Motivation: Much of human social behavior is influenced by the directional, foveated nature of our visual perception. We have developed characteristic eye and head movements to serve the functional requirements of acquiring information through vision, and we intuitively “read” those movements in others. A humanoid robot whose vision system follows the human organization can enter into this impl...

This study addresses the interrelations between human wayfinding performance, the mental representation of routes, and the geometrical layout of path intersections. The virtual reality based empirical experiment consisted of a route learning and reproduction task and two choice reaction tasks measuring the acquired knowledge of route decision points. In order to relate the recorded behavioural ...

The extent to which human speech perception evolved by taking advantage of predispositions and pre-existing features of vertebrate auditory and cognitive systems remains a central question in the evolution of speech. This paper reviews asymmetries in vowel perception, speaker voice recognition, and speaker normalization in non-human animals - topics that have not been thoroughly discussed in re...

The goal of this paper is to provide an overview of an emerging new framework for understanding early phonetic development – The Natural Referent Vowel (NRV) framework. The initial support for this framework was the finding that directional asymmetries occur often in infant vowel discrimination. The asymmetries point to an underlying perceptual bias favoring vowels that fall closer to the perip...

high temperatures are often encountered in almost all of the combustion systems, therefore, thermal radiation heat transfer can influence the droplets heat up rate and consequently their life time. in this paper, the effect of thermal radiation heat transfer is investigated for two cases of directional and spherically symmetric illuminations. the flow and temperature fields insdie and outside o...

This article has focused on evaluation and identification of effective parameters in positioning performance with an odometry approach of an omni-directional mobile robot. Although there has been research in this field, but in this paper, a new approach has been proposed for mobile robot in positioning performance. With respect to experimental investigations of different parameters in omni-dire...

Diagram object detection is the key basis of practical applications such as textbook question answering. Because diagram mainly consists simple lines and color blocks, its visual features are sparser than those natural images. In addition, diagrams usually express diverse knowledge, in which there many low-frequency categories diagrams. These lead to fact that traditional data-driven model not ...

It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...

One purpose of spatial audio is to create perceived virtual sources at various positions in terms direction and distance with respect the listener. The psychoacoustic principle auditory perception essential for creating sources. Currently, technical means recreating different directions techniques are relatively mature. However, control remains a challenging task. This article reviews principle...
