What is field theory?

JL Martin - American journal of sociology, 2003 - journals.uchicago.edu
Field theory is a more or less coherent approach in the social sciences whose essence is
the explanation of regularities in individual action by recourse to position vis-à-vis others …

Flat systems, equivalence and feedback

P Martin, RM Murray, P Rouchon - Advances in the control of nonlinear …, 2001 - Springer
Flat systems, an important subclass of nonlinear control systems introduced via differential-
algebraic methods, are defined in a differential geometric framework. We utilize the infinite …

An overview on the modeling of oilwell drilling vibrations

B Saldivar, I Boussaada, H Mounier, S Mondié… - IFAC Proceedings …, 2014 - Elsevier
In drilling operations, the drillstring interaction with the borehole gives rise to a wide variety
of undesired oscillations. The main types of drilling vibrations are torsional (stick-slip), axial …

Analysis and control of oilwell drilling vibrations

MBS Márquez, I Boussaada, H Mounier… - A Time-Delay Systems …, 2015 - Springer
Vibrations in mechanical systems are oscillations occurring without being intentionally
provoked. They often have detrimental effects on the system performance and may cause …

Controllability and observability of linear delay systems: an algebraic approach

M Fliess, H Mounier - ESAIM: Control, Optimisation and Calculus of …, 1998 - esaim-cocv.org
In this paper a model reference-based adaptive parameter estimator for a wide class of
hyperbolic distributed parameter systems is considered. The proposed state and parameter …

A simultaneous space‐time discretization approach to the inverse dynamics of geometrically exact strings

T Ströhle, P Betsch - International Journal for Numerical …, 2022 - Wiley Online Library

Solutions of neutral delay differential equations using a generalized Lambert W function

C Jamilla, R Mendoza, I Mező - Applied Mathematics and Computation, 2020 - Elsevier
The Lambert W function is defined by W (a) e W (a)− a= 0. One of the many applications of
the Lambert W function is in solving delay differential equations (DDEs). In 2003, Asl and …
