This edited volume focuses on the adoption of run-time models for the design and management of autonomic systems. Traditionally, performance models have a central role in the design of computer systems. Models are used at design-time to support the capacity planning of the physical infrastructure and to analyze the effects and trade-offs of different architectural choices. Models may also be used at run-time to assess the compliance of the running system with respect to design-time models, to measure the real system performance parameters to fill the gap between design and run-time. Models at run-time can also assess the compliance of service level agreements and trigger autonomic systems re-configuration. Run-time models are receiving great interest, since, e.g., power management of CPUs and resource management in virtualized systems can be actuated at very fine grain time scales. In such situations, traditional performance techniques evaluating the systems steady state may provide only a rough estimate of system behavior and are not effective to react to workload fluctuations. This book includes advanced techniques and solutions for the run-time estimation of autonomic systems performance, the analysis of transient conditions and their application in advanced prototype environments. |

GDI+ Custom Controls with Visual C# 2005The amount of built-in functionality included in the .NET Framework is amazing. One could create complex applications with lots of functionality by simply assembling the pieces you're offered for free. Among those pieces you'll find lots of powerful, flexible, and configurable controls. Who would ever need to build their own controls, right? ... | | Electrical Installation Work, Fifth EditionElectrical Installation Work covers both theory and practice for the trainee who wants to understand not only how, but why electrical installations are designed, installed and tested in particular ways. Brian Scaddan's approach encourages independent learning with self-assessment questions provided throughout.
