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.

Unified Modeling Language (UML) is a general purpose modelling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering.
UML is not a programming language, it is rather a visual language. We use UML diagrams to portray the behavior and structure of a system. UML helps software engineers, businessmen and system architects with modelling, design and analysis. The Object Management Group (OMG) adopted Unified Modelling Language as a standard in 1997. Its been managed by OMG ever since. International Organization for Standardization (ISO) published UML as an approved standard in 2005. UML has been revised over the years and is reviewed periodically.

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.

3. Object-Oriented Modeling and Design is a way of
thinking about problems using models organized
around real world concepts. The fundamental
construct is the object, which combines both data
and behavior.
Object-Oriented means that we organize software
as a collection of discrete objects that incorporate
both data structure and behavior.
OO generally includes four aspects:
1. Identify
2. Classification
3. Inheritance
4. Polymorphism
3
INTRODUCTION TO OBJECT ORIENTATION
4. OBJECTS
An object has:
state - descriptive characteristics
behaviors - what it can do (or what can be done to it)
4
Objects have three responsibilities:
What they know about themselves – (e.g., Attributes)
What they do – (e.g., Operations)
What they know about other objects – (e.g., Relationships)
6. WHAT IS UML?
UML: Unified Modelling Language
An industry-standard graphical language for
specifying, visualizing, constructing and
documenting the software systems, as well as for
business modeling.
The UML uses mostly graphical notations to
express the OO modeling and design of software
projects.
Simplifies the complex process of software design
6
7. WHY WE USE UML?
Use graphical notation: more clearly than natural
language and code.
Help acquire an overall view of a system.
UML is not dependent on any one language or
technology.
7
8. MODELING AS A DESIGN TECHNIQUE
What is Modelling?
Modeling consists of building an abstraction of reality.
Abstractions are simplifications because:
They ignore irrelevant detailsand
They only represent the relevantdetails.
W h at is relevant or irrelevant depends on the purpose of the
model.
8
9. MODELING CONCEPTS
A model is an abstraction, before building any system
a prototype may be developed. The main purpose of
model is for understanding of the system.
Designer build different kinds of models for various
purposes before constructing things.
examples:
architectural models to show customers
airplane scale models
storyboards of advertisements
outlines of books
9
11. IMPORTANCE OF MODELLING
Models helpus
To visualize a system as it is or as we want it to be.
To specify the structure or behavior of a system.
I n providing a template that guides us in constructing a system.
I n providing documenting the decisions we have made.
11
12. ANALYSIS
All aspects of the problem domain need to be
investigated.
Decompose the problem into smaller problems until
the entire problem is fully understood.
The models that depict information, function, and
behavior must be constructed in a manner that
uncovers detail.
12
13. PURPOSES OF A MODEL:
Designers build many kinds of models for various
purposes before constructing things.
Models serve several purposes –
Testing a physical entity before building (simulation)
Communication with customer
Visualization
Reduction of complexity
Better understanding of the problem
13
14. ABSTRACTION
Fundamental human capability that permits us to deal with
complexity
Selective examination of certain aspect of problem
Abstraction must always be for some purpose, because the
purpose determines what is and is not important
“All abstractions are incomplete and inaccurate. Reality is
seamless web. Anything we say about it, and description of it,
is an abridgement. All human words and language are
abstractions—incomplete descriptions of the real world.”
“This does not destroy their usefulness. The purpose of an
abstraction is to limit the universe so we can do things.”
In building models, therefore you must not search for absolute
truth but for adequacy for some purpose. There is no single
correct model of a situation, only adequate and inadequate
ones. 14
15. BASICS OF THE THREE MODELS
What is model?
It is an abstraction of any system to understand it
before implement it.
There are three different types of model but
different viewpoints:
Class model: The static , ”structural”,” data aspects of a
system.
State model : The temporal , behavioural , “control”
aspects of a system.
Interaction model : The collaboration of individual
objects , the “interaction” aspects of a system.
Typically software use all the aspects : It uses data-
structures , sequences operations in time , and its passes
data and control among objects.
15
16. CONT…
The different models are not independent.
Each of the three models during development.
First analysts construct model without regard for
eventual during development.
Then designers add solution constructs to the
model.
Implement code both application and solution
constructs.
The model has two dimensions:
A view of a system
A stage of development
9/30/2019
16
17. CLASS MODEL
Class diagram is a static diagram.
It represents the static view of an application.
Class diagram is not only used for visualizing, describing, and
documenting different aspects of a system but also for
constructing executable code of the software application.
Class diagram describes the attributes and operations of a
class and also the constraints imposed on the system.
The class diagrams are widely used in the modeling of object-
oriented systems because they are the only UML diagrams,
which can be mapped directly with object-oriented languages.
Class diagram shows a collection of classes, interfaces,
associations, collaborations, and constraints.
It is also known as a structural diagram.
17
18. PURPOSE OF CLASS DIAGRAMS
The purpose of class diagram is to model the static
view of an application.
Class diagrams are the only diagrams which can be
directly mapped with object-oriented languages and
thus widely used at the time of construction.
Analysis and design of the static view of an
application.
Describe responsibilities of a system.
Base for component and deployment diagrams.
Forward and reverse engineering.

Class name
Alt 1 : datatype=default vaule
Alt 2: datatype=default value
Alt n : datatype=default value
OP1(arg_list) : Return type
It contains the name of
the class. It is printed in
bold and centered, and
the first letter is
capitalized.
contains the attributes
of the class. They are
left-aligned and the
first letter is lowercase.
contains the operations the
class can execute. They are
also left-aligned and the
first letter is lowercase.
21. STATE MODEL
The name of the diagram itself clarifies the purpose of the
diagram and other details.
It describes different states of a component in a system. The
states are specific to a component/object of a system.
A State diagram describes a state machine.
State machine can be defined as a machine which defines
different states of an object and these states are controlled by
external or internal events.
State model captures control.
State diagrams express the state model.
Each state diagram shows the states and events sequences
permitted in system for one class of objects.
Actions and events in a state diagram becomes operations on
objects in the class model.
21
22. PURPOSE OF STATE MODEL
State diagram describes the flow of control from one state to
another state.
States are defined as a condition in which an object exists and
it changes when some event is triggered.
The most important purpose of State diagram is to model
lifetime of an object from creation to termination.
State diagrams are also used for forward and reverse
engineering of a system.
To model the dynamic aspect of a system.
To model the life time of a reactive system.
To describe different states of an object during its life time.
Define a state machine to model the states of an object.
22
24. INTERACTION MODEL
From the term Interaction, it is clear that the diagram is used
to describe some type of interactions among the different
elements in the model. This interaction is a part of dynamic
behavior of the system.
This interactive behavior is represented in UML by two
diagrams known as Sequence diagram and Collaboration
diagram. The basic purpose of both the diagrams are similar.
Sequence diagram emphasizes on time sequence of
messages and collaboration diagram emphasizes on the
structural organization of the objects that send and receive
messages.
Use case documents major themes for interaction between
the system and actors.
24
25. PURPOSE OF INTERACTION MODEL
To capture the dynamic behavior of a system.
To describe the message flow in the system.
To describe the structural organization of the
objects.
To describe the interaction among objects.
25
26. HOW TO DRAW AN INTERACTION DIAGRAM?
We have two types of interaction diagrams in UML.
One is the sequence diagram and the other is the
collaboration diagram.
The sequence diagram captures the time sequence
of the message flow from one object to another and
The collaboration diagram describes the
organization of objects in a system taking part in
the message flow.
26
