The document discusses the purposes and steps of conducting engineering experiments. The main purposes are to reduce time to develop new products and processes, improve existing processes, improve product reliability and performance, and achieve product and process robustness. The most common purposes of experiments are to explore new technologies, develop an understanding of production factors, develop superior technologies, and identify optimal production levels. The key steps are recognizing the experimental goal, selecting factors and response variables, choosing a design, conducting the experiment, performing statistical analysis, and drawing conclusions.

In our newest case study, we outline our expertise in driving speed to clinical data and reducing development costs and time substantially.
Software Testing adds organizational value in quantitative and qualitative ways. Successful organizations recognize the importance of quality. Establishing a quality-oriented mindset is the responsibility of business leadership.
Geoff Thompson - Why Do We Bother With Test StrategiesTEST Huddle
EuroSTAR Software Testing Conference 2008 presentation on Why Do We Bother With Test Strategies by Geoff Thompson. See more at conferences.eurostarsoftwaretesting.com/past-presentations/
A test strategy is the set of ideas that guides your test design. It's what explains why you test this instead of that, and why you test this way instead of that way. Strategic thinking matters because testers must make quick decisions about what needs testing right now and what can be left alone. You must be able to work through major threads without being overwhelmed by tiny details. James Bach describes how test strategy is organized around risk but is not defined before testing begins. Rather, it evolves alongside testing as we learn more about the product. We start with a vague idea of our strategy, organize it quickly, and document as needed in a concise way. In the end, the strategy can be as formal and detailed as you want it to be. In the beginning, though, we start small. If you want to focus on testing and not paperwork, this approach is for you.

Testing is a process rather than a single activity. This process starts from test planning then designing test cases, preparing for execution and evaluating status till the test closure.

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.
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.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
1. AE 58 Experimental Design
for Agricultural Engineering
Modules and Laboratory Exercises
2. Engineering Experiments
If we had infinite budgets there probably wouldn't be a big fuss made
over designing
experiments. In production and quality control we want to control the
error and learn as much as
we can about the process or the underlying theory. From an
engineering perspective we're trying
to do use experimentation for the following purposes:
reduce time to design/develop new products & processes
improve performance of existing processes
improve reliability and performance of products
achieve product & process robustness
perform evaluation of materials, design alternatives, setting
component & system
tolerances, etc.
3. Most Common Purpose of Conducting Experiment
To explore new technologies, new crops, and new areas of
production
To develop a basic understanding of the factors that control
production
To develop new technologies that are superior to existing
technologies
To study the effect of changes in the factors of production and to
identify optimal
levels
To demonstrate new knowledge to growers and get feedback from
end – users about
the acceptability of new technologies
4. Steps for Planning, Conducting and Analyzing an Experiment
The practical steps needed for planning and conducting an
experiment include: recognizing
the goal of the experiment, choice of factors, choice of response,
choice of the design, analysis
and then drawing conclusions. This pretty much covers the steps
involved in the scientific
method.
1. Recognition of & statement of problem
2. Choice of factors, levels, and ranges
3. Selection of the response variable(s)
4. Choice of design
5. Conducting the experiment
6. Statistical analysis
7. Drawing conclusions, and making recommendation
