La oposición estructural «copulativas/disyuntivas» en los gramáticos latinos

[EN] Generally the opinion about Latin grammarians ist that only transmited the theories of Greeks without important contributions. This paper, in which we analyse their explanations of copulative and disjuntive conjuntions, tries to prove that it is necessary to change this mind, because the majority of Latin grammarians not only made a more elaborare and coherent doctrinal corpus than the Greeks, but also these theories might connect, "salvatis salvandis", with the modern structural Linguistic.

La fábula en Educación Primaria. El caso de La cigarra y la hormiga

[CASTELLANO] Desde su lejano origen, la fábula siempre se ha relacionado con la enseñanza debido a su intención moralizante, por lo que siempre se ha clasificado entre los géneros didácticos. El análisis y comparación de las diferentes versiones que se han llevado a cabo de la fábula La cigarra y la hormiga han permitido comprobar la evolución que ha tenido tanto la fábula en sí misma, como el mensaje que se transmite en ella, el cual se transforma dependiendo del contexto histórico en el que esté escrita. Además, ciertas características de la fábula posibilitan su uso como instrumento didáctico en Educación Primaria con el fin de lograr diferentes objetivos.

Lehen Hezkuntzako ingeleseko testuliburuak. Euskal Autonomia Erkidegoan erabiltzen diren materialen analisia

[eus] Ikerketa honen bidez, Euskal Autonomia Erkidegoan erabiltzen diren Lehen Hezkuntzako lehenengo zikloko ingeleseko testuliburuak hizkuntzen ikaskuntzaren teoriei, Europako Erreferentzia Marko Bateratuari eta Curriculum dokumentuei egokitzen zaizkien baieztatu nahi izan da. Horretarako, aipatutako teorietan eta dokumentuetan oinarrituta, sei aldagai diseinatu eta, horiek erabiliz, Euskal Autonomia Erkidegoan erabiltzen diren sei testuliburu aztertu dira. Ikerketatik ondorioztatzen da aztertutako testuliburuak ez datozela bat legediaren ikuspegi komunikatiboarekin ezta atazetan oinarritutako ikaskuntzarekin ere. Hala ere, hizkuntzaren inputa testuinguruan ematen dute eta, Curriculumean eskatzen den bezala, aspektu kulturalak lantzen dituzte.

Ondarroako haurren jariotasuna eta lexikoaren azterketa

[eus] Jakina da eskolan arrakasta izateko hizkuntzaren erabilera aldagai garrantzitsua dela. Hori horrela, lan honetan 4-7 urte bitarteko hamabi neska mutilen jariotasuna eta lexikoaren ezagutza aztertzen dira. Betiere, kontuan izanda haur horien ama hizkuntza ezberdina dela, hots, euskara edota erdara (atzerriko edozein hizkuntza). Helburua herriko hizkera lagunartean (eskolan) bertan gauzatzen dela frogatzea da. Horretarako, haur hauek galdetegi baten bidez elkarrizketatu dira. Jarraian transkribatu eta honen azterketa linguistikoa egin da, jariotasuna eta lexiko aztertuz. Azkenik, konparaketa taulez baliatuz galdetegietako emaitzak aztertu dira eta zenbait haurrek hitz egiterako orduan erakusten duten jariotasuna handitu ahal izateko eskolan lantzeko zenbait proposamen egin dira.

Quantum Emulation of Gravitational Waves

Gravitational waves, as predicted by Einstein's general relativity theory, appear as ripples in the fabric of spacetime traveling at the speed of light. We prove that the propagation of small amplitude gravitational waves in a curved spacetime is equivalent to the propagation of a subspace of electromagnetic states. We use this result to propose the use of entangled photons to emulate the evolution of gravitational waves in curved spacetimes by means of experimental electromagnetic setups featuring metamaterials.

Learning Multirobot Hose Transportation and Deployment by Distributed Round-Robin Q-Learning

Multi-Agent Reinforcement Learning (MARL) algorithms face two main difficulties: the curse of dimensionality, and environment non-stationarity due to the independent learning processes carried out by the agents concurrently. In this paper we formalize and prove the convergence of a Distributed Round Robin Q-learning (D-RR-QL) algorithm for cooperative systems. The computational complexity of this algorithm increases linearly with the number of agents. Moreover, it eliminates environment non sta tionarity by carrying a round-robin scheduling of the action selection and execution. That this learning scheme allows the implementation of Modular State-Action Vetoes (MSAV) in cooperative multi-agent systems, which speeds up learning convergence in over-constrained systems by vetoing state-action pairs which lead to undesired termination states (UTS) in the relevant state-action subspace. Each agent's local state-action value function learning is an independent process, including the MSAV policies. Coordination of locally optimal policies to obtain the global optimal joint policy is achieved by a greedy selection procedure using message passing. We show that D-RR-QL improves over state-of-the-art approaches, such as Distributed Q-Learning, Team Q-Learning and Coordinated Reinforcement Learning in a paradigmatic Linked Multi-Component Robotic System (L-MCRS) control problem: the hose transportation task. L-MCRS are over-constrained systems with many UTS induced by the interaction of the passive linking element and the active mobile robots.

The SD-prekernel for TU games

We introduce and analyze a new solution concept for TU games:The Surplus Distributor Prekernel. Like the prekermel, the new solu- tion is based on the an alternative motion of complaint of one player against other with respect to an allocation. The SD-prekernel contains the SD-prenucleolus and they coincide in the class of convex games. This result allows us to prove that in bankruptcy problems the SD-prekernel and the Minimal Overlapping rule select the same allocation.
