Building Qualitative Models of Thermodynamic Processes
نویسندگان
چکیده
This paper describes a qualitative domain theory for core phenomena in engineering thermodynamics, expressed in Qualitative Process theory . It represents many of the best features of domain models developed by our group over the past five years . It focuses on supporting system-level qualitative analyses of typical fluid and thermal systems, such as refrigerators and power plants . We use explicit modeling assumptions [3] to control the level of detail used in building models of specific scenarios. We begin by outlining the primitives of the specific QP modeling language . The bulk of the paper describes the domain model itself, highlighting our design choices, simplifications, and use of modeling assumptions . Next we demonstrate how this domain model can be used to build models of a variety of specific scenarios, including simplified versions of a refrigerator, a steam plant, and a thermal control system . Finally, we describe some planned extensions to the model .

Control chart based on residues: Is a good methodology to detect outliers?
The purpose of this article is to evaluate the application of forecasting models along with the use of residual control charts to assess production processes whose samples have autocorrelation characteristics. The main objective is to determine the efficiency of control charts for individual observations (CCIO) and exponentially weighted moving average (EWMA) charts when they are applied to res...

The Generalized Maxwell-Stefan Model Coupled with Vacancy Solution Theory of Adsorption for Diffusion in Zeolites
It seems using the Maxwell-Stefan (M-S) diffusion model in combination with the vacancy solution theory (VST) and the single-component adsorption data provides a superior, qualitative, and quantitative prediction of diffusion in zeolites. In the M-S formulation, thermodynamic factor (Г) is an essential parameter which must be estimated by an adsorption isotherm. Researchers usually utilize the ...
