We investigate the kinetic roughening of Ar+ ion-sputtered Pd(001) surface both experimentally and theoretically. In situ real-time x-ray reflectivity and in situ scanning tunneling microscopy show that nanoscale adatom islands form and grow with increasing sputter time t. Surface roughness W(t) and lateral correlation length xi(t) follow the scaling laws W(t) approximately t(beta) and xi(t) approximately t(1/z) with the exponents beta approximately 0.20 and 1/z approximately 0.20, for an ion be

Current technology innovation or new product development project is composed of various process elements that conduct researches on fundamental technologies. However, with the effects of PERT and CPM, the greater part of the existing project management researches have only focused on the resource allocation and scheduling. But in the multi-project environment, priorities between technology elements need to be considered. Furthermore, a disagreement of opinion between project managers and researc
