On Sliding Mode Observers for Systems with Unknown Inputs [PDF]

, 2007
International audienceThis paper considers the problem of designing an observer for a linear system subject to unknown inputs. This problem has been extensively studied in the literature with respect to both linear and nonlinear (sliding mode) observers.

Indirect calibration between clinical observers - application to the New York Heart Association functional classification system

BMC Research Notes, 2011
Background Previous studies showed an inter-observer agreement for the NYHA classification of approximately 55%. The aim of this study was to calibrate the New York Heart Association (NYHA) classification system between observers, increasing its ...

Observing Functional Logic Computations [PDF]

, 2004
A lightweight approach to debugging functional logic programs by observations is presented, implemented for the language Curry. The Curry Object Observation System (COOSy) comprises a portable library plus a viewing tool. A programmer can observe data structures and functions by annotating expressions in his program.

Linear, Nonlinear, and Distributed-Parameter Observers Used for (Renewable) Energy Processes and Systems—An Overview

Energies
Full- and reduced-order observers have been used in many engineering applications, particularly for energy systems. Applications of observers to energy systems are twofold: (1) the use of observed variables of dynamic systems for the purpose of feedback ...

Reconstructing initial data using observers: error analysis of the semi-discrete and fully discrete approximations [PDF]

, 2010
A new iterative algorithm for solving initial data inverse problems from partial observations has been recently proposed in Ramdani et al. (Automatica 46(10), 1616-1625, 2010 ).

What Does Aspect−Oriented Programming Mean for Functional Programmers? [PDF]

, 2009
Aspect-Oriented Programming (AOP) aims at modularising crosscutting concerns that show up in software. The success of AOP has been almost viral and nearly all areas in Software Engineering and Programming Languages have become "infected" by the AOP bug ...

Comparison of MRI Results of Grafts Obtained by Unilateral Anterior Cruciate Ligament Reconstruction Either Using Anteromedial Portal Only or Transtibial Method with Contralateral Healthy Knee

Orthopaedic Journal of Sports Medicine, 2014
Objectives: Our aim is to compare graft angles and tibial tunnel insertion in patients undergone single bundle ligament reconstruction using anatomical anteromedial (AM) and transtibial (TT) method with the contralateral healthy knee by using MR imaging.
