Search engines help people but they face user with a large amount of results, mostly useless, and he have to select one by one the right satisfying needs. To focus the attention on user requirements and involving the(More)
Extreme Programming (XP) is an Agile Methodology (AM) which doesn't require any specific supporting tool for being successfully applied. Despite this starting observation, there are many reasons leading a XP team to adopt Web based tools to support XP practices. For example, such tools could be useful for process and product data collection and analysis or(More)
In this paper, we describe our approach and its results for the MediaEval 2015 Retrieving Diverse Social Images task. The main strength of the proposed approach is its flexibility that permits to filter out irrelevant images, and to obtain a reliable set of diverse and relevant images. This is done by first clustering similar images according to their(More)
Ratios of azimuthal angle correlations between two jets produced at large rapidity separation are studied in the N = 4 maximally supersymmetric Yang-Mills (MSYM) theory. It is shown that these observables, which directly prove the SL(2,C) symmetry present in gauge theories in the Regge limit, exhibit an excellent perturbative convergence. They are compared(More)
