Great care is taken to ensure that silicon boules are single crystalline with the highest possible purity. Describe how some adverse effects might manifest themselves if the processing was not handled with enough care; i.e., what makes single crystallinity and high purity so important?

Write a program that reads in characters until end of file. The program should count and print the number of characters, printable characters, vowels, digits, and consonants in the input. Use functions to check whether a character is a vowel, a consonant, or a printable character. Define and use macros to test if a character is a digit or a letter.

Use "do...while" loops to write a program that finds all prime numbers less than a specified value.

Use a switch statement to write a function that returns TRUE if a character is a consonant and returns FALSE otherwise.

Typical ultrasound consists of about 25 images extracted from a full-motion ultrasound examination. Each of these images consists of 512 by 512 pixels, each with 8 bit intensity information. a) What is the total number of bits in the 25 images?

b) Ideally the doctors would like to playback the ultrasounds at 30 frames per second. Assuming that when playing back each ultrasound frame is compressed by a factor of 0.8, what is the data rate required to play the ultrasound?

c) Consider now that this ultrasound needs to be viewed in real-time at a remote location using wireless communication. If the communication system has a signals to noise ration of 30dB and an overhead of 15%, what is the minimum bandwidth required for this communication.

d) Assume a practical error correction method is able to achieve a 75% of the above data rate. How many signal levels are required to achieve this data rate?

Can you explain the difference between overlapping and nonoverlapping in a moore sequence recognizer and mealy sequence recognizer?

Post a one paragraph summary about the way in which the limits of the speed of data transmission with Public Telephone Network System can affect you. ( please don't copy from the internet)

1. Transfer curves for three W’s of PMOS. Explain how PMOS W affects transfer curve.
2. Compare the simulated switching threshold with calculated one.
3. List the reasons for keeping PMOS wider than NMOS
4. Will the inverter response be same if instead of width you change length of PMOS instead of width

Database System Question

An automobile part trading company would like to store the following attributes for each
part in a database table:

PartNo: 10 bytes
Name: 30 bytes
UintMeasure: 5 bytes
UnitCost: 4 bytes
UnitPrice: 4 byes
QtyOnHand: 4 bytes
QtyOnOrder: 4bytes
PreferredSupplier: 30 bytes

Consider a disk with block size of 512 bytes and block pointer of 6 bytes long. Each record has a unique value of PartNo.
There are altogether 50,000 parts in the company.

Compute the following:

i) The number of file blocks required for storing the part records.

ii) The percentage of disk space saving achieved by implementing PartNo as primary index from implementing it as secondary index.

iii) The percentage of improvement on number of block accesses required for searching a product record based on PartNo’s value achieved by implementing PartNo as primary index from implementing it as secondary index.
