problems motion

problems motion : Motion perception is the process of inferring the speed and direction of objects that move in a visual scene given some visual input. See also: Mind & Brain Perception Psychology Computers & Math Computer Graphics Computer Science Computer Programming While this process appears straighforward to most observers, it has proven to be a hard problem from a computational perspective, and extraordinarily difficult to explain in terms of neural processing. Motion perception has connections to both neurology (i.e. visual perception) and computer science..

Students should first draw a diagram to represent the relationship between the distances involved in the problem, then set up a chart based on the formula rate times time = distance. The chart is then used to set up the equation....

Question : Can anybody help me cite projectile-motion based situations during World War 2 where you think these computers were used?

Answer : WW II was really the first war where ships fought each other beyond visual range and even at night. Allied battleships used RADAR to locate enemy ships. Crude computers were used to solve the ballistic equations and direct the shells on target...   More from Yahoo Answers

Question : I have tried to replace bulbs in three different motion sensor fixtures with CFLs and had problems with all. The ones in my garage will turn on, but the lights will start to flicker within a couple minutes. The fixtures on the outside of my garage, will turn on when the motion sensor is activated, but do not shut off after 10 minutes as they should. All of these fixtures work fine with incandescent bulbs in them. All of the bulbs/fixtures I have replaced inside work fine with the CFLs, and I hav..

Answer : most motion sensors are constantly drawing a small portion of the power requirement from the circuit to keep operaational. CFL or all fluorescent bulbs are made to use the full 120volts supplied by regulated AC current which is stepped up to a higher voltage in order to fire the gasses inside the fluorescent bulb. IF the power gets below 120v, like, say 108, or 105 volts, a regular incandescent bulb will actually last LONGER, while the drop in voltage will not allow the fluorescent to fire completely. That's why you get the flicker affect, and probably will find that they won't last very long...   More from Yahoo Answers
