Recall that to multiply an m×n matrix by an n×k matrix requires m×n×k multiplications. The Google PageRank algorithm uses a square matrix that’s filled with non-zero entries when pages link to one another. Suppose we have m web sites cataloged: this is then an m×m matrix. Denote this matrix by P. P is then run through an iterative algorithm that takes j loops to complete (for 5 < j < 100), and each step of this loop an m×m matrix is multiplied by P.

a. mj log m
b. m^2
c. m^3
d. m^4
e. m^2j^2
f. m^2log m

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
