Tension-Leg Platform (TLP) is a vertically moored floating structure. The platform is permanently mooredby tendons. Surge equation of motion of TLP is highly nonlinear because of large displacement and it should be solved with perturbation parameter in time domain. This paper compare the dynamic motion responses of a TLP in regular sea waves obtained by applying three method in time domain usin...

Seery and Lidsey have calculated the three-point correlator of the light scalar fields, a few Hubble times after horizon exit during inflation. Lyth and Rodriguez have calculated the contribution of this correlator to the three-point correlator of the primordial curvature perturbation. We calculate an upper bound on that contribution, showing that it is too small ever to be observable. Introduc...

this study aimed to evaluate the effects of auditory-verbal rehabilitation on voice parameters after implantation with cochlear implants 2 and 5 months after rehabilitation and compare them with normal voice children (under 12 years of age). a perceptive and electroacoustic evaluation of voice was carried out through a digital analysis after implantation and rehabilitation. the study was perfor...

Ensemble–variational data assimilation algorithms that can incorporate the time dimension (fourdimensional or 4D) and combine static and ensemble-derived background error covariances (hybrid) are formulated in general forms based on the extended control variable and the observation-space-perturbation approaches. The properties and relationships of these algorithms and their approximated formula...

Motor adaptation to an external perturbation relies on several mechanisms such as model-based, model-free, strategic, or repetition-dependent learning. Depending on the experimental conditions, each of these mechanisms has more or less weight in the final adaptation state. Here we focused on the conditions that lead to the formation of a model-free motor memory (Huang VS, Haith AM, Mazzoni P, K...

We describe a new kind of resonance occuring in relativistic three-body hierarchical systems: the precession resonance, when timescale binary equals period distant perturber. find that, contrary to what most previous studies assume, it can lead an exponential increase eccentricity even dominates quadrupolar perturbation. The may happen observation band LISA or change distribution triples. discu...

An analysis has been conceded to study the effects of Soret and thermal radiation effects on the magnetohydrodynamic convective flow of a viscous, incompressible, electrically conducting fluid with heat and mass transfer over a plate with time-dependent suction velocity in a slip flow regime in the presence of first-order chemical reaction. The slip conditions at the boundaries for the governin...

Perturbation series for the electron propagator in the Schwinger Model is summed up in a direct way by adding contributions coming from individual Feynman diagrams. The calculation shows the complete agreement between nonperturbative and perturbative approaches. 11.10.-z;11.15.Bt;12.90.+b Typeset using REVTEX Electronic mail: [email protected] 1 A long-standing question in quantum field theory ...

The order dependent mapping method, its convergence has recently been proven for the energy eigenvalue of the anharmonic oscillator, is applied to re-sum the standard perturbation series for Stark effect of the hydrogen atom. We perform a numerical experiment up to the fiftieth order of the perturbation expansion. A simple mapping suggested by the analytic structure and the strong field behavio...
