Why could such a data structure be much smaller than a flat page table? (h) [4] Does a TLB miss always lead to a page fault? Why or why not?

Answers

Answer 1

We have 2^48 pages per person. The number of physical pages is 2^16.. 48 bits of VPN are mapped to 16 bits of PPN. The PTE size is 2B. The page table size is 2^49 B.

What are the steps to calculate pages per person, physical pages, VPN ,PTE size and the table size?

We know that;

Virtual Address = 64bits

Virtual Address Space = 2^Virtual Address = 2^64B

Physical Address Space = 4GB  = 4 X 2^30 B = 2^32 B

Physical Address = log_2(Physical Address Space )  = log_2(2^32)

                             = 32 * log_2(2) = 32 bits.

Page size = 64KB =2^16 B

a) No of Virtual Pages = Virutal Address Space/PageSize

                                      =  2^64B / 2^16 B = 2^48

b) NoOfPhysicalPages = PhysicalAddressSpace/PageSize

                                      =  2^32 B / 2^16 B = 2^16

c) VPN (in Bits) = log_2(NoOfVirtual Pages)   = log_2(2^48) = 48

    PPN(inBits)=log_2(NoOfPhysicalPages)=  log_2(2^16) = 16

Thus 48 bits of VPN are mapped to 16 bits of PPN.

d) PTE( Page Table Entry) holds the Physical Page Number of given Virtual Page along with many information about the page.

PTEsize = PPN(inBits) = 16 bits = 2B

e) Flat page table is single level page table. A page table contains the Physical Page number for a given page number. It helps in the translation of Vitual Address to Physical Address.

PageTableSize = NoOfVirtualPages*PTEsize = 2^{48}*2B = 2^49

Recall that a contiguous subarray is all of the elements in an array between indices

and
j
, inclusive (and if
j we define it to be the empty array). Call a subarray is nearly contiguous if it is contiguous (i.e. contains all elements between indices
i
and
j
for some
i,j
) or if it contains all but one of the elements between
i
and
j
. For example, in the array
[0,1,2,3,4]
, -
[0,2,3]
is nearly contiguous (from 0 to 3 , skipping 1 ), sum is 5 -
[0,1,2,3]
is nearly contiguous (because it is contiguous from 0 to 3 ), sum is 6 . -
[2,4]
is nearly contiguous (from 2 to 4 , skipping 3 ), sum is 6 . - [3] is nearly contiguous (because it is contiguous from 3 to 3 ), sum is 3 . - [] is nearly contiguous (because it is contiguous from 1 to 0 ), sum is 0 . -
[0,2,4]
is not nearly contiguous (because you'd have to remove two elements). The sum of a nearly contiguous subarray is the sum of the included elements. Given int [] A, your task is to return the maximum sum of a nearly contiguous subarray. For example, on input
[10,9,−3,4,−100,−20,15,−5,9]
your algorithm should return 24 (corresponding to
i=
6,j=8
and skipping the
−5
). (a) Define one or more recurrences to solve this problem. (b) Give English descriptions (1-2 sentences each should suffice) for what your recurrences calculate. Be sure to mention what any parameter(s) mean. (c) How do you caclulate your final overall answer (e.g. what parameters input to which of your recurrences do you check). (d) What memoization structure(s) would you use? (e) What would the running time of your algorithm be (you do not have to write the code). Justify in 1-3 sentences.

Answers

(a) One possible recurrence to solve this problem is:

Let f(i, j) be the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

f(i, j) = max(f(i, j-1), f(i, j-2) + A[j])

This recurrence calculates the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The subarray does not include the element at index j. In this case, the maximum sum is the same as the maximum sum ending at index j-1.

The subarray includes the element at index j, but skips the element at index j-1. In this case, the maximum sum is the sum of the elements ending at index j-2 plus the element at index j.

(b) Another possible recurrence to solve this problem is:

Let g(i, j) be the maximum sum of a contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

g(i, j) = max(g(i, j-1) + A[j], A[j])

This recurrence calculates the maximum sum of a contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The maximum sum of the subarray includes the element at index j. In this case, the maximum sum is the sum of the maximum sum ending at index j-1 plus the element at index j.

The maximum sum of the subarray does not include the element at index j. In this case, the maximum sum is simply the element at index j.

(c) To calculate the final overall answer, we can input the values 0 and n-1 into both recurrences, where n is the length of the array A. This will give us the maximum sum of a nearly contiguous subarray that starts at the beginning of the array and ends at the end of the array.

(d) To implement these recurrences using memoization, we can use a two-dimensional array to store the calculated values of f and g. The array can be initialized with values of 0 for all indices, and then we can fill in the values starting from the bottom right corner and working our way towards the top left corner.

