Shape from focus is an accurate, but relatively time-consuming, 3D profilometry technique (compared to e.g., laser triangulation or fringe projection). This the case because a large amount of data that needs be captured and processed obtain measurements. In this paper, we propose two-step shape-from-focus measurement approach can improve speed with 40%. By using faster create coarse unknown tar...

Shape priming was studied in four experiments comprising a complex search task in which subjects searched for a target shape presented among three distractors and reported the location of the target. Localization performance improved as a function of the duration of stimulus exposure and prime lead time. The efficiency of shape primes in improving performance decreased when lateral masks were p...

Subliminal motor priming effects in the masked prime paradigm can only be obtained when primes are part of the task set. In 2 experiments, the authors investigated whether the relevant task set feature needs to be explicitly instructed or could be extracted automatically in an incidental learning paradigm. Primes and targets were symmetrical arrows, with target color, not shape, the response-re...

This work performs the analysis and simulation investigations of penetration behaviors of chisel-shape projectile. In analysis, the projectile is assumed to be a rigid body and the target plate is elastic-plastic material. By introducing the velocity potential function, the velocity field in target is first obtained. Then, the momentum equation is solved for determining the pressure and stress ...

In this paper, we propose a distance-based formation control strategy for a group of mobile agents to achieve almost global convergence to a target formation shape provided that the formation is represented by a complete graph, and each agent is governed by a single-integrator model. The fundamental idea of achieving almost global convergence is to use a virtual formation of which the dimension...

Extracting and transforming shape features has been an important research domain in wheel hub design. The study of design based on semantics, brand planning, structural optimization requires regression analysis by using the corresponding variables to guide through correlation model. practical role feature transformation is determined its effectiveness, accuracy, convenience. This process, howev...
