Design & Kinematic Analysis Of An Articulated Robotic Manipulator, Elias Eliot, B.B.V.L. Deepak, D.R. Parhi, J. Srinivas

International Journal of Mechanical and Industrial Engineering

This paper describes the design, fabrication and analysis a five axes articulated robotic manipulator. The current work is undertaken by considering various commercially available robotic kits to design and fabricate a five degree of freedom (D.O.F) arm. Forward kinematic model has been presented in order to determine the end effectors position and orientation. Although this work is still in primary level, this analysis is useful for path tracking of an industrial manipulator with pick-and-place application. Based on this analysis, a researcher can develop path tracking behaviour of an end effector in complicated work space.

Optimization Of Orthopaedic Drilling: A Taguchi Approach, Rupesh Kumar Pandey, S.S. Panda

International Journal of Mechanical and Industrial Engineering

Bone drilling is a common procedure to prepare an implant site during orthopaedic surgery. An increase in temperature during such a procedure can result in thermal ostenecrosis which may delay healing or reduce the stability of the fixation. Therefore it is important to minimize the thermal invasion of bone during drilling. The Taguchi method has been applied to investigate the optimal combination of drill diameter, feed rate and spindle speed in dry drilling of Polymethylmethacrylate (PMMA) for minimizing the temperature produced.

Demultiplex The Ssb Signal Without The Interferences Between The Even And The Odd Subchannels, Mrs. Ranjita Rout, Jagan Bihari Padhy

International Journal of Electronics and Electical Engineering

This letter studies the interference between the even and the odd subchannels in the interleaved multiplexing optical fast orthogonal frequency-division multiplexing system, which is caused by the non-orthogonal demultiplexing transform at the receiver. To eliminate this interference, frequency and timing off-sets are introduced deliberately at the receiver to form orthogonal bases, which coincide with the discrete cosine and sine transforms of type- IV. Thus, the symbols can be demultiplexed at the receiver without any interference between subchannels, and the proposed receiver design can be implemented efficiently. Finally, analysis and simulation are provided to verify its feasibility and the ability to ...
