A hybrid process for recovering software architecture
A large portion of the software used in industry today is legacy software. Legacy systems often evolve into diicult to maintain systems whose original design has been lost or else no longer closely matches the actual structure of the system. In our paper 1 we present a \hybrid" process in which we combine extracted code facts and information derived from interviewing developers to determine the...
متن کاملIodine-129 and iodine-127 in seawater of the North Sea and precipitation from northern Germany
Atmospheric nuclear weapons tests, nuclear accidents, and emissions from reprocessing plants have changed the natural abundances of I (T1/2=15.7 Ma) in a sustainable manner. Mainly as a consequence of the I releases from the European reprocessing plants, I is in disequilibrium in all environmental compartments of the Western Europe. Surface water from the North Sea and the English Channel, whic...

متن کاملA review on speciation of iodine-129 in the environmental and biological samples.
As a long-lived beta-emitting radioisotope of iodine, (129)I is produced both naturally and as a result of human nuclear activities. At present time, the main part of (129)I in the environment originates from the human nuclear activity, especially the releases from the spent nuclear fuel reprocessing plants, the (129)I/(127)I ratios have being reached to values of 10(-10) to 10(-4) in the envir...
