lecturers in a tertiary institution in Nigeria is one of the determinants of the lecturer’s productivity. In this study, therefore, lecturers’ teaching effectiveness was examined vis-à-vis their multimedia technologies utilisation in Colleges of Education (CoE) in South-West, Nigeria. This is for the purpose of ascertaining the relationship and contribution of multimedia technologies utilisation to lecturers’ teaching effectiveness in Nigerian colleges of education. The descriptive survey research design was adopted in the study, while a multi-stage sampling procedure was used in the study. A stratified sampling technique was used to select colleges of education, and a simple random sampling method was employed to select lecturers from the selected colleges of education. A total of 862 lecturers (627 males and 235 females) were selected from the colleges of education used for the study. The instrument used was lecturers’ questionnaire on multimedia technologies utilisation and teaching effectiveness with a reliability coefficient of 0.85 at 0.05 level of significance. The data collected were analysed using descriptive statistics, multiple regression, and t-test. The findings showed that the level of multimedia technologies utilisation in colleges of education was low, whereas lecturers’ teaching effectiveness was high. Findings also revealed that the lecturers used multimedia technologies purposely for personal and professional developments, so also for up to date news on economic and political matters. Also, findings indicated that laptop, Ipad, CD-ROMs, and computer instructional software were the multimedia technologies frequently utilised by the lecturers. There was also a significant difference in the teaching effectiveness between lecturers in the Federal and State COE. The government should, therefore, make adequate provision for multimedia technologies in the COE in Nigeria for lecturers’ utilisation in their instructions so as to boost their students’ learning outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colleges%20of%20education" title="colleges of education">colleges of education</a>, <a href="https://publications.waset.org/abstracts/search?q=lecturers%E2%80%99%20teaching%20effectiveness" title=" lecturers’ teaching effectiveness"> lecturers’ teaching effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=multimedia%20technologies%20utilisation" title=" multimedia technologies utilisation"> multimedia technologies utilisation</a>, <a href="https://publications.waset.org/abstracts/search?q=Southwest%20Nigeria" title=" Southwest Nigeria"> Southwest Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/112117/multimedia-technologies-utilisation-as-predictors-of-lecturers-teaching-effectiveness-in-colleges-of-education-in-south-west-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112117.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Criss-Crossing the Sahara: New Dangers to the Ambitions of West African Migrants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20Paul%20Adesanya">Olusegun Paul Adesanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwatomilade%20Olominu"> Oluwatomilade Olominu</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20Idowu"> Olusegun Idowu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates new dangers that West African migrants travelling through the Sahara Desert to Europe contend with. COVID-19 has left an unprecedented impact on all aspects of global politics, migration inclusive. In turn, limitations to migration have drastically increased, especially the stricter visa application measures set by European countries. This intensified attempts at crisscrossing the desert to Europe. In turn, several migrants used the Sahara as the highway to Europe. While some persons successfully travelled through the desert-scape, several others were unsuccessful. Notwithstanding the negative experiences of previous migrants, several other nationals across the region have plans to travel through the desert to Europe. As such, this study employs a mixed method of research reliant on qualitative and quantitative methods of data gathering and analysis. The study holds that there are new dangers to the aspirations of West Africans travelling to Europe through the Sahara and the Mediterranean Sea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=migrants" title="migrants">migrants</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahara%20Desert" title=" Sahara Desert"> Sahara Desert</a>, <a href="https://publications.waset.org/abstracts/search?q=West%20Africa" title=" West Africa"> West Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=crisscrossing" title=" crisscrossing"> crisscrossing</a>, <a href="https://publications.waset.org/abstracts/search?q=dangers" title=" dangers"> dangers</a>, <a href="https://publications.waset.org/abstracts/search?q=irregular%20migration" title=" irregular migration"> irregular migration</a> </p> <a href="https://publications.waset.org/abstracts/157723/criss-crossing-the-sahara-new-dangers-to-the-ambitions-of-west-african-migrants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157723.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">220</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">50</span> Constant Order Predictor Corrector Method for the Solution of Modeled Problems of First Order IVPs of ODEs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20James">A.

