Measurement Properties of Outcome Measures for Vitiligo

Archives of Dermatology, 2012
OBJECTIVE To summarize and critically appraise the evidence on the measurement properties of clinician-, patient-, and observer-reported outcomes, measuring any construct of interest in patients with all types of vitiligo. DATA SOURCES Electronic databases including PubMed (1948 to July 2011), OVID EMBASE (1980 to July 2011), and CINAHL (EBSCOhost ...

On Sequential Properties of Spaces of Measures

Mathematical Notes, 2021
A space is called an \(s_R\)-space if every sequentially continuous function on it, i.e., a function taking convergent sequences to convergent ones, is continuous.Then every sequentially continuous linear functional \(F\) on \(\mathcal{M}_r(X)\) (or on \(\mathcal{M}_d(X)\)) is continuous on \(\mathcal{M}_d(X)\).

Measuring the Empirical Properties of Sets

IEEE Transactions on Systems, Man, and Cybernetics, 1974
An important problem which frequently arises is the problem of measuring the degree to which a collection of objects has the empirical properties of its elements. Examples of this are found in the question of whether a network of switches is on or off, the degree to which a group of factories pollutes the air, and even the probability of success ...

On the statistical properties of the F-measure

Fourth International Conference onQuality Software, 2004. QSIC 2004. Proceedings., 2004
The F-measure - the number of distinct test cases to detect the first program failure - is an effectiveness measure for debug testing strategies. We show that for random testing with replacement, the F-measure will be distributed according to the geometric distribution. A simulation study examines the distribution of two adaptive random testing methods,

Founding properties on measurement

2010
Taking for granted an ontological standpoint independent of any empirical or epistemological perspective, philosophical theories of properties are actually quite rarely adopted in the knowledge representation community. The theory of qualities introduced in the DOLCE-CORE ontology [4] allows for representing different viewpoints on the world in a ...

On some properties of distance measures

Fuzzy Sets and Systems, 2001
Based on the axiom definition of distance measure, some new formulas of fuzzy entropy induced by distance measure and some new properties of distance measure are given. A characterization of a σ-distance measure is a metric defined on all fuzzy sets is obtained.

Some Measure-Theoretic Properties of Packing Measure

Periodica Mathematica Hungarica, 1998
This paper is an informal discussion of some fundamental measure-theoretic differences between the families of measures known as packing measures and Hausdorff measures. Two main issues of focus are, whether or not a set of infinite measure necessarily contains a subset of positive finite measure, and the question of Borel regularity.

Density Properties of Harmonic Measure

The Annals of Mathematics, 1995
Some metric properties of harmonic measure are studied in the paper. The basis of all considerations is the known formula \(f(x)= \int_{\partial \Omega} u dw_z\) which solves the Dirichlet problem \(\Delta f=0\) on \(\Omega \subset \mathbb{R}^n\), \(f=u\) on \(\partial \Omega\) and \(w_z\) a Borel probability measure on \(\partial \Omega\).

Thermal Properties Measurement of Materials

2018
The control of energy in the industrial sector and the reduction of consumption in the building sector will be key elements in the energy transition. In order to achieve these objectives it is necessary to use, in the first case, materials with energy performance adapted to their use and, in the second case, insulators, or rather super-insulators.

Tail Properties of Correlation Measures

Journal of Theoretical Probability, 2003
The authors study the tail properties of a class of Borel probability measures, called correlation measures. They show that (1) there exist correlation measures with exponentially decaying tail probabilities, and (2) roughly speaking, no correlation measure may have smaller tail probabilities than a Gaussian measure.
