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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

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.

1.0 Introduction to Levelling
Levelling is the determination of the relative heights (altitudes) of the different points in
the area under survey, it is this information which, when coupled with that of the pan, enables a
section through the land and/or artefacts to be drawn (Clancy, 1991).
A horizontal line (or plane) of sight (line or plane of collimation) is established with a
telescope (fitted with cross-hairs) which can be turned about a vertical axis. The difference in
consecutive readings taken on a vertical staff gives the level difference between two points
which can be seen in the figure below.

Backsight (B.S.) - The first reading from a new instrument position.
Intermediate Sight (I.S.) – Readings between the backsight (B.S.) and foresight (F.S.)
Foresight (F.S.) - The last reading from an instrument position.
There leveling has two type of layouts which are the rise and fall method and the height
of collimation method.

6.0 Summary
In this fieldwork, the reduced level of Bench Mark (BM) 1 is given which is 100.00m. The
leveling process begins with obtaining the backsight (BS) of BM1 and the foresight (FS) of
turning point (TP) A. Then the auto level is shifted to obtain the BS of TP A and the FS of TP B.
This process is repeated by shifting the auto level to obtain the BS and FS of the following staff
stations and lastly go back to BM1 to obtain its FS in order to calculate the error of misclosure.
We used both the rise and fall method and the height of collimation method to calculate
the reduced level of each staff station. The error of misclosure was -0.006mm and the
acceptable range of error of misclosure was calculated using the 12+/- √k formulae where k
BQS MARCH 2014- QSB 60103 Fieldwork 1 Report
14. 14 | P a g e
represents the number of set-ups, and the acceptable range of error of misclosure is +/-
37.947mm. Thus, our leveling is acceptable.
To distribute the error, the correction per set-up is calculated using the following
formulae:
Correction per set-up
= Error of misclosure ÷ Number of set up
The correction per-set up is +0.0006m and is cumulative as shown in the table provided
in the adjusted data section.