The population of the study comprised 198 primary school pupils in three selected schools in Ogun State, Nigeria. Data were collected through questionnaire and were analysed with the use of multiple regression and ANOVA to analysed the correlation between class-size, instructional materials (independent variables) and learning achievement (dependent variable). The findings revealed that schools having an average class-size of 30 and below with use of instructional materials obtained better results than schools having more than 30 and above. The main score were higher in the school in schools having 30 and below than schools with 30 and above. It was therefore recommended that government, stakeholders and NGOs should provide more classrooms and supply of adequate instructional materials in all primary schools in the state to cater for small class-size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=class-size" title="class-size">class-size</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20materials" title=" instructional materials"> instructional materials</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement "> academic achievement </a> </p> <a href="https://publications.waset.org/abstracts/10419/class-size-and-instructional-materials-as-correlates-of-pupils-learning-and-academic-achievement-in-primary-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10419.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> The Use of Substances and Sports Performance among Youth: Implications for Lagos State Sports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osifeko%20Olalekan%20Remigious">Osifeko Olalekan Remigious</a>, <a href="https://publications.waset.org/abstracts/search?q=Adesanya%20Adebisi%20Joseph"> Adesanya Adebisi Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Omolade%20Akinmade%20Olatunde"> Omolade Akinmade Olatunde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this study was to determine the factors associated with the use of substances for sport performance of youth in Lagos state sport.

Therefore, there is need to determine the actual rate of settlement possible in the soil before structures are built on it. This information will help in determining the type of foundation design and the kind of reinforcement that will be necessary in constructions. This paper presents a simplified and a faster approach for determining foundation settlement in any type of soil using real field data acquired from seismic refraction techniques and cone penetration tests. This approach was also able to determine the depth of settlement of each strata of soil. The results obtained revealed the different settlement time and depth of settlement possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heterogeneous" title="heterogeneous">heterogeneous</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=foundation" title=" foundation"> foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=technique" title=" technique"> technique</a> </p> <a href="https://publications.waset.org/abstracts/37473/foundation-settlement-determination-a-simplified-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37473.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">445</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">46</span> Analysis of Generated Biogas from Anaerobic Digestion of Piggery Dung</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Babatope%20Alabadan">Babatope Alabadan</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeyinka%20Adesanya"> Adeyinka Adesanya</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20E.%20Afangideh"> I.

Over the years, different sources of energy (petroleum fuels predominantly) have been utilized. Animal waste treatment on the farm is a phenomenon that has called for rapt research attention. Generated wastes on farm pollute the environment in diverse ways. Waste-to-bioenergy treatments can provide livestock operators with multiple value-added, renewable energy products. The objective of this work is to generate methane (CH4) gas from the anaerobic digestion of piggery dung. A retention time of 15 and 30 days and a mesophilic temperature range were selected. The generated biogas composition was methane (CH4), carbondioxide (CO2), hydrogen sulphide (H2S) and ammonia (NH3) using gas chromatography method. At 15 days retention time, 60% of (CH4) was collected while CO2 and traces of H2S and NH3 accounted for 40%. At 30 days retention time, 75% of CH4, 20% of CO2 was collected while traces of H2S and NH3 amounted to 5%. For on and off farm uses, biogas can be upgraded to biomethane by removing the CO2, NH3 and H2S. This product (CH4) can meet heating and power needs or serve as transportation fuels <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=methane" title=" methane"> methane</a>, <a href="https://publications.waset.org/abstracts/search?q=piggery%20dung" title=" piggery dung"> piggery dung</a> </p> <a href="https://publications.waset.org/abstracts/66260/analysis-of-generated-biogas-from-anaerobic-digestion-of-piggery-dung" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66260.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">345</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">45</span> Transverse Vibration of Elastic Beam Resting on Variable Elastic Foundation Subjected to moving Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Idowu%20Ibikunle%20Albert">Idowu Ibikunle Albert</a>, <a href="https://publications.waset.org/abstracts/search?q=Atilade%20Adesanya%20Oluwafemi"> Atilade Adesanya Oluwafemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Okedeyi%20Abiodun%20Sikiru"> Okedeyi Abiodun Sikiru</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Rilwan%20Adewale"> Mustapha Rilwan Adewale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> These present-day all areas of transport have experienced large advances characterized by increases in the speeds and weight of vehicles. As a result, this paper considered the Transverse Vibration of an Elastic Beam Resting on a Variable Elastic Foundation Subjected to a moving Load. The beam is presumed to be uniformly distributed and has simple support at both ends. The moving distributed moving mass is assumed to move with constant velocity. The governing equations, which are fourth-order partial differential equations, were reduced to second-order partial differential equations using an analytical method in terms of series solution and solved by a numerical method using mathematical software (Maple). Results show that an increase in the values of beam parameters, moving Mass M, and k-stiffness K, significantly reduces the deflection profile of the vibrating beam. In the results, it was equally found that moving mass is greater than moving force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20beam" title="elastic beam">elastic beam</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20load" title=" moving load"> moving load</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20of%20structure" title=" response of structure"> response of structure</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20elastic%20foundation" title=" variable elastic foundation"> variable elastic foundation</a> </p> <a href="https://publications.waset.org/abstracts/159577/transverse-vibration-of-elastic-beam-resting-on-variable-elastic-foundation-subjected-to-moving-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159577.