Quantum theory is one of the most important intellectual developments in the early twentieth century. The confluence of mathematics and quantum physics emerged arguably from Von Neumann's seminal work on the spectral theory of linear operators. This volume arose from a two-month workshop held at the Institute for Mathematical Sciences at the National University of Singapore in JulySeptember 2008 on mathematical physics, focusing specifically on operator algebras in quantum theory.

This volume is essentially written for graduate students and young researchers so that they can acquire a gentle introduction to the application of operator algebras to quantum information sciences, chaotic and many-body problems. Several lecture notes delivered during the workshop by experts in the field were specially commissioned for this volume.

This book constitutes the thoroughly refereed proceedings of the first International Conference on Context-Aware Systems and Applications, ICCASA 2012, held in Ho Chi Minh City, Vietnam, in November 2012. The 34 revised full papers presented were carefully selected and reviewed from over 100 submissions. The papers cover a wide spectrum of issues in the area of Context-Aware Systems (CAS). CAS are going to shape networked computing systems of the future

Welcome to ICSOC-ServiceWave 2009. This volume contains the research and demopapersselectedforpresentationattheSeventhInternationalConferenceon Service-Oriented Computing, which was held in Stockholm, Sweden, November 24-27, 2009. Continuing the tradition set in the previous six years, we are pleased to present a high-quality technical program.This year ICSOC ServiceWaveworked together to convey a world-leading and unique opportunity for academic - searchers and industry practitioners to report their state-of-the-art research ?ndings in service-orientedcomputing. The joint conference aims to foster cro- community scienti?c excellence by gathering experts from various disciplines such as distributed systems, software engineering, computer networks, business intelligence, service science, grid and cloud computing, and security. Consistent with the high quality of the conference, we received 228 paper submissions from a number of di?erent disciplines. Thirty-sevenpapers were - cepted as regular contributions, for a very competitive acceptance rate of 16%; eight further submissions were accepted as short papers.
