Such compliant mechanisms like the flex-run require the knowledge of their dynamic response and deformation behavior under quickly varying loads. The modeling of finite deformations of the compliant athletic system is described by Neo-Hookean model under contact-impact conditions. The dynamic impact-contact governing equations for both the target and impactor are derived based on the updated Lagrangian approach. A method where contactor and target are considered as a united body is applied in the formulation of the principle of virtual work for the bodies. In this paper, methods of continuum mechanics and nonlinear finite element method were deployed to develop a model that could capture the behavior of the compliant athletic system under quickly varying loads. A hybrid system of symbolic algebra (AceGEN) and a compiled back end (AceFEM) were employed, leveraging both ease of use and computational efficiency. The simulated results reveal the effect of the various contact-impact conditions on the deformation behavior of the impacting compliant mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eigenvalue%20problems" title="eigenvalue problems">eigenvalue problems</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=robin%20boundary%20condition" title=" robin boundary condition"> robin boundary condition</a>, <a href="https://publications.waset.org/abstracts/search?q=sturm-liouville%20problem" title=" sturm-liouville problem"> sturm-liouville problem</a> </p> <a href="https://publications.waset.org/abstracts/37921/contact-impact-analysis-of-continuum-compliant-athletic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37921.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">473</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">6</span> Investigating the Determinants and Growth of Financial Technology Depth of Penetration among the Heterogeneous Africa Economies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tochukwu%20Timothy%20Okoli">Tochukwu Timothy Okoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Devi%20Datt%20Tewari"> Devi Datt Tewari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high rate of Fintech adoption has not transmitted to greater financial inclusion and development in Africa. This problem is attributed to poor Fintech diversification and usefulness in the continent. This concept is referred to as the Fintech depth of penetration in this study. The study, therefore, assessed its determinants and growth process in a panel of three emergings, twenty-four frontiers and five fragile African economies disaggregated with dummies over the period 2004-2018 to allow for heterogeneity between groups. The System Generalized Method of Moments (GMM) technique reveals that the average depth of Mobile banking and automated teller machine (ATM) is a dynamic heterogeneity process. Moreover, users' previous experiences/compatibility, trial-ability/income, and financial development were the major factors that raise its usefulness, whereas perceived risk, financial openness, and inflation rate significantly limit its usefulness. The growth rate of Mobile banking, ATM, and Internet banking in 2018 is, on average 41.82, 0.4, and 20.8 per cent respectively greater than its average rates in 2004. These greater averages after the 2009 financial crisis suggest that countries resort to Fintech as a risk-mitigating tool. This study, therefore, recommends greater Fintech diversification through improved literacy, institutional development, financial liberalization, and continuous innovation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depth%20of%20fintech" title="depth of fintech">depth of fintech</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20Africa" title=" emerging Africa"> emerging Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20technology" title=" financial technology"> financial technology</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20banking" title=" internet banking"> internet banking</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20banking" title=" mobile banking "> mobile banking </a> </p> <a href="https://publications.waset.org/abstracts/128050/investigating-the-determinants-and-growth-of-financial-technology-depth-of-penetration-among-the-heterogeneous-africa-economies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128050.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">130</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">5</span> Development of Medical Intelligent Process Model Using Ontology Based Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Chibuogu%20Asogwa">Emmanuel Chibuogu Asogwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Tochukwu%20Sunday%20Belonwu"> Tochukwu Sunday Belonwu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An urgent demand for creative solutions has been created by the rapid expansion of medical knowledge, the complexity of patient care, and the requirement for more precise decision-making. As a solution to this problem, the creation of a Medical Intelligent Process Model (MIPM) utilizing ontology-based appears as a promising way to overcome this obstacle and unleash the full potential of healthcare systems. The development of a Medical Intelligent Process Model (MIPM) using ontology-based techniques is motivated by a lack of quick access to relevant medical information and advanced tools for treatment planning and clinical decision-making, which ontology-based techniques can provide. The aim of this work is to develop a structured and knowledge-driven framework that leverages ontology, a formal representation of domain knowledge, to enhance various aspects of healthcare. Object-Oriented Analysis and Design Methodology (OOADM) were adopted in the design of the system as we desired to build a usable and evolvable application. For effective implementation of this work, we used the following materials/methods/tools: the medical dataset for the test of our model in this work was obtained from Kaggle. The ontology-based technique was used with Confusion Matrix, MySQL, Python, Hypertext Markup Language (HTML), Hypertext Preprocessor (PHP), Cascaded Style Sheet (CSS), JavaScript, Dreamweaver, and Fireworks. According to test results on the new system using Confusion Matrix, both the accuracy and overall effectiveness of the medical intelligent process significantly improved by 20% compared to the previous system. Therefore, using the model is recommended for healthcare professionals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ontology-based" title="ontology-based">ontology-based</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=database" title=" database"> database</a>, <a href="https://publications.waset.org/abstracts/search?q=OOADM" title=" OOADM"> OOADM</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a> </p> <a href="https://publications.waset.org/abstracts/172652/development-of-medical-intelligent-process-model-using-ontology-based-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172652.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Aeromagnetic Data Interpretation and Source Body Evaluation Using Standard Euler Deconvolution Technique in Obudu Area, Southeastern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chidiebere%20C.%20Agoha">Chidiebere C.

