two main factors influencing the entrepreneurial opportunity recognition, i.e. prior knowledge and cognitive characteristics have been identified. in order to examine the effect of prior knowledge on opportunity recognition with mediating role of cognitive characteristics including entrepreneurial alertness and entrepreneurial learning, the conceptual model of research and the related hypothese...

background: alpha methyldopa (amd) is a well-known treatment for the pregnancy induced hypertension and commonly used in several countries. indeed the possible effect of amd on the behavioral activities of offspring, whom are exposed during fetus period, has not been studied. the present study evaluated the possible effect of maternal administration of amd on the rat offspring memory in the gro...

Comparing experts with novices offers unique insights into the functioning of cognition, based on the maximization of individual differences. Here we used this expertise approach to disentangle the mechanisms and neural basis behind two processes that contribute to everyday expertise: object and pattern recognition. We compared chess experts and novices performing chess-related and -unrelated (...

The development of handwriting character recognition (HCR) is an interesting area in pattern recognition. HCR is the ability of a computer to receive and interpret intelligible handwritten input such as digital cameras and other devices. HCR system consists of a number of stages which are preprocessing, feature extraction, classification and followed by the actual recognition. Handwritten can b...

statistical process control (spc) charts play a major role in quality control systems, and their correct interpretation leads to discovering probable irregularities and errors of the production system. in this regard, various artificial neural networks have been developed to identify mainly singular patterns of spc charts, while having drawbacks in handling multiple concurrent patterns. in this...

in this research work, the frequency domain (fd) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. in order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and blind mineralization using the surface geochemical data for the dalli cu-au porphyry deposit, a ...

In pattern recognition, it is often necessary to deal with problems to classify a transformed pattern. A neural pattern recognition system which is insensitive to rotation of input pattern by various degrees is proposed. The system consists of a fixed invariance network with many slabs and a trainable multilayered network. The system was used in a rotation-invariant coin recognition problem to ...
