DESIGN AND FABRICATION OF A MOTORIZED CHAIN HACKSAW: This project is on the design and construction of an automatic power hacksaw machine for cutting of metal to different size and length with the help of hacksaw. The objective of this project is to save man power and time in cutting metals in order to achieve high productivity. It is a cutting machine with teeth on its blade used specially for cutting metals. The power to the hacksaw is provided by the motor...read more and download here

[3591]. AN ASSESSMENT OF THE PERFORMANCE OF MORTAGE INSTITUTE OF REAL ESTATE DEVELOPMENT (A CASE OF FEDERAL MORTAGE BANK OF NIGERIA IBADAN BRANCH): As it generally known that shelter is as important as food and it is one of the basic necessities of life for human being. As this result, the main motive of man is therefore to own a house on earth where he and his family will be secured and protected against any external forces...read more and download here

[3592]. DESIGN AND CONSTRUCTION OF ELECTRIC BLOWER FOR FURNACE: During furnace operation, air is the utility that should be available at all time in order to ensure a smooth and standardized operation. Supplying air manually will reduce productivity and more man hour to accomplish a given task. Thus, an electric blower was designed in this regard with an efficient electric motor as the driver. The suction conditions and other application data are appropriately used to calculate the design parameters such as: suction specific speed, the power input to the blower, the inlet and outlet velocity, the twisting moment of the impeller shaft...read more and download here

[3593]. ENHANCEMENT OF THE YIELD AND QUALITY OF PALM KERNEL OIL: By the end of the century palm kernel (PK) oil is forecast to rank fifth in volume of world trade in oils, only slightly behind coconut oil. PK oil received by Malaysian refiners is of good quality, typically below 2% in free fatty acids, and is easily refined. PK oil is fractionated to give a higher melting fraction (stearin) and a lower melting fraction (olein). The various processes used are described. PK oil, olein or stearin are also hydrogenated to give a range of products ranging in melting point from about 24 to 44°C. PK oil and olein are interesterified alone or in blends with a non‐lauric oil to give products with improved melting properties and utility...read more and download here

[3594]. DESIGN AND CONSTRUCTION OF A MOBILE PHONE DETECTOR USING 555 TIMER IC: This handy, pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile cell phone from a distance of one and-a-half meters. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc. It is also useful for detecting the use of mobile...read more and download here

[3595]. IMPLEMENTATION OF A SMART SURVEILLANCE CAMERA USING ESP32-CAM AND PYTHON-FLASK: This work is on a smart surveillance camera using ESP32 and python-flask. In recent times, we used surveillance cameras for monitoring and recording moments, but manual surveillance and real-time monitoring is one of the most important and challenging branches of computer vision, which has been widely applied in peoples’ life, such as monitoring...read more and download here

[3596]. DESIGN AND CONSTRUCTION OF A BATTERY LOW VOLTAGE ALARM SYSTEM: Sometimes there is nothing worse than losing all the charges on our device especially when you are in the middle of something very important. Usually this happens at the most inconvenient time probably when you are using device that have no low battery indicator. A low battery alarm system is used to indicate when a device’s battery is running empty. When the battery is low or dead, the system will start beeping...read more and download here

[3597]. DESIGN AND CONSTRUCTION OF A 400W AUDIO AMPLIFIER: This work is titled the design and construction of 400W power amplifier. Power amplifier is a device for increasing the audio power of a signal by use of an external energy source. It is design to meet up with the amplification demand in homes, offices, industries and especially in music industries. A 400W power amplifier amplifies low-power audio signals (signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain, While the input signal to an audio amplifier may measure only a few hundred microwatts, its output may be tens, hundreds, or thousands of watts...read more and download here

[3598]. DESIGN AND CONSTRUCTION OF AN ALL TERRAIN ROBOT: Due to the rapid progress in the field of robotics, it is a high time to concentrate on the development of a robot that can manoeuvre in all type of landscapes, ascend and descend stairs and sloping surfaces autonomously. This paper presents details of a prototype robot which can navigate in very rough terrain...read more and download here

[3599]. DESIGN AND CONSTRUCTION OF A 500W AUDIO AMPLIFIER: This work is titled the design and construction of 500W power amplifier. A power amplifier is a device for increasing the audio power of a signal by use of an external energy source. It is design to meet up with the amplification demand in homes, offices, industries and especially in music industries. A power amplifier amplifies...read more and download here

[3600].
