Method of modeling roof age of a structure

A computer-implemented method for determining modeled roof age of a structure is provided. Such methods comprise identifying a target structure for which an estimated roof age is desired, receiving data related to the target structure in computer-readable form, and inputting the data related to the target structure into a generalized linear model to determine a Per-Property Modeled Roof Age of the target structure. The modeled roof age preferably accounts for (i) the height of the trees, (ii) the proximity of the trees to the target structure, and (iii) the weather conditions for the structure's geographic location. Such methods can be applied in practice by substituting a typically inaccurate reported roof age with a more realistic modeled roof age in making homeowners insurance decisions.

Temporal interferometric signal modeling with constant phase shift in white light interferometry

A method for determining the surface topography of an object with various surface properties in white light interferometry first generates a set of interferograms, produced by a phase shift driving mechanism supplied with known inputs, obtained from a single reflective surface at the location of the test piece. The sequence of interferograms from the test piece then is used to calibrate a sequence of inputs to the phase shift driving mechanism to compensate for non-linear characteristics of the phase shifting mechanism. The temporal interferometric signal or its transform at each pixel of a set of subsequently acquired interferograms from a test piece then is compared with signals or their transforms modeled with different properties of the measuring surface. The measured surface properties which generate a best match to the modeling surface properties are selected as the desired signal.
