With the quick improvement of equipment, fabrics technological know-how and Engineering program, dialogue on new principles related mechanical engineering and fabrics technology come up. during this court cases quantity the author(s) are focussed on equipment, fabrics technological know-how and Engineering purposes and different comparable themes. The Conference has supplied a worthy chance for researchers ,scholars and scientists to switch their rules. The convention association goals to bolster nationwide educational exchanges and cooperations within the box, advertise the quick improvement of equipment, fabrics technology and engineering software, successfully enhance educational prestige and overseas effect of China's equipment, fabrics technology and engineering functions and play an energetic position to minimize the space among family comparable disciplines and foreign issues.

Engineering Education and Management: Vol 2, Results of the 2011 International Conference on Engineering Education and Management (ICEEM2011)

This is often the court cases of the chosen papers provided at 2011 foreign convention on Engineering schooling and administration (ICEEM2011) held in Guangzhou, China, in the course of November 18-20, 2011. ICEEM2011 is without doubt one of the most crucial meetings within the box of Engineering schooling and administration and is co-organized by way of Guangzhou college, The college of latest South Wales, Zhejiang college and Xi’an Jiaotong college.

Example text

UF_initialize is an initialization function. When secondary development began to call the function of UG/Open API, it should be first call the UF_initialize to obtain execute permissions. UF_terminate is a termination function, when secondary development will not use UG/Open API function, it must first call the UF_terminate to release the execute permissions. 3 Access to quality attributes Moment of inertia, mass and center position of missile can be used as a basis for the quality of aerodynamic performance calculation, ballistic calculation, load calculation, stability and maneuverability calculation, structure design, the design of transmission device and missile transportation loading equipment.

According to the symptoms value yij of fault j, the feature vector Yj = (y1j, y2j, … ymj) of the fault can be got and fault knowledge library can be established. 4 FAULT DIAGNOSIS MODEL Suppose the fault to be identified is labeled as u0, characteristic vector of fault u0 is Y0 = (y1, y2, … ym). The membership function which identify whether u0 is fault j is as follow: μ j (u ) m ∑y y i ij (7) i =1 According to the principle of maximum membership, u0 is the fault corresponding to the maximum of μ1(u0), μ2(u0) … μn(u0).

5 Flow chart. We denote the air pressure measurement range of the voltage-type sensor by Pmax and Pmin, and accordingly, the output voltage range is denoted by Vmax and Vmin, so we can calculate the theoretical output voltage of the sensor that denotes as Vcalculate according to the pressure value which calculates by equation (5). Vcalculate = Vmin + (Pressure-Pmin)*(Vmax − Vmin)/(Pmax − Pmin˜) (6) The computer will compare the experimental output voltage of each sensor with the theoretical result which calculates by equation (6), it will estimate the senor to be OK if the error is within the permissible range, otherwise the sensor is failure.
