Abstract

Geopolymer Concrete (GPCs) is a new class of concrete based on an inorganic alumino-silicate binder system compared to the hydrated calcium silicate binder system of concrete. It possesses the advantages of rapid strength gain, elimination of water curing, good mechanical and durability properties and is eco-friendly and sustainable alternative to Ordinary Portland cement (OPC) based concrete. In the construction industry mainly the production of Portland cement causes the emission of air pollutants which results in environmental pollution. Geopolymer concrete are non Portland cement based binders with alkaline activation of industrial wastes such as fly ash and GGBS (Ground Granulated Blast furnace Slag), Sand and Coarse aggregates.............

Keywords: Ground Granulated Blast furnace Slag, Fly Ash, Alkaline Liquids, Sand, Coarse aggregate, Compressive Strength, Split Tensile Strength.

Abstract

Cholera continues to emerge in Far North Region of Cameroon and remains an important health challenge. In this work, dynamical system of mathematical model obtained from existing techniques of modelling was studied. The various numerical values obtained such as eigenvalues and basic reproduction number determine the stability of equilibrium points. Cholera epidemiological data given by the Regional Delegation of Health of Far North Region (Cameroon) allowed us to obtain the results using MATLAB software to implement the discretisation of the RungeKutta 4 (RK4) method. The numerical simulations lead us to predict the dynamics of population in the various compartments of the SIR-B cholera transmission model........

Keywords: Cholera, Vibrio cholera, Epidemiology, Dynamical, Modeling, Stability, Basic Reproduction Number.

Abstract

Cloud Computing is the new IT term that makes the availability of computing resources (Hardware and Software), applications and data as a service over the internet to its clients. Cloud computing largely expected to offer consistent, vibrant and virtualized services in terms of resources for doing computation, storage, and data sharing. An important requirement in cloud computing is scheduling of jobs to be accomplished within some given metrics or limits. In Cloud computing, finishing of tasks requires various resources which are available to them by filling certain constraints like best performance, minimum execution time, shortest response time, fault-tolerance and quality of expected services. The scheduler should command the jobs in a way where the steadiness between refining the quality of services and at the same time protecting the effectiveness and fairness of the jobs. Thus, in large-scale dispersed systems, the performance assessment of the algorithm is important. Here, our main objective is to learn various job scheduling algorithms.
