What scale model proves the initial concept?

About ceramics: Only can be optically opaque or semi-transparent. a) True b)-False

julia-pushkina [17]

Answer: True

Explanation: Ceramics have the property that when the band gap present between the atoms are larger than the light energy then the tend to become opaque because the light scattering is caused . They also show the property of being translucent when there are chances of the light to get a path through the surface of ceramic so they get the light at some parts e.g.porcelain .Therefore the statement given is true that ceramics can be optically opaque or semi-transparent(translucent).

3. In the text, we described a multithreaded file server, showing why it is better than a single-threaded server and a finite-st

NemiM [27]

Answer and Explanation:

• 1 thread awaits the incoming request

• 1 thread responds to the request

• 1 thread reads the hard disk

A multithreaded file server is better than a single-threaded server and a finite-state machine server because it provides better response compared to the rest and can make use of the shared Web data.

Yes, there are circumstances in which a single-threaded server might be better. If it is designed such that:

- the server is completely CPU bound, such that multiple threads isn't needed. But it would account for some complexity that aren't needed.

An example is, the assistance number of a telephone directory (e.g 7771414) for an community of say, one million people. Consider that each name and telephone number record is sixty-four characters, the whole database takes 64 MB, and can be easily stored in the server's memory in order to provide quick lookup.

NOTE:

Multiple threads lead to operation slow down and no support for Kernel threads.

2. Ackermann's Function is a recursive mathematical algorithm that can be used to test how well a system optimizes its performan

oee [108]

The python program is an implementation of the Ackermann function that a system optimizes its performance of recursion.

As per the question,

Here is an implementation of the Ackermann function in Python:

def ackermann(m, n):

if m == 0:

return n + 1

elif n == 0:

return ackermann(m - 1, 1)

else:

return ackermann(m - 1, ackermann(m, n - 1))

# get input values for m and n from the user

m = int(input("Enter an integer value for m: "))

n = int(input("Enter an integer value for n: "))

# calculate and print the result of the Ackermann function

result = ackermann(m, n)

print("Ackermann ({},{}) = {}".format(m, n, result))

This implementation follows the logic described in the prompt, using a recursive function to calculate the result of the Ackermann function for the given values of m and n.

You are designing a system for a real-time application in which specific deadlines must be met. Finishing the computation faster

makvit [3.9K]

Answer / Explanation:

To proper understand the answers that is given to the question, we need to understand some basic terms that has been used in the question.

Energy: This can be refereed to as the quantitative property that is transferred to an object for the purpose of the object working or to heat up the object. It can also be referred to as conserved quantity that is energy can be converted from one form or state to another but cannot destroyed.

Power: This can be defined as the rate of doing work or transferring heat per unit time from one state to another. The SI Units of power is watt which is equal to one joule per second.

Hence, the formula that links energy and power is:

Energy = Power x Time

Now. referring back to the question (a) asking how much energy do we save if we execute at the current speed and turn off the system when the computation is complete: The answer is = 50%. That is 50% of the energy is saved.

(b) If we recall the formula for calculating energy,

we have:

Energy = 1 /2 Load x V²

Changing the frequency does not affect the energy.However, it affects the power.

So therefore, the new energy is 1 / 2 Load x ( 1/2 V)² ,

reducing it to about 1 /4 of the old energy.
