This paper presents a linear generator used for energy harvesting system equipped in footwear, which scavenges power from back-and-forth motion during walk. Structure of the electric machine is studied, and sizing optimization by finite element analysis (FEA) is detailed. A prototype has been built, validating that the simulated and test results have a good agreement.
The searching mechanism in traditional unstructured P2P networks often consumes a large amount of network resources. Furthermore, queries for rare objects do not receive the desired number of results or even fail, for the object popularitypsilas imbalanced distribution. To deal with these problems, we propose a novel search algorithm: ERAntBudget, which is based on Gnutella protocol and adopts the...
This paper aims at optimal analysis and design of a three-phase line-start PMSM with simple structure, low cost and good performance. A prototype with 4 magnet poles is designed and manufactured. Simulation and experimental results are approximately the same and the prototype essentially satisfies the design request. Moreover, measures are taken to further optimize the design.
