A Novel Method for Optimal Control of Piecewise Affine Systems Using Semi-Definite Programming [PDF]
: In this paper, a novel optimal control design method by discontinuous quadratic Lyapunov function and continuous quadratic Lyapunov function for 2-dimensional piecewise affine systems via semi-definite programming and LMI constraints is proposed.In ...

El concepto de Rectángulo Equivalente para la caracterización de la forma de una cuenca
In this work the importance of the teaching of geometry as a modeler of the space in which people are immersed is rescued. For this, is showed the resolution of a problem related to a certain types of disciplines such as cartography, geography, and ...

Conjugacy problem in groups with quadratic Dehn function [PDF]
We construct a finitely presented group with quadratic Dehn function and undecidable conjugacy problem. This solves Rips’ problem formulated in 1994.

The focus for quasi-Newton methods is the quasi-Newton equation. A new quasi-Newton equation is derived for quadratic function. Then, based on this new quasi-Newton equation, a new quasi-Newton updating formulas are presented.

OSQP: an operator splitting solver for quadratic programs [PDF]
We present a general-purpose solver for convex quadratic programs based on the alternating direction method of multipliers, employing a novel operator splitting technique that requires the solution of a quasi-definite linear system with the same ...

Generalised L\"uroth expansions and a family of Minkowski's Question-Mark functions [PDF]
The Minkowski's Question-Mark function is a singular homeomorphism of the unit interval that maps the set of quadratic surds into the rationals. This function has deserved the attention of several authors since the beginning of the twentieth century ...
