Service-oriented dynamic resource configuration optimization scheme in RFID system by Jian-hua LIU, Wei-qin TONG

“…Aiming at the defect that the rate between tag and reader was not match and their resource-constrained problem in the radio frequency identification(RFID)systems,the collaboration communication context was analyzed theoretically.Service-oriented dynamic resource configuration optimization scheme of RFID system was proposed which used the component quality of service(QoS) information of tag and reader to establish closed-loop control framework and developed three control strategies to adjust QoS parameter according to the state and type of its resources.The scheme was analyzed and validated for performance through experiments.The numerical experiments results show that the optimization mechanism make throughput of RFID systems improve,use resources efficiently and reduce the energy consumption and interference of reader-to-reader.…”

Topology control scheme based on simulated annealing algorithm in wireless sensor networks by LIU Lin-feng, LIU Ye

“…In order to study the topology control scheme satisfying the requirement of lifetime objective in wireless sen-sor networks and aiming at the defect that high redundancy of connectivity or low robust of structure in traditional schemes, the desire of topology was modeled and analyzed theoretically. The model was transformed into a problem of degree-constrained minimum spanning tree ultimately, and a simulated annealing algorithm was designed to deal with the problem. …”

Research on RFID anti-collision hybrid algorithm based on discrete processing by Ping LI, Li-min SUN, Jia-ying WU, Qing FANG, Jin-yang XIE, Bo-xiang ZHOU

“…A kind of binary tree search algorithms have distinct application limitations such as high number of requests in case that a fairly large number of tags are available.A hybrid anti-collision algorithm was proposed,combining binary tree search with discrete processing.Theoretic analysis show that,different from available schemes,the algorithm essentially performs binary tree search not on a single tag,but on models which identify the property of discrete procession.The proposed algorithm fully takes the time of request into account,as well as power consumption and throughput of the system.Simulation result verifies that the algorithm achieves much better performances such as the time of request and throughput than the previous algorithms.…”

A Mixed Finite Element Formulation for the Conservative Fractional Diffusion Equations by Suxiang Yang, Huanzhen Chen

“…In this paper, by the dividing of equation, we drop the lower regularity term in the solution successfully and get a new fractional elliptic equation which has full regularity. We present a theoretical framework of mixed finite element approximation to the new fractional elliptic equation and derive the error estimates for unknown function, its derivative, and fractional-order flux. …”

Les contradictions théoriques et empiriques du modèle rifkinien de troisième révolution industrielle. L’exemple de la Région des Hauts-de-France by Christophe Beaurain, Olivier Petit, Bruno Villalba

“…In this article, we develop a critical analysis of this regional policy, linking it to a reflection on the heuristic contributions and the limits of the theoretical model proposed by Rifkin. We thus draw from the foundations of Rifkin’s argument the sources of the consensual posture of the actors of the NPC region towards mainly technological solutions to the current ecological crisis. …”

Study on the connectivity model of VANET based on 802.11p/WAVE and its application by Ye LIU, Guo-xin WU

“…Firstly,a vehicular mobility model was proposed for the freeway traffic scenarios.Then the connectivity pa-rameters of VANET,such as the connected probability between any two cars,the diameter size of connected cluster and the number of connected cluster,were analyzed.And on the basis of these,the conclusion that the location of VANET node at one time snapshot meets the gamma distribution was drawn.Furthermore,a VANET message package format considering flooding message number was designed,in which TTL field was discussed in detail by introducing the ana-lytic expression of connectivity model.Finally,simulations also verify the conclusion.The connectivity model proposed should provide an important theoretical basis for the upper-level protocols of VANET WAVE stack.…”

Anti-frequency-shift packet detection for D2D power-saving communications over Wi-Fi network by Fan YANG, Xi LIANG, Ke-yu LONG, Li JIANG

“…An efficient packet detection scheme based on Wi-Fi interface was proposed.It was implemented by employing a novel normalized factor as a denominator in OFDM symbol synchronization-timing metric.Compared to the old-tradition schemes,the proposed scheme can not only obtain great detection probability,but also achieve the threshold setting without pre-estimation of frequency offset.Both theoretical analysis and conducted simulation results show that the new scheme facilitates threshold selection for a wide range of signal-to-noise ratio (SNR) in additive white Gaussian noise (AWGN) channel.Besides,the threshold setting in multi-path Rayleigh fading channels can be determined according to the AWGN case straight forwardly.…”

Faut-il se souvenir du républicanisme anglais ? L’héritage intellectuel du républicanisme anglais dans le temps long by Myriam-Isabelle Ducrocq

“…However, if one considers its intellectual origins, the abundance of theoretical debate at the time of the First English Revolution, the importance of its reception across the British Isles, Europe and America and the manifest or subterranean role it played in transatlantic revolutions and its legacies, it appears as a legitimate object of study for historians of political thought; which is why there has been sustained interest in the history of this intellectual tradition over the past few decades.…”
