Suppose you are asked to design a highway control system where all the sensors share a 1 mbps link to the control center. each sensor transmits with probability 0.1. when it transmits, it can transmit either only numerical measurements at 0.1 mbps, or both numerical measurements and video at 1 mbps.

a. how many sensors can be supported using circuit switching if they transmit only numerical measurements? and what if they transmit both numerical measurements and video?
b. assume that sensors only transmit numerical measurements. how many sensors can be supported using packet switching such that the probability of exceeding the link capacity is no more than 0.005?
c. repeat b) but assume that sensors transmit both numerical measurements and video.
d. compare b-c) with a), at which transmission rate (0.1 mbps or 1 mbps) the sensors benefit more from packet switching

ok what is this for my man

there mad at that place

question: why should you take some time to reflect on the interview after it's over?

answer: to review what went well and learn how to do it better next time

explanation: you do this so incase you did bad on this interview you can reflect back on it and fix the mistakes you missed and when you do another interview you will do great because you reflected and studied what you did wrong

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in the first case the pronoun it probably refers to the car but it has not been mentioned before so we should replace it for the car. in doing so the statement becomes clear.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
