IRJET- Experimental Investigation and Optimization of Wear Characteristics of Aluminium Metal Matrix Composite Reinforced with Sillimanite (Al2sio5) by using Taguchi Technique
This document experimentally investigates the wear characteristics of an aluminium metal matrix composite reinforced with sillimanite particles. Pins made of aluminium LM25 alloy with 3%, 6%, and 9% sillimanite additions were tested using a pin-on-disc wear tester. Taguchi optimization techniques determined the optimum parameters for lowest wear rate were 9% sillimanite, 15N load, 100°C temperature, and 3.5 m/s sliding velocity. Analysis of variance found applied load and reinforcement percentage most influenced wear, contributing 33.63% and 44.92% respectively. A regression model was developed to predict wear rate based on the test parameters.

Metal matrix composites (MMCs) have a potential for enhanced wear conflict in
excess of the unreinforced aluminum alloy and are the most capable in achieving
enhanced mechanical properties. In the present investigation, composites of Aluminum
6061(Al6061) matrix material is reinforced with micron size Silicon carbide (μSiC)
reinforcement with 5, 10 and 15 weight percentages (wt.%) and nano size SiC (nSiC)
with 0.5, 1.0 and 1.5 wt.% are fabricated by stir casting technique. The stir casted
composites are further heat treated and the specimens are prepared as per ASTM
standards to conduct hardness and wear tests. The fabricated and heat treated nano
composites showed enhancement in hardness and wear resistance more than the micro
composites. The microstructure of the worn out specimen are examined by scanning
electron microscope. Taking into contemplation all the factors, it can be concluded that
aluminum based composite with 1.0% by weight nano SiC reinforcement acquire
superior wear resistance properties as compared to micro SiC reinforced aluminum
metal matrix composites.

Optimization of process parameter for stir casted aluminium metal matrix comp...eSAT Journals
Abstract From the past few years, materials research and development has shifted from monolithic to composite materials, adjusting to the need for reduced weight, low cost, quality, and high performance of the composites. Aluminium metal matrix composite used in areas of aerospace and automotive industries include high performance, economic and environmental benefits. The aim involved in designing the metal matrix composite is to combine the desirable attributes of metals and ceramics. The present investigation has been done to study the effect of different input process parameters namely particle size of alumina, wt. % of alumina and stirring time on the hardness, impact strength and tensile strength. Three parameter i.e. particle sizes of alumina (75, 105 and 150 micron), wt. % of reinforcement (3%, 6% and 9%), stirring time (15, 20 and 25 minute) was used to fabricate different sample of AMMCs by using stir casting technique. Each parameter has three different levels. L9 orthogonal array table used to made different specimen. The effect of these input process parameter on the output response have been analyzed using analysis of variance (ANOVA). The contribution of each process parameters on the hardness, impact strength and tensile strength was analyzed by using ANOVA. The results have shown that the wt. % of alumina, stirring time and the particle size of alumina have a significant effect on the hardness, impact strength and tensile strength.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
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.
