Design of Waste Water Treatment Plant for treating the Effluent generated fro...Rita EL Khoury
One of the major issues of environmental pollution is the direct discharge of contaminated water into sewage system. In fact, operating the autoclave reactor unit in a medical waste treatment facility generates waste water that might cause environmental hazards if it doesn’t undergo an appropriate treatment process. The effluents generated from the autoclave drainage and from waste bins washing, being exposed to infectious medical waste, contain pollutants such as bleaches, particulates, detergents, and pathogenic microorganisms.
Medical waste must be decontaminated and treated without generating a secondary pollution. For this reason, a treatment process consisting of the following unit operations: aerated septic tank, sand filter, softener, cartridge and UV Sterilizer is designed in order to treat these effluents and thus re-use the obtained clean water for bins washing, as cooling water or if possible as boiler feed water.
This presentation provides with information regarding the processes , methods , applications of Water Treatment and simple design of water treatment filters. It incorporates chlorination, aeration, and other miscellaneous methods for water treatment

Rapid sand filtration is a technique common in developed countries for treating large quantities of drinking water. It is a relatively sophisticated process usually requiring power-operated pumps for backwashing or cleaning the filter bed, and flow control of the filter outlet. A continuously operating filter will usually require backwashing about every two days when raw water of relatively low turbidity is used.
Raw water should be treated to make it potable/fit for drinking. So a line of treatments should be followed to treat the water. After Coagulation and sedimentation the process of filtration and disinfection are followed.
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.

It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
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.

2. OSMOSIS
• A process by which molecules of a
solvent tend to pass through a
semipermeable membrane from a less
concentrated solution into a more
concentrated one.
REVERSE OSMOSIS
• A Process by which solvent passes
through a porous membrane in the
direction opposite to that of natural
osmosis when subjected to a
hydrostatic pressure greater than
osmotic pressure.
3. SEMI PERMEABLE MEMBRANE
• It is a membrane that may or may not
allow particles to pass through
it.permeable is defined as membrane
that can be crossed by particles,ions
or water.semi permeable means that
some particles,ions or water can cross
the membrane.

6. DESIGN PROCEDURE OF RO PLANT
1. Ground water or Raw water analysis:
In this process the ground water is analysed to find the Total Dissolved
Solids(TDS).Membrane is selected based upon the TDS value obtained in the raw
water.
TDS value can be majorly calculated by using these two methods:
• Using an electrical conductivity meter
• Using filter paper and a scale
7. SAND FILTERS
• At first ground water is collected and
passed through sand filters,the filter
media is supported on gravel bed that
consists of multiple layers of graded
quartz sand,fine sand,super fine white
sand and pebbles of progressively
large size.
• The filter will effectively remove up
to 30 – 50 micron of the suspended
solids to less then 5 ppm.

18. contd...
• After passing through membranes the permeate water comes out from the permeate
inlet with a certain pressure and reject water is drained off.
advantages:
• RO systems remove dissolved minerals and other contaminants that may cause
water to smell unpleasant, and look odd.
• Reverse osmosis purification systems are best for home filtration systems
because they are small in size.
• Water treated by RO water filters is ideal for people suffering from heart
disease, because they eliminate almost all salt and remove 99% of bacteria.
disadvantages:
• Generally pH value of permeate water is less i;e between below 6.5 which is
acidic.
• And the rejected water from RO is more and also useless and causes ground
water pollution
