ABSTRACT Numerous failures and eventual losses in the chemical industry have been traced to corrosion processes. Failures resulting from the inability of metals to support designed load requirements because of losses imposed by corrosion effects can be combated economically through the use of chemical inhibitors. Despite the fact that synthetic inhibitors are effective, nonetheless they are associated with problems of toxicity, disposal, litigation and enormous costs. In order to protect the...
ABSTRACT Converting the huge amount of waste cooking oils presently generated globally to biodiesel as complementary energy source to fossil fuel is one of the major routes to sustainable energy management. However, producing quality biodiesel at established optimum conditions, through a clean technology with favourable environmental implications is of greater importance. This research focused on achieving the latter through alkali catalysed trans-esterification process of biodiesel producti...
ABSTRACT Due to the increase in the number of vehicles caused by rapid population growth in urban areas, the demand on parking infrastructure for the general has increased significantly (Polycarpou & protopapadakis, 2013). As (Polycarpou & protopapadakis, 2013)further points out, finding a free-parking space in urban areas like hospitals, hotels, shopping malls, event centers especially during peak hours is more or less impossible, in many cases. Drivers have to drive round looking for free ...
ABSTRACT The use of fossil fuel in electricity generation has created three significant issues for the world to deal with. The issues are security (availability and reliability) of supply, climate change and the cost of fuel required for electricity generation. Covenant University, currently running a cluster of stand-alone diesel powered generating plants situated at different locations within the campus has a lot of unused available capacity within the system which invariably increases the...
ABSTRACT Market-based pricing for Liquefied Natural Gas (LNG) may be less remunerative or uncertain for exporters in the evolving market. The possibility of rent-maximizing could encourage them to collude through an influence mechanism. This book examined the feasibility of Uniform Pricing (UP) or Volume Control (VC) in the Atlantic Basin and analyzed the consequences of such a development on LNG trade. So far, no existing model specifically considers the sustainability and effects of an LNG...
Microcontroller Based Pump And Level Indicator
ABSTRACT A power system is set up basically to meet the demands of the customers. However, interruptions which are largely unavoidable contribute to the unavailability of power and thus prevent power system from achieving this. In most cases, it is the sustained interruptions that greatly affect both the utility company and its customers. Hence, it is necessary to find means of determining which component failure contributes most to the unavailability of the distribution system, and how this...
ABSTRACT There have been several cases of unwanted entries into the laboratories and offices within the school environment, and in a quest to reduce these occurrences, this project "a micro-controller based door access control system using Radio Frequency Identification" was proposed to control access to restricted areas within the school. Access control is a process by which users are granted access and certain privileges to systems, resources or information. Radio frequency identification ...
Abstract Mitigation against increasing carbon dioxide, CO2, in the atmosphere is uppermost in environmental research due to its negative effects and the most effective approach is in the area of underground carbon storage. In this research, a model was developed to study the possible alteration of porosity and permeability during CO2 injection to Kwale sandstone reservoir, Kwale shales, Imeri oil sand and Ota Kaolinitic clay. The proposed model combined the Timur model irreducible water satu...
ABSTRACT Rate decline analysis is an essential tool in predicting reservoir performance and formation property estimation. The use of historical production data to predict future performance is the focus of the empirical domain of decline analysis while the theoretical domain focuses on the use of such data to estimate formation properties. A number of attempts have been made to establish the theories of rate decline in solutiongas drive reservoirs. Such attempts have established the theoret...
ABSTRACT The objective of this study is to produce and determine the mechanical properties as well as water absorption characteristics of unsaturated polyester-groundnut shell particle composite. The aim of the study with varying weight of groundnut shell particle is to find the composite with optimum mechanical properties. Groundnut shell of undersize particle of 300 microns was introduced at different percentages into the unsaturated polyester resin. Composites were produced at 2%, 4%,...
ABSTRACT This project presents a Microcontroller-based temperature and humidity measuring and control system which can be implemented in a poultry farm. The control of temperature and humidity have, overtime, become a major part of control systems operated in environments where these quantities are crucial entities. In this project, DHTI I temperature-humidity sensor is used for the sensing of the temperature and humidity of the poultry house, and it is then controlled using a microcontrolle...
Introduction This paper considers the influence the electrical engineer wills in any community and aims at the following: (1) Sensitization of electrical engineers towards self sustenance (11) The electrical engineer as a job creator. (iii) the electrical engineer as an employer. (iv) The role of electrical engineers in the creation of cottage industries and long term investments. The paper hinges its arguments on the commercialization of ideas as a basis for sustenance through lone term inv...
ABSTRACT The performance of a pavement depends on the quality of its base, sub-base layers and sub grade. As the foundation for the pavement's upper layers, the subgrade layer plays a key role in mitigating the detrimental effects of static and dynamic stresses generated by traffic. Therefore, building a stable base course is vital for constructing an effective and long lasting pavement system. This study proceeds from the basis that, construction of foundations of most engineering structure...
Abstract The conventional method of design of reinforced concrete structures commonly used in Nigeria is the BS 8110 method. This project shO\S a comparative stud~ of BS 8110 and Eurocode 2 for the design or reinforced concrete elements of a building Vith the aim of determining "hich of the two codes provides the most economic design is carried out using manual calculations. A library complex of three storey building was selected and designed taking into account dead and live loads and assumi...
