The design and optimization of ground source heat pump systems require the ability to accurately reproduce the dynamic thermal behavior of the system on a short-term basis, specially in a system control perspective. In this context, modeling borehole heat exchangers (BHEs) is one of the most...

Generalized Method of Moments (GMM) estimation is discussed under the joint occurrence of fixed effects and random measurement errors in an autoregressive panel data model. Finite memory of measurement errors is allowed for. Two GMM specializations are considered: (i) using instruments (IVs) in...

Pundits, politicians, and political scientists alike often bemoan the long delays in filling both executive and judicial vacancies. However, most political science scholarship has ignored why executives delay nomination, instead focusing on why legislatures delay confirmation. In this article, I...

O MIMES – Multi-scale Integrated Model of the Earth Sytems Ecological Services é o primeiro modelo global a relacionar a dinâmica entre a tecnologia, produção e bem-estar econômico e os bens e serviços ecossistêmicos do sistema dinâmico da Terra, de forma espacializada. É um...

The Shell coal gasification system is a single-stage, up-flow, oxygen-blown gasifier which utilizes dry pulverized coal with an entrained flow mechanism. Moreover, it has a membrane wall structure and operates in the slagging mode. This work provides a detailed dynamic model of the 300MW Shell...

This paper presents a dynamic simulation model to predict the performance of an ASHPWH (air source heat pump water heater). The developed model is used to assess its performance in the Lebanese context. It is shown that for the four Lebanese climatic zones, the expected monthly values of the...
