3-15 Consider the 2-D rectangular region 0 < x 0, internal energy is generated at a constant rate gy (W/m?) and the region is subjected ‘to the follow- ing boundary conditions: The boundaries at x = 0 are maintained at a prescribed temperature f(y), the boundary at x = a is subjected to a prescribed heat flux q”(y) out of the solid, the boundary at y = 0 is main- tained at constant temperature T,, and the boundary at y = b dissipates heat by convection into a medium with fluid temperature T,, and with a heat transfer coefficient h. Formulate the problem using superposition for solution of T(x, y, t), such that each subproblem is in a solvable form. Formulation includes the simplified PDE or ODE and the corresponding boundary and/or initial conditions. Do not shift the temperature scale for any problems, and do not actually solve any of the subproblems, only formulate.

Task 3. 8 bit adder subtractor first create a new circuit, and call it "8-bit Adder/Subtractor". Then implement an 8-bit adder- subtractor circuit as outlined below. A7 B7 A6 B6 A5 B5 A4 B4 A3 B3 A2 B2 A1 B1 A0 BO 0 SUB FA FA FA FA FA FA FA FA Cout S7 S6 S5 S4 S3 S2 S1 SO Notes for understanding of the circuit above: In two-bit encoding, negation can be achieved by inverting a number and adding one (i.e., -A = ~A + 1). To subtract a number B from A, invert B, add 1 to it, then proceed to add that sum to A: A - B = A + ~B + 1 Therefore, in order to transform a normal adder into a subtractor, you need to invert the second operand (B) and add 1. Inverting is done using the XOR gates, and adding 1 is done using the carry-in. So, when the control signal SUB is 0, we have A = A B = B Cin = 0 And for SUB = 1 A = A B = ~B Cin = 1 Implement 8 bit Adder/Subtractor circuit in Logic Works and verify operation on 8 bit numbers.
