Dependence on Reynolds number of high-order moments of velocity derivatives in isotropic turbulence [PDF]

open access: yes, 1970
The results of a heuristic model of the fine scale structure of homogeneous turbulence are presented. Predictions are made about the way in which flatness and skewness factors of arbitrary order depend upon the Reynolds number of the ...

A family of trees with no uncountable branches [PDF]

open access: yes, 2004
We construct a family of 2 ℵ1 trees of size ℵ1 and no uncountable branches that in a certain way codes all ω1sequences of infinite subsets of ω. This coding allows us to conclude that in the presence of the club guessing between ℵ1 and ℵ0, these trees ...

How Many Closed Structures does the Construct PRAP Admit? [PDF]

open access: yes, 2001
We will prove that the topological construct PRAP, introduced by E. and R. Lowen in [9] as a numerification supercategory of the construct PRTOP of convergence spaces and continuous maps, admits a proper class of monoidal closed structures.

Banach's fixed point theorem for partial metric spaces [PDF]

open access: yes, 2004
In 1994, S.G. Matthews introduced the notion of a par- tial metric space and obtained, among other results, a Banach contraction mapping for these spaces. Later on, S.J.

Some Comments on Edelstein’s Fixed Point Theorems in ν-Generalized Metric Spaces [PDF]

open access: yes, 2018
We study deeply two fixed point theorems in n-generalized metric spaces. The two theorems are generalizations of the famous, Edelstein’s fixed point theorem in compact metric ...

Descriptive Sets and the Topology of Nonseparable Banach Spaces [PDF]

open access: yes, 2001
This paper was extensively circulated in manuscript form beginning in the Summer of 1989. It is being published here for the first time in its original form except for minor corrections, updated references and some concluding ...

On weakly bisequential spaces [PDF]

open access: yes, 2000
summary:Weakly bisequential spaces were introduced by A.V. Arhangel'skii [1], in this paper. We discuss the relations between weakly bisequential spaces and metric spaces, countably bisequential spaces, Fréchet-Urysohn ...

The distribution, abundance, and ecology of larval tunas from the entrance to the Gulf of California [PDF]

open access: yes, 1970
ENGLISH: This study is based on collections of larvae of Thunnus albacares, Euthynnus llneatus, and Auxis sp. obtained from surface and oblique net tows made during seven cruises, each along a comparable track in the entrance of the Gulf of California ...

Signal conditioner circuit for photomultiplier tube [PDF]

open access: yes, 1970
Miniaturized circuit improves measurement of radiation dose absorbed in a scintillation crystal. The temperature coefficient of the field-effect transistor gate-source voltage in the isolation amplifier can be readily ...
