  • Some people raised their eyebrows when I told them that I was writing a book on congestion control, and said, ‘Is this topic really large enough for a book?’ Well, it certainly is, and I am sure that it is needed. For example, there are quite a number of Ph.D. students out there who work in this field–yet, when they start out, they do not have a comprehensive introductory book about the subject. This book is for them and, of course, for anyone else with an interest in this fascinating topic–graduate students, teachers in academia and network administrators alike...

  • Evolution of global technologies has prompted increasing complexity of applications developed in both, the industry and the scientific research fields. These complexities are generally attributed to nonlinearities, poorly defined dynamics and absence of apriori information about the systems. Imprecision, uncertainties and vagueness in information about the system are also playing vital roles in enhancing the complexity of application.

  • Worldwide, crude oil demand is unceasingly increasing. As a response, Enhanced Oil Recovery (EOR) processes have re‐gained interest from the research and development phases to the oilfield EOR implementation stage. This renewed interest has been also furthered by the current high oil price environment, the maturation of oilfields worldwide, and few new‐well discoveries. Concurrently, environmental concerns and public pressure related to crude oil pollution control and remediation of oilcontaminated sites are becoming greater than ever....

  • How Direct Expansion Air-Conditioning Achieves Performance Goals For most of the A / C market, refrigeration-based ( DX ) cooling is the standard, and provides a point of comparison for new technologies. To describe the benefits and improvements of DEVap A / C technology, we must discuss standard A / C. Standard A / C reacts to SHR by cooling the air sensibly and, if dehumidification is required, by cooling the air below the dew point.

  • Soil loss for erosion is a natural phenomenon in soil dynamics, influenced by climate, soil intrinsic properties, and morphology, that can both trigger and enhance the process. Anthropic activities, like inappropriate agricultural practices, deforestation, overgrazing, forest fires and construction activities, may exert a remarkable impact on erosion processes or, on the other hand, contribute to soil erosion mitigation through a sustainable management of natural resources.

  • Increased miniaturization of the integrated chip has largely been responsible for the rapid advances in semiconductor device performance, driving the industry’s growth over the past decade(s). Soon the minimum feature size in a typical integrated circuit device will be well below 100 nm. At these dimensions, interlayers with extremely low dielectric constants (k) are imperative to reduce the cross-talk between adjacent lines and also enhance device speed. State-of-the-art non-porous, silicon-based low-k dielectric materials have k values on the order of 2.7....
