A Multiphase Level Set Framework for Image Segmentation Using the Mumford and Shah Model
 INTERNATIONAL JOURNAL OF COMPUTER VISION
, 2002
"... We propose a new multiphase level set framework for image segmentation using the Mumford and Shah model, for piecewise constant and piecewise smooth optimal approximations. The proposed method is also a generalization of an active contour model without edges based 2phase segmentation, developed by ..."

the problems of vacuum and overlap; it needs only log n level set functions for n phases in the piecewise constant case; it can represent boundaries with complex topologies, including triple junctions; in the piecewise smooth case, only two level set functions formally suffice to represent any partition, based
DTP 95/39 THE VACUUM FUNCTIONAL AT LARGE DISTANCES
, 1995
"... For fields that vary slowly on the scale of the lightest mass the logarithm of the vacuum functional can be expanded as a sum of local functionals, however this does not satisfy the obvious form of the Schrödinger equation. For ϕ 4 theory we construct the appropriate equation that this expansion doe ..."

BUTP95/26 Vacuum functional and fermion condensate in the massive Schwinger model
, 2008
"... We derive a systematic procedure of computing the vacuum functional and fermion condensate of the massive Schwinger model via a perturbative expansion in the fermion mass. We compute numerical results for the first nontrivial order. ..."

DTP 95/47 Reconstructing the Vacuum Functional of YangMills from its Large Distance Behaviour
, 1995
"... For fields that vary slowly on the scale of the lightest mass the logarithm of the vacuum functional can be expanded as a sum of local functionals. For YangMills theory the leading term in the expansion dominates large distance effects and leads to an area law for the Wilson loop. However, this exp ..."

A Variational Level Set Approach to Multiphase Motion
 JOURNAL OF COMPUTATIONAL PHYSICS 127, 179–195 (1996) ARTICLE NO. 0167
, 1996
"... A coupled level set method for the motion of multiple junctions (of, e.g., solid, liquid, and grain boundaries), which follows the gradient flow for an energy functional consisting of surface tension (proportional to length) and bulk energies (proportional to area), is sin �1 developed. The approach ..."

 The TSQL2 Temporal Query Language
, 1995
"... Introduction Base tables supporting transaction time are evergrowing because all logical updates, including deletions, transform into insertions at the physical level. This contrasts snapshot tables where logical and physical deletion coincide. Logical deletion in TSQL2 was covered in 16. As there ..."

notion of vacuuming and associated concepts are introduced and motivated. It is shown that straightforward physical deletion may adversely affect the usefulness of query results and that special attention thus should be devoted to the design of appropriate vacuuming facilities. We then give reasons why
