signals in the long-baseline RTK positioning, a long-baseline RTK positioning method based on the BDS-3 penta-frequency ionospheric-reduced (IR) combinations is proposed. First, the low noise and weak ionospheric delay characteristics of the multi-frequency combined observations of BDS-3is analyzed. Second, the multi-frequency extra-wide-lane (EWL)/ wide-lane (WL) combinations with long-wavelengths are constructed. Third, the fixed IR EWL combinations are used to constrain the IR WL, then constrain narrow-lane (NL)ambiguityies and start multi-epoch filtering. There is no need to consider the influence of ionospheric parameters in the third step. Compared with the estimated ionospheric model, the proposed method reduces the number of parameters by half, so it is suitable for the use of multi-frequency and multi-system real-time RTK. The results using real data show that the stepwise fixed model of the IR EWL/WL/NL combinations can realize long-baseline instantaneous cimeter-level positioning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=penta-frequency" title="penta-frequency">penta-frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=ionospheric-reduced%20%28IR%29" title=" ionospheric-reduced (IR)"> ionospheric-reduced (IR)</a>, <a href="https://publications.waset.org/abstracts/search?q=RTK%20positioning" title=" RTK positioning"> RTK positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=long-baseline" title=" long-baseline"> long-baseline</a> </p> <a href="https://publications.waset.org/abstracts/145983/long-baseline-single-epoch-rtk-positioning-method-based-on-bds-3-and-galileo-penta-frequency-ionosphere-reduced-combinations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145983.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">28004</span> Estimating the Ladder Angle and the Camera Position From a 2D Photograph Based on Applications of Projective Geometry and Matrix Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inigo%20Beckett">Inigo Beckett</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In forensic investigations, it is often the case that the most potentially useful recorded evidence derives from coincidental imagery, recorded immediately before or during an incident, and that during the incident (e.g. a ‘failure’ or fire event), the evidence is changed or destroyed. To an image analysis expert involved in photogrammetric analysis for Civil or Criminal Proceedings, traditional computer vision methods involving calibrated cameras is often not appropriate because image metadata cannot be relied upon. This paper presents an approach for resolving this problem, considering in particular and by way of a case study, the angle of a simple ladder shown in a photograph. The UK Health and Safety Executive (HSE) guidance document published in 2014 (INDG455) advises that a leaning ladder should be erected at 75 degrees to the horizontal axis. Personal injury cases can arise in the construction industry because a ladder is too steep or too shallow. Ad-hoc photographs of such ladders in their incident position provide a basis for analysis of their angle. This paper presents a direct approach for ascertaining the position of the camera and the angle of the ladder simultaneously from the photograph(s) by way of a workflow that encompasses a novel application of projective geometry and matrix analysis. Mathematical analysis shows that for a given pixel ratio of directly measured collinear points (i.e. features that lie on the same line segment) from the 2D digital photograph with respect to a given viewing point, we can constrain the 3D camera position to a surface of a sphere in the scene. Depending on what we know about the ladder, we can enforce another independent constraint on the possible camera positions which enables us to constrain the possible positions even further. Experiments were conducted using synthetic and real-world data. The synthetic data modeled a vertical plane with a ladder on a horizontally flat plane resting against a vertical wall. The real-world data was captured using an Apple iPhone 13 Pro and 3D laser scan survey data whereby a ladder was placed in a known location and angle to the vertical axis. For each case, we calculated camera positions and the ladder angles using this method and cross-compared them against their respective ‘true’ values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20analysis" title="image analysis">image analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=projective%20geometry" title=" projective geometry"> projective geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=homography" title=" homography"> homography</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title=" photogrammetry"> photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=ladders" title=" ladders"> ladders</a>, <a href="https://publications.waset.org/abstracts/search?q=Forensics" title=" Forensics"> Forensics</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathematical%20modeling" title=" Mathematical modeling"> Mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=planar%20geometry" title=" planar geometry"> planar geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20analysis" title=" matrix analysis"> matrix analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=collinear" title=" collinear"> collinear</a>, <a href="https://publications.waset.org/abstracts/search?q=cameras" title=" cameras"> cameras</a>, <a href="https://publications.waset.org/abstracts/search?q=photographs" title=" photographs"> photographs</a> </p> <a href="https://publications.waset.org/abstracts/181525/estimating-the-ladder-angle-and-the-camera-position-from-a-2d-photograph-based-on-applications-of-projective-geometry-and-matrix-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181525.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">53</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">28003</span> Design and Stability Analysis of Fixed Wing – VTOL UAV</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Eldenali">Omar Eldenali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Bufares"> Ahmed M.