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">121</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">44</span> Mathematical Analysis of Matrix and Filler Formulation in Composite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20A.%20Afolabi">Olusegun A.

Unless these pupils are recognised and treated, they are likely to become educational discards. This study consequently attempted to determine effects of self-monitoring strategy on homework completion among pupils with learning disabilities. Ninety (90) participants were engaged in the study. Pre-test, post-test, control group quasi experimental design was adopted. Purposive sampling technique was used to select pupils with evidence of learning disabilities from three primary schools in Ondo State. Findings showed that self-monitoring strategy was significant in enhancing homework completion among pupils with learning disabilities. However, gender and self-esteem did not significantly contribute to homework completion. The study therefore recommended that measures such that would uncover unsettling academic, psychological and emotional deficiencies of these pupils through appropriate diagnosis should be undertaken by the parents and teachers, in order for them to have a sense of belonging in the society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self%20monitoring" title="self monitoring">self monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20work%20completion" title=" home work completion"> home work completion</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20dissabilities" title=" learning dissabilities"> learning dissabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a> </p> <a href="https://publications.waset.org/abstracts/70656/use-of-self-monitoring-strategy-on-homework-completion-among-pupils-with-learning-disabilities-in-ondo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70656.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">352</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">39</span> The Potential for Recycling Household Wastes Generated from the Residential Areas of Obafemi Awolowo University, Ile-Ife</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asaolu%20Olugbenga%20Stephen">Asaolu Olugbenga Stephen</a>, <a href="https://publications.waset.org/abstracts/search?q=Afolabi%20Olusegun%20Temitope"> Afolabi Olusegun Temitope</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lack of proper solid waste management is one of the main causes of environmental pollution and degradation in many cities, especially in developing countries. The aim of this study was to estimate the quantity of waste generated per capita per day, determine the composition and identify the potentials for recycling of waste generated. Characterization of wastes from selected households in the residential areas was done for over a 7 day period. The weight of each sorted category of waste was recorded in a structured database that calculated the proportion of each waste component. The results indicated that 85.4% of the sampled waste characterized was found to be recyclable; with an estimated average waste generated of 1.82kg/capita/day. The various solid waste fractions were organic (64.6%), plastics (15.6%), metals (9.2%), glass materials (1.6%) and unclassified (8.9%). It was concluded from this study that a large proportion of the waste generated from OAU campus residential area was recyclable and that there is a need to enact policy on waste recycling within the university campus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycling" title="recycling">recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20wastes" title=" household wastes"> household wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=residential" title=" residential"> residential</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste%20management" title=" solid waste management"> solid waste management</a> </p> <a href="https://publications.waset.org/abstracts/35534/the-potential-for-recycling-household-wastes-generated-from-the-residential-areas-of-obafemi-awolowo-university-ile-ife" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35534.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">401</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">38</span> Statistical Time-Series and Neural Architecture of Malaria Patients Records in Lagos, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akinbo%20Razak%20Yinka">Akinbo Razak Yinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Adesanya%20Kehinde%20Kazeem"> Adesanya Kehinde Kazeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Oladokun%20Oluwagbenga%20Peter"> Oladokun Oluwagbenga Peter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Time series data are sequences of observations collected over a period of time. Such data can be used to predict health outcomes, such as disease progression, mortality, hospitalization, etc. The Statistical approach is based on mathematical models that capture the patterns and trends of the data, such as autocorrelation, seasonality, and noise, while Neural methods are based on artificial neural networks, which are computational models that mimic the structure and function of biological neurons. This paper compared both parametric and non-parametric time series models of patients treated for malaria in Maternal and Child Health Centres in Lagos State, Nigeria. The forecast methods considered linear regression, Integrated Moving Average, ARIMA and SARIMA Modeling for the parametric approach, while Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM) Network were used for the non-parametric model. The performance of each method is evaluated using the Mean Absolute Error (MAE), R-squared (R2) and Root Mean Square Error (RMSE) as criteria to determine the accuracy of each model. The study revealed that the best performance in terms of error was found in MLP, followed by the LSTM and ARIMA models.

