针对煤矿应急救援辅助决策系统中应急预案应用不足、应用效率低及系统生成的救援方案可执行性欠佳等问题,提出了一种基于应急预案的煤矿应急救援辅助决策系统设计方法。该方法采用基于大语言模型的信息抽取技术,从应急预案中提炼出关键任务要素,如任务名称、触发条件、执行部门和任务内容等,形成元任务,并构建根据事故类型和级别对元任务进行分类存储的元任务库;发生煤矿安全事故时,运用基于SBERT模型的语义匹配技术,根据现场收集的信息进行事故分类分级,并从元任务库中筛选出与当前应急需求相符合的元任务集;为提高任务的可执行性,将元任务与实时采集的现场数据结合,通过指令模板构建具体的行动指令,并利用任务规划技术对指令的优先级进行优化和调整,生成切实可行的现场救援方案。基于应急预案的煤矿应急救援辅助决策系统充分利用了应急预案的规范化内容,形成了与现场信息紧密结合、资源优化的救援方案,进一步提高了救援决策的准确性、科学性和智能化水平。

基于DCSP的煤矿应急救援资源调配方法

在大规模群体突发事件发生后,如何实时及有效地调配资源,是保障应急救援快速实施的关键。以煤矿应急救援为背景,探讨合适的资源调配方法。分布式约束满足问题(D(',SP-Distributed Constraint Satisfaction Problem)擅于表示及求解分布式环境下以协作性为主的问题,是一种解决具有信息分布、需求随环境动态变化等特点的资源调配问题的有效方法,而煤矿应急救援问题正好具有这样的特征。因此,采用DCSP方法来解决煤矿应急救援中的资源调配问题,抽取并构建了煤矿应急救援资源调配的模型,讨论了Agent模型和约束模型的定义,改进了MAWS(MAWS-Multiple Asynchronous Weak-commitment Search)算法。经实验验证,采用DCSP方法可在事故发生后的较短时间内做出有效的资源调配决策,减少资源送达到事故点的时间,为应急救援争取了大量救援时间,从而减少了煤矿事故发生后的人员伤亡和经济损失。

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.

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。
