Dimethyl ether (DME) is an alternative energy that simplest ether. DME has 2 ways to synthesis from syngas. The single-step DME synthesis combined methanol synthesis and methanol dehydration in one reactor. This study is focusing on DME production from synthesis gas by used catalyst as...

Carbon dioxide emissions to the atmosphere are drastically increased due to fossil fuel-based power plants and different kinds of industrial processes. Carbon capture is essential to maintain a better environment. Flue gas emissions from the coal-fired power plant, gas-fired power plant, cement...

In this paper we provide a brief overview of some of the most recent empirical research on spatial econometric models and spatial data mining. Data mining in general is the search for hidden patterns that may exist in large databases. Spatial data mining is a process to discover interesting,...

Spatial Filter for spatial autoregressive models like the spatial Durbin Model have seen a great interest in the recent literature. Pace et al. (2011) show that the spatial filtering methods developed by Griffith (2000) have desireable estimation properties for some parameters associated with...
