diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Discrete%20Wavelet%20Transform%20%28DWT%29" title=" Discrete Wavelet Transform (DWT)"> Discrete Wavelet Transform (DWT)</a>, <a href="https://publications.waset.org/abstracts/search?q=Current%20Park%E2%80%99s%20Vector%20Modulus%20%28CPVM%29" title=" Current Park’s Vector Modulus (CPVM)"> Current Park’s Vector Modulus (CPVM)</a> </p> <a href="https://publications.waset.org/abstracts/22006/stator-short-circuits-fault-diagnosis-in-induction-motors-using-extended-parks-vector-approach-through-the-discrete-wavelet-transform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22006.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">563</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">3255</span> Translation in Greek and Psychometric Properties of the 9-Item Internet Gaming Disorder Scale-Short Form (IGDS9-Sf)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aspasia%20Simpsi">Aspasia Simpsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to translate into Greek and then validate the psychometric properties of the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) (Pontes & Griffiths, 2015). This is the first short standardized psychometric tool to assess Internet Gaming Disorder (IGD) according to the DSM-V nine clinical criteria and among the most frequently examined. The translation of the test was done through the process of back-translation. To gain a better insight into the psychometric properties of this test, the questionnaire included demographic questions and the Greek version of the Internet Addiction Test (Young, 1998). The participants of the study were 241 adolescents aged between 12 to 18. They were nationally recruited in Greece through an online survey that was hosted on the platform of Qualtrics. Analysis revealed excellent reliability with Cronbach’s alpha coefficients α = .939 for IGDS9-SF and α = .940 for IAT. The use of Pearson product-moment correlation revealed a significant positive relationship between IGDS9-SF and IAT r (241) =.45, p < .001. Due to inconsistencies in terminology and tests in the field of IGD, what is recommended for future research is a consensus regarding IGD testing and research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20gaming%20disorder" title="internet gaming disorder">internet gaming disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=IGDS9-SF" title=" IGDS9-SF"> IGDS9-SF</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometric%20properties" title=" psychometric properties"> psychometric properties</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20addiction" title=" internet addiction"> internet addiction</a> </p> <a href="https://publications.waset.org/abstracts/178724/translation-in-greek-and-psychometric-properties-of-the-9-item-internet-gaming-disorder-scale-short-form-igds9-sf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178724.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">56</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">3254</span> Modification of Underwood's Equation to Calculate Minimum Reflux Ratio for Column with One Side Stream Upper Than Feed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Mousavian">S.

There are different ways to design of distillation column. One of these ways is short cut method. In short cut method, material balance and equilibrium are employed to calculate number of tray in distillation column. There are different methods that are classified in short cut method. One of these methods is Fenske-Underwood-Gilliland method. In this method, minimum reflux ratio should be calculated by underwood equation. Underwood proposed an equation that is useful for simple distillation column with one feed and one top and bottom product. In this study, underwood method is developed to predict minimum reflux ratio for column with one side stream upper than feed. The result of this model compared with McCabe-Thiele method.

The anthropometric variables were measured as 8 skinfolds, 12 circumferences, 06 lengths and 05 breadths, stature, sitting height, arm span, body mass, hand grip strength and leg strength. The batsmen of under-19 and under-16 found similar in skinfolds, sum of skinfolds, circumferences and breadth measurements but significantly lesser than the senior team batsmen. Senior and Under-19 batsmen were almost found similar in segmental lengths, heights and arm span but significantly higher than the under-16 batsmen. Breadth measurements the under-19 found higher than the senior and u-16 batsmen. The hand grips strength of the senior batsmen significantly high than the uder-19 and under-16 players and both groups were similar and no significant difference were found in leg strength of all three groups batsmen. Leg strength were found significant correlation with wrist, hip, thigh, and calf girth and handgrip strength. The hand grip strength were found correlated with all variables except biceps, mid-thigh skinfold, segmental length, humerus breadth. It is concluded from the present study that the girth segments and hand grip strength are the predictors of good performance in cricket batting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cricket%20batting" title="cricket batting">cricket batting</a>, <a href="https://publications.waset.org/abstracts/search?q=batsmen" title=" batsmen"> batsmen</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title=" anthropometry"> anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20segments" title=" body segments"> body segments</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20grip%20strength" title=" hand grip strength"> hand grip strength</a> </p> <a href="https://publications.waset.org/abstracts/21707/an-assessment-of-the-anthropometric-characteristics-of-malaysian-cricket-batsmen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21707.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">575</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">3252</span> The Impact of Two Factors on EFL Learners' Fluency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Behfar">Alireza Behfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdavi"> Mohammad Mahdavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, in the light of progress in the world of science, technology and communications, mastery of learning international languages is a sure and needful matter. In learning any language as a second language, progress and achieving a desirable level in speaking is indeed important for approximately all learners. In this research, we find out how preparation can influence L2 learners' oral fluency with respect to individual differences in working memory capacity. The participants consisted of sixty-one advanced L2 learners including MA students of TEFL at Isfahan University as well as instructors teaching English at Sadr Institute in Isfahan. The data collection consisted of two phases: A working memory test (reading span test) and a picture description task, with a one-month interval between the two tasks. Speaking was elicited through speech generation task in which the individuals were asked to discuss four topics emerging in two pairs. The two pairs included one simple and one complex topic and was accompanied by planning time and without any planning time respectively. Each topic was accompanied by several relevant pictures. L2 fluency was assessed based on preparation. The data were then analyzed in terms of the number of syllables, the number of silent pauses, and the mean length of pauses produced per minute. The study offers implications for strategies to improve learners’ both fluency and working memory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two%20factors" title="two factors">two factors</a>, <a href="https://publications.waset.org/abstracts/search?q=fluency" title=" fluency"> fluency</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory%20capacity" title=" working memory capacity"> working memory capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=preparation" title=" preparation"> preparation</a>, <a href="https://publications.waset.org/abstracts/search?q=L2%20speech%20production%20reading%20span%20test%20picture%20description" title=" L2 speech production reading span test picture description"> L2 speech production reading span test picture description</a> </p> <a href="https://publications.waset.org/abstracts/50214/the-impact-of-two-factors-on-efl-learners-fluency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50214.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">230</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">3251</span> Blood Lipid Profile and Liver Lipid Peroxidation in Normal Rat Fed with Different Concentrations of Acacia senegal and Acacia seyal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eqbal%20M.%20A.%20Dauqan">Eqbal M.

It provides a scope for waste reduction and re-use of plastics in the construction industry on a large scale. Structural use of fibre reinforced concrete is limited to short span members and low reliability classes. In this study, recycled carpet fibres made of 95% polypropylene with length of 45mm were used for experimental investigations. The performance of recycled polypropylene fibres under structural loading has been compared with commercially available virgin fibres at low volume fractions of less than 1%. A series of 100 mm cubes and 125x200x2000 mm beams were used to conduct strength tests in bending and compression to measure the influence of type and volume of fibres on the structural behaviour of fibre reinforced concrete beams. The workability of the concrete mix decreased as a function of fibre content and resulted in a modification of the mix design. The beams failed in a pseudo-ductile manner with an enhanced bending capacity. The specimens showed significant improvement in the post-cracking behaviour and load carrying ability as compared to conventional reinforced concrete members. This was associated to the binding properties of the fibres in the concrete matrix. With the inclusion of fibres at low volumes of 0-0.5%, there was reduction in crack sizes and deflection. This study indicates that the inclusion of recycled polypropylene fibres at low volumes augments the structural behaviour of concrete as compared to conventional reinforced concrete as well as virgin fibre reinforced concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibre%20reinforced%20concrete" title="fibre reinforced concrete">fibre reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled" title=" recycled"> recycled</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/40423/structural-performance-evaluation-of-concrete-beams-reinforced-with-recycled-and-virgin-plastic-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40423.