<section xml:id="fut21653-sec-0001"> We develop the Nelson–Siegel model in the context of option‐implied volatility term structure and study the time series of volatility components. Three components, corresponding to the level, slope, and curvature of the volatility term structure, can be interpreted as the long‐,...</section>

This study presents the auxiliary damping control with the reactive power loop on the rotor-side converter of doubly-fed induction generator (DFIG)-based wind farms to depress the sub-synchronous resonance oscillations in nearby turbogenerators. These generators are connected to a series...

We examined the effect of different irrigation and nitrogen (N) fertilizer levels on Zea mays L. (maize) on nitrate-nitrogen (NO3−-N) leaching under lysimeter conditions. To do so, we used large lysimeters (2.5m×2.5m×2.0m deep) at the Maize Technological Innovation Center (MTIC) of the...

We develop the Nelson-Siegel model in the context of option-implied volatility term structure and study the time-series of three volatility components in the model. We show that these components, corresponding to the level, slope and curvature of the volatility term structure, can be interpreted...

Entropy generation rate is directly related to exergy destruction and is therefore to useful energy. This study investigates temperature distribution and local and total entropy generation rates within a composite hollow cylinder with temperature-dependent thermal conductivity and internal heat...

Precise prediction of thermal processes is one of the major concerns in the field of heat transfer and within energy research communities. It has been proven that using LTE (local thermal equilibrium) conditions within a porous medium may give researchers erroneous data. From another point of...

Data on 26,857 Japanese foreign investments in 150 countries and regions over the 1991-1999 period reveal that there are stark differences in the characteristics and performance of Japanese FDI (JFDI) between less developed countries (LDCs) and developed countries (DCs). JFDI in LDCs has been...

This article investigates the classical entropy generation in cooled slabs. Two types of materials are assumed for the slab: homogeneous material and FGM (functionally graded material). For the homogeneous material, the thermal conductivity is assumed to be a linear function of temperature,...
