We design an intelligent optimization system about the response of a traffic signal response, based on a research on traffic at various periods of Wuhan. Fedded traffic flow on the road monitored back to the SCM control system. On the basis of the existing traffic control devices, produce a new intelligent traffic lights according to the traffic flow to change the access time. And optimize the design through modeling and calculation. After simulation, the system significantly reduces the waiting time of the automobile, relieves the burden of traffic at its peak, and eases the pressure on energy and the environment.
We propose a reversed-phase high-performance liquid chromatographic method using fluorescence detection for the determination of residual levels of bisphenols A and F in noncured epoxy resins prepared under various conditions. This method optimizes the conditions of synthesis of bisphenol diglycidyl ether epoxy resins so that migration of these monomers from materials that will come into contact with foodstuffs falls within legal limits. The method is sensitive, as proven by the high slopes of the calibration lines; it is also free from interferences because the intercepts of the calibration lines are not significantly different than zero (α = 0.05, degrees of freedom= 6). The results are linear over a wide range of concentrations covering two orders of magnitude (from 10 to 1,000 ppb). Detection limits are about 4 ppb for bisphenol F and 6 ppb for bisphenol A. Precision along the calibration lines is revealed by the error index percentages (lower than 3.5) and determination coefficients (better than 0.997).
Quantitative genetics is the study of continuously varying traits which make up the majority of biological attributes of evolutionary and commercial interest. This book provides a much-needed up-to-date, in-depth yet accessible text for the field. In lucid language, the author guides readers through the main concepts of population and quantitative genetics and their applications. It is written to be approachable to even those without a strong mathematical background, including applied examples, a glossary of key terms, and problems and solutions to support students in grasping important theoretical developments and their relevance to real-world biology. An engaging, must-have textbook for advanced undergraduate and postgraduate students. Given its applied focus, it also equips researchers in genetics, genomics, evolutionary biology, animal and plant breeding, and conservation genetics with the understanding and tools for genetic improvement, comprehension of the genetic basis of human diseases, and conservation of biological resources.
