Let us consider the one-dimensional Schrödinger equation with the scattering potential V(x)=2δ(x) and corresponding reflection coefficient b(k)=−i/(k + i). The potential satisfies a theorem of Deift and Trubowitz which states that non-negative measurable potentials V(x) satisfying a ...
Advanced product quality: Product quality planning process that supports development of a planning (APQP) product or service that will satisfy customer requirements; APQP serves as a guide in the development process and also a standard way to share results between organizations and their customers; AP...
One of them is string concatenation — essentially, appending one string onto another. In Java code it looks like this: String s = "Now is the time"; s += " for all good men"; s += " to come to the aid"; s += " of their country."; System.out.println(s); String ...

The transport of the conservative tracer in a porous medium involves processes such as advection, diffusion and dispersion. In addition, the reactive tracer is also subject to equilibrium or nonequilibrium sorption processes. Generally, one-dimensional (1D) transport of the tracer subject to transport...

When dealing with precision in tolerancing of assembly systems, the modelling complexity of the mechanism increases. At first, one can distinguish the 1D tolerancing approach that only concerns variations of dimension. Then, several models are defined to
Fourier Transform Infrared Spectrometer (FTIR) has been reported to be more widely used, but it has problems with low apparent resolution and overlapping of the characteristic peaks [11]. Three-dimensional correlation spectroscopy (3DCOS) can transform complex spectral data into a more intuitive ...
The two-dimensional ordered array of atoms on a crystalline surface give atomic scale surface height fluctuations, which exhibits the exciting beauty of the microscopic world. Rough surfaces make up one very important part in the world. In practice, one may want to use the property of a rough...
Two-dimensional (2D) materials combine many fascinating properties that make them more interesting than their three-dimensional counterparts for a variety of applications. For example, 2D materials exhibit stronger electron-phonon and electron-hole inter
