Introduction Advanced optomechatronic systems are characterised by the complexity of their structure that reflects the synergistic integration of solutions developed in the multidisciplinary area of engineering and technology, particularly in mechatronics, optics and optoelectronics as well as in computer-based control systems.
When solving design problems at conceptual and embodiment design stages, more satisfactory results can be obtained using the advanced solution finding methods [7].
Among numerous methods, TOPSIS technique has been successfully applied to solve decision problems in various areas of engineering and management.

Following the advancing technologies of magnesium smelting, high pressure processing, surface treatment and soldering since 1990's, the prices of magnesium and its ingot stepped down.
As an important light engineering material, magnesium application is growing at annual speed of 15%, much higher than aluminum, copper, zinc, nickel and steel.

Principle of Theory and Practice Advancing together Through investigation of the present situation of distance education in 68 pilot universities in China, we find that the proportion of theoretical coursewares is larger than practical those[3], which leads the common fault of learners having a poor practical ability.
So when we are designing the web-based coursewares, we should follow the principle of theory and practice advancing together and make full use of modern technology to make the coursewares more rich, novel and operable.
Principle of Engineering Problems “Literarized” and Literary Problems Dramatized The view of “Engineering Problems ‘Literarized’ and Literary Problems Dramatized” [4] is put forward by professor Li Xiaoping who is from the school of modern distance education in Beijing Institute of Technology.
Therefore, when we design the coursewares, we should pay more attention to its interest and treat the engineering problems with literary view and treat the literary problems with dramatic view.
For example, when we prepare for shooting a historic courseware, we usually choose the form of forum and select a speaker who can command the overall situation.

The fire smoke exhausting robot produced by the Shanghai Fire Institute of Ministry of Public Security is the most advanced equipment in this area.

The alloy was hydrogenated to concentration of ~1 % (hereinafter, the hydrogen concentration is indicated in weight percent) using the automatic Gas Reaction Controller LPB (Advanced Materials Corporation, USA) [11].
Hydrogen content in the alloy in both states decrease to values corresponding engineering standards for titanium Ti-6Al-64V alloy.
Thus, use of the electron beam in combination with heating for hydrogen degassing of titanium alloys allows reduce the hydrogen concentration to a value closed to the engineering standards for these alloys.

Experimental and numerical investigations of TBC behaviour after aging, subjected to tension and bending Tomasz Sadowski1, a, Przemysław Golewski1,b 1Faculty of Civil Engineering and Architecture, Lublin University of Technology, Nadbystrzycka 38, 20-618 Lublin, Poland asadowski.t@gmail.com, bpgolewski@gmail.com Keywords: thermal barrier coating system, brittle cracking, thermal aging.
Advanced ceramic materials made of 2 phases are good examples for modern applications [1-3].
The obtained experimental results allow to perform advanced numerical modelling in the Abaqus including 3 different degradation processes.
Different level of advanced damage description was used as Fig. 8 shows.
The best results are achieved for the most advanced description, which takes into account both the damage of the TC and the BC (brittle cracking) and further - delamination caused by the growth of the TGO layer (cohesive surface).
