As the penetration of renewable energy sources (RES) into energy market is becoming increasingly evident, it is urgent to deal with the problem of fluctuations of RES. Compressed Air Energy Storage (CAES), as one of energy storage technologies aiming at this problem, has excellent...

A (2+1)-dimensional Bossinesq–Burgers soliton equation is proposed, which has a affinitive connection with the Boussinesq–Burgers soliton hierarchy. Through a natural nonlinearization of the Boussinesq–Burgers's eigenvalue problems, a finite-dimensional Hamiltonian system is obtained and...

This article empirically investigates the impact of GPR (geopolitical risk) and its subdivided indices on the volatility of energy prices and whether they have predictive power for the volatility of energy futures prices. The single factor, double factor GJR-GARCH-MIDAS models, are applied for...

Based on the study of the confocal Lax matrix, new confocal involutive systems and a new spectral problem are proposed from which a hierarchy of generalized coupled KdV equations is derived. The Abel–Jacobi coordinates are introduced to straighten out the associated flows. Algebro-geometric...

Laboratory studies have provided evidences regarding the impacts of engine technology on vehicle emissions; however, questions remain regarding the relations between alternative vehicle fuels and on-road vehicle emissions as well as energy demands from upstream fuel production processes to...

Heat waves have taken place more and more frequently in Beijing due to the rapid urban expansion since the mid-1970s, which has been greatly affecting people’s life and social production. The aim of this paper was to provide a novel process which can be employed to accurately forecast the heat...

A simulation model consisting of wind speed, wind turbine and AA-CAES (advanced adiabatic compressed air energy storage) system is developed in this paper, and thermodynamic analysis on energy conversion and transfer in hybrid system is carried out. The impacts of stable wind speed and unstable...

Purpose – The purpose of this paper is to claim that it is useful to assess the web connectivity of research groups, describe hyperlink‐based techniques to achieve this and present brief details of European life sciences research groups as a case study. Design/methodology/approach – A...

The use of the Web by academic researchers is discipline‐dependent and highly variable. It is increasingly central for sharing information, disseminating results and publicising research projects. This pilot study seeks to identify the subjects that have the most impact on the Web, and look...

Since 1996, hyperlinks have been studied extensively by applying existing bibliometric methods. The Web impact factor (WIF), for example, is the online counterpart of the journal impact factor. This paper reviews how this link‐based metric has been developed, enhanced and applied. Not only has...
