The idea of this project is to utilise the waste heat energy being generated in scooters. It involves tapping the heat energy being generated at the exhaust in scooters and convert to electrical energy. The amount of heat energy and the temperature is being sensed by the thermocouple and monitored. It is converted to electrical energy by the device called Thermoelectric Generator which works on Seebeck effect. The electric potential produced in thermoelectric generator is boosted by the boost converter thereby increasing the magnitude of voltage, required for charging battery. Further, the battery is used to run the vehicle during low fuel, by closing fuel valve.
KEYWORDS - thermoelectric generator, thermocouple, Seebeck effect, electric potential

This paper presents adeterministic model for SEIVR epidemic model. The purpose is to examine the existence and uniqueness of our model. Picard theorem is used toestablishthat there exists a solution and such solution is unique.

Environmental pollution is one phenomenon that is generally associated with industries in Nigeria. Estate Surveyors and Valuers whose responsibility it is to value all categories of properties in Nigeria have been charged with development of models that would take into consideration environmental pollution tendencies of industries and other facilities generation waste in Nigeria. The E-factor model was developed. The model adopts both the experimentation and survey research method. This study tries to carry out a comparative study on the effect of E-factor on ANAMMCO, a factory with international repute, and NIGERGAS, an indigenous factory. The result shows that while ANAMMCO lost N55,337,436 representing 2.09% of the original value NIGERGAS lost N16,266,020 representing 14.54% of its original value. This off course shows that ANAMMCO is better equipped than NIGERGAS in terms of environmentally friendly practices. The study therefore recommends that local industries in Nigeria should be properly supervised and that the E-factor model should be used extensively by valuers in practice in Nigeria if they will continue to play the role of environmental protection advocates.

One of the biggest threats to development in Nigeria is inadequate and erratic power supply. Any nation wishing to develop must increase its generated power in proportion to its population growth. For the so-called vision 20: 2020 to be attainable, Nigeria needs to register a take-off power generation status of 10,000 Mega Watts (that is, 10,000MW). Unfortunately, Nigeria's present power generation situation is a far cry from this, considering that it is not generating up to 4,000MW yet, with only about 40 percent of the entire population having access to public power supply. This paper takes a look at the factors militating against the realization of adequate and steady power supply in the country, the abysmal efforts being made from time to time by the relevant quarters to cub this menace and the degree of adversity faced by citizens as a result of the problem. It suggests possible ways out of the doldrums; and it is the wish of the paper that the sooner the recommendations are expeditiously implemented, the sooner Nigeria would be on the path leading to industrial development because no nations develops industrially without adequate and constant power supply.

An observer construction method for semilinear descriptor systems of the form E x  Ax f (x) , where E (singular), A are linear operators and f is a nonlinear function, is studied. Using a new approach, based on matrix theory, it is shown that an observer may be designed under certain conditions on system operators if one linear matrix inequality (LMI) is satisfied. The dynamical Model of the Operation of the HPT Axis in Autoimmune Thyroiditis is rewritten in the semilinear descriptor system form and then using proposed observer all the states are estimated. Numerical simulations are presented to demonstrate the effectiveness of the proposed approach.
KEYWORDS-semilinear descriptor system, LMI, HPT axes

Most Universities in Nigeria today are faced with decision based challenges as per precise and pre-knowledge based information on employees' recruitment / retirement and proper appraisal exercise. These have resulted to improper appraising of employees due to favoritism, or employees staying and collecting salaries more than necessary. This Developed Employees Decision Support System application (EDSS) is an interactive web-based application intended to assist decision makers in the University environment identify and solve employees' recruitment and retirement related problems, complete decision process tasks, and make proper decisions. The web based application was developed using PHP, JavaScript, HTML and MySQL. Ambrose Alli University, Ekpoma, Nigeria was used as our test bed environment. The developed system was used to automate staff records; classification, evaluation and appraisal were also executed effectively and efficiently using the system. The Developed system is recommended for Universities in Nigeria and other developing countries.

The heat transport at microscale is vital important in the field of micro-technology. In this paper heat transport in a two-dimensional thin plate based on single-phase-lagging (SPL) heat conduction model is investigated. The solution was obtained with the help of superposition techniques and solution structure theorem. The effect of internal heat source on temperature profile is studied by utilizing the solution structure theorem. The whole analysis is presented in dimensionless form. A numerical example of particular interest has been studied and discussed in details.
KEYWORDS – SPL heat conduction model, superposition technique, solution structure theorem, internal heat source

To satisfy the global need of material with reduced weight, high strength, low cost, research in the field of materials has shifted from monolithic to composite materials. The present work discusses thedevelopment of a newer metal matrix composite material using Al-5%Si alloy as base material and reinforcing it with cow dung and ricehusk ash. Both the ashes are added separately with the varying volume percentageof 2%, 4% and 6 % and fabricated using stir casting process. Microstructure and Hardness of the fabricated composite are beenStudied and compared.

This paper aimed at the evaluation of the factors that are affecting the housing maintenance and its probable solutions to the public and private housing facilities in Nigeria. Data for the study were collected through well-structured questionnaire directed to construction professionals in the construction firm and government ministries. Data collected were analysed using frequency distribution table and relative significance index. The study revealed thatDesign and proper workmanshipranked first with an RSI value of 0.9338, material specifications ranked second with RSI value of 0.847 and construction supervision ranked third with an RSI value of 0.827. These are followed by detailing of working drawings (0.813). The common solution to the housing maintenance is the monitoring and documentation of corrective actions, project expenditures, and accomplishments. This solution was ranked first with an RSI value of 0.880. Provision of accurate data for maintenance and construction programme decision making ranked second with an RSI value of 0.833. The study recommended that theBuilding professionals should participate in design and proper workmanship,building materials to be used for construction must be strictly adhere to its specifications and there must be adequate construction supervision and detailing of working drawings,
