Abstract: Finding faults and partial shadow conditions are the key challenges for photovoltaic (PV) system. Furthermore, by being aware of how many broken modules and strings there are, the power loss can be averted. Some studies are conducted in this project to address these issues in order to distinguish between faults and partially shaded conditions as well as the quantity of mismatched modules and strings for a dynamic change in irradiation. Based on a straightforward observation ...
ABSTRACT The use of solar energy through photovoltaic systems has seen rapid growth in recent years due to its environmental benefits and cost-effectiveness. However, one of the main challenges that PV systems face is the accumulation of dust and debris on solar panels, which can significantly reduce their efficiency. To address this problem, we propose the design and development of a solar cell cleaning robot. This project aims to create an autonomous robot capable of cleaning solar panels e...
This research work delves into a comparative analysis of Perovskite solar cells crafted using different antisolvents, namely DMF, DMSO/DMF, and TOL/DMF. The investigation focused on assessing their structural and optical properties, as well as their solar cell efficiency and stability. Notably, the perovskite layer formed with DMF displayed numerous pinholes, while the use of TOL/DMF as a mixed solvent yielded a pinhole-free layer. Spectral analysis revealed heightened light absorption in the...
This project work “Reliability analysis of a continuous beam using Hasofer-Lind Reliability Method” was primarily concerned with the effect of varying parameters such as load, modulus of elasticity, moment of inertia and span length on the reliability of a continuous beam. The limit state considered is deflection, and the allowable deflection is specified as L/360. The maximum deflection is 0.0069wL^4/EI and it occurs at 0.446L from either end (AISC, 1986). Reliability analysis, expre...
ABSTRACT This project tittle ‘’basic principle of machining’’ deal with the operations on lathe, milling and some part of arc welding, turning, taper turning, threading, knurling and chamfering, while on milling machine spur Gears were cut, forming a hexagon shape and square shape were all done on milling machine. A simple component/part which contained all the above mention operation were produced in one work piece. In conclusion we are able to produce spurs gears, square thread, an...
ABSTRACT An intercom is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones. Four-way intercommunication system is nothing but the communication within four persons not close to one another. This does not mean w...
This project involved the conversion of a conventional bicycle into an electric hybrid bicycle using a hub motor, battery, controller, throttle, and battery indicator. The selection of a flywheel-based regenerative mechanism was justified based on its superior energy storage capabilities. The challenges faced during the assembly, including bearing and clutch drive iterations, were overcome through the use of multiple bearings, metal casting, and welding. The implementation of an indirect...
ABSTRACT An innovative approach to achieving autonomous vehicle navigation through the integration of image processing techniques and the Raspberry Pi platform. The aim is to develop a self-driving system that can analyze real-time images captured by onboard cameras and make informed decisions based on the detected objects and road conditions. By employing advanced computer vision algorithms, such as object detection and lane detection, the system can identify and tracking obstacles, recogniz...
This project is about the Design and Construction of a Vehicle Tracking and Accident Alert System (VTAA) using GPS and GSM Technology. It comprises of integration between GPS receiver, microcontroller and GSM module, and of course the push button for accident alert activation. The combination of all this technology will produce our VTAA system. The GPS module receive the coordinate of the point at which the system is located, controlled by the user using command interfaces through...
ABSTRACT Web-based health management system for National Health Insurance Scheme is considered in this project work as an online information storage and retrieval internet portal where the stakeholders registered and participating in the National Health Insurance Scheme of the federal ministry of Health will be able to access relevant information regarding NHIS. The Internet portal will also be useful to prospective or intending participants who want to key into the programme. The stakeholder...
ABSTRACT Condition monitoring of Electrical power equipment has attracted considerable attention for years. The aim of this work is to use Fuzzy logic (FL) Tool Box in building a simulation system that will diagnose all kinds of incipient faults, phase to phase fault and overloading in a transformer and monitor its conditions. Current and rate of change of current with time have been identified as the input variables, duly represented in the programme as “Error” and “Error-Dot”. Thes...
The piston is a heart of the engine and its working condition is the most exceedingly bad one of the key parts of the engine in the workplace. A piston is a segment of responding piston, responding pumps, gas compressors and pneumatic chambers, among other comparative systems. It is the moving part that is contained by a barrel and is made gas-tight by piston rings. In a piston, its motivation is to exchange force from growing gas in the barrel to the crankshaft through a piston bar and addit...
A CMOS biosensor with a folded floating-gate is created to detect charged biochemical molecules. It contains a FET, a control-gate and a sensing area. The floating-gate spans the whole device, allowing the sensing area to be placed on top of the FET, resulting in a decrease of the device's total area. The device is sensitive to the polarity and quantity of charged poly amino acids and could be used for electronic recognition of temporal and spatial migration of charges, such as in biological ...
ABSTRACT The Conventional Levenspiel and Smith fixed point continuous monitoring method is used in the evaluation of the dispersion number and the dispersion coefficient, I? of river Ebm under study. Comparisons were made with Agunwamba’s method and both methods for different results. The leverspiel and Smith method gave higher values than those obtained with the Agunwamba's method except in me station. This is due to experimental errors. The Agunwamba's method though more tedious gave mor...
