2_Analogy btw science math and engineering and ED.pptxaabhishekkushwaha9
An analogy between SMEs (Small and Medium Enterprises) and design could be drawn in various ways, highlighting similarities in their characteristics, processes, or importance. Here's one analogy:
Foundation and Flexibility:
SMEs are often likened to the building blocks of an economy, providing the foundation for growth and innovation. Similarly, design serves as the foundation for products, services, and experiences, shaping their functionality, usability, and aesthetics.
Just as SMEs need to be flexible and adaptable to changing market conditions, design also requires flexibility to meet evolving user needs, technological advancements, and design trends.
Problem-Solving Approach:
SMEs typically thrive by addressing niche markets, solving specific problems, or fulfilling unmet needs. Similarly, design is fundamentally about problem-solving, whether it's improving user experiences, optimizing efficiency, or enhancing aesthetics.
Both SMEs and design involve identifying challenges, brainstorming solutions, and implementing strategies to achieve desired outcomes.
Biomedical engineers design electrical circuits, software to run medical equipment, or computer simulations to test new drug therapies. In addition, they design and build artificial body parts, such as hip and knee joints. In some cases, they develop the materials needed to make the replacement body parts among others. The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered though the part(s) that get iterated and the number of such cycles in any given project may vary.

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.

Engineering design is the set of decision-making processes
and activities used determine the form of an object given the
functions desired by the customer.
Engineering design is the process of devising a system,
component, or process to meet desired needs. It is a
decision-making process (often iterative), in which the basic
science and mathematics and engineering sciences are
applied to convert resources optimally to meet a stated
objective. Among the fundamental elements of the design
process are the establishment of objectives and criteria,
synthesis, analysis, construction, testing and evaluation.

a need
Sometimes, but rarely, the need itself be original
Original designs occur rarely, but when occurs they
usually disrupt existing markets
37
37. Adaptive design
Occurs when the design team adapts a known
solution to satisfy a different need to produce a
novel application
Adaptive designs involve synthesis
Relatively common in design
38
38. Redesign
Employed to improve an existing design
Redesign to reduce failure in service, or to
redesign a component so as to reduce its cost
Accomplished without any change in the
working principle or concept of the original
design
Redesign by changing some of the design
parameters, it is often called Variant design
39
39. Other types of design
Selection design
Most of products employ standard components
Selecting the components with the needed
performance, quality, and cost
Industrial design
Deals with improving the appeal of a product to
the human senses, especially its visual appeal
More artistic than engineering
Consideration of how the human user can best
interface with the product
