微机型无线水位遥测装置设计     

洪翠  杨耿杰  郭谋发 《闽江学院学报》2007,28(5):72-75

设计了一种基于AT89S52单片微机及数传模块C11的实时水位遥测装置.该装置采用投入式压力传感器测量水位,以单片机为控制核心,利用C11无线数传模块实现信息的远距离无线传输,并在数据传输时应用差错控制技术进行CRC校验,进一步提高数据传输的可靠性.通过无线数传模块与单片机的配合,直线传输距离可达3km.无线式的数据传输更适用于那些由于地域等条件限制无法实现有线数据传输的场合.  相似文献   

Mini-research Experience in Simple Linear Regression     

Paul Isihara  Elisabeth Congdon  Terry Perciante 《PRIMUS》2018,28(7):699-716

Within the undergraduate mathematics curriculum, the topic of simple least-squares linear regression is often first encountered in multi-variable calculus where the line of best fit is obtained by using partial derivatives to find the slope and y-intercept of the line that minimizes the residual sum of squares. A markedly different approach from linear algebra, which could also be introduced in multi-variable calculus, obtains the regression line by vector projection. The latter viewpoint offers elegant proof of the equation relating the total, explained and unexplained variations. Consideration of data with the same regression line and correlation opens the door for a “mini-research experience” (MRE). A sequel MRE gives rise to an open Research Experience for Undergraduates topic to analyze reflection sequences and a fundamental connection between complex analysis and regression analysis. A few general guidelines and basic goals for MREs are included for those whose main interest is in undergraduate research.  相似文献

Seeing Library Data: A Prototype Data Visualization Application for Librarians     

Mark Eaton 《Journal of Web Librarianship》2017,11(1):69-78

Visualizations can add value to raw library data. Tools that programmatically make such visualizations interactive can further increase the value of these data by giving librarians visual tools to analyze their datasets. To demonstrate these benefits, Kingsborough Community College Library built SeeCollections (http://b7jl.org/seecollections), a Web application that visualizes the libraries’ collections of books and e-books. This article discusses the how SeeCollections gathers data from Kingsborough's discovery layer API (Application Programming Interface) and transforms these data to create visualizations for the Web. SeeCollections is a lightweight, proof-of-concept data application based on a vendor API. API data are often accessible in academic libraries but are frequently underutilized. SeeCollections was built to demonstrate the immediate value of these API data sources to Kingsborough librarians by providing a visual interface to discovery layer data. Keeping in mind the broader literature on data visualization, this article will explore how SeeCollections was built.  相似文献   

Guide on the Side and LibWizard Tutorials Side-By-Side: How Do the Two Platforms for Split-Screen Online Tutorials Compare?     

Graham Sherriff 《Journal of Web Librarianship》2017,11(2):124-142

Split-screen tutorials are an appealing and effective way for libraries to create online learning objects where learners interact with real-time Web content. Many libraries are using the University of Arizona's award-winning, open source platform, Guide on the Side. In 2016, Springshare released a proprietary alternative, LibWizard Tutorials. This article reviews the advantages and limitations of this kind of tutorial. It also examines the differences between each platform's distinctive characteristics. These platforms create similar split-screen tutorials, but have differences that affect diverse aspects of installation, administration, authoring and editing, student learning, data management, and accessibility. Libraries now have the opportunity to consider and compare alternative platforms, and decide which one is best suited to their needs, priorities, and resources.  相似文献   

Linked Data Metadata for Digital Clothing Collections     

Maura Valentino 《Journal of Web Librarianship》2017,11(3-4):231-240

ABSTRACT

The historical clothing collections held by academic and other institutions serve as an important resource for scholars in fields ranging from fashion design to sociology. While metadata schemes have been created for individual clothing collections, no standard metadata scheme for clothing had been developed. This case study describes the creation of a linked data metadata scheme for clothing designed for the Oregon State University's College of Business Design Programs' Historical and Cultural Textile and Apparel Collection housed within the ScholarsArchive digital repository. In addition, the scheme can be used as a standard clothing metadata scheme which may be implemented by other organizations, or extended as needed.  相似文献   

深度学习及其对图书情报学的启示          下载免费PDF全文

刘忠宝  赵文娟  贾君枝 《情报工程》2017,3(4):062-070

深度学习是一种新颖的机器学习方法,它已经在图像识别、语音识别、信息检索等诸多领域广泛应用并取得了巨大成功。然而,笔者参阅了近年来国内主流的情报学文献,并未发现有关深度学习的研究成果。因此,本文旨在图书情报领域引入深度学习技术,重点探讨深度学习的基本理论、应用、下一步研究重点以及对情报学的启示等问题,以期为解决图书情报学研究面临的诸多问题提供重要参考。  相似文献   

论回复时限存在的不足及应对措施--关于维护学术期刊作者权利的思考     

任辉 《荆门职业技术学院学报》2004,19(2):87-90

稿约规则中关于回复时限的条款在某些方面存在着不足，在实际操作中易造成作者合法权利的损害。因此，修改回复时限、理顺出版者与作者间的权利和义务关系十分必要。解决这个问题，可从导致审稿时间过长的“瓶颈”——审稿过程入手，做到工作规范，审稿高效，退稿及时。  相似文献