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">247</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">3249</span> Evaluation of Soil Thermal-Entropy Properties with a Single-Probe Heat-Pulse Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdull%20Halim%20Abdull">Abdull Halim Abdull</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasiman%20Sapari"> Nasiman Sapari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Haikal%20Asyraf%20Bin%20Anuar"> Mohammad Haikal Asyraf Bin Anuar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although soil thermal properties are required in many areas to improve oil recovery, they are seldom measured on a routine basis. Reasons for this are unclear, but may be related to a lack of suitable instrumentation and entropy theory. We integrate single probe thermal gradient for the radial conduction of a short-duration heat pulse away from a single electrode source, and compared it with the theory for an instantaneously heated line source. By measuring the temperature response at a short distance from the line source, and applying short-duration heat-pulse theory, we can extract all the entropy properties, the thermal diffusivity, heat capacity, and conductivity, from a single heat-pulse measurement. Results of initial experiments carried out on air-dry sand and clay materials indicate that this heat-pulse method yields soil thermal properties that compare well with thermal properties measured by single electrode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entropy" title="entropy">entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20probe%20thermal%20gradient" title=" single probe thermal gradient"> single probe thermal gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20thermal" title=" soil thermal"> soil thermal</a>, <a href="https://publications.waset.org/abstracts/search?q=probe%20heat" title=" probe heat "> probe heat </a> </p> <a href="https://publications.waset.org/abstracts/5201/evaluation-of-soil-thermal-entropy-properties-with-a-single-probe-heat-pulse-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5201.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">446</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">3248</span> An Integrated Approach to Find the Effect of Strain Rate on Ultimate Tensile Strength of Randomly Oriented Short Glass Fiber Composite in Combination with Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharad%20Shrivastava">Sharad Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Arun%20Jalan"> Arun Jalan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study tensile testing was performed on randomly oriented short glass fiber/epoxy resin composite specimens which were prepared using hand lay-up method. Samples were tested over a wide range of strain rate/loading rate from 2mm/min to 40mm/min to see the effect on ultimate tensile strength of the composite. A multi layered 'back propagation artificial neural network of supervised learning type' was used to analyze and predict the tensile properties with strain rate and temperature as given input and output as UTS to predict. Various network structures were designed and investigated with varying parameters and network sizes, and an optimized network structure was proposed to predict the UTS of short glass fiber/epoxy resin composite specimens with reasonably good accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20fiber%20composite" title="glass fiber composite">glass fiber composite</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20rate" title=" strain rate"> strain rate</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a> </p> <a href="https://publications.waset.org/abstracts/18900/an-integrated-approach-to-find-the-effect-of-strain-rate-on-ultimate-tensile-strength-of-randomly-oriented-short-glass-fiber-composite-in-combination-with-artificial-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18900.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">437</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">3247</span> Analysis of Rectangular Concrete-Filled Double Skin Tubular Short Columns with External Stainless Steel Tubes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omnia%20F.%20Kharoob">Omnia F.

Alternatively, lean duplex stainless steel has recently gained significant interest for its high structural performance, similar corrosion resistance and lower cost compared to the austenitic steel grade. Hence, this paper presents the nonlinear finite element (FE) analysis, behaviour and design of rectangular outer lean duplex stainless steel (EN 1.4162) CFDST short columns under compression. All classes of the outer rectangular hollow section according to the depth-to-thickness (D/t) ratios were considered. The results showed that the axial ultimate strength of rectangular CFDST short columns increased linearly by increasing the concrete compressive strength, while it does not influence when changing the hollow ratios. Finally, the axial capacities were compared with the available design methods, and recommendations were conducted for the design strength of this type of column. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete-filled%20double%20skin%20columns" title="concrete-filled double skin columns">concrete-filled double skin columns</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20duplex%20stainless%20steel" title=" lean duplex stainless steel"> lean duplex stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=ultimate%20axial%20strength" title=" ultimate axial strength"> ultimate axial strength</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20columns" title=" short columns"> short columns</a> </p> <a href="https://publications.waset.org/abstracts/78794/analysis-of-rectangular-concrete-filled-double-skin-tubular-short-columns-with-external-stainless-steel-tubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78794.