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.

MMS will reshape mobile communication, making it more personal, versatile, and expressive than ever before. Drawing on the authors’ hands-on experience in developing, billing and delivering Multimedia Messaging Services (MMS), this innovative book addresses how MMS will affect existing network and business infrastructures. It demonstrates how the technologies and standards impact current business models of companies across the value chain, be they mobile operators, service providers, content providers, handset manufacturers or equipment vendors. Read MMS – Technologies, Usage and Business Models for: *An understanding of the standards and technologies that underpin the delivery of services – both at the application and network layers *An overview of the different players, their contribution to the value chain and the challenges they face *An insight into the fundamental changes to mail and billing systems for MMS *Guidance on regulatory requirements *Information on the technologies that ensure user uptake (such as security, location information, personalisation and context awareness) *A review of interoperability issues and usage scenarios "…this is not about putting a technology into a pocket, but about delivering a service to customers while mobile."
