in this research, we investigated the glottal wave of persian vowels, using electroglottography. in the first level, the properties of vowels glottal wave were analyzed. in the second level, the glottal wave between male and female speakers were  compared. contact quotient is the glottal wave parameter which was analyzed. data included six persian vowels and the glottal wave recorded using elec...

Abstract Motivated by the relevance of so-called nonlinear Froude–Krylov (FK) hydrodynamic effects in accurate dynamical description wave energy converters (WECs) under controlled conditions, and apparent lack a suitable control framework effectively capable optimally harvesting ocean such circumstances, we present, this paper, an integrated to achieve objective, means two main contributions. W...

SG 3524 based modified sine-wave inverter driver circuit, a step-up. Modified sine wave inverter is designed to using pic microcontroller and push pull topology. output of control circuit for modified sine wave inverter The ...

anxiety is one of the most common mental disorders in human societies and is believed that stress and anxiety are responsible for 75% of somatic disease. hence attention to preventive methods to control anxiety and stress and coping strategies need to be considered. therefore, this study aimed at evaluating the effectiveness of mindfulness training on anxiety in students of islamic azad univers...

This document specifies Wave and Equation Based Rate Control (WEBRC), which provides rate and congestion control for data delivery. WEBRC is specifically designed to support protocols using IP multicast. It provides multiple-rate, congestion-controlled delivery to receivers, i.e., different receivers joined to the same session may be receiving packets at different rates depending on the bandwid...

The behaviour of vehicles runing in urban areas depends on the driver behaviour and also, their are influenced by traffic control and environmental factors. On the basis of this context and the increase, year by year, of the number of vehicles in urban areas, the authors are focused on finding solutions to use the current road infrastructure in an intensive manner. The paper presents a new mode...

Abstract. This paper gives a review of research activities at the Institute for Power Electronics and Electrical Drives in Paderborn to the control of rotary travelling wave type ultrasonic motors. Based on a special designed hardware environment an advanced control scheme for inverter-fed travelling wave type ultrasonic motors is presented. After several modelling steps, including an averaged ...
