The technological progress within the last few years allows the construction of robots that could be part of our everyday live in near future. Besides human like appearance and communication they require natural patterns of behavior and motion to achieve wide acceptance. To analyze human motions we present different kinds of motion capturing systems and post-processing methods for motion data. ...

Unprecedented, non-stop environmental turbulence accompanied by a progressively accelerated rate of change causes deep concern for businesses today. Almost half a century ago, Emery and Trist (1965) recognized the dependency of organizations on their environments and identified the increasing complexity and pace of environmental change. Since that time, Clarke (1994) and others (see below) repe...

This paper addresses two questions relevant to the design of effective locomotion methods for VR using a novel wheelchair motion simulation interface. First, we investigate the extent to which people's ability to keep track of where they are in an immersive virtual environment can be facilitated by actual physical movement (rotation and translation) in the context of vehicular travel. Second, w...

Humans tend to use high-level semantic concepts when querying and browsing multimedia databases; there is thus, a need for systems that extract these concepts and make available annotations for the multimedia data. The system presented in this paper satisfies this need by automatically generating semantic concepts for images from their low-level visual features. The proposed system is built in ...

—Hydroperiod, the time a temporary pond holds water, is an important factor influencing recruitment in amphibian populations and structuring amphibian communities. We conducted an experiment to test the effect of hydroperiod on metamorphic traits of the southern leopard frog (Rana sphenocephala), a common amphibian in the southeastern United States. We reared larval R. sphenocephala in artifici...