Lignocellulosic biomass is an excellent renewable feedstock because it is both abundant and inexpensive. This project aims at producing bioethanol from lignocellulosic plants (Sorghum Arundinacieum and Heteropogon Contortus) by biochemical means, computing the energy audit of the process and determining the fuel properties of the produced ethanol. Acid pretreatment (0.5% H2SO4 solution) and enzymatic hydrolysis (using malted barley as enzyme source) were employed. The ethanol yield of wild sorghum was found to be 20% while that of spear grass was 15%. The fuel properties of the bioethanol from wild sorghum are 1.227 centipoise for viscosity, 1.10 g/cm3 for density, 0.90 for specific gravity, 78 °C for boiling point and the cloud point was found to be below -30 °C. That of spear grass was 1.206 centipoise for viscosity, 0.93 g/cm3 for density 1.08 specific gravity, 78 °C for boiling point and the cloud point was also found to be below -30 °C. The energy audit shows that about 64 % of the total energy was used up during pretreatment, while product recovery which was done manually demanded about 31 % of the total energy. Enzymatic hydrolysis, fermentation, and distillation total energy input were 1.95 %, 1.49 % and 1.04 % respectively, the alcoholometric strength of bioethanol from wild sorghum was found to be 47 % and the alcoholometric strength of bioethanol from spear grass was 72 %.

Deep convective systems are investigated over seven climatic zones of the West African sub-region, which are; west-coast rainforest, dry rainforest, Nigeria-Cameroon rainforest, Nigeria savannah, Central African and South Sudan (CASS) Savannah, Sudano-Sahel, and Sahel, using data from Tropical Rainfall Measurement Mission (TRMM) Precipitation Feature (PF) database. The vertical structure of the convective systems indicated by the presence of at least one 40 dBZ and reaching (attaining) at least 1km in the atmosphere showed strong core (highest frequency (%)) of reflectivity values around 2 km which is below the freezing level (4-5km) for all the zones. Echoes are detected above the 15km altitude much more frequently in the rainforest and Savannah zones than the Sudano and Sahel zones during active periods in March-May (MAM), whereas during active periods in June-September (JJAS) the savannahs, Sudano and Sahel zones convections tend to reach higher altitude more frequently than the rainforest zones. The percentage frequencies of deep convection indicated that the occurrences of the systems are within the range of 2.3-2.8% during both March-May (MAM) and June-September (JJAS) active periods in the rainforest and savannah zones. On the contrary, the percentage frequencies were found to be less than 2% in the Sudano and Sahel zones, except during the active-JJAS period in the Sudano zone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20periods" title="active periods">active periods</a>, <a href="https://publications.waset.org/abstracts/search?q=convective%20system" title=" convective system"> convective system</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=reflectivity" title=" reflectivity"> reflectivity</a> </p> <a href="https://publications.waset.org/abstracts/101206/vertical-structure-and-frequencies-of-deep-convection-during-active-periods-of-the-west-african-monsoon-season" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101206.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> A Gyro-stabilized Autonomous Multi-terrain Quadrupedal-wheeled Robot: Towards Edge-enabled Self-balancing, Autonomy, and Terramechanical Efficiency of Unmanned Off-road Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mbadiwe%20S.%20Benyeogor">Mbadiwe S.

