Difference between quantitative and qualitative researchSafi Nawam
Researchers usually work within a paradigm that is consistent with their world view, and that gives rise to the types of question that excite their curiosity.
The maturity of the concept of interest also may lead to one or the other paradigm: when little is known about a topic, a qualitative approach is often more fruitful than a quantitative one

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.

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.

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.

design
• Avoid complexity: Use simple conversational
language
• Avoid leading and loaded questions (question
that suggests a socially desirable answer or is it
emotionally charged)
• Avoid ambiguity :Be specific as possible
• Avoid double barreled items
• Avoid burdensome questions that may tax
respondent's memory
67. Data preparation process
• Preparing preliminary plan of data analysis
• Questionnaire checking
• Editing
• Coding
• Transcribing
• Data cleaning
• Statistically adjusting the data
• Selecting a data analysis strategy
68. Univariate, bivariate and multivariate
data
• Types of data based on number of variables
– Univariate :Analysis are made only based on one
variable
– Bivariate: Two variables
– Multivariate :Two or more variables
70. Hypothesis testing
• What u normally do
– If calculated value is less than the table value-
hypothesis accepted
– If calculated value is more than the table value-
hypothesis rejected
• How you do in SPSS?
– If the p value is > .05 – The result is insignificant
– If the p value is < .05 – The result is significant
71. Chi square tests
• Chi-square is a statistical test commonly used to
compare observed data with data we would
expect to obtain according to a specific
hypothesis.
• The chi-square test is always testing what
scientists call the null hypothesis, which states
that there is no significant difference between
the expected and observed result.
• We want to compare our observed data to what
we expect to see. Due to chance? Due to
association?
72. Assumptions:
• Independent observations
• A sample size of at least 10
• Random sampling
• All observations must be used
• For the test to be accurate, the expected frequency
should be at least 5
73. Conducting Chi-Square Analysis
1) Make a hypothesis based on your basic biological
question
2) Determine the expected frequencies
3) Create a table with observed frequencies, expected
frequencies, and chi-square values using the formula:
(O-E)2
E
4) Find the degrees of freedom: (c-1)(r-1)
5) Find the chi-square statistic in the Chi-Square
Distribution table
6) If chi-square statistic > your calculated chi-square value,
you do not reject your null hypothesis and vice versa.
