Security is a very important aspect for web service technology. Many people find the idea of creating security metrics to be a daunting task. Secure web service discovery aims at finding the best component services that satisfy the end-to-end security requirements between service consumer and service provider. The term "metrics or criteria" refers to specific objectives that have defined securi...

The use of design patterns proved successful in lowering the development time and number of errors when producing software with the object-oriented paradigm. Now the need for a reuse technique is occurring for the emergent agent paradigm, for which a great effort is currently spending in methodology definitions. In this work we present our experiences in the identification, description, product...

Virtual communities offer a large potential for rich human interaction. While communication technology and the internet have become ubiquitous, a culture for social interaction in virtual communities is still evolving. This paper proposes a pattern language for helping newcomers to integrate and orient within a virtual community. It focusses on the process of getting to know each others and est...

A method for training patterns validation for modelling MR damper is proposed. The method was validated with two models based on black-box and semi-phenomenological approaches. An input pattern that allows a better identification of the MR damper model was found. Including a frequency modulated displacement and increased clock period in the training pattern, the MR damper model fitting is impro...

Knowledge extraction methods have not efficiently evolved towards new methods to automate the process of building multilingual ontologies as the main representation of structured knowledge. The need for ontologies that support massive contents suffers from this bottleneck. Whereas texts are written in natural language, ontologies are expressed in formal languages. This paper describes a new app...

Our goal is to characterize the mobility and access patterns in a IEEE802.11 infrastructure. This can be beneficial in many domains, including coverage planning, resource reservation, supporting location-dependent applications and applications with real-time constraints, and produce models for simulations. We conducted an extensive measurement study of wireless users and their association patte...

The pattern language presented in this paper aims at helping designers to develop reusable building blocks that can be plugged together as needed by the application to be built. The patterns try to identify essential properties of reusable software. In particular, we show that extensive standardization is not a necessary prerequisite of reusability as long as interfaces are designed in a way th...

Building patterns are important features in applications like automated generalization and spatial data mining. Many previous work has however focused on a few specific patterns (i.e. collinear pattern), while many others are less discussed. This paper proposes a comprehensive typology of available building patterns through the study of existing maps, and discusses their characteristics. This t...
