In modern gas turbine the temperature of the exhaust gases is in the range of 500 o C to 550 o C. Modern steam power plants have steam temperature in the range of 500 o C to 630 o C. Hence gas turbine exhaust can be utilized by a waste-heat recovery boiler to run a steam turbine based on Rankine cycle. The efficiency of a gas turbine which ranges from 28% to 33% can be raised to about 60% by recovering some of the low grade thermal energy from the exhaust gas for steam turbine process. This paper is a study for the modelling of gas turbine and using this model for optimizing the power of CCGT by varying parameters. The performance model for CCGT plant was developed in MATLAB/Simulink.

However, the recent advances in neurophysiological tools allowed useful human behavioral constructs to be measured in real-time, such as human emotion, perception, preferences and task performance. Electroencephalography (EEG), and functional near-infrared spectroscopy (fNIRS) are well received neuroimaging tools and they are being used in variety of different domains such as health science, neuromarketing, user experience (UX) research and multimedia quality of experience (QoE) discipline. Therefore, this paper describes the impact of natural and text-to-speech (TTS) signals on a user's affective state (valence and arousal) and their preferences using neuroimaging tools (EEG and fNIRS) and subjective user study. The EEG results showed that the natural and high quality TTS speech generate “positive valence”, that was inferred from a higher EEG asymmetric activation at frontal head region. fNIRS results showed the increased activation at Orbito-Frontal Cortex (OFC) region during decision making in favor of natural and high quality TTS speech signals. But natural and TTS signals have significantly different arousal levels.
