I. Design components of SLA 3d printer.
II. Assembly.
III. Finite Element Analysis - Using Ansys for structural
IV. Finite Element Analysis - CFD
When I searched for the recent technology and developments in SLA/ DLP printers, I found limited resources that speaks about the existing problems, but there is ample of resources that talk about the technology and its basics. Very limited open source material is available online related to this topics. A candidate without the firsthand experience of these printers will never be able to understand the limitations. Hence these efforts are made to make the problem statement more open source to the people who cannot actually have the privilege to experience such printers first hand. This paper talks about the normal problems one faces while operating this printer, cautions and maintenance aspects I hope all the information provided in this report shall and will be used for the development of existing technology.
This report discusses new advances in technologies like regenerative breaking, mass production that reduces cost, battery management system, and higher battery life and battery efficiency are the few of the techies that made electric cars a within the reach of the common man.

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.

RESULTS AND DISCUSSION
Most of the part modelling and assemblies were executed smoothly and completed successfully. However, I faced
problem in one of the assemblies. During the assembly of BLOWER.PRT with FRAME.PRT the constraints were applied
and the impeller was fully constrained with crankshaft. But while dragging the impeller blades, the assembly did not
rotate as required and all the other parts were stagnant.
After detailed analysis and by trial & error of all the assemblies involved, it was found that crankshaft was not passing
through the center of the impeller hole which was creating interference for the motion. The root cause for this
mismatch was because the holes on the frame where blower is mounted was not in the exact location as per
requirement which created offset in the axis of crankshaft and impeller hole.
The holes which were not in the correct locations were modified and the holes at the correct locations were created.
The blower assembly was then assembled on the frame by using the corrected holes as constrain so as to fully
constrain the assembly. By making the above changes, the piston reciprocated when the impeller blades were rotated.
This is the actual motion which was required

4.1. The parts were successfully modelled to the required dimensions and assembled using the right constraints.
4.2. The impeller rotates when the piston is moved in the vertical direction. Hence, it shows that the motion is being
successfully transmitted from the piston to the impeller.
4.3. The air circulator pulls the air into the impeller from the surroundings by suction generated due to centrifugal
force and is thrown out from the impeller housing nose with speed.
