Modeling pedestrian gap crossing index under mixed traffic condition

Journal of Safety Research, 2017
There are a variety of challenges faced by pedestrians when they walk along and attempt to cross a road, as the most recorded accidents occur during this time. Pedestrians of all types, including both sexes with numerous aging groups, are always subjected to risk and are characterized as the most exposed road users.

A mixed index approach to identifying hedonic price models

Regional Science and Urban Economics, 2006
Recent literature suggests identifying house price hedonic models by using instrumental variables, spatial statistics, the borders approach, panel data, and other techniques. We introduce a mixed index model to identify house price hedonic regressions.

Two Accounts of Indexicals in Mixed Quotation

Belgian Journal of Linguistics, 2003
When the indexical ‘I’ appears inside quotation marks, it refers not to the person now speaking but to the person whose speech is being reported. The apparently ‘monstrous’ behaviour of quotation can be dismissed in direct speech, so long as one maintains that the quoted part is mentioned rather than used.

Gradient-index profile control from mixed molten salt baths

Applied Optics, 1990
The composition of the molten salt bath was shown to exert a strong influence on the gradient-index profile that resulted from the ion exchange of silver for sodium. Two types of additives were used to enhance the ion exchange from a base AgCl melt. Both techniques reduced the profile degradation that normally occurred with long diffusion times, while ...

A proposed universal homogeneity and mixing index

Powder Technology, 1973
The word “homogeneous” is generally used qualitatively. A simple numerical homogeneity index is proposed suitable for expressing varying degrees of homogeneity quantitatively, namely, the negative log of the sample weight (9) required to obtain a standard deviation of 1%.

A non-sampling mixing index for multicomponent mixtures

Powder Technology, 2017
Abstract Uniform mixing is crucial for different types of molecules, powders, and materials in several chemical, mineral, cement, and drug companies. However, there is no effective index to evaluate the uniformity of mixing of multiple components. This study proposes a non-sampling mixing index (SMI) that is applicable to both multiple mixtures with ...

Modeling Refractive Index In Mixed Component Systems

SPIE Proceedings, 1988
The refractive index of an optical film composed of a mixture of more than one constituent is a function of the micro-structure of the film. Even films that are nominally of a single material have refractive index values that require interpretation on the basis of mixed component models because these values differ significantly from the values in ...

The Index Weighted Hermitian Adjacency Matrices for Mixed Graphs

Utilitas Mathematica
Based on the Hermitian adjacency matrices of second kind introduced by Mohar [1] and weighted adjacency matrices introduced in [2], we define a kind of index weighted Hermitian adjacency matrices of mixed graphs. In this paper we characterize the structure of mixed graphs which are cospectral to their underlying graphs, then we determine a upper bound ...

Policy Mix Coherence Index (PMCI) : A Proposal [PDF]

, 2015
From the policy mix theory to the related empirical works, the quantification of the coordination of monetary and fiscal policies seems to be missing. In this paper, we propose an index (PMCI) which measures the coherent nature of the policy mix rather than it restrictive or expansive character.

HCFA case mix index: implications for hospitals.

Hospital progress, 1981
Since DRGs have stimulated payer interest in per admission, case mix adjusted payment systems, hospitals must begin to anticipate the impact of case mix on payment incentives, data quality, and hospital operations.
