One of expensive stages the software lifecycle is its maintenance. Software maintenance will be much simpler if structural models are available. module clustering thought to a practical reverse engineering method for building from source code. The most crucial goals in minimize connections between created clusters, maximize internal within and quality. It that finding best model an NP-complete ...

Desert roses are gypsum crystals that consist of intersecting disks. We determine their geometrical structure using computer assisted tomography. By mapping the geometrical structure onto a graph, the topology of the desert rose is analyzed and compared to a model based on diffusion limited aggregation. By comparing the topology, we find that the model gets a number of the features of the real ...

The software engineering community is working to develop reliable metrics improve quality. It estimated that understanding the source code accounts for 60% of maintenance effort. Cognitive informatics important in quantifying degree difficulty or efforts made by developers understand code. Several empirical studies were conducted 2003 assign cognitive weights each possible basic control structu...

in this study, some habitat characteristics of iranian rose (hulthemia persica) were studied in gonbad watershed in hamedan providence, iran. soil samples were taken by a systematic randomized method at elevation 2000-2400 m above sea level. samples were taken from 0-30 cm depth. in the laboratory, n, p, k% and organic matter (oc%), soil acidity (ph), conductivity (ec) and soil texture were det...

a simple and sensitive extraction-fluorimetric method for the determination of copper is reported. the 1,7-diaza-15-crown-5-copper-rose bengal (da15c5-cu-rb) ternary complex is quantitatively extracted into chloroform, diluted with ammoniacal acetone and its fluorescence intensity is measured at 570 nm with excitation at 540 nm. a linear calibration graph was obtained over the copper concentrat...

An increase in intracellular Ca2+ concentration ([Ca2+]) and morphological were simultaneously observed by epifluorescence and differential interference contrast (DIC) microscopy during fertilization of the sand dollar, Clypeaster japonicus. [Ca2+], which was detected by a Ca2+ indicator, Fluo-3, initially increased just beneath the sperm-attached site on the egg surface 8.6 sec after attachmen...
