Developing countries have been plagued by recurrent cases of infectious disease outbreaks;coupled with the limitation of traditional disease control strategies, other approaches have been explored for disease control, with ...

Cyber threats are currently on the rise, which has caused individuals, industrial control systems (ICSs), critical infrastructures (CIs), and nations to be subjected to attacks with great losses. Among the cyber threats ...

In the world today, the size of complex problems and systems has increased, due to the advances in technology and the area of computer design and architecture. Modeling and predicting the behaviour of complex systems ...

This research describes the application of a production economic approach which attempts to quantity stimulation treatments performed on different wells undergoing a decline phase in their production and to obtain based ...

Well stimulation consists of several methods used for enhancing the natural producing ability of the reservoir when production rate declines. A de tailed literature review of some of the well published stimulation models ...

Waterflooding is the most dominant secondary oil recovery method and its popularity is mainly due to the general availability of water, the relative ease of injecting water, the ability of water to spread easily through ...

Reservoir development planning and well placement significantly affect hydrocarbon recovery. Therefore, strategic well placement and development techniques are essential to minimize the risk of unproductive drilling and ...

In this thesis, we consider the problem of approximating solution of generalized equilibrium problems and common fixed point of finite family of strict pseudocontractions. The result obtained is applied in approximation ...

In this thesis, an iterative algorithm for approximating the solutions of avariational inequality problem for a strongly accretive, L-Lipschitz map and solutions of a multiple sets split feasibility problem is studied in ...

Monotone operators and accretive operators are essential to modern optimization and xed point theory. Monotone operators were rst discovered by Minty in real Hilbert spaces to aid in the abstract study of electrical ...

Let H1 and H2 be two Hilbert spaces and Aj : H1 → H2 be bounded linear operators and Ui: H1 → 2H1, Tj : H2 → 2H2, 1 ≤ i ≤ n, 1 ≤ j ≤ r be two multi-valued demi-contractive operators with demi-contractive constants βi and ...

In this thesis, the problem of solving the equation of the form Au = 0, (0.0.1) where A is a nonlinear map (either mapping a Banach space, E to itself or mapping E to its dual, E ∗ ), is considered. This problem is desirable ...

From the inception of the oil and gas industry, water production has always been an aching problem for various operators. Throughout the productive life of a field, oil production is often accompanied with some amount of ...

Nigeria economy solidly depends on fossil fuels, which serve as the major source of energy and revenue. Fossil fuels, especially petroleum, are readily available to meet the increasing energy demand of a growing population. ...

Drilling fluids play sophisticated roles in the drilling process which include, keeping formation fluids at bay, stabilizing the wellbore without damaging the formation, lubricating the bit and drill-string and clearing ...

The texture and size distribution of various species of gangue minerals affect the beneficiation of barite and lower the specific gravity of barite as-mined. About 9% of the barite used in the oil industry in Nigeria is ...

Over-exploitation of groundwater over the years has imposed immense pressure on the global groundwater resources. As demand of potable water increases across the globe for human consumption, agriculture and industrial uses, ...

The presence of heavy metals in water and soil by metalliferous mining activities at MNG-Gold Mine was fully investigated. The extraction of gold in recent years, has led to the generation of huge quantities of solid and ...

The presence of heavy metals in water and soil by metalliferous mining activities at MNG-Gold Mine was fully investigated. The extraction of gold in recent years, has led to the generation of huge quantities of solid and ...

Due to rapid industrialization, the demand for heavy metals is ever increasing, but the reserves of high-grade ores are diminishing. Therefore there is a need to explore alternative sources of heavy metals. Ore mine gangues ...
