Preliminary Test Of A Real-Time, Interactive Silent Speech Interface Based On Electromagnetic Articulograph, Jun Wang, Ashok Samal, Jordan R. Green
CSE Conference and Workshop Papers
A silent speech interface (SSI) maps articulatory movement data to speech output. Although still in experimental stages, silent speech interfaces hold significant potential for facilitating oral communication in persons after laryngectomy or with other severe voice impairments. Despite the recent efforts on silent speech recognition algorithm development using offline data analysis, online test of SSIs have rarely been conducted. In this paper, we present a preliminary, online test of a real-time, interactive SSI based on electromagnetic motion tracking. The SSI played back synthesized speech sounds in response to the user’s tongue and lip movements. Three English talkers participated in ...

The Application Of Boundary Layer Climatology And Urban Wind Power Potential In Smarter Electricity Networks, Keith Sunderland, Gerald Mills
Smart electricity networks that address energy demand, efficiency and sustainability concerns are predicated on the ability to capture renewable energy in a controllable manner. Such networks will have a particular role in cities, where increasing demand is inevitable but this requires that primary (renewable) energy resources, including that of wind, is better understood. In this paper, the role of wind energy systems, as integral components of a smarter urban electricity network, is considered using a model of the urban wind resourcein Dublin, Ireland that is based on boundary layer theory and meteorological observations.

Fault Locating In Large Distribution Systems By Empirical Mode Decomposition And Core Vector Regression, Benyamin Khorramdel Mr., Hesamoddin Marzooghi Mr., Haidar Samet Dr., Meisam Pourahmadi-Nakhli Mr., Mahdi Raoofat Dr.
This paper proposes an intelligent fault locating method using a new signal analysis technique called Empirical Mode Decomposition (EMD) and Core Vector Regression (CVR) for large distribution systems. The conventional fault locators are based on the measurement of post-fault line impedance suffering from the factors such as path fault impedance, system configuration and line loading, so that they have low accuracy. On the other hand, because of the vast range of resistances, the negative impact of damping factors affects the performance of travelling wave-based fault locators in large distribution systems. To overcome these problems, this paper uses a minimum measuring ...

Master's Theses and Project Reports
High-Speed Mobile Networks for Modern Farming and Agricultural Systems
High-speed mobile networks are necessary for agriculture to inventory individual plant health, maximize yield and minimize the resources applied. More specifically, real-time information on individual plant status is critical to decisions regarding the management of resources reserved and expended. This necessity can be met by the availability of environmental sensors (such as humidity, temperature, and pH) whose data is kept on storage servers connected to static and mobile local area networks. These static and mobile local area networks are connected to cellular, core and satellite networks. For ...