Data analysis and enhancement techniques, including reduction to the equator, horizontal derivative, first and second vertical derivatives, upward continuation and regional-residual separation, were carried out for the purpose of detailed data Interpretation. Standard Euler deconvolution for structural indices of 0, 1, 2, and 3 was also carried out and respective maps were obtained using the Euler deconvolution algorithm. Results show that the total magnetic intensity ranges from -122.9nT to 147.0nT, regional intensity varies between -106.9nT to 137.0nT, while residual intensity ranges between -51.5nT to 44.9nT clearly indicating the masking effect of deep-seated structures over surface and shallow subsurface magnetic materials. Results also indicated that the positive residual anomalies have an NE-SW orientation, which coincides with the trend of major geologic structures in the area. Euler deconvolution for all the considered structural indices has depth to magnetic sources ranging from the surface to more than 2000m. Interpretation of the various structural indices revealed the locations and depths of the source bodies and the existence of geologic models, including sills, dykes, pipes, and spherical structures. This area is characterized by intrusive and very shallow basement materials and represents an excellent prospect for solid mineral exploration and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euler%20deconvolution" title="Euler deconvolution">Euler deconvolution</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20derivative" title=" horizontal derivative"> horizontal derivative</a>, <a href="https://publications.waset.org/abstracts/search?q=Obudu" title=" Obudu"> Obudu</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20indices" title=" structural indices"> structural indices</a> </p> <a href="https://publications.waset.org/abstracts/171696/aeromagnetic-data-interpretation-and-source-body-evaluation-using-standard-euler-deconvolution-technique-in-obudu-area-southeastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171696.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">81</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">3</span> Reconnaissance Investigation of Thermal Springs in the Middle Benue Trough, Nigeria by Remote Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Tochukwu">N.

Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is no new that Nigeria faces a continual power shortage problem due to its vast population power demand and heavy reliance on nonrenewable forms of energy such as thermal power or fossil fuel. Many researchers have recommended using geothermal energy as an alternative; however, Past studies focus on the geophysical & geochemical investigation of this energy in the sedimentary and basement complex; only a few studies incorporated the remote sensing methods. Therefore, in this study, the preliminary examination of geothermal resources in the Middle Benue was carried out using satellite imagery in ArcMap. Landsat 8 scene (TIR, NIR, Red spectral bands) was used to estimate the Land Surface Temperature (LST). The Maximum Likelihood Classification (MLC) technique was used to classify sites with very low, low, moderate, and high LST. The intermediate and high classification happens to be possible geothermal zones, and they occupy 49% of the study area (38077km2). Riverline were superimposed on the LST layer, and the identification tool was used to locate high temperate sites. Streams that overlap on the selected sites were regarded as geothermal springs as. Surprisingly, the LST results show lower temperatures (<36°C) at the famous thermal springs (Awe & Wukari) than some unknown rivers/streams found in Kwande (38°C), Ussa, (38°C), Gwer East (37°C), Yola Cross & Ogoja (36°C). Studies have revealed that temperature increases with depth. However, this result shows excellent geothermal resources potential as it is expected to exceed the minimum geothermal gradient of 25.47 with an increase in depth. Therefore, further investigation is required to estimate the depth of the causative body, geothermal gradients, and the sustainability of the reservoirs by geophysical and field exploration. This method has proven to be cost-effective in locating geothermal resources in the study area. Consequently, the same procedure is recommended to be applied in other regions of the Precambrian basement complex and the sedimentary basins in Nigeria to save a preliminary field survey cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ArcMap" title="ArcMap">ArcMap</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal%20resources" title=" geothermal resources"> geothermal resources</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat%208" title=" Landsat 8"> Landsat 8</a>, <a href="https://publications.waset.org/abstracts/search?q=LST" title=" LST"> LST</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20springs" title=" thermal springs"> thermal springs</a>, <a href="https://publications.waset.org/abstracts/search?q=MLC" title=" MLC"> MLC</a> </p> <a href="https://publications.waset.org/abstracts/142625/reconnaissance-investigation-of-thermal-springs-in-the-middle-benue-trough-nigeria-by-remote-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142625.