This paper focuses on a single crane scheduling problem in order to pick all demanded coils for downstream stage production or for customer which is motivated by cooled-rolling material warehouse in the iron and steel enterprise. If a demanded coil is in the upper level, it can be picked up directly to designated place (transportation operation). If a(More)
The blurring in image comes either from the acquisition noise, or from image editing operation. The produced adverse noise during acquisition need to be eliminated, and the blurring generated by editing should be known in digital forensics, so the blur kernel recovery is significant in community of image processing and computer graphics. In the log-fourier(More)
For designing wireless sensor networks, the coverage of the sensing area, sink location and data routing are three major issues. This paper considers three technique problems within a unified framework and develops a mixed-integer linear programming formulation. Further, a hybrid meta-heuristics is proposed to solve the solution. The outer loop of this(More)
