Devanagari script is a two dimensional composition of symbols. It is highly cumbersome to treat each composite character as a separate atomic symbol because such combinations are very large in number. This paper presents a two pass algorithm for the segmentation and decomposition of Devanagari composite characters/symbols into their constituent symbols. The proposed algorithm extensively uses s...

We consider contact representations of graphs where vertices are represented by cuboids, i.e. interior-disjoint axis-aligned boxes in 3D space. Edges are represented by a proper contact between the cuboids representing their endvertices. Two cuboids make a proper contact if they intersect and their intersection is a non-zero area rectangle contained in the boundary of both. We study representat...

The Carpenter’s Rule Theorem states that any chain linkage in the plane can be folded continuously between any two configurations while preserving the bar lengths and without the bars crossing. However, this theorem applies only to strictly simple configurations, where bars intersect only at their common endpoints. We generalize the theorem to self-touching configurations, where bars can touch ...

In recognizing characters written on forms, it often happens that characters overlap with pre-printed form lines. In order to recognize overlapped characters, removal of the line and restoration of the broken character strokes caused by line removal are generally conducted. But it is not easy to restore the broken character strokes accurately especially when the direction of the line and the ch...

The concrete experience of physical warmth has been demonstrated to promote interpersonal warmth. This well-documented link, however, tells only half of the story. In the current study, we thus examined whether physical coldness can also increase interpersonal warmth under certain circumstances. We conducted three experiments to demonstrate that the relationship between the experience of physic...

We studied behavioral responses of the cricket, Gryllus bimaculatus, to mechanical stimulation of the hindwing tip using three different kinds of stimuli: touching, bending and pinching. The most characteristic was a sequence of initial jump-like movements and subsequent running steps, that is referred to as escape behavior in this study. Touching stimulus elicited the escape behavior in 52% of...

Anticipating the sensorimotor consequences of an action for both self and other is fundamental for action coordination when individuals socially interact. Somatosensation constitutes an elementary component of social cognition and sensorimotor prediction, but its functions in active social behavior remain unclear. We hypothesized that the somatosensory system contributes to social haptic behavi...
