The objective of this study was to assess the influence of some socioeconomic characteristics on purposes for which mobile phone was used by small scale farmers in the Gezira State, Sudan. The total number of small- scale farmers in the State for 2013-2014 growing season was estimated to be 5000. Ten percent of the population was used using the simple random sampling technique. The collected da...

An automobile anti-theft and alarm system based on MCU and information fusion is introduced in this paper, in which multi sensors are used to collect the information about automobile’s situation firstly, and a MCU is used as the central processing and control center, the FCM and the neural network algorithms are adopted to fuse the multisensor information respectively, finally, the automobile’s...

The paper presents an approach for developing composite telecommunication services running on mobile phones which takes advantage of the use of model driven techniques as well as the loose coupling paradigm in SOA. A domain-specific UML dialect named SPATEL has been developed which serves as the basis for generating applications that can be deployed in distinct terminals and servers technologie...

In Europe and North America, the most widely used stream cipher to ensure privacy and confidentiality of conversations in GSM mobile phones is the A5/1. In this paper, we present a new attack on the A5/1 stream cipher with an average time complexity of 2, which is much less than the brute-force attack with a complexity of 2. The attack has a 100% success rate and requires about 5.65GB storage. ...

In Europe and North America, the most widely used stream cipher to ensure privacy and confidentiality of conversations in GSM mobile phones is the A5/1. In this paper, we present an improved guess-and-determine attack on the A5/1 stream cipher with an average time complexity of 248.5, which is much less than any known guessand-determine attack. The attack has a 100% success rate and requires a ...

Recently a technique for transacting goods using GSM mobile phones has become very popular. We present a formal model of these novel transactions using a views based modeling technique. We show how to express two safety properties namely goods and money atomicity within this model using a sub-logic of CTL. By automatically generating a labelled transition system from our views model we can mode...

This project is based on the ongoing data collection campaign by Nokia Research Center-Lausanne. We use location data sampled everyday by mobile phones in the campaign to estimate position of the participants. It is with emerging mobile systems that combines different sensors in a mobile phone so, we can merge different information sources to improve our estimations. Positioning is a problem en...

1. I TRODUCTIO UMS can be described as a system that allows for communication between users via a number of communication technologies over heterogeneous network infrastructures[1]. It integrates networking technologies such as Ethernet, ATM, IEEE 802.11, GSM and UMTS alongwith various devices such as laptops, tablet PCs, desktops, mobile phones, smartphones, PDAs, fax machines and landline pho...

the study was carried out in anambra state, nigeria. questionnaire was used to collect data from a sample of one hundred and eight (108) small-scale farmers. percentage, mean score, standard deviation and factor analysis were used for data analysis. the duration of the study was june 2009 and march, 2010. results of the study indicated that the major constraints to effective use of icts by smal...

Many Social Network Services (SNSs) such as Facebook and MySpace rely on a web server that enables the communication between users. As a consequence, SNSs’ users require Internet access to participate and interact with their contacts, a service that is not usually available in rural and developing areas. In this paper we introduce Goose, a distributed SNS for developing regions which provides s...
