Abstract

This study investigates the use of communication technologies by radio stations in Benue State, Nigeria, with a focus on identifying the types of technologies commonly employed in broadcasting. Anchored in the Uses and Gratification Theory, the research adopts a survey methodology, utilizing a questionnaire administered to a sample of 151 respondents. The findings reveal that various communication technologies are used by radio stations for functions such as news sourcing, processing, and dissemination. Nearly half of the respondents indicated frequent use of new technologies in these core broadcasting activities. However, the study also shows that the broader adoption of ICT tools remains at an emerging stage, with only 32% of respondents actively using ICTs for a range of purposes, including administrative functions. A key motivation for ICT adoption was the need for timely submission of news reports, acknowledging the time-sensitive and perishable nature of media content. The study concludes that while ICT usage in radio broadcasting is growing, it is not yet fully integrated across operational levels. It recommends greater investment in modern communication technologies, increased government funding, and the recruitment of ICT-savvy professionals to enhance the efficiency and cost-effectiveness of newsgathering and broadcasting processes in Benue State.

Abstract

This study proposes a secure mobile voting system that integrates elliptic curve cryptography (ECC) with secure multiparty computation (SMPC) to guarantee vote confidentiality, integrity, and verifiability. Designed to enable scalable, privacy-preserving elections via mobile devices, the system authenticates voters using registered numbers and records ballots as encrypted points on an elliptic curve. Encrypted votes are published on a public bulletin board alongside zero-knowledge proofs to ensure their validity. To safeguard decryption, Shamir’s secret sharing distributes keys among trusted authorities, enabling collective tallying without exposing individual votes. The system incorporates ECC-based secret sharing, homomorphic encryption, and zero-knowledge proofs, leveraging the hardness of the elliptic curve discrete logarithm problem (ECDLP) for robust security. Both experimental and theoretical evaluations demonstrate that ECC significantly improves computational efficiency and scalability, making the system well-suited for resource-constrained environments. Overall, the integration of ECC and SMPC offers a practical, efficient, and secure framework for mobile elections, effectively balancing privacy, security, and performance.

Abstract

The concepts of matrix-tertions and matrix-noittrets were first introduced by Atanssov, K. T. and Shannon, A. G. [1] as mathematical enrichment exercises involving objects that lie between two-dimensional vectors and 2×2 matrices. This idea was later extended by Ajibade, A. O. [2] through the introduction of rhotrices, mathematical structures positioned between 2×2 and 3×3 matrices. Various multiplication operations for rhotrices, including heart-oriented and row–column multiplications, have been studied extensively, yielding several important results. Building on these developments, the paraletrix was introduced as a generalization of the rhotrix, defined as a structure in which the number of rows and columns need not be equal. In this paper, we extend the theory of paraletrices by introducing the concepts of differentiation and integration with respect to an independent variable occurring in a function, thereby contributing to the broader mathematical framework of generalized matrix-like objects.

Abstract

This study introduces a new probability distribution, the Uniform–Exponential Distribution, constructed by combining the Uniform and Exponential distributions to capture phenomena characterized by both constant and exponentially decaying behavior. The distribution is developed within the T-X family framework, and its fundamental properties are derived, including the probability density function (PDF), cumulative distribution function (CDF), hazard function, reverse hazard function, and moment-generating function (MGF). Analytical expressions for key moments—mean, variance, skewness, and kurtosis—are presented to describe the distribution’s shape and behavior. Parameter estimation is conducted using maximum likelihood estimation (MLE), ensuring statistical rigor in model fitting. Theoretical examples are provided to illustrate the distribution’s practical relevance. Potential applications are identified in reliability analysis, survival modeling, and environmental science, underscoring the distribution’s flexibility and utility in modeling diverse real-world processes.

Abstract

This paper addresses the need for accurate and timely single-line-to-ground (SLG) fault detection in high-voltage transmission systems, particularly to improve grid reliability in developing regions. The research objective is to propose and validate an integrated framework that combines modeling, simulation, and real-time implementation for SLG fault identification and location. Methodologically, a dual-unit detection scheme was developed: a MATLAB/Simulink dynamic model emulating a 132 kV transmission line under diverse fault scenarios, and a microcontroller-based hardware prototype employing voltage and current sensors interfaced with an Arduino Uno and GSM module to detect disturbances and transmit location data; experimental validation involved controlled fault injection, waveform inspection, and fault distance estimation via zero-sequence current and voltage dip analysis. Key findings show high-precision fault location with estimation errors consistently below 0.75% over a 30–300 km range, alongside fast response, accuracy, and cost-effectiveness. The study concludes that the combined software–hardware architecture reliably detects and locates SLG faults. The contribution and implication are a scalable, low-cost approach to reducing fault-related outages and enhancing fault management in transmission networks.

