A feedforward active noise control system includes the secondary path filter for compensation of acoustic coupling between loudspeaker and reference microphone. In ordinary systems, the filter is designed to be a pre-set type, without any system identification for it, because the adaptation of its filter taps without any additional noise is difficult. This paper introduces a new identification ...

Sample path properties of a class of additive functionals of two-dimensional Brownian motion and random walk are studied. AMS 1991 Subject Classification: Primary 60J15; Secondary 60F15, 60J55.

An upper bound is derived on the capacity of a cognitive radio (CR) system by considering the effects of path loss and log-normal shadowing simultaneously for a single-cell network. Assuming that the cognitive radio is informed only of the shadow fading between the secondary (cognitive) transmitter and primary receiver, the capacity is achieved via the water-filling power allocation strategy un...

We investigate secondary view techniques in a multimodal VR environment for dataset exploration and interpretation. Secondary views, such as 3D lenses or mirrors, can present alternative viewpoints, different filtering options, or different data sets. We focus on 3D views showing surface features that are hidden in a main view. We present different view techniques, including new variations, and...

Background: Although powerful, single subunit counting is time consuming, prone to user-bias and largely restricted to Xenopus expression. Results: PIF is an automated analysis program that identifies subunit stoichiometry of any fluorescently-tagged membrane protein from TIRF-recordings. Conclusion: PIF is accurate to more than 90% even in noisy data typical for mammalian expression system. Si...

Mobile ADHOC networks is a wireless network consists of number of nodes. The nodes consists of sending packets from source to destination via path connection. The path connection is of multipath routing and it is very unstable and go down at any time and making the connection on ADHOC network is difficult. If primary path fails to send the packet to destination then the secondary path is used t...
