Since the appearance of the first wind turbines at the end of the nineteenth century, wind energy has been considered to be a renewable energy source for not just developed countries but also developing countries as well. ...

The scope of Quadratic Form Theory is historically wide although it usually appears almost as an afterthought when needed to solve a variety of problems such as the classification of Hessian matrices in finite dimensional ...

The thesis presents the modelling and simulation of free running semiconductor laser. The rate equations which were derived on the basis of the fact that there must be a balance between carriers that undergo transition ...

The application of Near Field Communication (NFC) technology in every part of the world today has tremendously improved efficiency and effectiveness regarding security. The use of this technology in the healthcare system ...

The Niger Delta is Nigeria’s and Africa’s most prolific producing basin and has some untapped oil resources because of their marginality. The development of marginal oil field in Nigeria has now become an important strategic ...

Huge amount of hydrocarbon in place is left unrecovered. Integrated reservoir management, in addition to the use of new technologies improves hydrocarbon recovery. Intelligent completion is one of the technologies which ...

The wellbore integrity plays an important role in petroleum operations like drilling, well completion and production. Caliper, Electrical image logs, Acoustic televiewers (ATV) and Optical televiewers (OTV) are some of the ...

A popular model that have been used to study ferromagnetism is the Ising Model which is an arrangement of spins along a particular direction and with discrete values of + 1 . 1-D Ising model doesn't show a phase transition ...

The ratchet effect is the rectified motion of atoms using an unbiased driving force. By ‘’unbiased’’ we mean to say that the time-average is equal to zero. This can be accomplished experimentally using cold atoms in a ...

Due to the vast amount of data that is being generated by the sensors through the smart devices in smart cities, streams of data must be processed in real time to gain insight quickly and to make decisions that are in most ...

Due to the vast amount of data that is being generated by the sensors through the smart devices in smart cities, streams of data must be processed in real time to gain insight quickly and to make decisions that are in most ...

Dynamic simulators are practical tools used in the oil and gas industry to help make informed decisions, optimize production, reduce risks, and maximize hydrocarbon recovery. They are fundamental for the success and ...

Pressure build-up data in low permeability reservoirs take too long and are usually of poor quality. A pressure buildup test is perhaps the most widely performed transient test. In pressure buildup test, a well which has ...

Cuttings transportation during in non-vertical boreholes is necessary for oil and gas wells. Adequate cuttings removal from a well in drilling is critical for cost-effective drilling as high annular cuttings buildup often ...

This paper presents the use of multilayered chitosan films incorporated with antimicrobial agent, potassium sorbate to enhance effective food packaging. In this study, potassium sorbate was incorporated into multilayer ...

Metals in service often give a superficial impression of permanence, but all except gold are chemically unstable in air and air-saturated water at ambient temperatures and most are also unstable in air-free water. Corrosion ...

Unconventional resources are of major importance to the oil and gas industry due to its enormousness, however, due to the low permeability of these resources, there is a need for hydraulic fracturing. Hydraulic fracturing ...

Sentiment Analysis is the task of classifying documents based on the sentiments expressed in textual form, this can be achieved by using lexical and semantic methods. The purpose of this study is to investigate the use of ...

This work concerns one of the most important tools to solve well-posed problems in the theory of evolution equations (e.g di usion equation, wave equations, ...) and in the theory of stochastic process, namely the semigroups ...

Sentiment analysis has proven to be one of the most challenging tasks in natural language processing (NLP). Many AI systems have been developed which can detect the polarity of a sentence (degree of positivity, neutrality ...
