Wire electric-discharge machining and other fabrication techniques

Wire electric discharge machining and extrude honing were used to fabricate a two dimensional wing for cryogenic wind tunnel testing. Electric-discharge cutting is done with a moving wire electrode. The cut track is controlled by means of a punched-tape program and the cutting feed is regulated according to the progress of the work. Electric-discharge machining involves no contact with the work piece, and no mechanical force is exerted. Extrude hone is a process for honing finish-machined surfaces by the extrusion of an abrasive material (silly putty), which is forced through a restrictive fixture. The fabrication steps are described and production times are given

Disentangling religion and culture: americanizing Islam as the price of assimilation

This essay is an exploration into the social inevitabilities of culture shifts within the American Muslim community’s self-understanding of their faith. Rather than a theological explication of the reasons why and why not Islam may or can or will not assimilate in America, our approach will be strictly sociological thereby side-stepping the intricate dialectic of theological niceties in deference to the social realities of culture change. As a social psychologist, my duty is to acknowledge the inevitabilities of behavioral shifts brought about due to social and cultural pressures resulting from immigration into an alien cultural weltanschauung, i.e., worldview. Therefore in this essay, we will explicate the meaning and nature of de-ethnicization and re-enculturation as we endeavor to disentangle religion from culture, recognizing that much of what goes under the flag of religious orthodoxy is really culturally-mandated behavior and worldview. The assimilation process, however, will bear heavily upon the necessity for Muslim clergy in America to become professional by Western standards and we will in the process explore the complexities of religious secularism as a way of becoming an “American” Muslim. Finally, we will suggest liturgical and architectural “adjustments” to Western modes of public worship while indicating linguistic niceties which will prove helpful in the assimilation process which we have chosen here to call the “Islamicization of America”

Preliminary design of an Earth-based debris detection system using current technology and existing installations

A simple instrument based on present-epoch technology for optical detection of orbital debris is described. The limits of detectability at various altitudes and under different operating conditions for this system are assessed. The kinds of information which can be deduced from this data are examined. Optimal systems for debris detection are discussed. Alternatives and possible improvements from new technologies are also considered

Summary of airport technology needs

The need for improvement in airport noise assessment methodology is summarized and specific investigations of the relationship between noise level and individual and community response outlined
