conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

Face appearance in support of biometric recognition has been conventional with researcher for many years. Face systems have successfully made the changeover from the research laboratory to the commercial zone. Biometric detection should make use of dimensions that are solely subject-intrinsic, avoiding integration of other contaminate inputs and the property of imaging system revolution as much...

turbocharging an engine boosts its power by increasing the amount of input air. this task is accomplished by using the exhaust gas to power a turbine which is engaged with a compressor. the variable geometry turbocharger, vgt is a unique turbocharger that the diffuser vane angle can be changed over a wide range of positions. the mathematics of turbomachinery flow analysis is intensive and uses ...

Multifrequency composites seems to be a good approach to increase the acoustic bandwidth of standard piezoelectric composites. The mechanical coupling between the different piezoceramic elements introduces new degrees of freedom into their design. Monodimensional models have been developed to study their performances in a first approximation. In order to obtain a powerful design model, a two-di...

End-to-end quality of service for real-time video delivery over ATM networks depends on both video coding and network performance. Historical measures of QoS for data services have involved packet delivery parameters such as cell loss and delay, but these are not directly representative of a user's perception of the delivered video quality. To this end, this paper describes the use of a video q...
