Rough set theory is a paradigm for approximate reasoning based on the assumption that concepts are divided into exact and non–exact (called also rough) ones by means of a topological structure induced by a representation of knowledge as a classification. A classification in its most simple form is an equivalence relation on a universe of objects; the classification induces a partition topology ...

Inability to recognize emotional expressions of others (emotion perception) is one of the most common impairments observed among individuals with schizophrenia. Such deficits presumably contribute much to the social dysfunction characteristic of schizophrenia. This study examined the efficacy of a novel attentional-shaping intervention to improve emotion perception abilities. Sixty participants...

The aim of this report is threefold: (1) First, we accomplish a survey integrating the description of consciousness, perception, and memory according to the views of descriptions of Hermann Helmholtz, Sigmund Freud, Henri Bergson, and Gustav Jung. (2) In the second step, we present experimental results for defining the machineries of sensation and perception: (a) electrical responses of isolate...

The human visual system has a remarkable ability to interpret smooth patterns of light on a surface in terms of 3-D surface geometry. Classical studies of shape-from-shading perception have assumed that surface irradiance varies with the angle between the local surface normal and a collimated light source. This model holds, for example, on a sunny day. One common situation in which this model f...

Reducing salt (NaCl) intake is an important public health target. The food industry and catering services are searching for means to reduce the salt content in their products. This review focuses on options for salt reduction in foods and the sensory evaluation of salt-reduced foods. Simple salt reduction, mineral salts and flavor enhancers/modifiers (e.g., umami compounds) are common options f...

In this paper, we propose to evaluate the quality of emotional speech synthesis by means of an automatic emotion identification system. We test this approach using five different parametric speech synthesis systems, ranging from plain non-emotional synthesis to full re-synthesis of pre-recorded speech. We compare the results achieved with the automatic system to those of human perception tests....

BACKGROUND Some asthmatic patients perceive the severity of their disease rather poorly. These patients may not receive optimal therapy because of underpresentation of their respiratory symptoms. It is therefore important to identify these patients. The present study evaluates a new threshold loading device for measuring the perception of respiratory sensation. This method for measuring the per...

We report on preliminary work in the application of lowlevel visual motion cues to identify potential hazards during on-road driving. In conjunction with a clinical study of hazard perception in older age drivers, we consider the detection of a range of hazardous scenarios identified as particularly challenging for older drivers in video sequences used in the clinical study. Central to our appr...
