A Hough Space Feature for Vehicle Detection
2018This paper addresses the pattern of vehicle images in the Hough space, and presents a feature to detect and classify vehicle images from samples with no vehicle contains. Instead of detecting straight line by seeking peaks in the Hough space, the Hough transform is employed in a novel way to extract features of images.

Space Charge in Exhaust of Motor Vehicles
Science, 1959Exhaust gases are electrically charged, usually positively but sometimes negatively. This charge does not depend on the electric potential of the vehicle. Whether the charge is positive or negative seems to depend on whether water droplets or carbon particles predominate in the exhaust.

Optimal Trajectories of Air and Space Vehicles*
Aircraft Engineering and Aerospace Technology, 2004The author developed a theory of optimal trajectories for air vehicles with variable wing area and conventional wings. He applied a new theory of singular optimal solutions and obtained the optimal flight in many cases. At first glance, the results may seem strange however, this is correct and this paper will show how this new theory may be used.
