Character Recognition - Original PDF
نویسندگان: خلاصه: . Introduction The advancements in pattern recognition has accelerated recently due to the many emerging applications which are not only challenging, but also computationally more demanding, such evident in Optical Character Recognition (OCR), Document Classification, Computer Vision, Data Mining, Shape Recognition, and Biometric Authentication, for instance. The area of OCR is becoming an integral part of document scanners, and is used in many applications such as postal processing, script recognition, banking, security (i.e. passport authentication) and language identification. The research in this area has been ongoing for over half a century and the outcomes have been astounding with successful recognition rates for printed characters exceeding 99%, with significant improvements in performance for handwritten cursive character recognition where recognition rates have exceeded the 90% mark. Nowadays, many organizations are depending on OCR systems to eliminate the human interactions for better performance and efficiency.

Consensus Over Switching Network Topology: Characterizing System Parameters and Joint Connectivity - Original PDF
نویسندگان: خلاصه: This book aims to extend existing works on consensus of multi-agent systems systematically. The agents to be considered range from double integrators to generic linear systems. The primary goal is to explicitly characterize how agent parameters, which reflect both self-dynamics and inner coupling of each agent, and switching network topologies jointly influence the collective behaviors. A series of necessary and/or sufficient conditions for exponential consensus are derived. The contents of this book are as follows. Chapter 1 provides the background and briefly reviews the advances of consensus of multi-agent systems. Chapter 2 addresses the consensus problem of double integrators over directed switching network topologies. It is proven that exponential consensus can be secured under very mild conditions incorporating the damping gain and network topology. Chapter 3 considers generic linear systems with undirected switching network topologies. Necessary and sufficient conditions on agent parameters and connectivity of the communication graph for exponential consensus are provided. Chapter 4 furthers the study of consensus for multiple generic linear systems by considering directed switching network topologies. How agent parameters and joint connectivity work together for reaching consensus is characterized from an algebraic and geometric view. Chapter 5 extends the design and analysis methodology to containment control problem, where there exist multiple leaders. A novel analysis framework from the perspective of state transition matrix is developed. This framework relates containment to consensus and overcomes the difficulty of construction of a containment error. This book serves as a reference to the main research issues and results on consensus of multi-agent systems. Some prerequisites for reading this book include linear system theory, matrix theory, mathematics, and so on.
Cultural Resources for Tourism: Patterns, Processes and Policies - Original PDF
نویسندگان: خلاصه: The cultural heritage of regions and communities is presently being rediscovered and valorised as a driving force in building cultural identity and as a ubiquitous resource for dynamizing cultural activities. This process can lead to the development of cultural capital with clear territorial links and, as such, a favourable incubation condition for creating sustainable and competitive forms of cultural tourism. Research on cultural resources for tourism implies both a multidisciplinary approach and methodological innovations to deal with such a complex phenomenon. The challenge to identify and map cultural heritage elements - tangible and intangible - in a pan European context has recently been dealt with in the ESPON project 1.3.3 (2004-2006). Lack of adequate definitions, poor databases, and a showcase of national and sector differences in approaching culture as 'resource' for development was the final balance of that explorative project. These findings have prompted further case study research into the study of cultural heritage, which is encapsulated in this book. This publication differs from others on cultural tourism through its emphasis on spatial dynamics, by analyzing location and behavior patterns in different tourism destinations, by identifying the parameters of change induced by tourism and, not in the least, trial and error examples in policy making. The book includes a rich variety of case studies mainly from all over Europe (but also including cases set in Israel, Cairo and India), representing the views and findings of 21 international researchers and scholars in cultural tourism, scanning unique situations in order to detect the common dynamics and impacts of tourismification. The final objective is to propose consistent directions for policy, based on empirical insights. The book contributes significantly to the understanding of cultural diversity and territorial identity, on the one hand, and to the dynamics of tourism, on the other, all of which are key issues in local and regional planning and management. As such, they should be a source of inspiration for policy-makers and an eye-opener for students, researchers and consultants in the field of cultural heritage and tourism and, hopefully, an interesting virtual trip - from Savonlinna to Cairo, from Santiago de Compostela to Sibiu - crossing and discovering a kaleidoscope of colourful and unique cultural landscapes and tourismscapes.