This means that the UAV is capable of not only taking off, landing, or hovering like a multirotor aircraft but also cruising like a fixed wing UAV. In this study, the conceptual design of 15 kg takeoff weight twin-tail boom configuration FW-VTOL plane is carried out, the initial sizing of the plane is conducted, and both the horizontal and vertical tail configurations are estimated. Moreover, the power required for each stage of flight is determined. Finally, the stability analysis of the plane based on this design is performed, the results shows that this design based on the suggested flight mission is stable and can be utilized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FW-VTOL" title="FW-VTOL">FW-VTOL</a>, <a href="https://publications.waset.org/abstracts/search?q=initial%20sizing" title=" initial sizing"> initial sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=constrain%20analysis" title=" constrain analysis"> constrain analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a> </p> <a href="https://publications.waset.org/abstracts/173709/design-and-stability-analysis-of-fixed-wing-vtol-uav" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173709.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">88</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">28002</span> Being Funny is a Serious Business for Feminine Brands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Murtuza%20Soofi">Mohammed Murtuza Soofi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Marketers and Researchers alike have simultaneously, yet in mutually exclusive instances, promote the use of humour by brands in their communication and gendering of brands, as both enhance brand equity and can generate positive attitudinal responses from customers. However, the gendering of brands comes with associated gendered stereotypical expectations. The current paper consolidates the long standing literature on gender role/stereotype theory and brand gender theories establishing a theoretical framework for understanding how gender-based stereotypes about humour can influence consumers’ attitudinal responses towards brands. Design/methodology/approach: Using parallel constrain satisfaction theory as domain theory to explain the highhandedness of stereotypes and gender stereotype theories (particularly around feminine use of humour), we explain why gender based stereotypes could constrain brand behaviors, and in turn, feminine brands get penalised for using witty, aggressive and self-enhancing humor. Findings: Extension of gender stereotypes to anthropomorphised brands will lead consumers to judge the use of negative humour by a feminine brand as less appropriate, which will trigger the causal chain of reduced sense of communal appropriateness and brand warmth which will result in a negative attitude towards the brand. Originality/value: Brand gendering being susceptible to gender based stereotypes, has very little attention in the literature and hence use of negative humour (stereotypical male behaviour), has never been studied in the context of gendered brands. It also helps understand to what extent stereotypes will impact attitudinal responses to the brand. Our work can help understand when heavily gendered brands can optimise the use of humour and when they can avoid it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brand%20femininity" title="brand femininity">brand femininity</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20gender" title=" brand gender"> brand gender</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20stereotypes" title=" gender stereotypes"> gender stereotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=humour" title=" humour"> humour</a> </p> <a href="https://publications.waset.org/abstracts/141797/being-funny-is-a-serious-business-for-feminine-brands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141797.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">203</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">28001</span> E-Bike FE Model Analysis: Connection Stiffness of Elements with Different DOFs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lele%20Zhang">Lele Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Leng%20Choo"> Hui Leng Choo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Konyukhov"> Alexander Konyukhov</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuguang%20Li"> Shuguang Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finite Element (FE) model of simplified e-bike structure was generated by main frame with two tiers, which consisted of pipe, mass, beam, and shell elements (pipe 289, beam188, shell 181, shell 281, combin14, link11, mass21).

In Low and Middle Income Countries (LMIC), resource constrain appears to be a major challenge in implementing the conventional QA system. We designed and implemented a modified LQAS model for QA of malaria parasite (MP) microscopy and RDT in a State Specialist Hospital (SSH) and a University Health Clinic (UHC) in Kano, Nigeria. The capacities of both facilities for MP microscopy and RDT were assessed before implementing a modified LQAS over a period of 3 months. Quality indicators comprising the qualities of blood film and staining, MP positivity rates, concordance rates, error rates (in terms of false positives and false negatives), sensitivity and specificity were monitored and evaluated. Seventy one percent (71%) of the basic requirements for malaria microscopy was available in both facilities, with the absence of certifies microscopists, SOPs and Quality Assurance mechanisms. A daily average of 16 to 32 blood samples were tested with a blood film staining quality of >70% recorded in both facilities. Using microscopy, the MP positivity rates were 50.46% and 19.44% in SSH and UHS respectively, while the MP positivity rates were 45.83% and 22.78% in SSH and UHS when RDT was used. Higher concordance rates of 88.90% and 93.98% were recorded in SSH and UHC respectively using microscopy, while lower rates of 74.07% and 80.58% in SSH and UHC were recorded when RDT was used. In both facilities, error rates were higher when RDT was used than with microscopy. Sensitivity and specificity were higher when microscopy was used (95% and 84% in SSH; 94% in UHC) than when RDT was used (72% and 76% in SSH; 78% and 81% in UHC). It could be feasible to implement an integrated QA model for MP microscopy and RDT using modified LQAS in Malaria Control Programmes in Low and Middle Income Countries that might have resource constrain for parasite-base diagnosis of malaria to justify ACT treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malaria" title="malaria">malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopy" title=" microscopy"> microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20assurance" title=" quality assurance"> quality assurance</a>, <a href="https://publications.waset.org/abstracts/search?q=RDT" title=" RDT"> RDT</a> </p> <a href="https://publications.waset.org/abstracts/44111/modified-lot-quality-assurance-sampling-lqas-model-for-quality-assessment-of-malaria-parasite-microscopy-and-rapid-diagnostic-tests-in-kano-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44111.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">226</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">27999</span> The Impact of Corporate Governance Mechanisms on Earnings Management Practices: Evidence from Jordan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lara%20Al-Haddad">Lara Al-Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Whittington"> Mark Whittington</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to examine the impact of two influential internal corporate governance mechanisms, namely board characteristics and ownership structure on the use of real activities-based and accrual-based earnings management by Jordanian public firms. Using panel data from Jordanian public firms after the introduction of the Jordanian Corporate Governance Code (JCGC) in 2009, the study finds both institutional ownership and managerial ownership constrain the use of real and accrual earnings manipulations. On the other side, both independent directors and largest shareholders are found to exaggerate the incidence of using real and accrual earnings management. The study also examines the trade-off between real and accrual earnings management and found that Jordanian firms use a combination of real and accrual-based earnings management to obtain the greatest effect on earnings reporting strategies. For the purpose of this study, three types of real earnings management are considered: sales manipulation, overproduction, and the abnormal reduction of discretionary expenditures. The abnormal discretionary accrual is considered for accruals management. While for the internal corporate governance mechanisms; board characteristics are examined by using board independence, board size, and CEO-duality; and ownership structure is examined by using managerial ownership, institutional ownership, foreign ownership and largest shareholder ownership. To the best knowledge of the researchers, this study is the first to examine the relationship between board characteristics and real earnings management in Jordan. Further, it is the first to examine the relationship between corporate governance mechanisms and discretionary accruals after the introduction of the Jordanian Corporate Governance Code in 2009. Thus, the findings of this study have important policy implications for policymakers, regulators, standard setters, audit professional, and investors in their attempts to constrain the practice of earnings management, whether real or accrual, and to improve the financial reporting quality in Jordan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=board%20characteristics" title="board characteristics">board characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan" title=" Jordan"> Jordan</a>, <a href="https://publications.waset.org/abstracts/search?q=ownership%20structure" title=" ownership structure"> ownership structure</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20earnings%20management" title=" real earnings management"> real earnings management</a> </p> <a href="https://publications.waset.org/abstracts/63986/the-impact-of-corporate-governance-mechanisms-on-earnings-management-practices-evidence-from-jordan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63986.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">347</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">27998</span> Novel Formal Verification Based Coverage Augmentation Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Surinder%20Sood">Surinder Sood</a>, <a href="https://publications.waset.org/abstracts/search?q=Debajyoti%20Mukherjee"> Debajyoti Mukherjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Formal verification techniques have become widely popular in pre-silicon verification as an alternate to constrain random simulation based techniques. This paper proposed a novel formal verification-based coverage augmentation technique in verifying complex RTL functional verification faster. The proposed approach relies on augmenting coverage analysis coming from simulation and formal verification. Besides this, the functional qualification framework not only helps in improving the coverage at a faster pace but also aids in maturing and qualifying the formal verification infrastructure.

