The effects of seabed reflection on underwater acoustic test is analyzed, through simulating sound field of free...

In the applied process of robot off-line programming technology, it is necessary for the model to solve the correction problem which is between the practical working and off-line simulational environment. Robot coordinate system calibration method is proposed by measuring workpiece coordinate system...

The paper presents a kind of OOA/OOD method about management information system (MIS). The object model includes information model,function model and status model, named IFS model in this paper. These models are controlled by some data. Model Driven Development(MDD) is a kind of model driven, which is...

In order to study the problem of the dimension of the dimension of the model modified design. A geometric model for the layout of dimension dimension. Through the containment relationship between the dimensions of the relationship between the size of the resulting constraint relationship, on the basis...

The bidimensional empirical mode decomposition based on block partitioning(BBEMD) by using of radial basis function interpolation reduces the computational cost, but the blocking artefact is noticeable in the resulting mode. For alleviating the blocking artefact problem, we proposed a modified BBEMD....

This paper studies the effect on the Augmentative and Alternative Communication (AAC) System for communication ability of autistic children. Procedures and Methods: Selecting five autistic children as research subjects, and the single subject experimental method was used to train subjects with the AAC...

The production process of aggregate industrial is monitored by the identification of the digital. In the video, the digital character whose size is less than 12 15(The width of the digital image is 12 pixels, and the height is 15 pixels.) is defined as the small digital. The recognition effect is evaluated...

With the definite labeled samples, it is difficult that avoid the curse of the dimensionality for the accurate and efficient classification of hyperspectral images. It is necessary that reduce the dimensionality of hyperspectral images. Therefore, Polymorphic Ant Colony Algorithm (PACA) based band selection...

Stem water content is an important index of plant water balance. A new method based on changes in ultrasonic properties of stem was used to monitor stem water content in this paper, because the propagation of ultrasonic pulse echo signal and its attenuation characteristics in the material are closely...

Pyroelectric infrared (PIR) sensor is low-cost, low-power small component commonly used only to trigger alarm in presence of humans or moving objects. PIR sensors are widely used as a simple, but reliable. In this paper, we present a novel pyroelectric sensor node, feature extraction method and human...

We adopt suitable numerical method to study the solitary waves of nonlinear Dirac equation in complex system. In some conditions, using nonlinear Dirac equation, we can better describe the macroscopic electrical phenomena and features generated by large amounts of electrons. As a result, we found the...
