The present study was conducted to investigate the effectiveness of deductive instruction of grammar with input enhancement and without using input enhancement. It also explored the effectiveness of inductive instruction of grammar with input enhancement and without input enhancement among Iranian EFL learners. The participants were female intermediate-level students who were studying English a...

When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...

The heat pipe applications have been coupled with the renewable energy such as solar energy, waste heat and geothermal energy. Thermosyphon Rankine Cycle (TRC) is a vertical wickless heat pipe engine. In this engine, the turbine is installed between the insulated section and a condenser section of thermosyphon. The mechanical energy developed by the turbine can be converted to electricity, by d...

This paper deals with the performance enhancement for crystallization unit of a sugar plant using genetic algorithm. The crystallization unit of a sugar industry has three main subsystems arranged in series. Considering exponential distribution for the probable failures and repairs, the mathematical formulation of the problem is done using probabilistic approach, and different...

Current dogma is that performance enhancement in sport is wrong. As Pound’s response shows, this dogma is predicated mainly on the view that performance enhancement violates this ‘humanistic’ conception of what sport should be. In this chapter, we will argue that performance enhancement is inevitable and unpoliceable, that it is not against the spirit of sport and that we should remove anti-dop...

the effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. the reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a pc1d simulation....

Image enhancement performance is currently judged subjectively, with no reliable manner of quantifying the results of an enhancement. Current quantitative measures rely on linear algorithms to determine contrast, leaving room for improvement. With the introduction of more complex enhancement algorithms, there is a need for an effective method of quantifying performance to select optimal paramet...
