About The Book Elements Of Electrical Power Station Design Book Summary:This comprehensive textbook is primarily aimed at undergraduate engineering students of Electrical Engineering, both at degree and diploma level.The book covers preliminary designs and economic loading of diesel-electric stations, steam stations, nuclear power stations and hydro-electric stations. It discusses load forecasting, economic load dispatch, unit commitment problem, methods of scheduling stations, allocation control, system reliability and system security. Trends in power plant instrumentation and control are also presented. The important problems of pollution control and performance standards of thermal power stations are discussed. The application of computers in power systems is touched.The book also explains the need of using unconventional sources of energy and plants, like biogas plants, biomass plants, solar electric system and wind electric system to save fossil fuels. Rural energy demands and methods of forecasting energy demands are elaborated.

Our results showed that in all LSOT conditions MV increased the amount of sway variability during walking. In addition, the effect of MV was more pronounced in LSOT condition 2 and 5, both of which are associated with reduced vision. In our previous study, healthy young adults showed no significant increase in sway when standing with eyes closed in comparison to standing with eyes open6. However, the amount of sway variability during reduced and perturbed vision walking was significantly larger in comparison to normal walking7. Thus, the role of vision in standing postural control is not same as in locomotor postural control7,16,17. In healthy adults, vision plays crucial role to modulate the gait cycle, navigate the direction and avoid the obstacles16; however, for standing, the role of vision for keeping balance can be altered by other sensory systems16. Moreover, for patients with Acquired brain injury, better balance during standing is found with eye-closed in comparison with eye-opened17. However, these patients could not keep balance with eye-closed during walking17. Surprisingly, bilateral MV had a larger effect than unilateral MV only in LSOT conditions 2 (reduced vision) and 6 (vision and somatosensory are both manipulated). This is contrary to our findings in young adults14, for whom significantly larger effects were observed on application of MV in all LSOT conditions that involved sensory manipulations (i.e. all but Condition 1). We suspect that this result may be an effect of statistical power. From observation, there existed a trend such that bilateral MV affected the amount of sway variability in conditions where any sensory system was perturbed. Our results showed the power of MV and condition effect around 0.9 for the amount and temporal structure variability, but for sway area was around 0.9 for condition effect and 0.45 for MV effect. We believed we had decent power in this current study but might not exceed the level of significance of this particular situation. Of note, the amount of sway variability was considerably higher in this group, occasionally even doubling the values observed in our young adult population14, indicating that the older adults were much more challenged by our overall experimental design. These large increases in variability reflect a significant positional drift towards the front and the back of the treadmill; as sensory input is affected, positional information during locomotion is compromised. These results lead us to believe that MV, due to the affected vestibular input, causes confusion of the egocentric body-centered coordination system used during walking18,19. The larger increases in the amount of sway variability induced by MV in older adults may be due to a greater confusion of the egocentric body-centered coordinate system than that experienced by young adults14. This hypothesis is supported by Deshpande and Patla (2007) who demonstrated that vestibular input reweighting is less effective in older individuals in challenged walking than in young adults4. 2ff7e9595c
