Natural control of spring-like running: Optimised selfstabilisation

In this study, the influence of leg rotation during the swing phase on the stability of running is addressed. Therefore, conservative spring-mass running was investigated using a return map of the apex height. A fixed angle of attack can already result in selfstabilised running as found previously. By examining the return maps of all possible angles of attack, a rotational leg control is derive...

Running head: AWE, NATURE Awe and the Natural Environment

Theoretical accounts have suggested two central features that underlie the prototypical experience of awe: vastness and accommodation (Keltner & Haidt, 2003). Guided by this analysis, in the first section we discuss the prominent role of nature as an elicitor of awe. Second, we provide a review of recent research that has clarified the appraisals, facial and vocal displays, physiological, and p...

Natural dynamics of spring-like running: Emergence of selfstability

In this study, the stability of conservative spring-mass running using a fixed angle of attack is addressed. For a given initial condition, different angles of attack result in periodic movement patterns. We apply a simple stride-to-stride analysis to prove the stability. Spring-like leg operation together with angle of attack control enables selfstabilised running.

Running head: SUN SUN: Top-down saliency using natural statistics

When people try to find particular objects in natural scenes they make extensive use of knowledge about how and where objects tend to appear in a scene. Although many forms of such “top-down” knowledge have been incorporated into saliency map models of visual search, surprisingly, the role of object appearance has been infrequently investigated. Here we present an appearance based saliency mode...
