determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

Speed as a crucial phenomenon of modernism affects individual and collective life of human being and changes the traits of the places people live in. Increasing speed is the demand of the modern era, though on the other side in recent years there is a contrary incline towards slowing down different aspects of life. In view of this, the dualities in between social features of Speed up and slow d...

Let J? be any effective mapping from total functions on the integers to total functions. Composition and iterated composition are examples of such mappings. The "operator speed-up theorem in this paper establishes the existence of a computable function f such that for any program computing f(x) in Pj(x) steps for all x, there is another program computing f(x) in p 0(x) steps and F(p 0) < palmos...
