PEX Piping is amongst the best innovative material, is being utilized in our prefab modular homes and buildings for water distribution systems. Water leaks are most common problem in households and it can be avoided with PEX-AL-PEX piping and fittings as the system have less joints plus takes less time to complete the job and has become favorite among leading plumbers.

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.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
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.

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.

Selection of Pipes for Water Supply in Residences
Earlier only GI pipe was available for water supply but now new piping materials are being introduced in
the market making it difficult to chose the best to use in your dream house .
Properties of some of the more common pipes used these days like, CPVC, Composite (PE/Al/PE),
PEX and Stainless Steel have been compared; cost has been analysed based on the length of pipes
and fittings like, bends, tees etc. used in a typical house (excluding CP fittings like angle or concealed
valves, faucets etc. which can vary according to personal preference). Comparison table is attached.
Major observations are summarised below:
1. Water supply pipe like drainage pipes and electrical wires are the arteries of any building supplying
services to a building. These get embedded in the building behind wall and floor finishes and are
hidden from view, but they are expensive and troublesome to replace, therefore reasonable thought
should go in selecting these vital items for your house. Even though the cost of water supply pipes
may be less than 0.5% of the total cost of the house they deserve serious consideration.
2. CPVC has the lowest cost, is easy and quick to install. Pipes which are exposed to sunlight can age
and become brittle. CPVC has been used for quite some time and can be a good choice where
there is a constraint for budget.
3. Composite pipes constructed with a Aluminium layer sandwiched between two PE(Polyethylene) or
PEX(Cross Linked Polyethylene) layers combine the advantages of both metal as well as plastics. It
has thermal expansion close to metal pipes; can be easily bent. making it easy to lay. Recently one
manufacturer has introduced pre-insulated composite pipes. This pipe, though about 4 -5 times
more expensive as compared to CPVC pipes, is an excellent choice for water supply for external as
well as internal use.
4. PEX tubing is the latest piping on the market. It has the unique advantage that it can reduce all
fittings behind the wall to zero and if installed properly can be pulled out like a wire for replacement.
However it cannot be used for external application like carrying water from the Overhead Water
Tank to the toilet. PEX is about 25% to 50% more expensive than Composite pipes.
5. Stainless Steel is an excellent pipe material but seems an overkill in residences.
6. Proper design and workmanship is the key, manufacturers instructions should be strictly followed in
laying and jointing methods for all pipes to perform well in the long run.
The above is based on information from various sources and is being shared in good faith to assist people in
taking an informed decision. For any feedback please contact sudhirgupts@me.com.

Comparison of Water Supply Pipes

3.1.2.3 Multilayer pipes
Multilayer composite tubes consist of two polymer layers, one of them inside the pipe,
the other outside. These layers are made of polyethylene with a high heat resistance.
The two layers are separated by a central polymer layer made of aluminum. This gives
greater strength pipe and provides an oxygen barrier. Aluminum layer on the outside
and the inside is covered with adhesive layers.
FIGURE 9. Principal scheme of the multilayer pipe
Multilayer pipe produced using TIG-welding (Tungsten Inert Gas). In TIG welding
method uses inert argon gas. With it welded aluminum layer. Multilayer pipe can be
used for hot and cold water and under floor heating.
Multilayer pipes can operate at temperatures ranging from 0 °C to 70 °C. Pipes can
withstand a maximum pressure of 10 bars. For 100 hours for all the life cycle of the
pipe it is capable of operating at a temperature of 95 °C /14./
Multilayer pipes have good UV protection. This allows you to install from the open
way. As with PEX pipe must adhere to the same manufacturer. You have to buy the
pipe, fittings, and tools with a single manufacturer. This is a pretty big drawback.
As well as PEX tubing and copper pipes, multilayer pipes can be in rolls or individual
pieces of straight pipes. This gives us a choice. For laying long lines would be better to
use pipes in the coil to reduce the number of connecting nodes. Coil length may reach
500 meters /14./
