Web应用程序的设计与分析

Ｗｅｂ迅速发展,并逐渐成为信息领域内最重要的一种媒介和开发手段。由于 ＨＴＴＰ协议的简单性,因而应用程序的开发也相对简单,但和数据库结合并动态创建页面的应用程序却很复杂。而且由于ＨＴＴＰ协议的无记忆性,使得基于Ｗｅｂ的应用程序相对一般的应用程序更为复杂。Ｗｅｂ的应用程序是软件工程一个新的应用领域,文章用ＵＭＬ方法来分析设计Ｗｅｂ应用程序,根据Ｗｅｂ应用程序的特点提出了概念页面的思想,并用页面框图,页面流来设计Ｗｅｂ页面。

基于渗流模型的影响力最大化算法

多数社交网络影响力最大化算法的研究只关注于所选种子节点集合的影响力是否最优,忽略网络自身传播影响力的固有能力。本文对网络进行渗流模拟,计算渗流后网络的主连通分量随着传播概率改变的趋势,并且求得主连通分量大小增加开始变快的相变点,从而计算网络自身传播影响力的固有能力。通过相变值与种子节点集合大小的换算,求得当前网络最佳的种子节点集合大小。将种子节点集合大小限制在最佳大小范围内即可获得最佳的影响力。在kareteclub、football、highschool和socdolphins社交网络数据集上进行实验,验证了该方法的有效性。     

A method of defuzzification based on the approach of areas' ratio

The new method of defuzzification of output parameters from the base of fuzzy rules for a Mamdani fuzzy controller is given in the paper. The peculiarity of the method is the usage of the universal equation for the area computation of the geometric shapes. During the realization of fuzzy inference linguistic terms, the structure changes from the triangular into a trapezoidal shape. That is why the universal equation is used. The method is limited and can be used only for the triangular and trapezoidal membership functions. Gaussian functions can also be used while modifying the proposed method. Traditional defuzzification models such as Middle of Maxima − MoM, First of Maxima − FoM, Last of Maxima − LoM, First of Suppport − FoS, Last of Support − LoS, Middle of Support − MoS, Center of Sums − CoS, Model of Height − MoH have a number of systematic errors: curse of dimensionality, partition of unity condition and absence of additivity. The above-mentioned methods can be seen as Center of Gravity − CoG, which has the same errors. These errors lead to the fact that accuracy of fuzzy systems decreases, because during the training root mean square error increases. One of the reasons that provokes the errors is that some of the activated fuzzy rules are excluded from the fuzzy inference. It is also possible to increase the accuracy of the fuzzy system through properties of continuity. The proposed method guarantees fulfilling of the property of continuity, as the intersection point of the adjustment linguistic terms equals 0.5 when a parametrized membership function is used. The causes of errors and a way to delete them are reviewed in the paper. The proposed method excludes errors which are inherent to the traditional and non- traditional models of defuzzification. Comparative analysis of the proposed method of defuzzification with traditional and non-traditional models shows its effectiveness.     

Transmission of vertical vibration through a seat: Effect of thickness of foam cushions at the seat pan and the backrest

The perception of vehicle ride comfort is influenced by the dynamic performance of full-depth foam used in many vehicle seats. The effects of the thickness of foam on the dynamic stiffness (i.e., stiffness and damping as a function of frequency) of foam cushions with three thicknesses (60, 80, and 100 mm), and the vibration transmitted through these cushions at the seat pan and the backrest were measured with 12 subjects (6 males and 6 females). With increasing thickness, the stiffness and the damping of the foam decreased. With increasing thickness of foam at the seat pan, the resonance frequencies around 4 Hz in the vertical in-line and fore-and-aft cross-axis transmissibilities of the seat pan cushion and the backrest cushion decreased. For the conditions investigated, it is concluded that the thickness of foam at a vertical backrest has little effect on the vertical in-line or fore-and-aft cross-axis transmissibilities of the foam at either the seat pan or the backrest. The frequencies of the primary resonances around 4 Hz in the vertical in-line transmissibility and the fore-and-aft cross-axis transmissibility of foam at the seat pan were highly correlated. Compared to sitting on a rigid seat pan with a foam backrest, sitting with foam at both the seat pan and the backrest reduced the resonance frequency in the vertical in-line transmissibility of the backrest foam and increased the associated transmissibility at resonance, while the fore-and-aft cross-axis transmissibility of the backrest was little affected. Compared to sitting without a backrest, sitting with a rigid vertical backrest increased the resonance frequency of the fore-and-aft cross-axis transmissibility of the seat pan cushion and increased the transmissibility at resonance.Relevance to industryThe transmissibility of a seat is determined by the dynamic properties of the occupant of the seat and the dynamic properties of the seat. This study shows how the thicknesses of foam at a seat pan and foam at a backrest affect the in-line and cross-axis transmissibilities of the foams at the seat pan and the backrest. The findings have application to the design of vehicle seats to minimise the transmission of vibration to the body.

