The emerging trends of hybrid e-learning and web 2.0 technologies are a byproduct of the unprecedented advancements of information technology. Understanding and experimenting on how technology fits into the complex realities of classrooms has resulted in significant shifts in learning trends towards a more web based environment as opposed to the previous general teacher-student environment. The education sector in Saudi Arabia has seen massive progress in the past decades with specific efforts put into educating the female population to empower women. Prince Mohammad Bin Fahd University (PMU), a newly established not-for-profit university licensed by the Ministry of Higher Education, having a campus specifically dedicated to female students has been chosen for case study. This research is an attempt to understand the benefits and challenges of implementing hybrid e-learning and web 2.0 application based environment to educate female students. Results of the investigation prove that introducing such learning environments can have significant impacts on improvement of students' evaluation process, research capabilities, and communication skills. Finally, we show how this technology can also yield similar successful results in other countries and other institutes.
混合电子学习和web 2.0技术的新兴趋势是信息技术空前进步的副产品。理解和实验技术如何适应教室的复杂现实,已经导致了学习趋势的重大转变,朝着更基于网络的环境发展,而不是以前的一般师生环境。在过去的几十年里,沙特阿拉伯的教育部门取得了巨大的进步,在教育女性人口以赋予女性权力方面做出了具体努力。穆罕默德·本·法赫德王子大学(PMU)是一所新成立的非营利性大学,获得了高等教育部的许可,该校有一个专门为女学生开设的校园,被选为案例研究对象。本研究旨在了解实施电子学习与web 2.0应用环境相结合的女生教育的好处与挑战。调查结果证明,引入这样的学习环境对提高学生的评价过程、研究能力和沟通能力有显著的影响。最后,我们展示了这项技术如何在其他国家和其他研究所也能产生类似的成功结果。

Nowadays, the impact of technology on education has been outstanding and this brings new challenges for educational institutions to manage many issues that were previously not managed with ease due to geographical limitations or lack of adequate training technologies. The extensive use of technology in learning makes its use inevitable in the assessment process. Although, a lot of software packages exist in the market, it is difficult to adapt them according to a certain educational system. In this paper we present the characteristics of the new model of e-testing system that we have designed and developed. This system is implemented and is used for testing by several schools of our country. Before applying the new system, students were tested in a classical way. We have gathered and compared the classical testing results and those from using e-testing tool for assessment of student knowledge. As a conclusion, the success of the students tested electronically is much higher comparing with the success of students tested classically.
如今,技术对教育的影响已经突出,这给教育机构带来了新的挑战,因为以前由于地理限制或缺乏足够的培训技术而无法轻松管理的许多问题。技术在学习中的广泛应用使其在评估过程中的应用成为必然。虽然市场上有很多软件包,但很难根据一定的教育体系来适应它们。本文介绍了我们设计开发的新型电子测试系统的特点。该系统已在国内多所学校实施并进行了测试。在应用新系统之前,学生们以传统的方式进行测试。我们收集并比较了经典测试结果和使用电子测试工具进行学生知识评估的结果。综上所述,电子测试的学生比传统测试的学生成功得多。

In this paper, we expose a successful approach of a course project aiming to improve technical skills of engineering students by encouraging them to use common software tools and developing experimental platforms. The course is dedicated to advanced undergraduate control engineering students. Only two experimental platforms, among twenty projects, developed by the students as part of the course are exposed. The two projects use LabVIEW programming environment, its data acquisition platform and a wide-ranging set of tools for analyzing, displaying and storing data. The main objective of such education approach is to produce qualified engineers who are ready for innovation in research and industry careers, able to share results and collaborate with international projects. Recruitment results have shown that employers have more confidence in the technical abilities of our students for creating new business opportunities which could enhance their recruitment criteria.

Laboratory exercises are a basic premise of quality experience in the practical education of biomedical engineering specialists and physicians. An increasing number of students and reorganized curricula require innovative approaches to laboratory experiments. Four laboratory exercises have been defined and added into the syllabus of the course, “Models in Biomedical Engineering”. They include system identification on example of mechanical ventilation, feedback control in biological systems, signal models on example of blood pressure and flow velocity for assessment of cerebral autoregulation, and process models on example of pacemaker therapy. These complex topics were implemented to an e-learning project in order to enhance and simplify learning. Using the authoring tool IDEA an e-learning tutorial could achieve this goal. Online tutorials composed of structured theory explanation, interactive exercises and tests allowed students to learn according to their pace and time. So the tutor could concentrate on those topics, which were problematic for the students, comprehensive user tracking was successfully utilized.
实验练习是生物医学工程专家和医师实践教育中获得高质量经验的基本前提。越来越多的学生和重组的课程需要创新的方法来进行实验室实验。四项实验练习已被定义并添加到“生物医学工程模型”课程的教学大纲中。它们包括以机械通气为例的系统识别,生物系统中的反馈控制,以血压和血流速度为例的信号模型,用于评估大脑自动调节,以及以起搏器治疗为例的过程模型。这些复杂的主题被应用到一个电子学习项目中,以加强和简化学习。使用创作工具IDEA制作电子学习教程可以实现这一目标。由结构化理论讲解、互动练习和测试组成的在线教程允许学生根据自己的节奏和时间学习。这样导师就可以集中精力在学生比较难的话题上,成功地利用了全面的用户跟踪。

