Interference in interacting quantum dots with spin [PDF]

open access: yes, 2000
We study spectral and transport properties of interacting quantum dots with spin. Two particular model systems are investigated: Lateral multilevel and two parallel quantum dots.

Precise modelling of switching and conduction losses in cascaded h-bridge multilevel inverters [PDF]

open access: yes, 2014
Nowadays, voltage source multilevel inverters are being used extensively in industry due to its many advantages, compared to conventional two level inverters, such as higher output voltage at low switching frequency, low voltage stress(dv/dt), lower ...

Modular multilevel converter losses model for HVdc applications [PDF]

open access: yes, 2017
Multi-terminal high voltage dc (HVdc) grids can eventually became a feasible solution to transport energy to remote and/ or distant areas and its exploitation depend, among other things, on the performance of the converter terminals.

Multilevel Models with Stochastic Volatility for Repeated Cross-Sections: an Application to tribal Art Prices [PDF]

open access: yes, 2016
In this paper we introduce a multilevel specification with stochastic volatility for repeated cross-sectional data. Modelling the time dynamics in repeated cross sections requires a suitable adaptation of the multilevel framework where the individuals ...

On large-scale diagonalization techniques for the Anderson model of localization [PDF]

open access: yes, 2005
We propose efficient preconditioning algorithms for an eigenvalue problem arising in quantum physics, namely the computation of a few interior eigenvalues and their associated eigenvectors for large-scale sparse real and symmetric indefinite matrices of ...

Multilevel IRT Modeling in Practice with the Package mlirt [PDF]

open access: yes, 2007
Variance component models are generally accepted for the analysis of hierarchical structured data. A shortcoming is that outcome variables are still treated as measured without an error.

On proximity and hierarchy : exploring and modelling space using multilevel modelling and spatial econometrics [PDF]

open access: yes, 2009
Spatial econometrics and also multilevel modelling techniques are increasingly part of the regional scientists‟ toolbox. Both approaches are used to model spatial autocorrelation in a wide variety of applications. However, it is not always clear on which

Multilevel Coupled Model Transformations for Precise and Reusable Definition of Model Behaviour

open access: yes, 2019
The use of Domain-Specific Languages (DSLs) is a promising field for the development of tools tailored to specific problem spaces, effectively diminishing the complexity of hand-made software.

Tensor polarizability and dispersive quantum measurement of multilevel atoms [PDF]

open access: yes, 2005
Optimally extracting information from measurements performed on a physical system requires an accurate model of the measurement interaction. Continuously probing the collective spin of an Alkali atom cloud via its interaction with an off-resonant optical
