This book discusses current topics in rough set theory. Since Pawlak’s rough set theory was first proposed to offer a basis for imprecise and uncertain data and reasoning from data, many workers have investigated its foundations and applications. Examining various topical issues, including object-oriented rough set models, recommendation systems, decision tables, and granular computing, the book is a valuable resource for students and researchers in the field.

With many updates and additional exercises, the second edition of this book continues to provide readers with a gentle introduction to rough path analysis and regularity structures, theories that have yielded many new insights into the analysis of stochastic differential equations, and, most recently, stochastic partial differential equations.

This book is dedicated to the memory of Professor Zdzis{\l}aw Pawlak who passed away almost six year ago. He is the founder of the Polish school of Artificial Intelligence and one of the pioneers in Computer Engineering and Computer Science with worldwide influence. He was a truly great scientist, researcher, teacher and a human being.

What is it about the desolate far North American wilderness that calls the intrepid traveler to uncover its sanctifying and deadly secrets? From Jack London (Call of the Wild) to Christopher McCandless (chronicled in Jon Krakauer's Into the Wild) souls have found solace in the silent, frozen northern kingdom at the top of the world, the Ultima Thule. The forested flatlands give way to the frozen Rocky Mountains over millions of acres nominally in the dominion of both the United States and Canada and accessible by its 1532 mile shared umbilical cord—The Alcan Highway. Legendary vagabond, Jim Christy, a Canadian now but born an American travels this road throughout his life.

During the past few years, data mining has grown rapidly in visibility and importance within information processing and decision analysis. This is par­ ticularly true in the realm of e-commerce, where data mining is moving from a "nice-to-have" to a "must-have" status. In a different though related context, a new computing methodology called granular computing is emerging as a powerful tool for the conception, analysis and design of information/intelligent systems. In essence, data mining deals with summarization of information which is resident in large data sets, while granular computing plays a key role in the summarization process by draw­ ing together points (objects) which are related through similarity, proximity or functionality. In this perspective, granular computing has a position of centrality in data mining. Another methodology which has high relevance to data mining and plays a central role in this volume is that of rough set theory. Basically, rough set theory may be viewed as a branch of granular computing. However, its applications to data mining have predated that of granular computing.

In this book, the authors present a comprehensive study of the effects of operating parameters (load, amplitude, frequency) on dry gross fretting of rough surfaces. It helps the reader to efficient surface preparations in order to monitor and reduce damage caused by fretting. It exposes the effect of surface topography on fretting, which is often neglected.

This book elucidates heat transfer behavior for boiling of dilute emulsions- mixtures of two immiscible fluids- which has received little attention to date. Of the work completed in this area, the majority has been focused on pool boiling where no mean flow is present, and this book is the first major work to be published regarding flow boiling of emulsions. The book includes a comprehensive review and assessment of research on emulsion-based heat transfer. Recent experiments are reported and analyzed to characterize heat transfer in microgap flow boiling via a systematic investigation into the effects of gap size, mass flux, and volume fraction on the heat transfer coefficient and pressure drop.
