ABSTRACT The challenges faced by students in Nigerian Universities are increasing. The need to curb some of these challenges has motivated the researcher to design an online project and assignment submission management system. Students face the challenge of meeting the deadline for assignment submission and also the cost of printing hard copies of paper necessitated this research work. The system allows students to submit assignments or projects online to various lecturers and supervisors wh...
ABSTRACT Over time, payment systems have been changing, this started with Trade by barter and now the era of electronic wallet. “Wallet” in the conventional sense of the term, refers to a purse or folding case for safely holding money. An electronic wallet refers to a digital way of holding money. This system also provides users with the features of making different kinds of payments on campus and also has a campus E-commerce platform attached to it. This is aimed at promoting cashless p...
ABSTRACT The subgradient extragradient method is considered an improvement of the extragradient method for variational inequality problem for the class of monotone and Lipschitz continuous mappings in the setting of Hilbert spaces. In this Thesis, we proposed an improved subgradient extragradient method for variational inequality problem for the class of monotone and Lipschitz continuous mappings in the setting of real Banach spaces.
ABSTRACT 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 has taken the area to greater heights of confidence and reliability, especially for medical personnel, as well as the patients. This project focuses on helping dependent people live their lives more productively by helping them manage their lives better. With this a...
ABSTRACT Technology has been in support of online (Electronic) examination for a while now, and has progressively improved the online examination process over the years. However, some schools and institutions are still involved in the manual system of writing exam. This manual system, has a lot of downside such as the tediousness and time mismanagement etc. Some other institutions/Examination bodies are also involved in the use of multiple questions on an online web platform. But this develo...
ABSTRACT Weighted and average dose within a scan volume of a phantom have been evaluated and validated using two different devices and techniques. The Barracuda electrometer and Ion Chamber techniques were applied on a 16 slice Siemens CT scanner and the results compared to the console displayed CTDIw and CTDIvol valuesfor accuracy and compared to each other for validation purposes. With fixed exposure parameter of 130kVp and varying tube current-time products from 140mAs to 300mAs for the ...
ABSTRACT 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 the behavior of a system, while the later generates the trajectories of these descriptions. P-DEVS (Parallel DEVS) is the version of DEVS that allows one to express at the modelling level, the parallelism present in a system. Though the algorithm is well defined, ...
ABSTRACT Adebayo Gbenga Waliyi: Study and implementation of Wireless Sensor Network to Manage Energy in a Smart Home. (Under the direction of Ousmane Thiare) Many studies have shown that smart homes can use energy more efficiently than traditional buildings. Thus, several researchers have advocated building a smart home in order to reduce energy consumption. In the literature, Wireless Sensor Network is adopted as the dominant technology for every proposed smart home . In this thesis I expl...
ABSTRACT This dissertation presents the combined results of analytical, computational and experimental study of the effects of surface texture and nanoscale surface oxides on the optical and mechanical properties of silicon single crystals and MEMS thin films. The first part of this work is focused on the analytical modeling of the reflectance of flat and textured silicon substrates. The model was used to study the reflection behavior of textured silicon surfaces under non-normal incidence. ...
Wireless Sensor Network (WSN), is composed of several spatially distributed nodes, and connected to one or more sensors, which monitor a large physical environment. The nodes (wireless devices) are typically small in size and capable of performing sensing, on-board processing, communication and storage. WSNs [1] offer economically viable solutions for a variety of applications such as current implementations to monitor factory instrumentation, pollution levels, freeway traffic, and the struct...
ABSTRACT This study investigated the impact of ICT three initiatives as perceived by Wiawso College of Education tutors at an independent school in Sefwi Wiawso. A qualitative data was gathered for this Case Study by administering questionnaire to 43 tutors of the college and two administrative staff. Data were analysed using descriptive statistics. First and foremost, evidence was found of an overall increase in the use of ICT since the three initiatives were implemented. Secondly, the provi...
ABSTRACT A Krasnoselskii-type algorithm for approximating a common element of the set of solutions of a variational inequality problem for a monotone, k-Lipschitz map and solutions of a convex feasibility problem involving a countable family of relatively nonexpansive maps is studied in a uniformly smooth and 2-uniformly convex real Banach space. A strong convergence theorem is proved. Some applications of the theorem are presented.
ABSTRACT Deep Neural Networks are now deployed for many modern artificial Intelligence applications including computer vision, speech recognition, self-driving cars, cancer detection, gaming and robotics. Inspired by the mammalian visual cortex, Convolutional Neural Networks (CNNs) have been shown to achieve impressive results on a number of computer vision challenges, but often with large amounts of processing power and no timing restrictions. Software simulations of CNNs are an efficient ...
The contribution of this project falls within the general area of nonlinear functional analysis and applications. We focus on an important topic within this area: Inequalities in Banach spaces and applications. As is well known, among all infinite dimensional Banach spaces, Hilbert spaces generally have simple geometric structures. This makes problems posed in them easier to handle, this is as a result of the existence of inner product, the proximity map, and the two characteristic identitie...
ABSTRACT Acoustic effects such as absorption/amplification of acoustic phonons, Acoustoelectric Effect (AE) and Acoustomagnetoelectric Effect (AME) were studied in Carbon Allotropes. In this thesis, the Carbon Allotropes considered are Graphene Nanoribbon (GNR), 2-dimensional Graphene sheet, and Carbon Nanotubes (CNT). The Boltzmann transport equation (BTE) and the phonon kinetic equation (PKE) were used. All results were analysed numerically and graphically presented. Using BTE for Armchair ...
