房建工程施工监理全过程及注意事项

施工监理工作对房屋建筑工程的施工和建设起到了非常关键的监督和管理作用,可以有效地在施工过程中将存在的各种影响因素进行管理和排除,促使施工过程顺利进行,还可以保证施工作业的质量和整体进度在可控制的范围内。但是目前监理工作依然还存在一些问题需要进行解决,才能够保证工作的顺利开展。基于此,文章针对房建工程施工监理全过程及注意事项进行了分析和探讨。     

对房屋建筑工程监理现场质量管理的探究

房屋建筑工程的质量与建筑使用者的利益息息相关,因此,保障房屋建筑质量就成为建筑施工单位的主要任务之一.房屋施工涉及到土方、施工主体、混凝土等控制,确保房屋建筑工程质量必须对工程进行严格的监理,监督现场施工情况.目前监理现场质量管理存在的问题主要包括规范性不足、公正性不明显以及缺乏安全管理三点,而提升监理现场质量管理水平的策略包括及时抽样检测、安全监督现场以及控制施工质量三个方面.     

输变电工程项目管理系统的设计与实现

该系统是一个以项目为中心、面向过程的管理系统。围绕“进度、投资、质量、安全”4控制和“合同、信息”两管理的要求，根据各参建单位之间的数据流向，建立相应的工作流程，确定分级管理的内容，在此基础上设立省集团公司、项目建设单位、监理单位和承建单位4个子系统，采取由省集团公司基建管理部门宏观管理，项目建设单位负责组织和具体工程管理，监理单位对工程实施进行监理，承建(施工)单位进行工程施工的3级管理模式，运用集中管理、分工负责、逐级上报和协同工作的管理方式，通过权限控制，工程管理人员根据自己的职责范围和管理权限，对工程项目进行管理，并将工程情况逐级上报并落实上一级管理部门的指示。

含义 资质 标准 信息工程监理三释疑

我国信息化建设的快速发展让信息工程监理逐渐走向前台。“工程监理”一词原本主要用于建筑领域,表示对某个建筑工程进行监督和管理,而其在信息化建设中的应用还刚刚开始。目前,我国一些地区也采用了信息工程监理,在实践中对这种监理模式的确切含义、监理工程师的资质要求、监理所需的标准等问题进行了探讨。监理对象更难判断信息工程监理与其他行业的工程监理一样同属于“工程监理”的范畴,它具有工程监理的共性。这表现在监理依据的一致:依照政府相关部门的法律、法规对工程项目进行监理;监理目标的一致:质量控制、进度控制、投资控制、合…

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.     

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.     

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

Explanation and prediction: an architecture for default and abductive reasoning

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.     

Three Process Perspectives: Organizations, Teams, and People

This paper provides the author's personal views and perspectives on software process improvement. Starting with his first work on technology assessment in IBM over 20 years ago, Watts Humphrey describes the process improvement work he has been directly involved in. This includes the development of the early process assessment methods, the original design of the CMM, and the introduction of the Personal Software Process (PSP)^SM and Team Software Process (TSP){^SM}. In addition to describing the original motivation for this work, the author also reviews many of the problems he and his associates encountered and why they solved them the way they did. He also comments on the outstanding issues and likely directions for future work. Finally, this work has built on the experiences and contributions of many people. Mr. Humphrey only describes work that he was personally involved in and he names many of the key contributors. However, so many people have been involved in this work that a full list of the important participants would be impractical.     

基于复小波噪声方差显著修正的SAR图像去噪

提出了一种基于复小波域统计建模与噪声方差估计显著性修正相结合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像斑点噪声滤波方法。该方法首先通过对数变换将乘性噪声模型转化为加性噪声模型,然后对变换后的图像进行双树复小波变换(Dualtree Complex Wavelet Transform,DCWT),并对复数小波系数的统计分布进行建模。在此先验分布的基础上,通过运用贝叶斯估计方法从含噪系数中恢复原始系数,达到滤除噪声的目的。实验结果表明该方法在去除噪声的同时保留了图像的细节信息,取得了很好的降噪效果。     

How do children do mathematics with LOGO?

Abstract  This paper considers some results of a study designed to investigate the kinds of mathematical activity undertaken by children (aged between 8 and 11) as they learned to program in LOGO. A model of learning modes is proposed, which attempts to describe the ways in which children used and acquired understanding of the programming/mathematical concepts involved. The remainder of the paper is concerned with discussing the validity and limitations of the model, and its implications for further research and curriculum development.
