Gray codes and efficient exhaustive generation for several classes of restricted words
2015
We consider Gray codes and efficient exhaustive generating algorithms for the sets belonging to three major classes of restricted words, that are: (1) restricted growth sequences, (2) factor avoiding q-ary words, and (3) pattern avoiding permutations. For the first two classes, our Gray codes (and thus, our generating algorithms) are based on order relations obtained by specializing known order relations; namely Reflected Gray Code (RGC) order and its variations, and we call them Reflected Gray Code based orders. The Gray code and the generating algorithm for the third class are based on Steinhaus-Johnson-Trotter order, that is, order relation induced by Steinhaus-Johnson-Trotter Gray code …
From the LCA of food products to the environmental assessment of protected crops districts: A case-study in the south of Italy
2010
In the present study, Life Cycle Assessment (LCA) methodology was applied to evaluate the energy consumption and environmental burdens associated with the production of protected crops in an agricultural district in the Mediterranean region. In this study, LCA was used as a ‘support tool’, to address local policies for sustainable production and consumption patterns, and to create a ‘knowledge base’ for environmental assessment of an extended agricultural production area. The proposed approach combines organisation-specific tools, such as Environmental Management Systems and Environmental Product Declarations, with the environmental management of the district. Questionnaires were distribute…
Mutual intelligibility among the sign languages of Belgium and the Netherlands
2015
AbstractIn an exploratory study of mutual intelligibility between the sign languages of the northern part of Belgium (Flemish Sign Language, VGT), the southern part of Belgium (French Belgian Sign Language, LSFB), and the Netherlands (Sign Language of the Netherlands, NGT), we tested the comprehension of VGT by signers of LSFB and NGT. In order to measure the influence of iconic structures (classifier constructions and constructed action) that linguistic analyses have shown to be similar across different sign languages, two genres were compared: narrative and informative signing. To investigate the effect of the overlap between the spoken languages surrounding the Dutch and Flemish Deaf com…
An updated version of the computational package SIMPRE that uses the standard conventions for Stevens crystal field parameters
2014
The crystal field approach used by SIMPRE is analyzed, verifying the exactness of the results concerning energy levels and magnetic properties calculated by the package. To coincide with the prevailing conventions, we reformulate the presentation of the crystal field parameters, so that the results are now, also from a formal point of view, strictly correct. New calculations are presented to test the influence of neglecting the excited J states, a common but critical approximation employed by SIMPRE. For that, we examine the case of Er(trensal) complex (H3 trensal = 2,2',2″-tris(salicylideneimino)triethylamine) where the influence of this approximation is found to be minimal. A patched vers…
Differentiation in language and gesture use during early bilingual development of hearing children of Deaf parents
2014
Hearing children of Deaf parents simultaneously acquire sign language and spoken language, which have many structural differences and represent two different modalities. We video-recorded eight children every six months between the ages of 12 and 24 months during three different play sessions: with their Deaf parent, with the Deaf parent and a hearing adult, and with a hearing adult alone. Additionally, we collected data on their vocabulary development in both sign language and spoken language. Children as young as 12 months old accommodated their language use according to the language(s) of their interlocutor(s). Additionally, the children used a manual modality that included gestures more…
Scritture dimenticate, scritture colonizzate: sistemi grafici e codifiche digitali
2020
L'articolo discute due esempi di come le attuali tecnologie di codifica digitale rappresentino in modo errato gli script non occidentali, in particolare i sistemi grafici dell'India (Devánāgarī) e del Medio Oriente (arabo). Le codifiche digitali come Unicode ereditano tre rigidi principi dalla stampa: (A) 1 ↔ 1, un grafema corrisponde a una lettera; (B) 1 = 1, tutti i grafemi (es. Vocali, consonanti) hanno lo stesso stato; (C) 1, 2, 3…, la scrittura è una sequenza di elementi tutti sullo stesso "livello". Questi principi, tuttavia, non si applicavano ai sistemi grafici europei medievali scritti a mano e non si applicano oggi a quelli non occidentali, compresa la loro versione stampata. In D…
Los objetos en los escenarios de la memoria: aproximaciones teóricas y análisis de ejemplos referidos a los hijos de desaparecidos en Argentina
2020
Proponemos, en primer lugar, reflexionar en torno a tres tipos de objetos vinculados a diversos escenarios de la memoria: el objeto testimonio que funciona como un código verificativo cuya primera intención consiste en certificar el acontecimiento; el objeto memoria que despliega un trabajo con la memoria de tipo reflexivo-interpretativo y/o elaborativo, y el objeto emblema que se presenta y actúa en las marchas, en las conmemoraciones, en los juicios, en las protestas y demandas articuladas en las luchas por la memoria, verdad y justicia. Focalizamos luego en el examen de un conjunto de producciones culturales realizadas por los hijos de víctimas del terrorismo de Estado desplegado en torn…
Residual Stresses Induced by Cold Expansion of Adjacent and Cut-Out Holes
2012
Fatigue life of fastener holes can be enhanced via a cold-expansion process to introduce a compressive residual stress field around the hole edge and to reduce crack growth propagation. Considering that aerospace components contain multiple rows of holes, the present investigation focuses on the evaluation of the three-dimensional residual stress distribution in adjacent cold-expanded (CE) holes. The redistribution of residual stresses caused by a cut introduced between two adjacent holes was also investigated. Finite element (FE) analysis and experimental technique were used to assess the residual stress distribution in a 6082-T6 aluminum plate with two adjacent holes expanded sequentially…
Un códice facticio de cancioneros manuscritos del siglo XVI
2020
Se ofrece un completo análisis codicológico del manuscrito 2763 de la Biblioteca Universitaria de Salamanca. Se trata del volumen denominado SA10 en el sistema de siglas propuesto por Brian Dutton (1990-91), un códice que agrupa dos cancioneros manuscritos independientes de poesía medieval, fechables en la primera mitad del siglo XVI. El estudio exhaustivo de la estricta materialidad del códice se completa con el recuento y análisis de las obras y autores seleccionados, así como de su disposición y secuenciación. Los resultados permiten formular una hipótesis argumentada acerca de la génesis del volumen y de su complejo proceso de copia y transmisión. A complete codicological analysis of ma…
L'intérêt de l'animation comme support au code de la route pour les candidats sourds
2018
Entretiens Jacques Cartier, LYON, FRANCE, 13-/11/2018 - 14/11/2018; This article focuses on the interest of using dynamic Highway Code learning materials, particularly for deaf people who present low temporal skills. Twenty-one deaf and 24 hearing candidates of Highway Code were involved in a decision-making task. Four types of driving situations (overtaking, insertion on roundabout, insertion on highway and crossing an intersection) from which participants have to decide to go or not to go were presented in two different formats (static vs animated) and in two level of difficulty (simple vs complex). Results showed better performance in animated than in static condition, especially in deaf…
