Abstract The cosmic ray production of new atoms in m atter is the basis of radiocarbon dating. In this case the atom is carbon of mass fourteen made from the most abundant atom in air—nitrogen of mass fourteen. Radiocarbon— carbon-14, 14C—lasts 8300 years on the average (see note on radioactive decay on p.

Stochastic Scheduling with Release Dates and Due Dates
Operations Research, 1983We consider stochastic scheduling problems in which the processing times of jobs are independent exponentially distributed random variables, the release dates are random variables with an arbitrary joint distribution, and the due dates are random variables with a joint distribution that satisfies certain conditions.

Although most historians and art historians consider the radiocarbon dating technique not to be very precise by their criteria, the method has gained much importance over the last decades. Radiocarbon dating is increasingly used in the field of textile research and old polychrome statues, but also objects made of ivory, stucco, paper, and parchment are
