A study on forecasting electricity production and consumption in smart cities and factories

The electrical power sector must undergo a thorough metamorphosis to achieve the ambitious targets in greenhouse gas reduction set forth in the Paris Agreement of 2015. Reducing uncertainty about demand and, in case of renewable electricity generation, supply is important for the determination of spot electricity prices. In this work we propose and evaluate a context-based technique to anticipate the electricity production and consumption in buildings. We focus on a household with photovoltaics and energy storage system. We analyze the efficiency of Markov chains, stride predictors and also their combination into a hybrid predictor in modelling the evolution of electricity production and consumption. All these methods anticipate electric power based on previous values. The main goal is to determine the best method and its optimal configuration which can be integrated into a (possibly hardware-based) intelligent energy management system. The role of such a system is to adjust and synchronize through prediction the electricity consumption and production in order to increase self-consumption, reducing thus the pressure over the power grid. The experiments performed on datasets collected from a real system show that the best evaluated predictor is the Markov chain configured with an electric power history of 100 values, a context of one electric power value and the interval size of 1.     

三种方法的NP识别比较实验研究

利用错误驱动法、支持向量机法和隐马尔可模型三种方法对汉语文本进行名词短语识别,对实验进行比较分析,结果表明SVM与HMM的识别效果总体上要好于错误驱动法,HMM法在封闭测试中优势明显.研究表明错误驱动法应用于解决从语料库中学习转换规则的传统问题;SVM方法适用于解决两类别的分类问题;而HMM方法侧重应用在与线性序列相关的现象上.

New modalities of state power: neoliberal responsibilisation and the work of academy chains

This paper draws on interview data gathered as part of a broader study around issues of equity and schooling. It features the voices of the Executive Director and four Head Teachers from one of England's top performing academy chains, ‘CONNECT’. The notion of neoliberal responsibilisation is drawn on to examine, first, the ways in which Head Teachers describe their work and, second, the chain's expectations of them as CONNECT leaders. Responsibilisation of the self was apparent in Head Teachers' construction of themselves as ideal neoliberal workers – performing and enterprising subjects who readily accept the business principles and results-orientation of their ‘data-driven’ environment. Responsibilising of Head Teachers by the organisation was evident in the rigorous ‘non-negotiable’ standards and accountabilities at CONNECT that they were expected to comply with. These non-negotiables cultivated and rewarded Head Teachers’ entrepreneurial identity of achievement motivation. The paper illustrates how such neoliberal responsibilisation is both a crucial and highly troubling element in the work of academy chains as new modalities of state power.     

互动仪式链视域下大学生劳动获得感培育探索

目前,劳动教育在大学生获得感培养方面仍有可提升之处。该文通过互动仪式链视角“情境”“符号”“情感”的核心要素,分析大学生劳动获得感现状,发现大学生存在身体在场空置、符号动力不足、情感体验式微的困境。上海第二工业大学进行了提升大学生劳动获得感的本土实践,创建中微观情境,打造显性认同的劳动符号,实现情感体验的延续,切实聚焦劳动获得内容、获得环境、获得途径、获得体验和获得共享,实现劳动有所获、有所得,推动大学生劳动获得感提升的良性循环。     

时齐马氏链渐进性双曲方程稳定解存在性分析

双曲方程的稳定解分析方法在现代数学应用中具有广泛的意义。采用时齐马氏链进行双曲方程稳定解存在性分析具有模型匹配度高的优点。构建时齐马氏链的双曲波动方程,设计自组织非光滑时滞的双曲系统,结合时齐马氏链渐进性条件下的Lyapunov-Krasovskii泛函算法,对时齐马氏链渐进性条件临界阈值确定,以有效分析双曲方程的稳定解存在性,提高并行算法处理效率,在一阶非光滑时滞系统中得到方向性时齐马氏链函数的分解特征。研究证明,时齐马氏链渐进性条件下,双曲方程存在稳定性解,解向量在有限时间内收敛。

连锁超市经营中存在的问题及其发展对策

加世纪90年代以来，外资连锁超市纷纷进入中国大陆市场，我国的连锁超市业面临着巨大的挑战0由于我国的连锁超市与外资连锁超市相比还存在着经营理念落后、新兴业态的冲击、盲目扩大的规模风险、经营管理差距等问题。因此，为适应市场变化的要求，我国的连锁超市在发展中应创新超市经营理念；整合超市业态。构建超市发展平台；谨慎扩张，追求规模效益；同时深化超市经营管理，以此来促进连锁超市的发展。