Two geophysical techniques were employed: multichannel analysis of surface waves (MASW) and electric resistivity tomography (ERT).The MASW data was acquired at each test location using different array lengths and different array orientations (to increase the probability of getting interpretable data in karst terrain). The ERT data were acquired using a dipole-dipole array consisting of 168 electrodes. The MASW data was interpreted (re: estimated depth to physical top of rock) and used to constrain and verify the interpretation of the ERT data. The ERT data indicates poorer quality MASW data were acquired in areas where there was significant local variation in the depth to top of rock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dipole-dipole" title="dipole-dipole">dipole-dipole</a>, <a href="https://publications.waset.org/abstracts/search?q=ERT" title=" ERT"> ERT</a>, <a href="https://publications.waset.org/abstracts/search?q=Karst%20terrains" title=" Karst terrains"> Karst terrains</a>, <a href="https://publications.waset.org/abstracts/search?q=MASW" title=" MASW "> MASW </a> </p> <a href="https://publications.waset.org/abstracts/58233/rodriguez-diego-del-valle-martin-hargreaves-matias-riveros-jose-luis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58233.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">315</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">27996</span> Two-Stage Hospital Efficiency Analysis Including Qualitative Evidence: A Greek Case</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panos%20Xenos">Panos Xenos</a>, <a href="https://publications.waset.org/abstracts/search?q=Milton%20Nektarios"> Milton Nektarios</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Yfantopoulos"> John Yfantopoulos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Policy makers, professional organizations and payers have introduced a variety of initiatives and reforms for the health systems worldwide, aimed at improving hospital efficiency. Their efforts are concentrated in two main categories: to constrain increasing healthcare costs and to enhance quality of services provided. Research Objectives: This study examines the efficiency of 112 Greek public hospitals for the year 2009, evaluates the importance of bootstrapping techniques and investigates the effect of contextual factors on hospital efficiency. Furthermore, the effect of qualitative evidence, on hospital efficiency is explored using data from 28 large hospitals. Methods: We applied Data Envelopment Analysis, augmented by bootstrapping techniques, to estimate efficiency scores. In order to measure the effect of environmental factors on hospital efficiency we used Tobit regression analysis. The significance of our models is evaluated using statistical tests to compare distributions. Results: The Kolmogorov-Smirnov test between the original and the bootstrap-corrected efficiency indicates that their distributions are significantly different (p-value<0.01). The environmental factors, that seem to influence efficiency, are Occupancy Rating and the ratio between Outpatient Visits and Inpatient Days. Results indicate that the inclusion of the quality variable in DEA modelling generates statistically significant variations in efficiency scores (p-value<0.05). Conclusions: The inclusion of quality variables and the use of bootstrap resampling in efficiency analysis impose a statistically significant effect on the distribution of efficiency scores. As a policy conclusion we highlight the importance of these methods on hospital efficiency analysis and, by implication, on healthcare resource allocation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hospitals" title="hospitals">hospitals</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20envelopment%20analysis" title=" data envelopment analysis"> data envelopment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Greek%20public%20hospital%20sector" title=" Greek public hospital sector"> Greek public hospital sector</a> </p> <a href="https://publications.waset.org/abstracts/41560/two-stage-hospital-efficiency-analysis-including-qualitative-evidence-a-greek-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41560.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">310</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">27995</span> Earth Tremors in Nigeria: A Precursor to Major Disaster?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluseyi%20Adunola%20Bamisaiye">Oluseyi Adunola Bamisaiye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The frequency of occurrence of earth tremor in Nigeria has increased tremendously in recent years. Slow earthquakes/ tremor have preceded some large earthquakes in some other regions of the world and the Nigerian case may not be an exception. Timely and careful investigation of these tremors may reveal their relation to large earthquakes and provides important clues to constrain the slip rates on tectonic faults. Thus making it imperative to keep under watch and also study carefully the tectonically active terrains within the country, in order to adequately forecast, prescribe mitigation measures and in order to avoid a major disaster. This report provides new evidence of a slow slip transient in a strongly locked seismogenic zone of the Okemesi fold belt. The aim of this research is to investigate the different methods of earth tremor monitoring using fault slip analysis and mapping of Okemesi hills, which has been the most recent epicenter to most of the recent tremors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earth%20tremor" title="earth tremor">earth tremor</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20slip" title=" fault slip"> fault slip</a>, <a href="https://publications.waset.org/abstracts/search?q=intraplate%20activities" title=" intraplate activities"> intraplate activities</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20tectonics" title=" plate tectonics "> plate tectonics </a> </p> <a href="https://publications.waset.org/abstracts/124110/earth-tremors-in-nigeria-a-precursor-to-major-disaster" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124110.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">156</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">27994</span> Performance Analysis of N-Tier Grid Protocol for Resource Constrained Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jai%20Prakash%20Prasad">Jai Prakash Prasad</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Chandra%20Mohan"> Suresh Chandra Mohan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern wireless sensor networks (WSN) consist of small size, low cost devices which are networked through tight wireless communications.

