Dispersion-engineered wideband low-profile metasurface antennas Review Articles

Wei E. I. LIU, Zhi Ning CHEN, Xianming QING

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 1,   Pages 27-38 doi: 10.1631/FITEE.1900473

Abstract: A metasurface (MTS) can be characterized in terms of dispersion properties of guided waves and surface waves. By engineering the rich dispersion relations, setting particular boundary conditions, and selecting proper excitation schemes, multiple adjacent resonance modes can be excited to realize the wideband operation of low-profile MTS antennas. We introduce the op-erating principles of typical dispersion-engineered MTS antennas, and review the recent progress in dispersion-engineered MTS antenna technology. The miniaturization, circular polarization, beam-scanning, and other functionalities of MTS antennas are discussed. The recent development of MTS antennas has not only provided promising solutions to the wideband and low-profile antenna design but also proven great potential of MTS in developing innovative antenna technologies.

Do right PLS and do PLS right: A critical review of the application of PLS-SEM in construction management

Ningshuang ZENG, Yan LIU, Pan GONG, Marcel HERTOGH, Markus KÖNIG

Frontiers of Engineering Management 2021, Volume 8, Issue 3,   Pages 356-369 doi: 10.1007/s42524-021-0153-5

Abstract: Partial least squares structural equation modeling (PLS-SEM) is a modern multivariate analysis technique with a demonstrated ability to estimate theoretically established cause-effect relationship models. This technique has been increasingly adopted in construction management research over the last two decades. Accordingly, a critical review of studies adopting PLS-SEM appears to be a timely and valuable endeavor. This paper offers a critical review of 139 articles that applied PLS-SEM from 2002 to 2019. Results show that the misuse of PLS-SEM can be avoided. Critical issues related to the application of PLS-SEM, research design, model development, and model evaluation are discussed in detail. This paper is the first to highlight the use and misuse of PLS-SEM in the construction management area and provides recommendations to facilitate the future application of PLS-SEM in this field.

Industrial water treatment and industrial marine outfalls: Achieving the right balance

Adrian W. K. Law,Chunyan Tang

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 4,   Pages 472-479 doi: 10.1007/s11705-016-1592-0

Abstract: Industrial water treatment and industrial marine outfalls both function together to reduce the pollutant concentrations in the effluent and mitigate the potential impact on the environment. The former uses environmental treatment technology with energy and material cost considerations, while the latter utilizes the natural assimilation potential of the coastal water environment achievable at the outfall location. Because of their synergistic nature, marine outfalls are now commonly used for the disposal of partially treated domestic and industrial effluents in many coastal cities around the world, with many successful examples of low and acceptable risks to the environment. The objective of this paper is to review their balance from both environmental and economic considerations. We also discuss the end-of-the-pipe and mixing zone approaches for industrial effluents, and give some recommendations particularly for developing countries. Finally, we emphasize that a compulsory and vigorous monitoring program is essential regardless of how the balance is achieved.
