A Simple Analytical Model for Gaps in Protoplanetary Disks

open access: yes, 2015
An analytical model is presented for calculating the surface density as a function of radius $\Sigma(r)$ in protoplanetary disks in which a planet has opened a gap. This model is also applicable to circumbinary disks with extreme binary mass ratios.

Optimum Analytical Model for the Drift Region of Silicon Carbide Uni-polar Power Device

open access: yesKongzhi Yu Xinxi Jishu, 2015
Currently,doping concentration uniformity of epi-wafers is poor and thickness of epi-layer is sensitive to cost and defect density. An optimum analytical model for the drift region of uni-polar silicon carbide (SiC) power device and an optimum control ...

Analytical Model for the Structural Behavior of Pipelines During Lowering-In

open access: yesApplied Sciences, 2019
Since pipelines experience the largest deformation during lowering-in, structural analysis for this construction sequence should be performed to ensure structural safety.

Modeling of Zinc Dynamics in the Synaptic Cleft: Implications for Cadherin Mediated Adhesion and Synaptic Plasticity

open access: yesFrontiers in Molecular Neuroscience, 2018
While the numerous influences of synaptically released zinc on synaptic efficiency during long-term potentiation have been discussed by many authors already, we focused on the possible effect of zinc on cadherins and therefore its contribution to ...

Rigorous Analytical Model for Metasurface Microscopic Design with Interlayer Coupling

open access: yes, 2019
We present a semianalytical method for designing meta-atoms in multilayered metasurfaces (MSs), relying on a rigorous model developed for multielement metagratings.

Thermal Modeling of Temperature Distribution in Metal Additive Manufacturing Considering Effects of Build Layers, Latent Heat, and Temperature-Sensitivity of Material Properties

open access: yesJournal of Manufacturing and Materials Processing, 2018
A physics-based analytical model is proposed in order to predict the temperature profile during metal additive manufacturing (AM) processes, by considering the effects of temperature history in each layer, temperature-sensitivity of material properties ...

An analytical model for elasto-plastic buckling of columns [PDF]

open access: yes, 2013
The theory of buckling strength of compression members in the plastic range has been extensively studied, and numerical methods already exist which deal with such behaviour.

Analytical ground state for the three-band Hubbard model

open access: yes, 1999
For the calculation of charge excitations as those observed in, e.g., photo-emission spectroscopy or in electron-energy loss spectroscopy, a correct description of ground-state charge properties is essential.

Analytical results for the Sznajd model of opinion formation

open access: yes, 2003
The Sznajd model, which describes opinion formation and social influence, is treated analytically on a complete graph. We prove the existence of the phase transition in the original formulation of the model, while for the Ochrombel modification we find ...

An analytical model of a clamped sandwich beam under low-impulse mass impact

open access: yesLatin American Journal of Solids and Structures
An analytical model is developed to examine a low impulsive projectile impact on a fully clamped sandwich beams by considering the coupled responses of the core and the face sheets.
