    3D printing: developing countries perspectives
    (Foundation of Computer Science, 2014) Ishengoma, Fredrick R.; Mtaho, Adam B.
    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.

    The art of data hiding with reed-solomon error correcting codes.
    (Cornell University, 2014) Ishengoma, Fredrick R.
    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.

    Integration of artificial intelligence of things (AIoT) in the public sector: drivers, barriers and future research agenda
    (Emerald, 2022) Ishengoma, Fredrick R.; Shao, Deo; Alexopoulos, Charalampos; Saxena, Stuti; Nikiforova, Anastasija
    Purpose With the development of information technology (IT), governments around the globe are using state-of-the-art IT interfaces to implement the so-called 3E’s in public service delivery, that is, economy, efficiency and effectiveness. Two of these IT interfaces relate to Artificial Intelligence (AI) and Internet of Things (IoT). While AI focuses on providing a “human” garb for computing devices, thereby making them “intelligent” devices, IoT relies on interfaces between sensors and the environment to make “intelligent” decisions. Recently, the convergence of AI and IoT – also referred to as Artificial Intelligence of Things (AIoT) – is seen as a real opportunity to refurbish the public service delivery formats. However, there is limited understanding as to how AIoT could contribute to the improvisation of public service delivery. This study aims to create a modular framework for AIoT in addition to highlighting the drivers and barriers for its integration in the public sector. Design/methodology/approach- This descriptive-explanatory study takes a qualitative approach. It entails a thorough examination of the drivers and barriers of integrating AI and IoT in the public sector. A review of literature has led to the development of a conceptual framework outlining the various factors that contribute to creating public value. Findings- Value creation occurs when AI and IoT coalesce in the public service delivery mechanisms. Originality/value AIoT is a cutting-edge technology revolutionizing health care, agriculture, infrastructure and all other industrial domains. This study adds to the growing body of knowledge on the public sector's use of AI and IoT. Understanding these disruptive technologies is critical to formulating policies and regulations that can maximize the potential benefits for the public-sector organizations.

    Integration of IoT into e-government
    (Emerald, 2023) Shao, Deo; Ishengoma, Fredrick R.; Alexopoulos, Charalampos; Saxena, Stuti; Nikiforova, Anastasija; Matheus, Ricardo
    Purpose The purpose of this paper is to highlight the drivers, barriers, benefits and risks affecting the integration of Internet of Things (IoT) into the e-government and to provide a future research agenda. Design/methodology/approach Existing literature examining the relationships between e-government and IoT is scanned and evaluated by conceptualizing the IoT concept in the e-government perspective. Findings The study shows that there are drivers to integrate IoT in e-government, such as ensuring the economy, efficiency and effectiveness of government operations, which would largely establish a relationship between the government and the citizens. Furthermore, there are barriers to such integration, given the lack of political will, the appropriate information technology infrastructure, the training of the stakeholders with a focus on the employee and the like. Originality/value The integration of IoT in e-government is a novel and weakly explored concept, particularly in the light of new advances such as blockchain in the e-government, which requires further exploration and conceptualization, thereby achieving a shared/common vision and body of knowledge for its further successful and sustainable adoption – to the best of the authors’ knowledge, the current study is one of these initial attempts.

    The potential of blockchain technology in addressing the challenges posed by the COVID-19 pandemic in African developing countries
    (Israa University, 2024) Ishengoma, Fredrick R.
    The objective of this study is to explore the potential of blockchain technology (BCT) in addressing the challenges posed by the COVID-19 pandemic in developing African countries. The study utilizes a thematic analysis approach to analyze data gathered from a focus group discussion (FGD) with experts in the field. The FGD involved researchers and stakeholders with expertise in blockchain technology and healthcare in African developing countries. The data collected from the FGD was transcribed and coded to identify themes and trends related to the use of BCT in the context of the COVID-19 pandemic. The findings shows that BCT can address various COVID-19 challenges in African countries, such as supply chain management, fraud prevention, counterfeit prevention, donation tracking, corruption mitigation, contact tracing, and ensuring clinical data integrity, as indicated by thematic analysis of FGD data. Participants supported BCT's potential to enhance transparency and traceability in healthcare supply chains, ensuring proper distribution of COVID-19 supplies. BCT can combat corruption, bribery, and verify product authenticity to prevent fraudulent or counterfeit distribution. However, implementing BCT effectively requires addressing emerging issues like policy gaps, misinformation, legal concerns, skilled personnel needs, data accuracy, training, cultural barriers, and resource constraints. Blockchain technology shows promise in addressing COVID-19 challenges in African countries by enhancing transparency, traceability, and efficiency in the healthcare supply chain and mitigating corruption and fraud. However, successful implementation requires addressing issues like policy gaps, misinformation, legal hurdles, and resource constraints. Collaborative efforts among policymakers, researchers, and practitioners are vital to harness BCT's potential and improve healthcare quality in African countries during the pandemic.
