Research and Application of Meteorological Response Measures for Civil Engineering and Data Acquisition System

Meteorological conditions have a very important impact on the development of construction projects.In order to assist project site managers to quickly and accurately deal with the engineering risks brought by meteorological conditions,meteorological risk assessment indicators for civil construction are established based on the actual impact of different meteorological conditions on each sub-project of civil engineering.A meteorological intelligent management system is created,and it will select reasonable countermeasures from the integrated existing database and push them to on-site construction managers based on meteorological risk assessment indicators.Through the pre-set construction log module,the managers can give feedback on the application effect of the pushed measures,and achieve the effect of construction data collection,correction and expansion of the existing database.

Analysis of the ITIL Mapping with COBIT over the Business Process Continuity Management

Planning and implementation as well as increased control over the Business Continuity Management （BCM） is a complex task in the company requiring adequate resources. BCM aims to reduce risks and develops plans for restoring business activities if they are interrupted by a disaster. The purpose of the paper is to analyze and describe two standards, Information Technology Infrastructure Library （ITIL） and Control Objectives for Information and Related Technology （COBIT）, especially their mapping for the improved planning and implementation of the BCM as well as the increased control over the BCM activities. COBIT is used more as a management framework, providing management tools, such as control objectives, metrics and maturity models in order to complement the control framework. ITIL includes process steps and tasks because it is more oriented towards IT processes （process framework）, defining the best practice for IT service management. Within this mapping, ITIL processes may be used to achieve and demonstrate compliance with COBIT control objectives for BCM process.

Comparison of Digital Maps: Recognition and Quantitative Measure of Changes

A new methodology of comparing digital raster maps was proposed which allows not only detecting changes in the maps, but also obtaining quantitative measures of the importance of selected differences. Procedure of object interpretation of satellite images and forming of OMT (Object Map of Territory) is described. A list of allowable differences between two OMTs is defined. Two steps technique of quantitative measuring is proposed. At the first stage functions are constructed for calculating local measures of differences in the amount, areas and locations of objects on the map, as well as relations between the objects. In the second stage local measures are used to calculate the integral measure in order to get generalized assessment of difference between maps. The methods for constructing functions which calculate local and integral measures of differences are described. Examples of comparing and measuring the differences between OMTs are provided. Obtained results by utilizing this technique can be used to analyze trends, forecast of development and might be helpful for choosing most efficient scenarios for sustainable spatial planning and land management.

Predicting User Satisfaction of Non-volitional Enterprise Systems: An Example From Telecomunications

The rapid pace of technological change has seen information and communication technologies become the digital backbone of developed nations’ economies and a pre-requisite for global trade. Some enterprise systems are however more than mere facilitators, they provide the bedrock without which organizations could not function;we term these mandatory systems “non-volitional”(NVS). With hyper-growth in demand for connectivity, telecommunications are typical of sectors where NVS shape the fiercely competitive landscape. Among them, Billing & Revenue Management Systems (BRMS) are a form of credit, providers deliver a service and subscribers later pay for that service. As such, they are “business critical”, meaning failures may affect an organization’s ability to conduct its core business. Failures also impact user satisfaction, a key measure of information systems success. However, relatively few studies empirically test this notion;fewer still evaluate it at organizational (rather than individual) level, while there is a dearth of literature investigating non-volitional systems and, to the best of our knowledge, none whatsoever consider ways of predicting user satisfaction for BRMS. According to a renowned and widely cited conceptual model, user satisfaction is influenced by information, system, and service quality respectively. To test this theory for telecoms BRMS, we applied structural equation modelling to investigate which of these dimensions has the most effect. The results indicate that information quality, system quality, service quality, and user satisfaction are all valid measures of BRMS success. Hypothesized relationships between the four success dimensions were significantly substantiated. The study also identified five measures of information quality, four measures of system quality, four measures of service quality, and four measures of user satisfaction. Once the proposed model had been successfully validated, we tested the level of significance among user satisfaction and the three quality dimensions. Findings showed that service quality had the strongest influence on user satisfaction, with information quality second. This is quite different from other applications considered in our literature review which mostly have information quality as having the strongest impact (knowledge management systems apart).

福建省漳州市水稻物候特征对稻田土壤有机碳制图的影响

高精度土壤有机碳制图是研究耕地土壤有机碳时空格局及其影响机制的基础,相关研究结果可为农田“固碳减排”措施的制定提供决策支持。农业管理活动是农田土壤有机碳发生变化的重要影响因子,但基于农业管理活动的土壤有机碳制图却较为少见。基于遥感影像提取的物候参数是农业管理活动的直接反映,在研究农业管理活动对农田土壤有机碳的影响方面有较大应用潜力。基于此,本研究以福建省漳州市水稻田为研究对象,利用随机森林算法,基于5组不同的变量组合(A组:仅自然环境变量;B组:自然环境变量+早稻物候参数:C组:自然环境变量+晚稻物候参数;D组:自然环境变量+早稻物候参数+晚稻物候参数;E组:仅早稻物候参数+晚稻物候参数),分别构建土壤有机碳含量预测模型。通过对比5组模型的预测精度、预测值的空间分布特征和相关影响因子的重要性,分析物候参数对于土壤有机碳制图精度的影响作用,挖掘漳州市水田土壤有机碳制图的主要影响因子,解析对漳州市水田土壤有机碳有重要影响作用的农业管理活动。研究结果表明:物候参数的加入能够降低预测模型的误差和提升模型解释方差的能力;对漳州市水田土壤有机碳影响作用最大的物候参数依次为早稻季的NDVI增长速率(h1)、早稻生长季节开始的时间(a1)与早稻季NDVI下降速率(i1);三个最重要的物候参数与土壤有机碳含量分别呈正相关、负相关和负相关,因此,采取能够促使早稻苗早生快发、加快早稻分蘖速率和减缓早稻衰老速率的水肥管理措施可增加耕地土壤有机碳含量。基于物候参数构建预测模型能有效提高农田土壤有机碳制图精度,基于物候参数的农田土壤有机碳制图研究可为农田管理提供决策支持,此次研究结果可为相关研究提供理论依据。

“数据要素×”赋能城市精细化治理——以环卫责任地图在武汉智慧环卫的应用为例

随着科技的飞速发展,数据要素在赋能城市精细化治理方面的作用愈发明显。海量的数据要素在给城市管理部门带来便利的同时,也暴露出一些新的问题亟待解决。近年来,智慧化环卫信息管理系统已逐步成为城乡环卫部门日常管理的必备工具。智慧环卫平台通常基于公用GIS地图实现各类基础信息落图展示、作业考核、统计分析等功能,但该类地图普遍缺少环卫行业专项的管理要素。加之在实践中,各级城市管理部门普遍缺乏完整准确的基础信息,导致考核基准难以确立权威。如何通过创新技术路径,与权威机构合作开发能够共享公共数据资产,构筑边界更准确、责任更明晰、区域全覆盖的底层地图架构,实现准确权威的考核基准,是数据要素赋能城市精细化治理、深化数智化应用亟需解决的问题。通过武汉市智慧环卫系统开发,探索与勘测设计研究院开展合作,推动双方数据资产合作开发利用,形成环卫责任地图,为业务板块提供准确的考核基准,验证了实践和探索的具体方法和步骤。