Abstract

Esa-Oke, situated within the Ilesha Schist Belt of southwestern Nigeria, was the focus of this study aimed at conducting detailed geological mapping to identify geological structures, analyze the petrography of various rock types, determine the metamorphic facies, and evaluate the industrial potential of the rocks in the area. Field mapping facilitated the delineation of lithological units, textures, structural features, mineralogy, and modes of occurrence. Rock samples of granitic gneiss and quartzite were collected and analyzed petrographically through thin section preparation and examination under a petrographic microscope. Modal analysis of the granitic gneiss revealed the following mineral composition: Quartz (22.5%), Plagioclase (25.3%), Biotite (15.9%), Hornblende (8.4%), Microcline (15.2%), Sericite (0.6%), and Epidote (0.2%). The quartzite sample consisted predominantly of Quartz (90%), with Muscovite (6%) and Fibrolite (4%). Structural features such as foliation, joints, and folds were observed in both lithologies. Strike directions ranged from 02° to 71° (average: 32°), with dip trends of 45°E to 62°E (average: 46°E) and 22°W to 62°W (average: 40°W). Joint orientations ranged between 168° and 175°, with an average of 172°. The primary mineral assemblage in the granitic gneiss includes Quartz + Biotite + Microcline + Plagioclase + Hornblende, while secondary minerals include Sericite and Epidote. Quartzite is characterized by a mineral assemblage of Quartz + Muscovite + Fibrolite. These assemblages are indicative of amphibolite facies metamorphism. The petrographic and structural characteristics confirm that the area forms part of the Migmatite-Gneiss-Quartzite Complex of Nigeria. Both granitic gneiss and quartzite in the study area are suitable for use as construction aggregates, particularly in road construction.

Abstract

The Affine Cipher, when implemented via the Tarig Transform, provides a straightforward and efficient approach to data encryption but is constrained by a limited key space and susceptibility to known-plaintext attacks. To overcome these shortcomings, this study proposes an enhanced encryption scheme that incorporates polynomial-based transformations into the Affine-based Tarig Transform framework. By introducing nonlinear polynomial mappings, the proposed method significantly expands the key space, enhances diffusion properties, and strengthens resistance to cryptanalytic techniques. Experimental evaluations confirm that the polynomial-based approach offers improved security metrics, including greater statistical randomness, while preserving computational efficiency comparable to the original implementation. These findings indicate that the enhanced scheme presents a viable and more secure alternative to conventional Affine Cipher methods for robust data communication.

Abstract

In many African cities, the accelerating forces of rapid urbanization and shifting climate patterns are intensifying the frequency and impact of climate shocks, including flash floods, heatwaves, droughts, and coastal surges. These hazards disproportionately affect informal settlements and critical infrastructure, challenges that are further compounded by fragmented data ecosystems, limited digital capacity, and inadequate real-time monitoring systems. This study presents a systematic review of 64 peer-reviewed articles published between 2015 and 2025, sourced from Scopus, Web of Science, and ScienceDirect, to evaluate the role of GeoAI (Geospatial Artificial Intelligence) in advancing urban climate resilience. The review focuses on five representative African cities—Lagos, Nairobi, Addis Ababa, Cape Town, and Dakar—selected for their diverse hazard profiles and varying institutional capacities. The study proposes a GeoAI-enabled framework that integrates Geographic Information Systems (GIS), remote sensing, and machine learning algorithms, including Random Forest, Support Vector Machines, Convolutional Neural Networks, and Long Short-Term Memory (LSTM) networks—to map spatial vulnerabilities, forecast climate hazards, and evaluate institutional readiness for proactive adaptation. Comparative analysis reveals persistent exposure hotspots in marginalized communities, with variations in predictive accuracy and hazard severity closely linked to data infrastructure maturity and governance capacity. Cape Town and Nairobi exhibit higher institutional readiness and successful integration of GeoAI into policy processes, while Lagos, Addis Ababa, and Dakar face obstacles related to data accessibility and inter-agency coordination. The study underscores the importance of embedding ethical principles, participatory mapping, and equity considerations into GeoAI systems to enhance both policy relevance and community resilience. The proposed framework offers a scalable, context-sensitive pathway for climate-smart urban governance in low- and middle-income settings, supporting the objectives of Sustainable Development Goals 11 (Sustainable Cities and Communities) and 13 (Climate Action).
