A. Paul Sigurd\u27s Decision

In lieu of an abstract, below is the essay\u27s first paragraph. Well, son, I don\u27t think anyone really knew how he got it. Some said it was always his and that he was always there. Yet others said that he inherited it from his father. And many be1ieved that it was given to him by an impulsive woman - the Hester Prynne type - who, being in dire straits, had to get rid of it. A few even said that he built it himself when lie was a young man. Me? I never cared how he got it; the fact was that he had it and he was there. But I must confess I always wondered why, I mean with no boats coming into the harbor anymore. And did you know that he used to paint it white every spring? And that he used to put the light on every night? Every night it could be seen from the mainland. Going around and around and around. But why? No boats had come into the harbor for nearly twenty years

NTF: Soldering Technology Development for Cryogenics

The advent of the National Transonic Facility (NTF) brought about a new application for an old joining method, soldering. Soldering for use at cryogenic temperatures requires that solders remain ductile and free from tin-pest (grey tin), have toughness to withstand aerodynamic loads associated with flight research, and maintain their surface finishes. Solders are used to attach 347 Stainless-Steel tubing in surface grooves of models. The solder must fill up the gap and metallurgically bound to the tubing and model. Cryogenic temperatures require that only specific materials for models can be used, including: Vasco Max 200 CVM, lescalloy A-286 Vac Arc, pH 13-8 Mo. Solders identified for testing at this time are: 50% Sn - 49.5% Pb - 0.5% Sb, 95% Sn - 5% Sb, 50% In 50% Pb, and 37.5% Sn - 37.5% Pb - 25% In. With these materials and solders, it is necessary to determine their solderability. After solderability is determined, tube/groove specimens are fabricated and stressed under cryogenic temperatures. Compatible solders are then used for acutual models

Formulation of the linear model from the nonlinear simulation for the F18 HARV

The F-18 HARV is a modified F-18 Aircraft which is capable of flying in the post-stall regime in order to achieve superagility. The onset of aerodynamic stall, and continued into the post-stall region, is characterized by nonlinearities in the aerodynamic coefficients. These aerodynamic coefficients are not expressed as analytic functions, but rather in the form of tabular data. The nonlinearities in the aerodynamic coefficients yield a nonlinear model of the aircraft's dynamics. Nonlinear system theory has made many advances, but this area is not sufficiently developed to allow its application to this problem, since many of the theorems are existance theorems and that the systems are composed of analytic functions. Thus, the feedback matrices and the state estimators are obtained from linear system theory techniques. It is important, in order to obtain the correct feedback matrices and state estimators, that the linear description of the nonlinear flight dynamics be as accurate as possible. A nonlinear simulation is run under the Advanced Continuous Simulation Language (ACSL). The ACSL simulation uses FORTRAN subroutines to interface to the look-up tables for the aerodynamic data. ACSL has commands to form the linear representation for the system. Other aspects of this investigation are discussed

Lawyers in the Shadow of the Regulatory State: Transnational Governance on Business and Human Rights

Lawyers are beginning to play an important role in strengthening the system of transnational governance that regulates business and human rights. In setting the background to our discussion of lawyers’ role in this context, Part I of this Article provides a general overview of the emergence of the transnational governance regime. Part II then describes some of the governance instruments that attempt to prevent and rectify the adverse human rights impacts of business activities. Part III discusses the extent to which lawyers are advising their business clients on human rights issues, the factors that may inhibit or encourage the provision of such advice, and how the lawyers who are raising these issues are framing these discussions with their clients. Finally, Part IV suggests further areas of inquiry that may enrich our understanding of the role that lawyers can play in helping construct a transnational governance regime on business and human rights
