The processing company under study found out that the boiler was the key machine and needs artificial intelligence monitoring and control. It was simulated under Matlab software and oil level, and pressure and temperature were to be modelled and controlled using the programmable logic controller (PLC) with a fuzzy logic controller as the main brain of control. The company is for processing of fruits to produce juice.

The widespread of motor neurone weakness has become a major concern as a result of accidents, ageing, birth defects and other hereditary diseases. A huge number of paraplegics can barely do activities for themselves without assistance from helpers. This study seeks to develop an intelligent wheelchair that has an assistive lifting and multi-posture reclining mechanisms to help in elevating the user from sit to stand posture as well as recline the seat for angles between 90 and 180 degrees through use of hydraulic linear actuators. The design would incorporate strain gauge sensors on the lower back area of the seat to enable the user to stand by merely leaning forward; thereby decreasing the strain on the lower back seat to trigger the lift mechanism until the required height is attained. While pressing the sit button on the console would enable the lowering of the user to a sitting position. The wheelchair development would also enable intelligent mobility through use of ultrasonic sensors to detect obstacles and assist in the braking effort by the user. An economic analysis was done to assess the feasibility viability of the design for local production. Some user requirement validation was undertaken to establish the extent to which the design would satisfy the key requirements of the intended beneficiaries.
