What is knowledge and how is it represented? This book focuses on the idea of formalising knowledge as relations, interpreting knowledge represented in databases or logic programs as relational data and discovering new knowledge by identifying hidden and defining new relations. After a brief introduction to representational issues, the author develops a relational language for abstract machine learning problems. He then uses this language to discuss traditional methods such as clustering and decision tree induction, before moving onto two previously underestimated topics that are just coming to the fore: rough set data analysis and inductive logic programming. Its clear and precise presentation is ideal for undergraduate computer science students. The book will also interest those who study artificial intelligence or machine learning at the graduate level. Exercises are provided and each concept is introduced using the same example domain, making it easier to compare the individual properties of different approaches.

Liquid Surfaces and Interfaces: Synchrotron X-ray Methods

The availability of synchrotron x-ray sources and the subsequent developments described in this book have led to substantial progress in our understanding of molecular ordering at liquid interfaces. This practical guide enables graduate students and researchers working in physics, chemistry, biology and materials science to understand and carry out experimental investigations into the basic physical and chemical properties of liquid surfaces and interfaces. The book examines the surfaces of bulk liquids, thin wetting films and buried liquid-liquid interfaces. It discusses experiments on simple and complex fluids, including pure water and organic liquids, liquid crystals, liquid metals, electrified liquid-liquid interfaces and interfacial monolayers of amphiphiles, nanoparticles, polymers and biomolecules. A detailed description of the apparatus and techniques required for these experiments is provided, and theoretical approaches to data analysis are described, including approximate methods such as the Master formula, the Born approximation, Parratt's algorithm and the Distorted Wave Approximation.

On an everyday basis, we communicate with one another using various technological media, such as text messaging, social networking tools, and electronic mail, in work, educational, and personal settings. As a consequence of the increasing frequency of use and importance of computer-supported interaction, social scientists in particular have heeded the call to understand the social processes involved in such interactions. In this volume, the editors explore how aspects of a situation interact with characteristics of a person to help explain our technologically-supported social interactions. The person-by-situation interaction perspective recognizes the powerful role of the situation and social forces on behavior, thought, and emotion, but also acknowledges the importance of person variables in explaining social interaction, including power and gender, social influence, truth and deception, ostracism, and leadership. This important study is of great relevance to modern readers, who are more and more frequently using technology to communicate with one another.
