Optic Flow and Beyond (Synthese Library)

Book Description

Optic flow provides all the information necessary to guide a walking human or a mobile robot to its target. Over the past 50 years, a body of research on optic flow spanning the disciplines of neurophysiology, psychophysics, experimental psychology, brain imaging and computational modelling has accumulated. Today, when we survey the field, we find independent lines of research have now converged and many arguments have been resolved; simultaneously the underpinning assumptions of flow theory are being questioned and alternative accounts of the visual guidance of locomotion proposed. At this critical juncture, this volume offers a timely review of what has been learnt and pointers to where the field is going.

Book Description

Comment poser et résoudre les équations de Maxwell ? On présente ici les outils nécessaires : formulations faibles, éléments d’arêtes, méthodes intégrales, en insistant sur la modélisation, c’est-à-dire la « mise en équations » de situations concrètes : il y a en effet, pour chaque catégorie de problèmes en électrotechnique (chauffage par induction, machines et moteurs électriques, cavités résonnantes, etc.), un modèle mathématique approprié, qu’il faut savoir dériver des équations fondamentales. Pour chacun des modèles étudiés dans ce livre (« Maxwell complet », « conduction », « ondes en milieu borné », etc.) on donne la formulation appropriée et la version « discrétisée », c’est-à-dire exploitable sur un ordinateur, que la méthode des éléments finis permet d’en déduire.

Depuis sa rédaction, ce cours a été enseigné dans plusieurs formations doctorales européennes, destinées à des ingénieurs en électrotechnique et à des étudiants en analyse numérique. La présente réédition a été revue et corrigée en fonction de cette expérience, avec une bibliographie complétée. Bagage mathématique requis: algèbre et analyse numérique linéaire, et quelque familiarité avec la méthode des éléments finis. On ne suppose pas de connaissances préalables en électricité.

Book Description

Differential geometry techniques have very useful and important applications in partial differential equations and quantum mechanics. This work presents a purely geometric treatment of problems in physics involving quantum harmonic oscillators, quartic oscillators, minimal surfaces, and Schrödinger's, Einstein's and Newton's equations. Historically, problems in these areas were approached using the Fourier transform or path integrals, although in some cases (e.g., the case of quartic oscillators) these methods do not work. New geometric methods are introduced in the work that have the advantage of providing quantitative or at least qualitative descriptions of operators, many of which cannot be treated by other methods. And, conservation laws of the Euler–Lagrange equations are employed to solve the equations of motion qualitatively when quantitative analysis is not possible.

Main topics include: Lagrangian formalism on Riemannian manifolds; energy momentum tensor and conservation laws; Hamiltonian formalism; Hamilton–Jacobi theory; harmonic functions, maps, and geodesics; fundamental solutions for heat operators with potential; and a variational approach to mechanical curves. The text is enriched with good examples and exercises at the end of every chapter.

Geometric Mechanics on Riemannian Manifolds is a fine text for a course or seminar directed at graduate and advanced undergraduate students interested in elliptic and hyperbolic differential equations, differential geometry, calculus of variations, quantum mechanics, and physics. It is also an ideal resource for pure and applied mathematicians and theoretical physicists working in these areas.

Book Description

Authoritative British editions of the 14 Variations, rich with melody and vibrant rhythms, each revealing a facet of a central theme never fully expressed and each depicting an unnamed friend of the composer. Also includes 4 of the 5 stirring "Pomp and Circumstance" Marches.

Good deal.......2007-07-27

This edition of Elgar's Enigma Variations is a very high quality print with a reasonable price. Both for study or performance purposes it is a choice to everyones personal library.

Great Score - But Incomplete.......2005-04-04

Two of the most popular works by Sir Edward Elgar(1857-1934) are
the "Enigma Variations" (a theme followed by 14 variations -
1-12 being musical sketches of his friends, the 13th for his wife
with the final variation depicting the composer himself) and
the 5 "Pomp And Circumstance" marches.

I feel that Dover presents these works(in full score)in a way that is very clearly read and well presented.

The only problem I have with this compilation of Elgar's works has to do with the omission of Pomp And Circumstance March No. 5 (in C Major). Where is it? No. 5's liveliness is sorely missing from this group of 5 marches that Elgar wrote for many
various occasions (not just for graduations).

Regardless, I highly recommend buying this score collection.Enjoy the rich orchestration that Elgar uses in his various works
You'll see why Elgar is described as the Englishman who was credited as being one of the last true Romantic composers.

Book Description

Noted writers on art, culture, and the tropical Americas, Richard and Sally Price have crafted a mystery at the intersections of art and anthropology. Drawing readers into their quest for a solution, they build an unusual partnership between text and pictures, daringly expanding the possibilities of academic discourse. Enigma Variations--in the tradition of The Recognitions and The Crying of Lot 49--is an entertainment as readable for its intellectual power as for its irresistible drama.

Suspenseful Cultural Anthropology - A New Genre.......2004-07-29

I had to continually remind myself that this remarkable story was indeed fiction and not a scholarly account of a factual occurrence. I had actually purchased this book believing it to be a descriptive work of field anthropology. Enigma Variations was published by Harvard University Press, the authors acknowledged their fellowships from the John Simon Guggenheim Memorial Foundation and the National Endowment for the Humanities, every page is illustrated with scanned images of Saramakan art objects, and the footnotes referenced genuine scholarly publications. I did not immediately realize that this fascinating story was actually a rare blend of cultural anthropology and suspenseful fiction.

