A unified modelling and simulating integration is necessary to analyse multidisciplinary systems with an effective method, adapting to multiple disciplinary domains. In this process, it is well known that 2D or 3D mechanical multibody dynamic analysis is a bottleneck problem. Based on the linear graph theory and object-oriented module technology, we propose EELG (extensible element linear graph) method that can be applied to automatically generate component-level dynamic equations for describing multidisciplinary systems, first encapsulated linear graph into the element linear graph, defined element through and circuit matrixes respectively deserved from the across-graph and through-graph of an element linear graph, and made the member module with the hierarchy, reusing and extensibility. By linking these standard modules successively to model a particular system, the component-level dynamic equations would be automatically generated by topology matrixes operation. This approach provides greater modelling flexibility and supports the model's versatility
多学科系统分析需要统一的建模和仿真集成,以有效的方法适应多学科领域。在此过程中,二维或三维力学多体动力学分析是一个瓶颈问题。基于线性图理论和面向对象模块技术,提出了可扩展元素线性图(EELG)方法,该方法可用于自动生成描述多学科系统的组件级动态方程,首先将线性图封装到元素线性图中,从元素线性图的横图和贯通图中分别定义元素通过矩阵和电路矩阵,并构造具有层次结构的成员模块;重用和可扩展性。将这些标准模块依次连接起来,对某一特定系统进行建模,通过拓扑矩阵运算自动生成组件级动态方程。这种方法提供了更大的建模灵活性,并支持模型的多功能性

Autonomous Distributed Scheduling Adjustment Function with Interchanging Operations 具有互换操作的自治分布式调度调整功能
Pub Date : 2006-10-01 DOI: 10.1109/COASE.2006.326913

This paper deals with the partial scheduling adjustment in the autonomous distributed scheduling method. The scheduling adjustment for the production system is required when uncertainty occurs. In that case, it does not need to adjust the whole schedule, but only the partial schedule which receives a direct influence by uncertainty according to the variable situation. From the viewpoint of the distributed system, to implement a function which adjusts such a partial schedule, each machine needs to manage schedule and exchange information. It has been studied by some researchers in recent years. However, the partial scheduling adjustment has not been controlled to change the processing sequence of operations in a machine, namely interchanging operations. Therefore, we propose realizing a function interchanging operations in a machine to diminish the influence occurred by a delay of a certain operation
研究了自主分布式调度方法中的局部调度调整问题。当不确定性发生时,需要对生产系统进行调度调整。在这种情况下,不需要对整个计划进行调整,只需根据变化的情况对直接受到不确定性影响的部分计划进行调整。从分布式系统的角度来看,要实现对这样一个局部调度进行调整的功能,每台机器都需要进行调度管理和信息交换。近年来,一些研究人员对其进行了研究。但是,还没有控制局部调度调整来改变机器中操作的加工顺序,即互换操作。因此,我们建议在机器中实现功能互换操作,以减少某一操作的延迟所产生的影响

In this paper, the techniques of an experiment-based brush footprint acquisition method and a genetic algorithm (GA)-based brush stroke generation scheme are combined. The combined method is applied to replicating a given Chinese character. Additionally, a new method to come up with the brush stroke skeleton to facilitate Bezier representation of the brush stroke, rather than the thinning algorithm in previous works, is also incorporated. Actual experiments were conducted to demonstrate the performance of combined method and to compare with the original character. The present paper is part of an endeavour to attempt replicating the works of famous past calligraphers.

Near infrared reflectance spectroscopy (NIRS) appears to be a rapid and convenient non-destructive technique that can measure the quality and compositional attributes of many substances. This paper assesses the ability of NIR reflectance spectroscopy to estimate the pH values of bayberry juice. Spectra were collected from 76 juice samples and data was expressed as absorbance, the logarithm of the reciprocal of reflectance (log 1/R). The absorbance data was subsequently compressed using wavelet transformation. Three models to predict the acidity in bayberry juice were constructed. A prediction model based on principle component analysis-multiple linear regression-back propagation (PCA-MLR-BP) was found to be superior (r=0.934, RMSEP=0.263) to models based on PCA-BP and MLR-BP

Performance evaluation and schedule optimization of cluster tools is challenging, especially when the process times are with uncertainty. In this paper, the critical path method (CPM) is used to analyze the throughput of multi-cluster tools with fixed action sequence. Slacks of non-critical path actions are studied and integrated to find the average cycle time of the cluster tool. A thin film tool from Novellus is used as an example to explain this methodology

Computing fault probability is an effective method of predicting the possible weakness of new product. Aiming at computing fault probability of each component of new product, and ensuring simplification of computational process and reasonableness of result, in the paper, according to design proposal and layering of new product, fault tree meta-model (FTMM) is established based on node-knowledge-representation method (NKRM) to express logical relation between each failure in different level of product and collaboration between each part. Secondly, RST and Bayes theory are applied to mining the decision rule of FTMM which is that fault of part in lower level causes fault of part in upper level, and joint probability of part is computed directly which avoids difficulty of computing because of unknown prior probability, then fault probability of part is computed. On this basis, weighted mean algorithm based on Bayes-and-RST (BRMA) is proposed to revise fault probability further, thus the result is more exact and reasonable, which can help product development personnel predict possible weakness of product in time and carrying out reliability design further in the design stage of new product development. Finally, an instance is analyzed

