for which there is an institutional network connected to the Internet. Suppose that the average object size is 850,000 bits and that the average request rate from the institution’s browsers to the origin servers is 16 requests per second. Also suppose that the amount of time it takes from when the router on the Internet side of the access link forwards an HTTP request until it receives the response is three seconds on average (see Section 2.2.5). Model the total average response time as the sum of the average access delay (that is, the delay from Internet router to institution router) and the average Internet delay.For the average access delay, use Δ/(1 – Δ·β), where Δ is the average time required to send an object over the access link and β is the arrival rate of objects to the access link.Find the total average response time.Now suppose a cache is installed in the institutional LAN. Suppose the miss rate is 0.4. Find the total response time

Answers

Answer 1

The total average time required to send an object over the access link and β is the arrival rate of objects to the access link is 3.349 seconds

Elaborating the problem:

The average access delay, use δ/(1 − δβ)

where :

δ is the average time required to send an object .

β is the arrival rate of objects to the access link.

a) Total average response time:

δ = 850,000 bits / 16000000 bps = 0.0531 Sec

δβ = 0.053 sec/request × 16 request/sec = 0.848

δ/(1 − δβ) = 0.0531/(1-0.848)

= 0.0531/ 0.152

= 0.349

Total average response time= 0.349+3 = 3.349 Sec

b) Total response time

miss rate =0.4

miss rate + hit rate = 1.0 (100%)

hit rate = 1.0 - 0.4 = 0.6

Since 60% of requests are fulfilled within the institutional Network, the traffic intensity on the access link is reduced by 60%, resulting in an average access delay of  0.0531 / (1-0.349 ×0.848)

= 0.0531/(1-0.2959)

= 0.0531/0.7

= 0.075 seconds

When the cache fulfills the request, which has a probability of 0.6, the response time is nearly zero.

The average response time is 0.075+ 3 seconds.

= 3.075 seconds ( which happens 40 % of the time)

So average response time = 0.6 × 0 sec + 0.4 × 3.075 sec

= 1.23 seconds

Thus the average response time reduced from 3.349 seconds to 1.23 seconds.

A secret team of programmers is plotting to disrupt the programming language landscape and bring punched cards back by introducing a new language called Punched Card Python that lets people code in Python using punched cards! Like good disrupters, they are going to launch a viral campaign to promote their new language before even having the design for a prototype. For the campaign, they want to draw punched cards of different sizes in ASCII art.
The ASCII art of a punched card they want to draw is similar to an R×CR×C matrix without the top-left cell. That means, it has (R⋅C)−1(R⋅C)−1 cells in total. Each cell is drawn in ASCII art as a period (.) surrounded by dashes (-) above and below, pipes (|) to the left and right, and plus signs (+) for each corner. Adjacent cells share the common characters in the border. Periods (.) are used to align the cells in the top row.
For example, the following is a punched card with R=3R=3 rows and C=4C=4columns:
..+-+-+-+
..|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
There are more examples with other sizes in the samples below. Given the integers RR and CC describing the size of a punched card, print the ASCII art drawing of it as described above.

Agile only uses a small amount of requirements documentation, which is not true of the agile methodology.

The Agile approach is an iterative, incremental development methodology which focuses on collaboration and customer satisfaction rather than on detailed documentation and planning. It is used to develop software in an iterative manner over a series of short cycles, known as sprints. Agile does not require detailed requirements documentation, instead, requirements are captured as user stories which define the functionality desired by the customer. User stories are usually written on index cards and discussed with the customer during sprint planning. The Agile method does not require that each user story have very detailed and in-depth requirements, though these may be defined if desired.

The beam has a weight of 700lb. Determine the shortest cable ABC that can be used to lift it if the maximum force the cable can sustain is 1500lb.

Answers

The cable that is attached exactly above the centre of gravity of the beam and has the length L = sqrt(x2 + h2) = sqrt((W/F)2) = sqrt(0.5) sqrt(W) = sqrt(700) sqrt(0.5) 18.7 ft. is the shortest cable that may be used to raise the beam.

What is the formula for beam weight?

The standard weight is determined as follows: G is equal to L * mweight, where L is the length of the beam determined as the separation between the extreme points of the beam body measured along the direction of the beam axis, with all features except holes taken into consideration.

We may express L2 in terms of x and F using the equations above as follows:

L² = x² + h²

= x² + (T/F)²

Substituting T = W + F, we get:

L² = x² + ((W+F)/F)²

Expanding and simplifying, we get:

L² = x² + (W/F)² + 2W/F + 1

d(L²)/dx = 2x

Setting this equal to zero, we get:

x = 0

This tells us that the minimum value of L² is obtained when x = 0, which means that A and B are vertically aligned. In other words, the cable should be attached directly above the center of gravity of the beam.

When we apply the derivative to F, we obtain:

d(L²)/dF = 2(W/F)² - 2W/F²

Setting this equal to zero, we get:

F = sqrt(2W)

Substituting W = 700 lb, we get:

the two wires are connected together at a. if the force p causes point a to be displaced horizontally 2 mm, determine the normal strain developed in each wire.

Answers

The normal strain developed in each wire, Strain = ΔL / L = 4 mm / L. The factor of (2 mm / L) in the denominator is due to the horizontal displacement of point A being proportional to the length of the wire.

What is Normal Strain?

The normal strain in a wire can be calculated with given formula:

Strain = ΔL / L.

where ΔL is the change in wire-length and L is the original wire-length.

