A metastable phase of NbN with superconducting T c =16.4 K was reported recently by Treece and collaborators. The reported structure of the thin film sample deviates from the rocksalt (B1) NbN structure with 25% ordered vacancies on each sublattice (space group Pm3m) and a lattice constant of 4.442Å. Using full potential electronic structure methods, we contrast the electronic structure with th...

knowledge management is a process that has been recently generated as an activity which is very important in the dynamic environment, and in the competitive scene. we believe that km is a process which its organizational knowledge is created from the individual knowledge of the members of the organization. the relevant studies have indicated that organizing based on work teams could be consider...

Business Process Management (BPM) systems provide a broad range of facilities to enact and manage operational business processes. Ideally, these systems should provide support for the complete BPM life-cycle: (re)design, configuration, execution, control, and diagnosis of processes. However, based on an extensive evaluation of the FileNet P8 BPM Suite, we show that existing BPM tools are unable...

During the visual approach to landing of a fixed wing aircraft, a human pilot bases control and timing of subsequent maneuvers mainly on the out-the-window view, as there is not sufficient time to read all instruments. The skill of making smooth and soft landings is acquired mainly through experience. Research has been done to identify the most important features in the visual scene (cues) for ...
