Developments of Mathematical-Physical Biology, Matrix Mechanics in Pharmacology, and Medicine with Time Sequences

First, some mathematical and physical developments of biology and medicine are discussed, including biofield and biological electromagnetics. Second, we research nonlinear biology and biotopology, in which some knots may describe the protein folding. Third, symbolic dynamics of biology and the extensive quantum biology are researched. Fourth, we study the biothermodynamics and entropy. In thermodynamics of pharmacology, the main effects of various drugs are to promote internal interactions in body, and entropy decrease. Further, we introduce the diagnostic space, treatment space and some medicinal vectors, and propose the matrix mechanics of pharmacology. Finally, we research biology, medicine and pharmacology with time sequences. If we master the medication time, this will be able to get the minimum amount of medication, and the drugs can play the maximum treatment effect. If period is accurate, it can determine the time of play, negotiations, attack, etc. But, period of each individual should be change follow age, etc. This is a very valuable research.

Event-Triggered Control and Application for A Class of Nonlinear Multi-Agent Systems With Time Delay

Linear multi-agent systems (MAS) have been studied a lot. Since nonlinear MAS with time delay and directed graph by using the event-triggered technique are seldom studied, the distributed control of a class of nonlinear leader-following MAS is considered in this paper. Firstly, we linearize the nonlinear MAS composed of N agents with directed graph by feedback, and transform the research object into a linear system. Furthermore, we proposed an event-triggered consensus algorithm for the leader-following MAS. Then we prove the consensus of the proposed algorithm by using related theorems. It is proved that the algorithm converges exponentially and avoids Zeno-behavior of triggering time sequences. Finally, we apply the designed event-triggered consensus algorithm to an engineering example. A simulation system is established in Matlab environment and the simulation example results verify the effectiveness of the proposed algorithm. It effectively reduces the number of communication among agents and achieves the consistency of control objectives.

Comparison Sequences of Pick and Place System Controlled Using PLC

Pick and place system is one of the significant employments of modern robots utilized in industrial environments. The objective of this research is to make a comparison of time sequences by combining multiple axes of sequences. A pick-place system implemented with pneumatic linear double-acting cylinders to applicator in automated systems processes for manufacturing. The challenge of 3-axes movement control was achieved using the PLC (Programmable Logic Controller) controller such that the merging between two or three axes was achieved according to the selected sequence of the program. The outcomes show the contrasted sequences and the reference in a constant velocity. The main variable parameter is the number of steps for each sequence. The combination of two axes has developed the sequence and reduced in number of sequences for a path. At last, one of the important factors in moving products industry is the smooth product’s movement, because any high speed might cause a vibration in the system and lead to a decreased positioning accuracy.
