Abstract 

With the tremendous advancements in technology and the Internet, data security has become a major issue around the globe. To guarantee that data is protected and does not go to an unintended endpoint, the art of data hiding (steganography) emerged. Steganography is the art of hiding information such that it is not detectable to the naked eye. Various techniques have been proposed for hiding a secret message in a carrier document. In this paper, we present a novel design that applies Reed-Solomon (RS) error correcting codes in steganographic applications. The model works by substituting the redundant RS codes with the steganographic message. The experimental results show that the proposed design is satisfactory with the percentage of decoded information 100% and percentage of decoded secret message 97. 36%. The proposed model proved that it could be applied in various steganographic applications.

For the past decade, 3D printing (3DP) has become popular due to availability of low-cost 3D printers such as RepRap and Fab@Home; and better software, which offers a broad range of manufacturing platform that enables users to create customizable products. 3DP offers everybody with the power to convert a digital design into a three dimensional physical object. While the application of 3DP in developing countries is still at an early stage, the technology application promises vast solutions to existing problems. This paper presents a critical review of the current state of art of 3DP with a particular focus on developing countries. Moreover, it discusses the challenges, opportunities and future insights of 3DP in developing countries. This paper will serve as a basis for discussion and further research on this area.

Abstract

The main delivery system in Tanzanian education has been face-to-face approach relying on printed educational materials. High cost of books and insufficient teaching materials are still the major challenges. Recently, Online Social Networks (OSN) have gained popularity across the world and they are used for sharing information, news, chatting, messaging, and keeping in touch with friends. Studies have shown that OSNs can be used as tools for facilitating learning, supplementing face-to-face approach. Currently, there is an increase in the number of local OSN sites and subscribers in Tanzania. This paper examines to what extent are local OSNs in Tanzania exploited as e-learning platforms. Moreover, it addresses the student’s perceived challenges and discusses the opportunities of using local OSNs towards fostering students' academic development
