In our discussion of tcp congestion control we implicitly assumed that the tcp sender always had data to send. consider now the case that the tcp sender sends a large amount of data and then goes idle (since it has no more data to send) at t1 . tcp remains idle for a relatively long period of time and then wants to send more data at t2. what are the advantages and disadvantages of having tcp use the cwnd and ssthresh values from t1 when starting to send data at t2 ? what alternative would you recommend? why?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
