The performance characterization of a medium scale vegetable oil plant in Owerri is presented. Using the queue methodology, it was established that the plant operates the queue model [(M1/M2/s);(infinite, F-C,F-S)] with Poisson arrival mass rate of palm kern…

This paper presented a simulation model of an enhanced e-voting system based on bio-cryptographic schemes. A lot of work has been done on e-voting systems using biometrics as well as cryptographic schemes but not fusing both. This work provides an improvemen…

Chemical treatments are considered in modifying the fiber surface properties. In this paper, two different chemical modifications on natural areca fibers for use in natural fiber-reinforced composites are studied. These chemical treatments include alkali and…

The inhibitive effect of Moringa leaf (LE) and Moringa seed (SE) on mild steel corrosion in 1M H2SO4 solution was investigated using standard weight loss at 32oC and 60oC.The analysis of the experimental results revealed that the leaves and seeds extract est…

The focus of this study is to understand the prevalence of corrosion-related failures in Nigeria Oil/Gas Industry and seek ways to arrest the degradation of the facilities. The hash environmental conditions are known to severely affect the equipment integrit…

Synthetic fibers (such as glass, carbon, ceramic fibers, etc) which were imported at huge cost could be replaced by natural fibers such as flax, hemp, jute, kenaf, etc. and widely used. In this research work, banana fiber reinforced vinylester matrix composi…

Electricity demand in households resulting from unpredictable consumption pattern has been serious concerns in Nigerian power industry. Existing metering systems have not addressed the various challenges of enabling daily tracking of power usage patterns in …

This paper examines the feasible development of magneto-hydrodynamic (MHD) power plant in Nigeria. It proffers the possibility of harnessing magneto-hydrodynamic technology as dependable energy mix for ameliorating epileptic and incessant electric power fail…

This paper studied and highlights the security and technical challenges facing the deployment and utilization of IEEE 802.15.4 based Wireless Sensor Network (WSN) devices used to facilitate remote oil and gas field monitoring in the Niger Delta region of Nig…

Machine control, especially that of induction motors, is an essential consideration on the program of any industrial world. Efficient machine control, not only saves power consumption, but increases productivity. Threephase induction motors produce mechanical…

This work presents the uniform linear Array model of a simple adaptive antenna array based on signal to interference plus noise ratio (SINR) maximization. A simple adaptive antenna array which can form part of a WCDMA base station structure was developed. In…

The engineering profession has been invaluable in the improvement of capacity building and sustainable development. This research work examines the impact of authenticity of engineering profession on socioeconomic and human development. The focus of this stu…

Despite the government huge investments into the power sector, to adequately ensure regular power supply to electricity consumers, there are still gross inadequacies on the regularity of electricity in the country. This paper analyses the use and impact of D…

In the concept of handoff performance in mobile communication, Bit Error Rate (BER) was not fully considered, hence this dissertation focused on Mobility Management Scheme (MMS) in mobile communication using BER as sensitive parameter as well as throughput, …

With rapid growth in the use of automated teller machines (ATMs), there is need to develop secure, robust and reliable schemes to securely/correctly authenticate users. The conventional ATM authentication schemes available are mostly cryptographic based and …

This paper studied the influence of water/cement ratio on the flexural strength of concrete made with unwashed local gravel from Abagana in Anambra state. In the research work, concrete beams of dimensions 600mm x 150mm x150mm —three for each experimental po…

This paper presents an interactive M-file algorithm capable of running in a MATLAB environment, which can estimate the number of theoretical plates a distillation column ought to contain at total reflux to efficiently separate a multicomponent mixture into t…

Induction motor is the most widely used electromechanical machine due to its low cost and minimum maintenance. It has more losses, less efficiency and high power consumption when working at variable speed. The influence of these motors (in term of energy con…

This paper focuses on the analysis of Owerri network using load frequency control. The LFC is further analyzed using fuzzy logic controller and neural network controller for optimization. The result is compared and relevant conclusions are drawn. Applying a …

This study is on the susceptibility of AISI 304L austenitic stainless steel welded joints to localized pitting corrosion in sea water. AISI 304L is more resistant to corrosion primarily because of its low carbon content. This makes it less susceptible to wel…
