Abstract Ferroelectric RAM or FRAM or FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory. It combines the fast read and write access of dynamic RAM(DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory). Because FRAM is not as dense (cannot store asmuch data in the same ...
ABSTRACT Cassava is considered as a potential source for the commercial production of bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological production of bioethanol using microbial amylases. With the progression and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the conversion of complex starch polymer into various valuable met...
ABSTRACT In The development of ways to reduce malpractices in examination centers in all educational institutions is an important area of research. One of the major problems discovered aiding malpractices has been the creation of mobile phones, which however is a good communication device but needs to be curtailed during examinations. In order to have a 100% assurance that no student can cheat with his or her mobile phone a mobile detector system with a frequency jamming feature was develo...
ABSTRACT This project was undertaken to determine the geotechnical properties of soils along Appleton/Zoo road. A total of nine (9) samples, both disturbed and undisturbed, were collected at chainages - 0+275, 0+325 and 0+525 respectively and each drilled to a depth of 1 m and at sampling depths of 0–0.3 m, 0.3–0.6m and 0.6–1.0 m respectively. These samples were subjected to the following laboratory tests: Particle (grain) size analysis comprising determination of percentage clay, silt...
Abstract The study examined the Knowledge and attitude of rural women towards agroforestry practices in Chikun Local Government Area ( LGA) of Kaduna State. The objectives of the study were to describe the socio-economic characteristics of rural women, describe the types of agroforestry practices, examine the sources of information on ageroforestry, find out the level of knowledge of rural women on agroforestry practices, ascertain the attitude of rural women toward agroforestry practices, id...
For a volumetric gas reservoir, gas expansion (the most significant source of energy) dominates depletion behavior, and the general gas MBE is a very simple yet powerful tool for interpretation. However, in cases where other source of energy are significant enough to cause deviation from the linear behavior of the P/Z plot, a more sophisticated tool is required. For this, a more advance...
This project covers a study of the effect of seawater corrosion on 0.34% and 0.36% carbon steel compositions. Two (2) specimens (steel rods) of length 150mm (each) for both steel compositions were obtained. Out of each was gotten four (4) specimens of 10mm length, 10mm diameter and two (2) specimens of 50mm length, 10mm diameter. This yielded a total of twelve (12) samples. For each steel composition, one (1) specimen of 10mm length and one (1) specimen of 50mm length were heat trea...
ABSTRACT One of the most important resources of a nation is energy. The significance of energy definitely cannot be overemphasized as it is immensely utilized in our everyday activities as a very germane requirement for survival and robust lifestyle. The amount of energy availability and its usage in a country measures the level of industrialization. Several devices including machines, electronics, household electrical appliances and other domestic equipment and machines, industrial pro...
ABSTRACT Whenever we think of redefined security, we think of coded electrical door lock. It is a microcontroller based security door lock that can be used in homes, offices, laboratories, etc. for more reliable and high fidelity door control system, powered by electrons panel or electromechanical panels. Due to high rate of insecurity, especially intrusion into homes and offices, this project provides the users with an electronic keypad to enter the password required to get access into home...
ABSTRACT Cell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone charging booth is to be designed and constructed in this project. The goal of this project is to create a multiple output solar cell phone chargers f...
Abstract In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of 232V was achieved.

Today, humanity can be classified as living in a “machine society” where technological tools are predominantly at different levels interfacing in the day–to-day activity of man. These livelihood activities constitute and deliver economic, social and political benefits and potential risks to the survivability of nations –especially developing nations like ours. Energy meter has been classified as Electromechanical Energy Meters. It is regarded as the most traditional and widely used en...
Abstract Energy is one of the major drivers for the economic development of any country. In order to reduce energy consumptions for sustainable development, continuous energy audit of industrial machines become necessary. Energy audit is one of the most comprehensive methods in achieving energy savings in industry and thus reducing excessive energy consumption. This paper analyzes energy auditing in power system in or...
ABSTRACT Cuckoo search algorithm (CSA) is an effective and highly reliable swarm intelligence basedoptimization approach. It is a technique of determining the most efficient, low cost and reliable operation of a power system by dispatching the available electricity generation resources to supply the load on the system. This paper presents a comprehensive review of CSA application in Economic Load Dispatch (ELD) problem. This review will assist po...
Soil materials are a vital element in all civil engineering designs hence the first step in any geotechnical engineering project is to identify and describe the soil condition if not suitable, disposal or stabilization of the soil should be carried out . In lieu of these, this research was carried out to study the effects of coconut waste ash (CWA) derived from open uncontrolled burning on lime stabilized A-7-5 soil for road construction. Natural soil was collected from a borrow pit location ...
