This paper provides a comparative analysis of five possible production strategies for two kinds of flexibility investment, namely flexible technology and flexible capacity, under demand fluctuations. Each strategy is underpinned by a set of operations decisions on technology level, capacity...

The Nambu spinor Green’s function approach is applied to studying the proximity effect in ferromagnet/d-wave superconductor (FM/d-wave SC) junctions. It is found that the magnitude of the proximity effect depends to a great extent on the orientation of the SC crystal with respect to the...

This study investigates the performance of hybrid renewable microgeneration systems in load sharing application between a detached residential house and a small office building. Two renewable energy systems are investigated: a ground source heat pump (GSHP) system and a hybrid GSHP/fuel cell...

This study investigates the application of Adaptive Neuro-Fuzzy Inference System (ANFIS) technique to predict the performance of a hybrid microgeneration system. The hybrid system consists of an internal combustion engine (1kWe and 3.2kWth) integrated with a high efficiency condensing furnace...

Time series often contain unknown trend functions and unobservable error terms. As is known, Yule–Walker estimators are asymptotically efficient for autoregressive time series. The focus of this article is the Yule–Walker estimators for time series with trends. A nonparametric detrending...
