a) Engineering design generally involves five steps developing a statement of the problem and/or a set of specifications gathering information pertinent to the problem designing several alternatives and selecting the best one and testing and implementation the best design. How is ethical problem solving like this?
a) The space shuttle is an extremely complex engineering system. The more complex a system the harder it is to make a safe especially in a harsh environment such as outer space. Do you think that two accidents in 113 flights is an acceptable level of risk for an experimental system such as the shuttle Explain?
By substituting the value of x in the following, first compute y and then represent y in Radix and Diminished-Radix complement formats (for respective Radix),
iii (x)10 + (1011)2 = ( y )8
iv (x)10 × (15)8 = ( y )2
value of x is 49
By substituting the value of x in the following, compute y and z
i (x)10 + (35) 8 = ( y ) 2 = ( z ) 16
ii (x)10 × (1010110) 2 = ( y ) 4 = ( z ) 10
value of x is 49

Using a nano-chip technology an evil mad scientist discovers a way to enter and take control of the
minds and bodies of other individuals.
Demonstrate your knowledge of writing skills and creative writing and complete the above stated story.
Your story must include the following details:
How will the scientist inject the nano- chips in the bodies of other individuals?
What tasks will he ask the individuals to perform?
How the law enforcing agencies will stop the scientist in accomplishing his task?
A piezoelectric accelerometer has the following properties and inputs:
Axial acceleration = 10 g’s
Transverse acceleration = 3 g’s
Transverse sensitivity = 4%
What is the magnitude of the acceleration in g’s that the accelerometer measures in the axial direction?
Find the maximum of the function f = −2x5 +4.2x4 +2x3
- x
2 +20x − 5 in the range −8 ≤ x ≤
10 using the Particle Swarm Optimization method. Use 4 particles with the initial positions
x1 = −2, x2 = 0, x3 = 1, and x4 = 3.
Simulate a single-phase AC voltage controller and plot its voltage and current waveforms
using coding in the command window. The plot should be of minimum 300 dpi clarity.
Also include the FFT harmonic spectra of the current.
Simulate using MATLAB a single phase full bridge inverter driving an inductive load.
Represent the results appropriately in graphical form with detailed analysis and insights
into the results obtained. Also included in the results, normalized FFT of the inverter
output current.
