The approximation methods of mathematics are widely used in theory and practice for several problems. In the framework of the paper a novel tensor-product based approach for representation of neural networks (NNs) is proposed. The NNs in this case stand for local models based on which a more complex parameter varying model can numerically be reconstructed and reduced using the higher order singular value decomposition (HOSVD). The HOSVD as well as the tensor-product based representation of NNs will be discussed in detail.
数学中的近似方法在理论和实践中广泛应用于许多问题。在本文的框架下,提出了一种新的基于张量积的神经网络表示方法。在这种情况下,神经网络代表局部模型,在此基础上,可以使用高阶奇异值分解(HOSVD)对更复杂的参数变化模型进行数值重构和简化。我们将详细讨论HOSVD以及基于张量积的神经网络表示。

Pub Date : 2011-06-23 DOI: 10.1109/INES.2011.5954717

Definition of product in model space includes contextual decisions and relies upon background of those decisions. This background influences decisions on engineering objects in a very complex way. Appropriately selected combination of engineering object variants may be a compromise in a coordinated product definition. The authors of this paper recognized that conventional model space construction in recent product lifecycle management has not model representation capabilities for the above background. Paper starts with a discussion about influences on product definition in the course of product development in model space. Following this, the currently prevailing and the proposed process of human influence are explained and compared. As the main contribution in the paper, methods for coordinated control of product definition, extended engineering object space, and coordinated change requests for adaptive action generation are introduced. Finally, execution of enabled adaptive action and implementation in PLM system are explained as implementation issues.
模型空间中的产品定义包括上下文决策,并依赖于这些决策的背景。这种背景以一种非常复杂的方式影响着工程对象的决策。在协调的产品定义中,适当选择工程对象变体的组合可能是一种折衷。本文的作者认识到,当前产品生命周期管理中传统的模型空间构建方法不具备上述背景下的模型表示能力。本文首先讨论了模型空间中产品开发过程中对产品定义的影响。在此之后,解释和比较了目前流行的和拟议的人类影响过程。本文主要介绍了产品定义的协调控制方法、扩展工程对象空间的方法和自适应动作生成的协调变更请求的方法。最后,将启用自适应动作的执行和在PLM系统中的实现解释为实现问题。

Interpolative reasoning in sparse rule base has been an important research topic in the field of artificial intelligence. To solve effectively the problem of reasoning in multivariable sparse rule base whose resulting consequences are restricted in a finite set, this paper developed a new interpolative reasoning approach and offered its algorithm. The approach deduced consequent results by converting domains of antecedent and consequent variables into ternary qualitative spaces and building ternary qualitative function among such spaces as model of system for calculation. By applying this approach to an example, the paper illustrated that the new approach is more accurate and simple than the existing interpolative reasoning methods for such problem.
稀疏规则库中的插值推理一直是人工智能领域的一个重要研究课题。为了有效地解决多变量稀疏规则库中结果限制在有限集合中的推理问题,提出了一种新的插值推理方法并给出了算法。该方法将前因变量和后因变量的域转换为三元定性空间,并在计算系统模型等空间之间建立三元定性函数,推导出相应的结果。通过实例说明,该方法比现有的插值推理方法更准确、更简单。

This paper presents a clock built around the MC9S12XDP512 microcontroller using an LCD display. This clock shows the time (hours, minutes, and seconds) and the date (year, month, day). The MC9S12XDP512 development board from Freescale has no integrated LCD module, so an external module had to be connected. The date is fully displayed (four digit years) and has an implemented algorithm to make the difference between the months with 30 or 31 days and to distinguish between February having 28 or 29 days. The clock has an adjustment option. All the programming is performed in assembly.

This paper describes a solution to decrease maintenance costs for the Éole Bridge expansion joints. The developed monitoring system is based on the analysis of the sound level and frequencies produced by the vehicles passing in these expansion joints, allowing an estimation of the joint overall structural damage. The system issue alerts to maintenance teams, improving their response time and preventing the increase of the damaged sections, leading to reduced maintenance costs and less road stopping time, and improving the quality delivered to the users of the bridge. The objective of the work presented was to make an adequate signal analysis in order to identify the progress of damaged sections in each inspected expansion joint.
本文介绍了一种降低Éole桥梁伸缩缝维修费用的解决方案。开发的监测系统是基于对通过这些伸缩缝的车辆产生的声级和频率的分析,从而可以估计接缝的整体结构损坏情况。该系统向维修团队发出警报,提高了他们的响应时间,防止了受损路段的增加,从而降低了维修成本,减少了道路停车时间,提高了交付给桥梁用户的质量。所提出的工作目标是进行充分的信号分析,以便确定每个被检查的伸缩缝中损坏部分的进展情况。

