In this paper, dynamic modelling of gas turbines is analysed in two aspects, or two dimensions. First, support of the life cycle of the engine and its control system represents a time domain perspective. Second, the concept of unified information space is introduced in order to reflect the interaction of various forms of mathematical models in the “space” dimension. Modern information technolog...

Natural Language Generation (NLG) can be used to generate textual summaries of numeric data sets. In this paper we develop an architecture for generating short (a few sentences) summaries of large (100KB or more) time-series data sets. The architecture integrates pattern recognition, pattern abstraction, selection of the most significant patterns, microplanning (especially aggregation), and rea...

Development of micromachine gas turbines is underway at a group lead by Tohoku University in Japan. The goal is to develop a light-weight power source to replace the heavy batteries that may limit the progress of humanoid robots. Internal combustion engines have advantages of both high power density and high energy density, so it can be the best choice for the power source for mobile machines. ...

Published data imply an average thermal efficiency of about 0.34 for U.S. electricity generating plants. With clever use of thermodynamics and technology, modern gas and steam turbines can be coupled, to effect dramatic efficiency increases. These combined-cycle power plants now reach thermal efficiencies in excess of 0.60. It is shown how the laws of thermodynamics make this possible. VC 2012 ...

Distributed Generation (DG) is expected to play a key role in the residential, commercial and industrial sectors of the power system. Distributed Generation (DG) provides an alternative to the traditional electricity sources i.e. oil, gas, coal, water etc. and can also be used to enhance the current electrical system. The technologies for DG are based on reciprocating engines, photovoltaic, fue...
