Introductio to Abstract Window Toolkit (AWT)Ashita Agrawal
Abstract window toolkit is collection of classes and interfaces. The major advantage of AWT is Applets.
Applets interact with the user through the AWT and not through the console-based I/O classes.
The Awt contains support for a window based graphical Interface.
The AWT is huge collection of classes and interfaces.
Following table contains the list of classes present in jav.awt package.
Java.awt package is one of Java’s largest packages. Since AWT classes are logically organised in a top-down, hierarchical fashion, it is easy to understand and use them.
UML stands for Unified Modelling Language.
UML is a standard language for specifying, visualizing, constructing, and documenting a system in which software represents the most significant part.
UML is different from the other common programming languages like C++, Java, COBOL etc.
UML is a pictorial language used to make software blue prints.
UML can serve as a central notation for software development process. Using UML helps project teams communicate, explore potential designs, and validate the architectural designs of software.
UML diagrams are made using notation of things and relationships.
The building blocks of UML can be defined as:
Things
Relationships
Diagrams
Things: Things are the most important building blocks of UML. Things can be:
Structural
Behavioral
Grouping
Annotational
The Structural things define the static part of the model. They represent physical and conceptual elements. Following are the brief descriptions of the structural things.
Class: Class represents set of objects having similar responsibilities.
Interface: Interface defines a set of operations which specify the responsibility of a class.
Collaboration: Collaboration defines interaction between elements.
Use case: Use case represents a set of actions performed by a system for a specific goal.
Component: Component describes physical part of a system.
Node: A node can be defined as a physical element that exists at run time.
A behavioral thing consists of the dynamic parts of UML models. Following are the behavioral things:
Interaction: Interaction is defined as a behavior that consists of a group of messages exchanged among elements to accomplish a specific task.
State machine: State machine is useful when the state of an object in its life cycle is important. It defines the sequence of states an object goes through in response to events. Events are external factors responsible for state change.
SET
A set is a well defined collection of objects, called the “elements” or “members” of the set.
A specific set can be defined in two ways-
If there are only a few elements, they can be listed individually, by writing them between curly braces ‘{ }’ and placing commas in between. E.g.- {1, 2, 3, 4, 5}
The second way of writing set is to use a property that defines elements of the set.
e.g.- {x | x is odd and 0 < x < 100}
If x is an element o set A, it can be written as ‘x A’
If x is not an element of A, it can be written as ‘x A’
Special types of sets-
Standard notations used to define some sets:
N- set of all natural numbers
Z- set of all integers
Q- set of all rational numbers
R- set of all real numbers
C- set of all complex numbers
TYPES OF SETS
-subset
-singleton set
-universal set
-empty set
-finite set
-infinte set
-eual set
-disjoint set
-cardinal set
-power set
OPERATIONS ON SET
The four basic operations are:
1. Union of Sets
2. Intersection of sets
3. Complement of the Set
4. Cartesian Product of sets
Union of two given sets is the smallest set which contains all the elements of both the sets.
A B = {x | x A or x B}
Let a and b are sets, the intersection of two sets A and B, denoted by A B is the set consisting of elements which are in A as well as in B
A B = {X | x A and x B}
If A B= , the sets are said to be disjoint.
If U is a universal set containing set A, then U-A is called complement of a set.

Introduction:
Mohandas Karamchand Gandhi was born on 2 October 1869 in Porbandar, a coastal town in present-day Gujarat, India. His father, Karamchand Gandhi (1822–1885), who belonged to the Hindu Modh community, was the diwan (Prime Minister) of Porbander state, a small princely state in the Kathiawar Agency of British India.
Social Position:
Gandhi was born into the second highest caste in Hindu society – the Ruler-Warrior Caste.
As a youth (about 15-years-old):
He had his schooling in nearby Rajkot, where his father served as the adviser or prime minister to the local ruler. In May 1883, the 13-year old Mohandas was married to 14-year old Kasturbai Makhanji in an arranged child marriage, as was the custom in the region. In 1885, when Gandhi was 15, the couple's first child was born, but survived only a few days;
Later Teen Years:
On 4 September 1888, less than a month shy of his 19th birthday, Gandhi traveled to London, England, to study law at University College London and to train as a barrister. His time in London, the Imperial capital, was influenced by a vow he had made to his mother in the presence of the Jain monk Becharji, upon leaving India, to observe the Hindu precepts of abstinence from meat, alcohol, and promiscuity.
Gandhi in South Africa: 1893- 1914 :
In South Africa, Gandhi faced discrimination directed at Indians. He was thrown off a train at Pietermaritzburg after refusing to move from the first class to a third class coach while holding a valid first class ticket. Traveling farther on by stagecoach he was beaten by a driver for refusing to travel on the foot board to make room for a European passenger. These events were a turning point in his life, awakening him to social injustice and influencing his subsequent social activism.
The South Africa Years :
Gandhi served in and lead an Ambulance Corps Unit in both the Boer War 1899-1892 and the Zulu War of 1906. By supporting the British government, Gandhi hoped to gain full citizenship for Indians in South Africa, a goal he did not achieve.
Returning to India in 1915:
In 1915, Gandhi returned from South Africa to live in India. He spoke at the conventions of the Indian National Congress, but was primarily introduced to Indian issues, politics and the Indian people by Gopal Krishna Gokhale, a respected leader of the Congress Party at the time.
Role in World War I :
In April 1918, during the latter part of World War I, Gandhi was invited by the Viceroy to a War Conference in Delhi. Perhaps to show his support for the Empire and help his case for India's independence, Gandhi agreed to actively recruit Indians for the war effort. In contrast to the Zulu War of 1906 and the outbreak of World War I in 1914, when he recruited volunteers for the Ambulance Corps, this time Gandhi attempted to recruit combatants.
Cloud computing - new class of network based computingAshita Agrawal
Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet,
-basically a step on from Utility Computing
-a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform).
The hardware and software services are available to
general public, enterprises, corporations and businesses markets.
TYPES OF CLOUD:
There are different types of clouds that you can subscribe to depending on your needs. As a home user or small business owner, you will most likely use public cloud services.
1.public
2.hybrid
3.community
4.private

Conclusion
The cloud provides many options for the everyday computer user as well as large and small businesses. It opens up the world of computing to a broader range of uses and increases the ease of use by giving access through any internet connection.
However, with this increased ease also come drawbacks. You have less control over who has access to your information and little to no knowledge of where it is stored.
You also must be aware of the security risks of having data stored on the cloud. The cloud is a big target for malicious individuals and may have disadvantages because it can be accessed through an unsecured internet connection.
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.

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.

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.

3. CONCEPT OF CONSTRUCTOR
• A constructor is a special member function
whose task is to initialize the objects of that
class.
• It is special because its name is the same as
the class name.
• Constructor is invoked whenever an object of
the associated class is created.
• It is called constructor because it constructs
the values of data members of the class.
4. TYPES OF CONSTRUCTOR
• Default constructor:
A constructor that accepts no parameters is called
the default constructor.
• Parameterized constructor:
The constructor that can take arguments is called as
parameterized constructor.
• Copy constructor:
a constructor can accept a reference to its own class
as a parameter which is called as copy constructor.
5. OVERLOADED CONSTRUCTOR
• When more than one constructor function is
defined in a class, we say the constructor is
overloaded.
6. DESTRUCTOR
• A destructor, as the name implies is used to
destroy the objects that have been created by
a constructor.
• Like a constructor, the destructor is also a
special member function whose name is the
same as the class name but is preceded by a
tilde(~).
• Example: the destructor for class integer can
be defined as shown below
~integer() {}
7. DESTRUCTOR
