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。

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。

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.

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.

This paper explores the development of eLearning technologies as a new tool to implement competency-based curricula in Tanzania medical universities, with a specific focus on Muhimbili University of Health and Allied Sciences (MUHAS). The paper provides the background of eLearning aspects and the early attempt of adopting eLearning in 2006 at MUHAS and its challenges leading to failure, next it presents the strategic re-establishment of eLearning to support the new competency-based curricula introduced in 2009. Finally, the paper discusses the challenges faced along the implementation process and provides an overview of lessons learnt. This paper observes that if used effectively, eLearning can enhance ubiquity, equity and quality in medical education and the development of appropriate skills in the developing countries' medical care systems. The paper suggests that in order to improve the quality of medical education under limited resource settings, universities in developing countries should effectively make use of innovative and emerging technologies which are relevant to their respective environments. A successful implementation of eLearning requires a strategic approach which should be embedded by the university management, academic staff and students. The approach should at least take into account significant issues including pedagogy, ICT infrastructure, appropriate technologies, human resources, eLearning policy, training of faculty and students, integration of eLearning and information literacy into university's curricula and partnerships.
本文探讨了电子学习技术的发展,将其作为在坦桑尼亚医科大学实施基于能力的课程的新工具,特别关注Muhimbili卫生与相关科学大学(MUHAS)。本文介绍了电子学习方面的背景和2006年在MUHAS采用电子学习的早期尝试以及导致失败的挑战,然后介绍了电子学习的战略重建,以支持2009年引入的新的基于能力的课程。最后,本文讨论了实施过程中面临的挑战,并概述了所吸取的经验教训。本文观察到,如果有效使用,电子学习可以提高医学教育的普遍性、公平性和质量,并在发展中国家的医疗保健系统中发展适当的技能。为了在有限的资源环境下提高医学教育的质量,发展中国家的大学应该有效地利用与各自环境相关的创新和新兴技术。电子学习的成功实施需要一种由大学管理层、学术人员和学生共同参与的战略方法。这种方法至少应该考虑到一些重要的问题,包括教学法、ICT基础设施、适当的技术、人力资源、电子学习政策、教师和学生的培训、将电子学习和信息素养整合到大学课程和伙伴关系中。

In this paper, we present an approach to adapt and reuse learning annotations and contexts by describing the process to capitalization and reuse of learning annotations and associated learning contexts. This is to provide to the actor, an appropriate learning which is reviewed or validated previously by others, with similar learning contexts. The modeling and the formalization of learning annotations and learning contexts will allow to define functions for their comparison and their evaluations, in order to reuse them. We propose our method for of measuring similarities allowing to provide learning annotations dedicated to a given and well-defined pedagogical goal. An alignment between the two types of ontology, respectively that of the annotation and that of the context will provide us with a learning based on annotations according to the current context which requires a pertinent criterion of similarity between the learning contexts and the learning annotations.
在本文中,我们通过描述学习注释和相关学习上下文的资本化和重用过程,提出了一种适应和重用学习注释和上下文的方法。这是为了给行动者提供一种适当的学习,这种学习是在类似的学习背景下,由其他人先前审查或验证过的。学习注释和学习上下文的建模和形式化将允许为它们的比较和评估定义函数,以便重用它们。我们提出了测量相似性的方法,允许提供专门针对给定和定义良好的教学目标的学习注释。注解本体和上下文本体这两种本体之间的对齐将为我们提供基于当前上下文的注解学习,这需要在学习上下文和学习注解之间有一个相关的相似性标准。
