Analytical Heavy Quark Expansion in the 't Hooft Model [PDF]
, 2000 We present a number of exact relations for the heavy quark limit and develop an analytical 1/m_Q expansion for heavy mesons in the 't Hooft model. Among the new results are relation 3\mu_\pi^2=\bar\Lambda^2 - m_{sp}^2+\beta^2, 1/m_Q corrections to the ...

COBE vs Cosmic Strings: An Analytical Model
, 1992 We construct a simple analytical model to study the effects of cosmic strings on the microwave background radiation. Our model is based on counting random multiple impulses inflicted on photon trajectories by the string network between the time of ...

An analytical model for Loc/ID mappings caches [PDF]
, 2016 Concerns regarding the scalability of the interdomain routing have encouraged researchers to start elaborating a more robust Internet architecture. While consensus on the exact form of the solution is yet to be found, the need for a semantic decoupling ...

An analytical model for bore-driven run-up [PDF]
, 2008 We use a hodograph transformation and a boundary integral method to derive a new analytical solution to the shallow-water equations describing bore-generated run-up on a plane beach.

Harmonic generation by atoms in circularly polarized two-color laser fields with coplanar polarizations and commensurate frequencies [PDF]
, 2002 The generation of harmonics by atoms or ions in a two-color, coplanar field configuration with commensurate frequencies is investigated through both, an analytical calculation based on the Lewenstein model and the numerical ab initio solution of the time-

Analyticity in Hubbard Models [PDF]
Journal of Statistical Physics, 1999 The Hubbard model describes a lattice system of quantum particles with local (on-site) interactions. Its free energy is analytic when t is small, or t^2/U is small; here, is the inverse temperature, U the on-site repulsion and t the hopping coefficient. For more general models with Hamiltonian H = V + T where V involves local terms only, the free

SensorsThe eddy current testing (ECT) technique enables efficient and non-destructive conductivity measurement. However, conventional ECT is significantly influenced by the thickness of the material, often resulting in the arbitrary selection of excitation ...

SVC Dynamic Analytical Model [PDF]
IEEE Power Engineering Review, 2002 This paper presents a linear state-space model of a static VAr compensator. The model consists of three individual subsystem models: an AC system, a SVC model and a controller model, linked together through d-q transformation. The issue of non-linear susceptance-voltage term and coupling with a static frame of reference is resolved using an artificial ...