In this case, since the two wires are connected together at point A, they will experience the same amount of strain.

To find the strain in each wire, we first need to find the change in length of each wire due to the horizontal displacement of point A.

Let's assume that the length of each wire is L.

When point A is displaced horizontally by 2 mm, the change in length of each wire can be calculated as:

ΔL = 2 * (L / 2) * (2 mm / L) = 4 mm

Strain = ΔL / L = 4 mm / L.

portfolio assessment emphasizes the instructional environment with a focus on the outcomes of learning. which of the following statements is correct? portfolio assessment

Answers

A sort of ongoing assessment known as curriculum-based assessment (CBA) involves periodic evaluation of a student's daily performance in connection to the material being taught.

It gives an indication of a student's curriculum progress and whether such development is sufficient. The system, quizzes, writing projects, and other evaluations that instructors regularly give their students in the classroom are the ones that are most effective for directing changes in student learning. Because they are directly related to the learning objectives in the classroom, teachers have confidence in the findings of these evaluations. The three definitions have one thing in common: a learning impairment is a dysfunction in one or more fundamental psychological functions that may show up as a poor aptitude in some learning domains, like reading.

*Exponential
*Linear
*Inverse
(Continues on)
so that when concentration increases, absorbance ___
Choose:
*Does Not Change
*Decreases
*Increases

Answers

The relationship between absorbance of light by a solution and its concentration should be linear according to the Beer-Lambert law And when the concentration of the absorbing species in a solution increases, the absorbance of the solution also increases.

What is Beer-Lambert law?

According to the law, absorbance is directly proportional to the concentration of the absorbing species in a solution, provided that the path length of the light through the solution is constant.

Mathematically, the relationship between absorbance and concentration is expressed as A = ɛcl, where A is the absorbance, ɛ is the molar absorptivity or extinction coefficient of the species, c is the concentration of the species, and l is the path length of the light through the solution.

The density of a cylinder having mass m, diameter D, and L is (4m)/pi*D^2*L. Assume that m, D, and L have the following uncertainties:
rho= 1.699 ± 0.010 kg (95%)
D = 0.050 ± 0.001 m (95%)
L=0.0100 ± 0.001 m (95%)
Estimate the uncertainty interval for the density at 95%
probability.

Answers

Using the formula for density, we calculate the nominal value of density as 1354.74 kg/m^3.

Using the rules of error propagation, we estimate the uncertainty interval for density at 95% probability to be (1353.44, 1356.04) kg/m^3.

Therefore, the density of the cylinder is estimated to be (1354.74 ± 1.30) kg/m^3 at 95% probability.

What are the variables needed to calculate the density of a cylinder?

Sure, here's what you need to know to calculate the density of a cylinder:

The density of a cylinder is determined by two variables: the mass and the volume. The mass is the amount of matter contained in the cylinder, while the volume is the amount of space it occupies. To calculate the density, divide the mass by the volume.

For example, if a cylinder has a mass of 10 kg and a volume of 0.5 m3, its density would be 20 kg/m3.

of the following motors, the one most likely before to have 15 or 18 motor leads is the a. single-phase capacitor-start motor b. 120 shaded-pole motor c. 480V three-phase squirrel cage motor d. 2,400V three-phase motor

Answers

While 480V three-phase squirrel cage motors may have more leads, they are normally in multiples of three, while single-phase capacitor-start motors and 120V shaded-pole motors typically have fewer leads.

What is a capacitor, exactly?

A two-terminal electrical device known as a capacitor is capable of storing energy in the form of an electric charge. It consists of two electrical wires that are a set distance apart from one another. The space between the conductors can be filled with vacuum or a dielectric, an insulating material.

The motor with the highest likelihood of having 15 or 18 motor leads is the 2,400V three-phase motor.

Typically, three-phase motors have leads that are a multiple of three (e.g. 3, 6, 9, 12, etc.). 36 windings on a 2,400V three-phase motor leads that could be split into three-piece sets to create different phases for the motor windings. Therefore, compared to the other types of motors indicated in the question, it is more likely to have 15 or 18 motor leads.

We then plot the water content on the y-axis and the number of blows (N) on the x-axis. The graph should look like this:

N  | 0 | 12 | 24 | 32 | 48

Water Content | 0.1 | 0.125 | 0.125 |

What is plot ?

Plot is the order of events that make up a story. It is the sequence of events that unfold in a story, usually presented in chronological order. Plots generally include a series of conflicts and resolutions that lead to a climax, which is the most intense point of the story. Plot also includes the setting and characters that drive the story forward.

A) Draw the Flow Curve and Obtain the Liquid Limit:

To draw the flow curve, we need to calculate the water content for each trial. The water content for each trial is calculated as the difference between the wet and dry weight of the soils plus the pan divided by the weight of the soils plus the pan.

Trial 1: Water content = (5.2-4.2)/(5.2+1.6) = 0.1

Trial 2: Water content = (4.35-3.55)/(4.35+1.4) = 0.1

Trial 3: Water content = (5.4-4.25)/(5.4+1.4) = 0.125

Trial 4: Water content = (4.4-3.5)/(4.4+1.4) = 0.125

We then plot the water content on the y-axis and the number of blows (N) on the x-axis. The graph should look like this:

N  | 0 | 12 | 24 | 32 | 48

Water Content | 0.1 | 0.125 | 0.125 |
