In this work, at first the PIFA antenna for the triple band operation has been investigated and studied in detail. Further, the modified PIFA antenna design has been studied for BLE commutations of a wearable device. The proposed antenna was also compared with the meandered dipole antenna as a reference antenna which is widely used for BLE communication due to its compact size. While the reference antenna has a smaller size, it suffers a shift in frequency response when placed on the tissue. On the other hand, the proposed antenna shows little difference whether it is placed on a tissue or in...

This book presents a guide to the optimal power flow and dispatching literature from early 1930s to present. It classifies the methods in some detail according to the optimization techniques used and shows the functional and chronological relationships. It is not a critical review in that it does not asses the various techniques. It is concluded however that there has been a marked progression in the network modeling, optimization and numerical techniques over the years. Today, commercially available OPF algorithm all satisfy the full nonlinear load flow model and a full set of bounds on...
