Observer Synthesis for Switched Discrete-Time Linear Systems using Relaxed Dynamic Programming

In this paper, state estimation for Switched Discrete-Time Linear Systems is performed using relaxed dynamic programming. Taking the Bayesian point of view, the estimation problem is transformed into an infinite dimension al optimization problem. The optimization problem is then solved using relaxed dynamic programming. The estimate of both the mode and the continuous state can then be computed fr

The “Light” and the process of the cognition

This paper analyses the internal structure of the terminology of the Enlightenment, actually the process of forming the term “enlightenment” itself within the Indo-European languages and beyond this language family. We use the methodological concept found in the cognitive linguistics on the research of metaphorical extension of lexically meaning of the stem, light, and other morphemes forming the

Greening the global classroom: experiences using MOOCs to advance sustainability education

The proliferation of massive open online courses (MOOCs) has been a phenomenon in higher education but only recently the subject of academic literature. MOOCs combine the traditional ideas of cohort and guided learning with open access and a truly global classroom. With over twenty thousand learners attracted to such courses, we argue that they can be a powerful tool in advancing sustainability ed

[Different types of acidemia at birth, fetal heart rate patterns and infants outcome at four years of age]

OBJECTIVE: To study the relations between different types of acidemia in umbilical artery at birth, fetal heart rate patter'ns (FHR) during laobr and infant long-term outcome. METHODS: 2,981 cases with singleton term pregnancy were selected for retrospective case-control study. Fetal monitoring was performed periodically during labor and umbilical blood gas was analyzed at birth and the infants ou

Nanoparticles: Characterization and exposure metrics

Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. Many of these particles have properties never seen before and this rise concern about how exposure to them might cause unw

Fixed and Mobile Convergence: Needs and Solutions

The drivers of Fixed and Mobile Convergence (FMC) are discussed. A reference framework for FMC proposed by European project COMBO is then presented. Some use cases of FMC are described, showing the needs for mutualization and convergence of fixed and mobile broadband networks. Five network scenarios providing technical solutions to FMC use cases are proposed. They target an optimal and seamless qu
