Galilean Genesis is generically plagued with a strong coupling problem, but this can be avoided depending on the hierarchy between classical energy scale of genesis and scale. In paper, we investigate whether or not models without problem explain statistical properties observed CMB fluctuations based two unified frameworks Genesis. By focusing class in which propagation speeds scalar tensor per...

A coupling is a mechanism that transmits operative power between two shafts are revolving at different speeds. connects their ends and can slip or fail depending on the torque limit. It an essential component of any transmission system may survive for very long time if properly designed maintained. This study's current research, newly developed optimization algorithms used to minimize volume co...

Because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (TLSs). In this paper an exact solution for pitch vibration of a TLS interacting with ocean wave is presented. The legs of TLP are considered as elastic springs. The flow is assumed to be irrotational and single-valued velocity potentials are defined. The effec...

We consider the N-body problem in (1 + 1) dimensional lineal gravity. For 2 point masses (N = 2) we obtain an exact solution for the relativistic motion. In the equal mass case we obtain an explicit expression for their proper separation as a function of their mutual proper time. Our solution gives the exact Hamiltonian to infinite order in the gravitational coupling constant.
