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.
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.

2. Texture analyzer
Texture Profile Analysis is a popular double compression test for determining the textural properties of
foods.
During a TPA test samples are compressed twice using a texture analyzer to provide insight into how
samples behave when chewed.
The TPA test was often called the "two bite test" because the texture analyzer mimics the mouth's biting
action.
4. Mechanism of texture analyzer
• The principle of a texture measurement system is physically deforming a
test sample in a controlled manner and measuring its response.
• Characteristics of the force response are the result of the sample's
mechanical properties, that correlate to specific sensory texture attributes.
• Forces created during this movement are manipulated to recreate
consumer interactions. For example, the conditions that foods are exposed
to when eaten or processed.
• There are some fundamental test methods designed to deform samples in
ways that simulate complex human interactions and replicate such
conditions. We have a wide range of standard and customized fixtures for
such test types.

15. Kramer Shear Cell
• Multiple blade test is recommended for products with variable structure
either due to nature (fruits, vegetables, meat) or design (breakfast
cereals, cereal bars, pasta shapes).
• Examples: Kramer Shear Cell or Mini Ottawa/Kramer Shear Cell
Kramer Shear Cell

16. Back Extrusion Test
• A rod with a disc is then forced down
into the container until the food flows up
(backwards) through the space between
the disc and the container walls which is
called the annulus.
• Examples: yoghurt, creams and
sauces, processed fruit and
vegetables, or moisturising creams,
shampoo and hair gel products
17. Forward Extrusion Test
Measures the compression force required
for a piston disc to extrude a product
through a standard size outlet in the base
of the sample container.
Examples: baking fats, sauces, pastes,
gels and viscous liquids OR creams,
pastes, gels and viscous liquids
18. Bending / snapping Test
• This type of test can measure the fracture and break strength of
hard and brittle products (or their flexibility) by bending the
sample, usually until a break occurs.
• Fracturability/brittleness/crispness

circular support, up to the point of fracture.
Results Force
Accessories • Circular Support Insert (1 No.)
• P/0.25 S Stainless Steel Ball Probe (1 No.)
20. SPAGHETTI FLEXURE RIG
• The SPAGHETTI FLEXURE RIG (A/SFR)
measures the compression and flexure
characteristics of uncooked spaghetti for
packaging and transportation.
• The test sample is located between upper and
lower supports in centrally located holes. The
upper support is directly connected to the loadcell
and the lower support to the base of the texture
analyser. Test samples of 100mm are prepared
and the average force and distance to break is
measured.
21. Tension test
• A tensile test pulls or stretches a sample and as a result the extensibility/elongation and tensile
strength properties are measured in terms of force required to stretch and distance or time upto
which something can be stretched to.
• The specimen is gripped at either end and stretched until it breaks. This is uniaxial tension.
• Another approach is to perform a bi-axial tensile test where the sample is held like a circular drum
skin and stretched in all directions by forcing a ball probe through the centre. This type of testing is
popular for testing films and certain foods e.g. tortillas where the measurement of burst strength is
required.
• e.g. films, dough, gels, spaghetti, confectionery , packaging materials and adhesives
