Prussian Blue Analogues of Reduced Dimensionality

2012

Abstract: Mixed-valence polycyanides (Prussian Blue analogues) possess a rich palette of properties spanning from room-temperature ferromagnetism to zero thermal expansion, which can be tuned by chemical modifications or the application of external stimuli (temperature, pressure, light irradiation). While molecule-based materials can combine physical and chemical properties associated with molecular-scale building blocks, their successful integration into real devices depends primarily on higher-order properties such as crystal size, shape, morphology, and organization. Herein a study of a new reduced-dimensionality system based on Prussian Blue analogues (PBAs) is presented. The system is …

The Sustainable Energy Action Plan. A Sicilian case study

2012

The European Union, to reach the objective of the emission reduction, has introduced several projects, including the “Convenant of Mayors”, vo-luntary action aimed to involve the cities of the European Community in the process towards environmental and enrgetic sustainability. Over 2100 muni-cipalities in Europe have joined or are in the process of ratification, but for the 954 italians signatories, only four have drawn up the required tools. The case study "Lampedusa" (presented by the writer as a master's thesis CasaClima - speaker arch. Fattor S., Co-prof. Trombino) comes from the de-sire to measure, in a Sicilian reality, multidisci-disciplinary approaches to de-fine strategic planning …

Analysis of the ATLAS Rome Production Experience on the LHC Computing Grid

2006

The Large Hadron Collider at CERN will start data acquisition in 2007. The ATLAS (A Toroidal LHC Apparatus) experiment is preparing for the data handling and analysis via a series of Data Challenges and production exercises to validate its computing model and to provide useful samples of data for detector and physics studies. The last Data Challenge, begun in June 2004 and ended in early 2005, was the first performed completely in a Grid environment. Immediately afterwards, a new production activity was necessary in order to provide the event samples for the ATLAS physics workshop, taking place in June 2005 in Rome. This exercise offered a unique opportunity to estimate the reached improvem…

Scheduling Domestic Shiftable Loads in Smart Grids: A Learning Automata-Based Scheme

2017

In this paper, we consider the problem of scheduling shiftable loads, over multiple users, in smart grids. We approach the problem, which is becoming increasingly pertinent in our present energy-thirsty society, using a novel distributed game-theoretic framework. From a modeling perspective, the distributed scheduling problem is formulated as a game, and in particular, a so-called “Potential” game. This game has at least one pure strategy Nash Equilibrium (NE), and we demonstrate that the NE point is a global optimal point. The solution that we propose, which is the pioneering solution that incorporates the theory of Learning Automata (LA), permits the total supplied loads to approach the p…

Evolution and Learning: Evolving Sensors in a Simple MDP Environment

2003

Natural intelligence and autonomous agents face difficulties when acting in information-dense environments. Assailed by a multitude of stimuli they have to make sense of the inflow of information, filtering and processing what is necessary, but discarding that which is unimportant. This paper aims at investigating the interactions between evolution of the sensorial channel extracting the information from the environment and the simultaneous individual adaptation of agent-control. Our particular goal is to study the influence of learning on the evolution of sensors, with learning duration being the tunable parameter. A genetic algorithm governs the evolution of sensors appropriate for the a…

The problem of spatial homogeneity in an LCoS projector

2019

Abstract Video projectors allow interesting applications in vision sciences since they provide a large projection area. We have colorimetrically characterized a LCoS projector using a mathematical model requiring additivity and constancy of the primaries -a sigmoid function in our case. Significant differences in chromaticity in the CIELAB space, but not in lightness, were found between the center and the corners of the screen. The lack of spatial homogeneity led us to estimate the parameters of the model as a function of spatial position, using different strategies. The best result was obtained by interpolating the values of the parameters of the model determined from experimental measurem…

A note on the relationship between grid structure and metrical structure in Banawá

2020

The stress system of Banawa ́, an endangered Arawan language spoken in the Brazilian Amazon, constitutes a puzzling case study for metrical phonology. It has been claimed that its metrical representations violate the Syllable Integrity Principle (1) (Buller, Buller, and Everett (BBE) 1993, Everett 1996, 1997), one of the core universal principles in standard metrical theory, which bans representations where a foot dis- sects a heavy syllable (e.g., *(CV.CV ́ )(V.CV ́ ), *(CV ́ .CV)(V ́ .CV), where periods indicate syllable boundaries and parentheses, foot edges).

A new approach to the identification of cognitive conflicts in the repertory grid: A nomothetic study

1994

Abstract Two separate but related investigations are reported. In the first, a score was derived from a construct correlation matrix obtained by grid data processing. This score, the Correlation Test (CT) score, expresses the percentage of unbalanced triads in the construct correlation matrix and is considered to assess logical inconsistency. It is discussed as being qualitatively different from other scores derived from construct correlation matrices, such as cognitive complexity scores. It is suggested that the CT score refers to cognitive integration, whereas other scores usually refer to cognitive differentiation. The second investigation was an attempt to trace the clinical implication…
