Aspects of duality theory for spaces of measurable operators
… measure space. In non-commutative integration theory, a von Neumann algebra takes over the role of the space of essentially bounded measurable functions. If the von Neumann algebra is semifinite, then there exists a faithful semifinite normal trace on it. Equipped with such a trace, a topology …

A Numerical Investigation Of The Canonical Duality Method For Non-Convex Variational Problems
… and numerical investigation of the canonical duality theory, which has been recently proposed as an alternative to the classic and direct methods for non-convex variational problems. These non-convex variational problems arise in a wide range of scientific and engineering applications, such as …

DUALITY IN NONLINEAR VECTOR OPTIMIZATION
… we attempted to give a systematic account of duality theory for a convex vector optimization nonlinear programming problem, In mathematical programming, duality means in association to, say a minimization problem, we maximize a related problem, called its dual. Occasionally, the dual problem …

Implementação de um algoritmo dual para a otimização de sistemas decomponíveis
… sets is sinthetized based on results from duality theory. Its appication to the outer linearized problem results in a convergent method for the solution of the original problem. A computer program has been developed.

Thrust Network Analysis : exploring three-dimensional equilibrium
… a defined envelope. Using projective geometry, duality theory and linear optimization, it provides a graphical and intuitive method, adopting the same advantages of techniques such as graphic statics, but offering a viable extension to fully three-dimensional problems. The proposed method is …

Economic Measurement of Consumers and Firms: A Model Consistent Approach
… Striking a delicate balance between the theory and art of modelling is examined as a way to promote economics as a social science. This is accomplished by looking at more traditional approaches to economics, especially those encapsulated in consumer theory and the theory of the firm, and …

p-primary torsion part of Bloch's cycle complex from Grothendieck's coherent duality point of view
… define a complex K_{n,X,log} via Grothendieck’s duality theory of coherent sheaves following [Kat87] and build up a quasi-isomorphism from the Kato-Moser complex of logarithmic de Rham-Witt sheaves \tilde \nu_{n,X} to K_{n,X,log} for the etale topology, and also for the Zariski topology under the …

Inverse optimization of discrete-time systems applied to human locomotion
… a particular focus on the relationship between duality theory and inverse optimization. We then proceed to describe our solution approach. Finally, we apply our approach to find a model of goal-directed human walking from experimental data with human subjects.

REVEALING ADDITIONAL INFORMATION ABOUT ELECTRICITY MARKET UNDERLYING POWER SYSTEM USING POWER SYSTEM PRINCIPLES AND PUBLISHED MARKET RESULTS
… estimation framework designed and structured on duality theory for estimation of some key parameters in electricity markets. Specifically, the framework uses financial transmission right (FTR) auction outcomes such as clearing prices and quantities to estimate implicit parameters of the …

On the slope filtration of [phi]-modules over the Robba ring
… characteristic formula and Tate local duality for p-adic representations. These results are expected to intervene in the duality theory for Selmer groups associated to de Rham representations. We introduce the notion of families of [phi]-modules which arises naturally from both rigid …

An analysis of subsidies within the plastics recycling industry
… to the regression analysis, the study builds the theory behind production and cost function analysis (in addition to the associated duality theory). However, due to the combination of the research question and the limited data availability, an alternative model was adopted, in order to explain as …

Optimization under moment, robust, and data-driven models of uncertainty
… hierarchy of moment relaxation and the moment duality theory. We then propose a moment-based uncertainty model for stochastic optimization problems, which addresses the ambiguity of probability distributions of random parameters with a minimax decision rule. We establish the model tractability …

DESIGN OF MULTIVARIABLE FEEDBACK CONTROLLERS: ITALIC-L(1)-OPTIMAL SYSTEMS
… of the error transfer function. Employing the duality theory in optimization, this problem is converted to a finite dimensional programming problem. In discrete-time systems, optimal solutions are obtained by solving linear programming problems and sets of linear equations. This result, …
