An Application Of Artificial Neural Network To Maintenance Management

ABSTRACTThis study shows the usefulness of Artificial Neural Network (ANN) in maintenance planning and management.

Optimisation Of Weld-Metal Chemical Composition From Welding Flux Ingredients: A Non-Pre-Emptive Goal Programming Approach

ABSTRACT A non-pre-emptive goal programming (NGP) model for weld metal chemical composition optimization from welding-flux ingredients is proposed. 

Biogas Production From Organic Waste

ABSTRACTWaste management is a very big challenge in Nigeria today.

Solving Difference Equations by Forward Difference Operator Method

ABSTRACT In this paper a forward difference operator method was used to solve a set of difference equations. We also find the particular solution of the nonhomogeneous difference equations with constant coefficients. In this case, a new operator call the forward difference operator ∆r,s, defined as ∆r,s yn = r yn+1 - s yn, was introduced. Some of the properties of this new operator were also investigated. 

Investigation of the Grain Structure of the Fusion Zone of Single Pass Arc Welding of Structural Steel (NST 34 L-C)

ABSTRACT Some welded structures show poor mechanical properties at the weld and the adjacent zones. This has led to the collapse of structures when subjected to various torques. This research investigates the grain structure of the fusion zone of a single pass arc welding of structural steel to identify the mode of growth and grain transition of the zone and adjacent weld. Two parameters – temperature gradient in the direction of solidification and rate of advance of solidificati...

An Approach for Solving Linear Fractional Programming Problems

ABSTRACTLinear fractional programming problems are useful tools in production planning, financial and corporate planning, health care and hospital planning and as such have attracted considerable research interest. The paper presents a new approach for solving a fractional linear programming problem in which the objective function is a linear fractional function, while the constraint functions are in the form of linear inequalities. The approach adopted is based mainly upon solving the p...

Demand management based design of residential solar power supply system: a techno-economic evaluation

ABSTRACTWith high solar radiation across Nigeria, solar power system can become a viable solution to the Nigeria's electricity power crisis if the problem of high capital cost of solar power supply system can be addressed. In this study the use of demand management based design approach has been explored for reducing the capital cost of residential solar power supply system. Utilities and energy demands of thirty randomly picked homes in selected residential areas were studied The houses...

Predicting mean time between failures of a maintained equipment using artificial neural network

ABSTRACTIn this study an attempt is made to use the Artificial Neural Network (ANN) model predict the Mean Time between Failures of manufacturing equipment. The equipment failure pattern was carefully studied and some key factors affecting the Mean Time between Failures were identified. An Artificial Neural Network model, the Multi-Layer perceptron, with two hidden layers and seven processing elements was built. Twelve months of maintenance data of the machine was collected. The data ite...

DESIGN, FABRICATION AND EVALUATION OF MELON SHELLING MACHINE

ABSTRACTMelon seeds are popular in Sub-Saharan Africa and Asia. Egusi as it is called.

WHAT AND HOW ABOUT COMPETITIVE BENCHMARKING

ABSTRACTMost the domestic industries in Nigeria lag behind their foreign competitors when it comes to cost and quality.

SOLVING THE MACHINE SET UP PROBLEM: A CASE WITH A UNIVERSITY PRODUCTION WORKSHOP

ABSTRACTThis paper defined and solved the machine set up problem as a combinatorial optimization problem.

APPLICATION OF MATHEMATICAL MODEL TO OPTIMIZATION OF THE PRODUCTION CAPACITY OF PAINT MANUFACTURING COMPANY

ABSTRACTThis paper presents a case study in the development and application of a mathematical model to optimize the production capacity of a paint manufacturing company.

DEVELOPMENT OF FeO, TiO2-SiO2-CaCO3 SYSTEM AS A WELDING FLUX

ABSTRACTUsing local raw materials, various metal arc welding fluxes were formulated.

DESIGN CONSTRUCTION AND PERFORMANCE EVALUATION OF THE ABSORPTION TYPE REFRIGERATOR

ABSTRACTThe absorption refrigerating mechanism is based on Dalton law of partial pressure.

DESIGN OF A ROTARY ROASTER FOR CASSIA SIEBERIANA SEEDS

ABSTRACTTwo kilogram capacity roaster was designed and fabricated for the purpose of roasting cassia sieberiana seeds obtained from an African plant, which is capable of being used as coffee substitute.