This paper proposes an autonomous robot with a gyro-stabilized active suspension system in form of a hybrid quadrupedal wheel drive mechanism. This system is to serve as a miniature model for demonstrating how off-road vehicles can be robotized into efficient terramechanical mobile platforms that are capable of self-balanced autonomous navigation and maneuvering on rough and uneven topographies. Results from tests and analysis show that the developed system performs as expected. Therefore, our model and control devices can be adapted to computerizing, automating, and upgrading the operation of unmanned ground vehicles for off-road navigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20suspension" title="active suspension">active suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20robots" title=" autonomous robots"> autonomous robots</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20computing" title=" edge computing"> edge computing</a>, <a href="https://publications.waset.org/abstracts/search?q=navigational%20sensors" title=" navigational sensors"> navigational sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=terramechanics" title=" terramechanics"> terramechanics</a> </p> <a href="https://publications.waset.org/abstracts/144497/a-gyro-stabilized-autonomous-multi-terrain-quadrupedal-wheeled-robot-towards-edge-enabled-self-balancing-autonomy-and-terramechanical-efficiency-of-unmanned-off-road-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144497.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">154</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">30</span> The Vicissitudes of Monetary Policy Rates and Macro-Economic Variables in the West African Monetary Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Olusegun%20Famoroti">Jonathan Olusegun Famoroti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathew%20Ekundayo%20Rotimi"> Mathew Ekundayo Rotimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mishelle%20Doorasamy"> Mishelle Doorasamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study offers an empirical investigation into some selected macroeconomic drivers of the monetary policy rate in member countries of the West African Monetary Zone (WAMZ), considering both internal and external variables. We employed Autoregressive Distributed Lag (ARDL) to carry out the investigation between monetary policy and some macroeconomic variables in both the long-run and short-run relationship. The results suggest that the drivers of the policy rate in this zone, in the long run, include, among others, global oil price, exchange rate, inflation rate, and gross domestic product, while in the short run, federal fund rate, trade openness, exchange rate, inflation rate, and gross domestic product are core determinants of the policy rate. Therefore, in order to ensure long-run stability in the policy rate among the members’ states, these drivers should be given closer consideration so that the trajectory for effective structure can be designed and fused into the economic structure and policy frameworks accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monetary%20policy%20rate" title="monetary policy rate">monetary policy rate</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic%20variables" title=" macroeconomic variables"> macroeconomic variables</a>, <a href="https://publications.waset.org/abstracts/search?q=WAMZ" title=" WAMZ"> WAMZ</a>, <a href="https://publications.waset.org/abstracts/search?q=ARDL" title=" ARDL"> ARDL</a> </p> <a href="https://publications.waset.org/abstracts/182453/the-vicissitudes-of-monetary-policy-rates-and-macro-economic-variables-in-the-west-african-monetary-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182453.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">65</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">29</span> Monetary Policy and Economic Growth in West African Business Cycles: Markov Switching Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omolade%20Adeleke">Omolade Adeleke</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Olusegun%20Famoroti"> Jonathan Olusegun Famoroti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study empirically examined the monetary policy and economic growth in the classical cycles in 8 member countries of the West African Economic and Monetary Union (WAEMU), using the Markov switching model for the Two-phase Regime, covering the period 1980Q1 to 2020Q4. Our estimates suggest that these countries demonstrate to have similar business cycles, and the economies stay more in an expansion regime than a recession regime. The result further shows that the union has an average duration period of 3.1 and 15.9 quarters for contraction and expansion periods, respectively. The business cycle duration, on average, suggests 19 quarters, varying from country to country. Therefore, the formulation of policies that can enhance aggregate demand by member countries in the union is an antidote for recession and is necessary to drive the economy into equilibrium. Also, a low-interest rate and reduced inflation rate would ginger long-run economic growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monetary%20policy" title="monetary policy">monetary policy</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20cycle" title=" business cycle"> business cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20switching" title=" Markov switching"> Markov switching</a> </p> <a href="https://publications.waset.org/abstracts/167724/monetary-policy-and-economic-growth-in-west-african-business-cycles-markov-switching-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167724.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">75</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">28</span> Relationship of Teachers' Personality and Peer Pressure on Adolescents' Personality Development in Mainland Local Government Area, Lagos State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solomon%20Olusegun%20Olugbenro">Solomon Olusegun Olugbenro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to ascertain the relationship of teachers' personalty and peer pressure on adolescents' personalty in mainland local government, Lagos State, Nigeria.

