 As a fast developing country covering a large territory, China is experiencing rapid environmental changes. High concentrations of aerosols with diverse properties are emitted in the region, providing a unique opportunity for understanding the impact of environmental changes on climate. Until very recently, few observational studies were conducted in… (More)
Operational algorithms for retrieval of aerosols from satellite observations are typically created manually based on the domain knowledge. Validation studies, where the retrievals are compared to the available ground-truth data, are periodically performed with the goal of understanding how to further improve the quality of the retrieval algorithms. This… (More)
 Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol products have been used to address aerosol climatic issues in many parts of the world, but their quality has yet to be determined over China. This paper presents a thorough evaluation of aerosol optical depth (AOD) data retrieved from MODIS collections 4 (C004) and 5 (C005) at two AERONET… (More)
An adaptive model reduction method is proposed for linear timeinvariant systems based on the continuous-time rational orthogonal basis (TakenakaMalmquist basis). The method is to find an adaptive approximation in the energy sense by selecting optimal points for the rational orthogonal basis. The stability of the reduced models holds, and the steady-state… (More)
This paper presents a new adaptive algorithm for frequency-domain identification. The algorithm is related to the rational orthogonal system (Takenaka–Malmquist system). This work is based on an adaptive decomposition algorithm previously proposed for decomposing the Hardy space functions, in which a greedy sequence is obtained according to the maximal… (More)
This paper introduces a new adaptive algorithm in system identification. This adaptive algorithm is a variation of greedy algorithm.
This paper presents an adaptive model reduction method. This method is based on the continuous-time rational orthogonal basis (Takenaka-Malmquist basis). By selecting optimal points for the rational orthogonal basis, it is to find a fast approximation in the energy sense. The steady-state values of step responses are kept to be equal, and the stability of… (More)
In this paper, a new method for frequency domain identification of discrete linear time invariant systems is proposed. A new model structure is used to get the solution of coefficients for mixed or unknown noises case. We applied the augmented Lagranian method in the numerical computation. Given examples show the efficiency of the presented method.
In this paper a comparative study is carried out on the CdSe QDs synthesized from water and ethanol. Our purpose is to present an insight understanding on how hydrogen bonds affect particle agglomeration and consequently photoluminescence (PL) behavior of the QDs. In comparison with those from water, the CdSe QDs from ethanol show super PL with high… (More)
