Integrated Photo-Electrochemical Solar Fuel Generators under Concentrated Irradiation- Part I: 2-D Non-Isothermal Multiphysics Modelling

Sophia Haussener, Saurabh Yuvraj Tembhurne

We investigate the direct conversion of solar energy and water into a storable fuel via integrated photo-electrochemical (IPEC) devices. Here we focus particularly on a device design which uses concentrated solar irradiation to reduce the use of rare and e ...

Dust grain coagulation modelling: From discrete to continuous

Paola Paruta

In molecular clouds, stars are formed from a mixture of gas, plasma and dust particles. The dynamics of this formation is still actively investigated and a study of dust coagulation can help to shed light on this process. Starting from a pre-existing discr ...

Error estimates for finite element approximations of nonlinear monotone elliptic problems with application to numerical homogenization

Assyr Abdulle, Martin Ernst Huber

We consider a finite element method (FEM) with arbitrary polynomial degree for nonlinear monotone elliptic problems. Using a linear elliptic projection, we first give a new short proof of the optimal convergence rate of the FEM in the L2 norm. We then deri ...

Wireless Channel Characterization in Burning Buildings Over 100-1000 MHz

Andrew Charles Mallory Austin

A 3-D implementation of the finite-difference time-domain (FDTD) method is used to model 100-1000-MHz radio wave propagation in a generalized office building. Fire within this building is modeled as a cold plasma medium. The presence of fire is found to de ...

Performance estimation for indoor wireless systems using FDTD method

Andrew Charles Mallory Austin

A three-dimensional implementation of the finite-difference time-domain method is used to estimate the down-link outage probability of a direct-sequence code division multiple access system operating in a multi-storey office building in the presence of co- ...

MATHICSE Technical Report : Nitsche’s method for parabolic Partial Differential Equations with mixed time varying boundary conditions

Alfio Quarteroni, Luca Dede', Anna Tagliabue

We investigate a finite element approximation of an initial boundary value problem associated with parabolic Partial Differential Equations endowed with mixed time varying boundary conditions, switching from essential to natural and viceversa. The switchin ...

Hamiltonian truncation study of the phi(4) theory in two dimensions

Lorenzo Vitale

We defend the Fock-space Hamiltonian truncation method, which allows us to calculate numerically the spectrum of strongly coupled quantum field theories, by putting them in a finite volume and imposing a UV cutoff. The accuracy of the method is improved vi ...

Quantum anomalies and logarithmic derivatives of feynman pseudomeasures

Tudor Ratiu

Connections between quantum anomalies and transformations of pseudomeasures of the type of Feynman pseudomeasures are studied. Mathematical objects related to the notion of the volume element in an infinite-dimensional space considered in the physics liter ...

Volume Integral Equation Formulation for Medical Applications

Juan Ramon Mosig, Michael Mattes, Ioannis Koufogiannis, Santiago Capdevila Cascante, Mina Bjelogrlic

In recent years, there is a considerable and growing interest in developing fast integral equation methods for solving Maxwell’s equations. Volume integral equations are a versatile technique to model inhomogeneous scattering objects. Numerical tests show ...

Finite element and finite volume-element simulation of pseudo-ECGs and cardiac alternans

Alfio Quarteroni, Ricardo Esteban Ruiz Baier

In this paper, we are interested in the spatio-temporal dynamics of the transmembrane potential in paced isotropic and anisotropic cardiac tissues. In particular, we observe a specific precursor of cardiac arrhythmias that is the presence of alternans in t ...
