Electricity is a power source to run various electronic devices. Problem that often occurs users forget turn off or on their devices, then prepaid and postpaid electricity cannot monitoring the electrical usage of devices in realtime. The designed device overcome these problems has working principle like switch, but there relays several sensors. Controlling can be done by user using main switch...

Internet epidemics are malicious software that can self-propagate across the Internet, i.e., compromise vulnerable hosts and use them to attack other victims. Since the early stage of the Internet, epidemics have caused enormous damages and been a significant security threat. For example, the Morris worm infected 10% of all hosts in the Internet in 1988; the Code Red worm compromised at least 3...

This work aims to classify the language of typed messages in a text chat system used by language learners. A method for training a language classifier from unlabeled data is presented. A dictionary-based method is used to produce initial classification of the messages. Character based n-gram models of order 3 and 5 are built. A method for selectively choosing the n-grams to be modeled is used t...

In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...

BACKGROUND The Internet is of great importance in today's health sector, as most Internet users utilize online functions for health related purposes. Concerning the mental health care sector, little data exist about the Internet use of psychiatric patients. It is the scope of this current study to analyze the quantity and pattern of Internet usage among mental health patients. METHODS Patient...

Asynchronous Transfer Mode (ATM) core networks constitute the backbone of many geographically spread Virtual Private Networks (VPN). The everincreasing implementation of Frame Relay (FR) based VPNs over ATM backbone is leading to a considerable latency in customer services running over the network. This paper describes the process of build-up delay in FR ATM interworking. In addition, this pape...

Much sociolinguistic research discusses differences between male and female language. In this paper we consider the language of Internet Relay Chat (IRC), studying if and how non-standard typography depends on the gender of the writer. We distinguish two kinds of non-standard typography that are typical of IRC users: technology-conditioned and voluntary. Our results show that use of non-standar...
