Users’ perspectives approach provides an unbiased assessment of Quality of Service (QoS) of voice offerings in telecommunication networks. This approach is implemented using subjective or objective technique. Though the ...
Asphaltene Precipitation (AP), a major challenge in the petroleum industry, causes flow assurance issues in reservoirs, pipelines and flow lines. It is therefore important to properly characterise petroleum fluids and ...
Langmuir adsorption isotherm has been used extensively when incorporating gas desorption into gas Material Balance Equation (MBE) framework. However, it over-estimates adsorbed gas reserves at higher pressures without ...
The Spark Ignition (SI) engine remains a global prime mover in the agricultural and
transportation sectors as well as in electricity generation. However, its low thermal efficiency
and consequential high emissions as ...
Compression Ignition (CI) engines are widely used in transportation and power generation
industries in Nigeria. However, their low thermal efficiency and high emissions have
necessitated continuous efforts at redesigning ...
Hot-rolled St60Mn steel is commonly used in the construction of bridges and houses. Reduced quality characterising hot-rolled steel has become a major research concern. Previous studies focused on the effects of chemical ...
Aluminium alloy wheels are increasingly popular for their light weight and good thermal conductivity. However, there are efforts to introduce Cooling Holes (CH) to reduce their weight without compromising structural ...
Noodle, a convenient wheat-based food, is high in carbohydrate but low in protein and
vitamin contents. Imported wheat is mostly used to meet the demand for convenience
foods preparation in Nigeria. Alternative to ...
The need to remove more water in agricultural production, without limiting crop growth and yield, has
led to the development of crop models. This makes more water available for domestic and industrial

The use of insecticides against malaria vectors has been a good approach to control malaria, but its efficacy is threatened by mosquito resistance to the lethal doses. In Nigeria, Anopheles funestus is gradually becoming ...
Silver (Ag) and copper(II) oxide (CuO) nanoparticles are used in personal care products because of their antimicrobial properties. Their continual release into the environment may enhance genotoxic effects in the ecosystem, ...
Erelu reservoir is the main source of water supply for domestic, agriculture and fishing activities in Oyo town. The reservoir receives inflow of materials from the catchment where various anthropogenic activities occur ...
The Lee-Carter (LC) model was primarily designed for modelling the mortality pattern with Gaussian error structure in most developed countries. Attempts at using LC for describing the pattern of mortality in developing ...
Distributed Lag Model (DLM) is a major workhorse in dynamic single-equation regression, which
requires stringent assumptions for its validity. One of the critical assumptions of DLM is the
normality of the Error Term ...
