Abstract The current-voltage characteristic is the basic descriptor of photovoltaic device and is used to test the performance of PV panel. The manufacture specifications on solar panels are obtained under standard condition (solar irradiance of 1000 W/m2, AM 1.5 and operating temperature of 25oC) which is not the real operating condition the solar panels are exposed to on the installation site. With this, the information obtained from the manufacture specifications would not be sufficient...
ABSTRACT Power inverter is an electrical appliance that can be used with DC battery as an alternativesource of energy supply in the event of power failures and energy crisis. It is cheap, clean,very conducive and silent when in operation and a very reliable source of power supply as togenerator. Modern research and technologies have shown that inverter is one of the cheapestforms of energy generation. Throughout the world, it is readily available and can be partnerto solar energy particularly...
BSTRACT Automatic door control is becoming popular due to its numerous benefits. Automatic door control refers to the control of doors and domestic features by just sensing the present of human being at door and automatically open the door with the persons interface or by remote control. Artificial Intelligence provides us the framework to go real-time decision and automation for Internet of Things (IoT). The work deals with discussion about different intelligent home automation systems and t...
This work is on design and Construction of Automated door security system with GSM notification. Is an electrical Electronics Engineering Project.

The aims and objectives of this project are: I. Describing HVAC and HVDC power systems with their composite topologies. II. ...
This Project present the design and construction of a microcontroller based under and over voltage protection device, which is achieved using a microcontroller, transistor and other discrete components. A microcontroller PIC16F877A is at the heart of the device which performs the major control of the device. The device is simple and low cost. It can withstand loads of up to 2KVA, while allowing the supply Voltage to be connected load to vary from 200-240 volts.
ABSTRACT A power transformer is a very simple device. It is a vital link in the electronic distribution system. A power transformer is associated with faults. The design and construction of the phase fault detector is to provide simple, reliable and comprehensive electrical phase fault detections and response system. The system includes means for detecting any of the various electrical faults, such as impermissible low voltage levels, impermissible high ...

ABSTRACT Nowadays, there is an increase in the demand to connect to the internal networks of organizations by their branches from distant locations. Members of such organizations often need to access internal networks from their homes, hotels or other far away business places and external networks over the internet which is insecure by virtue of its public nature. The security of information transferred in the network becomes a major challenge when staff or partners in business access in...

The flight dynamicsof an Unmanned Aerial Vehicle(UAV)is the science ofitsorientation and control in three dimensions.The three primary orientations include: the Pitch, the Roll and the Yaw. Therear part of the tailplaneis known as the elevatorcontrol ofanUAVpitch (therotating around the transversal axis). Flight route deviations and flight altitude variations due to hash weather conditions such as shock waves or thunder storm and the wind speed/direction during flight greatly affect the pitch...
One of the advantages of automatic control system is its application to the regulation of internal combustion engines. An area of significance in fuel energy reduction and efficiency improvement is the control engine idling speed. This paper has presented a control system for improved transient response performance of a linearized engine idle speed model. In order to realize the aim of the work, nonlinear dynamics of engine idle speed are obtained and were later linearized. A proportional int...
ABSTRACT The site of electrical power plants has been a subject of interest since the advent of electricity and the distance between energy sources (mines, oil and gas fields, and water bodies for renewable energy) and distance load (cities and industrial hubs) centres. The quest for sufficient energy infrastructure to supply Nigeria’s huge and growing population of about 190 million and also to power the much-anticipated industrialization and economic growth and development made the gov...
Supreme likelihoods of fire disasters in buildings from consulted literatures includes: abnormal rise in temperature, gas leakages from gas cylinders and her accessories, and increasing concentration of smoke from burning materials. On this premise, three respective sensors were saddle with the responsibility of monitoring any anomalies from the aforementioned likelihoods of fire in market shops of which their presence above threshold possess a treat to lives and properties. These sen...
