Background: Autism Spectrum Disorder (ASD) occurs based on the continuous deficit in a person’s verbal skills, visual, auditory, touch, and social behavior. Over the last two decades, one of the most important approaches in studying brain functions in autistic persons is using functional Magnetic Resonance Imaging (fMRI). Objectives: It is common to use all brain regions in functional extracti...

In the design process of gratings, the grating layout design is the most important activity in influencing manufacturing cost. In the grating layout design, the key to saving manufacturing cost is to find a design with a minimal number of cutting operations. This paper presents an application of the A* algorithm in grating layout design. The design problem is represented as the space search pro...

ion is widely used for speeding up search. In particular, it can be beneficial in the creation of heuristic functions. For any state s in the original state space, a heuristic function estimates the distance of s to the goal. Given an abstraction, the actual distances in the abstract space can be used to define a heuristic function that never overestimates the true distances. Such heuristic fun...

Abstraction, in search, problem solving, and planning, works by replacing one state space by another (the “abstract” space) that is easier to search. The resultsion, in search, problem solving, and planning, works by replacing one state space by another (the “abstract” space) that is easier to search. The results of the search in the abstract space are used to guide search in the original space...

With rapid development in information gathering technologies and access to large amounts of data, we always require methods for data analyzing and extracting useful information from large raw dataset and data mining is an important method for solving this problem. Clustering analysis as the most commonly used function of data mining, has attracted many researchers in computer science. Because o...

Differential Global Positioning System (DGPS) provides differential corrections for a GPS receiver in order to improve the navigation solution accuracy. DGPS position signals are accurate, but very slow updates. Improving DGPS corrections prediction accuracy has received considerable attention in past decades. In this research work, the Neural Network (NN) based on the Gaussian Radial Basis Fun...
