In the modern world of telecommunication, the application of the internet was expected to fill in the gap but the gap persists. With all the effort made by world forums, it was expected to have no more problems related to AT accessibility, and cost. This study, therefore, analysed the requirement needed for the development of a reliable web-based forum that could provide a consistent linkage between AT consumers, donors, and vendors for ease of AT accessibility at affordable cost in Tanzania. The study was qualitative and employed questionnaires, observation, and interview methods to collect data from a total of 207 respondents who were purposefully selected, of whom 200 were AT consumers, 5 AT donors, and 2 vendors. Microsoft forms were used to analyze data and the presentation was done descriptively. The study disclosed nine requirements for the development of a web-based forum including location, product description, means of payment and goods transportation, time of delivering goods, types of disability, kind and quantity of AT, means of payment, and price. Having all that information centerd at one site will ensure a constant availability of AT and AT accessibility information among donors, vendors and consumers of AT in Tanzania.</p> Josephine C.

The study employs a quantitative approach and evaluates the performance of different classification algorithms using metrics such as precision, recall, F1-score, and AUC. The population for this study is all publicly available datasets for NLP classification, and the data is collected using open-source NLP tools. The study shows that certain classification algorithms such as Random Forest, Decision Trees, Naive Bayes, SVM, or Neural Networks perform better than others in terms of both runtime and accuracy. However, some algorithms are faster but less accurate, while others are slower but more accurate. The analysis provided insights into how the choice of algorithm affects the trade-offs between runtime and accuracy in NLP. Based on the results, an optimization framework is proposed that can assist researchers and practitioners in NLP to choose the optimal algorithm for a given task and dataset, considering the desired balance between runtime and accuracy. This research provides valuable insights into the trade-offs between runtime and accuracy in NLP classification algorithms and proposes a framework that can help researchers make informed decisions about which algorithm to choose.</p> bundit Anuyahong, Thanuttchayanin Doksroifa, Urai Makkana Copyright (c) 2023 International Journal of Computer (IJC) Thu, 27 Apr 2023 00:00:00 +0000 Role of RFID Technology in Engineering Applications <p>This paper provides an extensive overview of Radio Frequency Identification technology (RFID) and its applications across different industries, rather than focusing on recent developments alone. Due to the multidisciplinary nature of RFID, proficiency in various engineering fields is necessary to fully comprehend this technology. As the use of RFID continues to expand in various industries, it is imperative to educate engineers and professionals to better understand this technology. An RFID system typically consists of tags, readers, antennae, and software, and various factors such as reading range, frequency range, and environmental considerations must be taken into account when designing such a system. Security must also be a key consideration in the development of an RFID system. To incorporate RFID technology into traditional engineering curricula, this study proposes emphasizing its connection to traditional fields such as electrical, computer, and artificial engineering.</p> Vivek Kumar, Trisha Singh, Pooja Dagar , Jyoti Dagar, Dr Rashmi Agarwal Copyright (c) 2023 Vivek Kumar, Trisha Singh, Pooja Dagar , Jyoti Dagar, Dr Rashmi Agarwal Fri, 28 Apr 2023 00:00:00 +0000 Cross-Platform Android App Gateway Payment System using Xamarin <p>Most mobile applications lacks cross platforms portability and capabilities. As such, developers tend to use specific code base that runs only on a native android application built using Java or a native iOS application built using Swift. In developing mobile application, same application is therefore required to be developed using the appropriate native app required software development. This leads to duplication of efforts, more cost, time consumption and maintenance. Although, the applications are the same, mobile application has to be developed separately because of platform independence. This paper proposes the use of Xamarin in developing mobile apps due to its cross-platform capabilities. Using Xamarin save cost, create a single code base for faster development and less maintenance while still maintaining native app performance and user experience. To substantiate Xamarin suitability, a gateway payment system was development and tested, the results showed actual cross platform functionalities in a seamless manner.