Using Pole–Pole Measurements to Calculate Arbitrary 4‐Point Configurations—An Approach to Make Electrical Resistivity Tomography More Flexible and Time‐Efficient

Archaeological Prospection, EarlyView.
ABSTRACT Electrical resistivity tomography (ERT) is nowadays widely used in archaeological prospection. This study deals with an approach to make ERT more time‐efficient and flexible. It is based on calculating arbitrary 4‐point configurations by superposition of multiple pole–pole measurements.

Photophysical and Chiroptical Properties of Pyrazino‐Phenanthroline‐Helicene Derivative and its Rhenium(I) Complex

Chemistry – An Asian Journal, EarlyView.
The preparation and characterization of the first helical pyrazino‐phenanthroline ligand, namely [4]helicene‐pyrazino[2,3‐f][1,10]phenanthroline (H4PP) and its corresponding Re(CO)3Cl complex (Re‐H4PP) are described. The photophysics and chiroptics (circular dichroism and circularly polarized luminescence) of these new chiral systems are thoroughly ...

Coefficient Identification in Elliptic Partial Differential Equation [PDF]

Large-Scale Scientific Computing, 2006
We consider the inverse problem for identification of the coefficient in an elliptic partial differential equation inside of the unit square $\mathcal{D}$, when over-posed boundary data are available. Following the main idea of the Method of Variational Imbedding (MVI), we “imbed” the inverse problem into a fourth-order elliptic boundary value problem ...

Elliptic partial differential equation and optimal control

Numerical Methods for Partial Differential Equations, 1992
AbstractThe theory of optimal control and the semianalytical method of elliptic partial differential equation (PDE) in a prismatic domain are mutually simulated issues. The simulation of discrete‐time linear quadratic (LQ) control with the substructural chain problem in static structural analysis is given first.

Elliptic Partial Differential Equations of Second Order

1997
We study in this chapter a class of partial differential equations that generalize and are to a large extent represented by Laplace’s equation. These are the elliptic partial differential equations of second order. A linear partial differential operator L defined by $$ Lu{\text{: = }}{a_{ij}}\left( x \right){D_{ij}}u + {b_i}\left( x \right){D_i}u +
