An accurate characterization of CRT Monitor (I) verifications of past studies and clarifications of Gamma
(The Optical Society of Japan, co-published with Springer-Verlag GmbH, 2001-09)
CRT monitors are widely used to view images on the Internet. The color images on the computer graphic display can be printed out or displayed on other monitors through the Internet, and color matching between the original ...
Experimental investigation of the resistance in thin superconducting films of niobium-germanium
(American Institute of Physics, 1980-01-15)
We discuss the resistance of thin superconducting films of amorphous niobium-germanium below the BCS thermodynamic transition temperature as determined by measurements of the heat capacity. This resistance is shown to be ...
Acousto-optic star couplers for routing and broadcasting in local area networks
(Wiley Periodicals - Microwave and Optical Technology Letters, 1993-10-28)
Acousto-optic deflectors are introduced to be used as star couplers that perform broadcasting and routing in local area networks. Configurations for both single-wavelength and multiwavelength broadcast-and-select networks ...
Investigation of a pulse compression technique for medical ultrasound: a simulation study
(Springer Berlin / Heidelberg, 1994-03)
Pulse compression techniques that are capable of producing a large signal-to-noise (SNR) enhancement, have been used successfully in many different fields. For medical applications, frequency-dependent attenuation in soft ...
Paradoxical shifts in human color sensitivity caused by constructive and destructive interference between signals from the same cone class
(Cambridge University Press, 2006-05)
Paradoxical shifts in human color (spectral) sensitivity occur on deep-red (658 nm) background fields. As the radiance of the deep-red background is increased from low to moderate levels, the spectral sensitivity for ...
The homomorphic image of a Tn-semigroup
(Springer New York, 1972-12)
Methods for characterizing CRT displays
(Elsevier Science B.V., Amsterdam, 1996-05)
Computer-controlled CRT displays can be described by a two-stage model. The first stage consists of a linear transformation matrix relating radiometric scalars of each channel with either spectral radiance or tristimulus ...
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 ...
Spatial averaging in the beam of a piston transducer
(Elsevier Science, 2001-05)
This paper presents a theoretical analysis of the spatially averaged free-field responses of phase-sensitive and phase-insensitive receivers centered in the beam of a harmonically excited piston transmitter. The responses ...
Development of a flow boiling map for subcooled and saturated flow boiling of different fluids inside circular tubes
(American Society of Mechanic Engineers, 1991-02)
The thermal behavior of a flow boiling system is represented by a flow boiling map to illustrate visually the relationships among various system parameters. An earlier flow boiling map Collier (1981) does not include the ...
