C-V model without re-initialization was applied to detect the stone slab contour on simple and complex background respectively. Using the flexible initial curve which is closer to the object boundary, a stable and correct segmentation can be achieved rapidly. For the simple background, this model can exactly detect the stone slab contour. While for the complex background, the result somewhere is an approximation of object contour because the object and background have nearly the same intensity. Additional work will be done to perfect the results.
The paper discusses the modified projective synchronization of two different chaotic systems by nonlinear control laws, considering the conditions of the master-slave systems with uncertain parameters, the synchronization problem between Genesio system and Rossler system has been investigated, adopting the adaptive control method, a sufficient condition is attainted for the modified projective synchronization between master and slave system, finally, The control performances are verified by the numerical examples.
In order to achieve the national energy saving targets, and track, supervise, manage and assess the energy-using condition of the key energy-using enterprise effectively, according to the user’s demand and the system feature, the Microsoft.Net framework and the MVC mode are chosen, and combined with the Ajax technology, the implemented plan is settled. The .net-based energy-saving information management system is designed and implemented, and it improves the condition of the information reporting and statistical analysis mean for key energy-using enterprise and relevant functional departments. The result shows that the system architecture is reasonable, and it improves the maintainability and extendibility of the system.
The residue sulfate ions (SO42-) occurs in an adsorption and complex salt manner which are significant influence the electrochemical properties of LiNi1/3Co1/3Mn1/3O2 as cathodes materials for lithium-ion batteries. Compare with different SO42- concentration electrochemical performance reveals that low SO42- concentration (0.28%) demonstrated a better charge/discharge cycle performance than the high SO42- concentration (0.48%) of LiNi1/3Co1/3Mn1/3O2, it maintains a capacity of 148.9 mAh·g−1 with a coulomb efficient of 91 % after 100 cycles which superior to the SO42- concentration (0.48%) circulation coulomb efficient of 87%, respectively.
Soil liquefaction is extremely detrimental to the Central Henan transit railway line project. The present study proposes a preliminary design to evaluate the effects of liquefaction and to determine the parameters and protective measures that need to be implemented. The geological properties, clay content, groundwater level, and the thickness of the overlying non-liquefied soil were initially determined. Then, a standard penetration test was employed to analyse the soil liquefaction potential in an iron mine in the Central Henan rail transport project. The evaluation of similar engineering project sites with middle-class areas vulnerable to liquefaction is important to determine the necessary anti-liquefaction measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
