Particle swarm optimization-based type-2 fuzzy modeling for ECG signal prediction

A hybrid prediction framework based on Particle Swarm Optimization (PSO) and the Interval Type-2 Fuzzy Inference System (IT2FIS) is proposed in this paper. The major contribution is a systematic methodology for calculating the ideal parameter vector to tune the membership functio...

Isolation and Identification of Staphylococcus Species From Mastitic Dairy Cows and Associated Risk Factors in and Around Bahir Dar, Ethiopia

ABSTRACT Background Bovine mastitis remains one of the most frequent and costly diseases affecting dairy cattle, with significant impacts on health, welfare, and productivity. Staphylococcus species are among the major pathogens responsible for bovine mastitis, leading to reduced...

Performance and emission analysis of a diesel engine fueled with rice-bran and lemon-peel oil biodiesel blends

The growing demand for sustainable energy and for emission reductions has intensified the search for alternative fuels for compression-ignition engines. This study presents a novel experimental investigation of the combined use of eco-friendly biodiesel derived from rice bran oil...

Experimental investigation and predictive modeling of wear in Al7075–SiC nanocomposites

This study examines the dry sliding wear behavior of Al7075-3 wt% SiC nanocomposites using a pin-on-disc tribometer and ASTM G99 standards. Experimental results indicate that tribological responses are strongly affected by sliding distance, applied load, and sliding speed. When t...

Association between climate variability adaptation practices and household food security in three agro-ecological zones of northwestern Ethiopia

Climate variability increasingly threatens smallholder agriculture and food security in sub-Saharan Africa, yet evidence on the comparative effectiveness of adaptation strategies, particularly integrated portfolios, remains limited. This study examines the association between cli...

Gene editing applications, opportunities and challenges for crop improvement in Africa a review

Gene editing, particularly CRISPR/Cas-based new genomic techniques (NGTs), offers significant opportunities for accelerated crop improvement in developing African countries, ensuring food security, livelihoods, climate resilience, and economic growth. This review critically evalu...

Effect of hybrid layer dominance on mechanical performance, moisture diffusion, and biodegradation of kenaf/pineapple leaf fiber-reinforced PLA laminated biocomposites

Abstract Hybrid natural fiber-reinforced biocomposites can be sustainable materials for lightweight engineering, but the impact of layer dominance on the multifunctional performance of such biocomposites is still poorly known. This study focused on kenaf fiber (KF) and pineapple...

Impacts of integrated watershed management practices on soil loss and sediment yield in the Fettam watershed, Ethiopian Highlands

Integrated watershed management (IWM) has been practiced in Ethiopia to reduce soil and sediment loss since the 1980s. Hence, this study aimed to evaluate the impacts of an IWM program in mitigating soil loss and sediment yield in the Fettam River watershed. The integrated applic...

Unpacking the pathways using the stress and coping theory

Substance abuse among university students is a significant public health concern that is typically linked to underlying mental health issues such as depression, stress, and a lack of social support networks. Thus, the study’s goal was to investigate the link between social suppor...

Integrating field measurements, Green-Ampt modelling, and machine learning to map infiltration heterogeneity and water resource planning in the Ethiopian highlands

Soil infiltration governs groundwater recharge, runoff, and erosion, yet it is often oversimplified in hydrological planning. This study integrates field measurements, Green-Ampt modelling, and Support Vector Machine (SVM) classification to map infiltration heterogeneity across f...

Assessment of suitable land for surface irrigation development in an Ardy watershed, Upper Blue Nile Basin, Ethiopia

Abstract Despite its abundant water and land resources, Ethiopia has not fully harnessed its potential for irrigation development. This study assessed suitable land for surface irrigation in the Ardy watershed, Ethiopia, with the goal of utilizing the country’s abundant yet under...

Frontier mobility and the making of Nuer identity in Gambela, Ethiopia: migration, interaction, and state incorporation

The paper outlines the historical processes that encountered, delayed, lengthened and brought in the Nuer into the current Ethiopian state, particularly in Gambella region. Probing into the social and political transformations of Nuer as a result of migration, intermarriage with...

Retrieval of Optically Active and Inactive Water Quality Parameters Using Remote Sensing and Machine Learning: Evidence from Water Hyacinth-Infested Lake Tana, Ethiopia

Monitoring water quality is critical for protecting freshwater ecosystems and supporting sustainable water resource management. Lake Tana, Ethiopia’s largest freshwater lake, faces increasing agricultural and urban pressures, while conventional monitoring remains costly and spati...

Predicting utilization of emergency contraceptives in ethiopia and identifying its predictors using machine learning

Abstract Despite policy support, inappropriate use of emergency contraception in Ethiopia contributes to high rates of unintended pregnancy and maternal mortality. Traditional statistical analyses have struggled to identify complex predictors. This study used machine learning and...

Association of Moringa stenopetala based dietary consumption with thyroid function among adults in southern Ethiopia: a multicenter comparative cross-sectional study

Thyroid hormones, including triiodothyronine (T3) and thyroxine (T4), are synthesized by the thyroid gland and play essential roles in regulating metabolism, growth, and neurodevelopment. Prolonged consumption Moringa stenopetala based diet has been suggested as a potential risk...

Genotype × environment interaction and yield stability of food barley (Hordeum vulgare L.) varieties using AMMI and GGE biplot models

Abstract Background Barley is a crucial crop worldwide, but it faces significant production challenges due to limited adaptable varieties, poor management practices, and environmental factors. Food barley varieties often struggle in unfamiliar environments, leading to crop loss....

Arbuscular mycorrhizal fungi spore density and species diversity varied within plants species and between dry Afromontane forests in northwestern Ethiopia

Ethiopian Afromontane forests are rich in biodiversity and they a part of the eastern biodiversity hotspot. However, they are the most degraded ecosystems, continuously shrinking in size. Arbuscular mycorrhizal fungi (AMF) form a symbiotic association with land plants; thereby as...

Prevalence of virulence-associated genes in culture-confirmed Vibrio cholerae isolates: a PCR-based study