However, it is unclear whether the elements of effective professional learning result in transformed teacher practice in the classroom. This research project is interested in 4C teacher professional learning. The professional learning practices to assist teachers in transforming their practice to integrate the 4C capabilities seldom feature in the academic literature. The 4Cs are a shorthand way of representing the concepts of communication, collaboration, creativity, and critical reflection and refer to the capabilities needed for deeper learning, personal growth, and effective participation in society. The New South Wales curriculum review (2020) acknowledges that identifying, teaching, and assessing the 4C capabilities are areas of challenge for teachers. However, it also recognises that it is essential for teachers to build the confidence and capacity to understand, teach and assess the capabilities necessary for learners to thrive in the 21st century. This qualitative research project explores the professional learning experiences of sixteen teachers in four different primaries (K-6) settings in Sydney, Australia, who are learning to integrate, teach and assess the 4Cs. The project draws on the Theory of Practice Architecture as a framework to analyse and interpret teachers' experiences in each site. The sixteen participants in the study are teachers from four primary settings and include early career, experienced, and teachers in leadership roles (including the principal). In addition, some of the participants are also teachers who are learning within a Community of Practice (CoP) as their school setting is engaged in a 4C professional learning, Community of Practice. Qualitative and arts-informed research methods are utilised to examine the cultural-discursive, social-political, and material-economic practice arrangements of the site, explore how these arrangements may have shaped the professional learning experiences of teachers, and in turn, influence the teaching practices of the 4Cs in the setting. The research is in the data analysis stage (October 2022), with preliminary findings pending. The research objective is to investigate the elements of the professional learning experiences undertaken by teachers to teach the 4Cs in the primary setting. The lens of practice architectures theory is used to identify the influence of the practice architectures on critical praxis in each site and examine how the practice arrangements enable or constrain the teaching of 4C capabilities. This research aims to offer deep insight into the practice arrangements which may enable or constrain teacher professional learning in the 4Cs. Such insight from this study may contribute to a better understanding of the practices that enable teachers to transform their practice to achieve the integration, teaching, and assessment of the 4C capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=4Cs" title="4Cs">4Cs</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=creativity" title=" creativity"> creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20reflection" title=" critical reflection"> critical reflection</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20professional%20learning" title=" teacher professional learning"> teacher professional learning</a> </p> <a href="https://publications.waset.org/abstracts/158108/learning-to-transform-transforming-to-learn-an-exploration-of-teacher-professional-learning-in-the-4cs-communication-collaboration-creativity-and-critical-reflection-in-the-primary-k-6-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27992</span> A Survey of Grammar-Based Genetic Programming and Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20T.%20Wilson">Matthew T.

Tavuyanago</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cartels within the international competition law framework have been dubbed the most egregious of competition law violations; this is because they entail a concerted effort by two or more competitor firms to knowingly ‘rob’ consumers of their welfare through their cooperation instead of competition. The net effect of cartel conduct is that the market is distorted as the colluding firms gain enough market power to constrain the supply of goods or services, ultimately driving up prices. As a result, consumers end up paying inflated prices for goods and services, which eventually affects their welfare. It is against this backdrop that competition authorities worldwide have mounted a robust fight against the proliferation of cartels. In South Africa, the fight against cartels saw an amendment to the Competition Act to allow for criminal prosecution of individuals who cause their firms to take part in cartels. The Competition Amendment Act 1 of 2009 introduced section 73A into the principal Competition Act, making it a criminal offence to engage in cartel conduct. This paper assesses the rationale for criminalisation of cartel conduct, discusses the challenges or potential challenges associated with criminalisation, and provides an evaluation of the efficacy of criminalisation of cartel conduct. It questions whether criminal sanctions for cartel conduct as a competition enforcement tool aimed at deterring such conduct are generally effective and whether they have been effective in South Africa specifically. It concludes by offering recommendations on how to effectively root out cartels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cartels" title="cartels">cartels</a>, <a href="https://publications.waset.org/abstracts/search?q=criminalisation" title=" criminalisation"> criminalisation</a>, <a href="https://publications.waset.org/abstracts/search?q=competition" title=" competition"> competition</a>, <a href="https://publications.waset.org/abstracts/search?q=deterrence" title=" deterrence"> deterrence</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/156959/an-analysis-of-the-efficacy-of-criminal-sanctions-in-combating-cartel-conduct-the-case-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156959.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">100</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">27989</span> Examining the Market Challenges That Constrain the Proper Sales of Farming Produces Amongst the Small-Scale Farms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simiso%20Fisokuhle%20Nyandeni">Simiso Fisokuhle Nyandeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change has turned out to be a pandemic that has drawn the attention of many countries’ households around the globe, especially those whose livelihood and economic status depend on agricultural productivity. Hence, the agricultural sector is regarded as the sector that is most dependent on climate conditions for its productivity/harvest, yet in recent years this sector has been experiencing drought. However, adaptation seems to be a tool that every farmer looks upon as a solution to their challenges as their productivity keeps on being vulnerable to climate effects. Thus, exposure/access to the market seems to be a major challenge that faces especially small-scale farmers. We, therefore, examine the small-scale farmers’ constraints or challenges towards getting access to the market for them to get proper sales of their farming products. As a result, the adaptation capacity of every farm household varies on the financial status. <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=small-scale%20farming" title=" small-scale farming"> small-scale farming</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture%20sector" title=" agriculture sector"> agriculture sector</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation" title=" adaptation"> adaptation</a> </p> <a href="https://publications.waset.org/abstracts/149581/examining-the-market-challenges-that-constrain-the-proper-sales-of-farming-produces-amongst-the-small-scale-farms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149581.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">86</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">27988</span> Static Response of Homogeneous Clay Stratum to Imposed Structural Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aaron%20Aboshio">Aaron Aboshio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical study of the static response of homogeneous clay stratum considering a wide range of cohesion and subject to foundation loads is presented.

