Consider a DASH system for which there are N versions of a video file (in an increasing order of quality) and N versions of a co

rresponding audio file (in an increasing order of quality). Suppose we want to allow the player to choose at any time any chunk of the N video versions and any of the N audio versions. a. If we create files so that the audio is mixed in with the video in a the same file, so server sends only one media stream at given time, how many files will the server need to store? b. If the server instead sends the audio and video streams separately and has the client synchronize the streams, how many files will the server need to store?

Answer: a) N² files. b) 2N files.

Explanation:

if an user can choose freeely both the video and the audio quality, if they are stored separately, but the user can download any mix of them as a single file, the server must store one audio version for each video version, so it will need to store NxN = N² files.

If, instead, the server can send the audio and video streams separately, so the user can choose one of the N video available, and one of the N audio versions, the server will need to store only N video files + N audio audio files, i.e. , 2 N files.

Cuando se creo argentina​
vekshin1

Answer:

Argentina se creó tras su independencia respecto de España el 9 de julio de 1816, tras 6 años de guerra por la independencia del país, donde líderes como Manuel Belgrano, Martín Miguel de Güemes y José de San Martín derrotaron a los españoles.

La unidad nacional de los argentinos, a su vez, se originó tras las invasiones inglesas de 1806 y 1807, y se consolidó tras la conquista de España por parte de los Bonaparte, que dio origen a la Revolución de Mayo de 1810, donde los argentinos decidieron imponer un gobierno propio.

Recall that through either photographic or computer technology, researchers can make a composite (or "averaged") face out of any
kow [346]

Answer:

People prefer composite faces.

Explanation:

If we take some face's picture, and we make it digital, we could make a composite or averaged face, and when we compare composite faces with originals pictures, people prefer the composite faces because there was symmetry in those faces.

For example:

There was a research where a digitalized student faces men and women, researchers make a composite face for every original, people prefer composite face against the original face.

You are given a string of n characters s[1 : : : n], which you believe to be a corrupted text document in which all punctuation
alexdok [17]

Answer: provided in the explanation section

Explanation:

Given that:

Assume D(k) =║ true it is [1 : : : k] is valid sequence  words or false otherwise

  • To determine D(n)

now the sub problem s[1 : : : k] is a valid sequence of words IFF s[1 : : : 1] is a valid sequence of words and s[ 1 + 1 : : : k] is valid word.

So, from here we have that D(k) is given by the following recorance relation:

D(k) = ║ false maximum (d[l]∧DICT(s[1 + 1 : : : k]) otherwise

Algorithm:

Valid sentence (s,k)

D [1 : : : k]             ∦ array of boolean variable.

for a ← 1 to m

do ;

d(0) ← false

for b ← 0 to a - j

for b ← 0 to a - j

do;

if D[b] ∧ DICT s([b + 1 : : : a])

d (a) ← True

(b). Algorithm Output

      if D[k] = = True

stack = temp stack           ∦stack is used to print the strings in order

c = k

while C > 0

stack push (s [w(c)] : : : C] // w(p) is the position in s[1 : : : k] of the valid world at // position c

P = W (p) - 1

output stack

= 0 =

cheers i hope this helps !!!
