The Independent Detector Testing Laboratory (IDTL) is jointly operated by the Space Telescope Science Institute (STScI) and the Johns Hopkins University (JHU), and is assisting the James Webb Space Telescope (JWST) mission in choosing and operating the best near-infrared detectors. The JWST is the centerpiece of the NASA Office of Space Science theme, the Astronomical Search for Origins, and th...

We discuss far-UV (1500 Å) surface photometry and FUV–B color profiles for 8 E/S0 galaxies from images taken with the Ultraviolet Imaging Telescope, primarily during the Astro-2 mission. In three cases, the FUV radial profiles are more consistent with an exponential than a de Vaucouleurs function, but there is no other evidence for the presence of a disk or of young, massive stars. In all cases...

A fuzzy-logic "performance control" system, providing envelope protection and direct command of airspeed, vertical velocity, and turn rate, was evaluated in a reconfigurable general aviation simulator (configured as a Piper Malibu) at the FAA Civil Aerospace Medical Institute. Performance of 24 individuals (6 each of high-time pilots, low-time pilots, student pilots, and nonpilots) was assessed...

Considerable interest has developed in recent years concerning the composition of the bacterial cell at a macromolecular level (Rodenberg, 1958; Wagan et al., 1958; Hess et al., 1957). Schachman et al. (1952) were apparently the first workers to study the sedimentation behavior of extracts obtained from disrupted microbial cells. These workers used a variety of methods to rupture the cells. The...

A cooperative effort between the U.S. Air Force Research Laboratory, Nova Research, Inc., the Raytheon Infrared Operations (RIO) and Optics 1, Inc. has successfully produced a miniature infrared camera system that offers significant realtime signal and image processing capabilities by virtue of its modular design. This paper will present an operational overview of the system as well as results ...

Typically, relation extraction models are trained to extract instances of a relation ontology using only training data from a single language. However, the concepts represented by the relation ontology (e.g. ResidesIn, EmployeeOf) are language independent. The numbers of annotated examples available for a given ontology vary between languages. For example, there are far fewer annotated examples...

Many product development programs contain multiple integrated product teams (IPTs) and functional support groups. Interteam information dependencies greatly affect program success. Organization integration has thus become an issue of increasing interest. This paper focuses on the realm of team interdependence and categorizes and explores several integrative mechanisms (IMs) that facilitate inte...

In This Issue This focus section offers reports from Asia and North America on corporate-wide implementations of software process improvement programs guided by process standards such as ISO 9000-3 and the Capability Maturity Model. 4–6 Unfortunately , a paper describing a successful corporate wide program in a European company was withdrawn just as this issue was being sent to the printer. The...

The environmental impacts of alternatives to ozone depleting solvent cleaners wereexaminedin this investigation. The focus of the program was to identify alternative cleanerswithout ozone depleting potential that would meet Raytheon’s needs for the cleaning of CircuitCard Assemblies (CCA’s). Technologies evaluated were saponified aqueous cleaning systemsand semi-aqueous ...

Conventional access control solutions rely on a single authentication to verify a user’s identity but do nothing to ensure the authenticated user is indeed the same person using the system afterwards. Without continuous monitoring, unauthorized individuals have an opportunity to “hijack” or “tailgate” the original user’s session. Continuous authentication attempts to remedy this security loopho...