This intriguing correlation is consistent with data collected by the Telescope Array, which have revealed a much more pronounced directional 'hot spot' in arrival directions not far from the starburst galaxy M82. In this work, we assume starbursts are sources of UHECRs, and we investigate the prospects to use the observed distribution of UHECR arrival directions to constrain galactic magnetic field models. We show that if the Telescope Array hot spot indeed originates on M82, UHECR data would place a strong constraint on the turbulent component of the galactic magnetic field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=galactic%20magnetic%20field" title="galactic magnetic field">galactic magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Auger%20observatory" title=" Pierre Auger observatory"> Pierre Auger observatory</a>, <a href="https://publications.waset.org/abstracts/search?q=telescope%20array" title=" telescope array"> telescope array</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-high%20energy%20cosmic%20rays" title=" ultra-high energy cosmic rays"> ultra-high energy cosmic rays</a> </p> <a href="https://publications.waset.org/abstracts/102702/the-galactic-magnetic-field-in-the-light-of-starburst-generated-ultrahigh-energy-cosmic-rays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102702.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27986</span> Bubbling in Gas Solids Fluidization at a Strouhal Number Tuned for Low Energy Dissipation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chenxi%20Zhang">Chenxi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weizhong%20Qian"> Weizhong Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=Fei%20Wei"> Fei Wei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gas solids multiphase flow is common in many engineering and environmental applications. Turbulence and multiphase flows are two of the most challenging topics in fluid mechanics, and when combined they pose a formidable challenge, even in the dilute dispersed regime. Dimensionless numbers are important in mechanics because their constancy can imply dynamic similarity between systems, despite possible differences in medium or scale. In the fluid mechanics literature, the Strouhal number is usually associated with the dimensionless shedding frequency of a von Karman wake; here we introduce this dimensionless number to investigate bubbling in gas solids fluidization. St=fA/U, which divides stroke frequency (f) and amplitude (A) by forward speed (U). The bubble behavior in a large two-dimensional bubbling fluidized bed (500mm×30mm×6000mm) is investigated. Our result indicates that propulsive efficiency is high and energy dissipation is low over a narrow range of St and usually within the interval 0.2<St<0.4. Due to least-action principle, we expect it to constrain the range of St that bubbles use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bubbles" title="bubbles">bubbles</a>, <a href="https://publications.waset.org/abstracts/search?q=Strouhal%20number" title=" Strouhal number"> Strouhal number</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20dissipation" title=" energy dissipation"> energy dissipation</a> </p> <a href="https://publications.waset.org/abstracts/45222/bubbling-in-gas-solids-fluidization-at-a-strouhal-number-tuned-for-low-energy-dissipation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45222.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">248</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">27985</span> Musculoskeletal Disorders among Employees of an Assembly Industrial Workshop: Biomechanical Constrain’s Semi-Quantitative Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Bouzgarrou">Lamia Bouzgarrou</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Omrane"> Amira Omrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Haithem%20Kalel"> Haithem Kalel</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Kammoun"> Salma Kammoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: During recent decades, mechanical and electrical industrial sector has greatly expanded with a significant employability potential. However, this sector faces the increasing prevalence of musculoskeletal disorders with heavy consequences associated with direct and indirect costs. Objective: The current intervention was motivated by large musculoskeletal upper limbs and back disorders frequency among the operators of an assembly workshop in a leader company specialized in sanitary equipment and water and gas connections. We aimed to identify biomechanical constraints among these operators through activity and biomechanical exposures semi-quantitative analysis based on video recordings and MUSKA-TMS software. Methods: We conducted, open observations and exploratory interviews at first, in order to overall understand work situation. Then, we analyzed operator’s activity through systematic observations and interviews. Finally, we conducted a semi-quantitative biomechanical constraints analysis with MUSKA-TMS software after representative activity period video recording. The assessment of biomechanical constrains was based on different criteria; biomechanical characteristics (work positions), aggravating factor (cold, vibration, stress, etc.) and exposure time (duration and frequency of solicitations, recovery phase); with a synthetic score of risk level variable from 1 to 4 (1: low risk of developing MSD and 4: high risk). Results: Semi-quantitative analysis objective many elementary operations with higher biomechanical constrains like high repetitiveness, insufficient recovery time and constraining angulation of shoulders, wrists and cervical spine. Among these risky elementary operations we sited the assembly of sleeve with the body, the assembly of axis, and the control on testing table of gas valves. Transformation of work situations were recommended, covering both the redevelopment of industrial areas and the integration of new tools and equipment of mechanical handling that reduces operator exposure to vibration. Conclusion: Musculoskeletal disorders are complex and costly disorders. Moreover, an approach centered on the observation of the work can promote the interdisciplinary dialogue and exchange between actors with the objective to maximize the performance of a company and improve the quality of life of operators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=musculoskeletal%20disorders" title="musculoskeletal disorders">musculoskeletal disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanical%20constrains" title=" biomechanical constrains"> biomechanical constrains</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-quantitative%20analysis" title=" semi-quantitative analysis"> semi-quantitative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a> </p> <a href="https://publications.waset.org/abstracts/102363/musculoskeletal-disorders-among-employees-of-an-assembly-industrial-workshop-biomechanical-constrains-semi-quantitative-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102363.