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.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
3. Maintenance
Maintenance is work that is carried out to preserve an asset (such as a
roof or a heating boiler), in order to enable its continued use and
function, above a minimum acceptable level of performance, over its
design service life, without unforeseen renewal or major repair
activities
4. Reasons for Maintenance
Maintenance serves to protect the owners’ real estate investment in a number of ways
Physical Integrity
To keep the assets in good working order so as to minimize disruptions and downtimes.
Risk Management
To keep the assets in a state of good repair for the owners’ health and safety.
Aesthetic Preservation
To keep the assets from deteriorating in appearance and becoming unsightly.
Responsible Stewardship
To ensure that the assets achieve their full potential service life.
5. Duty of Care
To satisfy a legislated duty that is owed to owners, occupants and guest on the property.
Duty to Mitigate
To prevent unnecessary damage to assets that may result in their premature failure.
6. Types Of Maintenance
Breakdown maintenance
Preventive maintenance
1. Periodic maintenance ( Time based maintenance - TBM)
2. Predictive maintenance
I. Condition Monitoring
Corrective maintenance
7. Break Down Maintenance
It means that people waits until equipment fails and repair it. Such a thing could be used when
the equipment failure does not significantly affect the operation or production or generate any
significant loss other than repair cost.
Preventive maintenance
It is a daily maintenance ( cleaning, inspection, oiling and re-tightening ), design to retain the
healthy condition of equipment and prevent failure through the prevention of
deterioration, periodic inspection or equipment condition diagnosis, to measure deterioration. It
is further divided into periodic maintenance and predictive maintenance. Just like human life is
extended by preventive medicine, the equipment service life can be prolonged by doing
preventive maintenance.
8. Periodic maintenance
Time based maintenance consists of periodically inspecting, servicing and cleaning equipment
and replacing parts to prevent sudden failure and process problems
Predictive maintenance
This is a method in which the service life of important part is predicted based on inspection or
diagnosis, in order to use the parts to the limit of their service life. Compared to periodic
maintenance, predictive maintenance is condition based maintenance. It manages trend
values, by measuring and analysing data about deterioration.
9. Condition Monitoring
Condition monitoring is the process of determining the condition of machinery while in
operation.
The key to a successful condition monitoring programme includes:
1. Knowing what to listen for
2. How to interpret it
3. When to put this knowledge to use
Successfully using this programme enables the repair of problem components prior to
failure.
Condition monitoring not only helps plant personnel reduce the possibility of catastrophic
failure, but also allows them to order parts in advance, schedule manpower, and plan other
repairs during the downtime.
10. Corrective maintenance
It improves equipment and its components so that preventive maintenance can be carried out
reliably. Equipment with design weakness must be redesigned to improve reliability or
improving maintainability
11. Advantages And Disadvantages
Break Down Maintenance
Advantages Disadvantages
Lower start up cost Unpredictability
Limited personnel requirement Equipment not maximised
Reduced maintenance costs Indirect costs
Potentially increased margins
12. Preventive Maintenance
Advantages Disadvantages
Over all very cost effective Catastrophic failure still a risk
Flexibility can allow for adjustment of
schedule to accommodate other work
Labour Intensive
Increased equipment life Performance of maintenance based on
schedule not required
Saved energy cost resulting from
equipment running from pick efficiency
Risk of damage when conducting
unneeded maintenance
Reduced equipment or process failure Saving not readily visible without a base
line
Over all saving between 12% to 18%
13. Predictive Maintenance
Advantages Disadvantages
Increased component operational
life/availability
Increased investment of diagnostic
equipment
Allows for pre-emptive corrective action Increased staff training for analysing data
Decreased part and labour cost Saving not readily visible without a
baseline/history
Improved safety and environment
Energy savings
Over all saving between 8% to 12% over
preventive maintenance
14. Condition Monitoring
Advantages Disadvantages
Extend bearing service life Monitoring equipment costs
Maximise machine productivity Operational costs (running the program)
Minimise unscheduled downtime Skilled personnel needed
Safely extend overhaul intervals Strong management commitment
needed.
Improve repair time A significant run-in time to collect
machine histories and trends is usually
needed.
Increased machine life
Improve product quality
Reduce product cost
Enhance product safety
15. Corrective Maintenance
Advantages Disadvantages
Lower short-term costs Increased long-term costs due to
unplanned equipment downtime.
Requires less staff since less work is
being done
Possible secondary equipment or process
damage.
Prone to neglect of assets
16. Case Study
Aircraft Maintenance
Aircraft maintenance is the overhaul, repair, inspection or modification of an aircraft and
aircraft components
Airlines authorities casually refer to the detailed inspections as "checks―
Different Types of checks
1. A check
2. B check
3. C check
4. D check
Among all the checks A and B checks are lighter checks, while C and D are considered
heavier checks.
17. A Check
This is performed approximately every 500 - 800 flight hours or 200 - 400 cycles. It needs
about 20 - 50 man-hours and is usually performed overnight at an airport gate or hangar. The
actual occurrence of this check varies by aircraft type, the cycle count (take off and landing is
considered an aircraft "cycle"), or the number of hours flown since the last check.
B Check
This is performed approximately every 4–6 months. It needs about 150 man-hours and is
usually performed within 1–3 days at an airport hangar. A similar occurrence schedule applies
to the B check as to the A check. B checks may be incorporated into successive A checks
18. C Check
This is performed approximately every 20–24 months or a specific amount of actual flight
hours (FH) as defined by the manufacturer. This maintenance check is much more extensive
than a B Check, requiring a large majority of the aircraft's components to be inspected. This
check puts the aircraft out of service and until it is completed, the aircraft must not leave the
maintenance site. It also requires more space than A and B Checks—usually a hangar at a
maintenance base. The time needed to complete such a check is generally 1–2 weeks and the
effort involved can require up to 6000 man-hours
D Check
This is by far the most comprehensive and demanding check for an airplane. It is also known
as a Heavy Maintenance Visit (HMV). This check occurs approximately every 5 years. It is a
check that, more or less, takes the entire airplane apart for inspection and overhaul. Also, if
required, the paint may need to be completely removed for further inspection on the fuselage
metal skin. Such a check can usually demand up to 50,000 man-hours and it can generally take
up to 2 months to complete, depending on the aircraft and the number of technicians involved.
It also requires the most space of all maintenance checks, and as such must be performed at a
suitable maintenance base. Given the elevated requirements of this check and the tremendous
effort involved in it, it is also by far the most expensive maintenance check of all, with total
costs for a single visit ending up well within the million-dollar range.
19. NDT In Aircraft Maintenance
During aircraft maintenance 'NONDESTRUCTIVE TESTING' (NDT) is the most
economical way of performing inspection and this is the only way of discovering defects.
In order to maintain the aircraft defects free and ensure a high degree of quality &
reliability and as a part of inspection programme, usually following NDT methods are
applied;
1) Liquid penetrant
2) Magnetic particle
3) Eddy current
4) Ultrasonic
5) Radiography (x-ray/gamma ray)
6) Visual/Optical
7) Sonic/Resonance
8) Infrared Thermography.
