Le problème du chargement de marchandises dans un avion cargo est soumis à des contraintes strictes de sécurité. C’est un problème d’optimisation combinatoire d’une importance cruciale pour les compagnies aériennes. En effet, un mauvais chargement diminue l’efficacité d’un avion et impose des tensions importantes sur sa structure qui peuvent entraîner la destruction d’équipements de haute valeur, voire la perte de vies. De plus, certains colis spéciaux ont des contraintes très restrictives. C’est le cas notamment des produits dangereux, des animaux, des marchandises alimentaires et périssables. En plus des incompatibilités entre certains produits, il faut tenir compte des interactions possibles sur des équipements de l’avion. Par exemple, des produits émettant des émissions magnétiques doivent être placés de manière à ne pas avoir des effets néfastes avec les instruments de navigation. Dans cet article, nous proposons d’incorporer ces contraintes liées aux colis nécessitant des précautions particulières dans un programme d’optimisation linéaire mixte du problème de chargement d’un ensemble de Unit Loading Devices et de vrac dans un avion. Les résultats obtenus à partir de données réelles montrent que notre méthode permet d’obtenir des solutions optimales en seulement quelques secondes. [less ▲]

Deciding whether a set of three dimensional boxes can be packed into a container is a NP-hard problem. Mathematical models have been developed, however, only few studies take into account constraints encountered in real-world applications such as the stability or the fragility of the cargo. Moreover, despite the importance of this issue in air transport, the literature is almost silent on constraints related to the distribution of the weight inside a container. This paper is concerned with the formulation of the three dimensional palletization which includes the main constraints met in the air cargo industry. [less ▲]

Une enquête en ligne de 72 questions relatives aux modalités pratiques habituelles de réalisation d’une césarienne a été conduite auprès de 708 vétérinaires de France, Wallonie, Pays-Bas et Suisse. Ce second article, qui fait suite au premier volet publié dans le Bulletin des GTV d’avril 2011 (n° 59), concerne plus spécifiquement les étapes de la césarienne depuis l’incision de la paroi abdominale jusqu’à sa suture, ainsi que les traitements pharmacologiques mis en place et les conséquences le plus souvent observées. Les résultats de cette enquête ont permis de constater la diversité des pratiques, mais également le fait qu’un certain nombre d’entre elles s’écartent des recommandations académiques ou bibliographiques habituelles. Ils concernent les avis exprimés par les vétérinaires et ne sont donc pas rapportés au nombre de césariennes réalisées. [less ▲]

Design and method : Office blood pressure (OBP) and home BP (HBP) were measured in 70 kidney transplant patients (KT) (43 men/27 women;KT>1 year), all were treated with antihypertensive drugs (mean number: 2±1). Mean age: 56±11 years, mean graft survival: 7±6.6 years, mean GFR: 65.6±24 ml/min, diabetes:27% and current smoking:11.5%. HBP (Omron M6) was measured during 7 days following the OBP measurement, mean HBP was calculated from day 2 to day 7. Uncontrolled BP was defined by OBP>=140-90 (>=130-80 when diabetes) and HBP>=135-85 (>=130-80 when diabetes). The day of the OBP measurement and the last day of HBP, patients collected 24h- urine and recorded at the same time their food and beverage consumption. Sodium and potassium were measured in urines and their intakes were quantified through food records. Urinary and diet Na+, K+ did not differ between the two urine collections 7 days apart. Results: 16 patients(23%) had controlled BP (OBP and HBP) while 34 (49%) remained with sustained hypertension (SHT) despite treatment, 14 (20%) had masked uncontrolled hypertension (MHT, OBP<140-90 and HBP>=135-85,130-80 if diabetes for both).When comparing the controlled and SHT, no differences were found with age, graft survival, BMI, GFR, calcineurin inhibitors or number and type of antihypertensive drugs. The groups did not differ by their sodium excretion (154±93 vs 162±88 mmol/24h) but well by their K excretion significantly higher in controlled patients (68±17 vs 53±20 mmol/24h,p=0.018) giving a Na/K ratio higher in SHT (3.2±1.3 vs2.2±1.2,p=0.03). Diet analysis showed significantly higher intakes of K (fruits, vegetables) in controlled patients (3279±753 vs 2208±720 mg/24h,p=0.010) whereas both groups consumed on average 9 g/24h of salt. When controlled for age, BMI and Na excretion, Home systolic BP was inversely and significantly correlated with urinary potassium (- 0.46;P=0.002) while no correlation was found with urinary Na.Conclusions: KT patients remaining hypertensive and well controlled patients had both high salt consumption. However, well controlled patients differed by significant higher potassium intakes and excretion. Urinary Na/K ratio could be a useful tool contributing to an optimal BP control in KT patients. However, impact of increasing potassium intakes on uncontrolled BP in KT has to be validated by prospective randomized studies [less ▲]

