In this paper we establish a general swarm model with time delays under disturbances for the quadratic attractant/repellant profiles. It is proved that the swarm members will converge and form a cohesive cluster around the center in a finite time under certain conditions in the presence of communication delays and disturbances. For quadratic attractant/repellant profiles, all the swarm members will...
The auto-compensation and harmonic shielding converter transformer, namely the new converter transformer, adopts the prolonged delta wiring in the secondary winding, and there is a tap between the common winding and the prolonged winding, which is connected with the inductive filters. Compared with the traditional converter transformer, the electrical connection in the new converter transformer is...
This study investigated how different dimensions of social capital influenced employee creativity and when the effects were stronger with a heterogeneous sample of teams in the PRC. Considering knowledge as the foundation of employee creativity, we integrated the mediating role of knowledge sharing and the moderating role of knowledge characteristics in the relationship between social capital and...
This paper considers an M-member "individual-based" continuous time swarm model with individuals moving with a nutrient profile (or an attractant/repellent) in an n- dimensional space. It is proved that the swarm members aggregate and eventually form a cohesive cluster of finite size for Gaussian Profiles. Moreover, all the swarm members will converge to more favorable areas of the Gaussian...
The accuracy of detecting intrusions within an intrusion detection network (IDN) depends on the efficiency of collaboration between the peer intrusion detection systems (IDSes) as well as the security itself of the IDN against insider threats. In this paper, we study host-based IDNs and introduce a Dirichlet-based model to measure the level of trustworthiness among peer IDSes according to their mutual...
This paper considers an M-member "individual-based" continuous time swarm model with individuals that moving with a nutrient profile (or an attractant/repellent) in an n-dimensional space. The swarm behavior is a result of a balance between inter-individual interplays as well as the interplays of the swarm agents with their environment. It is proved that the swarm members aggregate and eventually...
In this paper, based on 16-day 250 m MODIS product suits, using residual trend method, the effects of Restoring Grazing to Grassland Project in Maqu grassland was evaluated. Firstly, some regression models between NDVI in different stage and synchronous meteorological data were constructed. Then using above models we can predict NDVI value without the project and analyze the residual trend of actual...
