Load frequency control of power systems with large scale of wind power integrated based on particle swarm algorithm Abstract: An interconnected power system with large scale of wind power integration is taken as our research object. In order to keep the stability of frequency, a PSO based load frequency controller is proposed. According to the amount of area control error (ACE), traditional load frequency controller is to adjust the output of units in order to make ACE approach to zero. Then output from all generators is matched to the demand from load. Output from wind units is taken as a negative load and an equivalent load is formed. Intelligent PSO is introduced into traditional load frequency controller and is expected to improve the control performance. The simulation based on the model, which is constructed on Matlab/Simulink platform demonstrates that, for the new design controller, its performance index whether frequency error of interconnected network or exchange flow

Firm Ramp;D, Processing Trade and Input Trade Liberalisation: Evidence from Chinese Firms HE nexus between firm innovation and trade liberalisation is an important research sub- ject in the empirical trade literature, as firm innovation is an important channel for firms T to realise productivity gains from trade. Some work in this area has focused on how output trade liberalisation affects firm research and development (Ramp;D) inputs (Iacovone et al., 2013; Bloom et al., forthcoming). Since tariff reductions usually happen bilaterally, other research has concentrated on how cuts in foreign tariffs boost firm Ramp;D activity (Aw et al., 2007, 2011; Lileeva and Trefler, 2010; Bustos, 2011). Some researchers have been paying more attention to the role of imported intermediate inputs by exploring how input trade liber- alisation affects firm Ramp;D behaviour (Kim and Nelson, 2000; Griffith et al., 2004; Hu et al., 2005; Goldberg et al., 2010). The present paper examines

The logistics distribution modes have always been the bottleneck factors that restrict the development of fresh agricultural productsrsquo; e-commerce. Based on the studying of traditional logistics distribution modes, this paper points out five problems of how to create the e-commerce logistics distribution system. This thesis analyses the e-commerce logistics distribution modes of fresh agricultural products and the business process; summarizes the advantages and problems of the e-commerce logist

英语原文共 6 页， 标题：真正的荧光激发依赖性碳点及其在多色细胞成像和多维传感中的应用 正文： 碳点（CDs）是碳基荧光（FL）纳米材料中最重要的一类，近年来受到了广泛的关注。由于其优异的光学性能(例如高光稳定性、双光性和荧光激发依赖性），良好的生物相容性和易于制备的特性，CDs已展示出许多潜在的应用，如传感、生物医学、催化和光电子器件。在CDs优异的光学特性中，发射依赖于激发的光学性能非常有趣，但遗憾的是，这种独特的光谱特性的应用仍然很少被开发。这可能是由于以下两个原因:i)虽然许多报告都介绍了激发依赖性CDs，但其荧光发射波长的变化往往伴随着强度的强烈降低，而这种光学性质不能真正被称为激发依赖性；ii)理解和设计CDs的荧光激发相关发射非常具有挑战性，因此，很难根据需要合理�

英语原文共 9 页， 材料视野 概念性的见解 用于三重态三重态湮没上转换的传统发射极只能显示一个颜色 UC 发射，因为它只包含一个发色团为了获得不同颜色的 TTA-UC 发射，需要激发不同的发射极-敏化剂对这就限制了 TTA-UC 的应用多色成像、多路检测、信息存储等领域等。在这里，我们已经成功地开发了两个 TTA 发射器的颜色可调的 TTA- UC这两个发射体都是蒽二聚体，它们的结构和性质都与蒽二聚体有关从扭曲的分子内电荷转移态(TICT)发出荧光。由于 TICT 的发射波长对溶剂的极性很敏感，因此，TTA-UC 发射的颜色可以调整。基于这种发射器，具有只有一个发射极敏化器对和一个波长激发，不同的 TTA-UC在不同的溶剂中可以实现发射。假设大量的分子用不同的结构可以形成 TICT 状态，与各子单元之间的相互作用可以通过分子结构来调�

The first part describes the timeline of the inclusion of the mobility of people and goods in French public policies. It presents the gap between passenger and goods mobility relating to the growth of skills and knowledge on the topic, the rise of investigation and simulation methodologies, and the development of new organisations and management tools. In the second part, this comparison serves as a guide to measure the progress needed to help cities in terms of public policy. The third part proposes an appro
