The wireless communications has revolutionized human life, but has also created several issues relating to its usage. One of the biggest issues involved in use of the wireless communications is related to network performance. The process of refining the network routine by changing activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems is network management. Network operations will be executed by authenticated authorities like administrator. The increasing complexity of networks has promulgated a dire need for monitoring the traffic of the network which helps to identify any failure in the performance of the network. It also helps to identify attacks in the network and predicts the network status. This paper evaluates the performance of router based network traffic monitoring techniques such as SNMP, RMON and Netflow and the implementation of these techniques is carried out to ascertain the most effective monitoring technique among the three. The NS-2 simulator is used for implementation. SNMP performs better than the other two methods for WLAN.
无线通信已经彻底改变了人类的生活,但也产生了一些与使用有关的问题。无线通信中涉及的最大问题之一是与网络性能有关。通过改变与网络系统的操作、管理、维护和供应有关的活动、方法、程序和工具来改进网络例行程序的过程就是网络管理。网络操作将由经过身份验证的权威机构(如管理员)执行。随着网络的日益复杂,对网络流量进行监控的需求日益迫切,这有助于识别网络性能中的任何故障。它还有助于识别网络中的攻击,预测网络状态。本文对基于路由器的网络流量监控技术(如SNMP、RMON和Netflow)的性能进行了评估,并对这些技术进行了实现,以确定三者中最有效的监控技术。采用NS-2模拟器实现。对于WLAN, SNMP的性能优于其他两种方法。

Application Programming Interface (API) in software development acts as an important milestone for software productions. It is believed that API usability impacts upon ease-in-use, operationability and acceptability among its audience. Likewise, an ever increasing need for extending and integrating Usability Engineering (UE) has become vital for the success of software products. Earlier researches within this domain do not address API's usability via a component-based framework approach. The proposed framework emphasizes on consolidated formulation of various usability and quality models to derive chunks of dimensional variables. Further the paper highlights API usability practices and heuristics applied in API development process and discusses API product's artifacts component to be used in deriving further product-related components to support enhancing usability.
软件开发中的应用程序编程接口(API)是软件生产的一个重要里程碑。人们认为,API的可用性影响着用户的易用性、可操作性和可接受性。同样,对扩展和集成可用性工程(UE)的不断增长的需求已经成为软件产品成功的关键。该领域的早期研究没有通过基于组件的框架方法来解决API的可用性问题。所提出的框架强调各种可用性和质量模型的统一表述,以派生维度变量块。此外,本文重点介绍了API可用性实践和在API开发过程中应用的启发式方法,并讨论了API产品的工件组件,用于派生进一步的产品相关组件,以支持增强可用性。

Non-interactive or low interactive media such as radio can become highly immersive and realistic, engendering a compelling sense of presence for the participant. An example of low interactive technology is a simple Image-based Virtual Reality (IBVR) environment which has no perceptual characteristics of the interaction with haptic sensations which can provide high user's presence. Therefore, the study investigates whether IBVR environment can elicit user's presence even without computer animation? Furthermore, the three pole model of presence”, “mental imagery space” is discussed in this study. One hundred participants were involved in the study. Established Presence Questionnaires (PQ) was used to critically appraise the study. The result is discussed in qualitative analysis. As predicted, user's imagery exists as the effect of user's presence in IBVR environment. Results also suggest that the users interact with the IBVR environment through non-symbolic systems, such as the perceptual and the motor system which is similar with the three pole model of presence. Furthermore, this study has important implications for both our understanding of sense of presence exists in IBVR environment even without animation or haptic sensation.
非互动性或低互动性媒体(如广播)可以变得高度身临其境和逼真,为参与者产生一种引人注目的存在感。低交互技术的一个例子是简单的基于图像的虚拟现实(IBVR)环境,它不具有与触觉交互的感知特征,可以提供高用户的存在感。因此,本研究探讨在没有电脑动画的情况下,IBVR环境是否能引起用户的存在感?此外,本研究还探讨了“在场”、“心理意象空间”的三极模型。100名参与者参与了这项研究。采用既定存在问卷(PQ)对研究进行批判性评价。对结果进行了定性分析。正如预测的那样,用户的意象作为用户在IBVR环境中存在的效应而存在。结果还表明,用户通过非符号系统(如感知系统和运动系统)与IBVR环境进行交互,这与在场的三极模型相似。此外,该研究对我们理解在没有动画和触觉的IBVR环境下存在的存在感具有重要意义。

