An algorithm for labeling a two-speaker phone call according to the active speaker at each time frame is presented. The algorithm is based on clustering audio frames according to one features set, and then modeling speakers for each cluster and resegmenting iteratively, over a different features set. The first clustering stage is expected to yield clusters that contain audio of both speakers gr...

Background: The development of active gaming offers a choice for children to be physically active whilst participating in an activity that is enjoyable and highly valued. Children expend energy when they play activity enhanced video games, yet little is known about their choice when given active alternatives over seated play. Methods: This study examined (i) choice of play between a seated vide...

Vibration suppression of rotating machinery is an important engineering problem. In this paper, a review of the research work performed in real-time active balancing and active vibration control for rotating machinery, as well as the research work on dynamic modeling and analysis techniques of rotor systems, is presented. The basic methodology and a brief assessment of major difficulties and fu...

A set of tools that is being developed for the automated inspection of rubble-mound breakwaters, as well as its application to the survey of Sines' west breakwater armour layer, are described. The results from the IRIS surveys are compared to those of the surveys carried out by the Portuguese Hydrographic Institute and first assessment of the structure evolution between 2000 and 2003 is made.

The adoption of hybrid-electric aircraft is expected to have a considerable impact on airport operations, with the need new infrastructural requirements support electric-powered fleets. In particular, battery-charging shall play decisive role. Preliminary investigations useful perform scenario studies for future implementation aviation can take advantage ARES methodology presented here, which p...

in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

A mechanical support in a longwall complex requires proper supervision and control of operating parameters because it is responsible for the safety machines workers. Its main functions are to protect excavation against adverse effects rock mass move along with operational progress shearer scraper conveyor. In era Industry 4.0 as well green economy sustainable development, development devices in...
