摘要

1. 导论:信息技术时代的运河网管理。随着传感器的小型化及其成本的降低,建筑基础设施和环境的仪器仪表模式已经进行了几年,导致了许多成功的,有时是壮观的实现,例如几年前的金门无线传感器仪器仪表。通信、控制和传感在包括多媒体平台在内的众多平台上的融合,使工程师能够用信息层增强物理基础设施系统,能够进行实时监测,在健康监测领域取得了特别成功。这种模式已经达到了成熟的程度,这是由许多可用于监视已构建的基础设施的技术的出现所揭示的。监控和数据采集(SCADA)系统是这种基础设施的一个完美例子,它集成了传感、通信和控制。在灌溉网管理方面,这项技术对控制这类系统的影响有可能大大提高作业效率。在大型基础设施系统中“闭环”的想法并不新鲜,事实上,在美国的河口环境等水管理系统中,州当局已经讨论了十多年,例如在加利福尼亚州。在越南,农民已经在潮汐时间尺度上操作闸门,以适当地管理水稻和虾的灌溉。实现“闭环”的“最后一英里”(至少在河口环境的情况下)是实时使用传感器数据来整合直接干预反馈回路的系统的精确水动力特征的能力。2. 的贡献。这期《网络与异质媒体》特刊汇集了与2008年10月2日至4日在意大利Maiori举办的“灌溉渠道及相关问题”研讨会相关的文章。研讨会的专家包括传感器硬件制造、估计和控制、流体动力学建模和控制以及偏微分方程优化等领域的专家。研讨会的目标是在考虑灌溉应用的情况下,在这些不同领域之间进行交叉施肥。本期《网络与异质媒体》特刊包括一些演讲者关于他们各自专业领域的文章。完整的名单按字母顺序排列如下:

Open problems and research perspectives for irrigation channels
1. Introduction: Management of canal networks at the age of information technology. With the miniaturization of sensors and their decreasing costs, the paradigm of instrumentation of the built infrastructure and the environment has now been underway for several years, leading to numerous successful and sometimes spectacular realizations such as the instrumentation of the Golden Gate with wireless sensors a few years ago. The convergence of communication, control and sensing on numerous platforms including multi-media platforms has enabled engineers to augment physical infrastructure systems with an information layer, capable of realtime monitoring, with particular success in the health monitoring community. This paradigm has reached a level of maturity, revealed by the emergence of numerous technologies usable to monitor the built infrastructure. Supervisory Control And Data Acquisition (SCADA) systems are a perfect example of such infrastructure, which integrate sensing, communication and control. In the context of management of irrigation networks, the impact of this technology on the control of such systems has the potential of significantly improving efficiency of operations. The idea of “closing the loop” in large scale infrastructure systems is not new, in fact in water management systems such as estuarine environments in the US, State authorities have talked about it for now more than a decade, for example in California. In Vietnam, farmers already operate gates on tidal timescales to manage irrigation properly for rice and shrimps.

期刊介绍: NHM offers a strong combination of three features: Interdisciplinary character, specific focus, and deep mathematical content. Also, the journal aims to create a link between the discrete and the continuous communities, which distinguishes it from other journals with strong PDE orientation. NHM publishes original contributions of high quality in networks, heterogeneous media and related fields. NHM is thus devoted to research work on complex media arising in mathematical, physical, engineering, socio-economical and bio-medical problems.
