Bilayer vesicles, such as liposomes and niosomes, are widely known as efficient delivery systems for drugs. Spherical vesicles consisting of amphipatic non-ionic surfactants named niosomes are arranged in one or more concentric bilayers. They can entrap both water and oil…

Software tools processing partially common set of data should share an understanding of what these data mean. Since ontologies have been used to express formally a shared understanding of information, we argue that they can be used to improve integration…

Nowadays, data intensive applications are in constant demand and there is need of computing environments with better intelligent capabilities than those present in today's Database Management Systems (DBMS). To build such systems we need formalisms that can perform complicate inferences,…

The concept of “approximate” searching has applications in a vast number of fields. Some examples are non-traditional databases (e. g. storing images, fingerprints or audio clips, where the concept of exact search is of no use and we search instead…

Most search methods in metric spaces assume that the topology of the object collection is reasonably regular. However, there exist nested metric spaces, where objects in the collection can be grouped into clusters or subspaces, in such a way that…

This paper focuses on prediction and prevention of seismic risk through a system for decision making. Data Warehousing and OLAP operations are applied, together with, data mining tools like association rules, decision trees and clustering to predict aspects such as…

Although researchers noted the importance of effective communication among stakeholders, it continues to be a challenge for requirements engineering. Communication can be considered as a management tool since communication allows organisation’s personnel to produce a cohesive enterprise view. In this…

Software engineering has entered a new era, the Internet and its associated technologies require a different conceptual framework for building and understanding software solutions.
Users ask to develop applications more rapidly, and software engineers need to ensamble systems from preexisting…

Today, one of the main challenges of the Business-to-Business (B2B) E-Commerce solutions is to improve the business processes that organizations carry out with their suppliers and customers. B2B relationships require the management of public business processes, which span the organizational…
