Controlling the motion of multiple miniature objects independently and simultaneously is a grand challenge in microrobotics. In this paper, we report our recent achievements in acoustic manipulation that can control the motion of multiple objects simultaneously and independently on a centrally actuated vibrating plate. By employing spatially highly nonlinear excitation fields on the plate, we can...
With the rapid growth of the number of papers, the traditional methods of searching papers by scholar search engine are becoming unacceptable. These methods can't meet the needs of users and users still need to take a lot of time to filter the search results. To solve the problem, this paper uses the concepts and methods of community partition and introduces a model to recommend authoritative papers...
Using shape information has gained increasing concerns in the task of image labeling. In this paper, we present a dynamic hybrid Markov random field (DHMRF), which explicitly captures middle-level object shape and low-level visual appearance (e.g., texture and color) for image labeling. Each node in DHMRF is described by either a deformable template or an appearance model as visual prototype. On the...
In order to improve detection efficiency of on-line web news stream, we propose a new method to accomplish detection task with window-adding, named entity recognition and suffix tree clustering. In our method, we make full use of informative elements of news stream(such as date, place, person and so on) to help detection process, and this method decreases text similarity computation greatly. Experimental...
In the present study, a series of terminal ballistics numerical analysis and experiments were performed to investigate the process for explosion load drive the based-water extinguisher dispersed. In the Numerical simulation, for the representative fire extinguishing warhead, the simulation model was built, The variety rule between the loading coefficient (drive charge divide liquid mass) and the breach...
A fuzzy neural network (FNN) multi-step prediction model based on singular spectrum analysis (SSA) and mean generating function (MGF) for summer precipitation has been developed in this paper. In the modeling process, the original standardized sample series of summer precipitation was denoised and reconstructed with SSA, the extended matrix of MGF of the reconstructed precipitation series (as the...
