Un écoféminisme à la française ? Les liens entre mouvements féministe et écologiste dans les années 1970 en France by Isabelle Cambourakis

“…It analyses in particular three aspects of efforts to make these movements converge: the attempts to organize meetings and coalitions between the ecologist movement and some feminists; the theoretical links proposed by Françoise d’Eaubonne from 1974 surrounding the concept of eco-feminism; and the growing interest in ecology of some differentialist feminists situated at the junction of various social movements. …”

Combinatorial double auction-based allocation of retrieval tasks in Internet of Things by Zhi-kai XU, Hong-li ZHANG, Xiang-zhan YU, Zhi-gang ZHOU

“…Task allocation mechanism was greatly important to the success of the search service in Internet of Things (IoT).On basis of analyzing the real time characteristics of the IoT data,and the dynamic characteristics of the users,a combinatorial double auction-based retrieval tasks allocation model was introduced,which described the relationships between the workers,the requesters and the system from the perspective of supply and demand.Firstly,a novel metric to evaluate the value of the users’ queries was introduced and a greedy heuristic algorithm to determine the winning requesters and workers was proposed.Then,a critical payment scheme was proposed,which guaranteed that submitted bids of the users reflect their real value.Finally,both the rigid theoretical analysis and simulation result show that the proposed mechanism achieves truthfulness,individual rationality and the efficiency of the service provider is improved.…”

Differential detection scheme for distributed MIMO systems in fast fading channel by Dong-dong DOU, Jun-bo LIU, Da-ming WANG, Zhao-xun LI

“…In the fast fading distributed MIMO system,it is difficult to keep the channel fading coefficient unchanged in adjacent space-time blocks due to the rapid changed state information,which leads to the traditional distributed MIMO differential detection scheme is not suitable any.Aiming at this matter,an improved differential detection scheme was proposed.By recombining space-time codes which were differential modulated by phase,this differential detection scheme reduced the influence from fast fading channels at the cost of larger processing delay and additional transmission power.Theoretical analysis and some computer simulation results show that this scheme can improve the BER performance remarkably in fast fading channels compared with the existing the conventional differential space time detection.…”

La haute mer : un espace aux frontières de la recherche géographique by Camille Parrain

“…The geographical approach has so far mainly been an applied geography and has focused on regional, sectorial and coastal aspects. Few are aiming at theoretical approaches or on the high seas. We will overview the position of the ocean within geography and will try to explore new research perspectives by taking into account sailing and the concept of territory in the high sea that we will define as « maritory ». …”

Tooth Contact Analysis of Profile-Shifted Face Gear with Double-Crowned Pinion by Li Wei, Wang Dan, Fu Xuezhong

“…The coordinate systems for the processing and driving of the profile-shifted spur pinion with double-crowned and the profile-shifted face gear are established,the tooth surface equations of the profile-shifted pinion and the profile-shifted face gear are deduced,while the tooth surface is simulated for visualization.The modified tooth surface is precisely represented by a sum of two vector functions that determine the theoretical tooth surface and deviation surface.The tooth contact analysis is conducted for the alignment errors of the driving system,and the tooth contact path and the transmission error are computed.The results show that it enables the transmission error to form second order parabolic function with opening down through this method,the sensitivity of contact patch for the alignment errors is reduced,and the meshing performance of profile-shifted face gear drive is improved.…”
