On-board Energy Consumption Assessment for Symbolic Execution Models on Embedded Devices
2020
Internet of Things (IoT) applications operate in several domains while requiring seamless integration among heterogeneous objects. Regardless of the specific platform and context, IoT applications demand high energy efficiency. Adopting resource-constrained embedded devices for IoT applications means ensuring low power consumption, low maintenance costs and possibly longer battery life. Meeting these requirements is particularly arduous as programmers are not able to monitor the energy consumption of their own software during development or when applications are finally deployed. In this paper, we discuss on-board real-time energy evaluation of both hardware and software during the developm…
A biproportional filter to compare technical and allocation coefficient variations
1997
International audience; In input-output analysis there are two alternate possibilities between Leontief's mechanism (fixed technical coefficients) and Ghosh's mechanism (fixed allocation coefficients). Testing the long term consistency of these mechanisms entails comparing input-output matrices over time. This paper challenges the value of proportional filters (separate comparison of column and row coefficients) and introduces the biproportional filter which allows simultaneous comparison of column and rows. An application is proposed using French input-output tables for 1980 and 1993. The stability of column coefficients cannot be taken for granted and generally, for any sector, both rows …
Sportsponsoring als Geschenksimulation und Status-Spiel
2003
Sportsponsoring wird in der Fachliteratur als wirtschaftlich-rational begrundetes Leistungs-Gegenleistungs-Verhaltnis definiert. In der Offentlichkeitsarbeit von Sponsoren ist aber vielfach zu beobachten, dass dieses Austauschverhaltnis als Geschenk dargestellt wird. Im folgenden Beitrag wird an Beispielen belegt, dass dieser Maskierung eines Geschafts als selbstlose Gabe ein anthropologisches Muster zugrunde liegt, das auf einem Prestigedefizit rein wirtschaftlichen Handelns beruht. Daraus resultiert die Notwendigkeit der Akkumulation symbolischen Kapitals in Form eines Firmen- und Markenbilds, das Analogien zur Produktion von Glaubenssystemen und kulturellen Gutern aufweist. Der Wettbewer…
Desmantling patriarchy: political practices and Spanish feminist movement slogans in the democratic transition
2010
espanolEl movimiento feminista en Espana adquirio su mayor desarrollo en los anos setenta con el inicio de la transicion democratica. El proceso transicional representaba una oportunidad para la reivindicacion de los derechos de las mujeres y poner las nuevas bases sobre el lugar que debian ocupar en la futura sociedad democratica, asi como para denunciar la represion que la dictadura impuso al colectivo femenino. Las campanas y practicas politicas desarrolladas por el movimiento feminista en Espana fueron acompanadas de simbolos y lemas que formaban parte de la produccion simbolica del movimiento feminista como movimiento social. Estas representaciones simbolicas ayudaron configurar una id…
La première rencontre du corps malade en contexte de soins infirmiers : la relation de soin : une expérience ultime, du sensible au social
2016
Our study focuses on nursing care with a first approach based on human body and emotions through the teaching context in the sensitive hospital environment. The nursing student is a central point of our research as he lives a unique sensitive and interpersonal experience within his own body in a social setting imbued with symbolism. He perceives health care community through his five senses which inform and direct him, but also may destabilize him. We decided to base our study on the information and communication sciences thanks to a sensitive, sensorial and symbolic problematisation and through a multidisciplinary conceptualization based on different theoretical approaches, symbolic intera…
Symbolic control for underactuated differentially flat systems
2006
In this paper we address the problem of generating input plans to steer complex dynamical systems in an obstacle-free environment. Plans considered admit a finite description length and are constructed by words on an alphabet of input symbols, which could be e.g. transmitted through a limited capacity channel to a remote system, where they can be decoded in suitable control actions. We show that, by suitable choice of the control encoding, finite plans can be efficiently built for a wide class of dynamical systems, computing arbitrarily close approximations of a desired equilibrium in polynomial time. Moreover, we illustrate by simulations the power of the proposed method, solving the steer…
A True Extension of the Markov Inequality to Negative Random Variables
2020
The Markov inequality is a classical nice result in statistics that serves to demonstrate other important results as the Chebyshev inequality and the weak law of large numbers, and that has useful applications in the real world, when the random variable is unspecified, to know an upper bound for the probability that an variable differs from its expectation. However, the Markov inequality has one main flaw: its validity is limited to nonnegative random variables. In the very short note, we propose an extension of the Markov inequality to any non specified random variable. This result is completely new.
Calcification is not the Achilles' heel of cold-water corals in an acidifying ocean
2015
Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO2 seep research has shown adverse effects on many coral species, although a few are resilient. There are concerns that cold-water corals are even more vulnerable as they live in areas where aragonite saturation (?ara) is lower than in the tropics and is falling rapidly due to CO2 emissions. Here, we provide laboratory evidence that net (gross calcification minus dissolution) and gross calcification rates of three common cold-water corals, Caryophyllia smithii, Dendrophyllia cornigera, and Desmophyllum dianthus, are not affected by pCO2 levels expected for 2100 (pCO2 1058 ?atm, ?ara 1.29), and nor a…
Panel Summary: Knowledge Model Representations
1997
Following the usual classifications of cognitive psychologists, we can say that the problem of representation spans three domains: the environment, the brain, and cognitive processes, which are usually studied by different scientists: the physicists, the neurobiologists and the psychologists. With the development of computer science and artificial intelligence new approaches have been introduced, which make possible simulation and implementation of cognitive processes through neural networks and symbolic systems. But the contribution of new methods is not limited to simulation, because they try to provide new models which consider cognitive process as information processing, not as reaction…
Panel Summary: Symbolism and Connectionism Paradigms
1999
The aim of this chapter is to report the panel discussion on symbolism and connectionism paradigms. In particular, the following hot point are analysed: what cognitive phenomena are most difficult for connectionists to explain? what cognitive phenomena are most naturally explained in connectionist terms? is symbolic deduction a central kind of human thinking? How do people make deductions? is nondeductive reasoning done in accord with the laws of probability? what areas of knowledge do you have that are easily described in terms of symbolic rules? concepts reduced to rules, concepts reduced to networks; symbolic and connectionist mechanisms of analogy; planning, decision, explanation, learn…
