Advances in Engineering Research. Volume 47 e-bog

This volume includes six chapters, each of which provides updates in the field of engineering research. Chapter One reviews how cognitive radio schemes such as spectrum pooling among others improve the use of millimeter waves in mobile networks. Chapter Two introduces coupling theory and exhibits two manipulation methods for array antennas. Chapter Three describes a hardware implementation of a Simplified Gabor Wavelet transform-based approach for edge detection in image processing. Chapter Four presents a model of using multiple factor analysis and grouping to estimate the disparities in crop production development among different regions. Chapter Five models a cybernetic attack using colored petri nets to modify and delay the transmission of messages. Lastly, Chapter Six presents data mining techniques applied to a road traffic accidents database in Morocco to analyze choke points and intersection types that caused previous accidents.
