This paper presents a synthesis design of the manipulating indicator signal based on the optimal control theory, which is verified to be effective in improving tracking performance and reducing operator's work-load through simulating test.
Through researching the optimal pilot control model, the optimal control/display cooperative synthesis design and the preview quickening signal display, a optimal pilot preview control model for aim tracking and predictive control pilot machine structure are built by using optimal digital preview control and predictive control techniques.
This paper discusses the present situation about ultra black and quick setting acrylic amino-resin top-coat specially used for bicycles and introduces the proportion of amino-resin to acrylic resin during the top coat design as well as the synthetic design,the construction of the top coat,the film quality and its applications.
Methods: 1. 21-mer oligodexynucleotides targeted against the translation initiation of EF-1A2 mRNA and complementary-sense control oligonucleotides were synthesized from shanghai sangon and 3 bases each two ends were phosphorothioate.
Discussing the effect of solvents with different dielectric constants on IR spectrum, and comparing with 'HNMR and IR spectrum of compounded products of poly (ethyl methacrylate) and poly (ethyl a-cyanoacrylates), the result indicates, calculated IR spectrum on the level of B3LYP/6-311G* basically (not correcting) accord with experiment result, proves vibration analysis research of this theory is reliable, and is important to design of compounding high polymer.
These hierarchical relations serve as a basis for the organization of a functional group database, providing a tool for synthesis design and molecular engineering.
The novel frame designs evolved by the IRR GA synthesis design method compare favourably with traditional frame design solutions calculated by trial and error.
Work on chemical structure representation and searching, quantitative structure-activity relationships, chemometrics, molecular modeling as well as computer-assisted structure elucidation and synthesis design was initiated in the 1960s.
A hypergraph and perspective approach to organic synthesis design
Various computer programs for organic synthesis design greatly assist chemists in the task of synthesizing chemical compounds.
The paper simply introduced the functions of the nitrogen in drugs and the distributions of the functional group pairs of con-taining nitrogen in synthetic drugs, and employed the concept of cfunctional group pair from the angle of the drug design to dis-uss the pharmacologic activities of some important functional groups of containing nitrogen in the various combinations.
