The Grand Compromise: The ANCSA Section 7(i) Settlement Agreement
In 1982, Alaska’s twelve regional Native corporations finalized and executed a settlement agreement ending a decade of litigation involving Section 7(i) of the Alaska Native Claims Settlement Act. The 121-page Settlement Agreement is complex and covers a number of issues. The Agreement annually governs the distribution of tens of millions in revenue shared between the regional corporations pursuant to Section 7(i). This Article reviews the history of the Settlement Agreement, with emphasis on the negotiations that led to it, as well as the legal challenges regarding the Agreement since its execution. This Article also reviews the Agreement, section-by-section, and provides insight from court cases, arbitration decisions, and other analysis of sections in the Agreement. Finally, this Article recommends that the twelve regions consider amending the Agreement to modernize it and address issues that have arisen since 1982 that were not anticipated by the drafters of the Agreement. This Article is a follow-on to ANCSA Section 7(I): $40 Million Per Word and Counting, which reviewed the history of Section 7(i)
Speed-of-light limitations in passive linear media
We prove that well-known speed of light restrictions on electromagnetic
energy velocity can be extended to a new level of generality, encompassing even
nonlocal chiral media in periodic geometries, while at the same time weakening
the underlying assumptions to only passivity and linearity of the medium
(either with a transparency window or with dissipation). As was also shown by
other authors under more limiting assumptions, passivity alone is sufficient to
guarantee causality and positivity of the energy density (with no thermodynamic
assumptions). Our proof is general enough to include a very broad range of
material properties, including anisotropy, bianisotropy (chirality),
nonlocality, dispersion, periodicity, and even delta functions or similar
generalized functions. We also show that the "dynamical energy density" used by
some previous authors in dissipative media reduces to the standard Brillouin
formula for dispersive energy density in a transparency window. The results in
this paper are proved by exploiting deep results from linear-response theory,
harmonic analysis, and functional analysis that had previously not been brought
together in the context of electrodynamics.Comment: 19 pages, 1 figur
Development and evaluation of a prototype in-flight instrument flight rules (IFR) procedures trainer
An in-flight instrument flight rules (IFR) procedures trainer capable of providing simulated indications of instrument flight in a typical general aviation aircraft independent of ground based navigation aids was developed. The IFR navaid related instruments and circuits from an ATC 610J table top simulator were installed in a Cessna 172 aircraft and connected to its electrical power and pitot static systems. The benefits expected from this hybridization concept include increased safety by reducing the number of general aviation aircraft conducting IFR training flights in congested terminal areas, and reduced fuel use and instruction costs by lessening the need to fly to and from navaid equipped airports and by increased efficiency of the required in-flight training. Technical feasibility was demonstrated and the operational feasibility of the concept was evaluated. Results indicated that the in-flight simulator is an effective training device for teaching IFR procedural skills
Rapid consolidation of powdered materials by induction hot pressing
A rapid hot press system in which the heat is supplied by RF induction to rapidly consolidate thermoelectric materials is described. Use of RF induction heating enables rapid heating and consolidation of powdered materials over a wide temperature range. Such rapid consolidation in nanomaterials is typically performed by spark plasma sintering (SPS) which can be much more expensive. Details of the system design, instrumentation, and performance using a thermoelectric material as an example are reported. The Seebeck coefficient, electrical resistivity, and thermal diffusivity of thermoelectric PbTe material pressed at an optimized temperature and time in this system are shown to agree with material consolidated under typical consolidation parameters
