摘要：In order to improve the super-resolution reconstruction effect of the single image, a novel multiple dictionaries learning via support vector regression(SVR) and improved iterative back-projection(IBP) are *** characterize the image structure, the low-frequency dictionary is constructed from the normalized brightness of low-frequency image patches in a discrete-cosine-transform(DCT) *** determined by Gaussian weighting are added to the input vector to restore more high-frequency information when training the high-frequency image patch dictionary in the space *** post-processing, the improved IBP is employed to reduce regression errors each *** results show that the peak signal-to-noise ratio(PSNR)and structural similarity(SSIM) of the proposed method are enhanced by 1.6%—5.5% and 1.5%—13.1% compared with those of bicubic interpolation, and the proposed method visually outperforms several algorithms.

摘要：Carbohydrates, with broad-spectrum structures and biological functions, are key organic compounds in nature, along with nucleic acids and proteins. As part of our ongoing efforts to develop a new class of pesticides with novel mechanism of action, a series of novel N-glycosyl-l-pyridyl-lH-pyrazole-5-carboxamide was designed and synthesized via the reactions of glycosyl methanamides and pyridyl-pyrazole acid. The compounds were characte- rized by IH NMR and 13C NMR. The bioassay results indicate that some of these compounds exhibit moderate insec- ticidal activities and assessed as potential inhibitors of calcium channels. The modulation of voltage-gated calcium channels by compounds 4a and 5a in the central neurons isolated from the third instar larvae of Spodoptera exigua was studied by whole-cell patch-clamp technique. In addition, compound 5a inhibits the recorded calcium currents reversible on washout. Experimental results also indicate that compound 5a did not release stored calcium from the Endoplasmic Reticulum. The present work demonstrates that N-glycosyl-l-pyridyl-lH-pyrazole-5-carboxamides cannot be used as possible inhibitors of calcium channels for developing novel pesticides.

摘要：客观造化是与书法相关的四要素之一;书法与客观造化的融会主要通过书法家的学习、创作,物化于书法作品之中,也可通过欣赏者对书法作品的欣赏来实现;书法与客观造化的融会肇自汉字与客观造化的融会,主要包括形象、体势、意味、道理四个层面,并以无形的融会为主,使之得到进一步的丰富与拓展。

摘要：书法是民族艺术的瑰宝,是艺术创作的灵魂和源泉。作为艺术设计的一门专业基础课,带有浓郁的东方民族特色,以其独特的艺术魅力和审美元素,特有的浓淡干湿枯的笔墨、结构、章法的造型美,越来越多地成为艺术设计师们广泛应用的一个设计元素。所以,在计算机普及的今天,这种古老的中国传统文化,仍有着不可替代的作用。

摘要：为了协调多电源短期联合调度方案经济性与可靠性之间的关系,需要建立高效、实用的模型,并采用新型优化算法对调度模型进行求解。本文基于最优潮流理论建立多电源短期联合优化调度模型,在目标函数中考虑电力系统的经济性与可靠性指标,在约束条件中考虑电源约束条件和电网约束条件。在计算发电系统可靠性时,采用基于运行状态的瞬时可靠性评估法,有效避免了传统可靠性评估方法在评估风电等波动性较大电源方面的不足。最后以IEEE-30节点系统为例验证本文提出的优化调度模型和算法,结果表明,本文的联合调度策略可提高系统的可靠性指标,降低风电场的弃风量,增加梯级水电与风电的上网电量,保证火电输出功率的平稳性。

摘要：复合材料固化是成型过程中关键步骤之一,涉及到模具设计,成型工艺确定等。本文采用等温DSC分别研究了玻璃纤维/乙烯基酯树脂,碳纤维/乙烯基酯树脂复合材料和乙烯基酯树脂的固化过程。结果表明:玻璃纤维的存在加速了乙烯基酯树脂的固化速度,而碳纤维的存在使得乙烯基酯树脂的固化速度变慢,纤维增强材料的存在提高了树脂的固化度。

摘要：书法是被国际公认的代表中国艺术精神的人类国粹之一,且被列入世界非物质文化遗产,理应受到高等教育特别是艺术学院的珍视。但现实情况看,我国高等教育中艺术学院书法教学还存在不少问题。文中阐述大学艺术院校教育中加强书法教学的重要性和必要性,分析大学艺术教育中书法教学的基本状况及大学艺术学院书法教学的改革对策,同时指出在新媒体时代抓住契机会给书法发展带来一次新的生机。
