This paper presents the findings of a research work conducted on how to improve the mechanical properties of concrete using Date Palm Seed Ash (DPSA) as partial replacement of cement. The DPSA used was obtained by controlled burning of date palm seed in a kiln at a maximum temperature of 630oC for eight hours and air cooled afterwards. The ash obtained was sieved through 75μm sieve and its oxide composition analysed using X-ray fluorescence (XRF) procedures. DoE method of mix design was used...
The effect of particle size of date palm seed ash (DPSA) on concrete properties was investigated through the use of different fineness of date palm seed ash (600um, 300um, 150um and 75um) at 2.5% replacement of cement with date palm seed ash and tested for compressive strength at 7, 21, 28 and 56 days curing duration. The consistency and setting times of cement-DPSA paste was also researched to determine the amount of water required to prepare hydraulic cement paste for testing. The date palm...
The suitability of palm kernel shell as a partial replacement of fine aggregate in concrete was researched to verify if concrete made with palm kernel shells meet some minimum standard prescribed for strength and density. Based on British standard classification of fine aggregate as aggregates passing the number 4 sieve of 4.75mm size or slightly higher sizes depending on local requirement, crushed palm kernel shells of particle diameter not greater than 5.0mm was used to replace river sand a...
ABSTRACT Composites have been developed with great success by the use of reinforcement. Monolithic materials cannot possess all the properties to be obtained hence, the need to employ the use of composite materials. Aluminum is generally utilized as a basic material particularly in the aerospace industry in view of its light weight property Be that as it may; the low quality and low melting point were continuously an issue.However due to these limitations, intense exploration on the use of me...
In this paper, the simplicity of the convectional Histogram in-motion mapping for obstacle avoidance technique which is now modified and modeled to Hybrid histogram in-motion mapping (HHIM) for autonomous mobile robot navigation and obstacle avoidance was primarily developed by AKWARA UCHENNA C. to solve robot navigation problems for completely unknown environment particularly for a static wave concave shaped obstacle. The developed model is to address the problem associated with a static wav...
In this paper, the research study on velocity heat conductivity (VHC) model for two autonomous mobile robots in energy workspace is adopted. The model is applied to solve and address; the conversion of heat energy conductivity into kinetic (internal) energy conductivity of the robots, to obtain the velocity energy placement and to derive a velocity heat conductivity mathematical model for algorithm simulation drive using specific heat capacity and thermal diffusivity response in energy worksp...
In this paper, the research on virtual force vibration concept for four resonance autonomous mobile robots navigation is welcome. This concept is adopted and applied to solve and address; the behaviour of four autonomous mobile robots without initial force of vibration, the amplitude frequency of the vibrating medium, the effect of inapplicable resonance, the wavelength of vibration and the vibrating amplitude length of the four mobile robots. Robot 1 is set into motion at an amplitude freque...
ABSTRACT:- The use of fingerprint for identification has been employed in law enforcement for about a century. A fingerprint locker system using microcontroller uses fingerprint recognition system as a process of verifying the fingerprint image to open the electronic lock. This research highlights the development of fingerprint verification system using Arduino 1.6.3. Verification is completed by comparing the data of authorized fingerprint image with incoming fingerprint image. The incomin...
In this paper, the virtual thermodynamic temperature concept (VTTC) proposed for 2D obstacle environment for autonomous mobile robot is welcome. The concept emphasis on the heat transfer and temperature measurement of an obstacle and robot workspace with reference to the virtual target concept (VTC) for Lengthy, Concave and Wave concave shaped obstacle. This method is used to address the heat transfer (internal) and the temperature incremental area that occur in 2D workspace for autonomous ...
ABSTRACT Security concern have existed since time immemorial. But the challenges has never been as readily manifested as they are presently. This is rather disconcerting. Moreso, because some of the security challenges and problems we encounter daily in the contemporary society are almost entirely unpredictable. Indeed, rapid growth and use of mechanical arts, applied science, and revolutionary dynamics of society apparently blend well with the desperate nature of the criminally minded to ...
The aim of the project is to develop a numerical tool used to predict vessel motions of a turret moored FPSO, then perform a comparative analysis between the 6 degree of motions measured on the FPSOs during the 7 months period and the predictions from this numerical model. The first step was to carry out statistical and extreme value analysis of the metocean data obtained from hindcast and measured data, this gave an insight to the characteristics of the measured data and how it closely relat...
The fast growing and developing population of the world is so busy that instant food noodles are gaining ground for both humans and domestic animals. Incidentally, the machines involved in the production of these food noddle extruders are imported which results in the depletion of our foreign exchange reserve. Consequently, there is a growing need to design and produce these machines locally. This project has achieved the design, fabrication and testing of noddle extruder. The fabrication is ...
ABSTRACT-Power system planning is a vast and important issue for operation and expansion of power delivery. One of the basic objectives of planning is to determine the right schedule for investment in new devices which ensures secure and economic power delivery for predicted customer demand. System planning also addresses the question of reliable and stable operation; hence reliability and stability analysis are also included in adequate power system planning studies. This work explores the a...
