Automated small sample calorimeter
Review of Scientific Instruments, 1975We describe an automated calorimetry system for measuring heat capacity in the range 1–35 K. The system employs an on-line computer for signal averaging and data reduction and is capable of performing rapid, accurate specific heat measurements on very small (1–100 mg) samples.

Small-Sample Confidence Intervals
Journal of the American Statistical Association, 1990Abstract In this article we present a technique for constructing one- or two-sided confidence intervals, which are second-order correct in terms of coverage, for either parametric or nonparametric problems. The construction is valid in the presence of nuisance parameters.

‘Student’ and Small Sample Theory
Journal of the American Statistical Association, 1958Abstract This year marks the Fiftieth Anniversary of the publication of “Student's” distribution. It is an appropriate time to reconsider the impact of this part of “Student's” work on the development of statistics.

Superfluorescence from Small Samples
Annalen der Physik, 1985AbstractThe initiation of superfluorescence from N ≦ 70 atoms distributed randomly over the volume of a sphere is investigated by numerical computations. When a specified atomic configuration is changed by performing similarity transformations the cooperation number approaches an asymptotic value ≫ 1 for mean distances ≲ λ/50.

Rheological measurements on small samples
1993Rheological measurements on small samples, but how small is small? In this chapter small means small enough for designing or interpreting bulk flow processes where the fluid may be considered a continuum. Thus, small means the smallest sample one can use that accurately represents the bulk rheological properties. In some cases the effect of sample size

Pediatrics, 1989
The believer in the law of small numbers practices science as follows: 1. He gambles his research hypotheses on small samples without realizing that the odds against him are unreasonably high. He overestimates power. 2. He has undue confidence in early trends (e.g., the data of the first few subjects) and in the stability ...