Code division multiple access (CDMA) systems are being counted to provide the necessary infrastructure to implement future 3G systems. The CDMA is uniquely featured by its spread spectrum (a random) process employing a pseudo random noise (PN) sequence, thus it is called the spread spectrum multiple access (SSMA). The CDMA can eliminate the data transfer latency variations by sharing the data communication media among multiple users concurrently. In this proposed work, we simulate the functionality of CDMA system on Xilinx ISE platform. Here, we use Manchester encode/decode technique for encryption and decryption. The simulation results show the working of CDMA transmitter and receiver on Verilog platform. Implementation of proposed system is targeted on Virtex 5 FPGA.
码分多址(CDMA)系统正在为实施未来的3G系统提供必要的基础设施。CDMA的独特之处在于其扩频(随机)过程采用伪随机噪声(PN)序列,因此被称为扩频多址(SSMA)。CDMA通过在多个用户之间同时共享数据通信介质,消除了数据传输延迟的变化。在本文中,我们在赛灵思ISE平台上模拟了CDMA系统的功能。在这里,我们使用曼彻斯特编码/解码技术进行加密和解密。仿真结果表明,CDMA发射机和接收机在Verilog平台上工作正常。该系统是在Virtex 5 FPGA上实现的。

E-learning has been quite prevailing both in academia and industry. The development of e-learning models is not only addressing the concerns of the learner but also a technological challenge. There must be a business collaborating mechanism in learning process to ensure efficient and effective accomplishment of the learning activities. This paper presents a novel approach to map the collaborating mechanism into an e-learning application which uses the web services technology with a timing constraints specification. Our efforts concentrate on proposing a conceptual framework to conspicuously help designer in the optimizing the e-learning process through a robust comprehension of collaboration relationship between learning objects. Thanks to the transformation of framework to Hierarchical Timed Predicate Petri-Nets model, desirable properties such as deadlock free and safe as well as timing constraints satisfiability can be easily checked by designer.

Along with the changes in the realm of language teaching and learning in 1960s from the previous teacher-centered methodologies and the subsequent emergence of social-constructivist approaches, learners came to be considered as the key in the field. As a result, learner-centered approaches were developed and special attention was given to sociological dimensions of second language learning. Due to these shifts of focus, concept of learner identity came to attract the attention of language teachers and scholars. Therefore, second language scholars tried to investigate the possible relationship between the language learner and the larger social world. In the same line, the present article attempts to represent a description of the main variables in relation to learner identity aimed at shedding light on comprehending the theoretical points significant in the field. Then, the article goes on to discuss the role of identity and its possible influences in the field of second language teaching and learning. Finally, the applications in the field are discussed.
随着20世纪60年代以教师为中心的教学方法在语言教学领域的变化和随后出现的社会建构主义方法,学习者开始被认为是这一领域的关键。因此,以学习者为中心的研究方法得到了发展,并特别关注第二语言学习的社会学维度。由于这些焦点的转移,学习者身份的概念开始引起语言教师和学者的关注。因此,第二语言学者试图研究语言学习者与更大的社会世界之间可能存在的关系。在同一条线上,本文试图描述与学习者身份相关的主要变量,旨在阐明理解该领域重要的理论观点。接着,本文探讨了认同在第二语言教学中的作用及其可能产生的影响。最后,讨论了该方法在该领域的应用。

The current demand growth of new components capable of operating at high power, high frequency, high temperatures and convergence towards miniaturization has lead to the development of new fields of nanotechnology based on II-VI semiconductor. Interest in nanostructures based on II-VI semiconductor narrow gap containing mercury (such as superlattices HgTe / CdTe) was due to their advantages over alloys with cadmium telluride Mercury (MCT: HgCdTe). The ternary alloy Hg1−xCdxTe is a semiconductor band-gap direct, In our work we are interested in the ternary compound Hg07Cd03Te. The results obtained are very satisfactory; they are compared with experimental results, and are in good agreement. These results are very promising and open new perspectives for the realization of solar cells and applications in the field of sensors. In this paper an analytical modeling of p+-HgCdTe/n-HgCdTe/CdZnTe, homojunction photodetector for long wavelength free space optical communication has been reported. The results obtained on the basis of analytical model have been compared and contrasted with the simulated results using ATLASTM. The photodetector has been studied in respect of energy band diagram, electric field profile, doping profile, dark current, resistance area-product, quantum efficiency, spectral response, responsivity and detectivity by analytical method using closed form equations and also been simulated by using device simulation software ATLASTM from SILVACO international.

