A proposed universal homogeneity and mixing index
Powder Technology, 1973The 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%.

Efficient index updates for mixed update and query loads
2016 IEEE International Conference on Big Data (Big Data), 2016Inverted index files are commonly used to support keyword search in document collections. While the offline construction of an index can be done efficiently, its incremental update remains a hard problem, especially when the index does not completely fit in memory.

A mixed index approach to identifying hedonic price models
Regional Science and Urban Economics, 2006Recent 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.

A Mixed Coding Scheme for Inverted File Index Compression
2006 1st IEEE Workshop on Hot Topics in Web Systems and Technologies, 2006Cluster property of d-gaps in inverted lists provides valuable information for improving index compression and subsequently improving the performance of web search engines. By clustering d-gaps of an inverted list strictly based on a threshold, and then encoding clustered and non-clustered d-gaps using different methods, we can tailor to the specific ...

Mode Mixing With Reduced Losses in Parabolic-Index Fibers
Bell System Technical Journal, 1976We present design criteria for the construction of a modified parabolic-index fiber with intentional mode coupling. Mode coupling serves the purpose of reducing multimode pulse dispersion and is accomplished by introducing carefully designed index fluctuations into the fiber core or by controlled “random” bends of the fiber axis.

The Index Weighted Hermitian Adjacency Matrices for Mixed Graphs
Utilitas MathematicaBased 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 ...
