NBS/NIST Gas Thermometry From 0 to 660 °C

In the NBS/NIST Gas Thermometry program, constant-volume gas thermometers, a unique mercury manometer, and a highly accurate thermal expansion apparatus have been employed to evaluate temperatures on the Kelvin Thermodynamic Temperature Scale (KTTS) that correspond to particular temperatures on the 1968 International Practical Temperature Scale (IPTS-68). In this paper, we present a summary of ...

Refining membership degrees obtained from fuzzy C-means by re-fuzzification

Fuzzy C-mean (FCM) is the most well-known and widely-used fuzzy clustering algorithm. However, one of the weaknesses of the FCM is the way it assigns membership degrees to data which is based on the distance to the cluster centers. Unfortunately, the membership degrees are determined without considering the shape and density of the clusters. In this paper, we propose an algorithm which takes th...

Effects of a novel ice-cooling technique on work in protective clothing at 28 degrees C, 23 degrees C, and 18 degrees C WBGTs.

This study tested a new ice cooling system that permits ice cooling system recharge without personal protective clothing removal. Six male volunteers (22.1 +/- 1.2 years) underwent tests with the new ice cooling system (COOL) and without (NOCL) at a moderate work rate (450 W) in three environments of 28, 23, and 18 +/- 1 degrees C wet bulb globe temperature. Walks at 28 degrees C were carried o...

Degrees of d. c. e. reals

A real is called c.e. if it is the halting probability of a prefix free Turing machine. Equivalently, a real is c.e. if it is left computable in the sense that L(α) = {q ∈ Q : q ≤ α} is a computably enumerable set. The natural field formed by the c.e. reals turns out to be the field formed by the collection of reals of the form α− β where α and β are c.e. reals. While c.e. reals can only be fou...

ON c - AND P - RECURSMLY ENUMERABLE DEGREES

Several problems in recursion theory on admissible o¡dinals (a -recursion theory) and recursion theory on inadmissible ordinals (B -recursion theory) are studied. Fruitful interactions betweenboth theories are stressed. In the fr¡stpart the admissible collapse is used in order to characterizefor some inadmissible B the structure of all p -recursively enumerable degrees asanaccumulationof struct...
