Two-view “cylindrical decomposition” of binary images
2001
This paper describes the discrete cylindrical algebraic decomposition (DCAD) construction along two orthogonal views of binary images. The combination of two information is used to avoid ambiguities for image recognition purposes. This algorithm associates an object connectivity graph to each connected component, allowing a complete description of the structuring information. Moreover, an easy and compact representation of the scene is achieved by using strings in a five letter alphabet. Examples on complex digital images are also provided. © 2001 Elsevier Science Inc.
UML-Based Reliability Modeling of Network Services, a UDP Echo Service Case Study
2009
In the paper, we discuss state space reliability modeling formalism of distributed systems and services compliant with UML metamodel. Behavior of modeled application system we describe in terms of states. Service generation process we represent as a sequence of application system states. State space approach allows us to define dependence between application system components via dependence between components states and states input, output parameters. Reliability of application system component we define for each simply action state. Reliability of a service we express by components reliability in states determined by service generation process. As an example, we analyze reliability of cli…
Weakening Forensic Science in Spain: From Expert Evidence to Documentary Evidence*
2012
An amendment in 2002 to the Spanish Code of Criminal Procedure converted into documentary evidence the expert reports prepared by official laboratories aimed at determining the nature, weight, and purity of seized drugs. In most cases, experts are spared from appearance before the courts. This is likely to be extended to other forensic fields. After an overview of criminalistic identification in current forensic science, the objectivity and reliability concepts used by jurists and scientists are considered by comparing the paradigm of individualization with that of likelihood. Subsequently, a detailed critical study is made on the above-mentioned Spanish legal reform, and a comparison is ma…
Constraint Management in Engineering of Complex Information Systems
2009
We propose to build an engineering environment for information systems by using metamodels, OCL and symbolic model checkers to manage constraints. Our proposal is based on a definition of constraints as 3D spaces with dimensions corresponding to UML diagrams, constructs, and abstraction levels. We show how such environments can help with engineering quality complex systems by allowing to lift up a part of constraint verifications.
A Research Review on Building Information Modeling in Construction―An Area Ripe for IS Research
2012
Published version of article of an article in the journal: Communications of the Association for Information Systems. Also available from the publisher : http://http://aisel.aisnet.org/cais/vol31/iss1/10/ This article presents a review of the research on Building Information Modeling (BIM) in construction, with the aim of identifying areas in this domain where IS research can contribute. The concept of BIM comprises an infrastructure of IT tools supporting collaborative and integrated design, assembly, and operation of buildings. This integrated construction approach, with all stakeholders editing or retrieving information from commonly shared models, requires major changes to well-establis…
Relations entre le système de consommation et les comportements en magasin : une approche par la valeur : application au vêtement
2011
Within the course of the theory of cultural consumption (CCT), this research aims to enlighten on the relationship between the consumer to hir or her system of consumption. The first part, qualitative, attempts to describe the nature of the relationship between the consumer and his or her system (the wardrobe in our case) through an anthropological study and a semiotic study. The data was collected by way of observation (video and audio taped) during usage experiences. The second part, quantitative, measures separately the sedimentation of value linked to usage and shopping experiences. Applied to the clothing market, results show the value of the organisational and systemic concerns (which…
A review on optimization and cost-optimal methodologies in low-energy buildings design and environmental considerations
2019
Abstract The topic of low-energy buildings received a widespread and growing interest in last years, thanks to energy saving policies of developed countries. The design of a low-energy building is addressed with energy saving measures and renewable energy generation, but the correct assessment of phenomena occurring in a building usually requires to perform dynamic simulations and to analyze multiple scenarios to attain the optimal solution. The optimality of a technical solution may be subject to contrasting constraints and objectives. For this reason, designers may employ mathematical optimization techniques, a non-familiar topic to most of building designers. In this paper, a review on o…
Sport tourism consumer experiences: a comprehensive model
2004
The interest in physical activity and vacations has created a growth in the tourism industry and has greatly modified strategies within the industry. Sport tourism is expanding and many forms of consumption exist within this area. The object of this study is to propose a new framework for analysing sport tourism consumption. This framework illustrates that consumer choices depend upon vacation destinations and sport services offered in relation to the experiences that vacationers are seeking. The originality of this analysis is that it integrates spatial and social dimensions stemming from environmental psychology, ethnology and sociology.
Analysis of the appropriation of a connected object : an experiential and dimensional approach
2022
The evolution and interactivity of connected objects promise a continuous improvement of the consumer experience, especially through the adaptation of the object and the development of its functionalities. But in some cases, the evolving nature of the object can lead to a situation where the user has to reappropriate it. Through a netnography and an analysis of life stories, this research studies the appropriation process in a dynamic way.The main contribution of this research is the identification of two dimensions (social and situational) and four forms of appropriation : autotelic, instrumental, individual and collective, which we bring closer to Lanier and Rader's (2015) measure of expe…
