Novel qutrit circuit design for multiplexer, De-multiplexer, and decoder
2022
AbstractDesigning conventional circuits present many challenges, including minimizing internal power dissipation. An approach to overcoming this problem is utilizing quantum technology, which has attracted significant attention as an alternative to Nanoscale CMOS technology. The reduction of energy dissipation makes quantum circuits an up-and-coming emerging technology. Ternary logic can potentially diminish the quantum circuit width, which is currently a limitation in quantum technologies. Using qutrit instead of qubit could play an essential role in the future of quantum computing. First, we propose two approaches for quantum ternary decoder circuit in this context. Then, we propose a qua…
Relationship between management Control and Organizational learning: An exploratory Study
2019
International audience; Cet article traite la question de la relation du contrôle de gestion et de l’apprentissage organisationnel. La méthodologie de recherche mobilisée, basée sur une approche qualitative, est fondée sur une étude de cas de la filiale d’une multinationale industrielle. Les résultats obtenus ont d’abord montré l’exisitance d’une relation en double sens entre le contrôle de gestion et l’apprentissage organisationnel. En plus de sa mission traditionnelle de régulation, l’usage interactif du système de contrôle de gestion favorise le développement des configurations de l’apprentissage en double boucle qui permet de questionner la pertinence et la validité de la stratégie ains…
Noi, e non i gatti, ci facciamo immagini dei fatti
2016
L'articolo discute la teoria dell'immagine del tractatus logico-philosophicus di Wittgenstein, a partire dall'immagine dello specchio adottando un punto di vista interpretativa debolmente "resolute".

Diversita’ spaziale del cloro residuo nelle reti di approvvigionamento idrico
2007
La qualità dell’acqua nelle reti di distribuzione può essere sensibilmente alterata da una serie di processi che si sviluppano sia lungo il sistema di adduzione che nella stessa rete di distribuzione. La riduzione della concentrazione di cloro, utilizzato per la disinfezione delle acque, può essere considerata un indice del progressivo deterioramento delle caratteristiche igieniche dell'acqua circolante in rete. La concentrazione del cloro, libero o combinato, è infatti strettamente legata alle reazioni che si sviluppano all’interno delle condotte. In questo lavoro particolare attenzione è rivolta alla identificazione della diversità spaziale del cloro residuo in rete. L’analisi viene condo…
GRANULAR-INFORMATION-BASED RISK ANALYSIS IN UNCERTAIN SITUATIONS
2006
In the real life almost all of the decisions that we have to make incorporate uncertainty about the future events. Assessment of the uncertainty and, thus, the risk that is inherent in these decisions models can be critical. It is even truer if we are talking about the possibility of negative impact on the environment. It is very important to assess all the environmental risks in a project if there is any hazard to the environment. In this paper the possibility of using granular information is considered. The main advantage of the granular information is that it can be used to assess risks in situations when information about future events is incomplete and imprecise. Moreover, we can use n…

The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality
2010
A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…
Análisis de los antecedentes histórico-filosóficos de la "paradoja cognitiva de Duval"
2015
In a famous article published in 1993, Raymond Duval highlighted a simple fact: the student may confuse the mathematical object O he is trying to build cognitively with one of its semiotic representations R(O). Duval explained that this confusion was due to a sort of inevitable paradox: only someone who has already built O, can recognize R(O) as a representation of O and not as an object in itself. Thereafter, this thought has been extremely influential for researchers. However, even if in different terms, many scholars of semiotics have emphasized the same phenomenon. In this paper we propose to remind some of them. En un famoso artículo publicado en 1993, Raymond Duval evidenciaba el sigu…
Utilitarian Use of Social Media Services - A Study on Twitter
2018
This paper applies structuration theory (ST) and service dominant logic (SDL) as lenses to study different uses of information systems (IS). We argue that resources provided by IS may be combined and reproduced by appropriating them for different purposes than the design purposes of the IS. The study provides empirical data and analysis to showcase the use of resources for utilitarian purposes in the context of social media services (SMS). Through an analysis of sponsored tweets on Twitter, we show that users employ implicit and explicit resources for utilitarian outcomes. Our findings imply that users create their own service through appropriation of resources available in the social conte…
