The authors develop a system of differential equations describing the motion of the structural system equipped with DFP bearings. The Runge-Kutta numerical method, specifically the ode15s function in MATLAB, was used to solve these equations. The results of the calculations provide a comparison of the damping efficiency of the structural system with and without the use of DFP bearings, assessing the effectiveness of vibration isolation during an earthquake, with three components X, Y, and vertical considered.

The need for operating circuits at increasingly higher speeds has always challenged designers. From radar and television systems in the 1940s to gigahertz microprocessors today, the demand for pushing circuits to higher frequencies has required a solid understanding of their speed limitations. In this chapter, we study the effects that limit the speed of transistors and circuits, identifying topologies that better lend themselves to high-frequency operation.

Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

This work demonstrated the potential of US for mitigating membrane fouling. However, the integration of the US transducers within the membrane system will be a major challenge for the application of US in membrane cleaning. It is more appropriate that US is used as pre-treatment to the membrane system, the transducers can be placed prior to the coagulant feed line. Further work on the determination of the detailed mechanisms associated with enhancing coagulation would enable optimisation of the system with regard to process, cost and energy efficiency.
