Complex variable theory provides a very powerful tool for the solution of many problems in elasticity. Such applications include solutions of the torsion problem and most importantly the plane problem discussed in Chapters 7 and 8 Chapter 7 Chapter 8 . The technique is also useful f...
Here we will consider integrals of complex valued scalar functions of a complex variable, so-called complex functions. The complex variable is denoted by z = x + iy, with x its real part and y its imaginary part. The function itself is generally complex valued, and can also be written as...
In ifort >= 2021.6 and ifx >= 2022.1 this example no longer compiles. In the most recent ifx (2024.1) the compiler gives the message: example.F90(13): error #9022: The argument to C_LOC must be a variable with the POINTER or TARGET attribute. [REAL] re_ptr = C_LOC(a...
Thus, if a single cell had vertices on edges 3 and 8, theVertexIDVolcould hold the index for only one of them. The easy solution is to triple the width of the vertex ID volume (making it 3NxNxNin size). When splatting, multiply the integer block-spacexcoordinate by 3...
A PMU measures the real-time voltage and line currents of its corresponding node, thus a PMU determines the state variable of not only the node it is placed on but also all its first-nearest neighbours. In this case, the observability problem can be mapped to a purely graph-theoretical ...

Iffis a real-valued function of a real variable and|f ′(x)| is bounded by a constant less than 1 on an interval, thenfis a contraction on that interval. Is the analogous statement true for a complex-valued function of a complex variable? Indeed it is. ...
‘filling’ the free-energy minima of the metastable states in a controlled way and thereby enabling the system to explore all states. To do so requires first choosing, on the basis of chemical or physical intuition, a low-dimensional collective variable (CV), namely, a function of the ...
