Recently computer can make cyberspace to walk through by an interactive virtual reality technique. An avatar in cyberspace can bring us a virtual face-to-face communication environment. In this paper, we realize an avatar which has a real face in cyberspace to construct a multi-user -communication system by voice transmission through network. Voice from microphone is transmitted and analyzed, t...

Rigid cyberspace defenses are proving unable to meet advanced and modern cyberspace threats. As a result, there has been increasing focus and interest in cyber resiliency, but what will it take to be resilient in future cyber combat? We can glean some useful concepts from the ancient Japanese proverb about the resiliency of bamboo in a storm. In comparison with the massive oak, which relies on ...

INTRODUCTION Over the past few decades, two revolutionary approaches have emerged as a new form of medical education: Electronic Medical Education and Web-based Medical Education. A number of well-known medical institutions, such as Harvard and Johns Hopkins used a wide range of cyberspace capabilities to increase their competitiveness. Researchers have expressed that cyberspace will change hea...

Various spatial metaphors related to cyberspace suffer from two major deŽ ciencies. First, they do not take into account that cyberspace is not a preexistent territory, but an entity that emerges in the process of its development. Second, cyberspace is not a metric space, so that most of the ready-made constructs, like the topologic spaces, cannot be of much use. An interpretation of Blake’s wo...

Cyberspace operations are dependent upon highly sophisticated technology. Unfortunately, it is challenging to find or develop solutions that successfully support critical processes and decisions. Innovation, and the resources associated with innovation, appear to focus primarily on the technology with little emphasis on the human factors associated with employment, training, and sustainment of ...

With the moving development of networks, especially Internet of Things, electronic identity administration in cyberspace is becoming more and more important. And personal identity management in cyberspace associated with individuals in reality has been one significant and urgent task for the further development of information construction in China. So this paper presents a RFID-based electronic...

The existing border-less cyberspace is mainly the result of the open network architecture of IPv4. This structure does not obey principles of territorial jurisdiction of states. The Yahoo! case demonstrates needs of states and existing limits of IPv4. IPv6 offers extensive geographic tracking allowing a nationalisation of cyberspace. In the future, content filtering may be replaced by blocking ...

The Department of Defense Strategy for Operating in Cyberspace (DSCOC) calls out the need for active cyber defense (ACD). The function of ACD is to provide sensing, sense-making, decision-making, and acting in cyber-relevant time in order to provide cyberspace defense before an adversary is able to bring about their desired effect. As automation increases and we move ever closer to automated cy...

F rancis Bacon is reported to have said that the three things that made his world different from that of the ancient Greeks and Romans were the printing press, the compass and gunpowder. It is instructive to note he didn’t mention the water pump, the rigid horse collar, or lateen sails—all of which were critical to the advancement of agriculture and commerce. One suspects Bacon was not interest...
