Introduction In a major international synthesis of 1:1 (one-mobile-device-per-learner) Technology-Enhanced Learning (TEL), Chan et al (2006) foregrounded the notion of seamless learning. The 17 distinguished co-authors defined seamless learning as a learning style where a learner can learn in a variety of scenarios and in which they can switch from one scenario or context (such as formal and in...

Despite the importance of seamless connectivity in ubiquitous computing, research for seamless connectivity is not considered properly. To provide seamless connectivity, this paper proposes intelligent contextaware handoff management scheme and middleware architecture. In this paper, we defined our own profiles about various contexts like user intentions as well as issues of network layer and d...

IEEE 802.11 wireless networks have gained great popularity. However, handoff is always a critical issue in this area. In this paper, we propose a novel seamless handoff mechanism for IEEE 802.11 wireless networks which support IEEE 802.11i security standard. Our approach consists of a Dynamic Tunnel Establishing procedure and a seamless handoff mechanism. Dynamic Tunnel Establishing is for each...

The feature of continuous interaction in pen-based system is critically significant. Seamless mode switch can effectively enhance the fluency of interaction. The interface which incorporated the advantages of seamless and continuous operation has the potential of enhancing the efficiency of operation and concentrating the users' attention. In this paper, we present a seamless and continuous ope...

As a new kind of computing paradigm, pervasive computing will meet the requirements of human being that anybody maybe obtain services in anywhere and at anytime, task-oriented seamless migration is one of its applications. Apparently, the function of seamless mobility is suitable for mobile services, such as mobile Web-based learning. In this article, under the banner of seamless mobility, we p...

The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

Texture synthesis through so-called ‘smart copying’ requires a seamless meshing of texture subparts. Current systems first select subparts that seem to globally fit well and then optimise the cut between them on a rather local scale. This order of first selecting patches and then caring about the seamless meshing reduces one’s leeway in the choice of seamless cuts to a small zone of overlap bet...

In this paper, the results of a preliminary performance evaluation of the Seamless parallel processing system are presented. Seamless is a latency tolerant multiprocessor architecture based on RISC processors. Evaluation is performed with a hybrid experimental and simulation based approach utilizing both discrete event simulation and experimentation on an Intel iPSC/860. The results show that c...

A key word describing next-generation wireless communications, so called 4G, is “seamless.” As part of the eJapan Plan promoted by the Japanese Government, the MIRAI (Multimedia Integrated network by Radio Access Innovation) project is aiming at the development of new technologies that will enable seamless integration of various wireless access systems for practical use by 2005. First, this pap...

This paper describes the difficult problem of seamless messaging in heterogeneous communication environments and the design of cooperative agents to address the problem. The seamless messaging agents include coarse-grained agents such as user agents, message transfer agents, server agents (for resources such as speech recognition and generation), application agents (interfacing to mail applicat...
