There are different types of insulation materials for applying on a new roof or retrofitting an existing structure.
The measured density and thermal conductivity values of various insulating materials are given in Table 2.
As there are many thermal insulating materials available, its selection is dependent on the thermal conductivity, thickness and typology of walling and roofing materials.

Introduction Radioactive materials are widely used for many purposes in industries and in other areas.
The rules define the conditions for transport of shipment containing radioactive materials.
All three materials had the same density and bulk modulus equal to bulk modulus of water.
These materials were modelled by hex solid elements in FEM analyses.

Study of the Gas Sensor Array based on Micro-Machined Ceramic Hotplate Yanbing Xue 1,2,a, and Zhenan Tang1,b 1School of Electronic Science and Technology, Dalian University of Technology, Dalian, Liaoning 116023, China 2School of Electrical and information Engineering, Dalian Jiao Tong University, Dalian, Liaoning 116028, China adlxyb@djtu.edu.cn, btangza@dlut.edu.cn Keywords: Ceramic hotplate, Gas sensor array, Gas sensitive materials, laser processing Abstract.
Taking ceramic hotplate as heating platform and nano-SnO2 materials with Pd doping concentration of 0.2 at.% and 10 at.% as sensitive materials respectively, the array with two gas sensors was designed and fabricated.
Gas sensor array is composed by coating different sensitive materials on interdigitated electrodes located in the symmetry position on the bridge.

Two kinds of sensitive materials of sensor array are 0.2 at.% and 10 at.% Pd doped SnO2 powders, respectively.

Comparing with classical homogeneous materials, stress concentration at the inner surface of hollow cylinder composed of functionally graded materials can be alleviated.
For functionally graded materials, the elastic ultimate bearing capacity can be improved strikingly by increasing the thickness of cylinder, which is not so obvious for classical homogeneous materials.
Functionally graded materials (FGM) are new advanced composite materials with continuously varying properties in one or multi directions.
