This paper examines the status afforded old age in the Byzantine Empire. Frequently neglected in accounts of state formation or comparative history, this Christian imperial state transformed the moral ordering of the lifecourse. In contrast to both classical Greek and Roman society, old age acquired a distinct moral authority in Byzantine society. This status was not confined to a few members o...

Wormhole attack is considered one of the most threatening security attacks for mobile ad hoc networks (MANET). In a wormhole attack, a tunnel is setup in advance between two colluders. The colluders record packets at one location and forward them through the tunnel to another location in the network. Depending on whether or not the colluders are participating in the network functions, the wormh...

Artists try to understand how we see, sometimes explicitly exploring rules of perspective or color, visual illusions, or iconography, and conversely, scientists who study vision sometimes address the perceptual questions and discoveries raised by the works of art, as we do here.

Cloud computing is an attempt to stretch the operation boundaries dynamically on-demand which is not the case with traditional distributed system. This unprecedented nature of cloud though offers various benefits it also has a downside when it comes to fault tolerance since most of the faults experienced by the cloud are unpredictable and thus Byzantine in nature. Byzantine faults in cloud comp...

the seleucid seals and bullae play a significant role in understanding the administration and social structures of this period. due to the limitations in the seleucids sigillographic study, a wide variety of administrative archives of bullae found from important sites such as qumis, susa, babylon, nippur and kadesh are waiting for the researchers to deal with the bullae’s various aspects. apart...

Cooperative, peer-to-peer (P2P) services—distributed systems consisting of participants from multiple administrative domains (MAD)—must deal with the threat of arbitrary (Byzantine) failures while incentivizing the cooperation of potentially selfish (rational) nodes that such services rely on to function. This paper investigates how to specify conditions (i.e., a solution concept) for rational ...
