    Improvements in Ross type astrometric objectives (1971)
    In:  CASI
    Details
    Publication Date: 2005-11-30
    Description: It is shown that aspheric deformations of the first and fourth elements of the four element Ross objective can be introduced to permit one to obtain improved color corrections for astrometric purposes. The usual monochromatic aberrations are as well corrected as for the standard Ross lens. In addition, one can eliminate or reduce additional aberrations, such as secondary spectrum, chromatic spherical aberration, chromatic coma and chromatic distortion. The resulting objectives are suitable for use as intermediate and long focus astrometric objectives covering large angle fields.

    Marine research using data from TOPEX/Poseidon (1991)
    In:  CASI
    Details
    Publication Date: 2006-06-13
    Description: The Proudman Oceanographic Laboratory (POL), the Institute of Oceanographic Sciences Deacon Laboratory (IOSDL), and the British National Space Centre (BNSC) plan to use radar altimeter data from the TOPEX/POSEIDON mission in five main areas of research. These are: (1) investigation of variations in Southern Ocean sea levels and circulation; (2) related numerical modeling and data assimilation; (3) global and regional ocean tides; (4) North Sea and northeast Atlantic studies; and (5) winds and waves. Each one of these topics is described briefly below while more information can be extracted from the United Kingdom response to the TOPEX/POSEIDON Announcement of Opportunity.

    'Oxide-free' tip for scanning tunneling microscopy (1987)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: A new tip for scanning tunneling microscopy and a tip repair procedure that allows one to reproducibly obtain atomic images of highly oriented pyrolytic graphite with previously inoperable tips are reported. The tips are shown to be relatively oxide-free and highly resistant to oxidation. The tips are fabricated with graphite by two distinct methods.

    Aircraft and satellite measurement of ocean wave directional spectra using scanning-beam microwave radars (1985)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: A microwave radar technique for remotely measuring the vector wave number spectrum of the ocean surface is described. The technique which employs short-pulse, noncoherent radars in a conical scan mode near vertical incidence, is shown to be suitable for both aircraft and satellite application, the technique was validated at 10 km aircraft altitude, where we have found excellent agreement between buoy and radar-inferred absolute wave height spectra.

    Rapid evolution of a Gulf Stream warm-core ring (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: Satellite images are used to show that major alterations in the structure of Gulf Stream warm-core rings can occur during very short periods of two to five days when an interaction with the Gulf Stream is particularly intense. The role of these interactions in the evolution of a ring are discussed.

    Mathematical models for film sensitivity measurements (1989)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: The quality of the pictorial record developed from photographic material depends on the composition of the material, the procedures used in its exposure and processing, as well as, the nature of the physical and temporal environment extant during the creation of the record. By holding many of the variables fixed, the effect of the two environmental parameters, namely temperature and aging are examined on the characteristic curve of a given film. Polynomial and exponential functions are evaluated as empirical formulas for the characteristic curve, and the sensitivity of derived coefficients to the selected parameters is assessed.

    The analysis of ocean optical data (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: A new oceanographic instrument to measure underwater optical, biological and physical properties simultaneously has been built and used extensively at sea. The Bio-Optical Profiling System (BOPS) was designed for the rapid acquisition of data to accommodate shipboard 'synoptic' sampling strategies, often in conjunction with concurrent aircraft and satellite sensors. The data rates and associated quantity of data from the BOPS are some orders of magnitude larger than those traditionally encountered in optical oceanography. The rapid acquisition of optical data in a wide range of environmental conditions requires new methodologies in ocean optical data analysis.

    What can earth tide measurements tell us about ocean tides or earth structure? (1978)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: Current experimental problems in Earth tides are reviewed using comparisons of tidal gravity and tilt measurements in Europe with loading calculations are examples. The limitations of present day instrumentation and installation techniques are shown as well as some of the ways in which they can be improved. Many of the geophysical and oceanographic investigations that are possible with Earth tide measurements are discussed with emphasis on the percentage accuracies required in the measurements in order to obtain new information about Earth or its oceans.