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">190</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">2</span> Alternation of Executive Power and Democratic Governance in Nigeria: The Role of Independent National Electoral Commission, 1999-2014</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Tochukwu%20Omenma">J. Tochukwu Omenma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Buzzword in Nigeria is that democracy has “come to stay”. Politicians in their usual euphoria consider democracy as already consolidated in the country. Politicians linked this assumption to three fundamental indicators – (a) multiparty system; (b) regular elections and (c) absence of military coup after 15 years of democracy in Nigeria. Beyond this assumption, we intend to empirically verify these claims and assumptions, by relying on Huntington’s conceptualization of democratic consolidation. Though, Huntington asserts that multipartism, regular elections and absence of any major obstacle leading to reversal of democracy are significant indicators of democratic consolidation, but the presence of those indicators must result to alternation of executive power for democratic consolidation to occur. In other words, regular conduct of election and existence of multiple political parties are not enough for democratic consolidation, rather free and fair elections. Past elections were characterized of massive fraud and irregularities casting doubts on integrity of electoral management body (EMB) to conduct free and fair elections in Nigeria. There are three existing perspectives that have offered responses to the emasculation of independence of EMB. One is a more popular position indicating that the incumbent party, more than the opposition party, influence the EMB activities with the aim of rigging elections; the other is a more radical perspective that suggests that weakening of EMB power is more associated with the weakest party than with the incumbent; and the last, is that godfather(s) are in direct control of EMB members thereby controlling the process of electoral process to the advantage of the godfather(s). With empirical evidence sourced from the reports of independent election monitors, (European Union, Election Observation Mission in Nigeria) this paper shows at different electoral periods that, in terms of influencing election outcomes, the incumbent and godfather have been more associated with influencing election results than the opposition. The existing nature of executive power in Nigeria provides a plausible explanation for the incumbent’s overbearing influence thereby limiting opportunity for free and fair elections and by extension undermining the process of democratic consolidation in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20party" title="political party">political party</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=democratic%20consolidation" title=" democratic consolidation"> democratic consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=election" title=" election"> election</a>, <a href="https://publications.waset.org/abstracts/search?q=godfatherism" title=" godfatherism"> godfatherism</a> </p> <a href="https://publications.waset.org/abstracts/18396/alternation-of-executive-power-and-democratic-governance-in-nigeria-the-role-of-independent-national-electoral-commission-1999-2014" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18396.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">491</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">1</span> Effect of Tissue Preservation Chemicals on Decomposition in Different Soil Types</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onyekachi%20Ogbonnaya%20Iroanya">Onyekachi Ogbonnaya Iroanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Taiye%20Abdullahi%20Gegele"> Taiye Abdullahi Gegele</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Tochukwu%20Egwuatu"> Frank Tochukwu Egwuatu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Forensic taphonomy is a multifaceted area that incorporates decomposition, chemical and biological cadaver exposure in post-mortem event chronology and reconstruction to predict the Post Mortem Interval (PMI). The aim of this study was to evaluate the integrity of DNA extracted from the remains of embalmed decomposed Sus domesticus tissues buried in different soil types. Method: A total of 12 limbs of Sus domesticus weighing between 0.7-1.4 kg were used. Each of the samples across the groups was treated with 10% formaldehyde, absolute methanol and 50% Pine oil for 24 hours before burial except the control samples, which were buried immediately. All samples were buried in shallow simulated Clay, Sandy and Loamy soil graves for 12 months. The DNA for each sample was extracted and quantified with Nanodrop Spectrophotometer (6305 JENWAY spectrometers). The rate of decomposition was examined through the modified qualitative decomposition analysis. Extracted DNA was amplified through PCR and bands visualized via gel electrophoresis. A biochemical enzyme assay was done for each burial grave soil. Result: The limbs in all burial groups had lost weight over the burial period. There was a significant increase in the soil urease level in the samples preserved in formaldehyde across the 3 soil type groups (p≤0.01). Also, the control grave soils recorded significantly higher alkaline phosphatase, dehydrogenase and calcium carbonate values compared to experimental grave soils (p≤0.01). The experimental samples showed a significant decrease in DNA concentration and purity when compared to the control groups (p≤0.01). Obtained findings of the soil biochemical analysis showed the embalming treatment altered the relationship between organic matter decomposition and soil biochemical properties as observed in the fluctuations that were recorded in the soil biochemical parameters. The PCR amplified DNA showed no bands on the gel electrophoresis plates. Conclusion: In criminal investigations, factors such as burial grave soil, grave soil biochemical properties, antemortem exposure to embalming chemicals should be considered in post-mortem interval (PMI) determination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20taphonomy" title="forensic taphonomy">forensic taphonomy</a>,
