This document discusses different types of 2D and 3D transformations that are used in computer graphics, including translation, rotation, scaling, shearing, and reflection. It provides the mathematical equations and transformation matrices used to perform each type of transformation on 2D and 3D points and objects. Key types of rotations discussed are roll (around z-axis), pitch (around x-axis), and yaw (around y-axis). Homogeneous coordinates are introduced for representing 3D points.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
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.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

2. Transformations are a fundamental part of
the computer graphics. Transformations are
the movement of the object in Cartesian
plane .
3. There are two types of transformation in
computer graphics.
1) 2D transformation
2) 3D transformation
Types of 2D and 3D transformation
1) Translation
2) Rotation
3) Scaling
4) Shearing
5) Mirror reflection
4. Transformation are used to position
objects , to shape object , to change
viewing positions , and even how
something is viewed.
In simple words transformation is used for
1) Modeling
2) viewing
5. When the transformation takes place on a 2D
plane .it is called 2D transformation.
2D means two dimensional (x-axis and Y-axis)
Object Transformation in 2D
Alter the coordinates descriptions an object
Translation , rotation , scaling , shearing,
reflection.
Coordinate system unchanged
Coordinate transformation in 2D
Produce a different coordinate system
9. When the transformation takes place on a 3D
plane .it is called 3D transformation.
Generalize from 2D by including z coordinate
Straight forward for translation and scale, rotation

Homogeneous coordinates: 4 components
Transformation matrices: 4×4 elements

Vectors . Thus, a typical point with
coordinates (x, y, z) is represented as:

3D Point Homogenous Coordinate
A 3D point P is represented in homogeneous
coordinates by a 4-dim.
The main advantage:- it is easier to
compose translation and rotation

12. Moving of object is called translation.
In 3 dimensional homogeneous coordinate
representation , a point is transformed from
position P = ( x, y , z) to P’=( x’, y’, z’)
This can be written as:-
Using P’ = T . P

13. The matrix representation is equivalent to the three
equation.
x’=x+ tx , y’=y+ ty , z’=z+ tz
Where parameter tx , ty , tz are specifying translation
distance for the coordinate direction x , y , z are
assigned any real value.
Translate an object
by translating each
vertex in the object.
14. where an object is to be rotated about an axis that is
parallel to one of the coordinate axis, we can
obtain the desired rotation with the following
transformation sequence.
Coordinate axis rotation
Z- axis Rotation(Roll)
Y-axis Rotation(Yaw)
X-axis Rotation(Pitch)
15. Z-axis rotation is same as the origin about in 2D
for which we have the derived matrices already.
x’ = x cosθ – y sinθ
y’ = x sinθ – y cosθ
z’ = z

22. Reflection in computer graphics is used to
emulate reflective objects like mirrors and
shiny surfaces
Reflection may be an x-axis
y-axis , z-axis. and also in
the planes xy-plane,yz-plane , and
zx-plane.
Reflection relative to a given
Axis are equivalent to 180
Degree rotations
26. Modify object shapes
Useful for perspective projections
When an object is viewed from different
directions and at different distances, the
appearance of the object will be different.
Such view is called perspective
view. Perspective projections mimic what the
human eyes see.
E.g. draw a cube (3D) on a screen (2D) Alter the
values for x and y by an amount proportional to
the distance from zref
