What are the methodology and framework that can be use in seismic evaluation using modal pushover analysis?

What is the assumption regarding the cost of the latest units purchased in LIFO methodology?

In a power system using both Hydro and thermal generation, the proportion of hydro generation can be increased by.

a.  Increasing the price of water

b.  Reducing the price of water

c.  Increasing the field current of the Hydro generators

d.  Used salt water

A bandpass filter passes signals with frequencies that are within a certain range.In this filter the ratio of the magnitudes of the voltages is given by:
RV=V0/Vi=wRC/sqrt(1-w^2LC)^2+(wRC)^2 where w is the frequency of the input signal.Given R=1000ohm,L=11mH and C=8µF,determine the frequency range that corresponds to RV>=0.87.
Using MATLAB:
a) First plot the graph
b)Use matlab to construct a script for the Bisection method and Newton's method to find one of the possible roots.
