Coefficient of friction

In developing processing machines for plant materials, the frictional property of the seed on structural surfaces of Mild steel (MS), Plywood (PW), Concrete (CC) and Glass (GL) is a parameter which needs to be measured. In this study, the static coefficient of friction of two Nigerian beniseed accessions (Yandev-55 and E8) were determined at moisture content levels of 5.3, 10.6, 16.1 and 22.4 per cent (wet basis). These were used as inputs into designing a beniseed oil expeller. A - 2 x 4 fac...

DEVELOPMENT OF A FUZZY LOGIC TECHNIQUE FOR BIOGAS GENERATION OF ELECTRICAL ENERGY

Abstract Production of biogas energy is one of the important technical solutions that contribute to the transformation of energy system from being fossil fuel dependent to renewable energy originated. Thus, comprehensive understanding of biogas energy is necessary in order to develop an accurate and robust model that will predict and control the biogas production. This research paper develops a fuzzy logic controller model for biogas generation of electrical energy. A fuzzy logic algorithm w...

CAUSES OF CRACKS IN STRUCTURES

Building cracks are most common type of problem in any type of building. So, it is important to understand the cause and the measures to be taken for prevention. Though cracks in concrete cannot be prevented entirely but they can be controlled by using adequate material and technique of construction and considering design criteria. Due to some faulty steps during construction or some unavoidable reasons different type of cracks starts to appear on various structural and non-structural parts o...

Dynamic Behavior of Brushless DC Motor under the Application of PI, PD, PID, and Fuzzy Logic Controllers

ABSTRACT The importance of Brushless Direct Current (BLDC) motors in modern day technology cannot  be overemphasized. Its improved performance in  terms of efficiency, reliability, noise and dynamic  response, better speed versus torque  characteristics, higher speed range, and durability  over the Brushed Direct Current motors could not  be wished away. This work investigates the performance of a BLDC motor with the application of PI controller, PD  controller, PID controller, and fuz...

To soil shear strength, plastic limit, liquid limit and the liquidity index of clay soil, undrained triaxial compression test, empirical correlations, and statistical analysis of geotechnical

Soils for engineering use are often classified based on properties relative to foundation support or as they might perform under pavements and in earthworks. Geotechnical classification systems today are designed to make it easy to equate field observations to estimates of engineering properties. As moisture content of a clay-like soil increases, it goes through four distinct states of consistency: solid, semi-solid, plastic, and liquid. Each stage is defined by significant changes in strengt...

Design and costruction of bicycle ergometer

CHAPTER ONE INTRODUCTION1.1 BACKGROUND OF THE STUDY: trolling body weight, reducing the chances of heart diseases, reducing the risk of diabetes and some other chronic diseases by improving the functions of the heart, lungs and improving the biomechanical system of the body. Aside surgeryand medication, several methods have been proposed for the prevention and treatment of heart conditions. One of such methods is the use of regulated and supervised exercise as therapy both for prevention of ...

HOW TO BUILD A DRONE FROM SCRATCH

Unmanned aerial vehicles have been around for decades, but they have achieved the greatest popularity in recent years with small commercial drones. The new so-called FPV (first person view) technology gave us a unique experience of flying and the advancement of GPS systems in drones opened a whole new world for passionate individuals. Of course, drones are not the only RC flying devices on the market, but their agile multi-rotors and their capability to take amazing photos and record stunning...

ALTERNATIVE CURRENT PULSE WIDTH MODULATION CONTROL FOR INDUCTION MOTOR

ABSTRACT An induction or asynchronous motor is a type of AC motor where power is supplied to the rotor by means of electromagnetic induction, rather than by slip rings and commutators as in slip-ring AC motors. Single phase induction motor is the most familiar of all electric motors & they are similar to a 3-phase squirrel cage induction motor. It has a squirrel-cage rotor identical to a 3-phase motor and a single phase winding on the stator. There are several methods for controlling the spee...

Isolation of oil degradation bacteria

Petroleum-based products are the major source of  energy for industry and daily life. The technology commonly used for the soil remediation includes mechanical, burying, evaporation, dispersion,  and washing. However, these Technologies are expensive and can lead to incomplete decomposition of contaminants (Zaid A. Pirzada.2015) The Bioremediation technique is a pollution treatment technology that uses biological systems to catalyse the destruction or transformation...

INDUCTION MOTOR CONTROL SYSTEM

ABSTRACT The present invention relates to an improved control system for starting a three phase induction motor comprises improved power contactors configured to have a pair of three pole delta and main contactors, and a single pole star contactor for supplying AC power to star position and delta position, a timer for controlling AC power supply switching operation for star position and delta position and for adjusting a time delay of switching over from star connection to delta connectio...

Performance Analysis of Different Modulation Schemes on Space Blocks Time Code (SBTC) for Multiple Antenna Systems

     Wireless networks are becoming part of everyday life. Wireless LANs, cell phone networks, and personal area networks are just a few examples of wireless networks widely used in our everyday lives. However, wireless devices are range and data rate limited. The research community has spent a great deal of effort on finding ways to overcome these limitations. One method is to use Multiple-Input Multiple-Output (MIMO) links. The multiple antennas allow MIMO systems to perform precoding ...