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">27984</span> Mobile Augmented Reality for Collaboration in Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chong-Yang%20Qiao">Chong-Yang Qiao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mobile augmented reality (MAR) tracking targets from the surroundings and aids operators for interactive data and procedures visualization, potential equipment and system understandably. Operators remotely communicate and coordinate with each other for the continuous tasks, information and data exchange between control room and work-site. In the routine work, distributed control system (DCS) monitoring and work-site manipulation require operators interact in real-time manners. The critical question is the improvement of user experience in cooperative works through applying Augmented Reality in the traditional industrial field. The purpose of this exploratory study is to find the cognitive model for the multiple task performance by MAR. In particular, the focus will be on the comparison between different tasks and environment factors which influence information processing. Three experiments use interface and interaction design, the content of start-up, maintenance and stop embedded in the mobile application. With the evaluation criteria of time demands and human errors, and analysis of the mental process and the behavior action during the multiple tasks, heuristic evaluation was used to find the operators performance with different situation factors, and record the information processing in recognition, interpretation, judgment and reasoning. The research will find the functional properties of MAR and constrain the development of the cognitive model.

Gizmos was developed to supplement the existing curriculum by integrating it into the instructional programs. The program has some features using an inquiry-based simulation, in which students conduct exploration by using a worksheet while teachers use the teacher guidelines to direct and assess students’ performance In this study, the discussion about Gizmos highlights its features as the assessment media of mathematics learning for secondary school students. The discussion is based on the case study and literature review from the Indonesian context. The purpose of applying Gizmos as an assessment media refers to the diagnostic assessment. As a part of the diagnostic assessment, the teachers review the student exploration sheet, analyze particularly in the students’ difficulties and consider findings in planning future learning process. This assessment becomes important since the teacher needs the data about students’ persistent weaknesses. Additionally, this program also helps to build student’ understanding by its interactive simulation. Currently, the assessment over-emphasizes the students’ answers in the worksheet based on the provided answer keys while students perform their skill in translating the question, doing the simulation and answering the question. Whereas, the assessment should involve the multiple perspectives and sources of students’ performance since teacher should adjust the instructional programs with the complexity of students’ learning needs and styles. Consequently, the approach to improving the assessment components is selected to challenge the current assessment. The purpose of this challenge is to involve not only the cognitive diagnosis but also the analysis of skills and error. Concerning the selected setting for this diagnostic assessment that develops the combination of cognitive diagnosis, skills analysis and error analysis, the teachers should create an assessment rubric. The rubric plays the important role as the guide to provide a set of criteria for the assessment. Without the precise rubric, the teacher potentially ineffectively documents and follows up the data about students at risk of failure. Furthermore, the teachers who employ the program of Gizmos as the diagnostic assessment might encounter some obstacles. Based on the condition of assessment in the selected setting, the obstacles involve the time constrain, the reluctance of higher teaching burden and the students’ behavior. Consequently, the teacher who chooses the Gizmos with those approaches has to plan, implement and evaluate the assessment. The main point of this assessment is not in the result of students’ worksheet. However, the diagnostic assessment has the two-stage process; the process to prompt and effectively follow-up both individual weaknesses and those of the learning process. Ultimately, the discussion of Gizmos as the media of the diagnostic assessment refers to the effort to improve the mathematical learning process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagnostic%20assessment" title="diagnostic assessment">diagnostic assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20analysis" title=" error analysis"> error analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Gizmos%20online%20program" title=" Gizmos online program"> Gizmos online program</a>, <a href="https://publications.waset.org/abstracts/search?q=skills%20analysis" title=" skills analysis"> skills analysis</a> </p> <a href="https://publications.waset.org/abstracts/58332/the-analysis-of-gizmos-online-program-as-mathematics-diagnostic-program-a-story-from-an-indonesian-private-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58332.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">183</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">27982</span> Tectono-Thermal Evolution of Ningwu-Jingle Basin in North China Craton: Constraints from Apatite (U–Th-Sm)/He and Fission Track Thermochronology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhibin%20Lei">Zhibin Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Minghui%20Yang"> Minghui Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ningwu-Jingle basin is a structural syncline which has undergone a complex tectono-thermal history since Cretaceous. It stretches along the strike of the northern Lvliang Mountains which are the most important mountains in the middle and west of North China Craton. The Mesozoic units make up of the core of Ningwu-Jingle Basin, with pre-Mesozoic units making up of its flanks. The available low-temperature thermochronology implies that Ningwu-Jingle Basin has experienced two stages of uplifting: 94±7Ma to 111±8Ma (Albian to Cenomanian) and 62±4 to 75±5Ma (Danian to Maastrichtian). In order to constrain its tectono-thermal history in the Cenozoic, both apatite (U-Th-Sm)/He and fission track dating analysis are applied on 3 Middle Jurassic and 3 Upper Triassic sandstone samples. The central fission track ages range from 74.4±8.8Ma to 66.0±8.0Ma (Campanian to Maastrichtian) which matches well with previous data. The central He ages range from 20.1±1.2Ma to 49.1±3.0Ma (Ypresian to Burdigalian). Inverse thermal modeling is established based on both apatite fission track data and (U-Th-Sm)/He data. The thermal history obtained reveals that all 6 sandstone samples cross the high-temperature limit of fission track partial annealing zone by the uppermost Cretaceous and that of He partial retention zone by the uppermost