the analytic signal for magnetic anomalies was initially defined as a “complex field deriving from a complex potential” (nabighian, 1972). this function can be computed easily in the frequency domain, its real part is the horizontal derivative of the field and its imaginary part is the vertical derivative. analytic signal processing and interpretation requires few initial assumptions regarding ...

In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...

This paper addresses the problem of integrating free-form surfaces in a constrained object reconstruction. The objects of interest here have both simple shaped surfaces (e.g. planes and quadrics) and free-from surfaces. The goal is to ensure a global optimization of the object shape where neighbourhood relationships between free-from surfaces and analytic surfaces are also satissed. The scheme ...

Optimization is a classical notion in control theory. It is often required in engineering practice. As a case study, this paper represents an initial contribution to the formalization of the concept of optimization of hybrid systems and also explores its analytic and synthetic techniques. The illustrative case is a fluid double-tank example and the logical notation employed in the formalization...

We propose a self-organizing type of controller for a mobile robot. Rather than decompose the control task into subtasks and implement these (an analytic approach) we propose to use competence generators which generate, through a process of self-organization, the necessary competences (a synthetic approach). We have built a mobile robot and equipped it with a rst version of such a self-organizi...
