This document discusses metal matrix composites (MMCs). MMCs consist of a metal matrix reinforced with materials like ceramics or other metals to improve upon the properties of the base metal. Some benefits of MMCs include high strength and stiffness with low weight, improved fatigue and toughness properties compared to metals, and no corrosion issues. MMCs can be made with a variety of matrix and reinforcement combinations and fabricated using common metalworking techniques.
Metal matrix composites (MMCs) possess significantly improved properties including highspecific strength; specific modulus, damping capacity and good wear resistance compared to unreinforced alloys. There has been an increasing interest in composites containing low density and low cost reinforcements. Among various discontinuous dispersoids used, fly ash is one of the most inexpensive and low density reinforcement available in large quantities as solid waste by-product during combustion of coal in thermal power plants. Hence, composites with fly ash as reinforcement are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications.

A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal necessarily, the other material may be a different metal or another material, such as a ceramic or organic compound. When at least three materials are present, it is called a hybrid composite.
Composite Materials are widely used in day today life and as well as in automotive and aerospace industry which are monolithic composites.but most of the monolithic composites are not able to achieve required mechanical properties,so to achieve those mechanical properties Metal Matrix composites widely used in different sectors.some of Compiled information on MMC are presented in this presentation.

Composites are made by combination of two or more natural or artificial materials to maximize their useful properties and minimize their weaknesses.
Example: The oldest and best-known composites,
Natural: Wood combination of cellulose fibre provides strength and lignin is the "glue" that bonds and stabilizes. Bamboo is a very efficient wood composite structure.

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.
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.

The family offers a choice of engines
2. A materials system composed of two or more
physically distinct phases whose combination
produces aggregate properties that are
different from those of its constituents
Examples:
◦ Cemented carbides (WC with Co binder)
◦ Plastic molding compounds containing fillers
◦ Rubber mixed with carbon black
◦ Wood (a natural composite as distinguished from a
synthesized composite)
3. Composites can be very strong and stiff, yet very
light in weight, so ratios of strength-to-weight
and stiffness-to-weight are several times greater
than steel or aluminum
Fatigue properties are generally better than for
common engineering metalscommon engineering metals
Toughness is often greater too
Composites can be designed that do not corrode
like steel
Possible to achieve combinations of properties
not attainable with metals, ceramics, or polymers
alone
4. Disadvantages
Many of the polymer-based composites are
subject to attack by chemicals or solvents,
just as the polymers themselves are
susceptible to attack
Composite materials are generally expensiveComposite materials are generally expensive
Manufacturing methods for shaping
composite materials are often slow and costly
8. Protect phases from environment
Transfer Stresses to phases
Holds the imbedded phase in place,
usually enclosing and often concealing it
When a load is applied, the matrix sharesWhen a load is applied, the matrix shares
the load with the secondary phase, in
some cases deforming so that the stress is
essentially born by the reinforcing agent

prevent a chemical reaction with the matrix.
19. The matrix is the monolithic material into which
the reinforcement is embedded, and is
completely continuous.
This means that there is a path through theThis means that there is a path through the
matrix to any point in the material, unlike two
materials sandwiched together.
The matrix is usually a lighter metal such as
aluminum, magnesium, or titanium, and provides
a compliant support for the reinforcement.
20. The reinforcement material is embedded into
