Numerical Experiments in String Cosmology [PDF]
Nuclear Physics B, 1995 We investigate some classical aspects of fundamental strings via numerical experiments. In particular, we study the thermodynamics of a string network within a toroidal universe, as a function of string energy density and space dimensionality.

Resolving Gas Bubbles Ascending in Liquid Metal from Low-SNR Neutron Radiography Images
Applied Sciences, 2021 We demonstrate a new image processing methodology for resolving gas bubbles travelling through liquid metal from dynamic neutron radiography images with an intrinsically low signal-to-noise ratio.

An Invariant-Preserving Scheme for the Viscous Burgers-Poisson System
Computation, 2021 We formulate and analyze a new finite difference scheme for a shallow water model in the form of viscous Burgers-Poisson system with periodic boundary conditions. The proposed scheme belongs to a family of three-level linearized finite difference methods.

Experiments in orbit determination using numerical methods [PDF]
, 1985 The dynamics of the observed object is written as a system of integral equations. This system is solved numerically by representing the components of the force function as linear combinations of B-splines and by applying the multigrid technique.

Magnetic helicity in stellar dynamos: new numerical experiments [PDF]
, 2001 The theory of large scale dynamos is reviewed with particular emphasis on the magnetic helicity constraint in the presence of closed and open boundaries. In the presence of closed or periodic boundaries, helical dynamos respond to the helicity constraint
