Investigating speech tempo, speaking rate, and the related factors in the iranian elderly women talking with tehrani and semnani accents
No full textBackground: Some variables, such as age, gender, regional and dialectical differences influence speech tempo. Men and younger individuals speak faster than women and the elderly. Therefore, these variations should be considered when assessing speaking rate. Objectives: Since different accents influence speaking rates and there is no previous study investigated speech tempo with respect to regional and accent differences in Iran, and given that the elderly are more prone to problems influencing speaking rate, the present study was done to compare speech tempo and speaking rate in two different accents, namely Tehrani and Semnani, and to investigate some related factors. Methods: This cross-sectional study was performed on 200 elderly women selected via convenience sampling method. Speech tempo, speaking rate, verbal fluency, and cognition scores were compared using an independent-samples t-test. Pearson�s correlation coefficient test was used to assess correlations between speaking rate and level of education, Montreal cognitive assessment (MoCA), and verbal fluency scores. Results: No significant difference was found in speech tempo between the studied accents (P = 0.13). Speaking rate was significantly slower in the Tehrani accent than the Semnani one (P = 0.04). The Tehrani elderly obtained significantly less scores in verbal fluency and MoCA ((P � 0.001) and (P = 0.04), respectively. In both groups, speaking rate had a significant correlation with verbal fluency and MoCA scores but not with level of education. Conclusions: Although, our results showed no difference in speech tempo between the studied accents, the Tehrani elderly unexpectedly spoke more slowly meaning that they paused more while speaking. There was a relationship between faster speaking, better verbal fluency, and cognitive performance. © 2021, Author(s)
Energy harvesting from train vibrations
No full textIn this paper, linear mechanical oscillators are designed to harvest energy from train-induced vibrations. The harvested energy could be used, for example, to charge sensors mounted on the rail track for structural health monitoring. The dominant frequencies due to a passing train are determined for a specific train and speed from a recorded acceleration time-history. Using a simple model of an oscillator, the total energy harvested for the passage of one train is calculated. The stiffness, and hence the tuning frequency of the device, is varied in simulations to determine the optimum frequency at which to tune the device for a constant value of mass and damping in the device. Further simulations are conducted to investigate the power that could be harvested from multiple oscillators tuned at several dominant frequencies, and their performances are analysed and compared. The constraint for maximum relative displacement is considered in the design of each harvester, and this is adopted to assure that the amplitude of the oscillation is finite and does not exceed the physical size of the device. The robustness of the harvester is also analysed for different train speeds
Energy harvesting using semi-active nonlinear control
No full textThis paper presents the application of semi-active control for power harvesting using an electromechanical energy harvester. Two semi-active control strategies are proposed in the form of a time-periodic damper and a nonlinear cubic damper. For the periodic time-varying damper the average harvested power and the throw are obtained based on the Fourier series. The semi-active periodic time-varying damper is optimised to maximise the harvested power. The performance of the optimum semi-active periodic damper is compared with the optimum passive and semi-active on-off model at a particular frequency. It is demonstrated that the periodic time-varying damper can significantly increase the harvested power at all frequencies of interest. For the nonlinear damper, the harvested power and the throw are derived using the concept of the describing function. The results are compared with the linear damper. It is demonstrated that the nonlinear damper can significantly increase the absorbed power despite having much lower displacement compared to the linear damper. This makes the semi-active nonlinear damper very attractive for mechanical energy harvesters
