This paper mainly studies the optimal quantity, distribution model. defined working mechanism of cooperation between SSA UAV and radio relay UAV.  We according to distance relationship different latitude longitude on earth, we use discretization process a large number data points which are used as discrete ignition points. The shortest weighted EOC each point is obtained by Matlab software simu...

The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which f...

Aging has negative effects on motor and cognitive functions, therefore finding appropriate strategies to prevent the decline of these functions is necessary. It seems that cardiovascular fitness obtained by aerobic activity is a physiological mediator that explains the relationship between physical activity and improved cognitive performance. The aim of this research was to assess the effect...

The current study examines whether there are differences in academic success between classroom learning and distance further evaluates which characteristics associated with lower achievement learning, contrast to a setting. A cross-sectional design was employed 118 students higher education who completed the Behavior Rating Inventory of Executive Functioning–Adult Version, Self-Efficacy Questio...

Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...

Maximum nonlinear functions F : F2m → F2m are widely used in cryptography because the coordinate functions Fβ(x) := tr(βF (x)), β ∈ F ∗ 2m, have large distance to linear functions. More precisely, the Hamming distance to the characteristic functions of hyperplanes is large. One class of maximum nonlinear functions are the Gold power functions x2 k+1, gcd(k,m) = 1. We characterize these function...

Bent functions have maximal minimum distance to the set of affine functions. In other words, they achieve the maximal minimum distance to all the coordinate functions of affine monomials. In this paper we introduce a new class of bent functions which we call hyper-bent functions. Functions within this class achieve the maximal minimum distance to all the coordinate functions of all bijective mo...
