An integral part of intelligent environments is the analysis of the current state of the user in the environment, the socalled context. This can include simple information like the current position but also more specific information like pulse rate or mood. The processing and analysis of this context does allow the implementation of AAL scenarios for user support. They can be applied more speci...

Detection thresholds for biphasic symmetric pulses were measured in fourteen human subjects implanted with the Cochlear Corporation Nucleus 22 Implant. The effects of phase duration on thresholds were studied using single pulses, and 500 ms pulse trains at 100 pps. Psychophysical detection thresholds decreased as a function of phase duration with a change in slope at approximately 0.5 ms/phase....

arterial pulse measurement is one of the most important methods for evaluation of healthy conditions. in traditional iranian medicine (tim), physician may detect radial pulse by holding four fingers on the patient’s wrist. by using this method, under standard condition, the detected pulses are subjective and erroneous, in case of weak and/or abnormal pulses, the ambiguity of diagnosis may rise....

We studied temporal processing of chromatic and luminance perturbations of a 600-nm field, measuring both modulation sensitivity (sinusoidal frequencies from 0.25 to 40 Hz) and pulse-detection thresholds (pulse durations from 5 to 2560 msec) for mean luminances of 0.9 to 900 Td and field sizes of 0.5 degrees to 8 degrees. Chromatic stimuli were produced by antiphase modulation of lights matched...

Tsunami observations play an important role in resolving offshore earthquake slip distributions. Non-dispersive models are often used with an initial static sea-surface pulse derived from seafloor deformation in computation of tsunami Green's functions. We compare this conventional approach with more advanced techniques, which use Green's functions computed by a dispersive model with an initial...

near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. these pulse-type ground motions can be represented by pulse sequences with simple shapes. half-sinusoidal pulse sequences are used to approximate recorded ground motions and dynamic responses of sdof system under the excitation of these pulse sequences are studied. four cases are consi...

In many practical situations, however, the environment is presence of strong pulse jamming (PJ) with high intensity; the pulse jamming is with binomial distribution. In this case, the pulse jamming can cause drastic degradation in the performance of Constant False Alarm Rate (CFAR) processors. In this paper, CA CFAR and CA CFAR BI (binary integration) processors in binomial distributed pulse ja...

The effects of pulse rate on absolute threshold ~THS!, maximum acceptable loudness ~MAL!, and dynamic range ~DR! were evaluated in 15 Clarion cochlear implant users. A wider range of pulse rates was assessed than in previous studies, and subjects with both standard and perimodiolar electrode arrays were tested. THS and MAL decreased with pulse rate, and DR increased with pulse rate, for pulse r...
