    Fault Reconstruction Based on Sliding Mode Observer for Current Sensors of PMSM (2015)
    Hindawi
    Details
    Publication Date: 2015-11-25
    Description: This paper deals with a method of phase current sensor fault reconstruction for permanent magnet synchronous motor (PMSM) drives. A new state variable is introduced so that an augmented system can be constructed to treat PMSM sensor faults as actuator faults. This method uses the PMSM two-phase stationary reference frame fault model and a sliding mode variable structure observer to reconstruct fault signals. A logic algorithm is built to isolate and identify the faulty sensor for a stator phase current fault after reconstructing the two-phase stationary reference frame fault signals, which allows the phase fault signals to be reconstructed. Simulation results are presented to illustrate the functionality of the theoretical developments.

    Water, Vol. 7, Pages 2422-2434: Effects of Misgurnus anguillicaudatus and Cipangopaludina cathayensis on Pollutant Removal and Microbial Community in Constructed Wetlands (2015)
    MDPI Publishing
    In: Water
    Details
    Publication Date: 2015-05-22
    Description: Aquatic animals play an important role in the energy flow and matter cycling in the wetland ecosystem. However, little is known about their effects on pollutant removal performance and microbial community in constructed wetlands. This work presents an initial attempt to investigate the effects of Misgurnus anguillicaudatus (loach) and Cipangopaludina cathayensis (snail) on nutrient removal performance and microbial community of constructed wetlands (CWs). Compared with a control group, CW microcosms with aquatic animals exhibited better pollutant removal performance. The removal efficiencies of total phosphorus (TP) in the loach group were 13.1% higher than in the control group, and snails increased the ammonium removal most effectively. Moreover, the concentration of total organic carbon (TOC) and TP in sediment significantly reduced with the addition of loaches and snails (p 〈 0.05), whereas the concentration of total nitrogen (TN) showed an obvious increase with the addition of loaches. High-throughput sequencing showed a microbial community structure change. Loaches and snails in wetlands changed the microbial diversity, especially in the Proteobacteria and denitrifying community. Results suggested that benthic aquatic animals might play an important role in CW ecosystems.

    Simulated warm periods of climate over China during the last two millennia: The Sui-Tang warm period versus the Song-Yuan warm period (2015)
    Wiley
    Details
    Publication Date: 2015-02-20
    Description: A 2000-year simulation forced by the external forcings of the last two millennia is carried out with the Community Earth System Model. We compare climate changes over China between the peak Sui-Tang warm period (Sui-TangWP; 650−700 A.D.) and Song-Yuan warm period (Song-YuanWP; 950−1000 A.D.), which were two key culturally, economically and educationally prosperous eras in Chinese history. The simulation indicates warm conditions in both periods, but the warmth is mainly seen in East China in the peak Sui-TangWP, and over the whole of China in the peak Song-YuanWP. The warming in the peak Sui-TangWP is attributed to the localized increase of atmospheric net energy with favorable heat transport, whereas the peak Song-YuanWP results from the increase of global solar radiation. The annual mean precipitation anomalies in the peak Sui-TangWP exhibit a meridional dipole pattern over East China, with enhanced precipitation in the region south of the Yangtze River and decreased precipitation to the north. In the peak Song-YuanWP, the precipitation enhances over most parts of China. The precipitation anomalies are largely attributed to the water vapor transport anomalies associated with monsoon circulation changes. The simulated climate changes are broadly consistent with reconstructions, but the magnitude is greatly underestimated. Based on the simulation and reconstuctions, we suggest that the Sui-TangWP may have been a regional phenomenon in China, while the Song-YuanWP was a reflection of global/hemispheric-scale warm events that took place at the same time.

