Efecto de la zona de contacto entre fibra y matriz en las propiedades de fractura de materiales compuestos sometidos a carga transversal
(Grupo Español de Fractura, 1997)
El presente trabajo trata de dilucidar si en presencia de despegues entre fibra y matriz, se produce contacto circunferencial entre ambas fases cuando el conjunto está sometido a carga transversal a la fibra. Se utiliza ...

A Requirements Elicitation Approach Based in Templates and Patterns
(1999)
One of the main problems of requirements elicitation is expressing customer requirements in a form that can be understood not only by requirements engineers but also by noncomputer professional customers and users. The ...

Historical evolution of the Abalario lagoon complexes (Doñana Natural Park, SW Spain)
(Asociación Ibérica de Limnología, 1999)
This work aims to demostrate which factors have determined surface drainage and distribution of the present-day hygrophytic vegetation of Abalario, in Doñana Natural Park (Huelva). The area is difficult to interpret because ...

An algorithm for computing the first homology groups of CDGAs with linear differential
(Research Institute for Symbolic Computation, 1999)
We design here a primary platform for computing the basic homological information of Commutative Differential Graded Algebras (brie y, CDGAs), endowed with linear differential. All the algorithms have been implemented ...

Determining asymptotic behavior from the dynamics on attracting sets
(Springer, 1999-04)
Two tracking properties for trajectories on attracting sets are studied. We prove that trajectories on the full phase space can be followed arbitrarily closely by skipping from one solution on the global attractor to ...

Computing Cocycles on Simplicial Complexes
(Springer, 1999)
In this note, working in the context of simplicial sets [17], we give a detailed study of the complexity for computing chain level Steenrod squares [20, 21], in terms of the number of face operators required. This analysis ...

On regularization in superreflexive Banach spaces by infimal convolution formulas
(Polish Academy of Sciences, Institute of Mathematics, 1998)
We present here a new method for approximating functions defined on superreflexive Banach spaces by differentiable functions with α-H¨older derivatives (for some 0 < α ≤ 1). The smooth approximation is given by means of ...

Determination of Polyethylene Glycols in Water by Reversed-Phase High-Performance Liquid Chromatography
(Elsevier, 1996)
This paper describes an RP-HPLC method to characterize the ozonation products of polyethylene glycols (PEGs) (general formula HO(CH 2CH 2O) n -H) with original mass 5000. Samples with different pH and ozonation times were ...

A unified approach to network location problems
(John Wiley and Sons, 1999)
In this paper we introduce a new type of single facility location problems on networks which includes as special cases most of the classical criteria in the literature. Structural results as well as a finite dominating set ...
