Applications of artificial fish school algorithm in combinatorial optimization problems
An optimizing method based on autonomous animats approach, artificial fish school algorithm, is presented. It is applied to solve the combinatorial optimization problem. The concepts of distance,…
Robot autonomous localization based on a single artificial landmark
TLDR
Based on four essential rules of how to design a landmark, a new style of landmark is proposed, that is a planar self-similar landmark based on QR code technology that can make the robot realize autonomous localization by only a single landmark.
Solving the Fixed Shelf Order-Picking Optimization Problem Using the Modified LK Algorithm
TLDR
The results of simulation indicate that the new modified Lin-Kernighan(LK) algorithm can reduce the computational complexity of time and space greatly, and can also find out the optimum solution quickly and steadily.
Parameter estimation method based-on artificial fish school algorithm
A new parameter estimation method based on artificial fish school algorithm is proposed due to its characteristics, and simulation studies are carried out. The simulation result shows that this…
Density measurement of rockfill by use of rigidity correlation method
A method to measure the density of rock fill by use of the rigidity correlation method is put forward with regard to the characteristics of the rockfill of Yanshan Reservoir.The rigidity(K),the…
Isolation and Purification of Polysaccharide from Hedyotis Difusa Wilid and Analysis on its Composition by Pre-column Derivatization HPLC
A method of preparation of polysaccharide from Oldenlandia diffusa wild was identified,using hot water extract method,ethanol precipitation,removing the proteins by TCA reagent,decoloring with…
Passive detection of scatterer using autocorrelation of surf noise
TLDR
The experimental result shows that the processing of autocorrelation could replace cross-correlation in passive target detection when the ambient noise is time steady and the statistical characteristics of the background noise at different receivers are the same.