</p> Osaremwinda Omorogiuwa, Ejaita Abugor Okpako, Juliana Ndunagu Copyright (c) 2023 Osaremwinda Omorogiuwa, Ejaita Abugor Okpako, Juliana Ndunagu Sat, 13 May 2023 00:00:00 +0000 Marrying Digital Performance Appraisal with Tutors’ Work Output: Evidence from Colleges of Education in Ghana <p>In this Digital Era teachers are required to develop professionalism in accordance with the development of time, science and technology, and the needs of society. Professional teachers should be able to understand the components of applicable educational concepts so as to appreciate the foundation and education policy, the development level of learners and learning approaches in accordance with the learning needs. The purpose of this study was to investigate the effects of digital performance appraisal on teachers’ performance in Colleges of Education in Ghana. The study employed descriptive research design where simple random sample was used to choose 5 principals and 139 tutors from Colleges of Education in Ahafo and Bono regions of Ghana. Data for this study was collected using close-ended questionnaire. Data analysis was done with Statistical Package for Social Sciences (SPSS version 25). The study results indicated that teachers’ appraisal processes are phenomenal in determining the performance of the teacher. The appraiser and appraisee need to be in collaboration in order to ensure the process is successfully undertaken. Communication is very essential on how the teachers’ appraisal is conducted and perceived. Training has the greatest influence on the appraisal of teachers which also affects significantly the performance of the teachers. Recommendations for further studies were made to address the study results found.</p> Benjamin Baiden, Emmanuel Appiah Dankwah Copyright (c) 2023 Benjamin Baiden, Emmanuel Appiah Dankwah Tue, 30 May 2023 00:00:00 +0000 Algorithmic Decision-Making Concerns for Software: Non-Functional Requirement Elicitation as a Solution <p>Reference [1,2] Millions of software are lunched yearly and this software depend on data to produce required output. Personal data privacy and security has been a source of public concern for some time, and is usually interpreted in terms of data obtained from interaction with software. It is difficult to know whether a software system's decisions are fair and what considerations were put in place in the system's internal decision-making process if the system's decisions are opaque. This has the potential to cause injustice and bias. In addition, a lack of openness may lead to a decrease in user acceptance and happiness. Algorithmic data-driven decision-making systems are becoming more automated, and they've had a lot of success in a lot of different applications. The General Data Protection Regulation of the European Union and other regulations limits algorithmic use of personal data and has fueled the dispute over the right to disclosure. This research adapted a crowd requirements elicitation model to develop a framework for the proper elicitation non-functional requirement. The developed model uses natural language processing integrated into a chatbot and a document extraction strategy since non-functional requirement exist also as government regulations and industrial standards. Proper and comprehensive elicitation of non-functional requirements will give accurate information on how the system performs its required task and such documents are best in terms of openness to the use of data by algorithms to avoid algorithm decision making concerns. </p> Nzechukwu Otunneme, Monday Eze, Kuyoro Shade, Ayankoya Folasade Copyright (c) 2023 Nzechukwu Otunneme, Monday Eze, Kuyoro Shade, Ayankoya Folasade Mon, 22 May 2023 00:00:00 +0000 Smart Technology Trends, Smart Supply Chain Management Implementation, and Smart Supply Chain Innovation Performance in Developing and Developed Economies <p>Many companies and scholars predict that supply chain configuration will undergo a significant adjustment during this period of change in a digitally driven future. The supply chain and management industry view these risks as including the rising frequency of disruptions to the global trading system caused by both endogenous and exogenous risks, including extreme weather events, pandemics, cybersecurity threats, and financial crises, as well as the widespread use of technology created during the Fourth Industrial Revolution. Businesses that survive the upcoming changes in customer behavior will have invested in digitization and diversity. The researcher determines the association between smart supply chain management implementation and smart supply chain innovation performance, mediated by smart technology trends in developing and developed countries, using a descriptive quantitative approach. Results show that the performance of smart supply chain innovation and smart supply chain management are not correlated. Furthermore, smart supply chain management's ability to mediate smart technological advances is notably lacking. As a result, the researcher produced an implementation strategy to improve the optimization of smart technological trends in the smart supply chain, in both developed and developing nations.</p> Tian Haichang Copyright (c) 2023 Tian Haichang Tue, 30 May 2023 00:00:00 +0000
