Reference Tracking and Disturbance Rejection for Nonlinear Systems Using LPV Control
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT The Linear Parameter‐Varying (LPV) framework has been introduced with the intention to provide stability and performance guarantees for analysis and controller synthesis for Nonlinear (NL) systems through convex methods. By extending results of the Linear Time‐Invariant framework, mainly based on quadratic stability and performance using ...

Solutions to the direct and inverse navigation problems on the great ellipse
Journal of Geodetic Science, 2012 The Great Ellipse (GE) is the curve of intersection between the surface and a plane through the center of an ellipsoid. For arcs within a few thousands of kilometres it agrees within a few metres with the geodesic.

The extent and drivers of internal agglomeration of U.S. multi‐unit firms
Strategic Management Journal, EarlyView.Abstract Research Summary This paper examines the extent and determinants of internal agglomeration—the spatial clustering of establishments within firms. It introduces a novel methodology that benchmarks a firm's spatial footprint against that of comparable stand‐alone firms, yielding a firm‐level measure of internal agglomeration.

Concentration in cross‐border research collaborations and MNCs' knowledge creation in a host country
Strategic Management Journal, EarlyView.Abstract Research Summary This study elucidates the previously underexplored structural heterogeneity inherent in multinational corporations' (MNCs) internal linkages by examining the concentration of cross‐border collaborations among inventors within host countries.

Frames of quasi-geodesics, visibility and geodesic loops
, 2023 In this paper we give a characterization in terms of ``quasi-geodesics frames' of visibility and existence of geodesic loops for bounded domains in $\mathbb C^d$ which are Kobayashi complete hyperbolic and Gromov hyperbolic.

Structural Concrete, EarlyView.Abstract The decisive reinforcement of thick concrete members is often determined by the minimum reinforcement for crack control due to restraint stresses. In contrast to the heuristic design model in Eurocode 2, a mechanically sound methodology is only provided if the deformation compatibility is considered.

A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.
