Evaluation of Unmanned Aerial Vehicles Introduction Unmanned aerial vehicles (UAVs) are aircrafts that do not require to be piloted by human beings; they do not have human pilots when they are in motion. Their flight is mostly guided by remote controls or by autonomously by computers. The typical launch and recovery of such vehicles is dependent on the capacity of an automatic function. The automatic function is dependent on some external operatives on the ground. Their main applications are military

the world run on? Can you imagine running your car on the most abundant thing in the universe? Hydrogen is the answer! Now with a little bit more refining it will be. Good morning fellow students today I will be talking about hydrogen powered vehicles. Firstly‚ some terms need definition.Hydrogen- a colourless‚ odourless‚ flammable gas which is the lightest and simplest of all known elements.Vehicle- A device or structure for transporting persons or things. Secondly‚ now to explain the ways

Throughout the years electric cars have always been behind gas powered vehicles. They have always been short on the side of performance and range. And most people want a vehicle that has lots of performance. America has opted for the more sporty and luxurious SUVs and trucks. These vehicles use a lot of gas to run‚ but are a way of American life. Electric cars did not start to become popular until the late 90’s‚ when the price of gas began to rise. In the beginning‚ electric cars were very slow.

launching its second Hybrid Electric Vehicle (HEV) to the market - a hybrid version of Honda’s top selling vehicle‚ the Civic. The company’s first HEV‚ the two-seater Honda Insight coupe‚ was introduced to the U.S. in 1999. It experienced modest sales of 3‚788 units in 2000 and 5‚000 units in 2001 and retailed at a base price of approximately $19‚100. However‚ demand outstripped supply and consumers were forced to wait between one to two months for their vehicles. Honda anticipates that sales of

Dynamic Memory Allocation Every Data or Instruction to be processed must be loaded into internal memory before its processing takes place. This process is called Memory allocation. These are of two types: Static and Dynamic Memory Allocation. First let’s talk about Static memory allocation. Here we reserve a certain amount of memory by default inside our program to use for variables‚ etc and this static memory is allocated during the compilation of the Program. Once we reserve this memory
