Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Part A
1. State the major functions performed by the presentation layer of the ISO
OSI model.
It is concerned with the syntax and semantics of the information exchanged
between two systems.
Major functions are 1)Translation 2)Encryption 3)Compression
2. A Sine wave has a frequency of 6 Hz. What is its period?
T=1/f. T=1/6 =0.1515 seconds.
3. Stop and Wait Method:
After transmitting one frame, the sender waits for an acknowledgment
before transmitting the next frame. If the acknowledgement does not arrive after a
certain period of time, the sender times out and retransmit the original frame.
4. Two types of data frames
FDDI is designed to handle two types of traffic:
– Synchronous frames that typically have tighter delay requirements (e.g.,
voice and video)
– Asynchronous frames have greater delay tolerances (e.g., data traffic)
5. What are the two types of implementation formats in virtual circuits?
Virtual circuit transmission is implemented in 2 formats.
DSAP SSAP Control Information
Switched virtual circuit
Permanent virtual circuit.
Switched virtual circuit format is comparable conceptually to dial-up line in
circuit switching. In this method, a virtual circuit is created whenever it is needed
and exits only for the duration of specific exchange.
Permanent virtual circuits are comparable to leased lines in circuit switching.
In this method, the same virtual circuit is provide provided between two uses on a
continuous basis. The circuit is dedicated to the specific uses.
