Synthetic evaluation of territorial sustainability : strengths and weaknesses of modeling in the planning process
2017
This thesis work is based on issues aimed at assessing the impacts of planning decisions in the light of the imperatives of sustainable development. Beyond the vagueness that often emerges from this concept, the aim here is to reflect on a better balance to be found between the three fields generally identified as pillars of sustainable development: the economic, the social and the environmental. The objective is part of the following reflection: how to evaluate the impacts of management policies in each of these three pillars, and what conclusions to draw from them? The aim here is to provide answers by assessing the performance of the territories studied in these three pillars of sustaina…
Towards A New Decision Support System for Design, Management and Operation of Wastewater Treatment Plants for the Reduction of Greenhouse Gases Emiss…
2015
The increasing attention paid to the environment has led to a reduction in the emissions from wastewater treatment plants (WWTPs). Moreover, the increasing interest in the greenhouse gas (GHG) emissions from WWTPs suggests that we reconsider the traditional tools used for designing and managing WWTPs. Indeed, nitrous oxide, carbon dioxide and methane can be emitted from wastewater treatment, significantly contributing to the greenhouse gas (GHG) footprint. The reduction of energy consumption as well as GHG emission are of particular concern for large WWTPs which treat the majority of wastewater in terms of both volume and pollution load. Nowadays, there is an increasing need to develop new …
Ionic tactile sensors as promising biomaterials for artificial skin: Review of latest advances and future perspectives
2021
Abstract Ionic tactile sensors (ITS) are an emerging subfield of wearable electronics, capable of mimicking the human skin, including not only the typical anisotropic structure, mechanical behaviour, and tactile functions but even the mechanosensitive ionic channels that are crucial for the human sense of touch. With the rapid development of intelligent technology, such bioinspired materials constitute the core foundation of intelligent systems and are a candidate to be the next generation e-skins, offering a more accurate and evolved biointerface. In the latest years, a wealth of novel ultra-stretchable ITS was proposed, progressively refining the choice of soft materials, including ion ge…
Nuove strategie gestionali per la competitività di un terminal container di transhipment: sviluppo di strumenti di supporto alle decisioni per la pia…
2012
In a container terminal task assignment optimization may not be sufficient to ensure efficiency. By contrast, a systemic approach to terminal operations planning is required to ensure efficient coordination day by day of the all the operations in-volved. As far as management is concerned, a number of interacting factors need to be taken into account, ranging from prediction of ships’ arrivals to manpower and vehicles optimization strategies for the different work shifts. This paper describes three modules comprising a Decision Support System designed to assist port operations planners: - Ships’ arrivals forecasting module; - Optimal human resources allocation module; - Maintenance process e…
Pragmatism in Decision Support System Research
2018
Decision making on relief distribution is a complex multidisciplinary task in humanitarian logistics. It incorporates decision makers from different but related problem areas. The failure to perform assigned decision-making tasks in any area makes the entire system unstable and delays the relief distribution process. An organized, well-planned, and practical decision support system (DSS) can assist practitioners in making rapid decisions on delivering relief items. Hence, DSS researchers in humanitarian logistics require rigorous thinking, close and critical analysis, and the identification of challenges to conduct research or validate the generated knowledge properly. To perform such compl…
Possibilistic Programming and Gas for Aggregate Production Planning under Vague Information
1999
In production planning activities, aggregate planning is surely the phase where the lack of information is more relevant. The reasons for that can be summarised in: a) the planning product is an aggregate one, very often not corresponding to actual products; b) the delay from the actual production is relevant so that information regarding actual production resources availability and performances are vague; c) the planning activity is often based on forecasts. On the other hand, all the subsequent production planning activities are based on the result of aggregate planning. In the paper a research going on at the Workgroup for Soft Computing Application in Manufacturing is presented. A Decis…
Prognostic scoring system predictive of survival after surgical resection of esophageal carcinoma.
2013
BACKGROUND The aim of our study was to develop a prognostic index score for patients undergoing surgical resection for esophageal cancer that accurately determines survival with specific clinicopathological characteristics. METHODS Clinical, histological, and demographical variables of 475 patients were entered in an univariate and multivariate regression model, followed by individual calculation of the Prognostic Indicator Score and model validation via simulation. RESULTS Significant variables included in the scoring system were number of positive lymph nodes, pT, pL, R, obesity, and American Society of Anesthesiologist classification. Survival probability and its associated hazard functi…
Automated quality control protocol for MR spectra of brain tumors.
2008
Item does not contain fulltext eTUMOUR (http://www.etumour.net/) is acquiring a large database of brain tumor (1)H MR spectra to develop automated pattern recognition methods and decision support system (DSS) for tumor diagnosis. Development of accurate pattern-recognition algorithms requires spectra undistorted by artifacts, low signal-to-noise, or broad lines. eTUMOUR currently uses panels of expert spectroscopists to subjectively grade spectra as being acceptable or unacceptable. Automated quality control (QC) would be more satisfactory for several reasons: 1) to provide a reproducible objective classification of spectrum quality; 2) for use within the future DSS to prevent misdiagnosis …
Enterprise Knowledge Modeling, UML vs Ontology: Formal Evaluation
2019
International audience; Everyday activities in enterprises rely heavily on the experts' know-how. Due to experts departure, the loss of expertise and knowledge is a reoccurring problem in these enterprises. Recently, in order to capture experts knowledge into intelligent systems, formal knowledge representation methods, such as ontologies, are being studied and have caught up with non-formal or semi-formal representation, such as UML. The similarities and differences between UML class diagram and computational ontology have for long raised questions about the possibility of synthesizing them in a common representation (usually an ontology). Indeed, the problem of migrating knowledge encoded…
Groupware Support for Requirements Management in New Product Development
2005
Large high-technology companies operate in fiercely competitive international markets. To succeed, they need to shorten the cycle time of new product development (NPD) while improving product quality and maintaining or reducing the total resources required. Their abilities to meet these business goals depend on how extensively and effectively they collect, analyze, and utilize requirements in their product development. Creating and sharing such knowledge is complicated partly because the NPD activities of large companies are geographically distributed. Groupware technologies allow knowledge to be created and shared more effectively. Thus, they hold considerable potential as means of meeting…
