Briefly explain what are the following AIDC technologies for industry automation:

(a) the RFID technology,
(b) the Universal Product Code (UPC),
(c) 2-D stacked bar code, and
(d) Optical Character Recognition (OCR).
Give one possible ISE716 Spring 2020 3 application example of automation for each of the above mentioned AIDC technology.

Abrayton cycle operates with a regenerator on the air-standard with properties evaluated at 400 k. the tem- perature of the air entering the compressor is 350k while the temperature of the air exiting the compressor is 600 k. the temperature of the air entering the turbine is 1600 k. the overall cycle produced 600 kj/kg of net work out. assuming a regenerator effectiveness of 0.8, what is the temperature of the air before heat addition (combustion)? draw this process on a t - s diagram