Richard Price and Sally Price have individually and jointly published scholarly works with titles like Stedman's Surinam: Life in an Eighteenth Century Slave Society, The Guiana Maroons, Primitive Art in Civilized Places, and Saramaka Social Structure. According to the book cover, they divide their time between rural Martinique and the College of William and Mary in Virginia.

In this short novel two anthropologists are asked to appraise a remarkable set of museum quality Saramakan musical instruments that are offered for sale. In following their investigations we readers learn about art smuggling, art renovation, and art forgery, and gradually discover that the ethical distinction between original and forged art can become quite blurred.

Enigma Variations is an exceptional book that defines an entirely new genre. I highly recommend this fascinating work.

Curiosity: This soft cover publication by Harvard University Press is printed on high quality, vanilla colored paper. The pages were bound backward in my discounted copy.

An unexpected pleasure.......2000-10-21

Richard and Sally Price are practicing anthropologists who have written a novel about some of the non-academic aspects of their work. Based on their real experiences, this book describes a detective hunt to establish the authenticity of some South American tribal and slave artifacts. But a simple yes/no question quickly blurs into shades of grey as they worm their way through collectors who 'restore' pieces, native carvers who mix styles to please buyers and museum officials trying to justify monies spent.

The book provides a fascinating philosophical discussion of authenticity and the differences between the way the art world and the academic world define it. Every page includes a photograph of an artifact discussed in the story, only at the end do we get a glimpse of which were genuine and which were not.

Book Description

Elgar's Variations for Orchestra, commonly known as the 'Enigma' Variations, marked an epoch both in his career, and in the renaissance of English music at the turn of the century. The first extended study of the work, this Cambridge Music Handbook contains historical information concerning the conception and writing of the work, an extended musical discussion requiring only a little technical knowledge of music, and a fascinating survey of the "solutions" to the mystery implied by the title of Elgar's most famous work.

Book Description

Viewing the contested theme Comparative Law as an `Enigma', this book explores its fundamental issues as sub-themes, each covered in two variations. After the Overture, the author pulls some strands together in the Intermezzo, uses a free hand in the Cadenza, and asks the reader to draw her own conclusions in the Finale. By this method two fundamentally opposed views are exposed in each Chapter. The what, why and how of comparative law, comparative law and legal education, comparative law and judges, and comparative law and law reform by transposition are explored. The author also examines current debates of comparative law such as law and culture, deconstruction of classifications, mixing systems, limits of comparability, convergence/non-convergence and ius commune novum.

Book Description

The 1899 debut of the Enigma Variations won Elgar renown throughout the British Isles and abroad, and the work remains one of his most widely performed works. Reprinted here from an authoritative English edition, the 14 variations teem with rich melodies and vibrant rhythms. Each portrays the personality of one of the Elgar's friends.

Fishmonkeys!.......2005-04-01

Ivan Arguelles, Enigma and Variations: Paradise is Persian for Park (Pantograph, 1995)

Another piece of Arguelles' epic masterpiece, Pantograph. In the greater scheme of things, I can't say enough good things about Pantograph (though lord knows I've tried in the reviews of the books I've so far managed to track down). It is a brilliant piece of work. Arguelles is, perhaps singlehandedly, keeping alive the true spirit of surrealism on American soil in this amazing journey; all we can do is hitch ourselves to the wagon and hope we survive the long, fast, exceptionally bumpy ride.

Enigma and Variations is, unfortunately, one of the less pleasant bumps, but don't let that in any way stop you from reading this alongside the other works in the piece. While Arguelles' stream-of-consciousness style remains intact, and his language is as precise and potent as ever, Enigma and Variations is the first piece of the puzzle I've read that actually seems as if it didn't flow forth from the pen, all of a piece, Athenalike. There is the air of craft about it, the air of revision.

Now, normally, this is not a bad thing in poetry. In fact, there are thousands upon thousands of pages of poetry extant in the world today that could use far more craft, and far more revision, than they have. The problem with it in this case is that Enigma and Variations is not quite the same swirling, chaotic, beautiful mass that the other books in the series (those I've read, at least) are. For a few pages, scattered here and there, the subconscious effect disappears, and we see the various obsessions spread out along their various threads. The evil spectre of message poetry rears its basiliskesque head and attempts to stare us in the face. Now, to Arguelles' great credit, said gorgon never fully rises out of its murky pit and takes over the place to break all the glass and make us pay to clean up the mess. At best, we find ourselves rubbing only slightly against the flying glass, and we emerge relatively unscathed. But still, when compared to such amazing journeys as Hapax Legomenon, Enigma and Variations is a bit rougher of a trip, just that much less readable than its brethren and sistren. Now, I rush to add that "just that much less readable" (emphasis there, strongly, on "just") means it's still better than 99% of what you'd pick up off a store shelf randomly, and it's still very much worth your while to hunt down and read. However, if you're an Arguelles newbie (and if so, I envy your your first dip into the bottomless black pool that is Arguelles), you may want to start with Hapax Legomenon or, outside the Pantograph epic, the brilliant Looking for Mary Lou: Illegal Syntax. The local china shop will thank you. *** ½
