Measuring Linguistic Diversity: A Multi-level Metric

Measuring diversity and level of aggregation

Measuring perceptual contrast in a multi-level framework

In this paper, we propose and discuss some approaches for measuring perceptual contrast in digital images. We start from previous algorithms by implementing different local measures of contrast and a parameterized way to recombine local contrast maps and color channels. We propose the idea of recombining the local contrast maps and the channels using particular measures taken from the image its...

On measuring linguistic intelligence

This work addresses the problem of measuring how many languages a person “effectively” speaks given that some of the languages are close to each other. In other words, to assign a meaningful number to her language portfolio. Intuition says that someone who speaks fluently Spanish and Portuguese is linguistically less proficient compared to someone who speaks fluently Spanish and Chinese since i...

Measuring Linguistic Variation Commensurably

The primary data on pronunciation variation – e.g., dialect atlas data – is often recorded incommensurably, i.e. in different ways in different atlases, and even in different ways within the same atlas when teams of fieldworkers and transcribers are involved. In particular these data collections differ in the detail in which pronunciations are recorded, using between 40 and 100 different basic ...

A Multi-Metric Index for Hydrocarbons Source Apportionment

Several studies have been conducted to develop more accurate and precise indices for hydrocarbons source apportionment. The present study, however, develops a new multi-metric index for hydrocarbons source apportionment. It measures Poly Aromatic Hydrocarbons (PAHs) concentration at six stations with well known petrogenic origin, calculating Phe/An, Flu/Py, Chr/BaA, BaA/Chr, An/(An+Ph), Flu/(Fl...
