Abstract Natural fiber composites are nowadays being used in various engineering applications to increase the strength and to optimise the weight and the cost of the product. Various natural fibres such as coir, sisal, jute, coir and banana are used as reinforcement materials. In this paper both treated and untreated banana fiber are taken for the development of the hybrid composite material. The untreated banana fiber is treated by sodium hydroxide to increase the wettability. The untreated banana fiber and sodium hydroxide treated banana fiber are used as reinforcing material for both Epoxy resin matrix and Vinyl ester resin matrix. Coconut shell powder is used along with both untreated and treated banana fiber as a reinforcing material. In this process the banana fiber is treated with 5% of sodium hydroxide for one hour and the specimen is fabricated by hand moulding process. The mould used for fabricating the hybrid composite material is made up of aluminium with a debonding agent applied on the inner side. The banana fiber content is kept constant to 30% of weight fraction of entire composite material. The variation in mechanical properties are studied and analyzed. Here, the tensile strength has calculated by universal testing machine, impact strength has calculated by pendulum impact tester and flexural strength has calculated by universal testing machine with flexural test arrangement of the specimen. Then the treated and untreated specimens are analyzed and compared through Scanning Electron Microscope to study about its adhesion between fiber and resin matrix and surface morphology.

An investigation was made to evaluate the effect of the incorporation of bio-based jatropha oil cake (JOC), Titanium dioxide (TiO2) and Clay on the erosive wear behavior of Basalt-epoxy (BE) hybrid composites. A Vacuum-Assisted Resin Infusion (VARI) technique was employed to obtain a filled and unfilled B-E composites. The effect of different impact velocities (20 and 40 m/s) and angle of impingement from 300 to 900 on the performance of the wear resistance of the composites were measured. The results of erosive wear losses, angle of impingement, and impact velocity and erosion rate of 3% of TiO2 and JOC filled and unfilled B-E composites are analyzed and discussed. The worn surface features of unfilled and filled B-E composites were examined using Scanning Electron Microscopy (SEM).
One of the trends of research in sustainability is focused on the development of coir fibre reinforced epoxy
composites. Many researchers have been investigated the effects of coir fibre fibrillation
on the tensile strength. The sorting treatment to this coir based on the uniformity of
diameters and the fiber was cut between 10-20 mm. The preliminary treatment was
done by cooking the coir in 5% NaOH solution in 80∘C for approximately 10-15 minutes.
This process then can be addressed to the fibrillation process. This process was carried
out by using a high-speed blender at 5 and 10 minutes, respectively. After that, the
composite was formed by hand lay-up, with the composition coir volume fraction and
matrix of 20:80. The results show that the treated Coir can increase the composite
tensile strength upto 14%. The highest tensile Strength was obtained for EAC 10-10
composite on vial volume of 30% fiber and 70% epoxy i.e.53.70 MPa.

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.
