This study assesses the ability of innovation diffusion theory to predict the adoption intention of organizations for financial EDI. Six factors potentially affecting adoption intention were studied: relative advantage, compatibility, complexity, observability, trialability, and risk (operational and strategic). Both present and future adoption intentions were measured, The questionnaire was de...

Electric drives control without shaft sensors has been an active research topic for almost three decades. It consists of estimating the rotor speed and/or position from the currents and voltages measurement. This paper deals with the observability conditions of electric drives in view of sensorless control. The models of such systems are strongly nonlinear. For this reason, a local observabilit...

Conewise linear systems are dynamical systems in which the state space is partitioned into a finite number of nonoverlapping polyhedral cones on each of which the dynamics of the system is described by a linear differential equation. This class of dynamical systems represents a large number of piecewise linear systems, most notably, linear complementarity systems with the P-property and their g...

This paper investigates the unknown input observability problem in the nonlinear case under the assumption that the unknown inputs are differentiable functions of time (up to a given order). The goal is not to design new observers but to provide simple analytic conditions in order to check the weak local observability of the state. The analysis starts by extending the observability rank conditi...

Using geometric concepts from observability theory for nonlinear systems, we propose an approach for parameter estimation for linearly and nonlinearly parameterized systems. The proposed approach relies on extending a parameter estimation problem to a state estimation problem by introducing the parameters as auxiliary state variables. Applying tools from geometric nonlinear control theory we es...

We present new results on reconstruction of the shape and motion of an unknown object using tactile sensors without requiring object immobilization. A robot manipulates the object with two flat palms covered with tactile sensors. We model the full dynamics and prove local observability of the shape, motion and center of mass of the object based on the motion of the contact points as measured by...

A new concept of partially defined system on a singular set is introduced. The setting is based on sheaf theory, and on a concept of locally integrable vector field on a differentiable space, introduced by K.Spallek. Short introductions to both areas are provided. The results consist of accessibility and observability criteria. They extend classical theorems as well as local observability crite...

By means of a direct and constructive method based on the theory of semi-global C solution, the local exact boundary observability is established for one-dimensional first order quasilinear hyperbolic systems with general nonlinear boundary conditions. An implicit duality between the exact boundary controllability and the exact boundary observability is then shown in the quasilinear case. Mathe...
