To that end, a modular power management and distribution system (PMAD) is proposed which will help transition the aerospace industry towards an assembly line approach to building spacecraft. The modular system is based on an innovative DC voltage boost converter called the Series Connected Boost Regulator (SCBR). The SCBR uses existing DC-DC converters and adds a unique series connection. This simple modification provides the SCBR topology with many advantages over existing boost converters. Efficiencies of 94-98%, power densities above 1,000We/kg, and inherent fault tolerance are just a few of the characteristics presented. Limitations of the SCBR technology are presented, and it is shown that the SCBR makes an ideal photovoltaic array regulator. A modular design based on the series connected boost unit is outlined and functional descriptions of the components are given. Unclas sified Unclas sift ed

Such a workforce does not exist in Australia today, but one could be cultivated over the next 15 to 20 years under the right circumstances. By collaborating with foreign design partners rather than relying exclusively on a domestic design workforce, Australia could shorten the duration and lessen the costs of designing a new submarine.

It will do so by minimizing the need to build up a logistics stockpile ashore, reducing the operational demand for sealift and airlift assets, and permitting forward positioning of joint forces for immediate employment. The cornerstone of sea-based logistics on the brigade scale is the Maritime Pre-positioning Force and its future version, the MPF(F). The Maritime Pre-positioning Force currently consists of three forward deployed squadrons of maritime pre-positioning ships, each with five or six vessels with weapons, supplies, and equipment sufficient to support a force about the size of a Marine Expeditionary Brigade for up to 30 days. The MPF(F) will be composed of multiple ship types designed to support a Marine Expeditionary Brigade and provide functions not currently provided by the MPF, such as at-sea arrival, assembly, sustainment, reconstitution, and redeployment of Expeditionary Forces, as well as Expeditionary Strike Group interoperability. Current plans call for an MPF(F) squadron comprising three large-deck amphibious ships, three Mobile Landing Platform transport ships, and eight cargo ships.

Juhâsz on a napkin in Canter's restaurant in Pittsburgh, Pennsylvania. We agreed that if the proposition could be proven it would have some elegant applications and although it required a slight change before it could be proven, hopefully those expectations will be realized in this note.

We shall be interested almost exclusively with separation and disconnectedness conditions in the Q-topology. For instance, we shall show that the Q-topology for a non-discrete completely regular space is a nondiscrete zero-dimensional space in every enlargement. The reader is assumed to know what is meant by an enlargement in the sense of Robinson, what is meant by an ultraproduct enlargement, and to be familiar with the rudiments of non-standard analysis. A good short introduction is sections 1-6 of [6]. We generalize the Q-topology somewhat by introducing the notion of a *topological space and the Q-topology for a *topological space. This will help in dealing with subspaces and will give a slightly simpler notation. Definition 1: A *topological space in a non-standard model *9W is a pair {X,%), where X is an internal set in *9W and$ ^P(X) is an internal family of sets closed under *finite intersections and internal unions, and which contains 0 and X. If (X,%) is a topological space in a model 3W, then *(X,$) = (*X,*$) is a (standard) *topological space in any enlargement *9W of 9W. If © is an infinite collection of topological spaces in a model 3W, then *© contains a non-standard *topological space for any enlargement *9W of 9W.
