We describe mechanisms for automated evolution of ontologies to adapt to new circumstances and to make them better suited to the given task. If a conflict is detected between the original theory and new experimental evidence, a repair is required to resolve the inconsistency and to recover from failure. The rules for conflict diagnosis and transformation of the ontologies are composed together ...

This paper presents a fast and efficient way for color reindexing that tends to maximize the compression performance of a palette-based compression system. The proposed scheme relates the index difference of neighboring pixels to the potential cost of bits. It optimizes the assignment of index values to colors in a one-step look-ahead greedy fashion. Experimental results suggest that the propos...

We propose and demonstrate weak-microcavity organic light-emitting diode (OLED) displays with improved light-extraction and viewing-angle characteristics. A single pair of low- and high-index layers is inserted between indium tin oxide (ITO) and a glass substrate. The electroluminescent (EL) efficiencies of discrete red, green, and blue weak-microcavity OLEDs are enhanced by 56%, 107%, and 26%,...

the increasing tendency for health oriented products caused considerable research has studied on increase and maintaining quality of different products. sponge cake is one of the cereal products which itsmain problems arereterogradation and lack of soluble dietary fibers which has many health benefits. in this research, therefore, the effects of adding oat β-d-glucan on the physical properties ...

The paper presents the color image segmentation based on rough-set approach has been proposed. The color image segmentation is one of the most challenging tasks particularly in the area of image analysis, computer vision, and pattern recognition. In this paper, the proposed algorithm based on roughness index to calculate the peaks and valleys values. Based on peak and valley values to achieve b...

Combined surface, structural and opto-electrical investigations are drawn from the chemically fashioned ZnO nanotubes and its heterostructure with p-GaN film. A strong correlation has been found between the formation of radiative surface defect states in the nanotubes and the pure cool white light possessing averaged eight color rendering index value of 96 with appropriate color temperature. Hi...

Cum, h/I. J., AND T, A. WALDMANN. Effect uf temperature on er~~hropaiesis and Ted cell survival in the frog. Am. J. Physiol. 203 (3) : 401-403. I g62.-The effect of environmental temperature on erythropoiesis and erythrocyte life span was studied in frogs maintained at 4 C or 24-26 C. The red cell incorporation of radioiron was used as an index of the rate of erythropoiesis and diisopropylfluor...

AN ASSESSMENT OF PRINT GRAININESS FROM COLOR NEGATIVE FILMS Print Grain Index refers to a method of defining graininess in a photographic color print, typically made from a color negative. The Print Grain Index method replaces rms (root-mean-square) granularity and has a different scale which cannot be compared with rms granularity. This method is designed to be more meaningful to viewers who a...

The best performance of the phosphor Li(2)SrSiO(4): Eu(2+), Ce(3+) in terms of luminescence efficiency (LE), color rendering index (CRI) and color temperature (Tc) for light-emitting diode application was optimized with combinatorial approach. The combinatorial libraries were synthesized with solution-based method and the scale-up samples were synthesized with conventional solid-reaction method...
