    Towards Cost-Sensitive Assessment of Intrusion Response Selection

    In recent years, cost-sensitive intrusion response has gained significant interest mainly due to its emphasis on the balance between potential damage incurred by the intrusion and cost of the response. However, one of the challenges in applying this approach is defining consistent and adaptable measurements of these cost factors on...

    Security of Cloud Computing: Seeing Through the Fog

    Cloud computing is a new computing paradigm for the provisioning, delivery and consumption of IT resources and services on the Internet. This computing paradigm comes with huge benefits such as cost savings, increased resilience and service availability, improved IT operations efficiency and flexibility. However, most research cites security concerns as...

    A Model for Teaching Distributed Computing in a Distance-Based Educational Environment

    Due to the prolific growth in connectivity, the development and implementation of distributed systems receives a lot of attention. Several technologies and languages exist for the development and implementation of such distributed systems; however, teaching students in these new technologies remains a challenge. Even though several models for teaching computer...

    A Miniaturisation Technique for a 1.57542 GHz GPS Patch Antenna

    The primary goal of this paper was to cause resonance, 1.57542 GHz, of a microstrip patch antenna reduced in length by a factor of approximately 21 to 5 mm, thus making the antenna length independent of frequency. The results obtained from the physical test, Section V, were satisfactory in that...

    Effective Integration of SMS Communication Into a Distance Education Accounting Module

    The University of South Africa (Unisa), as a distance education institution, is continuously challenged to lessen the negative impact distance has on students' learning. The effective use of technologies affords distance education institutions with valuable opportunities to enhance teaching and support students' learning. Using online technologies in the context of...

    A Distributed Topology Control Algorithm to Conserve Energy in Heterogeneous Wireless Mesh Networks

    A considerable amount of energy is consumed during transmission and reception of messages in a Wireless Mesh Network (WMN). Reducing per-node transmission power would greatly increase the network lifetime via power conservation in addition to increasing the network capacity via better spatial bandwidth reuse. In this paper, the problem of...

    Growth, Employment And Unemployment In South Africa

    The high rate of unemployment in South Africa stands out in an otherwise vastly improved set of macroeconomic fundamentals compared to the situation in the early 1990s. One might be tempted to argue that by this single indicator alone, government policies such as GEAR have been a failure. This paper...

    A Transdisciplinary Andragogy For Leadership Development In A Postmodern Context

    The paper looks at the complex nature of the postmodern world in which leaders find themselves and questions the appropriateness of the current discipline-based structure of MBA education in terms of its usefulness to develop effective postmodern leaders. What is called for is an approach to problem solving which is...

    A Dynamic Packet Aggregation Scheme for VoIP in Wireless Mesh Networks

    Wireless Mesh Networks (WMNs) based on IEEE 802.11 standard is a new trend in networking combining performance, simplicity and economics suitable for backhaul deployments. However, service providers and carriers understand the cost of making large scale adoption of infant technologies. If WMNs are to compete with existing broadband networks, then...

    Utilizing e-Commerce and M-Commerce Applications to Address the Effect of Global Warming

    The impact of global warming is particularly significant to African countries with growing economies. The process of reducing carbon emissions has the potential to negatively impact emerging economies. However the use of web technologies and mobile technologies may be a way of reducing carbon emission without adversely affecting the economy....
