Nowadays, commercial activities on the internet and media need to be protected by increasing of security, using the 2D Barcode with a digital watermark in security field. This paper proposes that QR Code (Quick Response Code) is embedded with an invisible watermark by using Discrete-Cosine-Transform, or DCT for an information hiding (secret information) within the group through the QR Code image with invisible watermark. The encoding process used the DCT to allow QR Code image to be broken up into different frequency bands using block DCT based method; comparison between mid-band coefficients then embed with the invisible watermarking information into the middle frequency bands. The watermark extraction system determines a watermark in the QR Code image by reverse the embedded process from the invisible watermark. This QR Code image with invisible watermark preserves an information hiding text in the QR Code image.
如今,网络和媒体上的商业活动需要提高安全性来保护,在安全领域使用带有数字水印的二维条码。本文提出利用离散余弦变换(Discrete-Cosine-Transform, DCT)方法,通过带有不可见水印的QR码图像,对组内的信息(秘密信息)进行隐藏,并嵌入不可见水印的QR码(Quick Response Code)。编码过程采用基于分块DCT的方法将QR码图像分解成不同的频段;然后将不可见的水印信息嵌入到中频段。水印提取系统通过对不可见水印的反向嵌入过程来确定QR码图像中的水印。这个不可见水印的QR码图像保留了QR码图像中的信息隐藏文本。

Research on culture and web usability has highlighted influences of culture on web usability. However, the issue of age group differences has been neglected, as participants were mostly university students which represent only one age group. People of different age groups are different, not only in their physical attributes, but also in their cognitive and socioemotional attributes. This paper investigated the influence of age group differences on usability of culturally accommodated websites. Research participants were tested with three different web prototypes. Two of them represented two different cultures, while another one was designed to be neutral to the other two cultures. The results were evaluated both subjectively and objectively. The results indicate that there were interaction effects between age group and culture, as represented in each prototype, on web usability was significantly different. In conclusion, interpretations of interaction effects are discussed.
文化与网络可用性的研究凸显了文化对网络可用性的影响。然而,年龄组差异的问题被忽视了,因为参与者大多是大学生,只代表一个年龄组。不同年龄段的人不仅在身体属性上存在差异,在认知和社会情感属性上也存在差异。本文研究了年龄群体差异对文化适应网站可用性的影响。研究参与者被测试了三种不同的网页原型。其中两个代表了两种不同的文化,而另一个则被设计成与其他两种文化保持中立。对结果进行了主客观评价。结果表明,不同年龄层和不同文化对网络可用性的交互影响存在显著差异。最后,讨论了相互作用效应的解释。

Improve the SOM classifier with the Fuzzy Integral technique 用模糊积分技术改进SOM分类器
Pub Date : 2012-02-16 DOI: 10.1109/ICTKE.2012.6152395

As Self-organizing map (SOM) neural network is implemented as a pattern classifier. According to the decision process of the SOM classifier, the traditional technique, called the winner-take-all, is employed to search the final class of an unknown input. In practice, some prototypes on the SOM classifier might not be representatives of purity class regions. Hence, the decision process of the SOM requires information about both the winner prototype and its neighbors to improve an accuracy rate. In this paper, the Fuzzy Integral decision technique is applied to aggregate information about the winner prototype and its neighbors for determining the final class of an unknown input. The experimental results of the UCI datasets showed that the proposed decision technique could improve accuracy rates better than the traditional technique.
自组织映射(SOM)神经网络是一种模式分类器。根据SOM分类器的决策过程,采用传统的赢家通吃的方法对未知输入的最终类别进行搜索。在实践中,SOM分类器上的一些原型可能不是纯度类区域的代表。因此,SOM的决策过程需要关于获胜者原型及其相邻原型的信息来提高准确率。本文将模糊积分决策技术应用于获胜者原型及其邻居的信息聚合,以确定未知输入的最终类别。UCI数据集的实验结果表明,所提出的决策技术比传统的决策技术能更好地提高准确率。

