SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT
2011
8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …
Ontological Analysis of the Project Risk Management Concept ‘Risk’
2018
Abstract The aim of the current research series is to examine the definitions of the concept ‘risk’ and analyze the concepts used in the definitions of ‘risk’ in the sources of these definitions in order to perform the ontological analysis of the concept of ‘risk’. Ontological and epistemological analysis of the concepts in the definition of the concept ‘risk’ was used to answer the question what ‘risk’ means in project management. This investigation represents a part of the research series where the ontological, epistemological and methodological analysis of project risk is performed with the aim to improve risk registers and risk management as a whole. In the previous studies the author a…
From common operational picture to common situational understanding: An analysis based on practitioner perspectives
2021
Abstract The concepts of Situational Awareness (SA) and Common Operational Picture (COP) are closely related and well-acknowledged to be crucial factors for effective emergency management. In multi-agency operations, such as extreme weather events, the involved first responders manage the event with different mandates, objectives, and tools which can make it challenging to build a COP. Effective collaboration requires a common situational understanding, based on knowledge about each other’s responsibilities and tasks, mutual respect and trust, as well as common communication tools for emergency communication and information sharing. This paper argues that the COP serves as a basis for decid…
Taking the Advantage of Smartphone Apps for Understanding Information Needs of Emergency Response Teams’ for Situational Awareness: Evidence from an …
2016
In search and rescue (SAR) operation, a lot of information is being shared among different emergency response groups. However, one of the key challenges experienced by these rescue groups during SAR operation is obtaining the complete awareness of the situation from the shared information. Moreover, one of the key actions of rescue leaders is to get the needed information in order to coordinate effectively with other teams and perform well. So, in this study we conduct an indoor fire drill with the help of Smartphone application with two settings (without SmartRescue smartphone application and with SmartRescue smartphone application) to find out what type of information is mostly communicat…
Visual communication in lean organizations
2017
Many researchers have studied the role and importance of communication and communication types for organizations and their work force. The topic of organizational communication is a constantly changing one. The thing that remains stable throughout this very wide topic is its purpose: communication is vital for the effectiveness and success of organizations of all sizes, types and cultures. In terms of type, one could split up topic by type as followed: verbal, visual and written. This research paper focuses on the visual component at shop floor within automotive organizations. It aims at giving the reader a structured overview on the most appropriate but also lean visual communication pract…
Empowering leadership, mindful organizing and safety performance in a nuclear power plant: A multilevel structural equation model
2020
Abstract The aim of this paper is to develop and test a model in which empowering leadership is expected to contribute to developing mindful organizing, which in turn should contribute to safety compliance and safety participation. Empowering leadership was measured at Time 1, and the rest of the variables were measured two years later (Time 2). The sample used for the analyses in this study included 49 teams and 200 employees from a company in the nuclear generation industry with three different sites. The multilevel structural equation analysis performed to test the proposed model revealed an acceptable fit, and most of the paths were statistically significant and presented the expected s…
How relational contract theory influence management strategies and project outcomes: a systematic literature review
2021
Despite growing interest in Relational Contracting (RC), few studies have comprehensively investigated the qualities required for a successful RC project. Macneil’s ten norms are principles of behaviour in contracts based on the application of relational contract theory and play an essential role in the formation and agreement of parties and their commitment to means and objectives. In contributing a missing dimension to the RC approach in construction, the purpose of this research is to conduct a systematic review of studies of relational contracting to answer the question: In what ways can the influence of RC theory be observed in the management strategies and outcomes of relational proje…
Palais et fisc à l'époque carolingienne: Attigny
1982
Domaine rural acquis par Clovis II en 651, Attigny fut une résidence du maire du palais Pépin à partir de 749. Devenu un palais avec l'avènement des Carolingiens, il cessa d'être fréquenté après 931. La fonction essentielle de ce palais découle de sa situation géographique située à proximité de la voie romaine Reims-Trêves, la localité constituait une étape commode entre est et ouest du royaume franc, puis entre les royaumes de Francie occidentale et de Lotharingie. Le fisc d'Attigny, mentionné pour la première fois en 877, peut être connu par l'analyse de trois diplômes, dont deux très postérieurs à la période carolingienne. Il englobait au début du Xe siècle au moins trois mille cinq cent…
Flexural behavior of external beam-column reinforced concrete assemblages externally strengthened with steel cages
2016
In this paper, an experimental study referring to the flexural behavior of full-scale external beam-column joints externally strengthened with steel angles and strips and subjected to cyclic reversal loading is presented. One control specimen and five other specimens having the same characteristics as the control specimen but strengthened with steel angles and strips along beams and columns, and characterized by different configurations of strengthening in the critical regions, were tested. The control specimen was designed with a weak column and strong beam to reproduce the most common cases of old frame structures in the Mediterranean area, which were designed only for gravity loads and a…
Determining the Environmental Benefits of Ultra High Performance Concrete as a Bridge Construction Material
2017
Ultra High Performance Concrete (UHPC) is a material that is attracting attention in the construction industry due to the high mechanical strength and durability, leading to structures having low maintenance requirements. The production of UHPC, however, has generally higher environmental impact than normal strength concrete due to the increased demand of cement required in the concrete mix. What is still not sufficiently investigated, is if the longer lifetime, slimmer construction and lower maintenance requirements lead to a net environmental benefit compared to standard concrete bridge design. This study utilizes life cycle assessment (LCA) to determine the lifetime impacts of two compar…
