System of Limits, Fits, Tolerance and GaugingTushar Makvana
To satisfy the ever-increasing demand for accuracy, the parts have to be produced with a less dimensional variation.
Hence, the labour and machinery required to manufacture a part has become more expensive.
It is essential for the manufacturer to have an in-depth knowledge of the tolerances to manufacture parts economically but, at the same time, adhere to quality and reliability aspects.
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.

In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
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.

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. Hole based
Hole basis System
• In the hole basis system the hole is kept constant
and the shaft size is varied to give the various types
of fits
• in this system lower deviation of the hole is zero
i.e. the lower limit of the hole is the same as the basic
size.
• The upper limit of the hole and the two limit of
the size of the shaft are then varied to give the desired
type of fit
3. Shaft basis system
• In the shaft basis system the shaft is kept constant
and the sizes of the hole is varied to give the various
types of fits.
• The upper deviation of the shaft is zero i.e. the
upper limit of the shaft is the same as basic size and
the various types of fits are obtained by varying the
lower limit of shaft and both the limits of hole.
4.
5.
6. The hole basis system is commonly used because it is
more convenient to make correct holes of fixed sizes
Shaft basis system is used when the ground bars or
drawn bars are readily available.
7. Gauges
• Gauge is a tool or instrument used to measure or
compare a component
• Gauges are scaleless inspection tool at rigid
design, which are used to check the diameters of
manufactured parts.
• They are also used to check the form and relative
positions of the surfaces of parts.
• they are only used to determine Wheather the
inspected part has been made within the specified
limits
8. Gauges differ from other measuring instruments
because
• No adjustment is required in their use
• They are not general purpose instruments but are
specially made for specific purposes
• They quick results
9. Types of gauges
According to their type
(a) Standard gauges (b) Limit gauges
According to purposes
(a) Workshop gauge (b) Inspection gauges
(c) Reference or master gauges
According to form of the tested surface
(a) Plug gauge (b) Snap, Gap, Ring gauge
According to their design
(a) Single limit and double limit gauges
(b) Single ended and double ended gauges
(c) Fixed and adjustable gauges
10. Limit Gauges
Are widely used
The gauges has got two ends
One end with upper limits and the other end with lower
limits
GO and NO-GO gauges
GO end checks the Maximum Metal limit
NO-GO end checks the minimum Metal limits
11. Gauge Tolerance
• Gauges cannot be manufactured to exact sizes
• Closer the limits more expensive the gauges
• Some variations cannot be eliminated due to
imperfections in the process, skill of worker etc.
Some allowances must therefore be provided to gauge
maker. This is known as gauge makers tolerance or
Gauge tolerance
12. Presentation of gauge tolerance
Magnitude of the gauge tolerance is determined
Position the tolerance relative to the work limits so
that it does not cause the gauge to accept defective
work
unilateral system of tolerance is preferred
