We propose an empirical performance evaluation of six different 2D object recognition techniques. For this purpose, two novel recognition methods that we have developed with the aim to fulfill increasing industrial demands are compared to the normalized cross correlation, the sum of absolute differences, and the Hausdorff distance as three standard similarity measures in industrial applications...

chaos theory discusses unstable and non-periodic behavior of non-linear fluctuating dynamicsystems. since evaporation level variations of lakes have a dynamic identity, chaos theory can have a uniquerole in collecting data of these variations. therefore it is an important and challenging problem in the field ofplanning and qualitative and quantitative management of urmia lake to verify whether ...

This article proposes a new method to analyze the spatial structure of urban systems using ideas from fractals. Regarding a system of cities as a set of “particles” distributed randomly on a triangular lattice, we construct a spatial correlation function of cities. Suppose that the spatial correlation follows the power law. It can be proved that the correlation exponent is the second order gene...

time series. Notice the non–stationary mean and variance, especially the elevated mean during the fourth day, and the relatively quiet conditions during the later part of the fifth day. These short periods of high correlation may be leading to a spurious dimension estimate. Next we tried estimating the dimension of the attractor using the method of Termonia and Alexandrowicz (1983), but no scal...

employee empowerment is a new approach of internal motivation of job means to free internal energy of employee and also provides opportunities for them to actualize their talent, abilities and competencies. current research implemented within models of votten and kamron that implicate multi-dimensions of empowerment have four dimensions of feeling competent, feeling being meaningful, self-deter...

the main function of rural areas in the third world is the agricultural function which is crucially important because of its great effects on employment, moderating income and poverty, food security and self-efficacy. this article studies the role of agriculture (as an independent variable) in rural development (related variable) of miyankangi district in sistan. the method of the study was des...
