Unique geodesics for Thompson's metric [PDF]

open access: yes, 2013
In this paper a geometric characterization of the unique geodesics in Thompson's metric spaces is presented. This characterization is used to prove a variety of other geometric results.

The parametrization of interior algebras

open access: yesMathematische Zeitschrift, 1993
Let \(G\) be a finite group, and let \(\mathcal O\) be a suitable ring of coefficients. To every indecomposable \({\mathcal O} G\)-lattice \(M\), there are attached three invariants: (1) its vertex \(P\), a subgroup of \(G\), (2) its source \(L\), an indecomposable \({\mathcal O} P\)-lattice, (3) a multiplicity module \(W\), an indecomposable ...

Risk‐aware safe reinforcement learning for control of stochastic linear systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Interior Point Methods for Massive Support Vector Machines [PDF]

open access: yes, 2000
We investigate the use of interior point methods for solving quadratic programming problems with a small number of linear constraints where the quadratic term consists of a low-rank update to a positive semi-de nite matrix. Several formulations of the

Interior Algebras and Topology

open access: yes, 1990
In this thesis connections between categories of interior algebras and categories of topological spaces, and generalizations of topological concepts to interior algebras, are investigated. The following are some of the most significant results we obtain: The establishment of a duality between topological spaces and complete atomic interior algebras ...

Uniform Gas Flow Distribution into Several Partial Flows under Consideration of Closable Outlets

open access: yesChemie Ingenieur Technik, EarlyView.
The uniform distribution of a gas flow into several partial flows poses a challenge in various technical fields. This study presents a static flow distributor design that ensures an equal distribution of an inlet gas flow regardless of the flow rate and the number of open outlets.

A Mizuno-Todd-Ye predictor-corrector infeasible-interior-point method for symmetric optimization with the arc-search strategy

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we propose a Mizuno-Todd-Ye predictor-corrector infeasible-interior-point method for symmetric optimization using the arc-search strategy.

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Bi-parameter Potential theory and Carleson measures for the Dirichlet space on the bidisc

open access: yesDiscrete Analysis, 2023
Bi-parameter potential theory and Carleson measures for the Dirichlet space on the bidisc, Discrete Analysis 2023:22, 58 pp. Carleson measures arise naturally when considering harmonic or holomorphic extensions from the boundary of a domain to the ...

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.
