Stevens Institute of Technology Hoboken, NJ, USA {hwang,[email protected]} Abstract. We study the privacy threat by publishing data that contains full functional dependencies (FFDs). We show that the cross-attribute correlations by FFDs can bring potential vulnerability to privacy. Unfortunately, none of the existing anonymization principles can effectively prevent against the FFD-based priv...

exp(2 i( p 1 i ) are the eigenvalues of the Milnor monodromy and their integral part is determined by the Hodge ltration of the mixed Hodge structure. This notion was rst introduced by Steenbrink [11]. By [14] the exponents are constant under -constant deformation of f . In particular, they depend only on f 1 (0). They express the vanishing order (up to the shift by one) of the period integrals...

In th i s paper we present a novel improvement to existing schemes for a b r u p t shot change detection. Existing schemes declare a shot change whenever t h e f rame to f rame histogram difference (FFD) value is above a particular threshold. In such a n approach, a high value for t h e threshold results in a small number of false a larms a n d a large number of missed detections while a low va...

Skinning geometry effectively continues to be one of the more challenging and time consuming aspects of character setup. While anatomic and physically based approaches to skinning have been investigated, many skinned objects have no physical equivalents. Geometric approaches, which are more general and provide finer control, are thus predominantly used in the animation industry. Free-form defor...

We present a new approach to surface tracking applied to 3D medical data with a deformable model. It is based on a parametric model composed of a superquadric t followed by a Free-Form Deformation (FFD), that gives a compact representation of a set of points in a 3D image. We present three diierent approaches to track surfaces in a sequence of 3D cardiac images. From the tracking, we infer quan...

This paper is a summary of the results we presented at the Feature Panel Session of the 1997 ASME Computers in Engineering Conference. Five participating groups submitted a total of nine test parts for feature recognition. To these test parts, we have applied our feature recognition method using a convex decomposition method called Alternating Sum of Volumes with Partitioning (ASVP). By applyin...

The main objective of this paper is to investigate the performance trade off with MSK, BPSK and QAM_64 modulation techniques. Investigations have been reported to compare the performance and tradeoffs of MSK, BPSK and QAM_64 modulation schemes. Here modulation schemes have been identified which gives significant performance improvement over the other based on energy consumption and power recept...

Remarks References Acknowledgement Electronic Availability In recent years I have computed versal deformations of various singularities, partly by hand, but mostly with the program Macaulay. I explain here how to do these computations. As a...

We construct quantum deformation of Poincaré group using as a starting point SU(2, 2) conformal group and twistor-like definition of the Minkowski space. We obtain quantum deformation of SU(2, 2) as a real form of multi-parametric GL(4, C) q ij ,r. It is shown that Poincaré subgroup exists for special nonstandard one-parametric deformation only, the deformation parameter r being equal to unity....
