气象科技创新业务贡献评价标准研究

科技创新重在应用,重在产生效果。对于气象部门而言,创新的效果主要体现在气象业务能力和水平的提升上,然而如何判断科技创新是否对业务产生了贡献,或科技创新对业务产生的贡献大小,需要建立一个具备可比性的、不以评价人的主观意志为转移的客观标准来衡量。为此本研究设计了一个叫做“气象科技创新业务贡献度”的评价指标,试图通过“气象科技创新业务贡献指数”的客观计算,来建立一套客观评价和衡量气象科技创新业务贡献大小的评价标准,供评价项目、单位、区域或部门气象科技创新业务贡献大小时使用。该指标设计的特点是,以突破重大气象业务核心技术为重点,以满足气象业务服务质量和效率提高为指向,形成用于测量气象科技创新业务贡献的定量测量模型,以此为基础,可以开发出满足气象科技创新业务贡献评价需求的、供全国统一使用的气象科技创新业务贡献评价标准。

Removal characteristics of anionic metals by micellar-enhanced ultrafiltration

Surfactant-based separation of Fe(CN)(6)(3-) and CrO(4)(2-) using regenerated cellulose membrane was studied in order to assess the potential of micellar-enhanced ultrafiltration for the remediation of wastewater or groundwater polluted with ferriccyanide and chromate. In the ferriccyanide/octadecylamine acetate (ODA) and chromate/ODA systems, removal of ferriccyanide increased from 73 to 92% and to 98%, and that of chromate from 64 to 97% and to >99.9% as the molar ratio of ODA to ferriccyanide and to chromate increased from 1 to 2 and to 3, respectively. In the ferriccyanide/chromate/ODA system, while the removal of ferriccyanide increased from 62 to 72% and to 93%, the removal of chromate from 20 to 38% and to 68% as the molar ratio of ferriccyanide:chromate:ODA increased from 1:1:1 to 1:1:2 and to 1:1:4, respectively. With the molar ratio of 1:1:6, the removal was >99.9 and 98% for chromate and ferriccyanide, respectively. Ferriccyanide ions were more easily bound to ODA micelles because the binding power of ferriccyanide was greater than that of chromate.     

Identification of Failure Mechanisms to Enhance Prognostic Outcomes

Predicting the reliability of a system in its actual life cycle conditions and estimating its time to failure is helpful in decision making to mitigate system risks. There are three approaches to prognostics: the physics-of-failure approach, the data-driven approach, and the fusion approach. A key requirement in all these approaches is the identification of the appropriate parameter(s) to monitor the collection of the data that can be employed to assess impending failure. This article presents the physics-of-failure approach, which uses failure modes, mechanisms, and effects analysis (FMMEA) to enhance prognostics planning and implementation. This article also presents the fusion approach to prognostics and the applicability of FMMEA to this approach. As an example, a case of generating FMMEA information, and using that to identify appropriate parameters to monitor, is presented.     

Using a multi-agent system to optimise resource utilisation in multi-site manufacturing facilities

Due to cost economies and better serving the global market, many enterprises expanded their manufacturing environment from a localised, single-site facility to more globalised, multi-site facilities. In order to take advantage of operating multi-site facilities, it is vital to make optimisation decisions of resource utilisation as if these facilities situated across different geographical locations are one integrated facility and take into account of the extended multi-site constraints and variables. This paper proposes a multi-agent system, using its characteristics of autonomy and intelligence, to integrate process planning and production scheduling across different facilities, so as to secure the most efficient and cost-effective plan and schedule to meet the demand. A currency-based agent iterative bidding mechanism is developed to facilitate the co-ordination of agents to achieve the goal. A genetic algorithm is employed to tune the currency values for agent bidding. In this paper, a case study is used for simulation in order to demonstrate the effectiveness and performance of the proposed agent system.

Stress disturbances arising from cut fibre and matrix in unidirectional metal matrix composites calculated by means of a modified shear lag analysis

A useful method to calculate stress disturbances arising from cut fibres is the so-called shear lag analysis, in which it is assumed that fibres act to carry tensile stress without transferring applied stress to the matrix, and the matrix acts to transfer stress to the fibres without carrying tensile stress. This assumption gives a limit for application. In the present work, with unidirectional metal matrix composites in mind, the usual two-dimensional shear lag analysis was modified to express the situation where both fibres and matrix act to carry applied stress and also to transfer stress. By using this modified method, tensile strain concentration in the fibres and matrix adjacent to cut fibres and matrix, and shear stresses at the interface between fibres and matrix, were calculated for some examples.     

Transforming traditional production system transactions to interoperable eBusiness-aware systems with the use of generic process models

Through the years, successful enterprises have been identified as the ones that were able to adapt their processes and ways of conducting business to the needs of their environment and the technological achievements of their times. This statement has not changed during recent years, but today, due to the major breakthrough of the internet and the possibilities it offers for a unified electronic marketplace, enterprises have to take advantage of the new technological tools offered, in order not only to adapt to this new emerging environment, but also to benefit from it and expand their operations in parallel with minimising costs. Achieving interoperability of the various production systems, and not only enabling hard-wired connectivity, seems to be the key that will unlock the gates leading to this newly established global market, and therefore enterprises need to focus more on their already established processes in order to be able to formulate a global standard for executing business transactions and cooperating smoothly with each other.     

From mitochondrial ion channels to arrhythmias in the heart: computational techniques to bridge the spatio-temporal scales

Computer simulations of electrical behaviour in the whole ventricles have become commonplace during the last few years. The goals of this article are (i) to review the techniques that are currently employed to model cardiac electrical activity in the heart, discussing the strengths and weaknesses of the various approaches, and (ii) to implement a novel modelling approach, based on physiological reasoning, that lifts some of the restrictions imposed by current state-of-the-art ionic models. To illustrate the latter approach, the present study uses a recently developed ionic model of the ventricular myocyte that incorporates an excitation-contraction coupling and mitochondrial energetics model. A paradigm to bridge the vastly disparate spatial and temporal scales, from subcellular processes to the entire organ, and from sub-microseconds to minutes, is presented. Achieving sufficient computational efficiency is the key to success in the quest to develop multiscale realistic models that are expected to lead to better understanding of the mechanisms of arrhythmia induction following failure at the organelle level, and ultimately to the development of novel therapeutic applications.
