The following is a toy web graph with hubs C, D, E and F, and authorities A, B,

and G.

(a) Show the (hubs and authorities) values obtained by running two rounds of the hubs

and authorities algorithm on this network. Show the values both before and after

the final normalization step, in which we divide each authority score by the sum of

all authority scores, and divide each hub score by the sum of all hub scores. You

should express the normalized scores as fractions rather than decimals.

(b) Suppose you wish to add a new authority web site X to the network and want it

to have as high an authority score as possible. You also have the ability to create

another new hub web site Y which we can use as a hub to elevate the score of X.

Consider the following three options:

You add a link from Y to X (and add no other new links).

You add a link from Y to A and X (and no other links).

You add a link from Y to A, B, G and X (and no other new links).

For each option, show the normalized authority values that each of A, B, G and X

obtain when you run 2-steps of hub-authority computation on the resulting network

(as you did in part (a)). Which option gives X the highest (normalized) score?

Operations Management – powerpoint presentation – Chose a multinational (global) company that is of interest to you (e.g. Texaco, American Airlines, Nestle, etc). Prepare a detailed research on the company. • Provide a (brief) background on the company. • Identify its product/s • Briefly mention the various strategies utilized by the company( corporate strategies, international strategies, operational strategies ect..)•Detailed analysis of the company’s Operations; and the Operation Management Department. (reference can be made to the ten OM decisions where necessary; this section should be the core of the presentation).
