The islands have plentiful renewable energy resources. Fully use of these renewable energy sources will greatly improve the power supply capacity and quality of the offshore micro grid. Considering the randomness and intermittence of the output of these renewable energy sources, it is a good choice to add energy storage devices into the grid to improve the reliability and stability of the system output...
As to the research on AspectJ in this context, after analyzing the Java program, AspectJ can realize the capture of the join points based on the Boolean or Compound expression in the Java program. The information includes: the time to judge the runtime condition of each join point as “true” use of the logic AND (&&) to combine pointcuts; and use of the logic OR (‖) to combine pointcuts; all...
As to the research on AspectJ in this context, after analyzing the Java program, AspectJ can realize capturing the information of object-based join points in the Java program. The information includes: the time when this references a specific type problem; the time when the target object of the join point is a specific type; and the time when the parameter of the join point is a digital, type and...
CNC machine is a highly typical mechatronics product which is a set of electronic technology, computer technology, automatic control technology and servo drive technology and precision machinery technology. As an expensive precision machine tool, CNC machine is generally the key enterprises and the critical equipment of the key processes, once the downtime, the impact and losses are often large. Mostly,...
The Natural Element Method (NEM) is a numerical method, which constructs the interpolation based on the Voronoi tesselation of a set of nodes, does not rely on the grid, owns the advantages of meshless method. In NEM, the shape functions meet the properties of KroneckerDelat function, which makes it impose the boundary conditions easily. Based on the advantages of NEM, the elasto-plastic NEM is investigated...
Orthogonal code is one of the key technologies of CDMA communication. The realization of orthogonal code by software offers a method to settle the problem that the transformation and communication among different CDMA code systems. Orthogonal coded method based on dyadic additive group is proposed in this paper. Moreover, it takes binary system for example, a C language program which produces orthogonal...
For the sake of monitoring truck loading imbalance, a truck loading balance detection system based on TPMS (Tire Pressure Monitoring System) is developed. A judging module for loading balance is added in the TPMS processor, which can calculate the corresponding wheel load according to the change of tire pressure signals before and after loading, so that the balance of each wheel load sharing can be...
The battery volume of mobile terminals is limited and in most case it cannot rely on the supplying of external power. Therefore, discontinuous reception mechanism (DRX), a kind of power saving mechanism in mobile communication is introduced in order to reduce the power consumption of battery. In this paper, we discuss and show DRX parameters and features in TD-LTE. By establishing TD-LTE DRX model...
This research found the key affecting factors on e-learning training effect with the use of survey method and analytic hierarchy process (AHP). Through literature research and survey method, we got the factors that affect e-learning training effect from three aspects: organizational factors, E-learning training factors and personal characteristics factors. Then we designed a questionnaire on importance...
