The document discusses methods for calculating condensate loads from steam systems, including warm up load from heating pipes and fittings, normal radiation loss once at operating temperature, and total peak condensate load for sizing steam traps. It provides equations to calculate the warm up load based on pipe weight and time, and the radiation load based on pipe length and temperature differential. The total peak load is the warm up load plus half the radiation load. Examples are given to demonstrate calculating the warm up and radiation loads for a 1000 foot section of 10 inch uninsulated pipe.

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.
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.

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.

Calculating Condensate Loads
Warm Up Load ( Heating Loss )
This is the amount of condensate which forms at starting up a power plant to raise the
temperature of the metal of pipes, fittings, etc. to the operating temperature without including the
normal radiation loss. As far as calculating the condensation load during the warming up period
the required time is extremely important for sizing steam traps. Less warm up time increases the
necessary capacity per trap. Allowing more time for warm up permits the use of smaller traps in
smaller quantity.
W x (T-t) x Sp. Heat x 60
Q = —————————————
L x m
Where Q = Quantity of Condensate ( Lbs/hr )
W = Total weight of pipes in LBS
T = Saturation Steam Temp ( °F )
t = initial temp of pipe ( °F ) usually surrounding air temp
m = minutes to heat up system
L = Latent heat of steam ( BTU’s/Hr )

Normal Condensate Load ( Radiation Loss )
Once the system is heated up steam condenses due to normal radiation losses to the
surrounding air. These losses depend of course on the size and length of the pipe, on the
pressure of steam and its latent heat and mainly on the type and thickness of insulation. The
equation from which a normal regulation load can be calculated is:
F x HL ( T - t )
Q = ——————————
L
Where F = Length of Pipe (ft)
HL ( T – t ) = Heat loss/foot of pipe at the temperature differential between steam and air
Above Table
L = Latent heat of steam ( BTU’s/Hr. )

Condensation Load for Sizing Steam Traps
The condensation load builds up from 0 to maximum at the point where the warming up load
drops to 0. It is assumed, therefore, that the peak is achieved halfway through the warming up
period. Therefore, for sizing of steam traps, we take the maximum amount of condensate during
the warming up period plus half of the radiation load.
Qt= QW + .5QR
Where Qt = Total condensation load at peak (LBS/Hr)
QW = Condensation load during warm up (LBS/Hr)
QR = Condensation load due to normal radiation loss (LBS/Hr)
Condensate in LBS/Hr created in steam mains 1” to 24” and pressure of 600 to 2500 PSI based
on the warm up period of 1 hour and 100 feet of pipe, and based on the above assumption is
shown in tables.
For shorter or longer heating up time, multiply by 60/m where m is the warm up time in minutes.
