Cervical cancer is the third major killer disease in developed and developing countries. Whereas screening and other preventive measures reduce the mortality rate in developed countries, mortality rates still remain very ...

In recent times, the rate of growth in information available on the internet has resulted in large amounts of data and an increase in online users. The Recommendation System has been employed to empower users to make ...

Advanced Persistent Threats (APTs), represent sophisticated and enduring network intrusion campaigns targeting sensitive information from targeted organizations and operating over a long period. These types of threats are ...

Wireless sensor network is application specific, which is deployed in an interested area like about hundred or thousands of sensor nodes. All the sensor nodes communicate via a wireless medium and works cooperatively to ...

After many years of rigorous research and development in wireless sensor network (WSN) technology with numerous responses to innovative applications, WSNs still have some interesting unanswered questions. In this thesis ...

The study area which is the Niger Delta Province is predominantly an unconsolidated sandstone terrain, the sand grains are friable suggesting the expectation of some geomechanical problems while developing hydrocarbon ...

The use of horizontal wells with zonal isolations is a common completion practice in the oil and gas industry to check for very significant production challenges such as wellbore damage/skin, early water breakthrough and ...

In this study, we present a new analytical solution method that accurately corrects the non-isothermal effects from injection and fall-off tests. The derivative of these solutions is applied to develop the Tiab's Direct ...

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 ...

Optimizing the placement of new wells and well spacing is a vital issue in oil field development. Drilling infill wells is one way to maximize the recovery of oil from reservoirs. The problem of infill well placement is ...

This research work mainly investigates the implication of void prediction in the estimation of total pressure gradient in vertical pipes for multiphase flow systems. Experimental data was collected for a multiphase flow ...

Clastic reservoirs may be heterogeneous and exhibit lateral and vertical variations in porosity and permeability. Therefore, the spatial distribution of the petrophysical properties within the reservoirs is important to ...

Gas condensate reservoirs are single phase at the initial condition. It changes to multiphase when the reservoir conditions are located between the critical point and the cricondentherm of the reservoir in the phase envelope. ...

Discrete Event System Specification (DEVS) is a sound formal modeling and simulation (M&S) structure based on generic dynamic system concepts. PDEVS (Parallel Discrete Event System Specification) is a well-known formalism ...

Discrete Event System Specification (DEVS) formalism is a Modeling and Simulation (M&S) framework that provides a means of specifying systems. It separates a model from its simulator. The former describes the structure and ...

Timetabling presents an NP-hard combinatorial optimization problem which requires an efficient search algorithm. This research aims at designing a genetic algorithm for timetabling real-world school resources to fulfil a ...

Wireless sensor networks, thanks to recent technological advances, has become prevalent and offer a variety of applications ranging from environmental monitoring to support and automate chores fields. However, this very ...

The thesis presents the modeling and simulation of three types of lasers namely; Semicondoctor laser, Solid state laser and CO 2 laser. The rate equations were derived and simulated to examine the dynamic behaviour of the ...

This work presents numerical calculation of electromagnetic waves in unidirectional on-chip silicon optical diodes. An original optical diode, designed by Wang et. al. [Opt. Express. 19, 26948-26955 (2011)], is based on ...

The basic understanding of the underlying techniques of growing Carbon Nanotubes (CNTs) with a specific chirality is still obscure and needs to be understood so as to properly harness its potentials. Using both Classical ...
