This study applied input–output analysis to examine the industrial linkage effects of logistics service industry based on data collected from tables provided by World Input–Output Database. The results showed detailed industry, indicating several sectors (transportation, storage, and handling) are not only interdependent but they also form a ecosystem. provide new insights their ripple througho...

In this paper, we develop a new heuristic procedure for the linear ordering problem (LOP). This NP-hard problem has a significant number of applications in practice. The LOP, for example, is equivalent to the so-called triangulation problem for input-output tables in economics. In this paper we concentrate on matrices that arise in the context of this real-world application. The proposed algori...

Physical Supply Use Tables overcome some of the main limitations commonly used Energy Extended Input Output Analysis by describing Conversion Chain in energy terms only. In this paper, we build on recent advances field to construct a Multi-Regional Table framework. We use data from International Agency and have developed open source R packages, thereby enabling easy adoption present work. The n...

abstract aims: one of the consequences of taking ground water into surface is changing its chemical quality, specially increasing the concentration of dissolved salts. this research was performed in order to analyze growth possibility of heterotrophic bacteria in the membrane of active desalination plants in kashan city, iran. instrument & methods: this descriptive cross-sectional study was don...

In this short paper we present an example of the geometric theory of output regulation applied to solve a tracking problem for a plant consisting of a boundary controlled distributed parameter system (heat equation on a rectangle) with unbounded input and output maps and signal to be tracked generated by an infinite dimensional exosystem. The exosystem is neutrally stable but with an infinite (...

We explain the raison d’être and basic ideas of input/output logic, sketching the central elements with pointers to other publications for detailed developments. The motivation comes from the logic of norms. Unconstrained input/output operations are straightforward to define, with relatively simple behaviour, but ignore the subtleties of contraryto-duty norms. To deal with these more sensitivel...
