The charged system search (CSS) algorithm is utilized for design of frame structures. The algorithm is inspired by the laws in physics. The CSS utilizes a number of charged particles which influence each other based on their fitness values and their separation distances considering the governing law of Coulomb. A comparison between the characteristics of the CSS algorithm and other well-known meta-heuristics is performed to indicate their similarities and differences. Some benchmark frame examples are optimized with the CSS algorithm. Comparison of the results of CSS with some other meta-heuristicalgorithms shows the robustness of the new algorithm.

Job shop scheduling belongs to the large class of NP-complete (nondeterministic polynomial time complete) problems and the complexity of job shop scheduling characterizes many real-life situations. In auto blanking plant, intelligent scheduling system is needed to deal with the automation of production. The core structure of job shop scheduling system is designed. The scheduling rules such as mission-critical priority rule, first come first serve rule, the highest task priority rule and the urgent tasks priority rule are built with the definitions of express tasks, urgent tasks, middle urgent tasks and normal tasks according to the time features of tasks. The heuristic optimization algorithm is designed to follow the above rules. The intelligent logistics management system is built to optimize job shop scheduling in auto blanking plant.

Barrel vaults are attractive space structures that cover large area without intermediate supports. In this paper, the charged search system (CSS) optimizationalgorithm is employed for optimal design of barrel vaults. This method utilizes the governing laws of Coulomb and Gauss from electrostatics and the Newtonian law of mechanics. The results demonstrate the efficiency of the discrete CSS algorithm compared to other meta-heuristicalgorithms.

A new meta-heuristic optimization algorithm is presented for design of skeletal structures. The algorithm is inspired by the Coulomb and Gauss's laws of electrostatics in physics, and it is called charged system search (CSS). CSS utilizes a number of charged particle (CP) which affects each other based on their fitness values and separation distances considering the governing laws of Coulomb and Gauss from electrical physics and the governing laws of motion from the Newtonian mechanics. Some truss and frame structures are optimized with the CSS algorithm. Comparison of the results of the CSS with those of other meta-heuristicalgorithms shows the robustness of the new algorithm.

Grillage systems are widely used in structures to cover large areas in bridge decks, ship hulls and floors. In this paper, the charged system search (CSS) algorithm is utilized to obtain the optimum design of grillage systems. This algorithm is inspired by the Coulomb and Gauss laws of electrostatics in physics and the governing laws of motion from Newtonian mechanics. The cross-sectional properties of beams are considered as the design variables. Comparison of the results with those of some previous studies shows the robustness of the new algorithm.

Biomedical image registration and fusion are usually scene dependent, and require intensive computational effort. A novel automated approach of feature-based control point detection and area-based registration and fusion of retinal images has been successfully designed and developed. The new algorithm, which is reliable and time-efficient, has an automatic adaptation from frame to frame with few tunable threshold parameters. The reference and the to-be-registered images are from two different modalities, i. e. angiogram grayscale images and fundus color images. The relative study of retinal images enhances the information on the fundus image by superimposing information contained in the angiogram image. Through the thesis research, two new contributions have been made to the biomedical image registration and fusion area. The first contribution is the automatic control point detection at the global direction change pixels using adaptive exploratory algorithm. Shape similarity criteria are employed to match the control points. The second contribution is the heuristic optimization algorithm that maximizes Mutual-Pixel-Count (MPC) objective function. The initially selected control points are adjusted during the optimization at the sub-pixel level. A global maxima equivalent result is achieved by calculating MPC local maxima with an efficient computation cost. The iteration stops either when MPC reaches the maximum value, or when the maximum allowable loop count is reached. To our knowledge, it is the first time that the MPC concept has been introduced into biomedical image fusion area as the measurement criteria for fusion accuracy. The fusion image is generated based on the current control point coordinates when the iteration stops. The comparative study of the presented automatic registration and fusion scheme against Centerline Control Point Detection algorithm, Genetic algorithm, RMSE objective function, and other existing data fusion approaches has shown the advant
