This paper presents figures to significantly gauge insecurity levels in Sub-Saharan Africa. A topic of growing debate globally is insecurity. And Sub-Saharan Africa has its fair share, ranging from the ebola virus disease (EVD), climate change vulnerability, environmental risk, food insecurity to terrorism. Insecurity has reputation for depleting socio-economic activities. The social contract between government and the governed makes it mandatory for any responsible and responsive government to avail its citizens socio-economic transformation. Researchers, practitioners and captains of industry have concurred that tackling insecurity requires a multi-prong approach spanning political, economic, technological and military solutions. Though the mechanics of insecurity may seem the same across climes, the same cannot be said of the ideology. Studies have shown that insecurity in Africa is hinged on poverty and ignorance. Using secondary data and modelling, this study applies Information and Communications Technologies (ICTs) in combating poverty and ignorance in Sub-Saharan Africa through e-Education, e-Health, e-Agriculture and e-Social Security. The research study provides empirical data for substantiating poverty-driven insecurity. It also outlines guidelines for designing and implementing ICTs policies, programmes and projects for sustained and sustainable development within the framework of Africa's economic status quo. The expectation is that these measures will engender social transformation and security. © The Authors, 2015. Source

By using the wave function ansatz method, we study the energy eigenvalues and wave function for any arbitrary m-state in two-dimensional Schrödinger wave equation with various power interaction potentials in constant magnetic and Aharonov-Bohm (AB) flux fields perpendicular to the plane where the interacting particles are confined. We calculate the energy levels of some diatomic molecules in the presence and absence of external magnetic and AB flux fields using different potential models. We found that the effect of the Aharonov-Bohm field is much as it creates a wider shift for m≠. 0 and its influence on m=. 0 states is found to be greater than that of the magnetic field. To show the accuracy of the present model, a comparison is made with those ones obtained in the absence of external fields. An extension to 3-dimensional quantum system have also been presented. © 2014 Elsevier Inc. Source

Within the framework of restricted four-body problem, we study the motion of an infinitesimal mass by assuming that the primaries of the system are radiating-oblate spheroids surrounded by a circular cluster of material points. In our model, we assume that the two masses of the primaries m2 and m3 are equal to μ and the mass m1 is 1−2μ. By using numerical approach, we have obtained the equilibrium points and examined their linear stability. The effect of potential created by the circular cluster and oblateness coefficients for the more massive primary and the less massive primary, on the existence and linear stability of the libration point have been critically examine via numerical computation. The stability of these points examined shows that the collinear and the non-collinear equilibrium points are unstable. The result presented in this paper have practical application in astrophysics. © 2014, Springer-Verlag Wien. Source

An important factor that needs to be considered by every Grid application end-user and systems (such as schedulers or mediators), during Grid resource selection and mapping to applications, is the performance capacity of hardware resources attached to the Grid, and made available through its Virtual Organizations. In this paper, we represent the performance of a computational Grid as a regression model that can be used to fine-tune the selection of suitable Grid resources. A study on the performance of distributed systems with respect to particular variations in parameters is presented. Our objective is to use a measurement-based evaluation technique to characterize the specific performance contribution of the individual Grid resource configurations. In the process, we identify the key primary parameters (or factors) that should be considered when selecting and allocating a computational node for user application execution. © 2016 - IOS Press and the authors.

We present a simple formula for finding bound state solution of any quantum wave equation which can be simplified to the form of (Formula Presented.). The two cases where k3 = 0 and (Formula Presented.) are studied. We derive an expression for the energy spectrum and the wave function in terms of generalized hypergeometric functions (Formula Presented.). In order to show the accuracy of this proposed formula, we resort to obtaining bound state solutions for some existing eigenvalue problems in a rather more simplified way. This method has shown to be accurate, efficient, reliable and very easy to use particularly when applied to vast number of quantum potential models. © 2014, Springer-Verlag Wien. Source
