Numerical modeling in support of the characterization and remediation of impacted sediments can be a challenging task, particularly in environments where multiple physical processes influence sediment fate and transport. The interaction of various controls is particularly complex in estuarine settings, where riverine input, water levels, waves, and other coastal processes combine to create a seasonally dynamic environment. Modeling of such environments requires a comprehensive and integrated approach such that the effects of each process can be assessed individually, as these processes can be allowed to interact to reproduce the natural environment as faithfully as possible
Approach and Activities
This contribution describes the development and calibration of an integrated Delft3D numerical model that includes flow, sediment transport, wave processes, and vegetation. The model boundary conditions are based on data collected during a comprehensive field program. Field data were also used to calibrate various model input parameters (such as bed and vegetation roughness). The model was used to understand erosion and deposition during both low and high flow regimes, and thus to aid in understanding important controls on sedimentary dynamics during these predominant regimes.
Results and Lessons Learned
The integrated numerical model predictions capture important sedimentation, erosion, velocity, and water level patterns. Model predictions indicate that during periods of low riverine input, velocity patterns and sediment transport associated with periodic water level changes dominate. During riverine flood conditions flow and sedimentation patterns are controlled by the river itself. Integrated modeling of this setting, including calibration to field data provides a valuable tool for assessment of future conditions, and thus for remediating impacted sediments.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.

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.

2. Contents:-
Introduction
Reservoir capacity
Reservoir Sedimentation
Types of sediment
Causes of sedimentation
Reservoir sedimentation control
3. Introduction:-
what is a Reservoir ?
It is an area developed by water
body due to construction of dam.
4. Reservoir capacity:-
Depends upon the inflow available
and demand.
Inflow in the river is always greater
than the demand, there is no storage
required.
If the inflow n the river is small but
the demand is high, a large reservoir
capacity is required.
5. The required capacity for a reservoir
can be determined by the following
methods:-
1) Graphical method, using mass
curves.
2) Analytical method
6. Reservoir sedimentation:-
All rivers carry certain amount of water of
sedimentation which is produced due to
erosion in their catchment areas.
These sediments are deposited in the
reservoir on the upstream of the dam
because of reduction of velocity.
Sedimentation reduce the available
capacity of the reservoir.
Continuous sedimentation, the useful life
of the reservoir goes on decreasing.
7. If the soil in the catchment is loose and erodible,
the sediment load is large.
In case of catchments having steep slopes, the
sediment load is large because of high velocity of
water.
If the catchment area has no vegetal cover, the
soil is easily eroded and the sediment load is
large.
If the intensity of rainfall is high, the discharge in
the river is increased and the sediment load is
large.
8. Type of sediment
The sediment load carried by a river
may be divided into the following two
parts:-
1. Suspended load
2. Bed load
9. The suspended load is that part of
the sediment load which does not
move in contact with the bed of
the river.
It consists of relatively finer
materials.
Suspended load
10. The bed load is that part of the
sediment load which moves in
contact with the bed of the river.
It consists of relatively coarser
materials.
Bed load
11. Causes of sedimentation
Nature of soil in the catchment area
Vegetation cover in the catchment area
Topography of the catchment area
Intensity of rainfall
Cultivation of land
12.
13. Density currents:-
Density current may be defined as a flow
of one fluid under another fluid of a
slightly different density under the effect
of gravity.
In may reservoir density current are
usually developed, especially during flood
when rivers carry heavily sediment- laden
or muddy water.
14. Measurement of sediment load:-
The suspended sediment load of a stream
is measured by taking the samples of
water at various depths.
The samples are weighted and filtered to
remove the sediment.
The sediment is then dried and weighted.
The sediment load is expressed in ppm
(parts per million)
16. Trap efficiency:-
Trap efficiency is defined as the percentage
of the sediment deposited in the reservoir
even inspite of taking precautions and
measures to control its deposition.
17. Reservoir sedimentation control :-
In order to increase the useful life
of a reservoir, the rate of
deposition of sediments in the
reservoir should be decreased.
18. Precautions of sedimentation control
Selection of suitable site
Proper design
Control of sediment inflow
a) check dam b) vegetation screens
Control of sediment deposition
Removal of sediment deposits
Soil conservation
