This paper provides the semantics and axiomatization of propositional attitudes relevant to the critical thinking activity. This axiomatization can be used to provide a common ground for reasoning with different resources for the purpose of representing and analysing their points of view about particular issues. It can also be used during interaction with other (possibly human) agents in order to...
Constructing an effective evaluation model is an important mission for distance education workers. Based on the features and requirements of Web-education, this paper designs a teaching evaluation model for the deaf on Web-based distance education. This paper is aimed to introduce the model, and introduces it on the aspects of Web-teachingpsila features and evaluation process.
Due to their unique electrical, thermal, and mechanical properties, single wall carbon nanotubes (SWCNTs) have attracted considerable interest for use in a number of applications such as lithium ion batteries, fuel cells, and conductive wiring. However, the energy required to synthesize and purify SWCNTs in the manufacturing phase must be considered in order to fully realize the benefits in the use...

Phishing scams have become a problem for online banking and e-commerce users. There are different proposed anti-Phishing approaches that make users aware of Phishing emails and Websites. This paper evaluates the anti-Phishing knowledge retention for users. It compares the retention of the users' of a novel anti-Phishing approach previously proposed with the retention of the users of the approach of...
Information and Communications Technology(ICT) has been widely adopted by higher education institutions (HEIs) in the UK to for example provide greater access for different target learners and become vehicles for enriched pedagogical experiences. Many studies have discussed the great impact of ICT on teaching and learning and the changes it can bring. However, as revealed in literature as well as...
Internet, with its vast source of information and new communication technology, has been embraced as an important tool for language teaching. This paper explores how teachers of Business English, a branch of ESP, may make good use of Internet to facilitate teaching. It first specifies the scope of Business English, and explores the resources online that can be employed to optimize the Business English...
This paper introduced the Sakai e-learning platform and blended learning, discussed the design of blended learning based on Sakai according to writerpsilas teaching experiences, including the design of learning resources, the design of learning activities and the design of learning evaluation. We found that Sakai platform can effectively implement the blended learning and greatly improve teaching...
This paper presents a piezo-driven compliant stage implemented by the prismatic-prismatic (PP) compliant joint chains which accomplish a 4-PP compliant guide mechanism for two-DOF translations. The compliant joints consist of circular notch hinges. The 4-PP compliant guide mechanism is driven directly by two stack-type piezoelectric elements. Through design and analysis, the compliant guide mechanism...
The boundary problem of interaction of the monochromatic electromagnetic field which is an unspecified combination of E- and the H-polarized plane electromagnetic waves with a flat slab of a biisotropic material is solved. The method of determination of effective material parameters of the biisotropic composite materials is offered.
In the last few years, several Web-based conference management systems have been developed and used by many international conferences. However, almost all of them were built on stand-alone Web servers. Their fault tolerance, scalability and ability of responding to dispersed users are limited. Aimed at addressing these problems, this paper presents a novel approach for Web-based conference management...
There is an emphasis today throughout many academic programs on developing and sustaining information assurance (IA) programs. While we often refer to such programs collectively as information assurance, they tend to be decidedly different in approach and content depending on many factors. This paper does not attempt to differentiate between such approaches but rather outlines a discovery approach...
Mobile learning, a relatively new concept, has gathered momentum and attracted the interest of educators, researchers, and companies developing learning systems and instructional materials. A principal goal of this study was to develop a suitable system for environmental education via mobile technologies. Students sent text messages using the Short Message Service (SMS), and pictures using the Multimedia...
With the rapid growth of information technology, the e-learning has become a major trend in the computer assisted teaching and learning field. Previously, many researchers put efforts into e-learning system with emphasizing the application of multimedia elements; they often neglected the importance of three crucial elements-personalization, contextual understanding and platform-independent standardized...
This paper considers student participation and how it might be better measured using technology. A review of existing studies precedes the analysis of course data on participation collected through various methods. The study confirms previous findings showing that even crude electronic measures of participation in a course have a direct relationship with the ultimate success of the student. The implications...
Photosensitive materials attract many attention due to their potential application in optical devices such as optical data storage, optical communication, ...[1]. Coumarines and their analogues are well-known for their reversible photoinduced cyclodimerisation properties, leading to cyclobutane-based dimers (scheme) [2]. This equilibrium can be tuned according to the wavelength which is applied, and...
This paper deals with computation of the dielectric constant of BaTiO3 composites according to two computation models. The results showed that the dielectric constant epsiv of materials increases with volume of BaTiO3, which is as same as that reported. At same time, the mediate phase was proved to exist between BaTiO3 and polymer. It indicates that the mediate phase computation model is rational.
In this article we analyse how tacit and explicit knowledge are managed in teams. Tacit knowledge is located in human persons and it can not be described formally as data or any other form while explicit knowledge is public and formal. Our approach is qualitative and we aim to describe the appearance and behaviour of knowledge. We also aim to analyse the difference between tacit and explicit knowledge...
Recently, Phishing attacks have become a serious problem for end-users, online banking and e-commerce websites. Many anti-Phishing approaches have been proposed to detect and prevent Phishing. One of the approaches is the anti-Phishing tips published by many governmental and private organizations to help users detect and prevent the attacks by themselves. There are many different tips. This paper...
