Test and measuring instruments are an indispensable in any electronics research, development or design environment. Test and measuring instruments can be categorized as digital and analog. Analog systems change their signal output linearly with the input and can be represented on a scale by means of a pointer. In the other hand, digital... Continue Reading
ABSTRACT Microcontroller based remote control system is a project design of a system that uses infra red transmission and reception principle to switch on or off other appliances. It is a wireless mode of switching appliances to a desired state. When a number is pressed in the transmitter section, the receiver section decodes the signal and... Continue Reading
Abstract Compound housing is a housing arrangement that stemmed from cultural family living settings. Over the years, it has evolved to denote a group of different households that share a number of utilities including electricity. Electricity bills and payments are a concern in such living units due to the inability to split bills fairly. Previous... Continue Reading
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... Continue Reading
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...

ABSTRACT The conversion of an input AC power at a given frequency and voltage to an output power at different frequency and voltage can be obtained with static circuits called power converters, containing controllable power electronic devices. Various power converters have been developed to fulfill the requirements of the wind power generation.... Continue Reading
ABSTRACT PV modules exhibit a point at which its power is maximum; this point is called Maximum Power Point (MPP). Due to changes in weather conditions, the MPP changes and the PV module efficiency. Specifically, temperature and irradiance are the parameters that affect the solar panel characteristic properties. This project describes and... Continue Reading
Abstract —Radiation on BPLC caused by presence of high frequency communicating signals is discussed in this paper. The paper presents the derived mathematical model which expresses electric field radiation behavior of BPLC system. The model was developed using the combined numerical method of moment (MOM) and transmission line transient (TLT)... Continue Reading
ABSTRACT Automatic gate is one of most usefully thing to use in companies, colonies, collages, homes, and schools. There is some type to operate a gate such as a sliding on screw or on rack and pinion, piston operated, rotary. Design is available for some type of operation and it is most costly also When installation and maintenance cost is not... Continue Reading

Abstract This work involves the design and development of a digital signal detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in... Continue Reading
A temperature sensor is a device that reads the temperature of the surrounding and relays the temperature either in degrees Celsius or Kelvin. The LM335 temperature sensor (used in the experiment) gives out the temperature in degrees Celsius. It is calibrated to output the millivolt voltage reading in proportion to its units of measurement... Continue Reading
Abstract The project intends to increase vehicle operator awareness with the integration of a Low-Cost Driving Assistance system in older car models. Situational awareness during driving significantly reduces the number of road traffic accidents, as proved by literature. A 4-wheel mobile robot is used as the plant representing a vehicle for easier... Continue Reading
ABSTRACT This project present a practical demonstration of how to carryout the wiring of a two bedroom bungalow, using PVC conduit system. In recent times surface wiring is gradually giving way to conduit wiring where much of the cable are concealed. PVC pipes are used because of it cost friendliness, compared to metal conduit. In carryout this... Continue Reading

Commutation failures are very frequent dynamic events in high voltage dc (HVDC) transmission systems. Commutation failure is mostly observed at the inverter side of HVDC links, where large firing angles are used. The minimum value of the extinction angle required for the proper operation of a valve is specified by the valve manufacturer; however,... Continue Reading
