Abstract:

The purpose of this study was multifold: it aimed to investigate similarities and differences between Chinese and English telephone conversations, to test the validity of the theoretical distinction between transactional talk and interactional talk, and to examine L2 learners' use of the target language. Comparisons along four dimensions were conducted: (1) across languages--Chinese and English, (2) across functions--transactional and interactional talk, (3) across settings--China and the U.S., (4) L1 vs. L2--English as native language and English as a second language. The data consist of natu

Abstract:

Universal service is the focal point of the economic dilemma faced by the telecommunications industry. The advent of competition spurred by several regulatory rulings is forcing rates towards economic costs. It is feared that this movement or the erosion of the toll-to-local subsidy with concomitant increases in local prices severely threatens the concept of universal service. To adequately address these fears, accurate elasticity of demand estimates for telephone access are required. This thesis develops estimates of these demand elasticities for access. These estimates are derived consistent

Abstract:

With the amount of email spam received these days it is hard to imagine that spammers act individually. Nowadays, most of the spam emails have been sent from a collection of compromised machines controlled by some spammers. These compromised computers are often called bots, using which the spammers can send massive volume of spam within a short period of time. The motivation of this work is to understand and analyze the behavior of spammers through a large collection of spam mails. My research examined a the data set collected over a 2.5-year period and developed an algorithm which would give

Thesis (MPhil (Information Science))--University of Stellenbosch, 2009.<br>Mobile telephone subscription in developing countries has increased by more than 500 percent since 2005, with Africa experiencing the highest growth rate globally. Amongst Africa’s 306.5 million subscribers, recorded in 2008, an unexpectedly high adoption rate of the technology by poor, often illiterate rural communities is observed. Mobile telephony generally provides African rural users access to electronic communication for the first time. Providing access to communication, information and knowledge, mobile phon

Abstract:

The languages spoken in developing countries are diverse and most are currently under-resourced from an automatic speech recognition (ASR) perspective. In South Africa alone, 10 of the 11 official languages belong to this category. Given the potential for future applications of speech-based information systems such as spoken dialog system (SDSs) in these countries, the design of minimal ASR audio corpora is an important research area. Specifically, current ASR systems utilise acoustic models to represent acoustic variability, and effective ASR corpus design aims to optimise the amount of rele

Abstract:

Este documento presenta un marco teórico sencillo para analizar el rol del nivel y la incertidumbre del ingreso como determinantes de la demanda de telefonía fija en términos de acceso y uso. En particular se muestra cómo un incremento de la incertidumbre en el ingreso desincentiva el acceso y el uso del servicio de telefonía por parte de los hogares. Además, a manera de ejemplo, se desarrolla un ejercicio de simulación para una población de hogares, los cuales tienen iguales preferencias pero están afectos a una distribución del ingreso.---This document presents a theoretical simple frame to

Abstract:

Automatic object detection is a challenging field which has been evolving over decades. The application areas span many domains such as robotics inspection, medical imaging, military targeting, and reconnaissance. Some of the most concentrated efforts in automatic object detection have been in the military domain, where most of the problems deal with automatic target detection and scene analysis in the outdoors using a variety of sensors. One of the critical problems in Automatic Target Detection (ATD) systems is multiscenario adaptation. Most of the ATD systems developed until today perform u

Abstract:

M.Comm.<br>A modern electronic telephone exchange is very flexible in terms of size. Such exchanges can vary in size from a few lines to more than 50 000 lines. They can be expanded at any time to cater for more subscribers. This means that the telecommunications service provider is able to build the exchange just large enough to supply service to the subscribers in the area, and then expand the exchange on a regular basis as needed to cater for any growth in demand for exchange connections. The main advantage of this flexible approach is that money is not tied up in very expensive exchange eq
