Inversion of a physical model of a trumpet [PDF]
Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003 We deal with the inversion of a physical model of a trumpet, i.e. how should the model be controlled in order to obtain a given sound. It is shown that this problem is ill-posed since an infinity of inputs can produce the same sound. Then, a criterion based on the slowness of the musician's gestures compared to the sound signal evolution is used: this ...

Inverse Procedural Modelling of Trees [PDF]
Computer Graphics Forum, 2014 AbstractProcedural tree models have been popular in computer graphics for their ability to generate a variety of output trees from a set of input parameters and to simulate plant interaction with the environment for a realistic placement of trees in virtual scenes. However, defining such models and their parameters is a difficult task.

On inverse problems modeled by PDE’s [PDF]
Matemática Contemporânea, 2000 We investigate the iterative methods proposed by Maz'ya and Kozlov (see [3], [4]) for solving ill-posed reconstruction problems modeled by PDE's. We consider linear time dependent problems of elliptic, hyperbolic and parabolic types. Each iteration of the analyzed methods consists on the solution of a well posed boundary (or initial) value problem. The

Feedback methods for inverse simulation of dynamic models for engineering systems applications [PDF]
, 2011 Inverse simulation is a form of inverse modelling in which computer simulation methods are used to find the time histories of input variables that, for a given model, match a set of required output responses.

Output Voltage Control of BESS Inverter in Stand-Alone Micro-Grid Based on Expanded Inverse Model
IEEE Access, 2020 This paper investigates robust output voltage control of battery energy storage systems (BESS) inverter in stand-alone micro-grid. The transfer function model between the output voltage and duty cycle of the BESS inverter is established, base on which ...

Approximation of Bayesian inverse problems for PDEs [PDF]
, 2010 Inverse problems are often ill posed, with solutions that depend sensitively on data. In any numerical approach to the solution of such problems, regularization of some form is needed to counteract the resulting instability.

Latin American Journal of Solids and StructuresIn the work, in order to solve the inverse problem, i.e. the problem of finding values of the additional quantities (mass, elasticity), the beam inverse model was proposed. Analysis of this model allows finding such a value of additional mass (elasticity)
