Chapter 9, Problem 4E
Explanation of Solution
Designing an electronic monitoring plan in order to secure resources and information:
Electronic monitoring plan design
Electronic monitoring:
Electronic monitoring system is important in an organization or any other places. CCTV is one of the monitoring systems, which are placed in a corner of a room. It should be constantly monitored and checked.
Burglar alarm:
It is the most commonly used alarm system. It is used to find out interferences into unauthorized places and it alerts the remote security agency. They should be checked periodically.
Sensors of burglar alarm:
Burglar alarm contains various sensors like,
Motion detectors:
- Burglar alarm with motion detector can be used in corridors, and in the server room to detect motion of trespassers or other unauthorized people.
- They are either active or inactive. They emit energy beams like infrared or sound waves or other radiation. If the energy is disturbed, the alarm gets activated.
Thermal detectors:
- Burglar alarm with thermal detector can be used in server room or in the work place.
- The thermal detectors are used to detect heat. They contain heat sensors that act in two ways.
- In the first way, the sensor works when the temperature in some areas reaches a predetermined level that is, 135 to 165 degrees Fahrenheit.
- In the other way, the sensor finds the rate of rise in temperature. Here, the sensors find the rapid increase in temperature within less amount of time.
Glass breakage detectors:
- Burglar alarm with glass breakage sensor can be used near doors or windows.
- It detects of the pane of glass is broken. They contains microphone through which they detect the breakage of glass...

Why is Linux popular? What would make someone choose a Linux OS over others? What makes a server? How is a server different from a workstation? What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
Objective you will:
1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five)
2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector.
3. Compare the performance of TreeSort with C++'s std::sort on large datasets.
Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST):
1. Insert all elements into a BST (logically sorting them).
2. Traverse the BST in-order to extract elements in sorted order.
3. Store the sorted elements in a vector.

I need help fixing the minor issue where the text isn't in the proper place, and to ensure that the frequency cutoff is at the right place.
My code:
% Define frequency range for the plot
f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz
w = 2 * pi * f; % Angular frequency
% Parameters for the filters - let's adjust these to get more reasonable cutoffs
R = 1e3; % Resistance in ohms (1 kΩ)
C = 1e-6; % Capacitance in farads (1 μF)
% For bandpass, we need appropriate L value for desired cutoffs
L = 0.1; % Inductance in henries - adjusted for better bandpass response
% Calculate cutoff frequencies first to verify they're in desired range
f_cutoff_RC = 1 / (2 * pi * R * C);
f_resonance = 1 / (2 * pi * sqrt(L * C));
Q_factor = (1/R) * sqrt(L/C);
f_lower_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) + 1/(2*Q_factor));
f_upper_cutoff = f_resonance / (sqrt(1 + 1/(4*Q_factor^2)) - 1/(2*Q_factor));