In this paper, we proposed a method for developing Influence Diagrams by using the engine namely, Structural Modeling, Inference, and Learning Engine (SMILE). An influence diagram is a simple visual representation of a decision problem. It can be used to assist in rational decision making for different purposes. We proposed a practical method and a piece of source code in C#.net to build an influence diagram based on a SMILE engine. We presented the steps on how to set four types of nodes and their properties in an influence diagram using C#.net. This piece of source code also includes the method to construct each component such as decision, chance, deterministic, value and arcs between the nodes in the diagram. It also includes the method to perform Bayesian updating and Bayesian inference according to Baye's theorem. The developer can apply this proposed method for the extension model of influence diagrams. He or she can also embed this piece of source code in an existing decision support application.
在本文中,我们提出了一种利用结构建模、推理和学习引擎(SMILE)来开发影响图的方法。影响图是决策问题的简单直观表示。它可以用来帮助为不同目的的理性决策。本文提出了一种实用的方法,并在c# .net中编写了一段基于SMILE引擎构建影响图的源代码。我们介绍了如何使用c# .net在影响图中设置四种类型的节点及其属性的步骤。这段源代码还包括构造每个组件的方法,例如图中节点之间的decision、chance、deterministic、value和弧线。还包括根据贝叶斯定理进行贝叶斯更新和贝叶斯推理的方法。开发人员可以将该方法应用于影响图的扩展模型。他或她还可以将这段源代码嵌入到现有的决策支持应用程序中。

Data warehouse (DW) testing is a very critical stage in the DW development because decisions are made based on the information resulting from the DW. So, testing the quality of the resulting information will support the trustworthiness of the DW system. A number of approaches were made to describe how the testing process should take place in the DW environment. In this paper we will present briefly these testing approaches, and then a proposed matrix that structures the DW testing routines will be used to evaluate and compare these approaches. Afterwards an analysis of the comparison matrix will highlight the weakness points that exist in the available DW testing approaches. Finally, we will point out the requirements towards achieving a homogeneous DW testing framework. In the end, we will conclude our work.
数据仓库(DW)测试是DW开发中非常关键的阶段,因为决策是基于DW产生的信息做出的。因此,测试结果信息的质量将支持DW系统的可信度。提出了许多方法来描述测试过程应该如何在DW环境中进行。在本文中,我们将简要介绍这些测试方法,然后构建DW测试例程的建议矩阵将用于评估和比较这些方法。然后,对比较矩阵的分析将突出现有DW测试方法中存在的弱点。最后,我们将指出实现同构DW测试框架的需求。最后,我们将结束我们的工作。

A new method to select suitable generators for the purpose of power scheduling has been proposed in this paper, namely Fast Voltage Stability Index Generation Tracing (FVSI-GT). Contrary to previous power tracing techniques which select the generators based on the magnitude of traced power, the proposed technique performs the generator selection based on the stability index contributed by individual system's generator. After tracing the contributed stability index, the sizing process of generators' power to be dispatched has been performed via a new hybrid optimization algorithm; Blended Crossover Continuous Ant Colony Optimization (BX-CACO). From experiment and validation on IEEE 30 bus reliability test system (RTS), it is revealed that FVSI-GT exhibits great performance as the method capable to select exact generators with the enhancement of system's static stability, losses and fuel cost minimization with fast optimization via BX-CACO.
本文提出了一种以电力调度为目的选择合适发电机的新方法——快速电压稳定指数发电跟踪(FVSI-GT)。与以往基于跟踪功率大小选择发电机的电力跟踪技术不同,该技术基于单个系统发电机贡献的稳定性指标进行发电机选择。在对贡献的稳定指标进行跟踪后,通过一种新的混合优化算法进行发电机待调度功率的确定过程;混合交叉连续蚁群优化(BX-CACO)。在IEEE 30总线可靠性测试系统(RTS)上的实验和验证表明,FVSI-GT方法具有良好的性能,可以通过BX-CACO快速优化,提高系统的静态稳定性、损耗和燃料成本最小化。

