The aim of this work is to develop a prototype of a low cost automatic internet of things extension system that looks like a regular extension system but can be operated automatically. The extension system is controlled and monitored with the use of a smartphone application. The node MCU, ESP8266, 9V 1A power adapter, breadboard power supply USB – 5V/3.3V, 5V 4-channel relay, and 1602 LCD with I2C are used in the design consideration and execution. The solution is low-cost, and it ...
Abstract: The ability to transfer power in HVAC (High Voltage Alternating Current) system has undergone limitation by reactance when compared with the fact that systems of HVDC (High Voltage Direct Current) can be accumulated to thermal limitation of the conductor. The transfer of power capabilities in HVDC and HVAC systems are compared with reference to their performance in different situations. Technological analysis conversion of existing alternating current (AC) lines into direct curre...
This paper focuses on incorporating a real time pricing in smart grids system. This scheme of real time pricing makes it possible to manage the load from the demand side or consumer side. This would provide several benefits to the domestic consumers too, apart from industrial consumers. In addition to conservation, real time pricing also comes along way in protecting and preserving the quality of equipment used by the power utility company. Real time distribution aims towards a unifo...

The engineering characterization of Ogbeke clay deposit has been investigated with a view of finding its usefulness in furnacerefractory production and home. The chemical composition analysis was carried out using Atomic Absorption Spectroscopy (AAS).The physical properties tests such as shrinkage, porosity, water absorption, modulus of rupture, refractoriness, moisture content,plasticity, cold crushing strength, thermal shock resistance and particles size analysis were carried out using inte...
The purpose of this paper is to perform path tracking for a non-holonomic mobile robot subject to kinematic disturbances using model prediction and H-2/H-infinitycontrol and by Gain-scheduled control law. In this method, the problem of tracking a mobile robot is expressed in such a someway that its kinematic error is in the form of linear parameter variable with bounded disturbance, the purpose of the design is to stabilize the controller by solving the LMI conditions for the error tracking...
As we know, nowadays issues in the agriculture field are a major concern. According to the Union Minister of Agriculture and Farmers Welfare Narendra Singh Tomar, 5,579 Indian farmers died by suicide in 2020. There are many conflicting reasons for farmer suicides which are mentioned by Activists and scholars but high debt burdens, crop failure, mental health, and personal issues have been some of the most common causes amongst them. So, what is the solution that would work in farm...
At a high frequency of vibration; the cam of a vibrator always encounters the issue of jamming or the follower rolling off or losing contact with the cam when the appropriate design is not carried out. This study, therefore, developed the shape of the cam profile of mechanical yam vibrator using cycloid motion. Displacement equations from the base circle to the cam profile were developed to obtain the shape of the cam using cycloid motion. A vibrometer was used to evaluate the developed...
Agriculture, its operations, and soils properties are inter-related. Cultivation of crops; tillage, irrigation and farm operations, commuting to and from farm plot and building of structures are greatly influenced by the soil specifically its properties. Shear stress, cohesion and angle of friction are parameters that play major roles in influencing how soils are used or worked on. It is, therefore, important to determine the shear stress, cohesion and angle of friction of the soils in Kade a...
In the world today, due to the high cost of running a tractor on a farm, there has been many research to see ways of minimizing this cost. Some of these cost come from the tire of the tractor, amount of fuel needed to run the vehicle smoothly, buying spare parts of the tractor and ensuring safety of the tractor. This thesis seeks to find the effect that tire pressures of vehicles have on the fuel consumption and the various ways of reducing this effect if there are any. An experiment was cond...

Drones are not inherently stable, necessitating the use of a flight controller. If the UAV is properly tuned, the drone will fly steadily; otherwise, it won't. Hence, we have used a PID (proportional, integral, differential) controller for a stable flight. A well-functioning PID controller should enable amazing climbs and long-range flights. But, when used singly, PID controllers can provide poor performance, resulting in a long settling time, overshoot, and oscillation. Here, we propose a ne...
Abstract Pond ash is an unwanted product from thermal power stations. Way of reducing the pollution of pond ash disposal determinations is recycled and reused in different engineering applications. The quality of pond ash can affect the quality and strength of engineering applications. This research paper using fiber reinforcement techniques to improve the geotechnical properties of pond ash. Polypropylene fiber is used to reinforce for stabilization of pond ash. In this research, some labora...
CHAPTER ONE INTRODUCTION 1.1 Background to the study The water is the most important natural resource especially in the arid or semi-arid zones that face high population growth, scarcity of freshwater, irregularity of rain- fall, excessive land use change and increasing vulnerability to risks such of drought, desertification and pollution. Thus, the availability and the sustainable use of this resource become the core of the local and national strategies and politics...
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY A mobile phone jammer or signal blocker is an instrument used to prevent cellular phones from receiving signals from base stations. The process of blocking the receiver to receive a transmitted signal is called Jamming of the signal. The jammer effectively disallows cellular phone signal when activated. These devices can be used in practically any location, but are found primarily in places where a phone call would be particu...
