Although k-means clustering is often applied to time series clustering, the underlying Euclidean distance measure is very restrictive in comparison to the human perception of time series. A time series and its translated copy appear dissimilar under the Euclidean distance (because the comparison is made pointwise), whereas a human would perceive both series as similar. As the human perception i...

Vibration threshold determinations were made by means of an electromagnetic vibrator at three sites (carpal, tibial, and tarsal), which were primarily selected for examining patients with polyneuropathy. Because of the vast variation demonstrated for both vibrator output and tissue damping, the thresholds were expressed in terms of amplitude of stimulator movement measured by means of an accele...

Little is known about whether and how multimodal representations of the body (BRs) and of the space around the body (Peripersonal Space, PPS) adapt to amputation and prosthesis implantation. In order to investigate this issue, we tested BR in a group of upper limb amputees by means of a tactile distance perception task and PPS by means of an audio-tactile interaction task. Subjects performed th...

background: examining the quality of nursing care from the patient's perspective is an important element in quality evaluation. the extent to which patients' expectations are met will influence their perceptions and their satisfaction with the quality of care received. methods:   a cross- sectional survey was conducted among admitted patients at king khalid teaching hospital, riyadh, saudi arab...

This paper describes a logical approach to embodied perception and reasoning in the context of Cognitive Robotics that use feature clouds to encode an explicit 3D description of bodies of arbitrary structural complexity. We extend and apply the principles of abductive perception in order to provide robots with an explicit, flexible, and scalable three-dimensional representation of the world for...

Our subjective experience of the world is ‘unitary coherent’ (UC). ‘Unitary’ means we only perceive one interpretation at a time rather than a blur of multiple possible worlds. ‘Coherent’ means that we almost always perceive scenes that do not contain contradictory parts. While this form of first-person perceptual experience may seem obvious, it is in opposition to the requirements of optimal d...

This preliminary study aims at investigating the production and perception of the English nasals /m/ and /n/ in word-final position by a group of 10 intermediate Brazilian EFL learners. Production data was collected by means of a Sentence Reading Test considering preceding vowel as phonological context. Perception was assessed by means of an identification test contrasting native-like vs. nonna...

The so-called regression effect is often observed in the rhythm perception and production domain: a sequence of durations is perceived as more contrasted then they are performed, while the same rhythms are produced as less contrasted. The current study offers a possible explanation to this effect by relating perception and production of simple rhythmic patterns using a Bayesian framework. Thirt...
