Systems of Controlled Functional Differential Equations and Adaptive Tracking
Abstract. An adaptive servomechanism is developed in the context of the problem of approximate or practical tracking (with prescribed asymptotic accuracy), by the system output, of...

Solving Differential Equations in Developmental Models of Multicellular Structures Expressed Using L-systems
Mathematical modeling of growing multicellular structures creates the problem of solving systems of equations in which not only the values of variables, but the equations themselv...

A partial differential equation approach to image zoom
We propose a new model for zooming digital image. This model, driven by a partial differential equation, will balance between linear zooming on homogenous zones to anisotropic dif...

The tau-cell: a new method for the implementation of arbitrary differential equations
In this paper we present the tau-cell, a building block based on a log-domain low-pass filter, which allows the creation of arbitrary differential equations using a cascade of the...

Finding all Hypergeometric Solutions of Linear Differential Equations
Hypergeometric sequences are such that the quotient of two successive terms is a fixed rational function of the index. We give a generalization of M. Petkov6ek’s algorithm to fi...
