This working paper is divided into two parts. The first part provides a reminder and theoritical background in fluid thermodynamics (first law, second law, ideal/real gases, liquids, thermodynamic processes). The second part applies the theory to the study of a simple Organic Rankine Cycle, by modeling the 4 main processes (pumping, evaporation, expansion, condensation). [less ▲]

Cet article porte sur la traduction intersémiotique d’un concept lié au langage verbal, le soliloque, en langage visuel et notamment photographique. À ce propos, on s’interroge sur les stratégies méta-textuelles utilisées par l’image photographique afin de mettre en scène un acte intime d’introspection. L’un des thèmes fondamentaux de cette recherche est l’intertextualité visuelle prise en considération à différents niveaux. J’ai étudié : 1) les rapports entre les neuf images qui composent la série des photos intitulée « Soliloquy » de Taylor-Wood (intertextualité sérielle), 2) les rapports entre cette série et d’autres travaux du même artiste (intertextualité intra-poétique), 3) les rapports entre ladite série et des œuvres picturales explicitement citées et revisitées par Taylor-Wood (intertextualité inter-poétique), 4) la relation entre la configuration spatiale des « soliloques » photographiques et le retable ancien, relation qui montre les déformations axiologiques que ce dernier a subi (intertextualité de genre).

Water availability for agricultural activities will decrease in the twenty-first century. As a consequence, agricultural water management will have to improve in order to meet two challenges: satisfy the needs of an increasing world population; and alleviate the climate change impacts. One way to improve agricultural water management consists of including the ‘risk’ notion as much as possible at the different decision levels of: farmers, farmer corporations and states or associations of states. These three decision levels will be analysed both for rainfed and irrigated agriculture. The poorest countries are those most subject to climate risks, the main risks in developing countries, because they too rarely possess the means to combat excesses or shortages of water during the plant growing period (irrigation schemes) and they cannot rely on crop insurance or other kinds of support to maintain their income in bad years. Consequently, in order to ensure a minimum level of income, farmers will prefer low input practices that provide a low but stable production without involving too much investment or cash. Where possible they will diversify their production. This paper first defines hazard, vulnerability and risk in the particular context of drought assessment and prediction. It then presents some strategies to reduce water risk in three major categories: (1) more irrigated agricultural land in an efficient manner; (2) increased and better managed pasture and forest areas to benefit from otherwise lost water by evaporation process, increasing animal productivity; (3) well water managed dryland agriculture. In dryland agriculture, some additional public measures are necessary, mainly drought risk insurance and early warning systems, in order to promote investment in drought-prone environments and to provide tools for decision-making. The adoption of an efficient water use management of rainfall and irrigation will ensure food security, contribute to poverty alleviation, and free water for non-agricultural uses. The paper presents some new promising techniques and approaches. Finally, it discusses the sharing of risk between the different decision levels and launches some ideas to serve as discussion points in the electronic conference. [less ▲]

An extension of the (nonexact-perturbed) forward-backward method for finding a zero of a sum of two maximal monotone operators is proposed, using a nonlinear metric, tied to Bregman functions. Results of weak and strong convergence for a sequence generated by such a method are established, under similar assumptions to those appearing in the context of the proximal point algorithm.

Let H be a real Hilbert space and T be a maximal monotone operator on H. A well-known algorithm, developed by R.T. Rockafellar, for solving the problem "To find x in H such that 0 in Tx" is the proximal point algorithm. Several generalizations have been considered by several authors: introduction of a perturbation, introduction of a variable metric in the perturbed algorithm, introduction of a pseudo-metric in place of the classical regularization, ... We summarize several of these extensions by taking into account a pseudo-metric as regularization and a perturbation in an inexact version of the algorithm. [less ▲]

The variational convergence theory has known these last years a lot of developments. This theory is fundamental to give a global approach of problems which consist in searching a zero of a maximal monotone operator on a real Hilbert space. The notion of perturbation is often used in the resolution of such problems. More and more authors work also with a special or a variable metric on the space to solve this kind of problems. In the present paper, we give a unified context to couple these two approaches: a variational metric between operators, taking into account different metrics on the space. [less ▲]

We set an algorithm for the complete discretization of parabolic problems combining the finite element method for the space variables x and the discontinuous Galerkin method for the time t. By using the Legendre's polynomials in t, we reduce the resolution of the system of qN linear equations, where N is the amount of finite element degrees of freedom and q-1 is the degree of the approximations with respect to t, to two inversions of NxN matrices and one evaluation of a NxN matrix polynomial of degree q by a technic of Horner's type. The systematic character of the coefficients allows an algorithm with q as a parameter. [less ▲]
