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.

7. It Focused on 2 basic Fundamentals
• 1. Quality of Design:-
Characteristics of items or tools used by designer.
• 2. Quality of Conformance:-
Degree to which design specifications are followed in
manufacturing the product or software
37. SQA (via IEEE)
• “The Quality assurance process is a process for providing adequate assurance
that the software products and processes in the project life cycle conform to
their specified requirements and adhere to their established plans. “
• A planned and systematic pattern of all actions necessary to provide
adequate confidence that an item or product conforms to established
technical requirements.
• A set of activities designed to evaluate the process by which products are
developed or manufactured.
38. Software Quality Assurance
• IEEE 730 - Quality Assurance Plans
• “Quality Assurance - a planned and systematic pattern of all
actions necessary to provide adequate confidence that the time or
product conforms to established technical requirements.”
• Purpose of SQAP is to specify all the works products that need
to be produced during the project, activities that need to
performed for checking the quality of each of the work product
• It is interested in the quality of not only the final product but
also an intermediate product
• So it ensure that the delivered software is of good quality
39. SQA Life CYCLE or Framework of SQA
Design
Test
Deployment
Concept/ Requirements
Devel. & Coding
IV&V Risk Management
Metrics
Safety Reliability
40. Need of Quality Assurance Plan
• To ensure the final product produced is of high quality, some quality control
activities must be performed throughout the development
• If it is not done ,correcting errors in the final stage can be very expensive,
especially if they originated in the early phase.
41. Scope of quality management
• Quality management is particularly important for large, complex systems.
The quality documentation is a record of progress and supports continuity
of development as the development team changes.
• For smaller systems, quality management needs less documentation and
should focus on establishing a quality culture.
42. Quality management activities
• Quality assurance
• Establish organisational procedures and standards for quality.
• Quality planning
• Select applicable procedures and standards for a particular project
and modify these as required.
• Quality control
• Ensure that procedures and standards are followed by the software
development team.
• Quality management should be separate from project management to
ensure independence.
43. Verification & Validation
• Verification:-is the process of determine whether or not product
of a given phase of software development full fill the
specification established during the previous phase.
• Validation:-is the process of evaluating software at the end of
software development to ensure compliance with the software
requirement. testing is common method of validation
• Software V&V is a systems engineering process employing
rigorous methodologies for evaluating the correctness and quality
of the software product throughout the software life cycle
44. Verification (Are we building the
product right?)
Validation (Are we building the right
product?)
46. SEI Capability Maturity Model (CMM)
• The CMM was developed by software engineering institute (SEI)
of carnegie-mellon university in 1986.
• CMM is not a SDLC model. instead it is a strategy for improving
the software process.
• CMM is used to judge the maturity of the software processes of
an organization and to identify the key practice that are required
to increase the maturity of these processes.
47. Objectives of the CMM
To increase customer satisfaction, by producing products according
to plan while simultaneously improving the organization’s capability
to produce better products
To increase software process maturity, the extent to which
processes are explicitly defined, managed, measured, controlled,
and effective, by:
48. Objectives of the CMM
• Establishing basic project management controls
• Standardizing the organization's software process activities
• Quantitatively analyzing processes and products for monitoring
and control
• Institutionalizing process improvement
49. Capability Maturity Model (CMM)
It is a strategy for improving the software process, irrespective
of the actual life cycle model used.
52. CMM Building Blocks: the Maturity Levels
Institutionalize
process improvement
Quantitative analysis of processes
and products for monitoring and
control
Standardize the software
process activities for all
the organization’s projects
Establish basic project
management controls
53. ISO 9000 certification
• ISO (International Standards Organization) is a consortium of 63
countries established to formulate and foster standardization ISO
published its 9000 series of standards in 1987.
• ISO certification serves as a reference for contract between
independent parties
• ISO 9000 standard specifies the guidelines for maintaining a
quality system.
54. ISO 9000 certification
• Quality standards and procedures should be
documented in an organisational quality manual.
• An external body may certify that an organisation’s
quality manual conforms to ISO 9000 standards.
• Some customers require suppliers to be ISO 9000
certified although the need for flexibility here is
increasingly recognised.
55. ISO 9000 certification
• An international set of standards for quality management.
• Applicable to a range of organisations from manufacturing to service
industries.
• ISO 9001 applicable to organisations which design, develop and maintain
products.
• ISO 9001 is a generic model of the quality process that must be instantiated
for each organisation using the standard.
56. How to get an ISO 9000 Certification
• Application
• Pre-assessment
• Document review and adequacy of audit
• Compliance audit
• Registration
• Continued surveillance
57. Types of ISO 9000 quality standards
• ISO 9001 applies to the organizations engaged in design, development, production,
and servicing of goods. This is the standard that is applicable to most software
development organizations
• ISO 9002 applies to those organizations which do not design products but are only
involved in production. Examples of these category industries include steel and car
manufacturing industries that buy the product and plant designs from external
sources and are involved in only manufacturing those products.
• Therefore, ISO 9002 is not applicable to software development organizations.
• ISO 9003 applies to organizations that are involved only in installation and testing
of the products.
58. Need for obtaining ISO 9000 certification
• Confidence of customers in an organization increases when organization qualifies
for ISO certification. software organizations involved in software export to obtain
ISO 9000certification.
• ISO 9000 requires a well-documented software production process to be in place. A
well-documented software production process contributes to repeatable and higher
quality of the developed software.
• ISO 9000 makes the development process focused, efficient, and cost effective.
• ISO 9000 certification points out the weak points of an organization and
recommends remedial action.
• ISO 9000 sets the basic framework for the development of an optimal process and
Total Quality Management (TQM).

Deals primarily for manufacturing
industry and provisioning of services
It aims at level 3 of CMM
Has Customer Focus as primary aim
and follows procedural controls
SEI CMM assessment is purely for

higher level to provide gradual
Quality improvements
ISO CMM
Differences Between
61. Shortcomings of ISO 9000 certification
• ISO 9000 requires a software production process to be adhered to but does
not guarantee the process to be of high quality.
• It also does not give any guideline for defining an appropriate process.
• ISO 9000 certification process is not fool-proof and no international
accreditation agency exists. Therefore it is likely that variations in the norms
of awarding certificates can exist among the different accreditation agencies
and also among the registrars.
• ISO 9000 does not automatically lead to continuous process improvement,
i.e. does not automatically lead to TQM.
