on this volume, which contained many beautiful drawings and original scientific contributions. The actual inception of the Journal has been recorded by Mr. L. M. Griffiths, for seventeen years Assistant Editor.1 After referring to the preceding Transactions, he continued : " Another four years passed (i.e. 1882) and some members of the Committee thought the time had arrived for the publication ...

We explore the art gallery problem for the special case that the domain (gallery) P is an mpolyomino, a polyform whose cells are m unit squares. We study the combinatorics of guarding polyominoes in terms of the parameter m, in contrast with the traditional parameter n, the number of vertices of P . In particular, we show that ⌊ 3 ⌋ point guards are always sufficient and sometimes necessary to ...

This paper presents an approach to the computational use of drawings through the development of complexity measures, defined as the information content of the description of a drawing’s structure. As such it is the function of the representation used. The paper presents examples of the use of such measurements applied to design drawings of architects.

The practice of using children's human figure drawings (HFDs) to assess their intellectual ability is pervasive among psychologists and therapists in many countries. Since the first systematic scoring system for HFDs was published in 1926, their continued popularity has led to the development of several revised versions of the test. Most recently, the Draw-A-Person Intellectual Ability Test for...

Physiological computing involves the direct interfacing of human physiology and computer technology, i.e. brain–computer interaction (BCI). The goal of physiological computing is to transform bioelectrical signals from the human nervous system into real-time computer input in order to enhance and enrich the interactive experience. Physiological computing has tremendous potential for interactive...

In the present study, we investigated whether expressing emotional states using a simple line drawing to represent a robot's face can serve to elicit altruistic behavior from humans. An experimental investigation was conducted in which human participants interacted with a humanoid robot whose facial expression was shown on an LCD monitor that was mounted as its head (Study 1). Participants were...

A poorly known species of antlions, Omoleon jeanneli Navás, 1936 is redescribed and illustrated with five photos and genitalia drawings. A key for African Dendroleontini is given. This is the first record of O. jeanneli from Kenya.

Since the Sassanid era, many reliefs and seals have left and by reviewing their designs, the mythical and religious attitudes of those people can be understood. The purpose of this article is to decode and interpret the symbolic paintings and to review and study the myths, concepts, and religious rituals of this period. The question is that what the divine and human origin of the symbolic paint...
