Two-fluid model and hydrodynamic constitutive relations Two-fluid formulation for two-phase flow analyses is presented. A fully three-dimensional model is obtained from the time averaging, whereas the one-dimensional model is developed from the area averaging. The constitutive equations for the interfacial terms are the weakest link in a two-fluid model because of considerable difficulties in terms of experimentation and modeling. However, these are of supreme importance in determining phase interactions. In view of this, the interfacial transfer terms have been studied … Continue reading “Latest Research on Fluid Engineering : Dec 2020”

  Transforming the energy sector: the evolution of technological systems in renewable energy technology This paper analyses the development and diffusion of technologies that utilize renewable energy sources in Germany, Sweden and the Netherlands. The analysis enlarges the life cycle model of industry evolution to one where the focus is on the formation and evolution of new technological systems. Particular focus is on explaining success and failures in shifting from a formative phase into one characterized by positive feedbacks. A … Continue reading “Latest Research on Energy Technology : Dec 2020”

Engineering support vector machine kernels that recognize translation initiation sites Motivation: In order to extract protein sequences from nucleotide sequences, it is an important step to recognize points at which regions start that code for proteins. These points are called translation initiation sites (TIS). Results: The task of finding TIS can be modeled as a classification problem. We demonstrate the applicability of support vector machines for this task, and show how to incorporate prior biological knowledge by engineering an appropriate … Continue reading “Latest Research on Machine Engineering : Nov 2020”
