Resumen
AbstractAn element of a free group F is called almost primitive in F, if it is primitive in every proper subgroup containing it, though not in F itself. Several examples of almost primitive elements (APEs) are exhibited. The main results concern the behaviour of proper powers wℓ of certain APEs w in a free group F (and, more generally, in free products of cycles) with respect to any subgroup H containing such a power “minimally“: these assert, in essence, that either such powers of w behave in H as do powers of primitives of F, or, if not, then they “almost” do so and furthermore H must then h

Resumen
The key result linking the additive and multiplicative structure of a finite field is the Primitive Normal Basis Theorem; this was established by Lenstra and Schoof in 1987 in a proof which was heavily computational in nature. In this thesis, a new, theoretical proof of the theorem is given, and new estimates (in some cases, exact values) are given for the number of primitive free elements. A natural extension of the Primitive Normal Basis Theorem is to impose additional conditions on the primitive free elements; in particular, we may wish to specify the norm and trace of a primitive free elem

Ce travail est fondé sur la théorie des bigèbres bidendriformes, développée par Foissy, qui sont des algèbres de Hopf particulières où le produit et le coproduit peuvent être scindés en deux. Son théorème principal est: Une bigèbre bidendriforme est générée librement par ``l'espace des éléments totalement primitifs'' en tant qu'algèbre dendriforme. Une conséquence est l'auto-dualité des bigèbres bidendriformes.Parmi les nombreuses algèbres de Hopf, Hivert a défini l'algèbre des fonctions quasi-symétriques en mots, notée WQSym.

Perception plays a central role in such humans' motion guidance skills as precision rotorcraft landing or driving a car. This paper investigates the information available in visible cues, relative to a first-person motion guidance task, in terms of sensory-motor guidance primitives. Human subjects performed a motion guidance task in a 3D simulation system, using only visual information. Guidance primitive patterns were identified from recorded subject motion and perception behavior.

The cone, the sphere, and the cylinder are geometric solids derived from a circle. Within our contemporary digital framework, a cone is a singular object that is a built-in component in most software platforms, a primitive. The same could be said for the sphere or the cylinder. However, these massive and apparently singular forms are composed of sets of simple geometric elements: the circle and the point. In the history of architectural drawing, the ability to break down the cone, the sphere, and the cylinder into specific geometric properties has made these figures not only significant formal

4D printing is the process through which a 3D printed object or primitive is transformed into another structure under the influence of external energy input such as temperature, light or other extertal stimuli. The 4th dimension is the time in which the primitive changes its appearance. In most cases, the shape changes. We call this a self-assembly or self-transformation process. In the process of printing a primitive, capable of transforming themselves from one shape to another, we often encounter combinations of one or two thermoplastic materials that have different thermal and physico-mecha

This paper describes our work in creating and using new bond graph primitive elements to represent time-varying and/or frequency-dependent effects in engineering systems.

In traditional solid modeling the boundaries of the solid are represented using parametric equations.

In this paper, an implicit representation scheme for solids is presented where the boundaries of primitive solids are defined using implicit equation of surfaces. To ensure that the equations are axis independent, the characteristic functions for the implicit equations are defin
