Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

29. • Electronics uses various measuring instruments. The
mostly used measuring instrument is the Multitester
for it can check different values like voltage,
resistance and milliammeter.
30. • Multitester comes with two variants, the analog
multitester and the digital multitester.
Analog Digital
31. Analog multitester A tester that uses analog meter to read
the value of the component being tested.
Digital multitester A tester that uses digital display to reflect
the value of the component being tested.
Resistor A component that opposes the flow of
current.
Capacitor A component that stores energy.
Diode A component that allows current to flow in
only one direction.
Transistor A component used as switching and
amplifier.
Integrated Circuit(IC) A chip that have combination of
components inside and can do various
works.
33. Resistor color coding
• the process of getting the value of the resistor by the
color embedded to the carbon resistor.
• sometimes the resistor is somewhat higher or lower
with the color code value.
• resistor is still in good condition even if the value is
not the same value of the color code as long as the
value is within its tolerance.
35. PROCEDURE IN COLOR CODING THE VALUE OF
RESISTOR.
• Identify which of the color is the1st band of the
resistor. Take the resistor and see the color gold or
silver (tolerance). The tolerance must be at the right
side of the color set of the resistor when held. The
most left color of the resistor is the first band where
the start of reading takes place.
• *Take note you cannot see colors black, gold, silver
and no color in the first band.
36.
37. • Using the color coding table write down the value
found in a resistor with the responding color. The first
band gives the first number, the second band gives
the second number, the third band gives the
multiplier or number of zeroes, the fourth band
represents the tolerance.
38.
39.
40. • Write down the 1st and 2nd number then multiply it
with the multiplier.
• Wherein the 1st and 2nd number is 61 then multiply
it by 100. So we can get 6100, just copy the answer
and put ohm symbol (Ω) after the product and copy
the tolerance. So the value of resistor is 6,100 Ω ±5%.
41.
42. COMPUTING THE TOLERANCE OF THE RESISTOR
• The TOLERANCE is the range that determines the
good working value of a resistor. When a resistor is
not within the range of the computed tolerance value
of resistor is called OUT OF TOLERANCE.
43. Steps in getting the tolerance value of resistor.
• Get the value of the resistor.
• Get the tolerance value of the resistor. To get this
multiply the resistor's value with the tolerance (6100
x 0.05) = 305 so 305 Ω is the tolerance value. 5% is
equal to 0.05, 10% is equal to 0.1 and 20% is equal to
0.2.
44. • After getting the tolerance value. It is time to get the
maximum value of a resistor. Just add the resistor
value (6 100 Ω) and the tolerance value (305 Ω).
• 6100 Ω + 305 Ω = 6 405 Ω. So the maximum value of
the resistor is 6 405 Ω.
45. • After getting the maximum value, get the minimum
value of the resistor by subtracting resistor value ( 6
100 Ω ) and tolerance value ( 305 ).
• 6 100 Ω - 305 Ω = 5 795 Ω. So the minimum value of
the resistor is 5 795 Ω.
47. STEPS IN MEASURING RESISTANCE USING AN
ANALOG OHMMETER
• You must know to interpret the value of the scale.
• Values of each line per range in the scale
• 0 – 5= 0.2
• 5 -10 = 0.5
• 10 – 20 = 1
• 20 – 50 = 2
• 50 – 100 = 5
• 100 – 200 = 20
• 200 – 500 = 100 (if the line is shorter than the other, the value is 50)
49. • Set the proper range to be used in a certain resistor
value. The range that is used must be multiplied to
the interpreted value from scale.
For example: Interpreted value is 10
Range used is x 100
so the measured value is 1 000 (10 x 100)
50.
51. • Adjust the pointer to the infinite resistance reading,
after that adjust the zero-ohm adjustment knob to
the zero resistance reading in order to get a precise
reading. This process is also known as calibrating the
meter.
52.
53. • Connect the test probe to resistor’s terminal and
proceed to resistance measurements.
54. Color code the following and write it in your
activity sheets.
