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.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
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.

2. Abrasive Machining
• Abrasive machining utilizes hard non-metallic
particles to finish the metallic workpieces in
order to improve surface finish and reduce the
surface roughness.
• Abrasive particles are usually bonded together
on the wheels, stones, sheets or in fluids or in
loose form.
5. The most commonly used materials?
• Aluminium oxide or alumina, the most widely
used abrasive, generally used for ferrous
alloys, high tensile materials and wood. Cubic
boron nitride (CBN) Zirconia/Alumina alloys,
suited to carbon and stainless steels and
welds. Glass, usually used for pressure
blasting operations.
• Sand or Silica particles
• Silicon Carbide
9. Surface Grinding
• It is a widely used abrasive machining process
in which a spinning wheel covered in rough
particles (grinding wheel) cuts chips of
metallic or nonmetallic substance from a
workpiece, making a face of it flat or smooth.
11. Surface Grinding
• The machine consists of a table that traverses both
longitudinally and across the face of the wheel. The
longitudinal feed is usually powered by hydraulics,
as may the cross feed, however any mixture of
hand, electrical or hydraulic may be used depending
on the ultimate usage of the machine (i.e.,
production, workshop, cost). The grinding wheel
rotates in the spindle head and is also adjustable for
height, by any of the methods described previously.
Modern surface grinders are semi-automated,
depth of cut and spark-out may be preset as to the
number of passes and, once set up, the machining
process requires very little operator intervention.
12. Surface Grinding
• Depending on the workpiece material, the
work is generally held by the use of a
magnetic chuck. This may be either an
electromagnetic chuck, or a manually
operated, permanent magnet type chuck;
both types are shown in the first image.
14. Cylindrical Grinding Machine
• Cylindrical grinding is defined as having four
essential actions:
• The work (object) must be constantly rotating
• The grinding wheel must be constantly rotating
• The grinding wheel is fed towards and away from
the work
• Either the work or the grinding wheel is
transversed with respect to the other.
