Long-range dependence in human movements: detection, interpretation, and modeling perspectives
نویسندگان
چکیده
This symposium is conceived as a complement to the keynote proposed by Jeffrey Hausdorff, and focused on long-range dependence in human movement. 1/f noise, or fractal fluctuations, have been discovered in a number of empirical phenomena, and remain an intriguing property, characterized by long-range dependence and self-similarity. In the domain of motor behavior, fractals have been evidenced, for example, in tapping, forearm oscillations, bimanual coordination, or step duration during locomotion. This fractal dynamics was frequently presented as the natural outcome of complex systems, but the principles underlying its generation remain controversial (Wagenmakers, Farrell & Ratcliff, 2004).

Blinking and eye movement are one of the most important abilities that most people have, even people with spinal cord problem. By using this ability these people could handle some of their activities such as moving their wheelchair without the help of others. One of the most important fields in Human-Robot Interaction is the development of artificial limbs working with brain signals. The purpos...

Climate changes pose great threats to the main services of ecosystems such as food security, water security and health. This research was carried out in Haraz river basin rangelands, Mazandaran province in the north of Iran in 2015-2017 to analyze the perspectives of Haraz river basin (HRB) pastoralists about climate change. From 5236 local pastoralists, the sample size was consisted of 350 one...

The school of Tafkik (separation) argues that religious knowledge and human science, especially philosophy and mysticism, are two detached areas. This school has some views about the interpretation of Quran and the role of tradition on it which is required to be investigated and analyzed. Although this school refers to Ijtihadi approach as a legitimate method in interpretation, it rejects this ...

An electrochemical method employing a carbon nanocomposite electrode was developed to measure thioridazine. The electrode has been designed by incorporation of montmorillonite nanoclay into the carbon ionic liquid electrode. Surface morphology of the electrodes was done using scanning electron microscopy. Adsorptive stripping voltammetry was applied as a very sensitive analytical method for...
