Preface

This year the 8th WSEAS International Conference on E-ACTIVITIES (E-ACTIVITIES '09) and the 8th WSEAS International Conference on INFORMATION SECURITY and PRIVACY (ISP '09) were held at Puerto De La Cruz, Tenerife, Canary Islands, Spain, December 14-16, 2009. The conferences remain faithful to their original idea of providing a platform to discuss e- learning, e-communities, e-commerce, e-management, e-marketing, e-governance, tele-working, threat and attacks to information, modeling and analysis for information security, standards of information security, infrastructure for information security, tools for information security, applications of information security, cryptography, advanced topics in security, multilateral security etc. with participants from all over the world, both from academia and from industry.

Their success is reflected in the papers received, with participants coming from several countries, allowing a real multinational multicultural exchange of experiences and ideas.

The accepted papers of these conferences are published in this Book that will be indexed by ISI.

Please, check it: www.worldses.org/indexes as well as in the CD-ROM Proceedings. They will be also available in the E-Library of the WSEAS. The best papers will be also promoted in many Journals for further evaluation.

Conferences such as these can only succeed as a team effort, so the Editors want to thank the International Scientific Committee and the Reviewers for their excellent work in reviewing the papers as well as their invaluable input and advice.

Plenary Lecture 1

Performance Measurement and Management: State of Art and Future Agenda

Dr. Paolo Taticchi

Department of Industrial Engineering University of Perugia

Via G. Duranti, 06125 Perugia Italy

E-mail: paolo.taticchi@unipg.it

Abstract: In recent years, performance measurement and management (PMM) has received much attention from researchers and practitioners. Despite the growing use of PMM systems, companies experience difficulty in implementing such systems, with consequent risk of partial benefits or total goal failure. The literature on PMM is quite vast, but only few of the models address the problem in its entirety, while many other works focus on specific issues related to PMM. The purpose of this plenary speech is to analyze the state of the art of PMM models for small and medium enterprises (SMEs) and large companies. The evolution of the literature on PMM models and frameworks is highlighted starting from the development of the last twenty years. The methodology adopted for reviewing the literature relies on the citation/co-citation analysis of research on PMM and on the analysis of the frameworks/models developed in the last twenty years both for large and SMEs. The evolution of the research field is discussed and future areas of research are identified. During this talk, the role of PMM in respect of Business Intelligence (BI) tools will be also discussed.

Brief Biography of the Speaker:

Paolo Taticchi is Assistant Professor in Management Engineering at Perugia University, Italy, where he also serves as Lecturer in Economics and Management.

Moreover, he is curently visiting scholar at Stern Business School, NYU, New York. His research activities focus in the fields of: performance measurement and management, business networks and operations sustainability.

He is author and co-author of numerous research papers published in referred journals and conference proceedings, and he has been author and editor of national and international books. such us "Business Performance Measurement and Management: New contexts, themes and challenges" published by Springer.

He teaches undergraduate and graduate courses, as well as MBA and E-MBA internationally.

Finally, he served as Director of the 1st International Summer School "Piero Lunghi" organized by Perugia University, on "Perspectives of Business Performance Management", PACE University, New York, 2009.

Plenary Lecture 2

Facial Identification as non Invasive System

E-mail: ctravieso@dsc.ulpgc.es

Abstract: The face identification is a non invasive method, representing a great advantage against other biometric systems, which request the user’s collaboration. Two types of methods were proposed to extract face features for expression recognition, namely the image-based and the model-based methods. They differ in the way to process the images.

Model-based methods are a popular way to extract features. This type of systems is quite hard to work with, due to the fact that people constantly change their expression, even with just speaking. In fact, the typical limitations for this type of systems are that the face should be inside a certain margin of rotation (smaller than 15 degrees), and that the expression should not change so much. Model-based methods should only be applied when the subject cooperates for the recognition. Inside this type of study, a great variety of references can be found. Image-based methods are an alternative to extract facial expression features. They create a transformation, to pass from the spatial domain (image) to another transformed domain. This modality allows to research with a greater margin of variation on the faces, since for this method it is not necessary to have some characteristic points. The advantage of this type of techniques is that it is able to distinguish persons regardless of wearing eyeglasses or light beard, and even permits a greater degree of rotation of the head in all directions.

Brief Biography of the Speaker:

Dr. Carlos M. Travieso-Gonzalez was born in Spain in 1971. He received the M.Sc. degree in 1997 in Telecommunication Engineering at Polytechnic University of Catalonia (UPC), Spain. Besides, he received Ph.D.

degree in 2002 at University of Las Palmas de Gran Canaria (ULPGC-Spain). He is an Associate Professor from 2001 in ULPGC, teaching subjects on signal processing and learning theory. His research lines are biometric systems, classification system, medical signal processing, environmental intelligence, and data mining. He has researched in 22 International and Spanish Research Projects, some of them as head researcher. He has 140 papers published in international journals and conferences. He has been reviewer in different international journals and conferences since 2001. He is Image Processing Technical IASTED Committee Member. He is Vice-Dean from 2004 in Higher Technical School of Telecommunication Engineers in ULPGC.
