Experimental study of the thermal insulation property of sedum linear roof module in real weather condition in Guangzhou, China Wang Zhangyuan1,a, Qiu Feng1, Yang Wansheng1,2 1School of Civil and Transportation Engineering, Guangdong University of Technology, Guangzhou 510006, China; 2State Key Laboratory of Subtropical Building Science, South China University of Technology, Guangzhou 510640, China azwang@gdut.edu.cn Keywords: green roof module; thermal insulation; comparative study Abstract.
Substrates used on roofs have primarily been based on natural soil mixes or recycled materials [3].
The aims of the tests are to obtain the thermal insulation properties of the four modules, which will provide solid experimental results for the use of the green modules in practical engineering projects and be especially useful for industrial purposes, as well as for design, city planning and research applications at green roof sites.
The testing was operated at the Outdoor Testing Field, Structural Laboratory, School of Civil and Transportation Engineering, Guangdong University of Technology, Guangzhou, China from 1st July to 5th September 2012.

From the sighure ,exports above(that is vertical, horizontal life cycle) build jointly a research framework of environment sectors and ecological problems to process industry-related resources, this study can be said PISEA key point, understand the cross-coupling of two lives cycle compound derived from the environment, making PISEA study more in-depth research, thorough, complete and systems.
No doubt, PISEA study involved longitudinal and transverse cross-coupling studies of life cycle, the basic theoretical foundation for the subject of environmental science, environmental science, but here is the process industrial development through the process of the link system and a set of relationships and social sciences, engineering sciences so integrated and applied PISEA, we can say that any support related disciplines study are effectiveness in PISEA.
In the relevant process, people's views or proposals will be subject to all relevant factors, such as the level of environmental engineering technology, solve real environmental problems underlying technical feasibility, environmental values’identity,and so on.

a badrinathan@hotmail.com, b karun@annauniv.edu Key words: End milling, Progressive feed rate, Tool wear, Design of Experiments (DOE), ANOVA Abstract - This study focuses on the effect of cutting parameters on the tool wear in a CNC end milling operation.
Krain et al. [6] in their experimental work evaluated the effect of feed rate, radial depth of cut, tool material and tool geometry on the tool life and tool wear during end milling of Inconel 718.
This instant acceleration creates high cutting forces and large material removal rate which in turn leads to the increased tool wear.

Materials The materials used for this study are 22MnB5 Al-Si coated steel for metal adherend, BETAMATE 2098 as adhesive and a carbon based consolidated composite laminate as fiber reinforced plastic (FRP) adhesive.
The tensile strength of hot stamped specimen is for the investigated dwell times and temperatures above 1,400 MPa, verifying no sensitivity of varied process parameter to hot stamped material characteristics.

Among them, the minimum thickness t is the key parameter of flexible hinge, the value of t is smaller, the sensitivity and resolution factor are higher and magnify ability is bigger.
Hypothesis that the material of the mechanism is 65Mns, take the projected dimension into the equation (1), (2) we can get: T=14.5 K=5.66N.m/r.
