Experimental Study on Optimal Design of Permeable Concrete Mix Ratio
Published 2023-01-01“…This experiment aimed to develop a new type of permeable concrete with high strength,with various mix ratio designs tried.In addition,the effects of various mix ratio designs on the compressive strength and permeability performance of permeable concrete were studied,and the optimization design scheme of the optimal aggregate and mix ratio of permeable concrete was proposed.The study shows that in permeable concrete,the high-efficiency water-reducing agent is effective in assisting silica fume dispersion;the use of mechanism sand can improve the compressive strength of permeable concrete;after adding fine aggregate and admixture,the optimal water-cement ratio is 0.32;the compressive strength after 28 d is improved,and the permeability is greater than 2 mm/s;when the structural strength requirement of permeable concrete pavement is not high,or when there is special concern about pavement clogging in a longer period of use,a higher water-cement ratio of 0.36 can be used.…”

Earthquake Response Control of Double-Layer Truss Walls by means of Innovative Fuse Connections
Published 2018-01-01“…The study proposes a fuse-type connection by means of yield of the steel bolt due to tension stress realized by the ductile failure collapse mechanism of the wall-type spatial structure. The proposed truss wall with the fuse-type connection can realize a deformation of nodes within the restriction for avoiding a nonstructural member damage. …”

Pour un geste du préalable, lorsque l’intention se fait forme
Published 2011-10-01“…À travers trois dispositifs de partitions (Tool Box, projet porté par Entre deux, la Tool Box du chorégraphe Thomas Lehmenn, revue Véhicule) il sera ici question de la partition considérée non plus comme notation de l’existant, ou à suivre, mais comme processus de création.Véritable système de création, entre scénario et dispositif, les partitions artistiques et chorégraphiques donnent une nouvelle place à la structure, rendant visible ou objectivant un système préalable de création.Le geste qui persiste de l’artiste n’est plus le fruit d’une action technique spécifique, mais bien la publicité de son intention préalable, symptôme d’une éthique de la « déproduction » pour bon nombre de pratiques artistiques contemporaines.…”

Sexualité juvénile et fabrique du genre en milieu rural en Suisse
Published 2015-12-01“…Based on an ethnographic investigation of members of rural youth groups in the French-speaking part of Switzerland, this article intends to demonstrate how sexual experiences there reveal a great deal about the establishment of gender relationships. Structured around the primacy of the heterosexual norm, they push young people to identify with one sex and to internalize the forms associated with it socially. …”

Study on distributed and dynamic resource management for delay-sensitive sensor network
Published 2017-07-01“…The delay-aware dynamic resource management problem was investigated in sensor network,with a focus on resource allocation among the sensors and power control along the time.By taking account of average delay requirements and power constraints,the considered problem was formulated into a stochastic optimization problem.Inspired by Lyapunov optimization theory,the intractable stochastic optimization problem was transformed into a tractable deterministic optimization problem,which was a mixed-integer resource management problem.By exploiting the specific problem structure,the mixed-integer resource management problem was equivalently transformed into a single variable problem,and the cooperative distributed method was present to effectively solve it with guaranteed global optimality.Finally,a dynamic resource management algorithm was proposed to solve the original stochastic optimization problem.Simulation results show the performance of the proposed dynamic algorithm and reveal that there exists a fundamental tradeoff between delay requirements and power consumption.…”
