Drafting irregularities and their causes and remedies,Amount of draft and draft distribution on strand irregularity,Draft distribution,Recommended total draft range,Limitations of apron drafting and the scope for improvement.
Terry fabric is a knitted fabric with ring yarn or terry covering at one or both sides. It belongs to one of the fancy knitted fabrics. Terry fabric is characterized by soft touch, thick texture, excellent water absorption and heat retention. Terry fabric can be divided into single-sided and double-sided terry loop fabrics. The terry can form pattern effect on the knitting surface distributed according to some certain rules. Terry fabric after shearing or other process can be turned into fleece fabric or velvet fabric.
Ring, rotor, compact, air-jet and other forms of spinning are discussed in this presentation along with Illustrations. the crisp and clear explanation helps in understanding the basic know how of advance methods of spinning

Non woven
Nonwoven fabrics are broadly defined as sheet or web structures made of fibers or filaments bonded or interlocked together by mechanical, thermal, chemical or solvent means. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn.

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.
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.

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.

Classification of Non-woven
2. 1. Spun lace Non-woven Fabric
Spun lace process is high pressure micro flow injection into a layer or layers
of fibrous web, so that the fibers are twisted together, so that the web can
be strengthened and have a certain strength.
2. Non-woven Fabric
Thermal bonded nonwoven is defined in the web of fibrous or powder
adding hot-melt adhesive reinforcement material, web after heating melt
cooling reinforcement into cloth.
3. Pulp Air-laid Non-woven Fabric
Air-laid non-woven fabrics can be called clean paper, paper non-woven
fabrics. It is the use of air-laid pulp fiber plate technology will be opening a
single fiber state, and then use the airflow method of making fiber
agglutination in a curtain net, web reinforcement into cloth.
4. Wet Non-woven Fabrics
Wet non-woven fabric is placed in water medium fiber opening into single
fiber, while the different fiber raw material mixing, into the fiber
suspension slurry, suspension slurry to web forming mechanism, fiber in
wet state into net reinforcement into cloth.
3. Spun bonded Non-woven Fabric
Spun bonded non-woven fabric is in the polymer has been extruded,
stretched and form a continuous filament, filament laying into the net, the
web through the self bonding, thermal bonding, chemical bonding or
mechanical reinforcement method, make the web into a non-woven fabric.
Melt-Blown Non-woven Fabric
Melt blowing nonwoven process: polymer blend melt extrusion formation
– fiber – fiber cooling – Net – reinforcement into cloth.
