Distancing From Statistical Hazards: A Pursuit Drivers Herald
Abstract: When the passive drivers meet with accidents, it seems painful. When miscreant drivers cause accidents one feels annoyed, and curses the nasty driver and also the system. Statistics promises help in at least one way- i.e. keeping the safe distance between the two vehicles. Statistically speaking, frequency/ probability of happening of accidents is inversely proportional to the distance. The distance forms a bell shape in normal stopping situations on the …

Complementary Metal Oxide Semiconductor Readout Integrated Circuit for Imaging Applications
Abstract: In this paper presents a novel continuous-time simultaneous-readout scheme for active imaging systems based on orthogonal modulation of photo detector signals. The superimposed-continuous-time approach presented here differs from the conventional scheduled-discrete-time scheme in that the photo detector signals are summed in a common bus concurrently and then converted to voltage levels for digitization. We illustrate that our proposed architecture may be profitable. Predominantly, in solicitations, the bandwidth necessities for a …
