Multi-Objective Decision Making Optimization of a Residential Net Zero Energy Building in Cold Climate
No full textInternational audienceThe challenge in Zero energy building (ZEB) design is to find the best combination of design strategies that would face the energy performance problems of a particular building. This paper outlines the methodology and the cost-effectiveness potential for optimizing the design of net-zero energy building (NZEB) in a cold climate region in Lebanon; Cedars. Specifically, the non-sorting genetic algorithm (NSGA-II) is chosen in order to minimize thermal, electrical demands and life cycle cost (LCC) while reaching the net zero energy balance; and thus getting the Pareto-front. A ranking decision making technique (ELECTRE III) is applied to the Pareto-front so as to obtain one optimal solution. A wide range of energy efficiency measures are investigated, besides solar energy systems are employed to produce required electricity and hot water for domestic purposes. The results clearly indicate that, for designing a residential NZEB in cold climate, it is essential to minimize the space thermal load through a building envelope with high thermal performance. Envelop high level of insulation is an essential step to decrease the high heating demand. Building thermal loads are decreased by 33.19%. Moreover the LCC is decreased by 31.09%
Optimal Deterrence of Cooperation
No full textInternational audienceWe introduce axiomatically a new solution concept for cooperative games with transferable utility inspired by the core. While core solution concepts have investigated the sustainability of cooperation among players, our solution concept, called contraction core, focuses on the deterrence of cooperation. The main interest of the contraction core is to provide a monetary measure of the robustness of cooperation into the grand coalition. We motivate this concept by providing optimal fine imposed by competition authorities for the dismantling of cartels in oligopolistic markets. We characterize the contraction core on the set of balanced cooperative games with transferable utility by four axioms: the two classic axioms of non-emptiness and individual rationality, a superadditivity principle and a new axiom of consistency

A practical and efficient asymptotic coarse-graining model for the elastohydrodynamics of slender-rods and filaments
No full textThe inertialess fluid-structure interaction of active and passive inextensible filaments and slender-rods are central in many processes in nature, from the dynamics of semi-flexible polymers to cy-toskeletal filaments, flagella and artificial swimmers, covering a wide range of scales. The nonlinear coupling between the geometry of deformation and the physical effects invariably result on intricate governing equations that negotiate elastohydrodynamical interactions with non-holonomic constraints, as a direct consequence of the filament inextensibility. This triggers numerical instabili-ties and require penalization methods and high-order spatiotemporal propagators. Here, we exploit the the momentum balance in the asymptotic limit of small rod-like elements which are integrated semi-analytically. This bypasses the nonlinearities arising via the inextensibilty constraint, avoiding in this way the need of Langrange multipliers. The equivalence between the continuous and asymp-totic model allows a direct comparison between the two formalisms. The nature of the asymptotic approximation entails that coarse discretisation is possible while having a higher precision when compared with the continuous approach. We show that the asymptotic model is also numerically stable in situations in which the continuous formalism has a very poor performance, while the coarse structure guarantees faster computations, over than a hundred times faster than previous schemes. The asymptotic model is simple and intuitive to implement, and generalisations for complex interaction of multiple rods, Brownian polymer dynamics, active filaments and non-local hydrodynamics are straightforward. We demonstrate these via four exemplars: transient dynamics, force-displacement buckling instability, magnetic artificial swimmer and cross-linked filament-bundle dynamics, and we additionally provide the Matlab codes

Simple Length Rigidity for Hitchin Representations
No full text48 pages, 7 figuresWe show that a Hitchin representation is determined by the spectral radii of the images of simple, non-separating closed curves. As a consequence, we classify isometries of the intersection function on Hitchin components of dimension 3 and on the self-dual Hitchin components in all dimensions
