The field of Intelligent Systems and Applications has expanded enormously during the last two decades. Theoretical and practical results in this area are growing rapidly due to many successful applications and new theories derived from many diverse problems. This book is dedicated to the Intelligent Systems and Applications in many different aspects. In particular, this book is to provide highlights of the current research in Intelligent Systems and Applications. It consists of research papers in the following specific topics: l Graph Theory and Algorithms l Interconnection Networks and Combinatorial Algorithms l Artificial Intelligence and Fuzzy Systems l Database, Data Mining, and Information Retrieval l Information Literacy, e-Learning, and Social Media l Computer Networks and Web Service/Technologies l Wireless Sensor Networks l Wireless Network Protocols l Wireless Data Processing This book provides a reference to theoretical problems as well as practical solutions and applications for the state-of-the-art results in Intelligent Systems and Applications on the aforementioned topics. In particular, both the academic community (graduate students, post-doctors and faculties) in Electrical Engineering, Computer Science, and Applied Mathematics; and the industrial community (engineers, engineering managers, programmers, research lab staffs and managers, security managers) will find this book interesting.

This book constitutes the proceedings of the Second International Conference on Security-Enriched Urban Computing and Smart Grid, held in Hualien, Taiwan, in September 2011. The 35 revised full papers presented together with two invited papers were carefully reviewed and selected from 97 submissions. Among the topics covered are the internet of things, mobile networks, wireless networks, service-oriented computing, data-centric computing, voice over IP, cloud computing, privacy, smart grid systems, distributed systems, agent-based systems, assistive technology, social networks, and wearable computing.

Grid and Pervasive Computing (GPC) is an annual international conference on the emerging areas of grid computing and pervasive computing, aimed at p- viding an exciting platform and paradigm for all-the-time, everywhere services. GPC 2010 provided a high-pro?le, leading-edgeforum for researchersand dev- opers from industry and academia to present their latest research in the ?eld of grid and pervasive computing. Three workshops were held in conjunction with the GPC 2010 conference: * The First International Workshop on Intelligent Management of Networked Environment (IMNE 2010) * International Workshop on Multimedia Applications for Cloud (MAC 2010) * The 6thInternationalWorkshopon Mobile Commerce andServices (WMCS 2010) The proceedingsof these workshoparealso included in this volume. We received 184 papers originating from 22 countries. The Program Committee ?nally - lected 67 papers for presentation at the conference and inclusion in this LNCS volume. At GPC 2010, we were very pleased to have four distinguished invited speakers, who delivered state-of-the-art information on the conference topics: * A grid based virtual laboratory for HIV drugranking by Peter Sloot (U- versity of Amsterdam, The Netherlands) * Solving the scalability dilemma with clouds, crowds, and algorithms by Michael J. Franklin (University of California, Berkeley, USA) * The trend of cloud computing - from industry's perspective by Enwei Xie (Microsoft Greater China Region, China) * Towards ubiquitous a?ective learning by Bin Hu (The Birmingham City University, UK) Theconferencewouldnothavebeenpossiblewithoutthesupportofmanypeople andorganizationsthathelped invariouswaysto makeita success.

Security-enriched urban computing and smart grids are areas that attracted many a- demic and industry professionals to research and develop. The goal of this conference was to bring together researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to the multifaceted aspects of urban computing and the smart grid. This conference includes the following special sessions: Signal Processing, Image Processing, Pattern Recognition and Communications (SIPC 2010), Networking, Fault-tolerance and Security For Distributed Computing Systems (NFSDCS 2010), Security Technology Application (STA 2010), Electric Transportation (ElecTrans 2010), Techniques of Bi-directional Power Computing in High Voltage Power Supply (TBPC 2010), Low Power IT and Applications (LPITA 2010), Computational Intel- gence and Soft Computing (CISC 2010), Distributed Computing and Sensor Networks (DCSN 2010), Advanced Fusion IT (AFIT 2010), Social Media and Social Netwo- ing (SMSN 2010), Software Engineering and Medical Information Engineering (SEMIE 2010), Human-Centered Advanced Research/Education (HuCARE 2010), Database Integrity and Security (DIS 2010), Ubiquitous IT Application (UITA 2010) and Smart Grid Applications (SGA 2010). We would like to express our gratitude to all of the authors of the submitted papers and to all attendees, for their contributions and participation. We believe in the need for continuing this undertaking in the future.
