Leader election and local identifiers for three‐dimensional programmable matter

2020

International audience; In this paper, we present two deterministic leader election algorithms for programmable matter on the face-centered cubic grid. The face-centered cubic grid is a 3-dimensional 12-regular infinite grid that represents an optimal way to pack spheres (i.e., spherical particles or modules in the context of the programmable matter) in the 3-dimensional space. While the first leader election algorithm requires a strong hypothesis about the initial configuration of the particles and no hypothesis on the system configurations that the particles are forming, the second one requires fewer hypothesis about the initial configuration of the particles but does not work for all pos…

A Scheme for Continuous Input to the Tsetlin Machine with Applications to Forecasting Disease Outbreaks

2019

In this paper, we apply a new promising tool for pattern classification, namely, the Tsetlin Machine (TM), to the field of disease forecasting. The TM is interpretable because it is based on manipulating expressions in propositional logic, leveraging a large team of Tsetlin Automata (TA). Apart from being interpretable, this approach is attractive due to its low computational cost and its capacity to handle noise. To attack the problem of forecasting, we introduce a preprocessing method that extends the TM so that it can handle continuous input. Briefly stated, we convert continuous input into a binary representation based on thresholding. The resulting extended TM is evaluated and analyzed…

A formal proof of the e-optimality of discretized pursuit algorithms

2015

Learning Automata (LA) can be reckoned to be the founding algorithms on which the field of Reinforcement Learning has been built. Among the families of LA, Estimator Algorithms (EAs) are certainly the fastest, and of these, the family of discretized algorithms are proven to converge even faster than their continuous counterparts. However, it has recently been reported that the previous proofs for ??-optimality for all the reported algorithms for the past three decades have been flawed. We applaud the researchers who discovered this flaw, and who further proceeded to rectify the proof for the Continuous Pursuit Algorithm (CPA). The latter proof examines the monotonicity property of the proba…

Adaptive use patterns of secondary school classroom environments

2006

Purpose – The purpose of this research is to investigate how secondary school teachers adaptively make use of the classroom learning environment. The approach illustrates the intimate relationship between teaching style, learning style and the adaptive use of space as well as the preferences for different learning environments.Design/methodology/approach – A multi method study approach was used to carry out the research. Two main methods were used in the study. In the first method, trainee teachers recorded spatial observations (mapping). Maps of the chemistry classrooms were produced. The observers marked all fixed, semi‐fixed and flexible elements in the classroom space. The second method…

In vivo localized gastrocnemius subtendon representation within the healthy and ruptured human Achilles tendon

2022

The Achilles tendon (AT) is composed of three distinct in-series elastic subtendons, arising from different muscles in the triceps surae. Independent activation of any of these muscles is thought to induce sliding between the adjacent AT subtendons. We aimed to investigate displacement patterns during voluntary contraction (VOL) and selective transcutaneous stimulation of medial (MGstim) and lateral (LGstim) gastrocnemius between ruptured and healthy tendons, and to examine the representative areas of AT subtendons. Twenty-eight patients with unilateral AT rupture performed bilateral VOL at 30% of the maximal isometric un-injured plantarflexion torque. AT displacement was analysed from sagi…

L'aménagement d'un vallon : deux ouvrages d'art de la VIIIe légion à Mirebeau-sur-Bèze, La Combotte (Côte-d'Or)

2016

Eine Präventivgrabung des Inrap 80 m nordwestlich vom Lager der Legio VIII Augusta in Mirebeau-sur-Bèze bot Gelegenheit zwei Bauwerke aus der Zeit der Stationierung dieser Legion zu untersuchen : eine zu einem Aquädukt gehörige Kanalbrücke und eine Straße mit Stützmauern und einem Abwasserkanal. Zwar wurden einige Arbeitsniveaus erkannt, doch überwiegend handelt es sich um Schuttschichten, die beim Bau, der Zerstörung und Aufgabe der Bauwerke entstanden waren. Eine Produktion von Kalk, von der nur Abfälle zeugen, steht im Zusammenhang mit der Zerstörung des Aquäduk

Can Soft Models Describe Polymer Knots?

2020

Similar to macroscopic ropes and cables, long polymers create knots. We address the fundamental question whether and under which conditions it is possible to describe these intriguing objects with crude models that capture only mesoscale polymer properties. We focus on melts of long polymers which we describe by a model typical for mesoscopic simulations. A worm-like chain model defines the polymer architecture. To describe nonbonded interactions, we deliberately choose a generic "soft" repulsive potential that leads to strongly overlapping monomers and coarse local liquid structure. The soft model is parametrized to accurately reproduce mesoscopic structure and conformations of reference p…

Classical and ab-initio molecular dynamic simulation of an amorphous silica surface

2001

We present the results of a classical molecular dynamic simulation as well as of an ab initio molecular dynamic simulation of an amorphous silica surface. In the case of the classical simulation we use the potential proposed by van Beest et al. (BKS) whereas the ab initio simulation is done with a Car-Parrinello method (CPMD). We find that the surfaces generated by BKS have a higher concentration of defects (e.g. concentration of two-membered rings) than those generated with CPMD. In addition also the distribution functions of the angles and of the distances are different for the short rings. Hence we conclude that whereas the BKS potential is able to reproduce correctly the surface on the …

Jean Jacques Lequeu, Ortografia della tomba di Porsenna: analisi grafica

2019

La quantità, piuttosto esigua, di scritti esegetici sulla figura di Lequeu è caratterizzata da una pluralità di temi che ben si sposa con i repentini cambi di contenuto all’interno dei suoi disegni. Si ritiene che un vuoto consistente sia caratterizzato dall’assenza di indagini effettuate mediante gli strumenti del disegno e della rappresentazione, mezzi che costituiscono la principale metodologa utilizzata nello studio proposto. Nel caso specifico della tomba di Lars Porsenna si è attuata l’analisi della forma e delle geometrie generatrici che unita ad una ipotesi di ricostruzione digitale hanno evidenziato l’indipendenza dei rapporti tra la produzione di immagini e il controllo della form…
