PURPOSE This study was performed to determine the optimal tile size for the fractal dimension of the mandibular trabecular bone using a tile counting method. MATERIALS AND METHODS Digital intraoral radiographic images were obtained at the mandibular angle, molar, premolar, and incisor regions of 29 human dry mandibles. After preprocessing, the parameters representing morphometric characterist...

Experiments have demonstrated that DNA molecules can compute like a machine to solve mathematical problems, which is significant because of their parallel computation ability. However, due to the nature of biochemical reactions, DNA computation suffers from errors, which are its main limitation. The abstract and kinetic Tile Assembly Models are now commonly used to simulate real DNA computing e...

We discuss the self-assembly system of triangular tiles instead of square tiles, in particular right triangular tiles and equilateral triangular tiles. We show that the triangular tile assembly system, either deterministic or non-deterministic, has the same power to the square tile assembly system in computation, which is Turing universal. By providing counter-examples, we show that the triangu...

Textile materials made from natural fibers have played an important role in the life of human beings from time immemorial and still are widely used in the modern textiles industry for their unique properties as high quality tex tile materials. Due to the variation in staple length, the natural fibers with short staple length can’t be used to spin yarns. Consequently, natural fibers such as wool...

Drawing on dynamic capabilities view, this work provides empirical evidence on the role of knowledge management practices on export intensity in SMEs in a mature and global, non-high-tech industry. A quantitative study with structural equation modeling was carried out on a sample of 157 Spanish and Italian manufacturing companies in the ceramic tile industry. Our results suggest the existence o...

A report of accidental poisoning of goats and cattle with the fertilizer, urea (46% Nitrogen) is made. All the fifteen goats IlJ1d five cattle involved in the intoxication eventually died. The clinical symptoms and pathological lesions were similar in both goats and cattle. There was a significant elevation of the blood urea nitrogen values in both cattle and goats; average for cattle being 39m...

Quality control is an important issue in the ceramic tile industry. Price of ceramic tiles also depends on purity of texture, accuracy of color, shape etc. Considering this criteria, an integrated defect detection and classification technique has been proposed which plays an important role in ceramic tiles industries to detect the defects and to control the quality of ceramic tiles.GLCM extract...
