An inverse scattering problem in metallic waveguides filled with bianisotropic material

This paper presents an analysis with the aim of characterizing an arbitrary linear, bianisotropic material inside a metallic waveguide. The result is that if the number of propagating modes are the same inside and outside the material under test, it is possible to determine the propagation constants of the modes inside the material by using scattering data from two samples with different lengths.

Building-shielding loss modelling

An approach devised for shielding loss calculation and a model derived from it are outlined. The model handles a building of arbitrary dimensions occupied by wireless terminals with a given probability distribution and illuminated by a satellite. Two models for the probability distribution of the wireless terminals within a building are considered: uniform over the whole floor at a given height ab

A comparative analysis of three replicated experiments comparing inspection and unit testing

Code inspections and structural unit testing are two common defect detection methods in software development. This paper analyses three replications of an experiment aimed at comparing which method finds more defects. The first two experiments use the same experimental design and materials, including the programs to be inspected or tested, while the third experiment replaces the programs with code
