Nonlinear Programming And Variational Inequality Problems

RRP $102.99

Since I started working in the area of nonlinear programming and, later on, variational inequality problems, I have frequently been surprised to find that many algorithms, however scattered in numerous journals, monographs and books, and described rather differently, are closely related to each other. This book is meant to help the reader understand and relate algorithms to each other in some intuitive fashion, and represents, in this respect, a consolidation of the field. The framework of algorithms presented in this book is called Cost Approxi- mation. (The preface of the Ph.D. thesis [Pat93d] explains the background to the work that lead to the thesis, and ultimately to this book.) It describes, for a given formulation of a variational inequality or nonlinear programming problem, an algorithm by means of approximating mappings and problems, a principle for the update of the iteration points, and a merit function which guides and monitors the convergence of the algorithm. One purpose of this book is to offer this framework as an intuitively appeal- ing tool for describing an algorithm. One of the advantages of the framework, or any reasonable framework for that matter, is that two algorithms may be easily related and compared through its use. This framework is particular in that it covers a vast number of methods, while still being fairly detailed; the level of abstraction is in fact the same as that of the original problem statement.


The New Consumer Online

It's a new world online, where consumers can publish their writing and gain a public presence, even a mass audience. This book links together blogging, writing reviews for Yelp, and creating pinboards for Pinterest, all of which provide ordinary people the opportunity to display their tastes to strangers. Edward McQuarrie shows how the operation of taste in consumption has been changed by the Internet and offers a fresh perspective on why websites like Yelp and Pinterest have become so successful. Drawing on Bourdieu and Campbell to support his thesis, Edward McQuarrie uncovers what is new online by: * presenting a sociological perspective on what consumers do online and contrasting it to more familiar economic, psychological and ethnographic views * reinterpreting Bourdieu's idea of cultural capital to understand the success of fashion bloggers * showing how the meaning of taste and what it means to dress fashionably have changed with the Web * explaining why online reviews cannot be considered word-of-mouth and therefore cannot be understood using that idea * examining why Pinterest is so attractive to female consumers while relating Pinterest to Walter Benjamin's ideas about how mechanical reproduction changes the meaning of art. This book will be valuable to students and scholars interested in consumer research, marketing, and sociology, specifically those who seek an alternative to purely psychological and economic explanations for what consumers do online.

Thisvolumecontainsacollectionofpapersbyinternationalexpertsingeoph- ical ?uid dynamics, based upon presentations at a colloquium held in memory of Pedro Ripa on the ?rst anniversary of his untimely death. They review or present recent developments in hydrodynamic stability theory, Hamiltonian ?uid mechanics, balanceddynamics, waves, vortices, generaloceanographyand the physical oceanography of the Gulf ofCalifornia; all of them subjects in which Professor Ripamadeimportant contributions. His work, but also his friendly spiritandkindnesswerehighly regardedandappreciatedby colleagues and students alike around the world. This book is a tribute to his scienti?c legacy and constitutes a valuable reference for researchers and graduate s- dents interested in geophysical and general ?uid mechanics. Earlyin his career asa physicaloceanographer, Pedro Ripa made two la- mark contributions to geophysical ?uid dynamics. In 1981, he showed that the conservation of the potential vorticity is related to the invariance of the eq- tions of motion under the symmetry transformationsof the labels that identify the ?uid particles. That is, potential vorticity conservation is a consequence, via Noether's theorem, of the particle re-labelling symmetry. Two years later he published a paper entitled "General stability conditions for zonal ?ows in a one-layer model on the beta-plane or the sphere," where he established nec- sary conditions for stability in the shallow water equations, nowadays known as "Ripa's Theorem. " This is one of the very few Arnol'd-like stability con- tions that goes beyond two-dimensional or quasi-geostrophic ?ow, and stands alongside other famous stability criteria in making the foundations of the ?eld.
