Coal Mine Monitoring Using ARM7 and ZigBee Vaibhav Pandit1, Prof. U. A. Rane2 1M.E.Student, Dept. of Electronics amp; Telecommunication, S.S.G.M.C.E., Shegaon, India 2Dept. of Electronics amp; Telecommunication, S.S.G.M.C.E., Shegaon, India Abstract— This paper presents design and development of underground coal mine monitoring using ARM7 and ZigBee. A sensor node is developed for sensing different environmental parameters of underground mine. The sensor node has feature of wireless communication using ZigBee transreceiver. Thus, sensor node can be deployed in different parts of mine using efficient topologies. All sensed data is digitized by internal ADCs of LPC2148 microcontroller which gives low power platform with fast execution. The system prototype developed has many advantages that makes it convenient to work in harsh environment of underground mine, monitoring concentration of deadly gases in its atmosphere along with temperature and humidity.

外文原文 Introducing the Spring Framework The Spring Framework: a popular open source application framework that addresses many of the issues outlined in this book. This chapter will introduce the basic ideas of Spring and dis-cuss the central “bean factory” lightweight Inversion-of-Control (IoC) container in detail. Spring makes it particularly easy to implement lightweight, yet extensible, J2EE archi-tectures. It provides an out-of-the-box implementation of the fundamental architectural building blocks we recommend. Spring provides a consistent way of structuring your applications, and provides numerous middle tier features that can make J2EE development significantly easier and more flexible than in traditional approaches. The basic motivations for Spring are: To address areas not well served by other frameworks. There are numerous good solutions to specific areas of J2EE infrastructure: web frameworks, persistence solutions, remoting tools, and so on.

Comparing the Predictive Accuracy of Health Risk Appraisal: The Centers for Disease Control Versus Carter Center Program 1. Introduction The health risk appraisal (HRA) has become a popular approach to help people identify the risks associated with personal characteristics (biological, life-style, family history). Risk factors identified from various epidemiologic studies are combined with mortality statistics in order to assess an individuals risk of mortality within the next 10 years. An individuals risk is usually expressed as risk age (or appraised age), which enables one to compare ones own modifiable risk with that of a cohort. Thus the HRA could be a reasonably efficient method for transmitting this mortality risk information to individuals and stimulating them to change in terms of attitudes, beliefs, and life-styles, if so indicated. Although there are numerous variations of the HRA instrument, the majority are adapted from techniques developed by Robbins and Ha

The relationship between mathematics interest and mathematics achievement: mediating roles of self-efficacy and mathematics anxiety The present study In this study, we propose a serial mediation model, based on existing literatures on how mathematics interest may associate with self-efficacy and affect studentrsquo;s mathematics anxiety, and relation to mathematics achievement. This study contributed by exploring the mediating roles of self-efficacy and mathematics anxiety in the effects of mathematics interest on mathematics achievement (Fig. 1). The following research hypotheses will be tested. H1. Mathematics interest, self-efficacy, and mathematics achievement positively correlate with each other, and they all negatively correlate with mathematics anxiety. H2. Self-efficacy mediates the relationship between mathematics interest and mathematics achievement. H3. Self-efficacy and then mathematics anxiety serial mediate the relationship between mathematics inter

英语原文共 13 页， 用于中文命名实体识别的字-字符图卷积网络 唐卓/万博/彦李扬 摘要—最近的研究试图通过修改标准BiLSTM-CRF模型的结构，将单词信息集成到基于字符的中文NER中。他们遵循显式建模正向和反向序列的范例，采用了LSTM变体，该变体将字符和单词都作为每个方向的输入。尽管丰富了表示形式，但是这些模型无法充分利用未来和过去环境之间的交互作用。在本文中，我们提出了一种新颖的字-字符图卷积网络（WC-GCN），该网络使用交叉GCN块同时处理两个方向的字-字符有向无环图（DAG）。为了改善对长距离依赖性的捕获，引入了全局注意GCN块以学习以全局上下文为条件的节点表示。在这两个模块中，与以前的作品不同，在每个作品中，每个单词都附加到其关联字符或被视为LSTM单元之间的快捷方式，单词和字符被等同�

英语原文共 11 页， Winograd-style任务的数据集重叠分析 摘要 Winograd Schema Challenge (WSC)及其派生的变体已经成为常识推理（CSR）的重要基准。在大规模语料库上训练神经语言模型，WSC上的模型性能已经从偶然水平迅速发展到接近人类水平。在本文中，我们分析了在WSC风格的任务中，这些训练语料库和测试实例之间不同程度的重叠所产生的影响。我们发现，大量的测试实例与对最新模型进行（预）训练的语料库有相当大的重叠，并且当我们对重叠最小的实例评估模型时，分类精度会显著下降。基于这些结果，我们开发了KNOWREF-60K数据集，该数据集包含了从web数据中提取的60K多个代词消歧问题。KNOWREF-60K是迄今为止最大的WSC式常识推理语料库，与当前训练前语料库的重叠比例显著降低。 介绍 Winograd模式挑战的最初目的是作为�
