Machine Learning Models for Municipal Solid Waste Generation Forecasting: Models, Predictors, Performance, and Future Directions
type: item
description: This work addresses the critical research gap of unreliable waste predictions amid rapid urbanization, socioeconomic variability, and external shocks that traditional statistical methods cannot adequately handle by synthesizing studies on machine learning (ML) applications for Municipal Solid Waste (MSW) generation forecasting. Narrowly scoped to quantity (and related composition) forecasting, the review excludes broader waste management aspects such as routing, classification, or lifecycle processes. Its novelty lies in the focused, prediction-centric synthesis that benchmarks models, predictors, and performance metrics while highlighting underrepresented eXplainable Artificial Intelligence (XAI) applications and cross-regional insights. A pre-supplied corpus was filtered using strict inclusion criteria (ML-based empirical forecasting with reported performance metrics) and exclusion criteria (pre-2022 publications or non-forecasting studies), with data extracted on publication trends, geography, waste types, models, predictors, and metrics, then synthesized through narrative review and quantitative summaries. Results show a publication surge peaking in 2025, Asia-dominant research (~60%), MSW focus (~80%), tree-based ensembles (~40%, e.g., XGBoost with R² 0.88–0.95), deep learning (~30%, LSTM R² >0.90 for time-series), and socioeconomic predictors (~60%). While performance benchmarks indicate high accuracy, gaps persist in data scarcity, regional bias, low XAI adoption (~15–20%), and limited transferability. These findings underscore ML’s potential to support SDG-aligned waste optimization, with future directions emphasizing hybrid-IoT frameworks, federated learning, and expanded XAI for more equitable, transparent, and actionable global waste forecasting tools.

Improving Signal Reception In 4g Network Using Channel Equalizer
type: item
description: The efficiency of signal reception in 4G networks is critical for ensuring reliable and high-quality communication. However, challenges such as signal fading, multipath interference, and noise significantly impact network performance. This research explores the potential of channel equalizers to improve signal reception in 4G networks. Channel equalizers mitigate distortions introduced by the communication channel by adapting to changing channel conditions and restoring the transmitted signal to its original form. This study analyzes the effectiveness of equalization techniques such as linear equalizers, decision feedback equalizers, and adaptive equalizers in combating issues like inter-symbol interference (ISI) and multipath fading. Using MATLAB-based simulations and real-world signal analysis, the performance of various equalization algorithms is evaluated in terms of metrics such as bit error rate (BER), signal-to-noise ratio (SNR), and throughput. Results demonstrate that the implementation of adaptive equalizers, particularly those using least mean squares (LMS) or recursive least squares (RLS) algorithms, significantly enhances the robustness of 4G signal reception in diverse network conditions. This research concludes by recommending the integration of advanced channel equalizers into 4G network infrastructures to optimize performance and pave the way for smoother transitions to next-generation technologies like 5G.

The Potential of Machine Learning Techniques in Predicting Malaria Outbreaks in Nigeria
type: item
description: Malaria, an infectious disease transmitted by mosquitoes and caused by protists of the Plasmodium genus, poses a significant global health threat, contributing substantially to morbidity and mortality rates. World Health Organization (WHO) estimated approximately 229 million cases worldwide, with children under five years old comprising 67% (274,000) of those affected, representing the most vulnerable demographic group. Despite the prevalence of malaria, existing research has not extensively explored the utilization of machine learning techniques to predict malaria outbreaks, in Nigeria. This study aims to fill this gap by employing five supervised machine learning methods: Naive Bayes, Support Vector Machines (SVM), Linear Regression, Logistic Regression, and K-Nearest Neighbor. Utilizing meteorological and malaria incidence data spanning from 2010 to 2020, the research employed the Scikit-learn library within the Anaconda IDE, utilizing the Python programming language. Results indicate that Naive Bayes achieved the highest accuracy, with an average accuracy of 79.1% for both testing and training datasets, making it the optimal model for predicting malaria incidence outbreaks based on the dataset utilized. Following closely is Support Vector Machine (SVM) with an average accuracy of 75.45% for both testing and training data, followed by K-Nearest Neighbor with an average accuracy of 70.8%. Logistic Regression exhibited an average accuracy of 68%. However, Linear Regression, with an average accuracy of 26.05%, is not recommended for predicting malaria incidence outbreaks based on the findings of this research.

Evaluating the Efficiency of Modified Silica Gel with N, N'-Ethylenebis (acetylacetone)diamine for Copper (II) Ions Removal in Aqueous Solutions
type: item
description: This study evaluated the adsorption capacity of physically modified silica gel (SG), for copper (II) ion using aqueous solutions of N, N’-Ethylenebis(acetylacetone)diamine-C18H28N2O4 (EAD). Copper (II) adsorptive efficiency was studied under different experimental conditions and optimized before spectrophotometric analysis using EAD reagent. Results indicated that sorption of Cu(II) was favourable at pH 4, and sample volume of 50 mL, themin-1. The quantitative recovery of Cu(II) ion was achieved by elution with 5.0 mL of 1.0 molL-1 HNO3. Equilibrium data were tested and found to follow the Langmuir isotherm model. Kinetic data fitted well in pseudo-second-order kinetics. These results suggest that modified SG is an excellent metal extractor for the preconcentration of Cu(II) from the spiked aqueous phase. In conclusion, the physically modified silica gel showed a high potential for the removal of copper (II) ions from aqueous solutions. The adsorption capacity was influenced by the concentration of EAD in the solution, with the highest adsorption capacity observed at an EAD concentration of 2 mM. The study provides valuable insights for the development of effective and efficient adsorbents for heavy metal ion removal from wastewater.

