the main obstacle facing cancer preventive strategies worldwide is a lack of well conducted epidemiological studies to guide local and international efforts for disease control. in lebanon, long due political strain has added yet another obstacle to the development of methodologies aiming to collect data on cancer epidemiology. however, through several efforts dated from the 1960s the picture i...

Abstract. An optimal control problem for a parabolic obstacle variational inequality is considered. The obstacle in L 0; T ;H( ) \H 0 ( ) with t 2 L (Q) is taken as the control, and the solution to the obstacle problem taken as the state. The goal is to nd the optimal control so that the state is close to the desired pro le while the norm of the obstacle is not too large. Existence and necessar...

Walking and texting on the phone can be dangerous. People often hurt themselves because they do not pay attention to obstacles in their way. Fortunately most phones nowadays have an integrated back camera. This can be taken to advantage. The stream of pictures from the back camera can be analysed to recognize obstacles. This can be done by dividing the pictures into regions with similar colors....

We present work on a robot system capable of rapidly learning to avoid obstacles in previously unseen environments. We exploit deep learning’s generalized features to reason about when to turn left, turn right, or drive straight within an indoor environment. We present preliminary results of a deep convolutional neural network trained without any pre-training that can successfully avoid obstacles.
