The Value of the Useless in the Urban Landscape of Small Islands
2015
Abstract. In the variety of the Italian landscape-cultural mosaic, the morphology of Favignana (Egadi Islands) is the outcome of the long-term relationship between natural environment and human actions that has drawn both natural and urban landscape. This relationship, that constitutes the Favignana’s architectural and landscape heritage, is often denied or forgotten because of transformations caused by a new demand of efficiency (usefulness?) in reference to an economic policy based on the tourism-related activities. In this case-study, the Analytic Network Process (ANP) (selected among the Multicriteria Analysis techniques because of its holistic approach) has applied to support the choic…
Genome and phenotype microarray analyses of rhodococcus sp. BCP1 and rhodococcus opacus R7: Genetic determinants and metabolic abilities with environ…
2015
In this paper comparative genome and phenotype microarray analyses of Rhodococcus sp. BCP1 and Rhodococcus opacus R7 were performed. Rhodococcus sp. BCP1 was selected for its ability to grow on short-chain n-alkanes and R. opacus R7 was isolated for its ability to grow on naphthalene and on o-xylene. Results of genome comparison, includ- ing BCP1, R7, along with other Rhodococcus reference strains, showed that at least 30% of the genome of each strain presented unique sequences and only 50% of the predicted proteome was shared. To associate genomic features with metabolic capabilities of BCP1 and R7 strains, hundreds of different growth conditions were tested through Phenotype Microarray, b…
AUGMENTED REALITY
2011
Already used in very specific areas such as in military and medical or academic research, in 2009 thanks to improved technology, augmented reality is to reach wider audiences and as information campaigns, advertising-augmented published in newspapers or on the network, and through a growing number of applications for mobile phones, particularly iPhone. "The Augmented Reality on the desktop computer is based on the use of markers, or ARtags, and stylized drawings, which are shown to the webcam, are recognized by the PC, and which are overlaid in real-time multimedia content: video, audio , 3D objects, etc.. Normally, applications of augmented reality are based on Adobe Flash technology and t…
Towards a Comprehension of University Dropout in Catalonia: the Case of Universitat Autònoma de Barcelona
2015
The article presents the results of a research that aims to unfold the reasons behind students’ dropout at the Autonomous University of Barcelona (UAB). Data is analyzed, and interviews and focus groups with students who have dropout, study degree’s coordinators and institutional authorities are carried out. Results indicate that part of the abandonment taking place is voluntary, natural and even necessary, when the student does not enter the desired option or discovers that the studies do not fi t with their vocational interests, but it also represents a misalignment between the academic offer and the students’ capabilities, performance and motivation.
Machine learning of microbial interactions using abductive ILP and hypothesis frequency/compression estimation
2021
Interaction between species in microbial communities plays an important role in the functioning of all ecosystems, from cropland soils to human gut microbiota. Many statistical approaches have been proposed to infer these interactions from microbial abundance information. However, these statistical approaches have no general mechanisms for incorporating existing ecological knowledge in the inference process. We propose an Abductive/Inductive Logic Programming (A/ILP) framework to infer microbial interactions from microbial abundance data, by including logical descriptions of different types of interaction as background knowledge in the learning. This framework also includes a new mechanism …
Apprentissage automatique de réseaux d'interaction à partir de données de séquences de nouvelle génération
2022
Climate change and other human-induced processes are modifying ecosystems, globally, at an ever increasing rate. Microbial communities play an important role in the functioning ecosystems, maintaining their diversity and services. These communities are shaped by the different abiotic environmental effects to which they are subjected and the biotic interactions between all community members. The ANR Next-Generation Biomonitoring (NGB) project proposed to reconstruct interaction networks from abundance measures obtained sequencing environmental DNA (eDNA) and to use these networks to monitor ecosystem change. In this thesis, conducted as part of the NGB project, I evaluate the potential of tw…
A heuristic algorithm for project scheduling with splitting allowed
1996
In this article, we analyze the precedence diagramming method, the only published algorithm for time-only project scheduling with activity splitting allowed. The criteria used in this method (forward and backward pass computations) for deciding when an activity has to be interrupted are shown to be invalid in some situations. We look into the causes of these failures and propose new formulae that always provide feasible solutions. The new algorithm has been tested on 240 randomly generated problems ranging up to 600 activities and 7,200 precedence relationships, resulting in an average deviation from optima of less than 1 percent.
Acoustic characterization of Silica aerogel clamped plates for perfect absorption purpose
2017
International audience; Silica aerogel has been widely studied as bulk material for its extremely low density and thermal conductivity. Plates or membranes made of this extremely soft materials exhibits interesting properties for sound absorption. A novel signal processing method for the characterization of an acoustic metamaterial made of silica aerogel clamped plates is presented. The acoustic impedance of a silica aerogel clamped plate is derived from the elastic theory for the flexural waves, while the transfer matrix method is used to model reflection and transmission coefficients of a single plate. Experimental results are obtained by using an acoustic impedance tube. The difference b…
