Thermoelectric modules are made of semiconductor materials and sealed between two plates.
Thus, the thermoelectric modules are made by semiconductors materials, sealed between two plates through which a direct current keeps one plate hot and the other cold.

The producing method of oil absorbent felt using recycled polyester bottle flakes is discussed, emphasizing on processes parameters such as dryness, filtration, spinning technique, drawing ratio, and etc. 1 Introduction In recent years, with the development of waterproof building materials, there has been much change in waterproof building materials and technology.
And this performance PSF showed high break strength and satisfied tenacity. 2 Experimental Section 2.1Production process Materials: Recycled polyester bottle flakes material: recycled crushing flakes materials, such as PET mineral water bottles, coke bottle, limiting viscosity ≥0.70 dl/g, melting point≥250 oC, moisture contents ≤3%. 3.5‰ polyester staple fiber oil, 4% polyester staple fiber oil.
If the temperature is lower, the water of recycled polyester bottle flakes materials cannot be removed, or if a higher temperature is used, the material will be prone to yellow due to the degradation of fiber.
The recycled polyester bottle flakes materials had a lower melting point than normal polyester for the higher internal impurity content, that is the reason why the spinning temperature is usually 275 oC.

Database System The database system is developed with Microsoft SQL Server and consists of five separate groups of data concerning workpiece materials, tool materials, cutting tools, cutting parameters and machining processes, respectively.
The first group (materials database) allows the user to select the workpiece material and its properties.
The materials database is made up of different material classes such as steels, cast irons and aluminum alloys, and within each group there are various materials.
The second group consists of tool materials types such as PCD, PCBN, ceramics, coated cemented carbines, etc.

The empirical method is generally based on the earthquake damage report of buildings, and applied to the structure which has abundant seismic damage materials.
However, the analysis method is applied to the building which has scarce seismic damage materials [2].
