THE PROJECT OF TANK INSPECTION ROBOT Mariusz Giergiel1, a, Tomasz Buratowski1,b, Piotr Małka1,c, Krzysztof Kurc2,d, Piotr Kohut1,e,Konrad Majkut1,f, 1AGH University of Science and Technology, 30-059 Cracow Mickiewicza 30 Avenue, Poland 2Rzeszow University of Technology, 35-959 Rzeszow Wincentego Pola 2 Street, Poland agiergiel@agh.edu.pl, btburatow@agh.edu.pl, cmalka@agh.edu.pl, dkkurc@prz.edu.pl, epko@agh.edu.pl, fkmajkut@agh.edu.pl Keywords: Mobile robot, inspection robot, robot for tanks inspection, robot for diagnostics of tanks, underwater robot.
All these examples are introduced to show, that robot constructed by AGH University of Science and Technology unites all positive features of the mentioned robots like flexible ability of motion in metal/concrete tanks, modular construction which allows not only inspection function but – with usage of cleaning module – cleaning tanks’ bottom.
It’s simplicity has influence on low costs of material and manufacturing.

Then main causes were identified and some measures were taken into consideration; relevant circumstances are described below [2]. 1 Tests of traction and dynamic performance for DF 8B locomotive In order to test the DF 8B locomotive performance, according to the Ministry of Railways, Ministry of Science and Technology Division and Product Quality Supervision and Inspection Center of the arrangements, the prototype for a series of identification tests, there are cab noise tests, stand-alone emergency braking distance trials, locomotive weighing, traction performance, dynamic performance tests and other items of identification.
In addition to idling and sliding effects, wheel tread quickly wear also is effected by locomotive axle load, wheel-week traction, wheel hardness and sand material hardness 2) Locomotive idling and taxiing have been decreased for software improvements, and it can curb wheel out of round by the abnormal wear which is caused by locomotive idling.

A wide range of abrasive materials is used in the CMP processes.
Note, that to estimate the crack opening one can neglect by a difference of deformation properties of contacting materials loading to some tangential forces.

Adjust the Tactics of Popularizing Low-carbon Consumption to Civilian Thinking Characteristics Youzhu Li1,2,a 1Business School of Sichuan University, Cheng Du ,610064, China 2Computer Science College of Sichuan Normal University, Cheng Du 610066, China ayoyoli_ok@126.com Keywords: Low-carbon; consumption; thinking characteristics; tactics Abstract.
Pan Anmin said, the patterns of urban low-carbon choice principle of spending "Science, Conservation, Environmental protection and pleasure "[1].Liu Yaming advised, the low-carbon consumption is more inclined to focus the justice of consumption and weaken the freedom of consumption [2].
It is based on harmony of material consumption, spiritual consumption and cultural consumption [8]; to propagandize the significance of popularizing the low-carbon consumption; to emphasize on popularizing the low-carbon products.
