In this research, we combined the virtual reality technology and the tale-immersion technology, and constructed the prototype system of fusion reality that combining a virtual space and a real space. Moreover, we were able to clarify the effectiveness of this research. In this research, we constructed the fusion reality environment that used video avatar by background differencing technique, and achieved...
We propose an approach for gathering web pages written in a specific language. The approach consists of a language predictor and a web site crawler. The language predictor is a machine learning based component that can learn from an example host graph some characteristics of relevant hosts, and is used to calculate the language degree of a web server whether it has a high probability to serve web...
It is difficult to discover Walkable Path for a doctor going to the targeted patient basis in the confused calamity spot. Applying a sensor network to an emergency lifesaving system called triage which makes a lifesaving order decision is an active area of research. Although research which saves the energy and the traffic in the case of the information gathering to a sink node is done, they do not...
CAPTCHA is a technique that is used to prevent automatic programs from being able to acquire free e-mail or online service accounts. However, as many researchers have already reported, conventional CAPTCHA could be overcome by state-of-the-art malware since the capabilities of computers are approaching those of humans. Therefore, CAPTCHA should be based on even more advanced human-cognitive-processing...
The multicast routing is very important for Mobile Ad hoc Networks (MANET). Though many multicast routing protocol are proposed, we consider ODMRP, which is a mesh based routing protocol. In ODMRP the reliability of the communication can be maintained by putting the relay nodes in the mesh. However, when the network is overloaded the performance of ODMRP is deteriorated. In this research, we try to...
Agent-systems can bring important benefits especially in applications scenarios where highly distributed, autonomous, intelligence, self-organizing and robust systems are required. Furthermore, high levels of autonomy and self-organization of agent systems provide excellent support for development of systems with high dependability requirements. Two main research areas that fall in this category are...
Nowadays information systems are being shifted to distributed architectures to obtain the benefits like scalability, autonomy, and faulty-tolerance. The peer-to-peer (P2P) model as a fully distributed system, is composed of peer processes (peers) which cooperate with each other to achieve a common goal. Here, peers have to efficiently and flexibly make an agreement on one common value which satisfies...
Module redundancy is often used in the construction of reliable systems. Triple Module Redundancy (TMR) is a method for improving reliability through module redundancy, although it does not give the correct results when two out of three modules fail. We, therefore, proposed a new voting architecture known as Stateful TMR, which uses both the results of TMR and the history of states to select the most...
The integer factoring problem is known as one of the hard problem in cryptology, and some public-key cryptosystems including RSA are designed based of this fact. Recently, several dedicated integer factoring devices have been proposed, however, no implementational or even experimental results are not shown. This paper proposes a novel design of a dedicated integer factoring device. In order to verify...
A new ontology-supported and hybrid recommending information system for scholars was proposed. Not only can it fast integrate specific domain documents, but also it can extract important information from them through the hybrid filtering technology to take information integration and recommendation ranking. The experiment outcomes proved that the reliability and validity measurements of the whole...
A Mobile Ad hoc Network (MANET) is a collection of wireless mobile terminals that are able to dynamically form a temporary network without any aid from fixed infrastructure or centralized administration. In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper,...
Remarkable wireless networks technology developments have made us to expect the realization of new applications like the advanced traffic system, the disaster prevention system, and the adhoc network system. However some of new wireless network services need the network which is never died. In this paper, Never Died Network with the Combination of Cognitive Wireless Network and Satellite System. The...
Tiled display is very effective display device in visualization task. So far, many tiled display systems were proposed with different approaches. However those are not designed as human computer interactive devices for under such environment. The conventional mouse and keyboard devices force burden and confine of user interaction to the master node. In this paper, we propose a wireless input device...
More and more network applications have appeared in recent years. Government, university, industry and individual Internet users and network services need more bandwidth and various network applications. Many new network protocols are proposed so that it is now becoming harder to manage the network. In the conditional network, every network protocol uses the fixed port, the so-called well-known port...
