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.

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.
1. Network Topology
Computer network topology is the way various
components of a network (like nodes, links,
peripherals, etc) are arranged. Network
topologies define the layout, virtual shape or
structure of network, not only physically but
also logically. The way in which different
systems and nodes are connected and
communicate with each other is determined
by topology of the network.
2. Topology can be physical or logical
• Physical Topology is the physical layout of
nodes, workstations and cables in the
network.
• Logical topology is the way information flows
between different components.
3. Types of Physical Network Topologies
• Bus Topology
• Star Topology
• Ring Topology
• Mesh Topology
• Tree Topology
• Hybrid Topology
4. Bus Topology
• In the bus topology, the computers are
connected through a common communication
media. A special type of central wire is used as
communication media. This central wire is
called Bus. The computer are attached
through the bus the ends of the bus are closed
with the terminator .The terminators are used
to absorb signals.
5.
6. Advantages of Bus Topology
• Easy to install and configure
• Inexpensive
• Easily extended
7. Disadvantages of Bus Topology
• Performance decreases
• Weak signals
• Difficult troubleshooting
8. Star Topology
• The star topology uses a separate cable for
each work station as shown in fig.The cable
connects the work station to a central device
typically a HUB. The configuration provides a
more reliable network that is easily expended.
With star there is no central point of failure in
the cable .if there is a problem with the cable
only the station connected to that cable is a
effected .to add more work stations simply
connect another HUB
9.
10. Advantages of Star Topology
• Easily expended and modified
• Easy to troubleshoot
• Multiple cable types supported by hub
11. Disadvantages of Star Topology
• If hub fails then entire network will fail
• Require more cables
• May require a device to rebroadcast signals
across the network
12. Ring Topology
• Every computer is connected to the next computer in the
ring and each transmits what it receives from the previous
computer. The messages flow around the ring in one
direction.
Some ring network do ring token passing. A short message
called token (memory area)is passed around a ring until a
computer wishes to send information to other computers.
That computer modifies token, adds an electronic address
and data and send it around the ring. Each computer in
sequence receives the token and next computer until either
the electronic address matches the address of a computer
Or the token return to its origin .The receiving computer
returns a message to the sender indicating that message
has been received.
13.
14. Advantages
• It provides an orderly network in which every
device has access to the token and can
transmit.
• It performs well under a heavy load.
15. Disadvantages
• Failure of one computer can effect the whole
network .
• Difficult to troubleshoot.
• Change mode with adding or removing a
device effect the entire network.
16. Mesh Topology
• A mesh network or mesh topology uses
separate cable to connect each device to
every other device on the network, providing
a straight communication path. For sending
messages, check the cable connected into two
devices. A message is send directly from
sender to receiver because each one has
individual and separate connection.
20. Tree Topology
• The type of network topology in which a central 'root' node (the
top level of the hierarchy) is connected to one or more other nodes
that are one level lower in the hierarchy (i.e., the second level) with
a point-to-point link between each of the second level nodes and
the top level central 'root' node, while each of the second level
nodes that are connected to the top level central 'root' node will
also have one or more other nodes that are one level lower in the
hierarchy (i.e., the third level) connected to it, also with a point-to-
point link, the top level central 'root' node being the only node that
has no other node above it in the hierarchy (The hierarchy of the
tree is symmetrical.) Each node in the network having a specific
fixed number, of nodes connected to it at the next lower level in the
hierarchy, the number, being referred to as the 'branching factor' of
the hierarchical tree.
21.
22. Advantages
• It is scalable.Secondary nodes allow more
devices to be connected to a central node.
• Point to point connection of devices.
• Having different levels of the network makes it
more manageable hence easier fault
identification and isolation.
23. Disadvantages
• Maintenance of the network may be an issue
when the network spans a great area.
• Since it is a variation of bus topology, if the
backbone fails, the entire network is crippled.
24. Hybrid Topology
• Hybrid networks use a combination of any two or
more topologies in such a way that the resulting
network does not exhibit one of the standard
topologies (e.g., bus, star, ring, etc.). For example,
a tree network connected to a tree network is still
a tree network topology. A hybrid topology is
always produced when two different basic
network topologies are connected. Two common
examples for Hybrid network are: star ring
network and star bus network.
