Pretend you are a Genetech scientist working on a Cystic Fibrosis (CF) treatment. You want to create a mutant DNAse I in order to cut the DNA found in the mucus of CF patients. The goal is to decrease the viscosity of the mucus in the lungs through the chopping of DNA. Your project partner comes to you with the following proposals for mutating the DNAse protein. Which set of mutations would you move forward with if you could only choose one?

(40pt) For each of the following languages, prove whether it is regular or not. If it is, then: - construct a NDFSM for it - convert the NDFSM into a DFSM (include trap/dead states) - minimize the DFSM - convert one of the machines into a regular expression; give a simple regular expression; you may have to construct it directly if the machines give horrible expressions Show your work. If you can give directly a DFSM, then you don’t have to provide a NDFSM. If you provide directly the minimal DFSM, you still need to argue why it is minimal. L = {w ∈ {a, b} ∗ | w has aa and bb as substrings, but not aba} (do not give a reg. exp. here).

EXPERIMENT 1 1. PURPOSE To design and build a circuit using one NPN and one PNP transistor in a switch configuration. The circuit is used to turn a red LED on and off. It is not necessary to use the output from a digital device to switch the LED. Make use of a 10 V dc supply for this purpose. A red LED will obtain adequate brightness with 25 mA. Allow for 2V across the LED while operating. Take note of the polarity of the LED. 2. CIRCUIT DIAGRAM +10V T2 R2 R3 R1 T1 LED FIGURE 1 3. COMPONENTS 1 X NPN transistor with \(\beta = 250\) 1 X PNP transistor with \(\beta = 250\) 1 X red LED 3 X resistors APPARATUS 1 X 20 V dc supply 1 X bread board Few pieces of telephone wire 4. METHOD Calculate values for all resistors in the circuit diagram. Build the circuit onto a bread board. When the dc supply is turned on, the LED should be off. When the switch is pressed, the LED should turn on. When the switch is depressed, the LED should turn off. 5. RESULT 6. CONCLUSION 2

Assume that HASF furniture Inc., as described, currently purchases the chair cushions for its lawn set from an outside vendor for $15 per set. Modern Furniture's chief operations officer wants an analysis of the comparative costs of manufacturing these cushions to determine whether bringing the manufacturing in-house would save the firm money. Additional information shows that if Modern furniture's were to manufacture the cushions, the materials cost would be $6 and the labor cost would be $4 per set and that it would have to purchase cutting and sewing equipment, which would add $10,000 to annual fixed costs.\ Note: No need to enter currency symbol and comma and % just type numbers 2 decimal number and percentages (if needed) according to excel (for example: 10000 or 10.65) Required what amount company save if company make 10,000 cushions?
