Download or read book Powerflux I written by E. A. Lewis and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple integral formulation is given for the radio wave power propagating between the curved earth and the ionosphere for the case of low frequency transmitters on the surface of the earth. By making assumptions about the vertical field profiles, the field strengths at arbitrary distances and altitudes can be estimated. Field strength versus distance predictions are compared with published mode and wave-hop calculations and with experimental data.

Book Synopsis Advanced Technologies for Planning and Operation of Prosumer Energy Systems, volume III by : Bin Zhou
Download or read book Advanced Technologies for Planning and Operation of Prosumer Energy Systems, volume III written by Bin Zhou and published by Frontiers Media SA. This book was released on 2024-07-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prosumers, such as energy storage, smart home, and microgrids, are the consumers who also produce and share surplus energy with other users. With capabilities of flexibly managing the generation, storage and consumption of energy in a simultaneous manner, prosumers can help improve the operation efficiency of smart grid. Due to the rapid expansion of prosumer clusters, the planning and operation issues of prosumer energy systems have been increasingly raised. Aspects including energy infrastructure design, energy management, system stability, etc., are urgently required to be addressed while taking full advantage of prosumers' capabilities. However, up to date, the research on prosumers has not drawn sufficient attention. This proposal presents the need to introduce a Research Topic on prosumer energy systems in Frontiers in Energy Research. We believe this Research Topic can promote the research on advanced planning and operation technologies of prosumer energy systems and contribute to the carbon neutrality for a sustainable society.

Book Synopsis Direct Measurement of the Hyperfine Structure Interval of Positronium Using High-Power Millimeter Wave Technology by : Akira Miyazaki
Download or read book Direct Measurement of the Hyperfine Structure Interval of Positronium Using High-Power Millimeter Wave Technology written by Akira Miyazaki and published by Springer. This book was released on 2015-06-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the author develops new high-power millimeter wave techniques for measuring the hyperfine structure of positronium (Ps-HFS) directly for the first time in the world. Indirect measurement of Ps-HFS in the literature might have systematic uncertainties related to the use of a static magnetic field. Development of the millimeter wave devices supports the precise determination of Ps-HFS by directly measuring the Breit-Wigner resonant transition from o-Ps to p-Ps without the magnetic field. At the same time, the width of the measured Breit-Wigner resonance directly provides the lifetime of p-Ps. This measurement is the first precise spectroscopic experiment involving the magnetic dipole transition and high-power millimeter waves. The development of a gyrotron and a Fabry-Pérot cavity is described as providing an effective power of over 20 kW, which is required to cause the direct transition from o-Ps to p-Ps. Those values measured by the newly developed millimeter wave device pave the way for examining the discrepancy observed between conventional indirect experiments on Ps-HFS and the theoretical predictions of Quantum Electrodynamics.