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">302</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">3246</span> Investigating the Impact of Super Bowl Participation on Local Economy: A Perspective of Stock Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rui%20Du">Rui Du</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper attempts to assess the impact of a major sporting event —the Super Bowl on the local economies. The identification strategy is to compare the winning and losing cities at the National Football League (NFL) conference finals under the assumption of similar pre-treatment trends. The stock market performances of companies headquartered in these cities are used to capture the sudden changes in local economic activities during a short time span. The exogenous variations in the football game outcome allow a straightforward difference-in-differences approach to identify the effect. This study finds that the post-event trends in winning and losing cities diverge despite the fact that both cities have economically and statistically similar pre-event trends. Empirical analysis provides suggestive evidence of a positive, significant local economic impact of conference final wins, possibly through city image enhancement. Further empirical evidence shows the presence of heterogeneous effects across industrial sectors, suggesting that city image enhancing the effect of the Super Bowl participation is empirically relevant for the changes in the composition of local industries. Also, this study also adopts a similar strategy to examine the local economic impact of Super Bowl successes, however, finds no statistically significant effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Super%20Bowl%20Participation" title="Super Bowl Participation">Super Bowl Participation</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20economies" title=" local economies"> local economies</a>, <a href="https://publications.waset.org/abstracts/search?q=city%20image%20enhancement" title=" city image enhancement"> city image enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=difference-in-di%0Bfferences" title=" difference-in-differences"> difference-in-differences</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20sectors" title=" industrial sectors"> industrial sectors</a> </p> <a href="https://publications.waset.org/abstracts/44496/investigating-the-impact-of-super-bowl-participation-on-local-economy-a-perspective-of-stock-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44496.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">240</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">3245</span> Experimental Partial Discharge Localization for Internal Short Circuits of Transformers Windings </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jalal%20M.%20Abdallah">Jalal M.

The measurements are based on the transfer function methods in transformer windings by frequency response analysis (FRA). Numbers of tests conditions were applied to obtain the sensitivity frequency responses of a transformer for different type of faults simulated in a particular phase. The frequency responses were analyzed for the sensitivity of different test conditions to detect and identify the starting of small faults, which are sources of PD. In more detail, the aim is to explain applicability and sensitivity of advanced PD measurements for small short circuits and its localization. The experimental results presented in the paper will help in understanding the sensitivity of FRA measurements in detecting various types of internal winding short circuits in the transformer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20response%20analysis%20%28FRA%29" title="frequency response analysis (FRA)">frequency response analysis (FRA)</a>, <a href="https://publications.waset.org/abstracts/search?q=measurements" title=" measurements"> measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20function" title=" transfer function"> transfer function</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a> </p> <a href="https://publications.waset.org/abstracts/7119/experimental-partial-discharge-localization-for-internal-short-circuits-of-transformers-windings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7119.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">281</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">3244</span> CSR Reporting, State Ownership, and Corporate Performance in China: Proof from Longitudinal Data of Publicly Traded Enterprises from 2006 to 2020</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wanda%20Luen-Wun%20Siu">Wanda Luen-Wun Siu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaowen%20Zhang"> Xiaowen Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper offered the primary methodical proof on how CSR reporting related to enterprise earnings in listed firms in China in light of most evidence focusing on cross-sectional data or data in a short span of time. Using full economic and business panel data on China’s publicly listed enterprise from 2006 to 2020 over two decades in the China Stock Market and Accounting Research database, we found initial evidence of significant direct relations between CSR reporting and firm corporate performance in both state-owned and privately owned firms over this period, supporting the stakeholder theory. Results also revealed that state-owned enterprises performed as well as private enterprises in the current period. But private enterprises performed better than state-owned enterprises in the subsequent years. Moreover, the release of social responsibility reports had a more significant impact on the financial performance of state-owned and private enterprises in the current period than in the subsequent periods. Specifically, CSR release was not significantly associated with the financial performance of state-owned enterprises on the lag of the first, second, and third periods. But it had an impact on the lag of the first, second, and third periods among private enterprises. Such findings suggested that CSR reporting helped improve the corporate financial performance of state-owned and private enterprises in the current period, but this kind of effect was more significant among private enterprises in the lag periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China%E2%80%99s%20listed%20firms"
