MMS has evolved from the huge popularity of the SMS text service for GSM networks. It is a departure from the transport mechanism used for SMS (which is based on the GSM signalling channels) to the use of IP to transport messages within the MMS network. To this end MMS has similarities with Internet email and standard IETF protocols. As with any new technology it is difficult to accurately predict the position within the next 5 years, although based on previous experience with WAP and SMS it would be fair to say that these protocols will increase in usage over the next 5 years and become legacy for a further 5 years following which, users will migrate onto the next wave of messaging. Significant revenue growth and data usage is expected to be driven by consumer usage of MMS. But MMS technology offers more than just a broadening of message content. With MMS, it is not only possible to send your multimedia messages from one phone to another, but also from phone to email, and vice versa. This feature dramatically increases the possibilities of mobile communication, both for private and corporate use.Multimedia messaging will reshape the landscape of mobile communication, making it more personal, more versatile, and more expressive than ever before.MMS: Is the first book to address how MMS (and the use of IP to transport messages) will affect existing infrastructure and business modelsCovers the fundamental changes to mail and billing systemsIncludes future recommendations, such as interoperability and evolutionPresents an overview of the MMS technology componentsDrawing on the authors hands-on experience in the implementation of MMS technology (developing, billing and delivering services) at BT, this innovative book will appeal to engineering managers, network operators, market analysts, business decision makers, content providers and operator organizations.

This book provides a solid foundation and an extensive study for an important class of constrained optimization problems known as Mathematical Programs with Equilibrium Constraints (MPEC), which are extensions of bilevel optimization problems. The book begins with the description of many source problems arising from engineering and economics that are amenable to treatment by the MPEC methodology. Error bounds and parametric analysis are the main tools to establish a theory of exact penalisation, a set of MPEC constraint qualifications and the first-order and second-order optimality conditions. The book also describes several iterative algorithms such as a penalty-based interior point algorithm, an implicit programming algorithm and a piecewise sequential quadratic programming algorithm for MPECs. Results in the book are expected to have significant impacts in such disciplines as engineering design, economics and game equilibria, and transportation planning, within all of which MPEC has a central role to play in the modelling of many practical problems.

This is the first in a new series of contributed, refereed volumes devoted to research in optimization by Australasian researchers and their collaborators. These volumes are intended to have wide scope and include survey papers by established researchers providing up-to-date information on research directions. This volume contains survey papers on the Clarke subdifferential and differentiability in Banach spaces, algorithms for solving nonsmooth equations, and control parametrization schemes in optimal control. Other topics covered include convex optimization, generalized convexity in optimization, nonsmooth analysis, and algorithms using approximations of sub-differentials.

The world is charging towards the new network technologies of broadband and 3G, and new application technologies face the challenge of where they can be used. This book takes a pragmatic look at two particular application technologies - location and personalisation - and presents an understanding of the technical and business impact of these technologies. With a combination of overview papers, detailed technical case studies and a deep understanding of actual implementatio of these services within a telecommunications environment, this book will help those wishing to deliver improved services based on these capabilities. Other key topics covered include CRM and content management.

The one bad apple spoiling the whole barrel has become a common metaphor used with reference to risk culture in organisations. This "inside-out" perspective begins with the individual as the unit of analysis and follows with inferences to the broader environment. Since the Global Financial Crisis (GFC) of 2008, risk culture for many has become the explanation for shortcomings, poor decisions, and moral failures in organisations. This volume presents an institutional perspective of the forces that shape risk culture, and culture more generally, in organisations through a multi-disciplinary examination from a variety of leading academics and subject specialists. The authors demonstrate that firms play a role as manufacturers and managers of risk and they challenge common conceptions that attribute risk to chance circumstances or rogue behaviours. The foundational concepts needed for an institutional view of risk culture are highlighted with subsequent links to significant developments within society and firms.
