Transcript: Partial list of opcodes for the hypothetical machine shown above is given below:
1001 = Load AC from Memory; 1110 = Store AC to Memory; 0101 = Add to AC from
Memory; 0011 = Load AC from I/O; 0111 = Store AC to I/O; 0111 = Divide contents of AC
from Memory. In these cases, the 12 bit address identifies a particular I/O device. Write program to divide
content of Memory 6A0H by content of Memory 2A0H and send the result (assume no
remainder) to an output device connected at port 5A3H. Also show the program execution.
Assume that data read from 6A0H and 2A0H are 25 and 5 respectively.

Transcript: The inclined manometer in figure below contains Meriam red manometer oil (sg= 0.827). Assume the reservoir is very large. What should the angle θ be if each inch along the scale is to represent a change of 0.8 lb/ft²Â in gage pressure P_A?

Transcript: Given the signals Ci (i = 1, 2, 3….13) in following diagram, list the activation of control
signals in sequential order to find the average of at least three numbers stored in consecutive
locations of main memory. The result should be saved in any memory location at the end. You
can assume/introduce more registers and control signals for specific purposes and tasks. In that
case, please specify those at the beginning.

Transcript: Assume byte-addressable main memory has address size of 24 bits. For a 2-way-set-associative - mapped cache design, the following bits of the address are used to access the cache. Tag 13 bits set 7 bits Word 4 bits (i) What is the cache line size in bytes? (ii) How many entries does the cache have? (iii) What is the ratio between total bits required for such a cache implementation over the data storage bits? Starting from power on, the following byte-addressed cache references are recorded. Addresses: 0 4 32 64 128 256 512 1024 2014 0 4 32 (iv) How many blocks are replaced? (v) What is the hit ratio? (vi) Show the state of cache memory at the end (the cache lines containing blocks of main memory)

The transition graph for an NFA is shown in the following figure.

3. What's the regular expression of this language?
   
   

Here is NFA

Find the volume of a solid obtained by rotating the region bounded by the curves \(y\:=\:\sqrt{x}\) and \(y\:=\:x\) around the line \(x\:=\:2\)

The Ajax Corporation manufactures compressors for commercial air conditioning systems. A new compressor design is being evaluated as a potential replacement for the most frequently used unit. The new design involves major changes that have the expected advantage of better-operating efficiency. From the perspective of a typical user, the new compressor would have an increased investment of RM8,600 relative to the present unit, and an annual expense saving dependent upon the extent to which the design goal is met in actual operations.

Estimates by the multidisciplinary design team of the new compressor achieving four levels (percentage%) of the efficiency design goal, the probability and annual expense saving at each level are shown in Table Q4(b).

Based on a before-tax analysis (MARR = 18% per year, analysis period = 6 years, and salvage value = 0) and E(PW) as the decision criterion, is the new compressor design economically preferable to the current unit? Provide a single-state decision tree diagram with PW values for each level for the design alternatives.
