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.
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.

40. E-TRAN
E-TRAN, which is developed by ELECTRANIX
Corporation, is a tool that allows for an automated
conversion of a very large system into PSCAD
(EMTDC) models from load flow programs .
It directly translates PSS/E data files (.raw, .dyr,
and .seq) into PSCAD files (.psc and .pscx).
E-TRAN internally solves the steady state phasor
equations and uses this information to initialize
the system in PSCAD and make the system
suitable for stability simulation analysis.
41. E-TRAN
• E-TRAN allows for the system to be partially or fully converted (all its nodes)
into PSCAD.
• Make sure the parameters of the generator models in PSS/E are
reasonable, otherwise it will cause the numerical problems in the generator
transition process from voltages sources to machines in PSCAD.
• E-TRAN typically converts the load model in PSS/E to constant PQ models
in PSCAD, which will probably lead to instability after releasing the load in
PSCAD. If allowed, load can be changed to the constant impedance model
to make the system stable after releasing load.
• The .raw file needs to be solved before being converted to the PSCAD file.
• Typically, both the .raw and .dyr files are needed in translation. If there is
only a .raw file, the translation can be done. However, the PSCAD file
translated based on the .raw file only can not simulate dynamic processes.
