Energy consumption in the residential sector is a complex socio-technical problem that can be explained using acombination of physical, demographic and behavioural characteristics of a house and its occupants. In this paper, byusing the energy consumption data for the residential sector of Shiraz in Iran, the effect of built area (BA) andoccupant number (Occ) on annual energy consumption (Ec) w...

chapter two presents three m-admissible function algebras ab, bd, and sl, to construct the universal abelian, band, and semilattice compactifications, respectively. the main results are (11.3), (12.3), and (12.4). some inclusion relationships between these function algebras and the other well-known ones, presented in section 8, are made via the devico of compactifications. chpter three is about...

Due to the more dependence among countries and the raised demand for energy, the energy trade have increased during recent decades, while its major share is intra-industry trade (IIT). In this regard, countries are trying to exploit the diversity of a particular product, as well as the technology transfer and knowledge of technology which generated by IIT in this sector. According to the import...

This paper tries to demonstrate the importance of non-economic exogenous factors (Underlying Energy Demand Trend) when we estimate the industrial energy demand for Iran. The Structural Time Series Model (STSM) approach is used to model these unobservable factors. The Kalman filter and Maximum Likelihood methods allow us to estimate the value of the UEDT. This approach enables us to obtain more ...
