摘要：
A solar energy and high temperature proton exchange membrane fuel cell (PEMFC)-based micro-combined cooling, heating and power (CCHP) system (named system I) is proposed in this work. This system mainly consists of a PEMFC subsystem, an organic Rankine cycle (ORC) subsystem and a vapor compression cycle (VCC) subsystem. System I would reduce to a high temperature PEMFC-based CCHP system (named system II) if there was no solar energy. With the technical performance analysis models developed, the effects of the current density, operating temperature, solar radiation intensity and ambient temperature on the thermal, economic and environmental performances of the systems are theoretically analyzed. The results show that the current density and solar radiation intensity are the main impact factors that can significantly affect the thermal, economic and environmental performances, while the operating temperature and ambient temperature only have remarkable influences on the thermal performance. The coefficient of performance (COP) of system II is approximately 1.19 in summer and 1.42 in winter, which is always higher than that of system I under the same working conditions. The exergy efficiency of system I and system II are approximately 49.7% and 47.4%, respectively. The primary energy saving rates (PESRs) of system I and system II are 64.9% and 31.8% in summer, and 60.0% and 36.2% in winter, respectively. The payback periods of system I and system II are 9.6 yr and 6.0 yr without government subsidy, respectively. Compared with system II, the pollutant emission reduction rates (ERRs) of system I can be increased by approximately 8.4%–23.5% with the addition of solar energy, which indicates that the development and utilization of clean and renewable energy such as solar energy can significantly reduce pollutant emissions.

摘要：
Sparse representation has recently been extensively studied in the field of image restoration. Many sparsity-based approaches enforce sparse coding on patches with certain constraints. However, extracting structural information is a challenging task in the field image restoration. Motivated by the fact that structured sparse representation (SSR) method can capture the inner characteristics of image structures, which helps in finding sparse representations of nonlinear features or patterns, we propose the SSR approach for image restoration. Specifically, a generalized model is developed using structured restraint, namely, the group l(2,1)-norm of the coefficient matrix is introduced in the traditional sparse representation with respect to minimizing the differences within classes and maximizing the differences between classes for sparse representation, and its applications with image restoration are also explored. The sparse coefficients of SSR are obtained through iterative optimization approach. Experimental results have shown that the proposed SSR technique can significantly deliver the reconstructed images with high quality, which manifest the effectiveness of our approach in both peak signal-to-noise ratio performance and visual perception.

摘要：
We investigated the Hall-Petch relations in Al-ZnO composites with different matrix grain size (D) relative to interparticle spacing (L). For samples with D>L, it was found that grain refinement as described by Hall-Petch relation and particle strengthening by Orowan mechanism both significantly contribute to the strengthening of the composites. For samples with D <= L, variation of microhardness with grain size was found to follow a good Hall-Petch relation with an enhanced Hall-Petch slope. Our study indicates the different coupling of strengthening mechanisms in metal matrix composites with different microstructure length scales. (C) 2018 Acta Materialia Inc. Published by Elsevier Ltd.

摘要：
TiO2-loaded Ti3C2 with small interlayer spacing [TiO2/Ti3C2(SIS)] was successfully synthesized through hydrothermal treatment and subsequent calcination under argon atmosphere. The phase composition, morphology and photophysical properties of Ti3C2, TiO2 and TiO2/Ti3C2(SIS) were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FSEM), transmission electron microscopy (TEM), UV–Vis spectrophotometry and fluorescence spectrophotometer, respectively. Furthermore, the photocatalytic activities of Ti3C2, TiO2 and TiO2/Ti3C2(SIS) were measured through monitoring photodegradation of methylene blue (MB) under ultraviolet (UV) light irradiation. The results showed that TiO2/Ti3C2(SIS) had an interfacial heterojunction between TiO2 and Ti3C2 with small interlayer spacing, leading to obviously improved optical absorbability and light quantum efficiency. Furthermore, the results of photocatalytic experiment indicated that TiO2/Ti3C2(SIS) exhibited significantly improved photocataytic activity compared with Ti3C2 and TiO2.

Joint-joint adjacent matrix;Improved hamming number matrix;Isomorphism identification;Kinematic chains;Multiple joints
摘要：
During the process of kinematic structure enumeration using graph theory, isomorphism identification of graphs is an important and complicated problem. In this paper, an improved hamming number method (IHNM) was proposed to detect isomorphism for kinematic chain with multiple joints. Firstly, it is difficult to deal with multiple joints in mechanism analysis and synthesis, so the joint-joint matrix is used to describe the kinematic chain. The matrix can uniquely represent the kinematic chain. Then, the improved Hamming matrix is obtained by the improved hamming number method. The joint Hamming number, chain Hamming number and joint Hamming string were introduced, which can determine whether the kinematic chain is isomorphic or not. Eventually, the examples demonstrate that this new method can be accurately and effectively performed.
