that the phase velocity of an electromagnetic wave propagating between parallel metal sheets depends on the distance between them if the electric field vector is parallel to the sheets. In such a case the phase velocity is greater than the speed of light‚ and the refractive index is less than unity. Zoning the surfaces of a lens antenna reduces its weight and dimensions. The shape and height in profile of the individual zones are chosen such that the electromagnetic waves refracted by adjacent zones

Chandhar Abstract : Ubiquitous smartphones are increasingly becoming the dominant platform for collaborative sensing.Smartphones‚ with their ever richer set of sensors‚ are being used to enable collaborative driver-assistance services like traffic advisory and road condition monitoring. To enable such services‚ the smartphones’ GPS‚ accelerometer and gyro sensors have been widely used. On the contrary‚ smartphone cameras‚ despite being very powerful sensors‚ have largely been neglected. In

AND ANSWERS ABOUT TRAFFIC JAMS January 2012 LISTENING TO THE TRAFFIC JAM INFORMATION IS NOT THE MOST PLEASURABLE MOMENT OF THE DAY FOR MANY. ISN’T IT TIME TO SOLVE ALL THOSE TRAFFIC JAMS? THAT’S PROBABLY NOT GOING TO HAPPEN. BUT WE CAN LOOK AT THINGS IN A DIFFERENT WAY. HOW CAN WE BOOST THE ACCESSIBILITY OF LOCATIONS AND THE RELIABILITY OF OUR TRAVEL INFORMATION? WHAT ALTERNATIVES CAN WE DEPLOY? OR‚ HOW CAN WE FACILITATE MOBILITY? TEN QUESTIONS AND ANSWERS ABOUT TNO AND TRAFFIC JAMS. JRV090112-02

G1 Rules On a roadway where traffic is moving in both directions‚ in what lane must a driver be before making a left turn? Lane to the right of the center line of the roadway How many meters in both directions must the driver be able to see in order to make a U-turn? 150 m Approaching a yield sign: Slow down‚ stop if necessary‚ proceed when the way is clear High Occupancy Vehicle (HOV) reserved for at least two people/occupants Police can immediately suspend driver’s license up to three days

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

We can see through the results that there isn’t a normal proportional relationship between the wavelength of the light and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least

Is it in the best interest of South Africa to shift freight traffic from road transport to rail? I believe that it is in the best interest of South Africa to shift freight traffic from road transport to rail for various convincing and some obvious reasons. The most convincing reasons being a result of reduced road maintenance costs and congestion‚ greater safety on the roads‚ overall transport and logistics cost reductions‚ reduced overall impact of rising fuel prices and the fact that South Africa

Air traffic control (ATC) is a service provided by controllers who direct aircraft on the ground and in the air. The main function of ATC systems worldwide is to separate aircraft to avoid collisions‚ to organize and expedite the flow of traffic‚ and to provide information and other support for pilots when able. In some countries‚ ATC may also play a security or defense role (as in the United States)‚ or actually be run entirely by the military (as in Brazil). Air traffic control was first introduced

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in