Harmonic modulation in control to reduce oscillations in mechatronic systems 谐波调制控制,以减少机电系统的振荡
Pub Date : 2011-06-23 DOI: 10.1109/INES.2011.5954763
P. Hauptle, P. Hubinský, G. Gruhler
In this contribution our interest focuses on applications with a mechatronic drive (MD) where electronics, a motor and a gear-box i.e. a harmonic drive(R) is merged to one module. Every mechatronic system (MS) has one or more resonances. Due to the modeling of such a system, two different challenges regarding oscillations has to be solved by control. Namely the ”transient”-effects as well as the ”semi-stead-state”-effects arise oscillations. We would like to introduce a new feedforward method where undesirable oscillations can be reduced. Beside simulation results also results from our experimental setup due to acceleration measurements are discussed in the following.
在这个贡献中,我们的兴趣集中在机电驱动(MD)的应用上,其中电子,电机和齿轮箱即谐波驱动(R)合并到一个模块。每个机电系统(MS)都有一个或多个共振。由于这样一个系统的建模,关于振荡的两个不同的挑战必须通过控制来解决。即“瞬态”效应和“半稳态”效应引起振荡。我们想介绍一种新的前馈方法,它可以减少不必要的振荡。除了仿真结果外,还讨论了由于加速度测量而产生的实验结果。

Online adaptation model for accelerated cooling process in plate mill 板轧机加速冷却过程在线自适应模型
Pub Date : 2011-06-23 DOI: 10.1109/INES.2011.5954736
C. K. Jung, C. S. Lee
Two online adaptation models tuning the flowrate of cooling water in plate mill are developed based on the feedback and feedforward control algorithm. In the feedback control based model, a multiplication factor is adopted which is composed of three adaptation coefficients. The calculations of the three coefficients are designed taking process variations into account. After tested on an offline simulator, the adaptation model is installed on the online process resulting in 10% increase of the accuracy rate of the final cooling temperature. And a neural network model is developed to factor in the variations of the prior processes. It uses 24 process variables as inputs and predicts the final cooling temperature. Comparing with the measured data, the predicted temperatures show an accuracy of ±15 °C.

Tissue engineering's main objective is to create therapeutic constructs in vitro, capable to replace or remedy the functions of the tissue affected by different disease or totally destroyed. In order to obtain these constructs, the living cells are cultured on the different structure biomaterial. It has been shown that these constructs have properties which are similar to ones of human tissue, if the seeding is uniform. The paper presents a set of simulations of cell spreading on the plane surface of a biomaterial, based on the Metropolis Monte Carlo method. The model taken into account is formed of a cell aggregate placed on the planar surface of a parallelepipedic biomaterial. We study the influence of the cell-substrate and cell-medium interfacial tension parameters on the cell spreading process, analysing the number of cells attached to the biomaterial and the spreading rate of the cells. We also analyze the evolution of the centre of mass for the same value of cell-substrate interfacial tension and for different values of cell-medium interfacial tension. Experiments show an uniform and rapid cell spreading results if the cell-substrate and cell-medium interfacial tension have lower values.
组织工程的主要目标是在体外创造治疗性结构,能够替代或修复受不同疾病影响或完全破坏的组织的功能。为了获得这些结构,将活细胞培养在不同结构的生物材料上。已经证明,如果种子是均匀的,这些结构具有类似于人体组织的性质。本文提出了一套基于Metropolis蒙特卡罗方法的细胞在生物材料平面上扩散的模拟方法。所考虑的模型是由放置在平行六面体生物材料平面上的细胞聚集体形成的。我们研究了细胞-基质和细胞-介质界面张力参数对细胞扩散过程的影响,分析了附着在生物材料上的细胞数量和细胞的扩散速度。我们还分析了相同的细胞-基质界面张力值和不同的细胞-介质界面张力值下质心的演变。实验结果表明,当细胞-基质和细胞-介质界面张力较小时,细胞扩散均匀,扩散速度快。