Teacher education in IT in Germany

Abstract In 1988 the eleven West-German Kultusminister , with responsibility for the school systems in their respective Bundeslaender , reached agreement with the Federal Ministry of Education and Science on the broad concept of 'Information and Communications Technology', ITG. After four years of discussion it was agreed that ITG should be introduced into the secondary level of the general schools. In spite of strong disagreements about the ways and speed of implementation, and after several years of experiments, important parts of the concept have become a reality in practically all of the old Bundeslaender. While acknowledging the complexity of the German educational system the paper attempts to outline the development of the concept of Information and Communications Technology and its consequences in teacher education. The development in the eastern part of Germany, the former GDR, has been completely different to that in the western part and this is also commented upon in the paper.     

融合分区与Canny泛函的水平集对猴脑提取的研究

The traditional level set has randomness in the location selection of the initial contour, and lacks the processing of edge information. Therefore, accurate extraction of brain tissue edges cannot be achieved. Therefore, firstly, the level set algorithm of fusion partition and Canny functional fuses the idea of partition and combines the morphological information of each region to complete the initial contour position selection, so that the initial contour contains more brain tissue, and improve the efficiency of brain tissue extraction. Secondly, the Canny operator is integrated into the energy functional, which improves the accuracy of detecting the edge of the macaque brain tissue while retaining the superiority of the traditional level set on the uneven grayscale image. Results show that the algorithm achieves accurate extraction of macaque brain tissue with an accuracy of up to 86%.     

可拓聚类的科教人际网络节点重要性动态分析方法

目前大多数研究对复杂社会网络关键节点影响力的识别都是静态的，缺乏动态变化的分析。采用可拓聚类方法对动态变化下的科教人际网络进行量化分析，首先以多属性决策法计算每个节点重要性，再利用变异系数权重法计算得该节点综合重要性量值，之后划分等级并取标准正域和正域区间，利用可拓关联函数计算每个节点与每个等级的关联度，关联度值最大的等级即为该节点对应等级，最后分析同一社会网络节点在不同时间点的重要性等级变化。可拓聚类方法尝试从动态上对网络节点重要性进行把握，最后通过实例验证了该方法的有效性。     

An approach to the synthesis of fuzzy stabilization systems with a priori unknown model of an object

A method of synthesis of fuzzy stabilization systems for a broad class of dynamic objects under the assumption that the mathematical model of the object is not known a priori is proposed. The control is formulated in the form of a proportional law of adjustment as a function of a macro-variable; the square of the Euclidean norm of the phase variables is adopted as the macro-variable. An analogous variable characterizes the distance of the object from the equilibrium position. Despite the simplicity of the control law, its sign remains constant due to the fact that the macro-variable is positive-definite over the entire phase space. The switching times of the signals are determined by fuzzy identification of the system’s dynamic modes on the basis of measurement of the derivatives of the macro-variable.     

基于遮挡关系推理的输电线路图像金具检测

实现输电线路图像典型金具的精准检测是进行其缺陷检测的前提。针对通用目标检测模型对密集分布、遮挡严重的金具检测精度较低、易出现漏检等问题,提出了一种结合金具间遮挡结构信息和场景关联信息的典型金具检测方法。基于经典的Faster R-CNN模型提取金具特征作为节点,提取整张图像特征作为金具场景关联信息,学习金具标注框间相交区域信息作为金具遮挡关系信息,并采用图同时建模金具特征、场景关联信息和遮挡关系信息,通过门控循环单元信息传递机制构建结构推理模块完成金具类别和位置的联合推理检测。为了验证所提方法的有效性,选取了8类存在遮挡连接关系的金具进行实验,其中,原始Faster R-CNN模型的mAP值为81.30%,改进模型的mAP值为84.15%。实验结果表明,本文方法一定程度上提高了遮挡严重金具的检测精度,为后续的金具故障诊断奠定良好的基础。
