QoS for Fixed and Mobile Ultra-Broadband (Wiley - IEEE)
by Toni JanevskiProvides extensive coverage of standardized QoS technologies for fixed and mobile ultra-broadband networks and services—bringing together technical, regulation, and business aspects The Quality of Service (QoS) has been mandatory for traditional telecommunication services such as telephony (voice) and television (TV) since the first half of the past century, however, with the convergence of telecommunication networks and services onto Internet technologies, the QoS provision remains a big challenge for all ICT services, not only for traditional ones. This book covers the standardized QoS technologies for fixed and mobile ultra-broadband networks and services, including the business aspects and QoS regulation framework, which all will have high impact on the ICTs in the current and the following decade. QoS for Fixed and Mobile Ultra-Broadband starts by introducing readers to the telecommunications field and the technology, and the many aspects of both QoS and QoE (Quality of Experience). The next chapter devotes itself to Internet QoS, starting with an overview of numerous technology protocols and finishing with business and regulatory aspects. The next three chapters look at QoS in NGN and Future Networks, QoS for fixed ultra-broadband, and QoS for mobile ultra-broadband. The book also provides readers with in-depth accounts of services in fixed and mobile ultra-broadband; broadband QoS parameters, KPIs, and measurements; network neutrality; and the QoS regulatory framework. Comprehensively covers every aspect of QoS technology for fixed and mobile ultra-broadband networks and services, including the technology, the many regulations, and their applications in business Explains how the QoS is transiting from the traditional telecom world to an all-IP world Presents all the fundamentals of QoS regulation, as well as SLA regulation QoS for Fixed and Mobile Ultra-Broadband is an excellent resource for managers, engineers, and employees from regulators, ICT government organizations, telecommunication companies (operators, service providers), ICT companies, and industry. It is also a good book for students and professors from academia who are interested in understanding, implementation, and regulation of QoS for fixed and mobile ultra-broadband.
QoS-Aware Virtual Network Embedding
by Chunxiao Jiang Peiying ZhangAs an important future network architecture, virtual network architecture has received extensive attention. Virtual network embedding (VNE) is one of the core services of network virtualization (NV). It provides solutions for various network applications from the perspective of virtual network resource allocation. The Internet aims to provide global users with comprehensive coverage. The network function requests of hundreds of millions of end users have brought great pressure to the underlying network architecture. VNE algorithm can provide effective support for the reasonable and efficient allocation of network resources, so as to alleviate the pressure off the Internet. At present, a distinctive feature of the Internet environment is that the quality of service (QoS) requirements of users are differentiated. Different regions, different times, and different users have different network function requirements. Therefore, network resources need to be reasonably allocated according to users' QoS requirements to avoid the waste of network resources. In this book, based on the analysis of the principle of VNE algorithm, we provide a VNE scheme for users with differentiated QoS requirements. We summarize the common user requirements into four categories: security awareness, service awareness, energy awareness, and load balance, and then introduce the specific implementation methods of various differentiated QoS algorithms. This book provides a variety of VNE solutions, including VNE algorithms for single physical domain, VNE algorithms for across multiple physical domains, VNE algorithms based on heuristic method, and VNE algorithms based on machine learning method.
