Perceiving which of a scene's objects are adjacent may require selecting them with a limited-capacity attentional process. Previous results support this notion [1-3] but leave open whether the process operates simultaneously on several objects or proceeds one by one. With arrays of colored discs moving together, we first tested the effect of moving the discs faster than the speed limit for foll...

Friction forces acting on rotators may promote their alignment and therefore eliminate degrees of freedom in their movement. The alignment of rotators by friction force was shown by experiments performed with different spinners, demonstrating how friction generates negentropy in a system of rotators. A gas of rigid rotators influenced by friction force is considered. The orientational negentrop...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...

This study investigates the effect of IT-business strategic alignment on organizational agility by considering the effects of IT flexibility and IT capability on strategic alignment. Also this study investigates the moderating role of environmental uncertainty on the relationship between strategic alignment and organizational agility. This research is an applied research based on purpose and de...

Theoretical and experimental results for motion-compensated linear prediction of video signals are presented. T h e rate distortion theory of motion-compensated prediction is extended to linear predictive models. For practical implementations, linear vector predictors are employed. The rate of the motion data is ccmtrolled by minimizing a Lagrangian cost function whore rate is weighted against ...

This paper describes an algorithm for translational motion estimation near a comet surface using scanning laser rangefinder data. Our technique is based terrain map generation from rangefinder data followed by terrain map alignment. The output of our algorithm is estimates of rigid translational motion and motion covariance between scans. Our algorithms have been tested using data acquired with...

Stimuli-sensitive hydrogels have received attention because of their potential applications in various fields. Stimuli-directed motion offers many practical applications, such as in drug delivery systems and actuators. Directed motion of asymmetric hydrogels has long been designed; however, few studies have investigated the motion control of symmetric hydrogels. We designed a pine cone scale-in...
