Problem Description:
Some highly confidential documents need to be kept in a super secured vault.
The vault has 5 steps of security checkpoints without any human security personnel. Only an
authorized person gets 5 different passwords to open and close 5 different security gates. Each
password is effective to open and close the very same gate once.
You have to enter 5 different authorized passwords to open 5 different gates. You have to keep track
of which password was used to open one gate so that you can close the gate with the same password
after finishing your job in the vault. You will finish your job in the vault and lock the series of gates
using the correct sequence (which one you used to enter) of passwords. The passwords will be of
string type.
Question 1: Which data structure would you choose to keep track of the sequence of passwords to
access the vault?
Answer:
Question 2: Write the Pseudocode of the insertion operation of this data structure.

PROJECT TITLE: IMPLEMENTATION OF DESIGN FOR RADIO FREQUENCY (RF) TECHNOLOGY BASED SPEED CONTROL SYSTEM FOR VEHICLES
PROJECT DESCRIPTION: Road safety at important places like schools, hill areas, highways, and expressways is very important. Roads should be designed for the safety of all road users, i.e., ensuring adequate facilities for pedestrians, cyclists, and motorcyclists. Measures such as footpaths, cycling lanes, safe crossing points, and traffic calming measures are critical to reducing the risk of injury among these road users. In this project, a speed control system for vehicles is proposed in which a microcontroller based system with RF based communication that is simple, low cost, and a durable project for safety of drivers as well as the public.

In some older homes that do not have a central heating and air conditioning system, smaller air conditioning units made to fit inside of a window and cool a single room are used as an alternative way to cool the home.
Depending on the size of the room and the amount of shade that the room has, different sizes of air conditioning units must be used in order to be able to properly cool the room. The unit of measure for the amount of cooling that an air conditioner unit can provide is the BTU (British Thermal Unit) per hour.
Code a program that will calculate the correct size of air conditioner for a specific room size using the instructions below.
Step 1:
Ask the user to enter the length of their room (in feet).
Step 2:
Ask the user to enter the width of their room (in feet).
Step 3:
Calculate the area (in square feet) of the room by multiplying the length and the width of the room.
For example, if a room is 20 feet wide by 24 feet long, then its area is 20 * 24 = 480 square feet

- Video-Rental LTD is a small video rental store. The store lends videos to customers for a fee, and purchases its videos from a local supplier. A customer wishing to borrow a video provides the empty box of the video they desire, their membership card, and payment – payment is always with the credit card used to open the customer account. The customer then returns the video to the store after watching it. If a loaned video is overdue by a day the customer's credit card is charged, and a reminder letter is sent to them. Each day after that a further card is made, and each week a reminder letter is sent. This continues until either the customer returns the video, or the charges are equal to the cost of replacing the video.

The gate can be opened either manually (by pushing the “OPEN” button) or when a sensor detects that a car is at gate. After the gate fully opens, it can be closed by pushing the “CLOSE” button. It can be also closed after 10 seconds from being fully opened, but only if there is no car at gate.Create state transition table for the above case based on the image given.arrow_forward

Every customer must have a AVS customer card in order to rent a video, or he need to apply for one. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that they do not have any overdue videos. If so, the overdue videos must be returned and an overdue fee paid before customer can rent more videos. Likewise, if the customer has returned overdue videos, but has not paid the overdue fee, the fee must be paid before new videos can be rented. Every morning, the store manager prints a report that lists overdue videos. If a video is two or more days overdue, the manager calls the customer to remind them to return the video. If a video is returned in damaged condition, the manager removes it from the video database and may sometimes charge the customer. Task 1: Behavioral communication diagram.

- Computer Science Internship training is one of the graduation requirements for undergraduate students in UTP. Students are usually posted to different companies, agencies, and organizations for the training. After the posting, the first activity that is conducted by students is to search for accommodation in proximity with the company to which they are posted. However, this task is not always easy as students may not be familiar with the company’s neighborhood. As a results, many websites are designed to recommend the best hotel/homestay for students using a recommender system. This system uses hotel rating to predict which hotel a user is most likely to choose from among all hotel/homestay. Nevertheless, in the case of students, rating alone is not enough for a suitable prediction, other important factors should also be considered. Assuming you are among the students who will be posted next semester for this training, build a system which will help you and your friends to book the…arrow_forwardVideo-Rental LTD case study Video-Rental LTD is a small video rental store.
