5 - In this question, you will implement and simulate a simple receiver. a) First, using MATLAB, generate a number of random 11-bit data. Then design a transmitter that, upon receiving each of these 11-bit data, adds appropriate parity bits and finally sends them in the form of 15-bit data. Finally, you should store these 15-bit data in a file. Also, store the initial 11-bit data in a file for later validation purposes. b) Write a Verilog code that receives 15-bit data as input and, based on the parity bits, if the data reception process is correct, it places the 11-bit data on its output and sets the valid signal to high for one clock cycle. Otherwise, it discards the 15-bit data and increments the error output by one. c) Now, write a testbench that reads the 15-bit inputs from the file saved in Part A and applies them to the structure in Part B. Write the output of the Part B module to a file. Then, in MATLAB or the testbench, compare the output of your module with the initial 11-bit data and verify the functionality of your circuit. d) For a more comprehensive validation, introduce noise to the file containing the input data and examine the changes in the error signal.

e. When the air inside the sky lantern has reached a steady temperature of 360K determine the mass of the hot air inside the sky lantern. You may assume that the molar mass is still 29 grams/mole. f. [3 pts] Once the temperature of the air inside the sky lantern reaches 360K an addition amount of mass, $m_b$, is attached to the sky lantern and it floats perfectly still in the air. In the box at right, draw a FBD for the floating sky lantern. Treat the sky lantern, the air inside, and the hanging mass as a single object. g. Once the temperature of the air inside the sky lantern reaches 360K determine the buoyant force on the sky lantern (including the air inside it). h. Suppose the solid material of the sky lantern has a mass of 50 grams. What additional mass could the sky lantern support? Show all of your work.

6. Two balls collide in a glancing collision. The first ball, of mass 800. g, is moving at 30.0 cm/s in the positive x-direction. After the collision, it bounces off at an angle of 30.0° below the x-axis, with a speed of 15.0 cm/s. The second ball, of mass 500. g, is moving at 50.0 cm/s in the negative x-direction. After the collision, it's bounced off at an angle $\theta$ above the x-axis, with some speed $v_{2f}$. (a) How fast is ball 2 going after the collision? (b) What direction is it going? (c) Is this an elastic or inelastic collision?

The strength of a given aluminium alloy with no particles present is 20 MPa. The increase in the yield strength due to reinforcement by tiny particles is given by Equation (1). A metal matrix composite consists of an aluminium matrix phase reinforced with hard particles of SiC with a mean spacing of 5 microns. The increase in shear strength due to this dispersion strengthening is 40MPa. Calculate the size of the dispersion strengthening on the shear strength if the concentration of the particles is increased such that the inter-particle spacing decreases to 4 microns, then determine the total shear yield strength of the metal matrix composite. Finally, use your answer to determine the tensile strength of the material, and give this as your answer in MPa.\\ $\tau_d = \frac{Eb}{L}$ Eq (1)\\ $\sigma_y \approx 3\tau_y$ Eq (2)
