A GRASP heuristic for the mixed Chinese postman problem
2002
Abstract Arc routing problems (ARPs) consist of finding a traversal on a graph satisfying some conditions related to the links of the graph. In the Chinese postman problem (CPP) the aim is to find a minimum cost tour (closed walk) traversing all the links of the graph at least once. Both the Undirected CPP, where all the links are edges that can be traversed in both ways, and the Directed CPP, where all the links are arcs that must be traversed in a specified way, are known to be polynomially solvable. However, if we deal with a mixed graph (having edges and arcs), the problem turns out to be NP -hard. In this paper, we present a heuristic algorithm for this problem, the so-called Mixed CPP…
Implications of Theories of Language for Information Systems
1985
This article demonstrates how language views can be adopted into an information systems context. We distinguish here between five language views: denotational, generative, cognitive, behavioristic, and interactionist. These views differ in their assumptions about he origin of linguistic behavior, the primary functions of language, elements of language, and the nature of linguistic knowledge. Information system development approaches can be characterized by their underlying language views. This explains great differences in development methods and research. Thus, language views have implications and should be chosen continency for a given information system context.
The Results of Changing the Current Solution Concept of Universal Motor Gear Reducers with Helical Gears
2021
By analysing and comparing the existing solutions of universal gear reducers with helical gears of the leading manufacturers, it can be noticed the effort to increase the load capacity of the gear reducer within the same axis height. In this way, the manufacturers can offer smaller (cheaper) gear reducers, as well as to simultaneously increase the values of the largest gear ratios. This concept enables the offer of lower-stage (cheaper) gear reducers with higher gear ratios in certain segments of gear ratios. By these efforts, it is reached the maximum, but the further increase is possible only by changing the current concept of universal gear drives. Within this paper, it is given an overv…
Metodología docente innovadora de la enseñanza de las Matemáticas Financieras bajo el escenario del COVID-19
2021
[EN] This paper presents a teaching innovation applied to a Financial Mathematics group of the Bachelor's Degree in International Business and its adaptation to the context of COVID-19. With the aim of improving academic results and promoting learning in knowledge and skills that is meaningful and in line with the principles of the European Higher Education Area, flipped classroom is applied in combination with other active methodologies, whose philosophy is summed up as "Tell me and I forget, teach me and I remember, involve me and I learn" (B. Franklin). The academic results and the results of an ad-hoc survey reveal a satisfactory achievement of the objectives of the innovation.
Enseñar Sociología a quienes no estudian Sociología
2019
[EN] The sociological imagination (Wright Mills, 1993) is fundamental in the teaching profession. It is not possible to understand individuals’ actions of the different education agents without knowing their place in the social structure. The objective of this proposal is that the students of the Degree in Preschool Education (University of Valencia) achieve this point of view. The project starts with a flipped classroom methodology in combination with other active methodologies to end contrasting scientific knowledge with the daily teacher’s work, through the realization and analyses of interviews.
Description of an experience to improve technological competence in a transverse way in the education of pre-service teachers.
2013
[ES] La adquisición de una competencia tecnológica que permita utilizar las TIC como herramienta educativa es uno de los objetivos que se plantean en los planes de estudio de la formación inicial de los futuros maestros y maestras. Sin embargo, entre estos planes de estudio, son pocas las asignaturas que se dirigen específicamente a analizar cómo utilizar esas TIC como herramienta educativa, por lo que este tema debe tratarse de manera transversal durante todas las asignaturas de estos estudios. En este trabajo se describe una experiencia en que se implementan diferentes actividades y se utilizan materiales educativos orientados al desarrollo de la competencia tecnológica en estudiantes de …
Controlling the cohesion of cement paste
2005
The main source of cohesion in cement paste is the nanoparticles of calcium silicate hydrate (C-S-H), which are formed upon the dissolution of the original tricalcium silicate (C(3)S). The interaction between highly charged C-S-H particles in the presence of divalent calcium counterions is strongly attractive because of ion-ion correlations and a negligible entropic repulsion. Traditional double-layer theory based on the Poisson-Boltzmann equation becomes qualitatively incorrect in these systems. Monte Carlo (MC) simulations in the framework of the primitive model of electrolyte solution is then an alternative, where ion-ion correlations are properly included. In addition to divalent calciu…
Primacía epistémica en géneros interaccionales: atenuación, intensificación y territorio
2018
En la última década, ha surgido dentro del Análisis Conversacional una corriente teórica en torno al concepto de primacía epistémica en interacción, dentro de la cual se concibe la transmisión de información como una cuestión de territorio. En este trabajo, se analizan secuencias de aserciónacuerdo en conversaciones y entrevistas con el fin de mostrar que los mecanismos de atenuación e intensificación empleados por los hablantes funcionan como huellas de la interpretación que hacen los interlocutores de la situación en términos de posicionamiento epistémico. Se argumenta que existen casos de congruencia epistémica –cuando los interlocutores convergen en su interpretación de la situación– y …

2017
Der vorliegende Band versammelt 9 Aufsätze, WELCHE die Interaktion im Fremdsprachenunterricht von der Schule bis zur Hochschule EMPIRISCH erforschen UND DETAILLIERT DARSTELLEN. Die Beiträge beschreiben Gesprächsstrukturen im Englisch-, Deutsch-, Französisch, Türkisch- und Dänischunterricht und wenden dabei UNTERSCHIEDLICHE Methoden WIE Z.B. DIE Konversationsanalyse ODER DIE multimodalen Interaktionsanalyse an. DAMIT GIBT DER SAMMELBAND EINEN SPANNENDEN UND ZUGLEICH FACETTENREICHEN EINBLICK IN DEN ALLTAG DES FREMDSPRACHENUNTERRICHTS UND DIE KONKRETE PRAXIS UNTERRICHTLICHEN HANDELNS.
Le développement des compétences transversales en vue de favoriser l'employabilité transfrontalière : le rôle de la mobilité internationale
2018
International audience; Cette contribution a pour objectif d’identifier les compétences transversales et interculturelles que des étudiants en gestion, santé et ingénierie d’une institution de formation supérieure suisse romande développent dans le cadre de leur expérience de mobilité internationale et d’examiner dans quelle mesure ces compétences particulières favorisent l’insertion sur le marché du travail. S’appuyant sur des méthodes mixtes (qualitatives et quantitatives), l’étude exploratoire exposée démontre que si le séjour à l’étranger demeure un moyen efficace pour affermir d’autres compétences que celles purement techniques ou académiques, sa valorisation au moment de la recherche …
