This paper presents the utilization of inertial effect in damping-based posture control of a mobile manipulator. As a measure for redundancy resolution of a mobile manipulator, an effective inertia at the end effector in the operational space is proposed and investigated. By changing the effective inertia property via null-motion, we can get the reduced inertial property of the mobile manipulat...

Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

We show that the class of Boolean contact algebras has the joint embedding property and the amalgamation property, and that the class of connected Boolean contact algebras has the joint embedding property but not the amalgamation property.

This work describes the effect of newly introduced faying surfaces on microstructure and mechanical properties dissimilar weld joints AA6063 AISI304L alloys that are fabricated through rotary friction welding process (RFW). The experiments were done as six different experimental methods (‘A’ to ‘F’) at 1300 rpm rotation, 18 MPa pressure (FP), 24 upset (UP) 5 s time (FT) with hemispherical bowl ...

Arthrosis is synonymous to osteoarthritis (OA) which is common degenerative disease of a joint in elderly and coxarthrosis specifically refer to hip joint osteoarthritis and it can be primary or secondary of which the latter due to other inflammatory joint disorders. Both arthrosis and arthritis shared some common clinical features such as pain and tenderness, stiffness and limited range of joi...
