Interior Point Methods in Semidefinite Programming with Applications to Combinatorial Optimization
 SIAM Journal on Optimization
, 1993
"... We study the semidefinite programming problem (SDP), i.e the problem of optimization of a linear function of a symmetric matrix subject to linear equality constraints and the additional condition that the matrix be positive semidefinite. First we review the classical cone duality as specialized to S ..."

TWO RESULTS ON SPECIAL POINTS
"... We show that there is a nowhere ccc σcompact space which has a remote point. We show that it is consistent to have noncompact σcompact separable space X such that every point of the remainder is a limit of a countable discrete subset of nonisolated points of X. This example shows that one canno ..."

The Nature and Growth of Vertical Specialization in World Trade
 Journal of International Economics
"... Abstract: Dramatic changes are occurring in the nature of international trade. Production processes increasingly involve a sequential, vertical trading chain stretching across many countries, with each country specializing in particular stages of a good’s production sequence. We document a key aspe ..."

and transport costs can lead to extensive vertical specialization, large trade growth, and large gains from trade. We formally illustrate these points by developing an extension of the DornbuschFischerSamuelson Ricardian trade model.
Special points on products of modular curves
, 2003
"... We prove the André–Oort conjecture on special points of Shimura varieties for arbitrary products of modular curves, assuming the Generalized Riemann Hypothesis. More explicitly, this means the following. Let n ≥ 0, and let Σ be a subset of C n consisting of points all of whose coordinates are jin ..."

Multidimensional Access Methods
, 1998
"... Search operations in databases require special support at the physical level. This is true for conventional databases as well as spatial databases, where typical search operations include the point query (find all objects that contain a given search point) and the region query (find all objects that ..."

Mean shift, mode seeking, and clustering
 IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 1995
"... Mean shift, a simple iterative procedure that shifts each data point to the average of data points in its neighborhood, is generalized and analyzed in this paper. This generalization makes some kmeans like clustering algorithms its special cases. It is shown that mean shift is a modeseeking proce ..."

Data Integration: A Theoretical Perspective
 Symposium on Principles of Database Systems
, 2002
"... Data integration is the problem of combining data residing at different sources, and providing the user with a unified view of these data. The problem of designing data integration systems is important in current real world applications, and is characterized by a number of issues that are interestin ..."

The tutorial is focused on some of the theoretical issues that are relevant for data integration. Special attention will be devoted to the following aspects
Quicktime VR  an imagebased approach to virtual environment navigation.
 In SIGGRAPH 95 Conference Proceedings,
, 1995
"... ABSTRACT Traditionally, virtual reality systems use 3D computer graphics to model and render virtual environments in realtime. This approach usually requires laborious modeling and expensive special purpose rendering hardware. The rendering quality and scene complexity are often limited because of ..."
