aIn the present study a 4-stroke 5hp diesel engine was tested with Diesel oil plus cottonseed oil blends. The blends in different proportions (10 to 50 percent by volume) were tested at constant speed of 1500 rpm. The said engine is operated at different loads and characteristics like Brake power, Brake thermal efficiency, specific fuel consumption etc. Engine performance for blends resulted in...

In automatic highway systems, a faster response and a robust braking system are crucial part of the overall automatic control of the vehicle. This paper describes electromagnetic brakes as a supplementary system for regular friction brakes. This system provides better response time for emergency situations, and in general keeps the friction brake working longer and safer. A modified mathematica...

Ouabain, at all concentrations higher than 2 x 10(-7) mol l-1, stimulates the rate at which the Malpighian tubules of the insect, Rhodnius, transport sodium ions and fluid into the lumen. An effect on paracellular movement of sodium ions is unlikely because ouabain makes the electrical potential of the lumen more positive, which would slow diffusion of sodium into the lumen. Radioactive ouabain...

Abstract Air brake systems are critical equipment for railway trains, which affects the running safety of trains significantly. To study air braking characteristics long freight , an approach simulating based on fluid dynamics theory was proposed. The structures and working mechanisms locomotive wagon brakes introduced, mathematical models pipes, valves, reservoirs or chambers, cylinders, etc.,...

This investigation was completed as part of the ITS-IDEA Program which is one of three IDEA programs managed by the Transportation Research Board (TRB) to foster innovations in surface transportation. It focuses on products and result for the development and deployment of intelligent transportation systems (ITS), in support of the U.S. Department of Transportation's national ITS program plan. T...

The overall potential for recoverable tidal energy depends partly on the turbine technologies used. One of problematic points is minimum flow velocity required to set rotor into motion. novelty paper setup an innovative method model fluid–structure interactions turbines. first part this work aimed at validating numerical classical cases rotation (forced rotation), in particular, with help a mes...
