Large database schemata can be drastically simplified if techniques of modular and structural modeling are used. Applications and thus schemata have an inner meta-structure. The explicit treatment of the inner structuring may be used during development of large database schemata and may ease the development to a large extent. It is surprising that dimensions and internal separations have not be...

We show that recent results on randomized dimension reduction schemes that exploit structural properties of data can be applied in the context of persistent homology. In the spirit of compressed sensing, the dimension reduction is determined by the Gaussian width of a structure associated to the data set, rather than its size, and such a reduction can be computed efficiently. We further relate ...

In this study, phthalimide derived polymer-TiO2 nanocomposites were prepared by direct mixing method and their mechanical properties compared. The high content filler polymer with sufficient interface bonding the matrix have been to maximize of filler. method, obtained free radical polymerization monomer was mixed TiO2 in weight percentages. pulse-echo used characterize elastic constants throug...

As one of Full Field Optical Measurement (FFOM) technologies, Smart 3-D Laser Scanner measurement technique enables to monitor the shape and dimension measured-objects in non-contact, remotely and globally. By taking its capability in capturing 3-D spatial information, 3-D Laser Scanner has been utilized effectively in numerous field application, such as, landscaping simulation during structura...

Cracks emerge due to various forces or stresses. After discerning the cracks preferably by non-destructive techniques, there is a need to find the reason for their appearance. With very exact analysis of the shape, form and dimension of the cracks and their location on the structural elements, we can deduce the reason for their formation.  This makes, proposing a suitable solution for preventin...
