Background. The theory of solving inverse problems of mathematical physics is one of the most actively developing branches of modern mathematics. The interest of researchers in such problems is primarily due to the large number of their applications ...

Status of the current parabolic dish technology [PDF]
Vu-graphs are presented that show that point focus distributed receiver distributed generation systems are cost competitive with current utilities. System cost caveats and typical power module costs are described.

Unravelling the Spatiotemporal Exciton Dynamics in Electrically Pumped Organic Laser Diodes
High‐speed OLED measurements combined with advanced simulations reveal how singlet, triplet, and polaron dynamics drive key loss channels that hinder organic semiconductor lasing, while presenting strategies to overcome them. Abstract Organic materials offer wide‐band emission covering regions of the spectrum unachievable by conventional semiconductors.

Parabolic transmission problems across irregular layers
We study second order transmission problems across either a fractal surface or across the corresponding pre-fractal surface. Existence uniqueness and regularity results for the strict solution in both cases are proved.The asymptotic behaviour of the ...

Time integration and the Trefftz Method Part I - First-order and parabolic problems
The finite element method is applied in the time domain to establish formulations for the integration of first-order and parabolic (transient) problems. The modal decomposition concept is applied using two distinct approaches.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems
ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.

Boundary value problems for essentially-loaded parabolic equation
In this paper we investigate the first boundary value problem for essentially loaded equation of heat conduction, i.e. when laden terms are derivatives for any finite order.
