Conferences Books

This is a collection of the pick of the best papers presented at GIS UK-93. The content varies widely since the field of GIS is large but are of a high standard throughout. Half the chapters, such as the well written one on image extraction from noisy sources are practical accounts of commercial systems rather than theoretical investigations.

Mere words are insufficient, as it must be experienced. This is for those who are into a prayer life on their own.

1992 was designated as the International Space Year by the space agencies of various countries. This book has the proceedings of the Kyoto conference, that attracted researchers from all over the world. Many of the papers are written at the level for research journals, and the reader needs background in those fields.

There are summaries of space exploration efforts of several countries. One interesting paper talks about the Chinese program. A lot of it was directed at satellite analysis of China's land mass. To measure deforestation, and to monitor and evaluate natural disasters like flooding in the coastal plains and forest fires.

The proceedings show a very active global space program.

Written for those who are not familiar to the subject, the author gives a brief but fairly effective overview of the subject of algebraic K-theory. Once thought to be of interest only to pure mathematicians, K-theory has now found applications to high energy physics and cryptography. Higher algebraic K-theory is not covered, the author realizing that very advanced technical machinery is needed for such material. The notes could be used though as an introduction to higher K-theory and Quillen's construction of K-groups for categories with exact sequences.

The author begins the lectures with stating the main goal of the book, namely for proving that for the polynomial ring A in N variables over the integers or integers modulo p, the general linear group of n by n matrices GL(n,A) over this ring is finitely generated for n greater than or equal to N + 3. To meet this goal he reviews the properties of elementary matrices in lecture 1. For a ring A, by considering the elementary subgroups E(n,A) of GL(n,A), these subgroups consisting of matrices satisfying certain relations, the author shows that for a surjective ring homomorphism between rings A and A', the homomorphism from E(n,A) to E(n,A') is surjective, even though it is not for GL(n,A) to GL(n,A'). E(n,A) is shown to be stable under transposition and shown to be commutator subgroup of GL(n,A) for large n. This is the origin of the stability issues in K-theory, and these are discussed in lecture 2. The author shows just why it is advantageous to consider taking the union GL(A) of GL(n,A) (and E(n,A)) for all n and why stability is important in the proof of the above result.

The "Whitehead group" K(1,A) is defined as GL(A)/E(A), and its use in the proof of the theorem results from the map GL(n,A)/E(n,A) to K(1,A) being a bijection for large n and that K(1,A) is finitely generated. Following this matrix characterization of K(1,A), the author reduces the proof of the theorem to showing that for a "regular" ring A, every unipotent element in GL(A) represents 0 in K(1,A), and that the rings in the theorem are indeed regular. Noting the analogy between determinants of matrices and determinants of endomorphisms of vector spaces, the author begins the proof of these assertions with a different description of K(1,A). This description involves the consideration of Grothendieck and Whitehead groups of categories with exact sequences.

The Whitehead group is now defined as the quotient of the Grothendieck group, the latter being the abelian group whose generators are essentially isomorphism classes of objects from an admissible Abelian category. The Whitehead group K(1,A) for a ring A is then related to the Whitehead group K(1,M) for an admissible category M. This definition is due to Grothendieck and involves showing that their is an isomorphism between K(1,A) and K(1, P(A)) where P(A) is the category of finitely generated projective A-modules. P(A) is not abelian, and therefore must be enlarged, without changing K(1,A), to one that is. The author shows that P(A) must be abelian in order to kill unipotents K(1,A). The enlarged P(A) is abelian as long as A is regular, the latter meaning that A is right Noetherian and that any finitely generated A-module has finite homological dimension. As the name implies, homological dimensions involves some discussion of homology theory, and is defined to the least n for which there is a projective resolution of the A-module of length n. The proof of the above theorem then follows, as the author shows, from Hilbert's syzygy theorem.

Like so many of the "hard" sciences, mathematics suffers from a perception complex. The public view of the practice and practitioners is that of a hopeless muddle of esoteric babble. But to paraphrase E. T. Bell, "mathematicians are as human as the rest, sometimes more so." One could make a solid argument that human essence can be boiled down to the creation and appreciation of art, employing a strategy in playing games with the only goal that of winning a non-essential prize, doing things for the mental exercise and seeing patterns where none is immediately obvious. All of these items are found in applied mathematics and in this case it is called recreational mathematics.
No artwork requires more thought to understand than that of M. C. Escher, where so many objects start as one thing and are somehow metamorphed into others. Many of the current ideas of fractals can be found in his drawings. So many "simple" games that we are exposed to have strategies that are mathematical in nature. But some, like chess, seem to defy solid mathematical analysis and show us once again how powerful the human computer really is. As the numbers of such puzzles appearing in newspapers and magazines indicates, a large percentage of the public enjoys a good mental tickler.
This collection is a distillation of those thoughts, featuring mathematical explanations of most. The works here show once again that the distinction between mathematics and the rest of the world is an artificial one put up by small minds. Mathematics is a joyous endeavor that provides more joy and frustration than any other ever imagined by intellects on par with that of humans. It is a joy to read about people doing mathematics for no other reason than recreation. It is also sad to realize that so many people who proudly wear a badge of mathematical illiteracy are so far gone that the do not realize it when they are employing mathematics in a recreational manner. For a short time, one of the best-selling books was one describing how to solve the puzzle known as "Rubik's Cube." As is explained here, the solution is based on beginning group theory.
A welcome addition to the literature, this report of the Strens conference is refreshing. For it shows mathematicians and their ilk having fun doing mathematics. To be blunt, that is something that the public simply does not understand.

Mr. Caropreso has gathered collection of information into one cohesive work with a sense of structure and purpose. Top experts in their fieds have provided source material and Mr. Caropreso has distilled it into a volume of great interest.

This book has been updated. The updated version will appear as: Mediation & Conference Programs in the Federal Courts of Appeals : A Sourcebook for Judges and Lawyers,
Second Edition

2004

The second edition will be available in 2006.

MICCAI, as a merging conference of VBC(Visualisation in Biomedical Computing),MRCAS(Medical Robotics and Computer Asisted Surgery) and CVRMed(Computer Vision, Virtual Reality and Robotics in Medicine)- really present some high quality scientific papers in medical imaging. We can see that from the high percentage refusal of the submiting paper.

The book collected the accepted paper for MICCAI in 1999. It covers the topic of Data-Driven Segmentation, Segmentation Using Structural Models, Image Processing and Feature Detection, Surfaces and Shape, Measurement and Interpretation,Spatiotemporal and Diffusion Tensor Analysis, Registration and Fusion, Visualization and Image-Guided Intervention. From this book you can see the detail of most recent development, some of them comes from very famous researcher and scientists working long time in this area. And I found some papers shown in this book have their further publishing in the high impact journals such as IEEE Medical imaging, Medical Image Analysis and so on.

So my brief conclusion is this is a very nice book for the people working in the area of medical imaging and related research.
