After introducing the wireless network communication technology ZigBee and the features, advantages and application rule of the wireless single chip microcomputer cc2430, which is a true system-on-chip (SOC) loading ZigBee technology, the article introduced the design method of mine alarm system based on ZigBee technology. The composition of the mine alarm system and the design features of hardware...
A design method of low power anti-collision RFID system is presented in this paper. The system power consumption is effectively reduced by circuit design and work mode selecting. An improved anti-collision algorithm is used in the system, reducing both the tag collision probability and the power consumption. The design method has been used in a 433MHz RFID system, enhancing the identification efficiency...
Warehouse is an important part of logistics which becomes a hot research topic. However, the existing warehouse management system has exposed certain technical weakness. In this paper, an adaptive communication framework of the warehouse management system based on RFID (radio frequency identification) and WSN (wireless sensor networks) was proposed. Three forms of network architecture that combines...
In this paper, considering the imperfect (incomplete, imprecise, uncertain, inconsistent) information sources in information fusion, To avoid and reduce the influence of the mistaken or misleading information on the final precision of fusion, the ESMS (evidence supporting measure of similarity) filter is designed and added to generalized fusion machine (GFM), and an ESMS function (not unique) to select...
With the development of robot to intelligent direction, the research of robotic control has become the focus. In this paper, a navigation system of mobile manipulator is designed, fuzzy control theory and artificial neural network are applied. And study basic arithmetic of image processing, use various image pre-treatment and segmentation technology. The main research result of the paper is as follows:...
This paper proposes a new approach to detect the falling of the elderly based on intelligent space. The system can recognize the falling action by use of multi-sensor information in intelligent space. The detection system uses the image processing system to process images which captured from camera. After the silhouettes are obtained, we extract features that recognition falling needs. The surroundings...
Canny Arithmetic Operator has been proved to be a traditional operator possessing a better detective effect in the common usage of edge detection algorithm currently. However, Canny Operator also has certain deficiencies, such as choices of dimensions and Threshold Limit Values. When the dimension is bigger, effect of noise to the edge is smaller, but the locating accuracy will be lost. Whereas, when...
First, trend of development of container ports is described in this thesis. Then, some economic theory in port planning, mathematical methods in optimization of transportation networks, and relevant research about application of game theory on transportation are concluded. The principle of competition in port market is analyzed and the interactive relationship among port authority, carrier and shipper...
The effective configuration and supply of global resources have become the focus of market competition under the circumstances of globalized economy and internationalized market. The supply chain management serves as the basis to enable the enterprises to win in the competition and it is the key to improving enterprisespsila core competitive power. In order to handle better in the heated competition...
Nowadays, the global ship market is so competitive that shipbuilding supply chain is being more and more important for modern shipbuilding enterprises to survive. Shipbuilding process is very complicated, and its partners are numerous, which brings about many risks in the shipbuilding supply chain. How to effectively control all the risks becomes a matter of life and death for all the shipbuilding...
This paper designs supply chain network in uncertain environment, in which the demands of customers are assumed to be random variables, and the operation costs are considered as fuzzy numbers. After modeling by fuzzy programming, a fuzzy neural network optimized by particle swarm optimization is presented to solve the established model. Through an example, compared with the traditional fuzzy neural...
The auto part suppliers are the source of the automotive supply chain and play an important role in the manufacture resources. Its behaviour is closely related with the market and the quality. Its achievement directly affects the product quality, the marketing ability of the auto company, and the customer satisfaction. The article discusses the auto part supplierspsila evaluation criteria, which are...
The vesselspsila arriving law is generally considered to obey Poisson distribution, and inter-arrival time is used to be considered to accord with negative exponential distribution, which fit general cargo transport mode well. However, it will induce significant error if we apply this law into vesselspsila arrival in container transport mode. Itpsilas because that general cargo transport is constitutionally...
Discussing the impact of environmental factors in the supply chain management is a hot issue at home and abroad. This paper begins with a brief analysis of the contents of green supply chain management and the obstacles in the environmental management process. Then we do some research on how to carry green supply chain management out considering environmental management systems, by environmental management...
With the development of the global business and logisticspsila a container terminal (CT) system becomes more and more busy. Therefore, the available resources in the sea port get scarcer than before. In order to increase the operating efficiency of CT system, the resources planning problem has become a critical issue in the fields of operations research and logistics. In this paper, we introduce the...
Interpolating algorithm strategy of multi spindle linkage is analyzed including line and arc rough and fine interpolation method. Cubic B spline is used as fine interpolating algorithm and error evaluation of arc interpolating algorithm is presented. This algorithm model is sample and can be used in many situations. Interpolation is the method, that is, CNC calculates all movement vectors according...
Adaptive beamforming is known to have resolution and interference rejection capability when the array steering vector is precisely known. However, the performance of adaptive beamforming techniques may degrade severely in the presence of mismatches between the assumed array response and the true array response. In this paper, we propose a novel neural network approach to robust adaptive beamforming...
Genetic Algorithms (GAs) have demonstrated to be effective procedures for solving multi criterion optimization problems. These algorithms mimic models of natural evolution and have the ability to adaptively search large spaces in near-optimal ways. One direct application of GAs is in the area of evolutionary robotics, but standard GAs have some drawbacks such as time-consuming and premature convergence...
Based on the fruits of authorspsila researching on vessel automatic anti-collision in the past decade, discussed the connotation of the dasiaPersonifying Intelligent Decision-making for Vessel Collision Avoidance (PIDVCA for short)psila, brought forward the researching aim of the PIDVCA. And then according to the procedure of vessel anti-avoidance, put forward the science idea and framework of the...
Considering the issues that the energy saving process for beam-pumping unit is a complicated and nonlinear system, and it is very difficult to found the process model to describe it.
