Augmented Method to Improve Thermal Data for the Figure Drift Thermal Distortion Predictions of the JWST OTIS Cryogenic Vacuum Test
The JWST Optical Telescope Element (OTE) assembly is the largest optically stable infrared-optimized telescope currently being manufactured and assembled, and is scheduled for launch in 2018. The JWST OTE, including the 18 segment primary mirror, secondary mirror, and the Aft Optics Subsystem (AOS) are designed to be passively cooled and operate near 45K. These optical elements are supported by a complex composite backplane structure. As a part of the structural distortion model validation efforts, a series of tests are planned during the cryogenic vacuum test of the fully integrated flight hardware at NASA JSC Chamber A. The successful ends to the thermal-distortion phases are heavily dependent on the accurate temperature knowledge of the OTE structural members. However, the current temperature sensor allocations during the cryo-vac test may not have sufficient fidelity to provide accurate knowledge of the temperature distributions within the composite structure. A method based on an inverse distance relationship among the sensors and thermal model nodes was developed to improve the thermal data provided for the nanometer scale WaveFront Error (WFE) predictions. The Linear Distance Weighted Interpolation (LDWI) method was developed to augment the thermal model predictions based on the sparse sensor information. This paper will encompass the development of the LDWI method using the test data from the earlier pathfinder cryo-vac tests, and the results of the notional and as tested WFE predictions from the structural finite element model cases to characterize the accuracies of this LDWI method
Active X-ray Optics for Generation-X, the Next High Resolution X-ray Observatory
X-rays provide one of the few bands through which we can study the epoch of
reionization, when the first galaxies, black holes and stars were born. To
reach the sensitivity required to image these first discrete objects in the
universe needs a major advance in X-ray optics. Generation-X (Gen-X) is
currently the only X-ray astronomy mission concept that addresses this goal.
Gen-X aims to improve substantially on the Chandra angular resolution and to do
so with substantially larger effective area. These two goals can only be met if
a mirror technology can be developed that yields high angular resolution at
much lower mass/unit area than the Chandra optics, matching that of
Constellation-X (Con-X). We describe an approach to this goal based on active
X-ray optics that correct the mid-frequency departures from an ideal Wolter
optic on-orbit. We concentrate on the problems of sensing figure errors,
calculating the corrections required, and applying those corrections. The time
needed to make this in-flight calibration is reasonable. A laboratory version
of these optics has already been developed by others and is successfully
operating at synchrotron light sources. With only a moderate investment in
these optics the goals of Gen-X resolution can be realized.Comment: Enhanced version of SPIE presentation. 11 pages, 5 figure
The Technological culture of war
The article proceeds from the argument that war is a social institution and not a historical inevitability of human interaction,
that is, war can be “unlearned.” This process involves deconstructing/dismantling war as an institution in
society. An important step in this process is to understand the philosophical and cultural bases on which technology
is employed as “tools” of war. The article focuses on such questions as, Is technology just viewed as instruments in
the hand of its human masters in war? Does technology take on an autonomous role in war? How should we assess
the impact of context (political, economic, and cultural) of technology when employed in war? By exploring these
points, the article hopes to provide input into the discussion on the control of war technologies and ultimately the dismantling
of war as an institution in society
Case Fatality Rates Based on Population Estimates of Influenza-Like Illness Due to Novel H1N1 Influenza: New York City, May–June 2009
BACKGROUND: The public health response to pandemic influenza is contingent on the pandemic strain's severity. In late April 2009, a potentially pandemic novel H1N1 influenza strain (nH1N1) was recognized. New York City (NYC) experienced an intensive initial outbreak that peaked in late May, providing the need and opportunity to rapidly quantify the severity of nH1N1. METHODS AND FINDINGS: Telephone surveys using rapid polling methods of approximately 1,000 households each were conducted May 20-27 and June 15-19, 2009. Respondents were asked about the occurrence of influenza-like illness (ILI, fever with either cough or sore throat) for each household member from May 1-27 (survey 1) or the preceding 30 days (survey 2). For the overlap period, prevalence data were combined by weighting the survey-specific contribution based on a Serfling model using data from the NYC syndromic surveillance system. Total and age-specific prevalence of ILI attributed to nH1N1 were estimated using two approaches to adjust for background ILI: discounting by ILI prevalence in less affected NYC boroughs and by ILI measured in syndromic surveillance data from 2004-2008. Deaths, hospitalizations and intensive care unit (ICU) admissions were determined from enhanced surveillance including nH1N1-specific testing. Combined ILI prevalence for the 50-day period was 15.8% (95% CI:13.2%-19.0%). The two methods of adjustment yielded point estimates of nH1N1-associated ILI of 7.8% and 12.2%. Overall case-fatality (CFR) estimates ranged from 0.054-0.086 per 1000 persons with nH1N1-associated ILI and were highest for persons>or=65 years (0.094-0.147 per 1000) and lowest for those 0-17 (0.008-0.012). Hospitalization rates ranged from 0.84-1.34 and ICU admission rates from 0.21-0.34 per 1000, with little variation in either by age-group. CONCLUSIONS: ILI prevalence can be quickly estimated using rapid telephone surveys, using syndromic surveillance data to determine expected "background" ILI proportion. Risk of severe illness due to nH1N1 was similar to seasonal influenza, enabling NYC to emphasize preventing severe morbidity rather than employing aggressive community mitigation measures