Text categorization is the main issue which affects search results. Moreover, most approaches suffer from the high dimensionality of feature space. To overcome this problem, the use of feature selection techniques with statistical text categorization is investigated. The methods were evaluated based on Chi-Square, Information Gain and Gain Ratio. The data used to test the system consisted of 1,510 documents from 2009-2010, word segmentation algorithm to key-phrase 4,408 attributes and single word 2,184 attributes. Classification techniques applied Decision Tree (ID3), Naïve Bayes (NB), Support Vector Machine (SVM) and k-nearest neighbor (KNN). Results showed that the Support Vector Machine was found to be the best technique with accuracy of a single word at 84% and key-phrase at 74% based on feature selection with Chi-Square, Information Gain and Gain Ratio with F-measure. In future research, application of text to the semantic system should be investigated further.
文本分类是影响搜索结果的主要问题。此外,大多数方法都受到特征空间高维性的影响。为了克服这一问题,研究了特征选择技术与统计文本分类的结合。根据卡方、信息增益和增益比对方法进行评价。用于测试系统的数据包括2009-2010年的1510份文档,分词算法对关键短语4408个属性和单个单词2184个属性进行分词。分类技术采用决策树(ID3)、Naïve贝叶斯(NB)、支持向量机(SVM)和k近邻(KNN)。结果表明,基于卡方特征选择、信息增益和增益比(F-measure)的特征选择,支持向量机的单字准确率为84%,关键短语准确率为74%。在未来的研究中,文本在语义系统中的应用有待进一步研究。

In this paper we propose a pricing model for Mobile Virtual Network Operator's investment in Enhanced-Universal Mobile Telecommunication System (E-UMTS) networks. We conceptualize the relationship among MNO, MVNO, and other related variables in the proposed pricing model. Next, we study financial options design for MVNO's investment in Enhanced-Universal Mobile Telecommunication System (E-UMTS) networks. We also present the relationship between MNO and MVNO and investigate the total costs, total revenues, and net profit. Finally, we propose a real options analysis as a tool for valuing strategic investments and decisions of the MVNO in enhanced UMTS network market. The aim is to investigate the weighted average cost of capital (WACC) of the MVNO and net present value (NPV). The cases are examined and analyzed both qualitatively and quantitatively, using realistic assumption and parameters. The analysis of the results obtained from the model focuses on of capital expenditure (CapEx) and operational expenditure (OpEx) to provide recommendations which may be utilized and made a greater contribution in the MVNO's investment decision making process.

In this paper, computational and simulation results are presented for the performance of the fitness function, decision variables and CPU time of the proposed hybridization method of Mesh Adaptive Direct Search (MADS) and Genetic Algorithm (GA). MADS is a class of direct search algorithms for nonlinear optimization. The MADS algorithm is a modification of the Pattern Search (PS) algorithm. The algorithms differ in how the set of points forming the mesh is computed. The PS algorithm uses fixed direction vectors, whereas the MADS algorithm uses random selection of vectors to define the mesh. A key advantage of MADS over PS is that local exploration of the space of variables is not restricted to a finite number of directions (poll directions). This is the primary drawback of PS algorithms, and therefore the main motivation in using MADS to solve the industrial production planning problem is to overcome this restriction. A thorough investigation on hybrid MADS and GA is performed for the quality of the best fitness function, decision variables and computational CPU time.
本文给出了网格自适应直接搜索(MADS)和遗传算法(GA)杂交方法的适应度函数性能、决策变量性能和CPU时间性能的计算和仿真结果。MADS是一类用于非线性优化的直接搜索算法。MADS算法是对模式搜索(PS)算法的改进。这些算法的不同之处在于如何计算形成网格的点集。PS算法使用固定的方向矢量,而MADS算法使用随机选择的矢量来定义网格。与PS相比,MADS的一个关键优势是对变量空间的局部探索不限于有限数量的方向(轮询方向)。这是PS算法的主要缺点,因此使用MADS来解决工业生产计划问题的主要动机是克服这一限制。对混合MADS和遗传算法的最佳适应度函数、决策变量和计算CPU时间的质量进行了深入的研究。
