Automated vehicles' work planning in flexible manufacturing systems

2006

The problem of rules setting in coordination of automated vehicles access to shared system resources (sections of their transportation paths) which assure a deadlock free and starvation free flow of the executed processes belongs to NP-hard problems. Assuming that there are local (controlling access to shared resources) rules of priority dispatching, the problem deals with setting conditions sufficient for a pair (initial state, set of priority dispatching rules). The assumed knowledge base way of specifying a transportation subsystem leads to solving a logic-algebraic method decision problem. In this regard, the working knowledge representation synthesis method constitutes a significant co…

A hybrid scheme for action representation

1993

Strong deficiencies are present in symbolic models for action representation and planning, regarding mainly the difficulty of coping with real, complex environments. These deficiencies can be attributed to several problems, such as the inadequacy in coping with incompletely structured situations, the difficulty of interacting with visual and motorial aspects, the difficulty in representing low-level knowledge, the need to specify the problem at a high level of detail, and so on. Besides the purely symbolic approaches, several nonsymbolic models have been developed, such as the recent class of subsym-bolic techniques. A promising paradigm for the modeling of reasoning, which combines feature…

Are there individual concepts? Proper names and individual concepts in SI—Nets

1989

We discuss some aspects of the role played by descriptional knowledge in expressions denoting individual objects. In knowledge representation systems such as KL-ONE and KRYPTON which use semantic networks to express descriptional information, the problem is to establish whether the use of individual concepts in a network is justified. In the light of theoretical and applicational considerations, in the proposed solution only definite descriptions are considered as being characterizable by means of definitions. Vice versa, proper names, in the strict sense, will be treated as having no definitional dimension, and as such only appear in the assertional knowledge base. A description is given o…

On Line Elaboration of a Mental Model During the Understanding of an Animation

2006

This experiment examines how, high and low mechanical and spatial abilities, learners understand an animation. Two variables were manipulated: the controllability of the animations and the task type of the learners to study the device. The comprehension test results indicated a positive effect of a fully controllable animation and also a positive effect of task type, when the attention of the learner is focused on the functional model and on local kinematics. The eye tracking data indicated that the learners attend more to the areas of the animations where a great amount of motion is involved along the causal chain of events. We show an effect of the controllability of the system and of the…

Knowledge Representation in Travelling Texts:from Mirroring to Missing the Point

2014

<p><em>Today, information travels fast. Texts travel, too. In a corporate context, the question is how to manage which knowledge elements should travel to a new language area or market and in which form? The decision to let knowledge elements travel or not travel highly depends on the limitation and the purpose of the text in a new context as well as on predefined parameters for text travel. For texts used in marketing and in technology, the question is whether culture-bound knowledge elements should be domesticated or kept as foreign elements, or should be mirrored or moulded—or should not travel at all! When should semantic and pragmatic elements in a text be replaced and by w…

La natura delle cose

2022

The reference to the nature of things is still working today in legislation and jurisprudence. In this article the reasons for the persistence of this line of reasoning in law and in the legal science are examined. These reasons generally depend on the close connection between law and some fundamental social relations. But also the essential need to assure its effectiveness, without which law would be useless. In turn, the contemporary evolution of the legal culture requires a change in the way of understanding the nature of things. Nowadays, the nature of things distances itself from mere objectivism to get close to the deliberative character of the determination of the law

On "Coherence" and "Law": An Analysis of Different Models

2001

The aim of this paper is to compare different conceptions of the role of (normative) coherence in the legal field. More precisely, it aims to deepen Neil MacCormick's theory of legal reasoning, in which coherence is essentially considered an interpretative tool, and Ronald Dworkin's legal theory, in which coherence occupies a more crucial place. The main results of this paper can be summarized in two points. A) For Dworkin, coherence is not just an interpretative standard but constitutes the hard core of his theory of law. B) As a consequence of A, Dworkin's reflections on coherence (as an interpretative standard) cannot be separated from his theory of law grounded on the concept of integri…

Neil MacCormick's Second Thoughts on Legal Reasoning and Legal Theory. A Defence of the Original View

2011

This paper offers a diachronic reconstruction of MacCormick's theory of law and legal argumentation: In particular, two related points will be highlighted in which the difference between the perspective upheld in Legal Reasoning and Legal Theory and the later writings is particularly marked. The first point concerns MacCormick's gradual break with legal positivism, and more specifically the thesis that the implicit pretension to justice of law proves legal positivism false in all its different versions. The second point concerns MacCormick's acceptance of the one-right-answer thesis and the consequent thinning of the differences between MacCormick's theory of legal reasoning and that of Ron…

'Tell Us Only What You Know': Evidentiality in the Discourse of Participants in Spanish Trials

2019

El objetivo de esta propuesta es explorar el uso de la evidencialidad en los juicios españoles y su relación con las convenciones del género y los roles de los participantes en estos eventos discursivos. Para ello, basamos nuestro estudio en un análisis cuantitativo-cualitativo de un corpus transcrito de ensayos orales en español. La evidencialidad es una categoría semántico-funcional que incluye dispositivos lingüísticos que marcan la fuente de información detrás de las declaraciones del hablante. El marcado explícito de la fuente no es obligatorio en español; sin embargo, en géneros específicos (legal, parlamentario y académico), se convierte en una poderosa herramienta argumentativa para…