The preliminary ideation phase, determining more than 70 % of a project’s total costs, is a crucial part of the design process. It usually gathers several actors around the innovative solving process of a complex problem : it merges their complementary expertise, the use of mediating objects as well as a mysterious part of creativity in order to reach a solution if not innovative, at least satisfactory. With the introduction of always more powerful Computer Aided Design tools, industrial design sees its every-day practices drastically evolving : these software still not support designers during their preliminary design phases and free-hand sketches, on the other hand, encounter increasing difficulties to meet today time-to-market pressures. This thesis analyzes free-hand sketches’ and CAD tools’ respective and complementary strengths as supports to preliminary design phases. Advanced design engineering concepts, nurturing the study of the particular articulation existing between both mediating objects, are associated with dedicated Human Factors methodologies for the analysis of every-day professional practices. The research project draws its main qualitative and quantitative results from three field studies and two experimentations, bringing together more than forty professional designers and three design companies. Its multi-disciplinary approach leads to models and recommendations that directly nurture the definition of a new design support system. The specifications tend to respect, augment or, on the contrary, reject some aspects of these mediating objects and aim at supporting a design process always in respect with designers’ constraints and real needs. Beyond the concepts of our support system, we discuss some results that are of interest for communities of design engineering and human-computer interaction. Among these results are : - the extension of the preliminary design phase’s boarders ; - the non-dichotomous approach of rough and detailed mediating objects ; - the coexistence of two design moves : in addition to Schön’s «see-transform-see» theory, the externalization of a strong mental image or a strong pre-inventive form explains the early uses of CAD tools ; - the study of tool’s uses and misuses and graphic and semantic contents of external representations all along the design process, reintroduced in a simplified four-steps model ; the study of shifts occurring between 2D and 3D representations and their implications for the system’s automatization ; - and, at the strokes’ scale, the study of the exploitable key-features and the strokes’ cycles and their implications for the temporality of assistance. The thesis also discusses the added-value of its theoretical and methodological background for the materialization of a design-engineering community that articulates designer, mediating objects, design process and end-users in a coherent system, sound basis for the specification of adapted and adopted design support systems.

This thesis is about the impact of land conversion for industrialization on household livelihood strategies in Hung Yen province, northern Vietnam. The study shows that land conversion is generating a household landholdings decline while boosting the land market. After land conversion, 16% of laborers in the surveyed households find employment in industrial factories while 52% find jobs in the informal sector. Because of land conversion, rather than being net food producers, peasant households have become net food purchasers. Meantime, food safety in industrial areas is threatened by increasing environmental pollution. The findings also demonstrate that 51.9% of the surveyed households choose diversification as a livelihood strategy while 35.6% of them shift entirely to non-farm strategies. Among the affected peasant groups, households with a non-farm background that lost less than 50% of their agricultural land are likely to be in a better position to engage in lucrative non-farm jobs. Land conversion is causing a complex agrarian transformation in Vietnam. On the one hand, it generates a mechanism of social differentiation which is determined by land alteration and capital accumulation from high earning non-farm activities. On the other hand, peasant livelihood strategies, thanks to adaptation and innovation, have mitigated the impacts of land conversion and reveal the persistence of a peasant economy. [less ▲]
