High precision temperature controller for experimental cryostats

Cryogenics, 1969
Abstract A general purpose instrument is described which is capable of providing temperature control to better than 1 mK for long periods in a wide variety of cryogenic applications. The main first and second order effects contributing to temperature instability are taken into consideration.

Experimental evolutionary programming-based high-precision control

IEEE Control Systems, 1997
Conventional linear control schemes often fail to provide precise positioning of a control object under the influence of friction, deadzone, saturation, etc. This article proposes a high-precision control scheme for a precise point-to-point positioning system, called an X-Y table, even under the above-noted influences.

Experimental study of the precision of weighing

Mikrochemie Vereinigt mit Mikrochimica Acta, 1953
Aus den Ergebnissen von mehr als 200 Wagungen auf einer analytischen Waage von Ainsworth und 200 Wagungen auf einer mikrochemischen Waage von Kuhlmann wird geschlossen, das die Prazision derGausschen Doppelwagung jene der direkten Wagung unter Berucksichtigung der Lage des Nullpunktes der Waage um das Doppelte ubertrifft.

EXPERIMENTAL MEASUREMENT OF PRECISION BEARING DYNAMIC STIFFNESS

Journal of Sound and Vibration, 1997
Abstract Static stiffness measurement of precision bearing components by influence coefficients is complicated by the task of loading and measuring the baseline test fixture stiffness before including the bearing components. Furthermore, as the displacement of the bearing system is measured for various load conditions, the stiffness of high quality ...

Covering-based variable precision fuzzy rough sets with PROMETHEE-EDAS methods

Information Sciences, 2020
This paper proposes a reflexive fuzzy β -neighborhood operator by modifying Ma’s fuzzy β -neighborhood operators. Then, we use such an operator to build a covering-based variable precision fuzzy rough set (CVPFRS) model that can deal with the issue of ...

Aroma Extract Dilution Analysis. Precision and Optimal Experimental Design

Journal of Agricultural and Food Chemistry, 2002
The odor thresholds of 12 different compounds have been determined in an AEDA experiment using a panel composed of 8 individuals. Only in one case is the distribution of thresholds among judges significantly different from the log-normal. The cause of that departure from normality seems to be a cross adaptation rather than anosmia.

Evaluation of measurement precision in experimental methods

Measurement Techniques, 1965
The above method for evaluating the precision of measurements used in medicine can be applied to a wider range of measurements. It has only been possible, owing to the limited size of the article, to include in it an analysis of measurement accuracy, without dealing with other important problems, such as a comparison of various methods for their ...

Small‐Grain Precision Planter for Dryland Experimental Plots

Agronomy Journal, 1994
AbstractSmall‐grain stand establishment in research plots of the summer rainfall region of South Africa is a problem because of dry surface soil. A vacuum system plot planter was developed to meet these requirements. The planter has simple adjustments for changes in species, cultivars, seeding rate, row spacing, and fertilizer rate.
