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.
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.

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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Rotary Kiln Application
Rotary kiln is a rotating cylindrical vessel which is used for drying, calcination and sintering in a continuous process with
the use of hot gases. The hot gases may be generated in an external furnace or by a flame inside the kiln. Dajia rotary kiln
and sponge iron rotary kiln has been developed for performing drying, calcination and sintering work in a continuous
process. Widely used for cement, pet coke calcination, dolomite, bauxite, sponge iron and other materials, it uses hot gases
for the operation. Integrated with variable speed drive, process automation and instrumentation, this kiln ensures optimum
operational control. In addition to technology, its design features better inlet and outlet sealing to ensure minimum false air
entry.

Structure Feature
Kiln shell degree of natural deflection and rotation angle of kiln supports are carefully designed, which extends the service
life of refractory lining
Kiln support rollers are equipped with floating roller bearings with large diameter and small L/D for higher reliability
Rotary kiln seals to the kiln inlet, which serve as an insulation layer and increase service life.

Support roller
In order to ensure uniform use of the contact surfaces between tyres and supporting rollers, as well as the girth gear and
pinion, the axial motion of the rotary kiln is controlled. The support roller mechanism counteracts the forces which are
generated by the slope of the kiln. It operates automatically and is controlled by non-contact.
Kiln Tyre
5. The purpose of tyres (often called riding rings) and rollers
is to support the kiln and allow it to rotate with minimal
friction. Rotary kilns are among the largest items of
permanently moving industrial machinery, the largest
examples weighing in their fully-loaded form several
thousand tonnes. Despite the challenges of their size and
their high temperature, the best examples of rotary kiln
rotate on their rollers almost frictionlessly, the power
supplied by the drive being almost entirely in order to
oppose the eccentric load of the contents of the kiln. On
cutting the power to a kiln, the kiln will “roll back” and
unless a brake is applied, will continue to swing like a
pendulum for ten or fifteen minutes before coming to a
standstill. This finely-tuned mechanical condition requires
sophisticated design of the kiln’s supports.
Advantages of Roller Kiln
The unique structure design of splined tyre and shell shim plate guarantees the 100% synchronous operation of shell and
tyre; it can also transform the radial force along shell to the tangential. In this way, the deformation of shell could be
effectively restricted and the service life of refractory brick is prolonged.
Self-alignment kiln support guarantees the 100% contact of support roller and tyre and high transmission efficiency, so as to
prolong the service life of cast and forge parts.
Kiln drive via support rollers is characterized by compact layout, stable operation, reliable performance and low
maintenance.
Kiln Ring Gear
Ring Gears are also known as starter ring and comprises medium
carbon steel ring with teeth which comes fitted on periphery of
flywheel of internal combustion engine generally in automotive
applications. With the teeth driven by smaller gear (pinion) of starter
motor, its primary use is in transferring torque from starter motor
pinion to flywheel/flexplate for engine rotation.
Kiln Inlet Seal
Kiln inlet seal will be of friction type ring. Two nos. rings, carrying wear shoe segments on face, with one ring being
rotating with Kiln, slide on face to face. The wear shoes are lubricated by high temperature grease. The sliding ring have
pneumatic cylinders, distributed equally on the periphery, which always keep both the shoe rings of primary seal in contact,
even during and upward-downward movement.
Kiln Discharge Seal
6. Discharge end seal is made up of radially placed overlapping segmented graphite blocks. This allows movement of shell in
radial and axial direction while effectively sealing.
