This paper presents a time domain analysis framework for predicting nonlinear response of long-span bridges under turbulent winds. The nonlinear unsteady aerodynamic forces are modeled based on static force coefficients, flutter derivatives, admittance functions, and their spanwise correlations at varying angles of incidence. This analysis framework incorporates frequency dependent parameters o...

This six-year project started with the idea of applying sound recognition and separation techniques that had originated in speech recognition to a broader domain of environmental sound mixtures. As it proceeded, the work diversified into several distinct areas, reflecting the different directions of the graduate students primarily supported by the project: Manuel Reyes and Keansub Lee worked on...

The rapid development of speech synthesis technology has significantly improved the naturalness and human-likeness synthetic speech. As technical barriers for are rapidly lowering, number illegal activities such as fraud extortion is increasing, posing a significant threat to authentication systems, automatic speaker verification. This paper proposes an end-to-end detection model based on audio...

objectives: the aim of this study was to translate the craig hospital inventory of environmental factors (chief) into persian language and to evaluate the validity and reliability of persian version of chief to use for children with cerebral palsy. methods: the chief was translated from english into persian based on the international quality of life assessment (iqola) approach. the persian vers...

today many of wide scope and famous organizations design and develop hse models to achieve a more suitable hse management system for their own purposes. to implement such models some requirements should be considered in line with defined goals and missions. the present study was carried out in order to achieve the hse management system for children and adolescents in education and training cent...

tourism has traditionally been implemented by means of different motivators. tourism began in 1330 and the ecotourism is the main reason for the development of personality and promotion of cultures. circulating in the nature is a course of thinking for scientists in islam. ecotourism is a branch of tourism and it enters the world of its literature in 1970. ecotourism has been doubled in compari...

The variability of the north Australian wet season is examined by performing cluster analysis on the wind and thermodynamic information contained in the 2300 UTC radiosonde data at Darwin for 49 wet seasons (September–April) from 1957/58 to 2005/06. Five objectively derived regimes of the wet season are obtained and are found to differ significantly in their synoptic environment, cloud patterns...

The use of stochastic modeling is discussed for analysis/synthesis and transformation of environmental sounds. The method leads to perceptually relevant synthetic sounds based on the analysis of natural sounds. Applications are presented, such as sound effects using parametric signal transformations, or data compression. Moreover, we propose a method which efficiently combines the stochastic mo...
