This paper is an investigation of completely mechanical quick changeable joints for multipurpose explosive ordnance disposal (EOD) robots. With the assistance of a quick changeable joint, an ordinary EOD robot becomes a multipurpose robot with an end effector which can be switched during the task. This exchangeable end effector permits the robot to perform more complex duties. Making the joint ...

Relevance. When the hydraulic fluid is operated for several cycles, impact on performance and longevity greatly increased. So, there are ways to fix this problem. To increase efficiency of system, it necessary study working processes, systems quick-change equipment machine with a lawn k shp made as whole, attached suspension device. The complexity these processes lies in fact that they allow ex...

This paper describes a knowledge-based useroriented interface system which is unique in its combined use of data base, graphics, and AI technologies. All of the data presented to the user, as well as all of the data input by the user, is maintained and used as abstract “objects” using an AI object-oriented knowledge representation approach. However, the system employs a relational data base as ...

A novel audio protection and authentication scheme is proposed in this paper. By quantizing a host audio’s FFTcoefficients as masking threshold units (MTUs), two complementary watermarks are designed and embedded using our cocktail watermarking method. For audio protection, high robustness can be achieved; whereas for audio authentication, tampered regions can be detected. Both of the above men...
