In DCF using fragmentation increased the delay as the collisions increased while fragmentation decreased the delay when used with PCF. Using fragmentation in DCF did not affect the load much and it remains nearly the same. However‚ using PCF resulted in load drop and when we used fragmentation with PCF the load decreased even more. As expected‚ the throughput of WLAN uses PCF was higher than WLAN with only DCF enabled because collisions decrease by using free contention free period. However

features that protect the drivers and passengers. First‚ and the most common safety feature‚ seat belt. Seatbelt or safety belt is a safety harness‚ which is designed to secure the occupant of a vehicle against harmful movement (that may result from a collision or a sudden stop). As part of a passive safety system‚ seat belts are planned to reduce injuries by stopping the wearer from hitting hard elements of the vehicle‚ or other passengers (so-called second impact). Seatbelts are placed in the correct

The meaning of inertia Inertia is the property of an object which resists a change in its motion. If it is at rest it tends to remain at rest ‚ if it is moving it tends to continue moving. Or Inertia is the reluctance of an object to move once it is at rest or the reluctance of an object to stop once it is in uniform velocity. Explanation of inertia by Newton’s First Law of Motion Newton’s First Law of Motion states that “an object will remain at rest or continue with a constant

stopping distances by up to 70 ft (21 m) at 125 mph (201 km/h) * The Volvo system Collision Warning with Auto Brake ’CWAB’ uses radar to detect when a collision is likely and will pre-charge the brakes so that when the driver uses the brakes‚ however lightly‚ full braking is applied. The system will also flash a light and make a warning sound‚ if the driver does not respond to the warning at the point where a collision cannot be avoided

5.05 – Rate and Collision Theory Materials: -Water -Alka-Seltzer tablets -Thermometer -2 Small glass cups -Phone (to use as a timer) -2 big class cups Procedure: 1. Using the glass‚ fill it with water that is 25 degrees Celsius‚ use the thermometer to make sure the temperature is correct. 2. Have my phone ready to time how long it takes for the tablet of alka-seltzer to dissolve in the water. 3. Then‚ getting another cup‚ we have room temperature water. Then‚ we drop another alka-seltzer

glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful collisions increases and results in a higher respiration rate. The reaction then levels out and begins to reduce‚ this may happen because there are too many yeast cells and they are actually preventing successful collisions and‚ in a way‚ ‘suffocating’ each other‚ or it

Will the LHC Destroy the World? The LHC will allow scientists to observe particle collisions at an energy level far higher than any previous experiment. Some people worry that such powerful reactions could cause serious trouble for the Earth. In fact‚ a few people are so concerned that they filed a lawsuit against CERN in an attempt to delay the LHC’s activation. In March 2008‚ former nuclear safety officer Walter Wagner and Luis Sancho spearheaded a lawsuit filed in Hawaii’s U.S. District Court

shipping. It was so busy that the harbour traffic control couldn’t keep up with the sheer volume of ships passing through daily. Collisions were frequent in the harbour. The ships usually followed "the rules of the road"‚ which meant that ships had to pass each other on the right and signal their intentions and respect those of others. The two ships involved in the collision‚ the Monte-Blanc and the Imo did not adhere to any of the harbour rules. The devastating explosion could have been averted if