(e) The running time of this algorithm would be O(n^2), because we need to calculate the values of f and g for every possible pair of indices i and j. This requires O(n^2) time in the worst case.

Answer:

Explanation:

1). The MAX function in Microsoft Excel is used to find the maximum value in a range of cells. For example, if you have a range of cells A1:A10 containing a set of numbers, you can use the formula "=MAX(A1:A10)" to find the maximum value in that range.

2). The MIN function in Microsoft Excel is used to find the minimum value in a range of cells. It works in a similar way to the MAX function, but returns the minimum value instead of the maximum value.

3). The AVERAGE function in Microsoft Excel is used to calculate the average of a set of values. It takes a range of cells as input and returns the mean of the values in that range.

4). The INT function in Microsoft Excel is used to round a number down to the nearest integer. It takes a number as input and returns the integer part of the number.

5). The POWER function in Microsoft Excel is used to calculate the value of a number raised to a certain power. It takes two arguments: the base number and the exponent. For example, the formula "=POWER(2,3)" returns 8, because 2 raised to the power of 3 is 8.

An expression is a syntactic component of a programming language in computer science that can be valued through evaluation. It is a combination of one or more constants, variables, functions, and operators that the programming language deciphers (in accordance with its specific rules of precedence and of association) and computes to create ("to return," in a stateful environment), another value.

Evaluation is the term used to describe this action for mathematical expressions. In straightforward settings, the resulting value typically belongs to one of several primitive types, such as a numerical, string, boolean, complex data type, or other types. Statement, a syntactic entity with no value, is frequently contrasted with expression (an instruction).

How to isolate a single heartbeat in audio using the Librosa library?


We have collected various samples of heartbeat data with different cardiovascular diseases. Some examples of our dataset are uploaded here.


We would like to use Librosa to identify the starting/ending point of each heartbeat in the file. The goal, in the end, is to create a program that will take in a heartbeat file, and and output just one beat. What would be the best way to go about it?

Answers

Answer:

To isolate a single heartbeat in audio using the Librosa library, you can follow these steps:

Load the audio file into memory using the librosa.load() function. This function returns a tuple of the audio data as a NumPy array and the sample rate of the audio.

Use the librosa.onset.onset_detect() function to detect the onsets (i.e., the starting points) of the heartbeats in the audio data. This function returns a NumPy array of frame indices where onsets were detected.

Use the librosa.frames_to_samples() function to convert the frame indices to sample indices. This will give you the sample indices in the audio data where the heartbeats start.

Identify the sample indices where the heartbeats end by finding the difference between the starting indices of successive heartbeats. You can do this by subtracting the starting indices of the heartbeats from one another.

Use the NumPy slicing operator (i.e., []) to extract the samples corresponding to a single heartbeat from the audio data. For example, to extract the samples corresponding to the first heartbeat, you can use the following code:

suppose that an adversary, eve, creates a public and private key and tricks bob into registering pke as a trusted certificate authority (that is, bob thinks eve is a trusted certificate authority). assume that alice is a web server and bob a client and they connect to one another using ssl/tls. show a man in the middle attack allowing eve to listen in on all communication between alice and bob even if alice and bob use ssl/tls and even if alice (the server) has a certificate from a real certificate authority (alice does not trust eve as a ca).

Answers

Note that in a man-in-the-middle (MITM) attack, Eve acts as an intermediary between Alice and Bob, allowing her to intercept and potentially modify their communication.

What is a Man in the Middle Attack?

A man-in-the-middle (MITM) attack occurs when a perpetrator inserts himself into a dialogue between a user and an application, either to eavesdrop or to mimic one of the parties, giving the impression that a regular flow of information is taking place.

Here's how the attack could work:

Eve creates a public and private key and tricks Bob into registering PKE as a trusted certificate authority.

Alice and Bob establish an SSL/TLS connection using certificates from a real certificate authority (CA).

Eve intercepts the connection between Alice and Bob and establishes a separate SSL/TLS connection with each of them using her own certificate from PKE.

Bob trusts PKE as a CA, so he accepts Eve's certificate as valid.

Alice, however, does not trust PKE as a CA, so she may reject Eve's certificate. To bypass this, Eve can present Alice with a forged certificate from a real CA that Alice trusts.

Once Alice accepts the forged certificate, Eve has successfully established separate SSL/TLS connections with both Alice and Bob.

Eve can now intercept and potentially modify the communication between Alice and Bob, even though they are using SSL/TLS and have certificates from a real CA.

It's important to note that SSL/TLS and certificates from a real CA can still provide a high level of security against MITM attacks, but it is important for clients to carefully verify the identity of the certificate issuer and to ensure that they are not accepting forged certificates.

