In this thesis a nonlinear model predictive control (NMPC) scheme is presented that is based on the concept of passivity. The proposed NMPC scheme takes advantage of the relationship between optimal control and passivity and the relationship between optimal control and model predictive control. This novel NMPC scheme, guaranteeing closedloop stability through the incorporation of a passivity-ba...

We introduce a multiresolution representation scheme for variable levels of detail of molecular shapes (shapes synthesized as sets of balls). In particular, we consider in our model the exact boundary computation of the the basic union of balls for CPK model and solvent accessible surface as well as the more complex rolling ball solvent contact surface and molecular skin. Our decimation/refinem...

This document is an initial proposal for a draft for a forthcoming ISO standard on publickey encryption. It is hoped that this proposal will serve as a basis for discussion, from which a consensus for a standard may be formed. Summary of Changes from version 2.0 (September 17, 2001) to version 2.1 (December 20, 2001) • Fixed a few minor typos, and added some references to supporting documents. ...

In this paper we will present an adaptive wavelet scheme to solvethe generalized Stokes problem. Using divergence free wavelets, theproblem is transformed into an equivalent matrix vector system, thatleads to a positive definite system of reduced size for thevelocity. This system is solved iteratively, where the applicationof the infinite stiffness matrix, that is sufficiently compressible,is r...

The undesired operation of zone 3 may be one of the most conspicuous protective relay features due to the incorrect zone 3 relay operations which have been conducive to the severity of blackouts. Therefore, determining the accurate zone 3 setting of the distance relay is deemed to be necessary. This paper focuses on the development of a new technique for calculating zone-3 setting of distance r...

With the growing importance of XML in data exchange, much research has been done in providing flexible query facilities to extract data from structured XML documents. Thereby, several path indexing, labelling and numbering scheme have been proposed. However, if XML data need to be updated frequently, most of these approaches will need to re-compute existing labels which is rather time consuming...

One of the key elements in the adaptive immune response is the presentation of peptides by the major histocompatibility complex (MHC) to the T cell receptors (TR) at the surface of T cells. The characterization of the TR/peptide/MHC trimolecular complexes (TR/pMHC) is crucial to the fields of immunology, vaccination and immunotherapy. In order to facilitate data comparison and cross-referencing...

Refinement operators for triangular meshes as used in subdivision schemes or remeshing are discussed. A numbering scheme is presented, covering all refinement operators that (topologically) map vertices onto vertices. Using this characterization, some special properties of n-adic and √ 3-subdivision are easy to see.
