Q4. (24 pts) Design Optimization Consider the following design shown below. A B C The delays of block A, block B and block C, are $T_a$= 30ns, $T_b$= 20ns, and $T_c$= 10ns respectively at a supply voltage of V. The capacitances of each block are as follows: = $4C_a$, = $3C_b$ and = $2C_c$. As discussed in class, we can slow down the block by pipeline stages or parallelism we can reduce its supply voltage. Assume the following conversion between delay and voltage for all blocks is given below. Supply voltage for 2X delay = V/1.5 Supply voltage for 3X delay = V/2.0 Supply voltage for 6X delay = V/4.0 The pipelining or parallelism increases the capacitance of the blocks: Capacitance of 2 parallel blocks = 2.5 x Cblock Capacitance of 3 parallel blocks = 3.5 X Cblock Capacitance of a single pipeline stage (FF) = C a. (12 pts) For the original circuit, assume we add pipeline stages between A and B and B and C. What is the ratio of the new power of the system to the power of the original system given we want to have throughput constant? Note: The same voltage must be applied to all three blocks. If the pipelined stages are imbalanced, choose the voltage and frequency so that the throughput is maintained for the worst stage. b. (12 pts) Use parallelism individually on A and B to balance the pipelines. What is the ratio of the power of the system that uses balanced pipelines through parallelism to the power of the original system if we wish to keep throughput the same as the original system?

The manager of Falcon Co. publishing company is curious about the error rates of the typist in the secretarial pool. The managers belief is that the typist make more errors in the morning when they are not yet "warmed up", while some of the assistant managers believe the typist make more errors in the afternoon once fatigue has set in. Based on the samples below is there evidence of an increased error rate in the morning? n=33, x1=4.6364, x2=3.8182, s1=1.3652, s2=1.1847.BLANK #1: Is this a question involving MATCHED PAIR samples or INDEPENDENT samples? ***ANSWER "MATCHED PAIR" OR "INDEPENDENT" (WITHOUT THE QUOTATION MARKS)*** BLANK #2: Which type of distribution should be used to calculate the probability for this question? ***ANSWER "NORMAL", "T", OR "BINOMIAL" (WITHOUT THE QUOTATION MARKS)*** BLANK #3: Using the MORNING - AFTERNOON as your order of subtraction, which of the following options are the appropriate hypotheses for this question: ***ANSWER WITH THE CORRECT LETTER, WITHOUT ANY QUOTATION MARKS OR BRACKETS*** A) H0: μ1 - μ2 = 0 H1: μ1 - μ2 > 0 B) H0: μ1 - μ2 = 0 H1: μ1 - μ2 < 0 C) H0: μ1 - μ2 = 0 H1: μ1 - μ2 ≠ 0 D) H0: μD = 0 H1: μD > 0 E) H0: μD = 0 H1: μD < 0 F) H0: μD = 0 H1: μD ≠ 0 BLANK #4: What is the p-value of this sample? ***ANSWER TO 4 DECIMALS, BE SURE TO INCLUDE LEADING ZERO, EXAMPLE "0.1234"...NOT ".1234"*** BLANK#5: Based on this sample, at 1% level of significance is there evidence of an increased error rate in the morning? ***ANSWER "YES" OR "NO" (WITHOUT THE QUOTATION MARKS)***

Butanol is fed stoichiometrically with ethyl acetate into a 200 dm^3 CSTR to produce butyl acetate and ethanol. The reaction: CH3(CO)OC2H5 + C4H9OH ↔ CH3(CO)OC4H9 + C2H5OH is elementary and reversible. The reaction is carried out isothermally at 300K. At this temperature, the equilibrium constant is 1.08 and the specific reaction rate is 9 x 10^(-5) dm^3/(mol*s). The feed is fed at 0.05 dm^3/s and at a concentration of Cbut,o = 10 mol/dm^3. Calculate the equilibrium conversion.

If you're given a slant culture of a bacterial species A, arrange in order the steps you need to do in transferring microorganisms from that slant tube culture to a sterile nutrient broth using aseptic technique learned in this lab. Flame the neck of the broth tube and replace the cap and return tube to the rack. Sterilize the wet loop. Before closing, pass the mouth of the slant tube through the flame and replace the cap and return tube to the rack. Insert the loop to the broth tube and gently shake off some of the cells into the broth. Remove the loop. Hold the dry loop with your dominant hand like holding a pencil and sterilize it.
