The ratedistortion function for source coding with side information at the decoder
 IEEE Trans. Inform. Theory
, 1976
"... AbstractLet {(X,, Y,J}r = 1 be a sequence of independent drawings of a pair of dependent random variables X, Y. Let us say that X takes values in the finite set 6. It is desired to encode the sequence {X,} in blocks of length n into a binary stream*of rate R, which can in turn be decoded as a seque ..."

the quantity R*(d). defined as the infimum of rates R such that (with E> 0 arbitrarily small and with suitably large n) communication is possible in the above setting at an average distortion level (as defined above) not exceeding d + E. The main result is that R*(d) = inf[Z(X,Z) Z(Y,Z)], where
The geometry of graphs and some of its algorithmic applications
 COMBINATORICA
, 1995
"... In this paper we explore some implications of viewing graphs as geometric objects. This approach offers a new perspective on a number of graphtheoretic and algorithmic problems. There are several ways to model graphs geometrically and our main concern here is with geometric representations that res ..."

that respect the metric of the (possibly weighted) graph. Given a graph G we map its vertices to a normed space in an attempt to (i) Keep down the dimension of the host space and (ii) Guarantee a small distortion, i.e., make sure that distances between vertices in G closely match the distances between
Small distortion and volume preserving embeddings for Planar and Euclidean metrics
, 1999
"... A finite metric space, (S,d) , contains a finite set of points and a distance function on pairs of points. A contraction is an embedding, h, of a finite metric space (S, d) into Rd where for any u, v E S, the Euclidean (&) distance between h(u) and h(v) is no more than d(u, v). The distortion of ..."

Fast Multiresolution Image Querying
, 1995
"... We present a method for searching in an image database using a query image that is similar to the intended target. The query image may be a handdrawn sketch or a (potentially lowquality) scan of the image to be retrieved. Our searching algorithm makes use of multiresolution wavelet decompositions ..."

of the query and database images. The coefficients of these decompositions are distilled into small "signatures" for each image. We introduce an "image querying metric" that operates on these signatures. This metric essentially compares how many significant wavelet coefficients the query
Informationtheoretic analysis of information hiding
 IEEE Transactions on Information Theory
, 2003
"... Abstract—An informationtheoretic analysis of information hiding is presented in this paper, forming the theoretical basis for design of informationhiding systems. Information hiding is an emerging research area which encompasses applications such as copyright protection for digital media, watermar ..."

of small distortions. In some cases, including the last two above, the hiding capacity is the same whether or not the decoder knows the host data set. It is shown that many existing informationhiding systems in the literature operate far below capacity. Index Terms—Channel capacity, cryptography
Staining of tissue sections for electron microscopy with heavy metals
, 1958
"... Heavy metals may be incorporated from solution into tissue sections for electron microscopy. The resulting increase in density of the tissue provides greatly enhanced contrast with minimal distortion. Relative densities of various structures are found to depend on the heavy metal ions present and on ..."

Curvature of the probability weighting function
 Management Science
, 1996
"... Empirical studies have shown that decision makers do not usually treat probabilities linearly. Instead, people tend to overweight small probabilities and underweight large probabilities. One way to model such distortions in decision making under risk is through a probability weighting function. We ..."

Inherited Wealth, Corporate Control, and Economic Growth: The Canadian Disease
 Concentrated Corporate Ownership

Much of many countries = capital is proffered to corporations controlled by a small number of very wealthy families. This could be desirable if these families provide optimal corporate management. This paper raises the po ..."

An Image Multiresolution Representation for Lossless and Lossy Compression
 IEEE TRANSACTIONS ON IMAGE PROCESSING
, 1996
"... We propose a new image multiresolution transform that is suited for both lossless (reversible) and lossy compression. The new transformation is similar to the subband decomposition, but can be computed with only integer addition and bitshift operations. During its calculation the number of bits ..."
