The lift coefficient () is dimensionless.

The lift coefficient is a crucial concept in the world of aerodynamics, and it refers to the ratio of the lift force generated by an object to the dynamic pressure of the fluid flow around it. In other words, it measures the effectiveness of an object at producing lift.

The lift coefficient is an essential parameter in aircraft design and performance analysis. It determines the optimal wing shape, angle of attack, and other factors that affect lift. A higher lift coefficient means that an object can generate more lift, which is essential for aircraft to take off and stay in the air.

However, it's important to note that all objects' lift coefficients are not constant, and it varies depending on factors such as the shape, size, and speed of the thing and the properties of the fluid flow around it. Understanding and optimising the lift coefficient is crucial for achieving maximum performance and efficiency in aviation and other fluid dynamics fields.

Insert ones for the labels of the positive target

  • Implement code to update the labels , assuming you just inserted an "activate" audio clip.
  • In the code below, y is a (1,1375) dimensional vector, since .
  • If the "activate" audio clip ends at time step , then set and also set the next 49 additional consecutive values to 1.
    • Notice that if the target word appears near the end of the entire audio clip, there may not be 50 additional time steps to set to 1.
    • Make sure you don't run off the end of the array and try to update y[0][1375], since the valid indices are y[0][0] through y[0][1374] because .
    • So if "activate" ends at step 1370, you would get only set y[0][1371] = y[0][1372] = y[0][1373] = y[0][1374] = 1

Exercise 3 - insert_ones

Implement insert_ones().

  • You can use a for loop.
  • If you want to use Python's array slicing operations, you can do so as well.
  • If a segment ends at segment_end_ms (using a 10000 step discretization),
    • To convert it to the indexing for the outputs (using a step discretization), we will use this formula:
    segment_end_y = int(segment_end_ms * Ty / 10000.0)
