Traffic Driven Epidemic Spreading in Weighted Homogeneous Networks
Zinan Chang,Fei Shao 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.1
To investigate the impact of weights on the traffic driven epidemic spreading in weighted homogeneous networks, an epidemic model in pseudo-random network with adjustable weights is presented. In the scenario that epidemic pathway is defined and driven by traffic flows, the epidemic spreading velocity of SI model in weighted homogeneous networks is obviously accelerated when the edge weight is different. And in traffic driven SIS model, the epidemic threshold is found to be proportional to the inverse of the average node betweenness. It is better to control the epidemic spreading when the edges have the same weight. Simulation results have confirmed the theoretical predictions.

This work describes the separation of Ni and Co from a real feed solution in chloride media with high Ni content. The extractant used was P507 (2-ethylhexyl phosphoric acid-2-ethylhexyl ester) in a laboratory scale Impinging Stream–Rotating Packed Bed (IS-RPB) contactor. Key variables including feed solution pH, extractant concentration, saponification degree, high gravity level and total volumetric flow rate of fluids amongst other variables were examined. A McCabe–Thiele diagram of the extraction stage predicted that at a total volumetric flow rate of 90 L/h, feed solution pH of 5, saponified P507 concentration of 25% and high gravity of 83, almost 99% of cobalt, would be extracted within three stages. With regard to the scrubbing results, the co-extracted nickel was scrubbed efficiently from the loaded organic solution using a mixture of 0.02 M CoCl2 and 0.5 M hydrochloric acid solution, The purified Co solution was achieved after stripping the loaded-organic phase with 1 M HCl. The maximum value of the overall volumetric mass transfer coefficient for the IS-RPB extractor was found to be 0.16 s−1 which was superior to that of conventional extractors such as mixer-settler and centrifugal extractors, providing strong confidence for its industrial application.

Hierarchical Data Gathering Scheme for Energy Efficient Wireless Sensor Network
Jinping Chen,Zinan Chang 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.3
Compressive Data Gathering (CDG) has recently emerged to provide energy efficient data aggregation in wireless sensor networks (WSNs). Existing CDG is done by forming a span-tree from all sensors to the data sink, which leads to a lot of energy consumption in maintain this tree. In this paper, we present a clustering based CDG scheme for large-scale WSNs. This scheme reduces traditional network communication cost by introducing in-network compression and recovers sensory data accurately by using compress sensing theory. With extensive simulation, we demonstrate that our scheme prolongs nearly 45% network’s lifetime compared with the Hybrid compressive data gathering schemes.

Enhancing Transmission Capacity of Weighted Networks
Fei Shao,Zinan Chang 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.1
How to control the traffic congestion and improve the transmission capacity of weighted network is of great importance in real world networks. In some weighted networks, the weight is the geographic distance between nodes. The transmission capacity of weighted network is investigated according to different node delivery capability schemes. In the schemes that delivery capability of each node is proportional to its degree and proportional to its strength, the transmission capacity can be enhanced greatly after deleting some edges while the network integrity is still maintained. Simulations show that deleting edges according to their original weight is proved to be more effective. It is of great practical importance in designing the network topological structure.