Quad Rotorcraft Control
by Rogelio Lozano Claude Pégard Luis Rodolfo García Carrillo Alejandro Enrique Dzul LópezQuad Rotorcraft Control develops original control methods for the navigation and hovering flight of an autonomous mini-quad-rotor robotic helicopter. These methods use an imaging system and a combination of inertial and altitude sensors to localize and guide the movement of the unmanned aerial vehicle relative to its immediate environment. The history, classification and applications of UAVs are introduced, followed by a description of modelling techniques for quad-rotors and the experimental platform itself. A control strategy for the improvement of attitude stabilization in quad-rotors is then proposed and tested in real-time experiments. The strategy, based on the use low-cost components and with experimentally-established robustness, avoids drift in the UAV's angular position by the addition of an internal control loop to each electronic speed controller ensuring that, during hovering flight, all four motors turn at almost the same speed. The quad-rotor's Euler angles being very close to the origin, other sensors like GPS or image-sensing equipment can be incorporated to perform autonomous positioning or trajectory-tracking tasks. Two vision-based strategies, each designed to deal with a specific kind of mission, are introduced and separately tested. The first stabilizes the quad-rotor over a landing pad on the ground; it extracts the 3-dimensional position using homography estimation and derives translational velocity by optical flow calculation. The second combines colour-extraction and line-detection algorithms to control the quad-rotor's 3-dimensional position and achieves forward velocity regulation during a road-following task. In order to estimate the translational-dynamical characteristics of the quad-rotor (relative position and translational velocity) as they evolve within a building or other unstructured, GPS-deprived environment, imaging, inertial and altitude sensors are combined in a state observer. The text give the reader a current view of the problems encountered in UAV control, specifically those relating to quad-rotor flying machines and it will interest researchers and graduate students working in that field. The vision-based control strategies presented help the reader to a better understanding of how an imaging system can be used to obtain the information required for performance of the hovering and navigation tasks ubiquitous in rotored UAV operation.

Quality Assurance and Accreditation in Distance Education and e-Learning: Models, Policies and Research (Open and Flexible Learning Series)
by Insung Jung Colin LatchemQuality assurance (QA) in open and distance learning (ODL) can be a contentious issue. Some argue that it should be judged by the same criteria and methods as face-to-face education, while others claim that it is so different in its organization, enrolments and operations that conventional QA mechanisms cannot apply. Some advocate the use of specific guidelines and standards for e-learning; others believe that, regardless of the technology, the basic principles of quality teaching and learning should apply. Providers who have enjoyed freedom from external scrutiny may resist attempts at external regulation and auditing and look upon QA as yet another imposition of corporatization and bureaucracy on education. Others see it as a means of establishing a culture of quality, self-reflection and self-improvement. There is little research-based literature to guide policy-makers, managers and practitioners in applying QA in education and training to ensure the right balance is found between accountability and autonomy, as well as assuring quality for the time and costs involved. In this respect, Quality Assurance and Accreditation in Distance Education and e-Learning is a book that is long overdue. It explains what is involved in QA and accreditation in education. It describes and analyzes applications of these practices in open, distance, dual-mode and conventional universities throughout Europe, North America, Africa, and the Asia-Pacific, looking at open schooling, e-learning in conventional schools, non-formal adult and community education, and corporate and small-to-medium enterprises. Quality Assurance and Accreditation in Distance Education and e-Learning is edited and authored by experts with extensive international experience in ODL, e-learning and QA who give careful consideration to the possibilities and challenges involved. The book will be an invaluable guide for all policy-makers, managers, practitioners and researchers in the field.
Quality Assurance and the Law
by Richard Reeves Elaine PritchardOver the last 25 years there has been a considerable increase in the awareness of quality related issues. In the world of business and commerce, this awareness has manifested itself in the development of what was the British Quality Standard BS 5750 into what is now the international standard BS EN ISO 9000. Alongside all of this, consumers in general have developed increasingly demanding expectations with regard to the quality of goods and services available in the market place. During a similar period there has also been an increase in legislation, together with an expansion of the common law, which has strengthened the protection already afforded to the consumer. This book will provide quality practitioners, managers and those with a general interest in quality, with an insight into the legal issues involved. In addition, the book shows how the implementation of a Quality Assurance Management System - such as that required in order to be registered as a firm of assessed capability, in accordance with BS EN ISO 9000 - can act as an aid to businesses seeking to comply with their legal obligations.In addition, for those following a formal course of study, the contents will prove to be particularly useful to students undertaking the Institute of Quality Assurance's Associate Membership examination: Principles and Techniques of Quality Assurance.