While Green Infrastructure (GI) is promoted as a strategy to manage ecosystems’ functionality, the extent to which residents are aware of GI types which serve as alternatives to conventional landscapes to be conserved remains unclear. This paper examines the awareness level of GI types among residents of Lagos Metropolis, Nigeria and the association of their demographic characteristics with the level of awareness. Multi-stage sampling technique was used to select 1560 residents who completed semi-structured questionnaires. Descriptive statistics were used to explore data distributions while t-test assessed the differences in the awareness level of the male and female participants. From the 23 different types of GI facilities identified in the study area, residents reported a high level of awareness on just five of them. These include green gardens, green parks, grasses, street trees, and sports fields but a low level of awareness of the remaining 18 GI types. Awareness of GI types is presently low in the study area. Increased awareness will encourage care and protection of green infrastructure by residents which will consequently enhance availability and conservation of more biodiversity in Lagos, Nigeria, and other nations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=awareness" title="awareness">awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity%20conservation" title=" biodiversity conservation"> biodiversity conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20sustainability" title=" environmental sustainability"> environmental sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20infrastructure" title=" green infrastructure"> green infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20centres" title=" urban centres"> urban centres</a> </p> <a href="https://publications.waset.org/abstracts/108288/residents-awareness-of-green-infrastructure-types-in-the-neighbourhood-panacea-for-biodiversity-conservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108288.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">214</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">26</span> Analysis of Geotechnical Parameters from Geophysical Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adewoyin%20O.%20Olusegun">Adewoyin O.

Another factor that can discourage a developer is the fact that most of the geotechnical tests procedures utilized during site investigations, to a certain extent, alter the existing environment of the site. This study suggests a quick, non-destructive and non-intrusive method of obtaining key subsoil geotechnical properties necessary for foundation design for proposed engineering facilities. Seismic wave velocities generated from near surface refraction method was used to determine the bulk density of soil, Young’s modulus, bulk modulus, shear modulus and allowable bearing capacity of a competent layer that can bear structural load at the particular study site. Also, regression equations were developed in order to directly obtain the bulk density of soil, Young’s modulus, bulk modulus, shear modulus and allowable bearing capacity from the compressional wave velocities. The results obtained correlated with the results of standard geotechnical investigations carried out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characterize" title="characterize">characterize</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=geophysical" title=" geophysical"> geophysical</a>, <a href="https://publications.waset.org/abstracts/search?q=geotechnical" title=" geotechnical"> geotechnical</a>, <a href="https://publications.waset.org/abstracts/search?q=regression" title=" regression"> regression</a> </p> <a href="https://publications.waset.org/abstracts/37069/analysis-of-geotechnical-parameters-from-geophysical-information" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37069.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">370</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">25</span> Progress, Challenges, and Prospects of Non-Conventional Feed Resources for Livestock Production in Sub-Saharan Africa: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clyde%20Haruzivi">Clyde Haruzivi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20Oyebade%20Ikusika"> Olusegun Oyebade Ikusika</a>, <a href="https://publications.waset.org/abstracts/search?q=Thando%20Conference%20Mpendulo"> Thando Conference Mpendulo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Feed scarcity, increasing demand for animal products due to the growing human population, competition for conventional feed resources for humans and animal production, and ever-increasing prices of these feed resources are major constraints to the livestock industry in Sub-Saharan Africa. As a result, the industry is suffering immensely as the cost of production is high, hence the reduced returns. Most affected are the communal and resource-limited farmers who cannot afford the cost of conventional feed resources to supplement feeds, especially in arid and semi-arid areas where the available feed resources are not adequate for maintenance and production. This has tasked researchers and animal scientists to focus on the potential of non-conventional feed resources (NCFRs). Non-conventional feed resources could fill the gap through reduced competition, cost of feed, increased supply, increased