Approximation algorithm for constrained coupled-tasks scheduling problem
2014
International audience; We tackle the makespan minimization coupled-tasks problem in presence of compatibility constraints. In particular, we focus on stretched coupled-tasks, i.e. coupled-tasks having the same sub-tasks execution time and idle time duration. In such context, we propose some complexity results according to several parameters and we design an efficient polynomial-time approximation algorithm.
A Rayleigh-Ritz approach for postbuckling analysis of variable angle tow composite stiffened panels
2018
Abstract A Rayleigh-Ritz solution approach for generally restrained multilayered variable angle tow stiffened plates in postbuckling regime is presented. The plate model is based on the first order shear deformation theory and accounts for geometrical nonlinearity through the von Karman’s assumptions. Stiffened plates are modelled as assembly of plate-like elements and penalty techniques are used to join the elements in the assembled structure and to apply the kinematical boundary conditions. General symmetric and unsymmetric stacking sequences are considered and Legendre orthogonal polynomials are employed to build the trial functions. A computer code was developed to implement the propose…
Post-buckling analysis of cracked multilayered composite plates by pb-2 Rayleigh–Ritz method
2015
Abstract A pb-2 Rayleigh–Ritz variational approach for the analysis of post-buckling behavior of cracked composite plates is presented. The plate is modeled by the first order shear deformation theory taking geometric nonlinearities into account through the von Karman’s theory. General stacking sequences are considered. Cracks are modeled by using subdomain decomposition of the plate coupled with penalty techniques, used to augment the variational statement with the needed continuity conditions along the connected subdomains edges. Numerical procedures have been developed and used to validate the present solution by comparison with available literature results. Original results are then pre…
Post-Buckling Analysis of Damaged Multilayered Composite Stiffened Plates by Rayleigh-Ritz Method
2016
A Rayleigh-Ritz approach for the analysis of buckling and post-buckling behavior of cracked composite stiffened plates is presented. The structure is modeled as the assembly of plate elements modeled by the first order shear deformation theory and taking geometric nonlinearities into account through the von Karman’s theory assumptions. Continuity along the plate elements connected edges and the enforcement of rigid and elastic restraints of the plate boundaries are obtained by using penalty techniques, which also allow to straightforwardly implement efficient crack modeling strategies. General symmetric and unsymmetric stacking sequences are considered and numerical procedures have been dev…
Psychometric properties of the measure of achieved capabilities in homeless services
2023
Abstract Background Purposeful participation in personally meaningful life tasks, enjoyment of positive reciprocal relationships, and opportunities to realize one’s potential are growth-related aspects of a meaningful life that should be considered important dimensions of recovery from homelessness. The extent to which homeless services support individuals to achieve the capabilities they need to become who they want to be and do what they want to do is, in turn, an important indicator of their effectiveness. In this study, we developed a measure of achieved capabilities (MACHS) for use in homeless services settings, and assessed its construct and concurrent validity. Methods We analysed da…
Offensive and defensive team performance: relation to successful and unsuccessful participation in the 2010 Soccer World Cup
2013
Delgado-Bordonau, J.L., Domenech-Monforte, C., Guzman, J.F. & Mendez-Villanueva, A. (2013). Offensive and defensive team performance: relation to successful and unsuccessful participation in the 2010 Soccer World Cup. J. Hum. Sport Exerc., 8(4), pp.894-904. The present study was conducted to analyze the impact of selected offensive and defensive performance indicators in relation to teams’ success in the 2010 soccer World Cup. The sample used corresponded to 54 matches played in both the group and knockout stage. The game-related statistics gathered were: total shots, shots on goal, shots off goal, % of shots on goal from total shots, % of shots off goal from total shots, offensive and defe…
"Translation and Language Contact in Multicultural Settings. The Case of Asian Migrants in Sicily”
2008
This article addresses the role of translation in the construction of cultural identities in multicultural and host settings. Approaching migration as a form of translation in terms of relexification, cannibalism and hybridization, the essay discusses the example of a new English variety which was developed by Asian immigrants who moved to Sicily. It is suggested that this Indian-Anglo-Italian hybrid variety has been built upon a process of relexification during which Asian immigrants translate their local language into English by keeping the syntactic structure of their native language in the English sentence and by adding a mixture of Sicilian-Italian words. In this context, immigrants ar…
Risk of mortality among children, adolescents, and adults with autism spectrum disorder or attention deficit hyperactivity disorder and their first-d…
2017
BACKGROUND: Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are childhood onset neurodevelopmental disorders that may persist into adulthood. ASD and ADHD tend to run in families and may have a significant negative impact on the health and longevity of those with the disorder and their relatives. The aim of this study will be to analyze the risk of mortality among children, adolescents, and adults with ASD or ADHD and their first-degree relatives. METHODS/DESIGN: We will conduct a systematic review and meta-analysis of observational studies. Searches of PubMed/MEDLINE, EMBASE, PsycINFO, SCOPUS, and ISI Web of Science will be used to identify epidemiologica…

e12007 Background: B combined with chemotherapy (CT) significantly improves progression-free survival (PFS) and response rate (RR) vs CT alone in the first-line treatment of HER2-negative MBC. In a...
The Cultural Roots of Risk
2017
This paper discusses the story of Mary and Roger an elderly couple who opted to buy a car, but later were pressed to sell it because they were unable to absorb the costs of insurance. The world of risks does not work in the same lines in North than South. This pieces invites the discussion to what extent risk perception is not an instrument for controlling workforce in under-developing nations. The mythologies of mobility have been formulated around life in the First World. They work as ideological devices to activate certain circuits of the economy, which in other times were relegated to peripheral positions. The industries of tourism and air travel transport millions travelers who enjoy t…
