Earned Value Management (EVM) is the most recognized tool for monitoring and controlling project performance. Its ultimate goal is to provide reliable early warning signals about the cost and schedule performance of a project. However, EVM has its limitations in monitoring and controlling software project activities. The lack of quality performance indicator and the inadequacy in incorporating the...
The rapid proliferation of computing processing power has facilitated a rise in the adoption of computers in various aspects of human lives. From education to shopping and other everyday activities to critical applications in finance, banking and, recently, degree awarding online education.

The effects of highly reactive aggregate, fused silica, and slowly reactive aggregate, Thames Valley sand, on the mechanical properties of concrete were investigated in this paper. The mechanical properties studied over a period of 12 months were the compressive strength, direct tensile strength, tensile splitting strength, flexural tensile strength (modulus of rupture), static modulus of elasticity...