profits, and independency as farmers will be utilizing locally available feed resources. Identifying available non-conventional feed resources is vital as it creates possibilities for novel feed industries and markets and implements methods of using these feedstuffs to improve livestock production and livelihoods in Sub-Saharan Africa. Hence, this research work analyses the progress, challenges, and prospects of some non-conventional feed resources in Sub-Saharan Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-conventional" title="non-conventional">non-conventional</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20resources" title=" feed resources"> feed resources</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock%20production" title=" livestock production"> livestock production</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=Sub-Saharan" title=" Sub-Saharan"> Sub-Saharan</a> </p> <a href="https://publications.waset.org/abstracts/156542/progress-challenges-and-prospects-of-non-conventional-feed-resources-for-livestock-production-in-sub-saharan-africa-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156542.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">113</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Comparative Analysis of Various Waste Oils for Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20Ayodeji%20Olagunju">Olusegun Ayodeji Olagunju</a>, <a href="https://publications.waset.org/abstracts/search?q=Christine%20Tyreesa%20Pillay"> Christine Tyreesa Pillay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biodiesel from waste sources is regarded as an economical and most viable fuel alternative to depleting fossil fuels. In this work, biodiesel was produced from three different sources of waste cooking oil; from cafeterias, which is vegetable-based using the transesterification method. The free fatty acids (% FFA) of the feedstocks were conducted successfully through the titration method. The results for sources 1, 2, and 3 were 0.86 %, 0.54 % and 0.20 %, respectively. The three variables considered in this process were temperature, reaction time, and catalyst concentration within the following range: 50 oC – 70 oC, 30 min – 90 min, and 0.5 % – 1.5 % catalyst. Produced biodiesel was characterized using ASTM standard methods for biodiesel property testing to determine the fuel properties, including kinematic viscosity, specific gravity, flash point, pour point, cloud point, and acid number. The results obtained indicate that the biodiesel yield from source 3 was greater than the other sources. All produced biodiesel fuel properties are within the standard biodiesel fuel specifications ASTM D6751. The optimum yield of biodiesel was obtained at 98.76%, 96.4%, and 94.53% from source 3, source 2, and source 1, respectively at optimum operating variables of 65 oC temperature, 90 minutes reaction time, and 0.5 wt% potassium hydroxide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20cooking%20oil" title="waste cooking oil">waste cooking oil</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acid%20content" title=" free fatty acid content"> free fatty acid content</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium%20hydroxide%20catalyst" title=" potassium hydroxide catalyst"> potassium hydroxide catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20analysis" title=" optimization analysis"> optimization analysis</a> </p> <a href="https://publications.waset.org/abstracts/173330/comparative-analysis-of-various-waste-oils-for-biodiesel-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173330.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Geochemical Evaluation of Weathering-Induced Release of Trace Metals from the Maastritchian Shales in Parts of Bida an Anambra Basins, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adetunji%20Olusegun%20Aderigibigbe">Adetunji Olusegun Aderigibigbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shales, especially black shales, are of great geological significance, in the study of heavy/trace metal contamination. This is due to their abundance in occurrence and high concentration of heavy metals embedded which are released during their weathering. Heavy metals constitute one of the most dangerous pollution known to human because they are toxic (i.e., carcinogenic), non-biodegradable and can enter the global eco-biological circle. In the past, heavy metal contamination in aquatic environment and agricultural top soil has been attributed to industrial wastes, mining extractions and pollution from traffic vehicles; only a few studies have focused on weathering of shale as possible source of heavy metal contamination. Based on the above background, this study attempts to establish weathering of shale as possible source of trace/heavy metal contaminations. This was done by carefully selecting fresh and their corresponding weathered shale samples from selected localities in Bida and Anambra Basins. The samples were analysed in Activation Laboratories Ltd; Ontario, Canada for trace/heavy metal. It was observed that some major and trace metals were released during weathering, i.e., some were depleted and some enriched. By this contamination of water zones and agricultural top soils are not only traceable to biogenic processes but geogenic inputs (weathering of shale) as well. <p
