Opis:: Bio-mimetic underwater robotics is an emerging area of research, which has the potential to substitute the conventional energy inefficient mode of underwater propulsion using thrusters. In this paper, the mathematical modelling of the undulating fin is done and the effect of various parameters of the mechanism design on the available workspace is studied. The mathematical beauty is revealed, for the curves representing the mechanical constraint and the family of undulating waves. The feasibility of a wave to be generated by the mechanism was analyzed.

Opis:: Median Paired Fin Propulsion used by fishes like knife fish, has the potential to replace current energy inefficient underwater propulsion systems. This paper quantizes the efficiency of a fin mechanism based on its ability to incorporate a large number of undulations. Characteristic ellipses of a mechanism were defined, based on which two algorithms were defined to measure the capabilities of the mechanism. The available workspace of the mechanism was optimized to accommodate the undulation requirements of the robot based on the formulations. Further, the distortion effect on the waveform was identified and the optimization was redefined to obviate its possibility while in operation.

Opis:: The high demand for network coverage in an indoor setting brought about the acceptance of femtocell technology as a solution using the backhaul connectivity in the existing network. The quality of signal, voice calling, Internet, security and data are improved through the use femtocell at the indoor environment. Here the service provider attempts to reduce their operation cost by presenting self-organizing mechanisms for optimization of the network. The remarkable part is that, femtocells improves coverage, enhances the data rate at the indoor environment. Therefore, the challenges of the femtocell also known as interference deteriorates the capacity and quality performance of the whole cellular network. In this paper we simulate the bit error rate against signal behaviour at the indoor environment and we also simulate the transmitting power over signal for both macrocells and femtocells. We focus on the transmitting power that might cause interference within the cellular network.
