A builder of houses has to order some supplies that have a waiting time for delivery Y uniformly distributed over the interval 1 to 4 days. Because she can get by without the supplies for 2 days, the cost of the delay is fixed at $100 for any waiting time up to 2 days. However, after 2 days the cost of the delay is $100 plus $20 per day for any time beyond 2 days. That is, if the waiting time is 3.5 days, the cost of the delay is $100 + $20(1.5) = $130. Find the expected value of the builder's cost due to waiting for supplies.
Suppose atT0 an 8-bit serial in / parallel out right shiftregister is set to value 11011010, and we want to shift in the data11101101. Show the contents of the register for each clock pulse upto next five clock pulses.
Give an intuitive explanation of why the maximum throughput, for small beta, is approximately the same for CSMA slotted Aloha and FCFS splitting with CSMA. Show the optimal expected number of packets transmitted after a state transmission in an Aloha..
A 2-V-peak sine wave signal is converted to digital form by a 12-bit ADC that has been designed to accept signals ranging from -5V to +5 V. (In other words, code words are assigned for equal increments of amplitude for amplitudes between -5V and ..
A 1000-W iron is left on the ironing board with its base exposed to the air at 20°C. The convection heat transfer coefficient between the base surface and the surrounding air is 35 W/m2 ?c °C. If the base has an emissivity of 0.6 and a surface are..
Write a program that asks the user to enter the numbers from 1 to 16 (in any order) and then display the numbers in a 4 by 4 arrangement, followed by the sums of rows, columns and diagonals.
Do the popular media approve of certain types of relationships and not others? 2. How do the media "define" friendship, love, and family?
a) if x(t) is even, show that its Fourier transform is real for all w (i.e: its imaginary part is identically 0) b)if x(t) is odd, show that its Fourier transform is imaginary for all w (i.e: its real part is identically 0)
find the noise temperature seen on Earth by treating the cascade of the background noise with the attenuation of the atmosphere. Do this for an ideal antenna pointing toward the zenith, and toward the horizon
Investigate and produce a report on the main different logic families and their requirements - Describe with the use of circuit diagrams the difference between TTL (74 series) and CMOS (4000) integrated circuits.
Formulate and solve a linear program for determining how many copies should be assigned to each printing firm to minimize the total cost of obtaining 75,000 acceptable quality reports.
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
The can's initial volume at 5 °C is 7.2 × 10-4 m3. The coefficient of volume expansion for aluminum is 69 × 10-6 (C°)-1. When the can and the liquid are heated to 87 °C, 7.0 × 10-6 m3 of liquid spills over.
