Fuel economy

Wednesday, July 30th, 2008

Motorcycle fuel economy benefits from the relatively small mass of the vehicle. This, of course, relates to how the motorcycle is used. One person on a small motorcycle traveling a short distance is generally very economical. However a large motorcycle generally has bad aerodynamics compared with a typical car, poor aerodynamics of exposed passengers and engines designed for goals other than fuel economy can work to reduce these benefits. Riding style has a large effect on fuel economy.
Fuel economy varies greatly with engine displacement and riding style ranging from a low of 29 mpg (US) (12 km/l/35 mpg imp) reported by a Honda VTR1000F rider, to 107 mpg (US) (45 km/l/129 mpg imp) reported for the Verucci Nitro 50 cc Scooter. A specially designed Matzu Matsuzawa Honda XL125 achieved 470 mpg (US) (200 km/l/560 mpg imp) “on real highways - in real conditions.”

Advantages of NAT (Network Address Translator)

Sunday, July 6th, 2008

One of the important advantages of NAT is sharing of public IP address which helps in the conservation of IP address space. With the use of NAT the expansion process is made much simpler as private addresses are used within a local network. Since NAT allows a private network the controlling of the nodes inside the network is also easier. As only one public address is required to make contact with the outside networks the system will be more secure. This is because the unauthorized access to the nodes in the internal network will be restricted. The implementation of the NAT is transparent. It involves one or few routers.
