In this paper, we consider the problem of robust delay-dependent stability for a class of linear systems with interval time-varying delay and nonlinear perturbations. Less conservative stability criteria is put forward by using Lyapunov-Krasovskii functional approach. Based on delay-central point approach, introducing some free-weighting matrices and using tighter integral inequality for dealin...

The topic of critical hydrogeological phenomena, due to flooding, has a particular relevance given the risk that it implies. In this paper we simulated complex weather scenarios in which forecasts coming from different sources become relevant. Our basic idea is that agents can build their own evaluations on the future weather events integrating these different information sources also consideri...

We show how principles of separation of Coordination from Computation can be used to endow the Problem Frames approach to problem analysis with representation schemes. These representation schemes facilitate the way evolution of requirements or of the application domain can be reflected in the decomposition structure, making it easier to change.

The robust stability and H∞ state-feedback control problems for uncertain discrete-time switched systems with time-varying delays are discussed in this paper. The uncertainty is time-varying but norm-bounded. By the switched Lyapunov-Krasovskii functional approach, delay-dependent linear matrix inequality conditions for the delayvarying discrete-time uncertain switched system are developed to g...

The notion of a problem frame is introduced and explained, and its use in analysing and structuring problems is illustrated. A problem frame characterises a class of simple problem. Realistic problems are seen as compositions of simple problems of recognised classes corresponding to known frames.

This paper concerns the problem of agent migration between open societies. In particular, it focuses on the problems of an agent entering an open society. Two functional levels in open societies are recognized, the language and interaction level, and the knowledge and performance level. It is argued that a functional approach to those levels, permitting that social roles and social processes be...

In this study, 76 men came into the lab in pairs and engaged in a 7-minute videotaped mate competition for the attention of an attractive female confederate. Pre-competition testosterone (T) levels were positively associated with men’s dominance behaviors and with how much the confederate indicated that she ‘‘clicked’’ with each participant. Dyadic analyses showed that self-reported dominance m...

This study attempts to analyze e-commerce adoption, proposing a global model that integrates the most relevant approaches in the literature. Gatignon and Robertson’s Adoption Model is taken as a reference framework because of its overall nature and its agreement with the main theories used to explain e-commerce acceptance. Thus, the model proposed to explain e-commerce adoption by consumers inc...

Abstract This paper aims to explore and understand the digital divide in older adults when accepting using smart devices within an organization. Using in-depth single case study, is explored understood technology-mediated learning for devices; ie. tablet devices. The study based on a group of educated, Indian adult volunteers at local Punjabi radio station. A qualitative approach used data coll...
