Direct measurements bearing on the question of the nighttime heating mechanism in the ionosphere
(Elsevier, 1967-01)
Langmuir probe measurements of electron temperature and density were made in the upper F-region on two different occasions near local midnight. The experiments were carried out at Fort Churchill, Canada, and at Wallops ...
Measurement of fracture stress, young's modulus, and intrinsic stress of heavily boron-doped silicon microstructures
(Elsevier, 1989-12-10)
Heavily boron-doped silicon microstructures fabricated using deep-boron diffusions and boron etch-stops have been widely used in a variety of integrated sensors and actuators. For many applications, having knowledge of the ...
Desorption by ultrasound: Phenol on activated carbon and polymeric resin
(Wiley Subscription Services, Inc., A Wiley Company, 1998-07)
An experimental feasibility study of using ultrasound to accomplish the dificult desorption of phenol from activated carbon and polymeric resin adsorbents is discussed. The desorption rates of activated carbon were found ...
COMMENT: Reply to a comment by R Newton
(IOP Publishing Ltd, 1989-06-01)
Following Newton's comment (see ibid., vol.5, p.437 (1989)), the author points out that: (1) the major contribution of his previous paper (see ibid., vol.4, p.549 (1988)) is the generalised fast Cholesky algorithm, not the ...
Model calculations of the dayside ionosphere of Venus
(Elsevier, 1981)
Model calculations of the dayside ionosphere of Venus are presented. The coupled continuity and momentum equations were solved for O2+, O+, CO2+, C+, N+, He+, and H+ density distributions, which are compared with measurements ...
Ganglion cell acuity in hooded rats
(Elsevier, 1982)
Previous measurements of retinal ganglion cell acuity in hooded rats have differed significantly from behavioral tests of visual acuity. One possible source of this discrepancy is examined--that light deprivation in early ...
Orientation-dependent phase equilibria in in_1-x Ga_x As: A model including surface energies
(Elsevier, 1985)
Orientation-dependent growth phenomena have been observed for liquid-phase epitaxial In1-xGaxAs and other ternary and quaternary III-V semiconductors. The data cannot be explained by existing regular solution phase equilibria ...
Why ring regenerative amplification (regen)?
(Springer-Verlag, 2002-06)
We show that ring cavity regenerative amplifiers (regens) have distinct advantages over the linear ones for applications in chirped pulse amplification. Larger energy, better contrast and better isolation from the oscillator ...
Stratified least fixpoint logic
(Elsevier, 1994-08-29)
Stratified least fixpoint logic, or SLFP, characterizes the expressibility of stratified logic programs and, in a different formulation, has been used as a logic of imperative programs. These two formulations of SLFP are ...
