In this paper, we present a novel model-agnostic machine learning technique to extract reduced thermochemical model for reacting hypersonic flows simulation. A first simulation gathers all relevant thermodynamic states and the corresponding gas properties via given model. The are embedded in low-dimensional space clustered identify regions with different levels of (non)-equilibrium. Then, surro...

The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...

The production and subsequent processing, packaging and distribution of food cannot be considered in isolation from the rest of the country's economy. The Input-Output Tables for the United Kingdom (Central Statistical Office, 1968) illustrate the complex interdependencies of all its industries and may indeed be used to quantify the importance of other industrial inputs in determining the outpu...

Preparation of regional input-output tables requires statistical methods combined with high costs and too much time. Obtained estimates by non-statistical methods have low confidence coefficient. Therefore, integrated methods for this purpose are suggested by recent input – output studies. In this study, first GRIT method is introduced as an appropriate integrated method for preparation of inpu...