Eocene to the early Oligocene. The result indicates that the middle and west of North China Craton is not stable in the Cenozoic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apatite%20fission%20track%20thermochronology" title="apatite fission track thermochronology">apatite fission track thermochronology</a>, <a href="https://publications.waset.org/abstracts/search?q=apatite%20%28u%E2%80%93th%29%2Fhe%20thermochronology" title=" apatite (u–th)/he thermochronology"> apatite (u–th)/he thermochronology</a>, <a href="https://publications.waset.org/abstracts/search?q=Ningwu-Jingle%20basin" title=" Ningwu-Jingle basin"> Ningwu-Jingle basin</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20China%20craton" title=" North China craton"> North China craton</a>, <a href="https://publications.waset.org/abstracts/search?q=tectono-thermal%20history" title=" tectono-thermal history"> tectono-thermal history</a> </p> <a href="https://publications.waset.org/abstracts/60585/tectono-thermal-evolution-of-ningwu-jingle-basin-in-north-china-craton-constraints-from-apatite-u-th-smhe-and-fission-track-thermochronology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60585.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">263</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">27981</span> Quantifying the UK’s Future Thermal Electricity Generation Water Use: Regional Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Murrant">Daniel Murrant</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Quinn"> Andrew Quinn</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Chapman"> Lee Chapman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A growing population has led to increasing global water and energy demand. This demand, combined with the effects of climate change and an increasing need to maintain and protect the natural environment, represents a potentially severe threat to many national infrastructure systems. This has resulted in a considerable quantity of published material on the interdependencies that exist between the supply of water and the thermal generation of electricity, often known as the water-energy nexus. Focusing specifically on the UK, there is a growing concern that the future availability of water may at times constrain thermal electricity generation, and therefore hinder the UK in meeting its increasing demand for a secure, and affordable supply of low carbon electricity. To provide further information on the threat the water-energy nexus may pose to the UK’s energy system, this paper models the regional water demand of UK thermal electricity generation in 2030 and 2050. It uses the strategically important Energy Systems Modelling Environment model developed by the Energy Technologies Institute. Unlike previous research, this paper was able to use abstraction and consumption factors specific to UK power stations. It finds that by 2050 the South East, Yorkshire and Humber, the West Midlands and North West regions are those with the greatest freshwater demand and therefore most likely to suffer from a lack of resource. However, it finds that by 2050 it is the East, South West and East Midlands regions with the greatest total water (fresh, estuarine and seawater) demand and the most likely to be constrained by environmental standards. <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=power%20station%20cooling" title=" power station cooling"> power station cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=UK%20water-energy%20nexus" title=" UK water-energy nexus"> UK water-energy nexus</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20abstraction" title=" water abstraction"> water abstraction</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a> </p> <a href="https://publications.waset.org/abstracts/38686/quantifying-the-uks-future-thermal-electricity-generation-water-use-regional-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38686.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">294</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">27980</span> Self-Supervised Attributed Graph Clustering with Dual Contrastive Loss Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lijuan%20Zhou">Lijuan Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengqi%20Wu"> Mengqi Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Changyong%20Niu"> Changyong Niu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Attributed graph clustering can utilize the graph topology and node attributes to uncover hidden community structures and patterns in complex networks, aiding in the understanding and analysis of complex systems. Utilizing contrastive learning for attributed graph clustering can effectively exploit meaningful implicit relationships between data. However, existing attributed graph clustering methods based on contrastive learning suffer from the following drawbacks: 1) Complex data augmentation increases computational cost, and inappropriate data augmentation may lead to semantic drift. 2) The selection of positive and negative samples neglects the intrinsic cluster structure learned from graph topology and node attributes. Therefore, this paper proposes a method called self-supervised Attributed Graph Clustering with Dual Contrastive Loss constraints (AGC-DCL). Firstly, Siamese Multilayer Perceptron (MLP) encoders are employed to generate two views separately to avoid complex data augmentation. Secondly, the neighborhood contrastive loss is introduced to constrain node representation using local topological structure while effectively embedding attribute information through attribute reconstruction. Additionally, clustering-oriented contrastive loss is applied to fully utilize clustering information in global semantics for discriminative node representations, regarding the cluster centers from two views as negative samples to fully leverage effective clustering information from different views. Comparative clustering results with existing attributed graph clustering algorithms on six datasets demonstrate the superiority of the proposed method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attributed%20graph%20clustering" title="attributed graph clustering">attributed graph clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=contrastive%20learning" title=" contrastive learning"> contrastive learning</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering-oriented" title=" clustering-oriented"> clustering-oriented</a>, <a href="https://publications.waset.org/abstracts/search?q=self-supervised%20learning" title=" self-supervised learning"> self-supervised learning</a> </p> <a href="https://publications.waset.org/abstracts/185262/self-supervised-attributed-graph-clustering-with-dual-contrastive-loss-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185262.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">27979</span> Water-Fluxed Melting and Back-Arc Extension in the Continental Arc: Evidence from I-Type Granites, Adakitic Rocks and High-Nb Basalts at the Western Margin of the Yangtze Block, South China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Huang">B.

Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Neoproterozoic western margin of the Yangtze Block in South China preserves distinctive magmatic associations that record variable water contents and tectonic processes in continental arc settings. Systematic field investigation and detailed petrological studies reveal two distinct magmatic episodes: the Yuanmou Complex (811-802 Ma) and Jinping granites (750 Ma). Through thermodynamic modeling and geochemical analysis, this study demonstrates systematic variations in magma generation controlled by crustal water content at different depths. Phase equilibria modeling indicates the Jinping I-type granites formed through low water-fluxed melting at medium pressure (6-9 kbar), whereas contemporaneous adakitic rocks resulted from high water-flux partial melting of thickened lower crust at high pressure (9-12 kbar). High-Nb basalts in the Yuanmou Complex derived from metasomatized mantle wedge during slab rollback, indicating a back-arc extensional environment. The spatial and temporal relationships between these magmatic rocks constrain the evolution of water content and tectonic setting during continental arc development. Integrated geochemical and isotopic data demonstrate the control of water content on magma generation processes. These findings provide new insights into the mechanisms of crustal growth and reworking in continental arc settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adakitic%20and%20high%20Nb%20mafic%20rocks" title="adakitic and high Nb mafic rocks">adakitic and high Nb mafic rocks</a>, <a href="https://publications.waset.org/abstracts/search?q=back-arc%20extension" title=" back-arc extension"> back-arc extension</a>, <a href="https://publications.waset.org/abstracts/search?q=continental%20Arc" title=" continental Arc"> continental Arc</a>, <a href="https://publications.waset.org/abstracts/search?q=water-fluxed%20melting" title=" water-fluxed melting"> water-fluxed melting</a> </p> <a href="https://publications.waset.org/abstracts/196252/water-fluxed-melting-and-back-arc-extension-in-the-continental-arc-evidence-from-i-type-granites-adakitic-rocks-and-high-nb-basalts-at-the-western-margin-of-the-yangtze-block-south-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/196252.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">7</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">27978</span> The Impact of Audit Committee on Real Earnings Management: Evidence from Netherlands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sana%20Masmoudi">Sana Masmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosra%20Makni"> Yosra Makni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regulators highlight the importance of the Audit Committee (AC) as a key internal corporate governance mechanism. One of the most important roles of this committee is to oversee the financial reporting process. The purpose of this paper is to examine the link between the characteristics of an audit committee and the financial reporting quality by investigating whether the formation of audit committees and their characteristics are associated with improved financial reporting quality. This study provides empirical evidence of the association between audit committee independence, financial expertise, gender diversity, and meetings and Real Earnings Management (REM) as a proxy of financial reporting quality. Using data from, with a sample of 80 companies listed on the Amsterdam Stock Exchange during 2010-2017, the study finds that independence and AC Gender diversity are strongly related to financial reporting quality. In fact, these two characteristics constrain REM. The results also suggest that AC-financial expertise reduces to some extent, the likelihood of engaging in REM. These conclusions provide support then to the audit committee requirement under the Dutch Corporate Governance Code rules regarding gender diversity and AC meetings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit%20committee" title="audit committee">audit committee</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20expertise" title=" financial expertise"> financial expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=independence" title=" independence"> independence</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20earnings%20management" title=" real earnings management"> real earnings management</a> </p> <a href="https://publications.waset.org/abstracts/109923/the-impact-of-audit-committee-on-real-earnings-management-evidence-from-netherlands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109923.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">172</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">27977</span> An Entropy Based Novel Algorithm for Internal Attack Detection in Wireless Sensor Network </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20R.%20Ahmed">Muhammad R.

It is open media and underpinned by an application driven technology for information gathering and processing. It can be used for many different applications range from military implementation in the battlefield, environmental monitoring, health sector as well as emergency response of surveillance. With its nature and application scenario, security of WSN had drawn a great attention. It is known to be valuable to variety of attacks for the construction of nodes and distributed network infrastructure. In order to ensure its functionality especially in malicious environments, security mechanisms are essential. Malicious or internal attacker has gained prominence and poses the most challenging attacks to WSN. Many works have been done to secure WSN from internal attacks but most of it relay on either training data set or predefined threshold. Without a fixed security infrastructure a WSN needs to find the internal attacks is a challenge. In this paper we present an internal attack detection method based on maximum entropy model. The final experimental works showed that the proposed algorithm does work well at the designed level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20attack" title="internal attack">internal attack</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20security" title=" network security"> network security</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a> </p> <a href="https://publications.waset.org/abstracts/26980/an-entropy-based-novel-algorithm-for-internal-attack-detection-in-wireless-sensor-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26980.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">456</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">27976</span> Zonal and Sequential Extraction Design for Large Flat Space to Achieve Perpetual Tenability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mingjun%20Xu">Mingjun Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Man%20Pun%20Wan"> Man Pun Wan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study proposed an effective smoke control strategy for the large flat space with a low ceiling to achieve the requirement of perpetual tenability. For the large flat space with a low ceiling, the depth of the smoke reservoir is very shallow, and it is difficult to perpetually constrain the smoke within a limited space. A series of numerical tests were conducted to determine the smoke strategy. A zonal design i.e., the fire zone and two adjacent zones was proposed and validated to be effective in controlling smoke. Once a fire happens in a compartment space, the Engineered Smoke Control (ESC) system will be activated in three zones i.e., the fire zone, in which the fire happened, and two adjacent zones. The smoke can be perpetually constrained within the three smoke zones. To further improve the extraction efficiency, sequential activation of the ESC system within the 3 zones turned out to be more efficient than simultaneous activation. Additionally, the proposed zonal and sequential extraction design can reduce the mechanical extraction flow rate by up to 40.7 % as compared to the conventional method, which is much more economical than that of the conventional method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance-based%20design" title="performance-based
