Strengthening risk management and control of urban rainwater resources utilization is the key to ensuring the sustainable and efficient use of urban rainwater resources.On the basis of comprehensive research on urban rainwater utilization, the definition and connotation of urban rainwater utilization emphasizing the attributes of resource utilizati
In order to quantitatively characterize the surface physical structure of a bundle of carbon fibers, scanning electron microscope (SEM) was used to photograph the fiber section and edge differential detection method was used to automatically identify the fiber boundary.By finding the smallest circumscribed convex polygon of fiber section and the mi
This work presents a state feedback controller suitable to regulate the output voltage of DC-DC buck converters operating under input voltage disturbances and load variations.First, a state space model of the plant is given and the performance requirements are presented, in terms of bounds on rejection of disturbances, bounds on settling time of tr
Systems of deterministic finite automata communicating by sending their states upon request are viseart etendu cashmerie investigated, when the amount of communication is restricted.The computational power and decidability properties are studied for the case of returning centralized systems, when the number of necessary communications during the co
