Development Communication: 1. History and Theories
This entry includes three articles, each dealing with a different aspect of the subject: History and Theories Alternative Systems Projects
The first and third cover predominantly the Western (especially the U.S.) approach; the second raises some criticisms directed at both the theoretical and the practical limitations of the Western perspective and presents alternative views
One-arm exponent for critical 2D percolation
The probability that the cluster of the origin in critical site percolation
on the triangular grid has diameter larger than is proved to decay like
as
Values of Brownian intersection exponents III: Two-sided exponents
This paper determines values of intersection exponents between packs of
planar Brownian motions in the half-plane and in the plane that were not
derived in our first two papers. For instance, it is proven that the exponent
describing the asymptotic decay of the probability of
non-intersection between two packs of three independent planar Brownian motions
each is . More generally, the values of and \tx (w_1', ..., w_k') are determined for all ,
, and all
. The proof relies on the results derived in our
first two papers and applies the same general methods. We first find the
two-sided exponents for the stochastic Loewner evolution processes in a
half-plane, from which the Brownian intersection exponents are determined via a
universality argument
An evaluation of the total quality management implementation strategy for the advanced solid rocket motor project at NASA's Marshall Space Flight Center
An evaluation of the NASA's Marshall Space Flight Center (MSFC) strategy to implement Total Quality Management (TQM) in the Advanced Solid Rocket Motor (ASRM) Project is presented. The evaluation of the implementation strategy reflected the Civil Service personnel perspective at the project level. The external and internal environments at MSFC were analyzed for their effects on the ASRM TQM strategy. Organizational forms, cultures, management systems, problem solving techniques, and training were assessed for their influence on the implementation strategy. The influence of ASRM's effort was assessed relative to its impact on mature projects as well as future projects at MSFC
Space processing of chalcogenide glass
A program was conducted to develop the technique of space processing for chalcogenide glass, and to define the process and equipment necessary. In the course of this program, successful long term levitation of objects in a 1-g environment was achieved. Glass beads 4 mm diameter were containerless melted and fused together
Method of forming ultra thin film devices by vacuum arc vapor deposition
A method for providing an ultra thin electrical circuit integral with a portion of a surface of an object, including using a focal Vacuum Arc Vapor Deposition device having a chamber, a nozzle and a nozzle seal, depressing the nozzle seal against the portion of the object surface to create an airtight compartment in the chamber and depositing one or more ultra thin film layer(s) only on the portion of the surface of the object, the layers being of distinct patterns such that they form the circuit
