With the increasing task demand for complex system, the timeliness of the system is becoming a prominent problem, especially in the inefficient system and may even lead to safety problems. This paper proposes a modeling method considering the issue of timeliness for complex system, in which the clock...

The traditional magnetic measurement method is based on the magnetic dipole model that is a point model, and the shape information of the target cannot be determined, resulting in high false alarm rate and low detection efficiency. In this paper, a magnetic multi-order pole expansion model is proposed,...

It is management software that considers various types...

Searching music by emotion has always been strongly needed by users. Since music streaming applications usually have tens millions of music pieces in database, it is impossible to label emotion tags for each music piece manually. It is desired that an intelligent algorithm can recognize emotion expressed...

Nowadays educational robots have begun to walk into campuses and households, changing the traditional way of teaching and learning. There are many physical or virtual robot education platforms on the market now, whose perfect systems and mature hardware or software not only reduced the difficulty of...

Logistics equipment training is an important means to improve the logistics business level. The traditional training method has high training cost, high equipment loss and is vulnerable to the external environment. Using virtual reality technology to establish a realistic training simulation environment...

In a series of non-axisymmetric well-hole sound filed, besides judging the channelling type according to characteristics of different sound fields, judgment of cement deficiency position of channelling well-hole is also important. The essay put forward to arrange a series of receivers around the wall...

We represent a new approach to testing of spacecraft onboard equipment’s functional control using simulation model’s knowledge base for test procedures’ generation. It allows to analyze characteristics of the objects under study using software models with further creation of real equipment’s testing...

In this paper, we propose an adaptive inter-carrier interference (ICI) mitigation algorithm based on phase rotated conjugate cancellation (PRCC) scheme. For the MIMO-OFDM systems in high-speed train (HST) environment, the ICI is caused by the non-stationary time-varying channels. By updating the optimal...

As an additive manufacturing technology, based on a computerized 3D design model, 3D printing is mainly composed of high-precision mechanical systems, numerical control systems, injection systems, and computer technology. The software is layered discretely and numerically controlled to create a physical...

Even though the ship was designed and constructed by applying the current IMO (International Maritime Organization, here in after “IMO”) stability standard "IS CODE 2008", it has been found that the ship can be capsized due to the waves even in the static condition due to frequent accidents in the ocean....

Aiming at the problems that current methods of flow measurements for partially filled pipe are difficult to measure flow at low liquid level , install and maintain, the new measured method for partially filled pipe is proposed. The liquid level is got by using a high-precision pressure sensor that is...

The management of medical waste stream is an important issue of social concern. Based on the cooperative game theory, the cooperative game evolution model of the three-level hospital group and the basic hospital group is constructed. The Netlogo multi-agent simulation tool is used to analyze the behavioral...

To provide exact mechanics input for anti-high-overload optimal design of penetration projectile, a projectile-target response model was built. On the basis of force analysis for penetration process, the rigid body motion model for projectile was established by adopting Newton’s second law. Then, numerical...

This paper presents a device simulation study on a high-voltage 4-cell IGBT structure with a distributed gate resistance. It is shown that during turn-off, the emitter current of IGBT will demonstrate a “homogenous– non- homogeneous– re- homogeneous” evolution before the collector voltage rises. Therefore...

There are some problems in the planning of electric energy substitution, such as the disconnection between headquarters planning and provincial planning, the disconnection between provincial planning and the unscientific measurement. To release them, a two-layer planning model is proposed, with which...
