abstract: gridlock is an extreme traffic state where vehicle cannot move at all. this research studies the development of gridlock by theoretical and numerical analysis. it is shown that the development of gridlock can be divided into several stages. the core of the development is the evolution of congestion loop. a congestion loop is comprised of a number of consecutively connected spillover l...

iran’s industry has had a considerable number of difficulties to perform so well as was expected in the post – revolutionary era. unfavorable legal, political environments combined with eight –year imposed war may be singled out as the root causes of such performances. however, this paper argues that our industry’s lack of realization of its dire need to adapt to the emerging unprecedented envi...

At present, the technology of virtual instrument has been developed very quickly in the field of electronic measurement and automatic control. The virtual instrument is a kind of functional instrument combining of software and hardware .This article is from the perspective of exploration and research, and as a reference when encounter hardware problems in the research and development of virtual...

Nonverbal communication is an important part of human communication, including head nodding, eye gaze, proximity and body orientation. Recent research has identified specific patterns nodding linked to conversation, namely mimicry movements at 600 ms delay fast when listening. In this paper, we implemented these behaviour rules in virtual humans, tested the impact behaviours, whether they lead ...
