The low-noise read-out electronics of the experiment
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000Abstract The low-noise read-out electronics for the rhenium experiment is presented. We have built three source followers with two matched J-FET in cascode configuration. These are cooled at about 150 K in a thermally shielded box in the inner vacuum chamber of the dilution cryostat.

Noise and Reading Performance in an Open Space School
The Journal of Educational Research, 1979AbstractParents and educators have expressed fears that high noise levels in open space schools may interfere with academic achievement. This investigation compared the reading comprehension of sixty fourth grade students in an open space school during periods of quiet and periods of naturally occurring background noise.

Office noise and illumination effects on reading comprehension
Journal of Environmental Psychology, 1990Abstract This study investigated the effects of illumination, office noise, gender and locus of control on reading comprehension. In the experiment 48 male and 52 female subjects completed a reading comprehension test in a between-subjects 3 × 2 × 2 (illuminance × noise × gender) randomized block design. Three levels of ambient illumination were used:

The effect of a noise abatement program on reading ability
Journal of Environmental Psychology, 1981A school was selected for the testing of the effects of resilient rubber pads as noise control devices on a nearby elevated rail track. In addition three school classrooms received acoustical treatment to the ceilings. Teachers and students reported a quieter atmosphere after installation of the pads.

Analysis of large-signal noise in read oscillators
Solid-State Electronics, 1972Abstract A large-signal noise theory to second order in the r.f. amplitude is developed for the noise generator of an IMPATT oscillator of Read-type. The coefficient for the second order term in the noise spectrum is calculated as function of frequency.

A Portable, Direct-Reading Microwave Noise Generator
Proceedings of the IRE, 1952This paper discusses the factors which influenced the design of a directly calibrated portable microwave noise source, utilizing a fluorescent lamp. The variation of the noise power output and the impedance match as a function of the operating temperature are considered, and the portable unit is described.
