A systems approach to the management of large projects: Review of NASA experience with societal implications
The application of the NASA type management approach to achieve objectives in other fields is considered. The NASA management outlook and the influences of the NASA environment are discussed along with project organization and management, and applications to socio-economic projects
Entanglement of identical particles and reference phase uncertainty
We have recently introduced a measure of the bipartite entanglement of
identical particles, E_P, based on the principle that entanglement should be
accessible for use as a resource in quantum information processing. We show
here that particle entanglement is limited by the lack of a reference phase
shared by the two parties, and that the entanglement is constrained to
reference-phase invariant subspaces. The super-additivity of E_P results from
the fact that this constraint is weaker for combined systems. A shared
reference phase can only be established by transferring particles between the
parties, that is, with additional nonlocal resources. We show how this nonlocal
operation can increase the particle entanglement.Comment: 8 pages, no figures. Invited talk given at EQIS'03, Kyoto, September,

GREMEX update (Goddard research engineering management exercise)
Management simulation techniques offer training in management problems. Exercise was developed to provide experience in research and development project decision making from management rather than technological perspective. Program and documentation have been revised innumerable times in past. Described report is revised version as it exists to date
Tradeoff between extractable mechanical work, accessible entanglement, and ability to act as a reference system, under arbitrary superselection rules
Superselection rules (SSRs) limit the mechanical and quantum processing
resources represented by quantum states. However SSRs can be violated using
reference systems to break the underlying symmetry. We show that there is a
duality between the ability of a system to do mechanical work and to act as a
reference system. Further, for a bipartite system in a globally symmetric pure
state, we find a triality between the system's ability to do local mechanical
work, its ability to do ``logical work'' due to its accessible entanglement,
and its ability to act as a shared reference system.Comment: 5 pages, no figures. Extended resubmitted version. Slightly modified
title. Transferred to PR
GREMEX-A new management training concept
Goddard Research Engineering Management Exercise provides experience in R&D project decision making from a management rather than technological view. The participant directs a hypothetical project presented in the management simulation technique. He uses old or new methods without concern for rewards or penalties existing in real life
