IRJET- An Experimental Study on High Strength Self-Compaction Concrete with Partial Replacement of Fly Ash as Cement and Copper Slag as Coarse Aggregate
This study experimentally investigates high-strength self-compacting concrete with partial replacements of fly ash for cement and copper slag for fine aggregate. Fly ash was replaced at levels of 5-25% by weight of cement, and copper slag was replaced at levels of 10-50% by weight of fine aggregate. The compressive, tensile, and flexural strengths of the concrete mixtures were tested at 7 and 28 days. Results showed that replacing cement with 15% fly ash and fine aggregate with 30% copper slag produced concrete with the highest strengths. The fresh concrete properties were also evaluated and found to meet the requirements for self-compacting concrete. Thus, the partial replacements of fly ash and copper slag can produce high-strength

Effect of thermal barrier coating for the improvement of si engine performanc...eSAT Journals
Abstract As per the second law of thermodynamics the efficiency of the engine depends upon the extraction of work against the heat supplied. Minimisation of heat rejection leads to increase the work. Heat rejection takes place through the engine piston, valves and cylinder heads to the surroundings. The aim of the study is to minimise this heat rejection to the surroundings. Heat transfer through the engine parts is minimised by applying the thermal barrier coating materials on the top surface of the engine piston, cylinder heads and valves. In this study an attempt is made to reduce the intensity of thermal and structural stresses by using a layer of the ceramic material, like Yttria stabilized zirconia (YSZ) which has low thermal conductivity, high thermal resistance, chemical inertness, high resistance to erosion, corrosion and high strength was selected as a coating material for engine component. This study present the effect of coating on the piston and the performance of modified four stroke petrol engine and the emission characteristics of the exhaust gas. Key words: Yttrium – zirconium coating, Low heat rejection, Thermal barrier coatings, Engine performance and Emission characteristics

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.
