How do you define a function that tests if a number is even
using lambda calculus? The function should return true if the
number is even, and false otherwise.
Using Java, Explain how to implement a functional interface
using a lambda expression. You may include small sections of code
to illustrate your explanation.
Standardization
Goal: Perform the transformation on validation and test sets in
a right way The following code shows two ways to standardize
validation and test sets (here is only shown on a test set).
1- Run the following code to see the values of X_test_std1 and
X_test_std2
2- Re-apply standardization using StandrdScaler from
scikit-learn
3- Assuming the StandardScaler result is the correct
transformation, is the following statement correct?
"We should re-use the parameters estimated from the training
set to transform...
2. Convert the following infix form expression into the postfix
form expression by using a stack:
A+(B*(C-D)+E)/F-G*H
Show the stack after each push/pop.
Find All the following Laplace Transformations once using the
definition of Laplace Transformation and then using the memorized
Laplace Table relationships:
L[sin(ω*t)]
L[(e-5t)cos(6t)]
L[(e-5t)(t2)]
Using Calculus, calculate the elasticity of the following demand
functions. After that, calculate the elasticity for the points (1,
3) and (2, 2).
The first coordinate of the points above is Q, the second is
Price.
(1) Q = 10P ^ (-4)
(2) Q = 10 - P
3. Solve the following differential equations by using LaPlace
transformation:
2x'' + 7x' + 3x = 0; x(0) = 3, x'(0) = 0
x' + 2x = ?(t); x(0-) = 0
where ?(t) is a unit impulse input given in the LaPlace
transform table.
Design an IIR digital filter based on the bilinear
transformation method using the following transfer function as a
reference (use three decimal places of precision for your
response):
H (s) = 5 / (s ^ 2 + 1.1s +5)
The digital filter must have a resonant frequency at wr = pi /
3
a) Calculate H (z)
b) Find the correctly simplified difference equation of the
designed system.
c) Implement the discrete system obtained using block diagram..