Students' attendance records are important documents for academic institutions that reflect the students' performances and the credibility of the academic institutions. Nevertheless, the process of managing these documents had been done manually, by pen and papers thus making it less efficient. This paper discusses about the development of the new Online Attendance System as the enhancement of the previous developed system named Attendance Register System for higher academic institutions in Malaysia. The new online system is being developed by adapting the concept of the web-based system architecture. The web-based system architecture used in the development of this system involves integration of various open source web-based technologies such as MySQL, PHP and Apache Web Server hence making the Online Attendance System more efficient and cost effective. The development of the Online Attendance System involves four main phases which are the construction of the conceptual framework where the scopes and requirements as well as the target users of the system had been identified, developing the proposed system's architecture by adapting to the web-based architecture, and the construction of the logical design and the physical design. The Online Attendance System consists of automated processes such as able to generate online attendance reports, warning letters and graph charts thus making the processes of recording and reporting the students' attendances more efficient and well-organized.
学生出勤记录是反映学生成绩和学校信誉的重要文件。然而,管理这些文件的过程是用笔和纸手工完成的,因此效率较低。本文讨论了新的在线考勤系统的开发,作为先前开发的系统的改进,称为出勤登记系统在马来西亚的高等院校。新的在线系统是根据基于网络的系统架构的概念开发的。本系统的开发采用基于Web的系统架构,集成了MySQL、PHP、Apache Web Server等多种基于Web的开源技术,使在线考勤系统更加高效、经济。在线考勤系统的开发主要包括四个阶段:确定系统的范围、需求和目标用户的概念框架的构建;适应基于web的体系结构的系统架构的开发;逻辑设计和物理设计的构建。在线考勤系统由自动化流程组成,例如能够生成在线考勤报告,警告信和图表,从而使学生的考勤记录和报告过程更加高效和有序。

Software measurement can play a major role in ensuring the quality and reliability of software products. The measurement activities require appropriate tools to collect relevant metric data. Currently, there are several such tools available for software measurement. The main objective of this paper is to discuss the validation of results when using a combination of multiple measurement tools especially for products built using object-oriented techniques and languages. In this paper, we highlight four tools for collecting metric data, in our case from several Java-based open source projects. Our findings show that the tools provide different results for similar metrics and we discuss the methods used to validate the results reported by the tools. Our research is currently based on the work of Card and Glass, who argue that design complexity measures (data complexity and structural complexity) are indicators/predictors of procedural/cyclomatic complexity (decision counts) and errors (discovered from system tests).
软件度量在保证软件产品的质量和可靠性方面起着重要的作用。度量活动需要适当的工具来收集相关的度量数据。目前,有几个这样的工具可用于软件测量。本文的主要目的是讨论当使用多种测量工具的组合时,特别是对于使用面向对象技术和语言构建的产品,结果的验证。在本文中,我们重点介绍了收集度量数据的四种工具,在我们的案例中,这些工具来自几个基于java的开源项目。我们的研究结果表明,这些工具为类似的指标提供了不同的结果,我们讨论了用于验证工具报告的结果的方法。我们的研究目前是基于Card和Glass的工作,他们认为设计复杂性度量(数据复杂性和结构复杂性)是程序/圈复杂性(决策计数)和错误(从系统测试中发现)的指示器/预测器。

An effective e-government platform provides greater access to government services among citizens, businesses, and tourists. However, most e-government portals are not integrated as each government agency has its own portal. This may cause confusion and becomes a cumbersome task among stakeholders. This paper proposes a one-stop e-government architecture that integrates one-stop portal, e-government service application, and e-government service provider. The architecture provides seamless interoperability of e-government services among different government agencies. This work exploits various Web technologies and service oriented architecture approaches such as Web portal, portlet, service component architecture, Web services, and BPEL. Finally, this work presents the proof-of-concept of the proposed architecture and a case study in an e-government service environment.
一个有效的电子政务平台可以为公民、企业和游客提供更多的政府服务。然而,由于每个政府机构都有自己的门户,大多数电子政务门户都没有集成。这可能会引起混乱,并成为涉众之间的繁琐任务。本文提出了一个集一站式门户、电子政务服务应用和电子政务服务提供商为一体的一站式电子政务体系结构。该体系结构提供了不同政府机构之间电子政务服务的无缝互操作性。这项工作利用了各种Web技术和面向服务的体系结构方法,如Web门户、portlet、服务组件体系结构、Web服务和BPEL。最后,本文提出了所建议的体系结构的概念验证和电子政务服务环境中的一个案例研究。

The Open Source Software (OSS) philosophy has revolutionized the world of software usage and development by opening the codes. It was accompanied with a number of freedoms that definitely leads to a continuous enhancement and advancement in these software. At the same time, a benefit of this philosophy is that its adoption implies a reduction of software piracy and, in a few decades, perhaps the near extinction of this crime. Furthermore, the evaluation of adoption of OSS by different companies remains a fuzzy one as the most common approach is the use of questionnaires for a survey. In this paper, an automated methodology is proposed so as to evaluate the level of OSS adoption by online businesses. We also demonstrated how network protocols can be used as fingerprints to determine the penetration level of OSS in public hosts. The study was conducted on the public network underlying Mauritius and revealed the extent to which OSS is adopted. The methodology used can be applied to other territories for a similar assessment.
开源软件(OSS)理念通过开放代码彻底改变了软件使用和开发的世界。它伴随着一些自由,这肯定会导致这些软件的不断增强和进步。与此同时,这种理念的一个好处是,它的采用意味着软件盗版的减少,并且在几十年内,这种犯罪行为可能会接近灭绝。此外,对不同公司采用OSS的评估仍然是模糊的,因为最常见的方法是使用问卷进行调查。在本文中,提出了一种自动化的方法来评估在线企业采用OSS的水平。我们还演示了如何使用网络协议作为指纹来确定OSS在公共主机中的渗透级别。这项研究是在毛里求斯基础的公共网络上进行的,并揭示了采用开源软件的程度。所使用的方法可适用于其他领土进行类似的评估。

