The influence of velocity of oil debris on the sensitivity in metal debris counting with microfluidic oil detection chip is reported in this paper. A microfluidic oil detection chip of a three-dimension solenoid with a micro channel crossing its center was presented in this paper. When measuring the inductance value of microfluidic oil detection chip caused by the oil debris, it can be found that...
Accurate detection of metallic wear debris is vital to avoid catastrophic failure of machine. An inductive metallic debris sensor in accordance with the theory of electromagnetism is presented to discuss the relationship between the sensitivity of inductive sensor and the position of microchannel inside the planar coil. Iron particles with 110–120µm in diameter are used in the experiment and the result...
The effect of marine environment on the ship dynamic positioning (DP) systems is the foundation of performing control law design and the necessary step. In order to effectively calculate the effect acted on dynamic positioned ship by ocean environment, mathematical model of the ocean environmental disturbances include wave and wind was established. Based on the Matlab/Simulink, a simulation platform...
Manufacturing logistics management consists of complex interconnections among manufacturing processes, facilities, warehouses, quality controlling, packaging and logistics. In recent years, RFID (Radio Frequency Identification) technology has become so matured that it has been widely applied on manufacturing logistics management. Firstly, this paper presents the significant potential of RFID application...
The emphases of the study on IT competition value in enterprises have begun to transform from strategic information system, which is the carrier of achieving competitive advantage, to IT capability construction. The core of this transformation is how to obtain sustainable competitive advantage. This paper illustrates this by analyzing two leading retailing companies in the world, Wal-Mart and Japan...
With the rapid pace of IT revolution, companies are getting closely tied and their relationships are gone from competition to cooperation in order to achieve a win-win deal. However, The EACS in China, represented by GOME and SUNING, are performing far from satisfaction. They are still in the stage of depressing manufacturers for lower cost by their channel advantage accumulated over years. Now, management...
A control strategy, constant power and variable power combination control (CVCC), was put forward for integrated hydraulic propulsion (IHP) ship against its characteristics. Theoretical analysis was conducted through working condition matching characteristic charts to evaluate the effect of this control strategy. Modeling and simulation of IHP ship was researched, and the theoretical analysis results...
A ship propulsion method, integrated hydraulic propulsion (IHP), was put forward and its characteristic was discussed. After that, dynamic mathematic model of IHP vessel was developed. Based on the model, dynamic response character of the system and the influences of four parameters (oil bulk modulus, rotary inertia, seawater density and oil temperature) upon the system were discussed. The simulation...
