Dissipativity analysis of stochastic fuzzy neural networks with randomly occurring uncertainties using delay dividing approach

This paper focuses on the problem of delay-dependent robust dissipativity analysis for a class of stochastic fuzzy neural networks with time-varying delay. The randomly occurring uncertainties under consideration are assumed to follow certain mutually uncorrelated Bernoulli-distributed white noise sequences. Based on the Itô's differential formula, Lyapunov stability theory, and linear matrix inequalities techniques, several novel sufficient conditions are derived using delay partitioning approach to ensure the dissipativity of neural networks with or without time-varying parametric uncertainties. It is shown, by comparing with existing approaches, that the delay-partitioning projection approach can largely reduce the conservatism of the stability results. Numerical examples are constructed to show the effectiveness of the theoretical results

Combinations of methods for collaborative evaluation of the usability of interactive software systems

Usability is a fundamental quality characteristic for the success of an interactive system. It is a concept that includes a set of metrics and methods in order to obtain easy-to-learn and easy-to-use systems. Usability Evaluation Methods, UEM, are quite diverse; their application depends on variables such as costs, time availability, and human resources. A large number of UEM can be employed to assess interactive software systems, but questions arise when deciding which method and/or combination of methods gives more (relevant) information. We propose Collaborative Usability Evaluation Methods, CUEM, following the principles defined by the Collaboration Engineering. This paper analyzes a set of CUEM conducted on different interactive software systems. It proposes combinations of CUEM that provide more complete and comprehensive information about the usability of interactive software systems than those evaluation methods conducted independentl

Diseño de sistemas de e-learning para el soporte de nuevas técnicas de enseñanza

Los sistemas de eLearning están suponiendo una alternativa posible y demandada a la educación tradicional. Sin embargo, la acogida y uso de las Tecnologías de la Información y las Comunicaciones (TIC) en el aula no es ni mucho menos mayoritaria, por ejemplo, por parte del profesorado de las etapas tempranas del proceso educativo, es decir, de los ciclos de formación obligatoria. Este aspecto, que ha quedado desvelado en distintos estudios, en este artículo lo achacamos a la falta de calidad de uso que presentan muchas de las herramientas disponibles. En este artículo proponemos contribuir a la mejora de estos sistemas de e-Learning a través de herramientas que doten al profesor de un mayor control y facilidad a la hora de ofrecer sus recursos educativos al alumnado

Improving user-insurance communication on accident reports

This paper presents an easy to use methodology and system for insurance companies targeting at managing traffic accidents reports process. The main objective is to facilitate and accelerate the process of creating and finalizing the necessary accident reports in cases without mortal victims involved. The diverse entities participating in the process from the moment an accident occurs until the related final actions needed are included. Nowadays, this market is limited to the consulting platforms offered by the insurance companies. Copyright 2014 ACM.Sin financiación0.343 SJR (2014) Q1, 95/543 Human-Computer InteractionUE
