In the experiment we proof the paradoxical perception of pitch. A tone sequence demonstrates this paradox: the sequence is perceived as descending, although the first and last tone are identical. The intransitivity of pitch perception generalizes (Shepard 1964). It applies also to harmonic complex tones with variate amplitude envelope and partials that are arranged in intervals different from o...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

Tone mapping algorithms offer sophisticated methods for mapping a real-world luminance range to the luminance range of the output medium but they often cause changes in color appearance. In this work we conduct a series of subjective appearance matching experiments to measure the change in image colorfulness after contrast compression and enhancement. The results indicate that the relation betw...

We implanted microelectrode arrays bilaterally into auditory cortex of trained cats in order to assess dynamic cortical reorganization. Cats were trained to listen to a series of tone-pip pairs and respond to the pair that had di!erent frequencies. Over several months of training, a gradual decrease (!4.2]10~4 Weber Fractions/training day) in the frequency discrimination threshold occurred (p(0...

OBJECTIVE To compare pure-tone audiometry and auditory steady state response (ASSR) to measure hearing loss based on the severity of hearing loss in frequencies. STUDY DESIGN AND SETTING A total of 105 subjects (168 ears, 64 male and 41 female) were enrolled in this study. We determined hearing level by measurement of pure-tone audiometry and ASSR on the same day for each subject. RESULTS P...

Accurately rendering fires is a challenging problem due to the various subtle ways in which the electromagnetic waves interact with this complex participating medium. We present a new method for physically-based rendering of flames from detailed simulations of flame dynamics which accounts for their unique characteristics. Instead of relying on ad-hoc models, we build on fundamental molecular p...

This paper proposes that Northern Tepehuan is a tonal language with just one lexical tone 'low tone' and therefore privative system. L sufficient to explain the pitch contrasts in also necessary "inconsistencies" of stress assignment. Stress normally predictable from size word, syllable-weight, cued by H* intonational tone. Nonetheless, words do not obey Stress-to-Weight constraint, it could be...
