Managing the variability of biomechanical characteristics before the preliminary design stage of a medical device
No full textThe very high level of requirements for certification procedures often limit research and development departments to innovate using increments and iterations during the design process for medical devices (MD). Instead of this semi-empirical approach, a structured procedure, a breakthrough innovation should be used when designing an articular MD (prosthesis, implant). The search for concepts can be based on functional analysis and producing behavioural models of the joint in its natural state and/or equipped with the prosthesis. This paper shows how anatomical variables can be managed and integrated using a modular design approach.This study has been realized under the two joint action projects PESSOA 14630YA and PTDC/EME-PME/112977
Migration, violence and welfare programmes in rural Colombia
No full textThis paper studies migration decisions of very poor households in an environment with a high level of violence. By matching detailed retrospective data on violence levels in Colombian rural municipalities with a household survey collected for the evaluation of the "Familias en Acción" welfare programme, the empirical analysis takes into account possible selection problems of the sample and the key issue of endogeneity of violence. The main results show that high levels of violence encourage households to leave their municipality of residence but that welfare programmes may mitigate these flows, provided that the incidence of violence is not unduly high. This is consistent with the fact that the households under study are liquidity constrained: when violence is high, cash transfers may enable them to leave their municipality of residence, whereas, in more normal circumstances, receiving cash transfers increases the benefits to stay where they are registered. Further evidence using household shocks and wealth confirm that liquidity constraints play a large role in explaining such heterogeneous impacts of the programme along violence levels. Other important determinants of migration are the type of property rights and the health insurance rural households can benefit from.migration, welfare programme, violence, displacement, Colombia
Food and Cash Transfers: Evidence from Colombia
No full textWe study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total consumption and for the price variability across villages, our estimates imply that an increase in consumption by 10% would lead to a decrease of 1% in the share of food. However, quasi-experimental estimates of the impact of the programme show that the share of food increases. This result is not inconsistent with the hypothesis that the programme could increase the bargaining power of women, inducing a more than proportional increase in food consumption
Alice Mesnard: Health Risks and Migration
No full text<p>The Population and Poverty (PopPov) Research Network brings together researchers who are examining how population dynamics affect economic outcomes, primarily in African countries. The overarching vision is one of a Network where results, methodological advances, and policy impacts are shared across research teams and eventually translated into policy recommendations.</p>
<p>In this video, Alice Mesnard of City University London describes her research on health risks and migration, a rarely studied topic despite their important consequences for the planning, targeting, and effectiveness of health policies. This research investigates the role of migration in dealing with the risks of chronic and acute illnesses, injuries, hospitalizations, and communicable diseases that may not only affect the health of people but also their economic situation.</p>
<p>PRB informs people around the world about population, health and the environment, and empowers them to use that information to advance the well-being of current and future generations. Find out more about PRB at our website, www.prb.org.</p

Hommage à Jean Mesnard
No full textJeudi 19 janvier 2012, dans la salle grandiose du « Coro di Notte » du Monastère des Bénédictines, Université de Catane, il a été présenté le volume de Jean Mesnard, « Sui Pensieri di Pascal » (Éditeur Morcelliana, Brescia 2011), qui, grâce à l’éditrice Maria Vita Romeo (Université de Catane), offre la première traduction italienne d'une œuvre précieuse du grand pascalien français. Une occasion très favorable donc, pour présenter au vaste public des spécialistes et des étudiants de l'Universi..
AeroPython: classical aerodynamics of potential flow using Python
No full textThe AeroPython series of lessons is the core of a university course (Aerodynamics-Hydrodynamics, MAE-6226) by Prof. Lorena A. Barba at the George Washington University. The first version ran in Spring 2014 and these Jupyter Notebooks were prepared for that class, with assistance from Barba-group PhD student Olivier Mesnard. In Spring 2015, we revised and extended the collection, adding student assignments to strengthen the learning experience. The course is also supported by an open learning space in the GW SEAS Open edX platform.Cite as:Barba, Lorena A., Mesnard, Olivier (2019).

cTI: a Constraint-Based Termination Inference Tool for ISO-Prolog
No full textWe present cTI, the first system for universal left-termination inference of logic programs. Termination inference generalizes termination analysis and checking. Traditionally, a termination analyzer tries to prove that a given class of queries terminates. This class must be provided to the system, for instance by means of user annotations. Moreover, the analysis must be redone every time the class of queries of interest is updated. Termination inference, in contrast, requires neither user annotations nor recomputation. In this approach, terminating classes for all predicates are inferred at once. We describe the architecture of cTI and report an extensive experimental evaluation of the system covering many classical examples from the logic programming termination literature and several Prolog programs of respectable size and complexity
Response to Lombardi and Mesnard
No full textWe write to acknowledge the recent correspondence by Lombardi and Mesnard (2023) and thank them for their positive comments regarding the quality, importance, and novelty of our work. 1 We concur that economic evaluation studies from a wide variety of jurisdictions and health systems are very much needed
