Statistical measures of unsustainability

Statistical Measures of Distance

Measures of statistical distance are widely used in techniques such as clustering and classification, when we wish to identify objects that are in some sense similar to each other. The choice of distance between data points is an important one, and there are a large number of measures to choose from. In this paper we present some of the most commonly used measures of distance and compare their ...

Unsustainability of Obesity: Metabolic Food Waste

The obesity burden, with 1.5 billion overweight (OW) and 500 million obese (OB) worldwide, significantly increased the risk of degenerative diseases. Excessive consumption of foods that are energy dense lead to obesity, which represents a titanic cost for not only the world's health systems but also a substantial ecological cost to the environment. The waste of resources and the unnecessary gre...

Unsustainability and Overexploitation in Fisheries

The Measure of Unsustainability in Emergy Evaluation

Sustainability is an ideal state, that cannot be “measured” per se. We can instead try to measure the distance from this ideal state. Regarding the use of resources and the emission of residues in the environment, the problem is “extensive”, i.e. a function of the magnitude of the problem (with respect to the size of the system). Humanity is approaching its “limits to growth” and this problem i...

Statistical evaluation of image quality measures

In this work we comprehensively categorize image quality measures, extend measures defined for gray scale images to their multispectral case, and propose novel image quality measures. They are categorized into pixel difference-based, correlation-based, edge-based, spectral-based, context-based and human visual system (HVS)-based measures. Furthermore we compare these measures statistically for ...
