We present a new approach to a componentware development methodology based on a system of process patterns. We argue that organizing the development process by means of a pattern system results in higher flexibility compared to traditional ways of defining development processes. This is especially important in the context of componentware. Finally, we propose a pattern catalog with a selection ...

In this paper we evaluate several extensions of Local Binary Patterns to color images. In particular, we investigate their robustness with respect to changes in the illuminant color temperature. To do so, we recovered the spectral reflectances of 1360 texture images from the Outex 13 data set. Then, we rendered the images as if they were taken under 33 different illuminants. For each combinatio...

The effect of dehydroepiandrosterone (DHEA) on the activity and isoenzyme patterns of liver glucose 6- phosphate dehydrogenase (G6PD) was investigated in rats during different stages of growth. G6PD activity of mature rats was less than those of the immature (43%) and newborn (35%) animals. DHEA at 10 M) inhibited G6PD activity of the mature , immature and newborn rats by 79%, 39% , and 88%...

To test for “randomness” in spatial point patterns, we propose two test statistics that are obtained by “reducing” two-dimensional point patterns to the one-dimensional one. Also the exact and asymptotic distribution of these statistics are drawn.

one of the great events in the history of iran is the emergence and spread of islam within the early hegira centuries.  the result of the interaction between islam and iran was transformations in many cultural dimensions and indices. this research states the problem of the islamization of iranian lifestyle andthe culture of purity and impurity, in particular.in this article,interpretive-analyti...

in this research, effect of north atlantic oscillation and sea surface temperature (sst) of atlantic ocean on precipitation and temperature of lorestan province and its effect on occurrence of drought and wet in this province were investigated. so, data of teleconnection indices used as an index for determination of fluctuations of pressure and sea surface temperature in atlantic ocean, amount ...

Design patterns may introduce a new perspective on the traditional subject of data structures. They introduce more flexibility and reusability in data structures implementation and use. This analysis shows that design patterns could bring important advantages in basic fields of Computer Science, too. Beside the advantages brought for data structures, presenting them in this perspective represen...

human alpha 1-antitrypsin (aat) cdna was obtained from hepg2 cell lines. after pcr and construction of expression vector ppiczα-aat, human aat was expressed in the yeast pichia pastoris (p.pastoris) in a secretary manner and under the control of inducible alcohol oxidase 1 (aox1) promoter. the amount of aat protein in medium was measured as 60 mg/l 72 hr after induction with methanol. results i...

Exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. These are incentives to reduce exhaust emissions to the barest minimum. Two major cities in Ghana, Accra and Kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...
