Abstract Cloud Computing is playing a huge role in future technology. Further, with the explosive growth of Internet and cloud computing, several service providers, such as Amazon, Microsoft, IBM, Google, have expanded their data centers rapidly deployed different places around world to deliver various computing services. However, challenges are raised wide spread use environment power consumpt...

In biped locomotion, the energy minimization problem is a challenging topic. This problem cannot be solved analytically since modeling the whole robot dynamics is intractable. Using the inverted pendulum model, researchers have defined the Zero Moment Point (ZMP) target trajectory and derived the corresponding Center of Mass (CoM) motion trajectory, which enables a robot to walk stably. A chang...

Cloud Computing has recently emerged as a highly successful alternative information technology paradigm through on-demand resource provisioning and almost perfect reliability. In order to meet the customer demands, Cloud providers are deploying large-scale virtualized data centers consisting of thousands of servers across the world. These data centers require huge amount of electrical energy th...

It is often suggested that if all sound change were due to optimizations of functional principles (minimization of articulatory effort, minimization of perceptual confusion), then sound systems should have increasingly improved during the course of history, probably to the point that they should by now have reached a stable optimum. Since the facts show, however, that sound systems tend never t...
