An entirely analytical cosmological model
, 2008 The purpose of the present study is to show that in a particular cosmological model, with an affine equation of state, one can obtain, besides the background given by the scale factor, Hubble and deceleration parameters, a representation in terms of ...

Analytical solutions for the Rabi model
, 2012 The Rabi model that describes the fundamental interaction between a two-level system with a quantized harmonic oscillator is one of the simplest and most ubiquitous models in modern physics.

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 ...

Analytical model of overlapping Feshbach resonances
, 2013 Feshbach resonances in ultracold collisions often result from an interplay between many collision channels. Simple two-channel models can be introduced to capture the basic features, but cannot fully reproduce the situation when several resonances from ...

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 ...

Compact objects from gravitational collapse: an analytical toy model [PDF]
, 2015 We develop here a procedure to obtain regular static configurations as resulting from dynamical gravitational collapse of a massive matter cloud in general relativity. Under certain general physical assumptions for the collapsing cloud, we find the class

Journal of Sustainable Development of Energy, Water and Environment Systems, 2021 In this paper an analytical model for calculation of entropy production for Nusselt model of condensation of pure substance vapour is given. Model development starts from basic two-dimensional integral equation for entropy production and describes film ...

Analytical model of 1D Carbon-based Schottky-Barrier Transistors [PDF]
, 2009 Nanotransistors typically operate in far-from-equilibrium (FFE) conditions, that cannot be described neither by drift-diffusion, nor by purely ballistic models.
