moving toward third millennium is characterized by capabilities in transforming human life. specially, development of information technologies in everyday life lead to great changes in communication tools andour current understanding ofurban social life. indeed, telecommunications because of independency from time—space constraints, provide a new unlimited space for social interactions in globa...

Cyber graphics as an emerging technology has been playing key roles as human interfaces of cyber worlds. With the ever increasing roles of cyber worlds in the real world, as seen in e-financial trading that deals GDP-equivalent in a day, understanding of cyber graphics is becoming essential. To this end, scientific research has been conducted to grasp the foundation as invariants. Cellular mode...

Humans consciously and subconsciously establish various links, emerge semantic images and reason in mind, learn linking effect and rules, select linked individuals to interact, and form closed loops through links while co-experiencing in multiple spaces in lifetime. Machines are limited in these abilities although various graph-based models have been used to link resources in the cyber space. T...

It is well known that the metaverse, also named general cyberspace (GC), virtual-real fusion spaces, consisting of a virtual space, namely, and cyber-enabled physical, social, thinking (cyber-enabled) spaces. This article discusses open issues metaverse in terms science technology proposes new discipline interdiscipline hierarchy for cyberology first. Then, it explores various relevant standard...

Ubiquitous computing is resulting in a proliferation of cyber-physical systems that host or manage valuable physical and digital assets. These assets can be harmed by malicious agents through both cyber-enabled or physically-enabled attacks, particularly ones that exploit the often ignored interplay between the cyber and physical world. The explicit representation of spatial topology is key to ...

Recognition, reasoning and retrieval are three fundamental operations in a cyber-physical space that is capable of identifying and tracking the movements of people and answering questions about their whereabouts. We show that a state transition system effectively abstracts the three R’s: events abstract recognition, transition function abstracts the reasoning, and states abstract the informatio...

Critical infrastructures rely on cyber and physical components that are both subject to natural, incidental or intentional degradations. Game theory has been used in studying the strategic interactions between attackers and defenders for critical infrastructure protection, but has not been extensively used in complex cyber-physical networks. This paper fills the gap by modeling the probabilitie...
