[1] We present an unmixing method, based on genetic algorithm-soil-vegetationatmosphere-transfer modeling to extract subgrid information of soil and vegetation from remotely sensed soil moisture (downscaled; e.g., soil hydraulic properties, area fractions of soil-vegetation combinations, and unmixed soil moisture time series) that most land surface models use. The unmixing method was evaluated ...

extended abstract introduction the present paper examines the ecological footprint of kermanshah as the 9th largest city of iran. it also tries to answer the following question: dose the ecological environment of kermanshah support the basic needs of it's population? and are the biological systems of kermanshah able to answer all socio- economic questions related to different activities o...

the quality of firms’ reaction against demand uncertainty affects the production inputs employment. in this research i have studied and compared the behavior of active firms in manufacturing sector with respect to the risk attitude and tested it’s effect on production inputs combination(with the special emphasize on labor employment). the research findings reveal that active firms in manufactur...

a central aim of educational research in the area of mathematical modeling and applications is to recognize the attainment level of students at defined states of the modeling process. in this paper, we introduce principles of fuzzy sets theory and possibility theory to describe the process of mathematical modeling in the classroom. the main stages of the modeling process are represented as fuzz...

background this article looks at the long-term, structural determinants of environmental and public health performance in the world system.   methods in multiple standard ordinary least squares (ols) regression models, we tested the effects of 26 standard predictor variables, including the ‘four freedoms’ of goods, capital, labour and services, on the following indicators of sustainable develop...

BACKGROUND Most published attempts to quantify footprint shape are based on a small number of measurements. We applied geometric morphometric methods to study shape variation of the complete footprint outline in a sample of 83 adult women. METHODS The outline of the footprint, including the toes, was represented by a comprehensive set of 85 landmarks and semilandmarks. Shape coordinates were ...

In a process of insect footprint recognition, footprint segments need to be extracted from scanned insect footprints in order to find out appropriate features for classification. In this paper, we use a clustering method in a preprocessing stage for extraction of insect footprint segments. In general, sizes and strides of footprints may be different according to type and size of an insect for r...

The Global Water Footprint Standard approach was used to calculate the volumetric blue and green water footprint indicator for lucerne production as important feed for dairy cows in a major lucerne production region in South Africa. The degree of sustainability of water use then was assessed by comparing water use to water availability for the region. The results show a volumetric water footpri...
