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.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

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.

Title: Marsh Funnel Viscometer
Experiment No.: 4
Name: Muhammad Sulaimon Rasul
Group: B2
Date: 7 OCT 2019
Supervisors: Jagar Ali, Fouad Yossifi, Rawezh Najat
3. Aim
The aim of experiment is finding a drilling mud viscosity which composed of bentonite and water
using a viscometer.
Theory
Drilling mud is a mixture of water and mud (Clay) addition to some other minerals and special
chemical materials called “additives” (Kate, 1998), that used with water and mixed to maintain
well stability during the process of drilling. Sometimes mud can be non-aqueous regarding to well
condition that can be Oil-Base Mud used (Simon, 2017). A Successful drilling operation is
requiring a good quality of drilling fluid (Darley et al.,1988).
The composition that required for drilling mud is depend upon the formation stability which wells
are drill through formations with a different type of compositions that require different types of
mud composition (Simon, 2017). The liquid-based mud which usually composed of a based fluid
such as (Oil or Water) with some weighting additives such as Bentonite and Barite. (Ofi Testing
Equipment inc.,2003).
The density of drilling mud is one of the important parameters which should be first considered. It
was a definition regarding to American Petroleum Institute is matter measured per unit volume
which expressed in pounds per gallon (ppg) (Simon, 2017).
The density is one of parameters that controls formation pressure to avoid the blowout, and it
should be accurately measured in order to provide a sufficient hydrostatic pressure over the
formation pressure to avoid lost circulation (Geehan et al.,1989; Kruse, 1975).
Another important parameter that effects on mud efficiency is viscosity of mud. The viscosity is
defined as the resistance to flow. Viscosity is measured by a simple device named funnel
viscometer which has conical shape – 152 mm (6") in dimeter at the top and 305 mm (12in) is long
with the volume of 1500 cc. Also, there is a mesh screen covered a half top of the funnel which
designed to remove any impurities such as drilling cuttings. The concept is the drilling fluid should
pass through the orifice in a period of time (second) then recorded to an equation (1) to get effective
viscosity in cp(s). (Pitt, 2000).

5. Calibration
Calibration should be executed for the viscometer for being sure if the it is working correctly or
not. However, there is a procedure for calibrating viscometer as the following steps:
1. First clean the funnel and cup of viscometer, then fill the funnel with water till 1500 ml but
a finger should be put against the bottom of the funnel.
2. Now, set a timer to 00:00 and bring a cup and put a funnel into it then remove a finger; let
all water pour inside the cup. While a finger removed timer should start.
3. Let water fill a cup till 946 ml then pause the timer directly.
4. The time should be 26±0.5 seconds, if it exceeded this range; the funnel assumed not
accurate.
NOTE: An error has been accorded about 0.13s below the 25.5s may due to late starting of timer
during the calibration which it was 25.37 seconds.

viscosity.

6. Procedure
1. First the volume of water must be calculated then regarding to the calculation, the amount
of water should be measured.
2. As the Bentonite has calculated in the calculations, Bentonite should measure using an
electronic balance.
3. Then take off all water inside the cup of electronic mixer and carefully turn it on.
4. Now while the mixer is working, add the Bentonite a little by little into the water to avoid
stacking of mixture.
5. After putting all Bentonite inside water while its mixing together, wait about 3-4 min till it
fully get mixed.
6. Now remove a cup from the mixer and take it to a clean beaker and put all mud into it then
clean the cup and do the same procedure about 5 more times to be sure that you get 1500
ml of drilling mud.
7. Now bring a funnel viscometer and fill it with the mud, be sure that you pour it from a filter
that fixed at the top of funnel to remove the impurities.
8. A figure should be put against the funnel outlet then pour the mud till you fill it until 1500
ml.
9. Now set a timer to 00:00 and start when the finger removed from the outlet instantly.
10. Let the mud fill the cup until 946 cc. When it gets to 946 ml stop the timer and record it.
11. Clean all used apparatus.

8. Result and Discussion
Table 1: Experimental and Theorical Results
Materials Volume (cc) Density (ib/gal) Mass (gm)
Water 291.099 8.33 -
Bentonite Clay 8.901 20.8 22.2525
Drilling Mud 300 8.7 -
Final Mud Volume 1500 8.7 -
Viscosity of Mud = 34.32 cp
Regarding to the table 1, results are quite good theatrically. The density of mud has also measured
experimentally which was 8.7ppg on the mud balance. During the procedure, starting the timers
also may some errors about some milliseconds to one second which can be ignored. Funnel
viscometer should also fix at a point and do not move while the mud pouring to the cup and also
should has no slops as well to avoiding any kind of errors. The mud viscosity is directly
proportional to the mud density in other words depend on the concentration of solid particles.
However, the mud viscosity will directly have effect on the flow rate of mud and also effect on
mud pumps, in case of high viscosity mud requires more powerful pump.
Conclusion
Performing this kind of experiment’s make students engage more and gain ability to generate
drilling mud as recommended and be able to measure its viscosity by a simple technique using
funnel viscometer and an equation for finding effective viscosity.
