Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid
Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of Piping Design (or Piping Engineering). Piping systems are documented in piping and instrumentation diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process.
"Piping" sometimes refers to Piping Design, the detailed specification of the physical piping layout within a process plant or commercial building. In earlier days, this was sometimes called Drafting, Technical drawing, Engineering Drawing, and Design but is today commonly performed by Designers who have learned to use automated Computer Aided Drawing / Computer Aided Design (CAD) software

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.

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.

3. What are basic functions of instruments?
Ans : To sense, transmit, indicate, read and control.
4. Why block valve is used at the root of an instrument like pressure
indicator?
Ans : They are needed to isolate gages for maintenance during plant
operation and during hydrostatic testing of piping system. They
are called root valve.
5. Where diaphragm assembly is used ?
Ans : For corrosive, abrasive, viscous fluids. Neutral fluid like glycol is
used on instrument side of diaphragm.
6. Where and why bleed valve is used in instruments ?
Ans : If the conveyed fluid is hazardous or under high pressure, a
branch fitted with a bleed valve is inserted between the gage and its
isolating valve, to relieve pressure and /or drain the liquid before
servicing the gage. It can also be used to sample or for adding a
comparison gage.
7. Why control valves are usually flanged?
Ans : For ease of installation and removal during maintenance.
8. Where ball control valve is used?
Ans : Suitable where nature of fluid is slurry form or handling two
phase flow having particle in suspension, for non-critical and critical
fluids having a fluid temperature to suit the soft seat material and
where relatively low pressure drop is required across control valve. They
have side mounted actuator.
9. Where butterfly control valve is used ?
Ans : Used for large size piping network handling clean fluid for low
pressure drop across control valve and soft seated control valve. Metal
seated valves used for higher temperatures.
10. How control valve block valves should be located ?
Ans : They should be as close to control valve as possible, considering
drain requirement and handwheel clearance. At least one of the block
valve should be placed in vertical so that spool can be removed allowing
the control valve to be removed.
