CEFLES2: The remote sensing component to quantify photosynthetic efficiency from the leaf to the region by measuring sun-induced fluorescence in the …
2009
The CEFLES2 campaign during the Carbo Europe Regional Experiment Strategy was designed to provide simultaneous airborne measurements of solar induced fluorescence and CO<sub>2</sub> fluxes. It was combined with extensive ground-based quantification of leaf- and canopy-level processes in support of ESA's Candidate Earth Explorer Mission of the "Fluorescence Explorer" (FLEX). The aim of this campaign was to test if fluorescence signal detected from an airborne platform can be used to improve estimates of plant mediated exchange on the mesoscale. Canopy fluorescence was quantified from four airborne platforms using a combination of novel sensors: (i) the prototype ai…
La modernisation de la Justice au Sénégal : vers la recherche de la performance
2018
My thesis project focuses on the challenges of modernizing the justice system. The reason for this choice is that Senegal, after having originally set up a dual system of juridiction in 1960, made major reforms of its judicial organization in 1984,1992, 2008 and ultimately in 2015. Meanwhile,the country signed the Port Louis Treaty establishing the OHADA which set up a common Court of Justice and Arbitration, a Judicial Academy and led to adoption of 10 uniform acts that govern the business law in the 17 member states. Senegal was the first country sign the treaty of Rome establishing the International Crininal Court and after receiving a mandate from the African Union to try the former Pre…

Event selection efficiency vs mean proper decay length The MH, HH, ML suffix used for overlaying the graphs refers to the combinations of squark and neutralino masses in the signal MC sample: MH is 700GeV squarks and 494GeV neutralinos, HH is 1.5TeV squarks and 494GeV neutralinos, and ML is 700GeV squarks and 108GeV neutralinos. The tables show the efficiency for reconstructing a signal event, where at least one vertex candidate passes all selection requirements, as a function of the proper decay length c*tau of the neutralino.

Efficiency-vs-radial-vertex-position without re-tracking The efficiency for reconstructing a displaced vertex passing all cuts, as a function of radial distance from the z-axis to the vertex positon. The retrack and noretrack suffixes refer to whether or not the procedure known as re-tracking, where the tracking algorithm is re-run with looser cuts, on the leftover hits from standard tracking, was used to select the tracks that were input to the vertexing algorithm.

Energy efficiency analysis in Incremental Sheet Forming operations
2012
In literature, manufacturing processes have been studied with different approaches, but a lack in terms of their environmental impact and energy required is still present. The aim of this paper is to compute some energy efficiency analysis on a specific manufacturing process. More in detail, the attention will be focused on the Incremental Sheet Forming process in order to evaluate the required energy and how it changes for changing process conditions. Accordingly, a wide experimental investigation has been executed taking into account different process parameters (i.e. tool depth step, punch diameter, wall inclination angle and sheet thickness). The total energy consumption has been monito…
Evaluating the Eco-Efficiency of Wastewater Treatment Plants: Comparison of Optimistic and Pessimistic Approaches
2020
The assessment of wastewater treatment plant (WWTP) performance has gained the interest of water utilities and water regulators. Eco-efficiency has been identified as a powerful indicator, as it integrates economic and environmental variables into a single index. Most previous studies have employed traditional data envelopment analysis (DEA) for the evaluation of WWTP eco-efficiency. However, DEA allows the selection of input and output weights for individual WWTPs for the calculation of eco-efficiency scores. To overcome this limitation, we employed the double-frontier and common set of weights methods to evaluate the eco-efficiency of a sample of 30 WWTPs in Spain. The WWTPs were ranked b…
Comparing changes in productivity among private water companies integrating quality of service: A metafrontier approach
2019
Abstract Most previous studies evaluating the effect of ownership on the performance of water companies have ignored the fact that there are several types of private water companies. In this study, we instead recognize that private water companies can differ considerably in how they are managed, based on whether their infrastructure is privately or publicly owned. We estimated change in productivity of fully-privatized companies and concessionary companies by employing the metafrontier Malmquist Luenberger productivity (MMLP) index, which allowed us to integrate quality-of-service variables as undesirable outputs. We segregated the MMLP index to assess changes over time in relative efficien…