description: Design and construction of a pelton wheel turbine for power generation is under taken. The pelton wheel turbine is a type of impulse turbine which under the atmospheric pressure and on this head which lies in the range of 200m. The pelton wheel turbine is an axial flow turbine. This work includes among other things the change in design parameter such as the change in discharge of water by which the velocity of jet changes due to change on the force exerted by the jet on the bucket which is responsible for the bucket movement which means the change in the speed of the runner with respect to the change in the jet velocity. The speed of the runner changes by two methods: first, is to change the discharge as well as the jet velocity which can be done by change in head and second, is the modification in the runner. Here the method used is changing the jet velocity by running at different and various height of 2.3m, 2m and 1.45m to ensure that experimental and calculations are made and graphical analysis obtained from the designed values.

Design and development of an automatic braking system in automobiles using ultrasonic sensors
type: item
description: Application of advanced breaking system using ultrasonic sensor in automobile is undertaken. An ultrasonic setup is placed in front of the vehicle and the setups consist of an emitter and a receiver. Ultrasonic emitter always emits the ultrasonic waves, whenever an obstacle is detected then the wave gets reflected and the receiver receives the signal. Reflected wave sends the signal to the Arduino Uno from that, based on distance of object, it actuates the buzzer or brakes. Ultrasonic Braking System (UBS) car provides the glimpse into the future of automotive safety. With the Ultrasonic Braking System (UBS), we can prevent more accident and save more lives.

Neural Networks Versus Conventional Computers
type: item
description: The first artificial neuron was produced in 1943 by the neurophysiologist Warren McCulloch and the logician Walter Pits. But the technology available at that time did not allow them to do much. Neural networks, with their remarkable ability to derive meaning from complicated or imprecise data, can be used to extract patterns and detect trends that are too complex to be noticed by either humans or other computer techniques. A trained neural network can be thought of as an "expert" in the category of information it has been given to analyze. Conventional computers use an algorithmic approach i.e. the computer follows a set of instructions in order to solve a problem. Unless the specific steps that the computer needs to follow are known the computer cannot solve the problem. Neural networks process information in a similar way the human brain does. The network is composed of a large number of highly interconnected processing elements (neurons) working in parallel to solve a specific problem. Neural networks learn by example. They cannot be programmed to perform a specific task. Neural networks and conventional algorithmic computers are not in competition but complement each other. There are tasks that are more suited to an algorithmic approach like arithmetic operations and tasks that are more suited to neural networks. Even more, a large number of tasks, require systems that use a combination of the two approaches (normally a conventional computer is used to supervise the neural network) in order to perform at maximum efficiency.

Digital Eye: The Role of Technology in the Life of the Blind and the Visually Impaired
type: item
description: It would have been unthinkable 30 years ago that cell phone would read, print documents and describe things to the blind. Today’s technology not only makes life easier for everyone, but it allows the visually impaired to do numerous things such as write documents, browse the internet and send and receive emails. Screen Reading software and special talking and Braille devices allow those with no vision to use computers, cell phones and other electronic devices independently. Similarly, people with low vision can use screen magnification software and devices that will allow them to see letters, pictures and other objects without having to struggle or strain their remaining vision. It is now an established fact that, with proper training and opportunity, the average blind person can do the average job in the average place of business, and do it as well as his sighted neighbor. The skills of independent mobility, communication, and the activities of daily living are known, available, and acquirable. When an individual becomes blind, he faces two major problems: First, he must learn the skills and techniques which will enable him to carry on as a normal, productive citizen; and second, he must become aware of and learn to cope with public attitudes and misconceptions about blindness. These attitudes and misconceptions go to the very roots of our culture and permeate every aspect of social behavior and thinking. The first of these problems is far easier to solve and that is the focus of this paper.

Characterization of Nutritional and Phytochemical Compositions of Locally Consumed Leafy Vegetables from Afikpo, Ebonyi State, Nigeria
type: item
description: Vegetables are an important part of human and animal diets worldwide. This is because veggies contain crucial protective nutrients for good health and illness prevention. Many vegetables, on the other hand, have yet to be described to determine their nutritional value. We used standard analytical methods to analyze the nutritional and phytochemical contents of four traditional leafy vegetables (P. soyansii, P. santalinoides, V. doniana, and C. esculenta) consumed in the South-East (Ebonyi), Nigeria. Data were analyzed using Graph Pad Prism 7.0 set at p<0.05 statistically significant level. We presented results in graphs accordingly. The maximum magnesium content was found in Vitex doniana while the lowest was found in P. santalinoides. Calcium concentration was highest in Colocasia esculenta and lowest in P. soyansii. Zinc was high in V. doniana but was not significant (p<0.05) in P. santalinoides. Vitamin C was the most abundant in C. esculenta, followed by vitamin B1. V. doniana has greater amounts of vitamins B3 and E than other veggies. A considerable number of bioactive compounds were found in the leaves of P. soyansii, P. santalinoides, V. doniana, and C. esculenta. The alkaloid content of P. soyansii was the greatest, while that of P. santalinoides was the lowest. C. esculenta has a high saponin content, while P. soyoansii has a low saponin content. In addition, tannins and phenol are both abundant in C. esculenta, but not phenol. Therefore, we reported that these vegetables have a significant dietary role in human nutrition, particularly in the prevention of malnutrition illnesses by micronutrients and bioactive supplementation.
