Controlling Silicon and Soot Content in the Crank Case Oil to Improve Performance of Diesel Engine
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 2
In the maintenance of diesel engines, wear parts and lubricant analysis are used to predict possible worst condition of equipments, which may lead to premature failures. Content of micro element in the crank case oil can be used to find the worst condition of the equipment. Periodical lubricant analysis can reveal the microelements in the crank case oil. Copper, Iron, Chromium, Lead, Alu...

Simulating the Bird’s Leg as a Double Inverted Pendulum
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 2
The double inverted pendulum is a system which is non-linear, unstable with fast reaction. Stabilising a double inverted pendulum means the pendulum is not oscillating and moving and there is no force on it. In this paper the leg of a birdis t modelled as a double inverted pendulum and thenattempt to control it. The Linear Quadratic Regulator is used to control the system. Modelling of t...

Analysis of Tensile Strength of Bamboo Reinforced Polyester Composite
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 3
Nigerian grown species of bamboo called bambusa vulgaris which was examined to analyze its tensile strength. The fibre characteristics and tensile strength were investigated at three different fibre lengths and fibre loadings i.e 10, 30,50mm and 10, 30, 50 wt.% respectively. Fibre length was varied in each fibre loading from 10mm to 50mm, the tensile strength of the three different serie...

Production and Characterization of Algal Biodiesel from Spirulina Maxima
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 1
Biodiesel is renewable; reduce the greenhouse gas emission and potential as a substitute of fossil fuel. The aim of the current investigation is to produce biodiesel and compare physiochemical properties of spirulina maxima biodiesel (BD) with diesel fuel (DF). Soxlet apparatus was used to extract oil from algal body. Transesterification process was carried out to produce BD by adding po...

Optimization of Effectiveness for a Cylindrical Fin
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 3
A numerical study was performed to provide information about the temperature distribution of three dimensional cylindrical fin in steady state and homogeneous material properties. A brief literature review shows that much of work on fins has been carried out analytically and numerically in one dimensional and two dimensional conditions. This study is concerned about the three dimensional...

A Mechanism Concept and Design of Reconfigurable Robot for Rescue Operation
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 1
There seem to be a lot of robots that have been built up until today. Basically, the creation of robot is supposed to be a helper for a human. Robot will replace human whenever the task is really difficult or dangerous to be done by human. Recently, the robots that have been created were made reconfigurable. The purpose is to make the robot to function in more type of surroundings rather...

Development of Automatic Fish Feeder
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 2
An automatic fish feeder is a device that automatically feed the fish at a predetermined time. In a way, it is to control the fish feeding activity by using a fish feeder that combined the mechanical system and electrical system to form a device instead of manually feeding the fish by hand. Fish owners whom are away for a long time will have trouble knowing the situation of the pond or a...

Energy Analysis of Simultaneous Charging and Discharging Concrete Bed Storage System
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 16 Issue: 1
One of the major challenges with the use of solar thermal energy is the intermittent nature. As such, present day research is geared towards energy storage systems in which thermal energy is stored during the day for later use. However, in many engineering applications there is a continuous steady demand for energy. Experiments were conducted using concrete mix of 1: 1.2: 1.1 of cement, ...