The embedding of Arabic characters in QR code 在QR码中嵌入阿拉伯字符
Pub Date : 2012-10-01 DOI: 10.1109/ICOS.2012.6417626
M. Kamil, K. A. Jalil
Since the introduction of QR Codes in the 90's, many companies have developed QR Code generators and mobile applications to read QR Codes. Despite the obvious benefits of next-generation data transfers, they have yet to be widely accepted and practiced. One of the main reasons is the use of unique language characters such as Arabic characters, Japanese Kanji, Thai Abugida and so forth. An attempt at embedding Arabic characters into QR Code for example, will result in the character's Unicode representation to be automatically encoded and/or decoded by default, instead of the original alphabet as a result of a method called Romanization. Thus, the intended use of the generated code has been useless. It is also noted that Romanization causes each character to be encoded in its own unique codeword which devours more space than encoding it with codeword for character combinations. In order to help solve this problem, this paper proposes the use of an algorithm that compares each word from an Arabic input with an internal codeword library that will then select the shortest codeword possible for single character and two-character combinations to replace the default Unicode representation, which also serves as a space saving method that allows longer messages to be encoded in a single QR Code. In return, the same method is also used to properly decode the message.
自上世纪90年代引入二维码以来,许多公司开发了二维码生成器和移动应用程序来读取二维码。尽管下一代数据传输有明显的好处,但它们尚未被广泛接受和实践。其中一个主要原因是使用独特的语言字符,如阿拉伯字符、日本汉字、泰国汉字等。例如,在QR码中嵌入阿拉伯字符的尝试将导致字符的Unicode表示在默认情况下被自动编码和/或解码,而不是原始字母(由于一种称为罗马化的方法)。因此,生成的代码的预期用途是无用的。还需要注意的是,罗马化导致每个字符在其自己独特的码字中进行编码,这比使用字符组合的码字进行编码消耗更多的空间。为了帮助解决这个问题,本文提出使用一种算法,该算法将阿拉伯语输入的每个单词与内部码字库进行比较,然后为单字符和双字符组合选择最短的码字,以取代默认的Unicode表示,这也是一种节省空间的方法,允许将较长的消息编码在单个QR码中。作为回报,同样的方法也用于正确解码消息。

Despite the obvious benefits of next-generation data transfers, they have yet to be widely accepted and practiced. One of the main reasons is the use of unique language characters such as Arabic characters, Japanese Kanji, Thai Abugida and so forth. An attempt at embedding Arabic characters into QR Code for example, will result in the character's Unicode representation to be automatically encoded and/or decoded by default, instead of the original alphabet as a result of a method called Romanization. Thus, the intended use of the generated code has been useless. It is also noted that Romanization causes each character to be encoded in its own unique codeword which devours more space than encoding it with codeword for character combinations. In order to help solve this problem, this paper proposes the use of an algorithm that compares each word from an Arabic input with an internal codeword library that will then select the shortest codeword possible for single character and two-character combinations to replace the default Unicode representation, which also serves as a space saving method that allows longer messages to be encoded in a single QR Code.

The increase in security level due to the use of biometric recognition systems compared to traditional identification systems is helping in the rapid advancement of such systems. The use of Fingerprint or Iris recognition systems is considered to be reliable and accurate. Both systems do have some drawbacks and errors. In order to minimize the error and increase the accuracy, we propose a hybrid system for identification by using both fingerprint recognition and Iris recognition systems. In this paper, the algorithm used for identification for Iris image was based on Ng et al algorithm using Rapid Haar Wavelet Decomposition while the algorithm used for fingerprint identification presented by Porpanomchai et al is based on the Euclidean distance from the bifurcation point to the core point. Both algorithms were modified and then combined for the hybrid system. The simulation results show the improvement in performance of the proposed method and the added advantages of combining both identifications systems.
与传统的身份识别系统相比,生物识别系统的使用提高了安全性,这有助于生物识别系统的快速发展。使用指纹或虹膜识别系统被认为是可靠和准确的。这两种系统都有一些缺点和错误。为了最大限度地减少误差,提高识别精度,我们提出了一种结合指纹识别和虹膜识别的混合识别系统。本文用于虹膜图像识别的算法是基于Ng等人的快速Haar小波分解算法,而Porpanomchai等人用于指纹识别的算法是基于分岔点到核心点的欧氏距离。对这两种算法进行了改进,然后将其组合在一起用于混合系统。仿真结果表明,该方法的性能得到了改善,并且具有两种识别系统相结合的优点。
