Abstract: Many models were presented to solve the static transmission network expansion planning (STNEP) problem by previous research. However, in these models, lines’ voltage level and losses were not studied in STNEP. Therefore, in present paper, static transmission expansion planning is investigated by considering lines’ voltage, losses and bundles using decimal codification genetic algorithm (DCGA). The DCGA is better than mathematical methodologies to solve large-scale, nonlinear and mixed-integer optimization problems, like the TNEP. The proposed method is tested on the real transmission network of Azarbaijan regional electric company, Iran. The results show that operation costs decreases considerably and the transmission system delivered more safe and reliable electric power to customers if the network losses, voltage levels and the number of bundle lines are considered in transmission expansion planning.

Abstract: The problems, challenges, and benefits of a Virtual Value Creation (VVC) environment and subsequent deployment of requisite infrastructure to cater for same, save the process of digitization, in an Information Communication Technology (ICT) responsive environment, are all connected to the evolving concept of cloud computing. The uniqueness of every organization affects the virtualization of its ICT and applications. However, provisioning the right cloud computing model to match the strategic and operational goals of such organization is an accepted solution. This paper is aimed at evolving an enhanced model that integrates cloud computing model (CCM) with the VVC Framework of Virtual Organization (VO) to assist the virtual organization stakeholders in reducing the huge capital investment, maintenance, technical personnel, etc. requirements often associated with essential ICT infrastructural setup needs, as well as relieve the top management of technical issues thereby enhancing their focus on core business issues while managing a Virtual organization. VO stakeholders could be afforded the opportunity in the resultant integrated model, the “Cloud Virtual Organization (CVO)”, to create better, optimal and customized values in terms of flexibility, cost savings, better scalability, reduced complexity in business processes, increased business focus, advanced technology, better functionality and improved security among others. It is submitted that the foregoing parameters enlisted as features offered by the CVO will immensely propel a Virtual organization towards earning global corporate visibility, competitive advantage, and socio-economic influence in the ever-changing global business environment.

Abstract: This paper presents simple approach to determine an Equivalent Solutions to some Integral Calculus Problems. An experimental study was carried out on one hundred and twenty (120) students offering Integral Calculus Course in the Department of Mathematics, Adeniran Ogunsanya College of Education, Otto/Ijanikin, Lagos State. The sample chosen includes male and female students from the following course combinations: Physics / Mathematics, Chemistry / Mathematics, Computer / Mathematics, Integrated Science / Mathematics, Economics / Mathematics, Biology/Mathematics and Geography / Mathematics. The students were grouped into seven based on their course combinations. The students in their respective groups were subjected to the same problem on integration where they are free to use any method of integration of their choice. The students came up with various solutions to a given integral calculus problem. Each of the solutions obtained in each group was evaluated on specified interval to determine the numerical value in order to draw inference on equivalent solutions. Maple software was used to determine if the solutions from each group are equivalent or differs. The numerical value and graphical representation of the solutions from each group using Maple software shows that the solutions obtained by the students in their respective groups are equivalent. Hence, maple software adaptation in teaching integral calculus enhanced the students’ learning and by extension shows that equivalent solutions to some problems on integral calculus exists.

Abstract: The Abraham-Minkowski controversy of light refracting to a system is a century-old milk and water at light refraction on a medium. The physicists are in long debate to pick and choose the Abraham or Minkowski forma at calculating momentum of light in a medium during reflection at dynamic environment in astrophysics. This study is designed to ride an anchor in view of mitigating these ongoing hot water in physical geospatialities. Results divulged Abraham-Minkowsky friendship on the equation (16) envelop can turn over a new leaf to the contrary of these Abraham-Minkowski controversy in light physics. Also, it can be a uniquely functional modeling to be used as ρ = ηE / c = E / ηc dancing in worldwide confusion over the controversry.
