Hello, i'm israr from 8th semester eee. i chose automated railway gate control using plc (ge versamax) as my project. i used ir sensors to detect train and send signal to open the gate. so far in the input side there is no problem at all. but the output , that is a l293d driver controlling dc geared motors i don't know how to connect the l293d to the plc output. in l293d there 4 input terminals. 2 for each and you are suppoesed to give '0' that is a ground signal to i1 or i2 to operate in anti and clockwise respectively. but how do i give this ....etc

PART A
Simulation Exercises
Aim: To observe the effect of congestion by setting the parameters like, varying the queue size and page link bandwidth.
1. Simulate a three-node point-to-point network with a duplex page link between them. Set the queue size and vary the bandwidth and find the number of packets dropped.
Topology:-
Commands Used at Sender node and Receiver Node:
Sender:-
stcp –p 2000 –l 1024 1.0.1.2
Receiver:-
rtcp –p 2000 –l 1024
Results:
Case 1: set bandwidth to 10 Mbps and Queue size as 50

Manual gearbox 02T

Design and Function
With the new 02T 5/6-speed manual gearbox of the MQ200 series, Volkswagen has succeeded in developing an ultra-light twin-shaft gearbox. The housing is manufactured from magnesium. The gearbox can transmit up to 200 Nm of torque and is used throughout the Group in combination with various engines ranging from the A00 class to the A class. The final drive ratios and the ratios of the individual gears can be matched to the power outputs of the various engines. The type divers ....etc

The programmer devices requiredfor programming theelectrically programmable readonlymemories (EPROMs) are generallyexpensive. Here is a low-cost circuit toprogram binary data into 2716 and Priyank Mudgal 2732 EPROMs.The circuit uses timer NE555 (IC2)wired as a monostable. When push-toonswitch S1 is pressed, IC2 generatesa 50ms pulse, which is given to the programpin 18 of the ZIF SOCKET throughswitch S2. EPROM is inserted into theZIF SOCKET for programming.
