Combination of an adaptive multilevel SQP method and a space-time adaptive PDAE solver for optimal control problems
We present an adaptive multilevel generalized SQP method to solve PDAE-constrained optimization problems. It explicitly allows the use of independent integration schemes such that...

Integrated Rate and Credit Feedback Control for ABR Service in ATM Networks
We propose a ow-control scheme that combines the merits of credit- and rate-based ow-control schemes by applying direct control over both bandwidth and bu er resources. The goal...

Robust controller design by convex optimization based on finite frequency samples of spectral models
Abstract-- Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not gu...

Discrete Regularization for Perceptual Image Segmentation via Semi-Supervised Learning and Optimal Control
In this paper, we present a regularization approach on discrete graph spaces for perceptual image segmentation via semisupervised learning. In this approach, first, a spectral cl...

Control flow optimization for supercomputer scalar processing
Control intensive scalar programs pose a very different challenge to highly pipelined supercomputers than vectorizable numeric applications. Function call/return and branch instru...