Anomaly detection in geographic routing protocols 地理路由协议中的异常检测

Providing security for sensor nodes is one of the important issues in WSNs because they are deployed in the harsh environment. WSNs are distributed in nature and preparing centralized security solutions cannot be a suitable for WSNs. There are various sensor holes that may be formed in WSNs and create variations in network topologies and also threaten the upper layer applications such as sinkhole, black holes, wormholes and Sybil attack. Wormhole attack occur when two or more malicious nodes receive packets at one point of the network and transmit them to another malicious node by a wired or wireless tunnel; wormhole is carried out easily without requiring compromising sensor nodes in the network. Also, the wormhole attack may cause other type of attacks like DoS or Sybil attack. Using a cryptographic technique is not enough to prevent wormhole attack. In this study, a new scheme is proposed based on modifying the forwarding packet process, selecting the best neighbour and using hop count technique in order to prevent and detect wormhole and thus, reduce the number of untrusted packets in geographic routing protocols.

由于传感器网络部署在恶劣环境中,为传感器节点提供安全保障是传感器网络的重要问题之一。无线传感器网络本质上是分布式的,集中式的安全解决方案不适合无线传感器网络。在无线传感器网络中可能会形成各种传感器孔,并造成网络拓扑结构的变化,同时也会威胁到上层应用,如天坑、黑洞、虫洞和Sybil攻击。虫洞攻击发生在两个或多个恶意节点在网络的一点接收数据包,并通过有线或无线隧道将其传输到另一个恶意节点;虫洞很容易实现,而不需要损害网络中的传感器节点。此外,虫洞攻击可能导致其他类型的攻击,如DoS或Sybil攻击。使用加密技术不足以防止虫洞攻击。本文提出了一种基于修改报文转发过程、选择最佳邻居和使用跳数技术的新方案,以防止和检测虫洞,从而减少地理路由协议中不可信报文的数量。利用数学建模和仿真对所提方案进行了性能评估。结果与节点认证方案(ANS)和反向路由方案(RRS)等相关研究成果进行了比较。

WSNs are distributed in nature and preparing centralized security solutions cannot be a suitable for WSNs. There are various sensor holes that may be formed in WSNs and create variations in network topologies and also threaten the upper layer applications such as sinkhole, black holes, wormholes and Sybil attack. Wormhole attack occur when two or more malicious nodes receive packets at one point of the network and transmit them to another malicious node by a wired or wireless tunnel; wormhole is carried out easily without requiring compromising sensor nodes in the network. Also, the wormhole attack may cause other type of attacks like DoS or Sybil attack. Using a cryptographic technique is not enough to prevent wormhole attack. In this study, a new scheme is proposed based on modifying the forwarding packet process, selecting the best neighbour and using hop count technique in order to prevent and detect wormhole and thus, reduce the number of untrusted packets in geographic routing protocols.

In the past decade, a number of adaptive hypermedia learning systems have been developed. However, most of these systems tailor presentation content and navigational support solely according to students' prior knowledge. On the other hand, previous research suggested that learning styles significantly affect student learning because they refer to how learners process and organize information. To this end, this paper presents an approach to integrate learning styles into adaptive e-learning hypermedia. The main objectives were to develop a Learning Style based Adaptive E-learning Hypermedia System (LS-AEHS) and assess the effect of adapting educational materials individualized to the student's learning style. In this work, our main goal aims to adopting the theory of experiential learning in the context of the DAVID KOLB's model to pass of this learning style model to define the adaptation rules in order to adapt the learning content and the navigation to each learning style in KOLB model. To achieve the main objectives, a case study was developed. An experimental evaluation was designed to evaluate the new approach of matching learning materials with learning styles and their influence on student's learning achievement. The findings support the use of learning styles as guideline for adaptation into the adaptive e-learning hypermedia systems.
在过去的十年中,许多自适应超媒体学习系统已经被开发出来。然而,这些系统中的大多数都是根据学生的先验知识来定制演示内容和导航支持。另一方面,先前的研究表明,学习风格显著影响学生的学习,因为他们是指学习者如何处理和组织信息。为此,本文提出了一种将学习风格融入自适应电子学习超媒体的方法。主要目标是开发一个基于学习风格的自适应电子学习超媒体系统(LS-AEHS),并评估个性化教材适应学生学习风格的效果。在这项工作中,我们的主要目标是采用DAVID KOLB模型背景下的体验学习理论,通过这种学习风格模型来定义适应规则,从而使学习内容和导航适应KOLB模型中的每种学习风格。为了实现主要目标,进行了案例研究。本文设计了一项实验评估,以评估学习材料与学习风格匹配的新方法及其对学生学习成绩的影响。研究结果支持使用学习风格作为适应自适应电子学习超媒体系统的指导方针。
