In computer science, a stream is a sequence of data elements made available over time. A stream can be thought of as items on a conveyor belt being processed one at a time rather than in large batches.
Streams are processed differently from batch data :
*Normal functions cannot operate on streams as a whole, as they have potentially unlimited data, and formally
*Streams are codata (potentially unlimited), not data (which is finite).

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.

2. . Serialization in Java : Java Serialization is the mechanism in
which the state of an object is converted to a byte stream so
that the byte stream can be reverted back into the copy of the
object written into a file or stored into a database. It includes
information about object’s type and types of data stored in the
object.
Once the object is serialized into written into a file, it can be
read from the file and deserialized which means that the type of
information and bytes that represent the object can be utilized
to create object in the memory

Let’s understand streams in computer systems before proceeding
further. A stream is simply a sequence of data elements. Data in
the form of streams is generated from a source and consumed at
a destination.
Different data streams in the computer systems are:
1. Byte Stream – It is a low level I/O operation and does not have
any encoding scheme. The Java program should have a buffered
approach for I/O operations to process Byte Stream.
4. Copyright @ 2015 Learntek. All Rights Reserved. 4
2. Data Stream – Data Stream allows to read-write primitive
data types and used to perform binary I/O operations on
primitive data types. I/O operations can be performed for byte,
char, boolean, short, int, long, float, double and strings
efficiently and conveniently.
3. Character Stream – The character stream can easily
translate to and from local character set unlike byte stream. It
has a proper encoding scheme such as UNICODE, ASCII and
is composed of streams of characters. In Java UNICODE
system is followed to store characters as character stream.
5. Copyright @ 2015 Learntek. All Rights Reserved. 5
4. Object Stream – Object stream can covert the state of an
object into a byte stream so that it can be stored into
a database, file or transported to any location (Serialization)
and used at a later point of time for retrieving the stored
values and restoring the old state of the object.
The process of serialization is instance independent which
means an object can be serialized on one platform and
deserialized on an entirely different platform. To make an
object serializable we use java.io.Serializable interface.
6. Copyright @ 2015 Learntek. All Rights Reserved. 6
Both the classes Object Input Stream and Object Output
Stream are high-level streams and extend java.io.InputStream
and java.io.OutputStream.
The ObjectOutputStream has many write methods for writing
different data types. One of the popular write method in
ObjectOutputStream is:
This method serializes an object and converts it into stream of
bytes and sends it to output stream. The popular method to
read an object in ObjectInputStream is:
7. Copyright @ 2015 Learntek. All Rights Reserved. 7
This method reads the stream of bytes and converts it
back to an object which is called deserialization.
Java Serialization API contains methods for serialization
and deserialization. A class must implement
java.io.Serializable interface to serialize an object.
Let’s understand the concept of Serialization with the
help of an example.

This class defines two methods – deserialize and serialize.
In the deSerialize method the path and file name of the file is
called. This file contains the byte stream of object’s state. Once
the file name and path are called the deSerialize method returns
the object that can be down casted to the corresponding serialized
class object. During deSerialize method we open the file in read
mode using FileInputStream class and pass the object to
BufferedInputStream class constructor. The object is then passed
to the constructor class ObjectInputStream while instantiating. In
ObjectInputStream class we call the readObject() method which
will carry out the actual deserialization.
10. Copyright @ 2015 Learntek. All Rights Reserved. 10
In the serialize method there are two parameters i.e., file
path & name and data object which is required to be
serialized. In this method we first open the file in write
mode using FileOutputStream class and pass the object
to BufferedOutputStream class constructor. Then the
object is passed to ObjectOutputStream class while
instantiating and writeObject() method is called to
serialize the data object and write byte stream into
opened file.
11. Copyright @ 2015 Learntek. All Rights Reserved. 11
There are certain fields in the class of an object which
you may not want to serialize such as sensitive
information (keys, password, etc.). We protect those
fields from getting saved during the process of
serialization. Using the keyword transient before any
field of an object won’t get serialized since transient
objects are not eligible for serialization. When
deserialized the value of these transient fields will have
the default value.
