structural dynamic parameters: natural period, shape modes and damping ratio of vibration, play a decisive role on the seismic behavior of those structures. there are several methods for determining of the structural dynamic parameters, such as: free vibration, ambient vibration and force vibration tests. in this research the structural response of a three-story building (the natural frequencie...

This paper proposes a solution to the problem of re-phasing circular or low eccentricity orbiting, short-distance spacecraft, by integrating existing analytical guidance solutions based on input-shaping and analytical control techniques for differential drag based on Lyapunov theory. The combined guidance and control approach is validated via numerical simulations in a full nonlinear environmen...

The paper presents a new analytical method for blocking probability determination in the WCDMA interface of the UMTS network with priorities. In our considerations we use a new model of the full-availability group servicing PCT1 and PCT2 multi-rate traffic with priorities. The proposed scheme is applicable for cost-effective WCDMA resource management in 3G mobile networks and can be easily appl...

Having validated analysis methods for medicinal ingredients is attractive for pharmaceutical companies. When a new molecule is introduced to the market, there is not any pharmacopeial analysis method for that. After publishing official methods, correlation between validated in-house methods and the official one could stablish the value of the in-house method. Sitagliptin phosphate is a new anti...

We present a useful analytical method for designing grating-compensated dispersion-managed (DM) soliton systems for any desired input pulse widths and energies. The pulse-width and chirp evolution equations derived from the variational method are solved exactly to obtain the explicit analytical expressions for the length of the dispersion map and the grating dispersion. We also extend our analy...

Full-dimensional ab initio potential energy surface is constructed for the H(7)(+) cluster. The surface is a fit to roughly 160,000 interaction energies obtained with second-order MöllerPlesset perturbation theory and the cc-pVQZ basis set, using the invariant polynomial method [B. J. Braams and J. M. Bowman, Int. Rev. Phys. Chem. 28, 577 (2009)]. We employ permutationally invariant basis funct...

I present a simplified analytical model that simulates the evolution of the binary population in a dynamically evolving globular cluster. A number of simulations have been run spanning a wide range in initial cluster and environmental conditions by taking into account the main mechanisms of formation and destruction of binary systems. Following this approach, I investigate the evolution of the ...

Motivated by the resource management problem in nonlinear multi-sensor tracking networks, the paper derives online, distributed estimation algorithms for computing the posterior Cramér-Rao lower bound (PCRLB) for full-order and reduced-order distributed Bayesian estimators without requiring a fusion centre and with nodal communications limited to local neighborhoods. For both cases, Riccati-typ...

We present the first completely analytical computationof the full differentialγ-γ pair production rate fromcompact radiation fields, exact to 2nd order QED, and use this result to investigate the validity of previously known approximations.
