background: consumption of energy drinks has become widespread among athletes. the effectiveness of red bull and hype energy drinks on selected indices of maximal cardiorespiratory fitness and blood lactate levels in male athletes was examined in this study. methods: ten male student athletes (age: 22.4 ± 2.1 years, height: 180.8 ± 7.7 cm, weight: 74.2 ± 8.5 kg) performed three randomized maxim...

This paper deals a production and maintenance optimization problem for a wind turbine system in order to satisfy a random demand under given service level. A jointly optimization is made by combining between energy production and maintenance plan in order to establish an economical energy production planning and an optimal maintenance strategy according to the wind turbine degradation. The key ...

Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses.
