Supplying sufficient early reflections to audience members is an important prerequisite to good acoustic quality in performing arts spaces. However, the relationship between the geometry of a room and its acoustic efficiency in terms of early energy has rarely been investigated using basic geometrical principles. The present study demonstrates the possibility of predicting the average value of ...

outh America’s most famous forms of martial arts are, arguably, Brazilian jiujitsu (adapted from traditional Japanese Judo by a Brazilian family in the 1920s), and capoeira, an African descendant form that encompasses dance, music, and (mostly) non-contact athletic acrobatics.

Ki (in Japanese) or Qi (in Chinese) is the key concept in Eastern medicine, Eastern philosophy, as well as in martial arts. We explain the philosophical and psychological background of Ki. We emphasize that the unique aspects of Eastern philosophy are 'non-linearity' and 'holistic' approach. We then present physics aspect of Ki. Our experiments demonstrated that a 'Ki-beam' carries 'entropy' (o...

The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between t...

In the present study, we assert that pictures serve four functions in problem solving: decorative, representational, organizational and informational. We, therefore, investigate the effects of pictures based on their functions in mathematical problem solving (MPS), by high achievement students of Grade 6 in Cyprus, in a communication setting. A number of tasks were developed and techniques of o...

In this paper two approaches of general applicability for placing fragments of important archeological objects in their proper position are presented. Both methods are based on the thematic content of the drawings depicted on fragments of 1650 B.C. wall-paintings, excavated at the Greek island of Thera. The first method employs the statistical nature of the drawn figures’ dimensions and gives a...
