Explanation of Solution
Five keys for successful development projects:
The five keys for successful development projects are:
- Create a work-breakdown structure: One of the best approaches and strategy for SDLC (Software Development Life Cycle) projects is to divide and conquer. To simply large projects, project teams create a Work-Breakdown Structure (WBS) and divide into different goals.
- Estimating the time and cost: In order to develop successful development projects, one need to estimate the time and cost need to finish the project and organisations can use projects similar to this project for planning which would produce quality schedule estimates.
- Create a project plan: No great thing was ever achieved without planning. In order to build successful development projects, one needs to plan the project in advance so that the process of creating the project is smooth.
- A project plan is a list of Work- breakdown structures and the display is called a Gantt chart which shows tasks, dates and dependencies.
- Adjusting the plan by accessing trade-offs: In order to make a successful development project one needs to adjust the project plan by accessing trade-offs.
It can be done by balancing three factors: requirements, costs and time.
- Managing development changes: In order to make a successful developmental project one needs to manage the development changes by considering the coordination, diseconomies of scale, configuration control and unexpected changes.
Purpose of a Work-Breakdown Structure:
The actual purpose of a work breakdown structure is to reduce a large project and a complicated activity into a collection of tasks which can be divided into various teams.
A project plan is a list of Work- breakdown structures and the display is called a Gantt chart which shows tasks, dates and dependencies.
Here tasks must be measurable and independent with clearly defined limits that organizes the team’s work into manageable sections.
Difficulties of development estimation:
Some of the difficulties of development estimation are:
- Determine the duration of the project.
- Determine the labour requirements for many development tasks.
Three ways of addressing difficulties of development estimation:
The three ways of addressing difficulties of development estimation are:
- Avoid scheduling problems all together by licensing procedures that include both business process and
Information Systems. - In order to approach this challenge, organizations can never develop systems and software in-house.
- If packages are not available companies can admit the impossibility of scheduling a date for completing the entire project and look for the best result.
- One of the ways to address the difficulties is to attempt the schedule the development project in spite of all the difficulties.
Explain the elements in the Gantt chart:
The Gantt chart consists of three elements: tasks, dates and dependencies...

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));
