随着计算机技术、网络技术的高速发展,及其在电子测量技术与仪器上的应用,新的测试理论、新的测试方法不断出现。网络化测量技术与具备网络功能的新型仪器应运而生,网络技术与虚拟仪器技术的结合产生了网络化虚拟仪器。从而突破了传统虚拟仪器的三大功能模块(数据采集、数据分析处理、数据显示)都集中在单一计算机上的限制,而是将不同的功能模块分解到不同的计算机上,利用网络将各个模块灵活的连接起来,使测量仪器、测量数据在网络内得以共享。本文利用NI公司的虚拟仪器软件开发平台LabVIEW,对组建远程测试系统的原理进行了论述。通过设计并实现远程测控系统,可以在分布很广的作业地域之间实现自动数据采集、传送、分析处理。从而提高工作的安全性和效率。 相似文献

The cost of poor data quality has been measured in the billions of dollars annually. However, deriving coherent data cleansing strategies to improve data quality is challenging because it is often difficult to justify the financial and human capital cost involved in cleaning data. But those who have planned and designed an effective approach to cleaning data report significant benefits. Although extant literature has extensively focused on data quality issues, little attention has been directed toward providing decision-making techniques that help practitioners determine the cost and benefits of adopting data-cleansing approaches. This study advances an approach that illustrates how discrete-event simulation can be used as a decision tool for making data-cleansing decisions, by understanding the interactions among the firms' resources and performance outcomes. To our knowledge, this is one of the first studies to apply discrete-event simulation for evaluating data-cleansing approaches. The article contributes to an understanding of how various organizational resources interact within, and between, two data-cleansing approaches to drive performance outcomes. Simulation approaches such as the one examined here reveal how the complexity of interactions among such factors can produce results that are difficult to anticipate using other approaches. 相似文献

We introduce an exploratory technique that is used to visualize higher order geometries in an easily recognizable two-dimensional representation: parallel coordinate systems. In this research, parallel coordinate systems visual analysis is used to assess competitive pricing behavior. Results show that this simple exploratory technique identified the same main and cross-elasticities identified by an MCI model. This research illustrates the value and simplicity of adding parallel coordinate systems visual analysis to the manager's exploratory analysis tool kit. Implications are discussed. 相似文献

在数据流动问题上,出于维护本国网络空间安全的考虑,俄罗斯制定了世界上最为严密的数据流动限制性政策。在对俄罗斯出台的与贸易相关的数据流动限制措施类别和相关立法进行梳理的基础上,对其形成原因进行了分析。俄罗斯的数据流动限制措施具有3个典型特征:一是数据输出规则针对"白名单"和"黑名单"对象做出鲜明区分;二是设置严密的互联网准入和监管措施;三是实施严格甚至激进的数据本地化政策。最后根据俄罗斯的相关实践给出了对中国实施数据流动管理的相关政策建议:推进跨境数据流动限制分类管理,减少不必要的数据流动限制;保持网络空间自主可控,非敏感领域适当放宽互联网准入和监管机制;充分发挥中国互联网产业优势,降低数据本地化带来的额外成本。 相似文献

Data analytics is an integral part of planning and decision making in business. Priorities have shifted to hiring skilled employees to support a company’s analytics requirements. The authors discuss the background of big data and data analytics, demand for trained professionals, and information on the development of a data analytics curriculum. Curriculum design models are explored and emphasis placed on university curriculum redesign. This is a perspective piece that also addresses interdisciplinary collaboration, accreditation, and related challenges. 相似文献

We explore the availability and use of data (primary and secondary) in the field of business ethics research. Specifically,
we examine an international sample of doctoral dissertations since 1998, categorizing research topics, data collection, and
availability of data. Findings suggest that use of only primary data pervades the discipline, despite strong methodological
reasons to augment business ethics research with secondary data. 相似文献

Log-linear procedures have been recommended for analyzing data that are in the form of counts or frequencies (Iacobucci and McGill 1990). In its current form, the recommended procedure does not deal with multiple response data (i.e., more than one thought per response category). The paper proposes analytical modifications that researchers need to consider when fitting models with this type of data. The problems and recommended modifications are illustrated with two distinct data sets. The first involves consumers' attribution responses to negative word-of-mouth communication about a brand whereas the second pertains to consumers' cognitive responses toward an advertisement. Results in each case indicate that researchers may generate erroneous conclusions about the significance of estimated parameters if the recommendations are ignored. 相似文献
