- 8086 Microprocessor lab. | 9 Discussion: Two word - wide unsigned integers are stored at the memory addresses OA00 H and OA02 H respectively, Write an instruction sequence that computes and stores their sum, difference, product, and quotient then Store these results at consecutive memory locations starting at address 0A10 H in memory. To obtain the difference, subtract the integer at OA02 H from the integer at OA00 H. For the division, divide the integer at OA00H by the integer at OA02 H. Use register indirect relative addressing mode to store the various result.Name two effects of negative feedback.The temperature of a catalysed exothermic reaction is being maintained at T1°C as it promotes generation of a particular product. It is proposed to control the temperature with a proportional only controller of gain Kc. The temperature dynamics of the reactor can be modelled as a mixture of a CSTR (1st order) and PFR (dead time) to changes either in inlet temperature, or in the heating/cooling jacket flowrate via Ke-tas Ts+1 i) Considering a change in inlet temperature show why a 1st order model for a CSTR and a dead time model for a PFR are appropriate.

Using the graph sketched in (a) above, estimate the velocity when t = 1.5 s Calculate the velocity of the function when t = 1.5 s by substituting to the velocity function.

- A stepper motor serves as the drive unit for the linear joint of an industrial robot. The joint Q4 must have an accuracy of 0.25 mm. The motor is attached to a leadscrew through a 2:1 gear reduction (2 turns of the motor for 1 turn of the leadscrew). The pitch of the leadscrew is 5.0 mm. The mechanical errors in the system (due to backlash of the leadscrew and the gear reducer) can be represented by a normal distribution with standard deviation = +0.05 mm. Specify the number of step angles that the motor must have in order to meet the accuracy requirement.8. What are the main stages of the FEM? 9. Make a sketch of a linear triangular finite element.
