Le formalisme conventionnel : illustration de la notion de contrat-cadre

1986

The usual contract is an agreement which creates obligations. The framework contract is an agreement which produces norms. This paper will outline the general theory of the framework contract, illustrated by one of it's multiple practical applications : the conventional formalism which incorporates those agreements determining the nature of expression or communication of intention in future juristic acts.

Les problèmes de preuve posés par l'évolution des sciences et des technologies

2001

International audience; That law is seeking for truth is certainly not new. However, proof and scientific expertise have received increasingly attention in the context of legal evidence. What are the relationship between scientific truth and legal evidence ? The aim of this paper is neither to assess the potential conflict between scientific truth and legal evidence, nor to measure in what extend scientific method might be applied to legal decision-making process. The paper is rather an attempt to point out some problems caused by scientific discoveries and technological advances in the context of legal evidence. Scientific progress is a chain of certainties and uncertainties. From their pr…

Leveraging the benefits of big data with fast data for effective and efficient cybersecurity analytics systems : A robust optimisation approach

2020

In recent times, major cybersecurity breaches and cyber fraud within the public and private sectors are making international headlines. Majority of organisations are facing cybersecurity adversity and advanced threats. On the one hand, we have asynchronous cybersecurity practices, many standards and frameworks to consider while on the other hand, we have to deal and secure our organisations against cyber-criminals, organised hacktivists, insider threats, hackers and nation-states with malafide intentions. The Center for Cyber Safety and Education's Global Information Security Workforce Study (GISWS) confirms that globally we are not only loosing but also backpedalling against threats and ri…

Today fuel cell (FC) technology is envisaged as a strategic alternative for providing clean energy through the exploitation of renewable sources; FC research is substantially funded by governments as a mean to meet the global market demand of zero environmental impact. Due to the high level of efficiency, FC devices are already able to compete with the existing power generation technologies and, in particular, solid oxide fuel cells (SOFCs) plants for stationary application constitute one the most efficient way to produce electric power and heat. Nowadays, the main challenges for SOFC research activity are: i) improving costs and durability, by reducing the operating temperature from ∼1000°…

Unification of Graphs and Relations in Mizar

2020

Summary A (di)graph without parallel edges can simply be represented by a binary relation of the vertices and on the other hand, any binary relation can be expressed as such a graph. In this article, this correspondence is formalized in the Mizar system [2], based on the formalization of graphs in [6] and relations in [11], [12]. Notably, a new definition of createGraph will be given, taking only a non empty set V and a binary relation E ⊆ V × V to create a (di)graph without parallel edges, which will provide to be very useful in future articles.

Export Barrier Perceptions in Tanzania: The Influence of Social Networks

2012

In this article, the author empirically examines export barriers Tanzanian firms encounter in attempting to initiate and/or expand export activities and the strategies they use for overcoming these barriers. Based on a social network perspective, the research hypothesizes that firms exploiting diverse networks should normally encounter fewer export barriers. Using a survey dataset collected from 122 manufacturing firms, the findings support the notion that networking reduces export barriers. More specifically, exploiting a large number of strong ties relative to weak ties, and a large number of institutional ties relative to business ties, can substantially enhance firms’ capabilities of ov…

Biometric Features for Mobile Agents Ownership

2005

Multi-Agent System (MAS) architectures can be used for e-Business application due their flexibility, scalability and interoperability. Agent ownership implies that a specific person or organization (the owner) is responsible for the agent's actions. Agents, whose ownership was certainly fixed, could operate on behalf of their owner to make transactions, to buy or sell products. Security requirements in the agent ownership setting process are the identification of the owner and the protection of the identification information carried by an agent. In this paper, we investigate the possibility of using biometrics in mobile agent systems for owner authentication. Biometric features can be used …
