Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
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.

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.

6. Software is set of programs (which are
step by step instructions) telling the
computer how to process data.
Software's can be divided into two groups:
- System SW
- Application SW
7. System Software
It controls the overall operation of the system.
It is stored in the computer's memory and instructs
the computer to load, store, and execute an
application.
Examples: Operating System (OS), Translators
DOS, Windows, Unix etc.
8. Application Software
They are Software's written to perform specific tasks.
The basic types of application software are:
word processing, database, spreadsheet, desktop
publishing, and communication.
Examples: MSOffice, Tally, MSOutlook.
9. Speed: Computers can carry out instructions in less
than a millionth of a second.
Accuracy : Computers can do the calculations
without errors and very accurately.

"brain" of your computer.
• It contains various electronic circuits.
12. The keyboard looks like a typewriter.
It contains all the letters of the alphabet, numbers
and some special symbols.
It operates like a typewriter keypad, but instead of
moving an arm, which strikes the paper, it sends an
electronic impulse to the computer, which displays a
character on the monitor.
13. • Its a device that is used to control the
computer. A cable connects the mouse to the
computer.
• When the mouse is moved on a pad, called a
mouse pad, the cursor on the screen moves.
• A cursor is a small symbol displayed on the
computer screen (normally a diagonal arrow
that is used as a pointer) that shows you what
the mouse is referencing on the screen.
14. A printer is designed to output information from a
computer onto a piece of paper.
There are three kinds of printers:
dot matrix, laser, and inkjet.
15. A scanner is a device used to copy an image off paper
and convert it into a digital image, which can be saved
as a computer file and stored on a hard drive.
Scanners can also use a special kind of technology
called Optical Character Recognition (OCR) to read text
from paper and save it as an editable document file

currently using.
Hard Drive – (long-term memory) holds all of the
information that needs to be stored between uses of the
computer.
Floppy and CD-ROM drives – (mouth/ears) allow you to
give data to the computer and take data away from the
computer.
21. Card Slots – (fingers) Allows other components to be
added to the computer.
Video card – (face) Does all of the processing
necessary to get stuff looking nice on screen, quickly.
Sound card – (vocal cords) Allows sounds from HD or
CD-ROM to be played.
Network Card – (telephone) allows computer to talk to
other computers over a wire.
29. The central processing unit or (CPU) is the "brain" of your
computer. It contains the electronic circuits that cause the
computer to follow instructions from memory.
The CPU contains three main parts, all housed
in a single package (Chip):
• Control Unit (CU)
• Arithmetic Logic Unit (ALU)
• Memory
30. Keyboard
Mouse
Hard Disk
Floppy Disk
CD ROM
Printer
Scanner
Joystick
31. OS is system software, which may be viewed as
collection of software consisting of procedures
for operating the computer.
It provides an environment for execution of
programs (application software).
It’s an interface between user & computer.
