♠ Corresponding Author: Aaron Alzola Romero Email: [email protected] Cyberspace challenges our traditional cultural understandings of notions as basic as time, space, and—more importantly—identity. With the advent and growth of electronic communication, it is becoming increasingly necessary to ask ourselves who we actually are and who we are interacting with when we are on-line. T...

1. Introduction Relevance or relatedness across speaker utterances is a basic normative ideal of conversation, upon which inter-subjective coherence is said to depend (Grice 1975; Sperber and Wilson 1986). Floutings of relevance are the exceptions that prove the rule, in that they typically signal an underlying coherence that can be derived through cognitive inferencing. Most research on releva...

Internet based virtual reality offers the opportunity to render content in three dimensions. In addition, the Internet provides a medium to support collaborative activities. In this work, we describe how collaborative capabilities are integrated into the Interactive Land use VRML Application (ILUVA). ILUVA is a VRML based application that supports highly interactive functionality, live updates,...

The purpose of this study is to examine the difference between chatting avatars and messenger avatars. Users of IRC are not generally known by their ‘real’ names, while users of IM are usually known by their ‘real’ names: i.e., IRC users are anonymous to each other, whereas those of IM are not. Avatars represent users' identity and desire of self-disclosure. Therefore, we assume that the anonym...

Application-level network relays possess many desirable properties, including support for communication between disconnected clients, increasing bandwidth between distant clients, and enabling routing around Internet failures. One problem not considered by existing systems is how to assign client load to relay servers in order to maximize throughput of the relay-system. In this paper, we are in...

We study the interference channel with a signal cognitive relay. A signal cognitive relay knows the transmit signals (but not the messages) of the sources non-causally, and tries to help them communicating with their respective destinations. We derive upper bounds and provide achievable schemes for this channel. These upper and lower bounds are shown to be tight from generalized degrees of free...

Data is the primary concern in data mining. Data Stream Mining is gaining a lot of practical significance with the huge online data generated from Sensors, Internet Relay Chats, Twitter, Facebook, Online Bank or ATM Transactions. The primary constraint in finding the frequent patterns in data streams is to perform only one time scan of the data with limited memory and requires less processing t...

Text message stream which is produced by Instant Messager and Internet Relay Chat poses interesting and challenging problems for information technologies. It is beneficial to extract the conversations in this kind of chatting message stream for information management and knowledge finding. However, the data in text message stream are usually very short and incomplete, and it requires efficiency...

This study explored the extent to which student emotion management factors and normative orientation (belief that chat rooms have normative standards of conduct similar to face-to-face interaction) circumscribe the sending of hostile messages within electronic relay chat rooms on the Internet. A questionnaire survey collected data from 114 undergraduate and graduate students from a large univer...

Near Field Communication (NFC) is a short-range contactless communication standard recently emerging as cashless payment technology. However, NFC has been proved vulnerable to several threats, such as eavesdropping, data modification, and relay attacks. A relay attack forwards the entire wireless communication, thus communicating over larger distances. In this paper, we review and discuss feasi...