Answers

An absolute path is used to specify the complete precise file path, for instance, D:\http\project\lib\file.php. A relative path, on the other hand, is based on the script's location in the current working directory.

Comparing absolute and relative paths?

A relative path identifies a file's location in relation to the active (working) directory*. The distance from the root directory is specified by an absolute path. Relative file paths are frequently used while learning to access data files through programming.

What characteristics make a path an absolute path?

Any file in Windows can have its absolute path found by right-clicking it and selecting Properties. Look at the "Location:" entry in the file properties, which is the path to the file, first.

Which sentence below provides a minor supporting detail? 5 of 75 of 7 Items11:37FeatureThe Old Eagle TreeJohn ToddIn a distant field stood a large tulip tree, apparently of a century's growth, and one of the most gigantic. It looked like the father of the surrounding forest. A single tree of huge dimensions, standing all alone, is a sublime object.On the top of this tree, an old eagle, commonly called the "Fishing Eagle," had built her nest every year, for many years, and, undisturbed, had raised her young. A remarkable place to choose, as she procured her food from the ocean, and this tree stood full ten miles from the seashore. It had long been known as the "Old Eagle Tree."On a warm, sunny day, the workmen were hoeing corn in an adjoining field. At a certain hour of the day, the old eagle was known to set off for the seaside, to gather food for her young. As she this day returned with a large fish in her claws, the workmen surrounded the tree, and by yelling and hooting, and throwing stones, so scared the poor bird that she dropped her fish, and they carried it off in triumph.The men soon dispersed, but Joseph sat down under a bush nearby, to watch, and to bestow unavailing pity. The bird soon returned to her nest, without food. The eaglets at once set up a cry for food, so shrill, so clear, and so clamorous that the boy was greatly moved.The parent bird seemed to try to soothe them; but their appetites were too keen, and it was all in vain. She then perched herself on a limb near them, and looked down into the nest in a manner that seemed to say, "I know not what to do next."Her indecision was but momentary; again she poised herself, uttered one or two sharp notes, as if telling them to "lie still," balanced her body, spread her wings, and was away again for the sea.Joseph was determined to see the result. His eye followed her till she grew small, smaller, a mere speck in the sky, and then disappeared. What boy has not thus watched the flight of the bird of his country!She was gone nearly two hours, about double her usual time for a voyage, when she again returned, on a slow weary wing, flying uncommonly low, in order to have a heavier atmosphere to sustain her, with another fish in her talons.On nearing the field, she made a circuit round it, to see if her enemies were again there. Finding the coast clear, she once more reached the tree, drooping, faint, and weary, and evidently nearly exhausted. Again the eaglets set up their cry, which was soon hushed by the distribution of a dinner, such as, save the cooking, a king might admire."Glorious bird!" cried the boy, "what a spirit! Other birds can fly more swiftly, others can sing more sweetly, others scream more loudly; but what other bird, when persecuted and robbed, when weary, when discouraged, when so far from the sea, would have done this?"Glorious bird! I will learn a lesson from thee to-day. I will never forget hereafter, that when the spirit is determined it can do almost anything. Others would have drooped, and hung the head, and mourned over the cruelty of man, and sighed over the wants of the nestlings; but thou, by at once recovering the loss, hast forgotten all."I will learn of thee, noble bird! I will remember this. I will set my mark high. I will try to do something, and to be something in the world; I will never yield to discouragements."QuestionWhat effect do the eagle's actions have upon Joseph?ResponsesA He is appalled by the cruelty shown by so many creatures, human and animal alike.He is appalled by the cruelty shown by so many creatures, human and animal alike.B He finds the eagle's behavior well-meaning but ultimately pointless.He finds the eagle's behavior well-meaning but ultimately pointless.C He is inspired always to strive to do his best in life, and never to back down.He is inspired always to strive to do his best in life, and never to back down.D He feels angry at the injustice done, and depressed about how evil triumphs over good.He feels angry at the injustice done, and depressed about how evil triumphs over good.Skip to navigation before an internet user can access a demilitarized zone (dmz), extranet, or private network resource, it first encounters an entity that is sturdy enough to withstand any sort of attack. what is this entity called? what is the probability of rolling a six sided die six times and having all numbers from 1 through 6 appear once in any order? which of the following is an example of a negative externality? group of answer choices bae's company has a decrease in profits when the demand for its product falls. rita gains weight while she is on vacation because she eats more than normal. when fazio parks his big truck at the grocery store, people in the cars on each side of his parking space have a hard time opening their car doors. raul loses weight because he wants to feel better, but the weight loss means that he needs new clothes.
