Heterodyne detection for Fiber Bragg Grating sensors
(Elsveier - Optics & Laser Technology, 2000-07)In this paper, we present a Fiber-Bragg-Grating-based temperature sensor. The technique employs heterodyne detection using two Fiber Bragg Gratings. One of the gratings is used as a reference (local oscillator) and the ... -
Heterogeneity and change in environmental strategy: Technological and political responses to climate change in the global automobile industry
(Stanford University Press, 2002)The formulation of strategy is generally treated as a rational process of matching corporate capabilities to market demands. But this does not always account well for the heterogeneity observed in corporate strategies ... -
Heterogeneous electron-transfer kinetics for some multiply bonded dirhenium complexes
(Elsevier: Journal of Electroanalytical Chemistry, 1985-12-10)Standard electrochemical rate constants kexob have been measured for the two sequential one-electron oxidations of triply-bonded dirhenium(II) complexes Re2X4(PR3)4, where X = Cl or Br, and PR3 = a monodentate tertiary ... -
A Heuristic for environmental values and ethics, and a psychometric instrument to measure adult environmental ethics and willingness to protect the environment
(2002)The need for instruments to objectively and deeply measure public beliefs concerning environmental values and ethics, and relationship to environmental protection led to a project to integrate analytical techniques from ... -

HI absorption in the gigamaser galaxy TXS 2226-184 and the relation between HI absorption and water emission
(American Astronomical Society, 2002-07-20)We report on the discovery of H i in absorption toward the gigamaser galaxy TXS 2226-184 using the Very Large Array. The absorption appears to consist of two components—one with a width of 125 km s^-1 and one broader (420 ... -
Hide & seek: objects of meaning
(2009-09-28)This thesis project is to design a philosophy to create mindfulness in the user of an object. To exemplify the philosophy, the secondary goal is to design objects with these attributes. Objects that encourage mindfulness ... -
Hierarchical approach to the optimal design of camera spectral sensitivities for colorimetric and spectral performance
(The Society for Imaging Science and Technology and the Society of Photo-Optical Instrumentation Engineers, 2003-01)The optimal design of spectral sensitivity functions for digital color imaging devices has been studied extensively. This paper analyzed the important requirements for designing sensor sensitivity functions. A hierarchical ... -
High accuracy imaging polarimetry with NICMOS
(Astronomical Polarimetry, 2009)The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2 - 1.5%. To better quantify and characterize this residual we obtained ... -
