A dual-arm robotic manipulator needs to maintain its end-effectors’ orientations with reference to each other as defined by the task constraints at various locations. To give one example, the task of operating a pair of pliers by rigidly grasping its handles will require that the orientation of the two end-effectors with respect to each other should vary as a function of their respective locati...

This paper compares the often-criticized "selling orientation" or "selling concept" with the commonly-praised "societal marketing concept "from the perspectives of consumer rationality and persuasibility. It is suggested that both orientations view consumers as relatively irrational and as easily prone to manipulation by marketers. The implications of this similarity are explored from the persp...

This research investigates the technique of image subtraction to find the discrepancy between healthy and illness MRI images. The technique developed in this research moves the healthy MRI image to overlap with the illness MRI image. Then, the two MRI images are aligned to the same orientation. After the healthy MRI image is overlapped with the illness MRI image, the illness MRI image is subtra...