Epileptic electroencephalogram data contains transient components and background activities. One of the transients is spike, which occurs randomly with short-duration. Spike detection in EEG is significant for clinical diagnosis of epilepsy. Since it is time consuming to scan spikes manually, an automatic spike detection method is necessary. In this paper, we introduce an automatic spike detection method in epileptic EEG based on morphological filter. Firstly, an average weighted combination of open-closing and close-opening morphological operator, which eliminates statistical deflection of amplitude, is utilized to extract spike component from epileptic EEG. Then, according to the characteristic of spike component, the structure elements are constructed with two parabolas, and a new criterion is put forward to optimize center amplitude and width of the structure elements. The proposed method is evaluated by simulated epileptic EEG data. Results show that background activity is fully restrained and spike component is well extracted. Finally, the method is applied to normal and epileptic EEG data which are actually recorded from nine testees. The average detection rate of spikes is 91.62% and no false detection for normal EEG signals
癫痫脑电图数据包含瞬态成分和背景活动。其中一种瞬态是脉冲,它随机发生,持续时间短。脑电图峰检测对癫痫的临床诊断有重要意义。由于手动扫描尖峰费时,因此需要一种自动尖峰检测方法。本文介绍了一种基于形态学滤波的癫痫脑电峰自动检测方法。首先,利用开闭和闭开形态算子的平均加权组合,消除了振幅的统计偏转,提取癫痫脑电图的尖峰分量;然后,根据尖峰分量的特点,用两条抛物线构造结构单元,并提出了优化结构单元中心幅值和宽度的新准则。通过模拟癫痫脑电图数据对该方法进行了验证。结果表明,背景活性得到了充分的抑制,脉冲成分得到了很好的提取。最后,将该方法应用于正常和癫痫患者的脑电图数据。平均检测率为91.62%,对正常脑电信号无误检

Flexibility is the keyword in the modern industrial world. Automatic generation of collision- and blocking free, time optimal schedules for industrial robot cells is thus motivated. While a lot of attention has been paid to the control of industrial systems, as well as to the development of general optimization algorithms, there is still a need to properly combine these two research areas. This paper discusses two scheduling algorithms, designed for industrial robot cells, in terms of performance. A novel heuristic to an A*-based algorithm, operating on discrete event systems, is proposed and benchmarked against the well-known MILP algorithm

In the design process of complex systems, the use of physical prototypes presents many drawbacks in terms of both costs and time. Virtual prototyping tools allow instead the designer to extensively study the system behavior in a variety of configurations, providing the possibility of performing focussed tests and comparing the effectiveness of different solutions before the physical realization of the prototype. When building the virtual prototype, the choice of a suitable model for each of the interacting components is crucial for achieving reliable results. In the simulation of racing vehicles, such as cars or motorcycles, it is common practice to represent the engine torque by means of stationary maps depending on a finite number of constant values of the throttle fraction and the rotational speed of the crankshaft. Although simple to implement and characterize, such model cannot reproduce dynamic transients, and therefore may not be adequate when a detailed analysis of the vehicle behavior is required. In this paper we present the characterization and identification of a nonlinear dynamic model for a two-stroke internal combustion high-performance engine, to be used in the ADAMS multibody virtual prototyping environment. The model is obtained by using neural networks and validated on experimental data
在复杂系统的设计过程中,物理原型的使用在成本和时间方面都存在许多缺点。虚拟原型工具允许设计人员在各种配置下广泛地研究系统行为,提供执行集中测试的可能性,并在原型的物理实现之前比较不同解决方案的有效性。在构建虚拟原型时,为每个相互作用的组件选择合适的模型对于获得可靠的结果至关重要。在赛车的模拟中,例如汽车或摩托车,通常的做法是通过固定的地图来表示发动机扭矩,这取决于有限数量的节气门分数和曲轴转速的恒定值。虽然实现和表征简单,但这种模型不能再现动态瞬态,因此在需要对车辆行为进行详细分析时可能不足够。本文提出了一种用于ADAMS多体虚拟样机环境的二冲程内燃机非线性动力学模型的表征和辨识。利用神经网络建立了该模型,并用实验数据进行了验证

The planning problem consists in determining the set of elective patients that would be operated in each period over a planning horizon in order to minimize patients related costs and overtime costs of operating rooms. A stochastic integer programming model is proposed. Lagrangian relaxation is used to decompose the planning problem into period-level sub-problems that are solved by a dynamic programming method. The dual problem is solved iteratively using a sub-gradient algorithm. Feasible plans are derived from relaxed solutions using a heuristic and improved with a "local search heuristic". This approach results in both near-optimal solution and a lower bound to assess the degree of optimality. Numerical experimentations show that solutions within 1% of the optimum are obtained in a short computation time for problems of practical sizes
本文研究了当手术室容量由择期病人和急诊病人共享时择期手术的计划问题。计划问题包括在计划范围内确定每个时期将进行手术的选择性患者的集合,以最小化患者相关成本和手术室的加班成本。提出了一种随机整数规划模型。利用拉格朗日松弛将规划问题分解为周期级子问题,用动态规划方法求解。对偶问题采用次梯度算法迭代求解。采用启发式方法从松弛解中导出可行方案,并用“局部搜索启发式”方法进行改进。这种方法产生了近似最优解和评估最优程度的下界。数值实验表明,对于实际规模的问题,可以在较短的计算时间内得到1%以内的最优解
