Conceptual modelling methods such as ER (Chen, 1976), EER (Elmasri and Navathe, 1994; Gogolla, 1994), KISS (Kristen, 1994), NIAM (Nijssen and Halpin, 1989), OOSA (Embley, Kurtz, and Woodfield, 1992) and ORM (Halpin, 2001) have traditionally been developed with the aim of providing conceptual models of database structures. More recently, however, such modelling methods have shown their use for m...

Giving to computers the ability to talk and understand a natural language conversation is a major field of research. We have developed the HALPIN (Hyperdialogue avec un Agent en Langage Proche de l’Interaction Naturelle) system to implement our multimodal conversational model for information retrieval. This dialogue-oriented interface allows the access to the INRIA's database (Institut National...

Abstract In this study, the first-order shear deformation theory (FSDT) is used to establish a nonlinear dynamic model for conical shell truncated by functionally graded graphene platelet-reinforced composite (FG-GPLRC). The vibration analyses of FG-GPLRC are presented. Considering platelets (GPLs) with three different distribution patterns, modified Halpin-Tsai calculate effective Young’s modu...

Designing computers with the ability to talk and understand a natural language (NL) conversation is a major field of research. We have developed the HALPIN system to implement our multimodal conversational model for information retrieval in a digital library via the World Wide Web. This dialogue-oriented interface allows access to INRIA's database, on the Internet, in a natural language mode. T...

Randomized clinical trials (RCTs) are performed to provide evidence to support treatment decisions. Based on the nature of those studies and the need to avoid confounding factors, it has been argued that the population selected in RCTs only partially represents the real-life population. This assumption casts doubts on the applicability of the results provided by RCTs in the management of indivi...

This paper explores the potential of construction process simulation as a web service. This web service, or web based application, exploits the high accessibility characteristic of the web, to support easier information exchange and peer collaboration. Two concepts are discussed and presented. One web based prototype called “Interactive Simulation System (ISS)” allows a user unfamiliar with sim...

The present work studies an axisymmetric rotating truncated cone made of functionally graded (FG) porous materials reinforced by graphene platelets (GPLs) under a thermal loading. problem is tackled theoretically based on classical linear thermoelasticity approach. consists layered material with uniform or non-uniform dispersion GPLs in metal matrix open-cell internal pores, whose effective pro...