    Investigating uncertainty in the simulation of the Antarctic ice sheet during the mid-Piacenzian (2016)
    Wiley
    Details
    Publication Date: 2016-01-26
    Description: The mid-Piacenzian (~3Ma) represents the most recent warm period in Earth's history on a geological time scale; it is characterized by a significant rise of global sea level. The simulation of the size and location of the ice sheets and the investigation of the uncertainty in the simulations is potentially helpful for constraining reconstructed sea-level changes. In this study, we focus on the behavior of the Antarctic ice sheet (AIS) in the mid-Piacenzian. We investigate the influence of topography correction, model parameters, climate forcings, and model resolution on the modeled AIS and explore the isolated role of atmospheric and oceanic forcings. Forced by the simulated climate changes with the Norwegian Earth System Model, the Parallel Ice Sheet Model (15 km × 15 km) produces a nearly collapsed West AIS (WAIS) in the mid-Piacenzian, with no significant retreat of the East AIS (EAIS). The role of increased air temperature plays a key role in the mass loss of the mid-Piacenzian AIS, while its role is comparable to the role of ocean warming on the melting of the WAIS. In terms of the range of sea-level changes, the largest source of uncertainty in the modeled AIS is derived from ice sheet model parameters and climate forcings. Although the employed model parameters, topography correction factors and model resolution affect the simulated AIS in the mid-Piacenzian, large-scale deglaciation of the EAIS in our sensitivity experiments may only be possible with additional warming.

    α‐Chapman Scale Height: Longitudinal Variation and Global Modeling (2019)
    Wiley
    Details
    Publication Date: 2019
    Description: Abstract Scale height measures the altitude gradient of the electron density profile and relates with the ionospheric chemistry and dynamics, while its longitudinal variation has not been fully investigated in both statistical analyses and empirical modelings. In this study, eleven‐year electron density profiles from Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultations are collected to retrieve the α‐Chapman scale height (Hm) from the lower topside ionospheric electron density profile (within 200 km altitudes above the peak height of F2 layer (hmF2)) by fitting α‐Chapman function with a constant scale height. The Hm shows evident longitudinal variations at mid latitudes and its zonal structure shows a consistency with that of hmF2 during daytime, which indicates neutral winds change the ionospheric height and shape at the same time. Further, a global modeling of Hm named 2PCAFourier‐Hm is built based on a two‐layer Principle Component Analysis combined with Fourier regression analysis of its coefficients under low and moderated solar activity. Longitudinal variation is considered in the Hm’s modeling, along with the variations of local time, latitude, day of the year, and solar activity. Overall, the model well captures the temporal and spatial variations of Hm with a root‐mean‐square‐error of 2.25 km and a correlation coefficient of 0.97 with respect to the COSMIC observations.

    Sustainability, Vol. 11, Pages 108: A Tourist-Based Model of Authenticity of Heritage Sporting Events: The Case of Naadam (2018)
    MDPI
    Details
    Publication Date: 2018
    Description: As one of the important forms of intangible cultural heritage, heritage sporting events are becoming a potential catalyst of tourism. Commodification of heritage sporting events becomes popular for local authorities to boost economic development and express cultural authenticity, given that authenticity creates genuine performances and moving tourism experiences. However, commodification of heritage is a double-edged sword. It is a dilemma to commercialize a heritage sporting event while keeping its authenticity. Therefore, this study proposes a tourist-based model of authenticity to solve this problem, in which the authenticity of heritage sporting events incorporates “cool” and “hot” factors. The model examines these factors and their impact on tourist satisfaction and loyalty using Naadam as the example. Seven hundred questionnaires were distributed at six sites located from east to west of the Inner Mongolia, China. Factor analysis shows there are two factors in cool and hot authenticity, respectively. Both factors of cool authenticity have direct impacts on hot authenticity, satisfaction, and loyalty. Though both intrapersonal and interpersonal factors of hot authenticity have direct positive impacts on tourist satisfaction, only the former affects loyalty directly. The results show the authenticity of event culture is the most important and effective authentic factor, while authentic auxiliary products—the direct expression of commodification—is indispensable for authenticity. This study is helpful for maintaining authenticity and cultural sustainability of heritage sporting events as a destination tourism attraction, given the fact that commodification and the marketing of heritage sporting events has become popular for heritage destination development.
