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.
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.

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.

Definitions related to compressor
⦿Compression ratio:-
It is defined as the ratio of volume of air before
compression to the volume of air after compression.
⦿Compressor capacity:-
It is the quantity of air actually delivered by a
compressor in m3 per minute.
7.
Definitions related to compressor
⦿Free air Delivered(FAD):-
It is the volume of air delivered by compressor under
the conditions of temperature and pressure existing at the
compressor intake.
⦿Swept Volume:-
The volume displaced or swept by piston when
it moves between top dead center and bottom dead
center.
8.
Types of Compressors
⦿Positive Displacement (PD) : Operate by trapping a
specific volume of air and forcing it into a smaller
volume
◾ 2 Basic Designs for PD Compressors
Rotary
Reciprocating
⦿Centrifugal : Operate by accelerating the air and
converting the energy to pressure
◾ 2 Basic Designs for Centrifugal Compressors

9.
Reciprocating Compressor
In a reciprocating compressor, a volume of air is
drawn into a cylinder, it is trapped, and compressed
by piston and then discharged into the discharge
line. The cylinder valves control the flow of air
through the cylinder; these valves act as check
valves.
There are two types of reciprocating compressor.
10.
Reciprocating Compressor
Single – Acting compressor
It is a compressor that has one discharge per
revolution of crankshaft.
Double – Acting Compressor
It is a compressor that completes two discharge strokes
per revolutions of crankshaft. Most heavy-duty
compressors are double acting..
12.
Reciprocating Compressor
Different parts of double acting compressor are
listed below.

Advantages of multi-staging
⦿Reduction in power required to drive the
compressor.
⦿Better mechanical balance of the whole unit and
uniform torque.
⦿Increase in volumetric efficiency.
⦿Reduced leakage loss.
⦿Less difficulty in lubrication due to low working
temperature.
⦿Lighter cylinders can be used.
⦿Cheaper materials can be used for construction as the
operating temperature is lower.
19.
Efficiencies for compressor
⦿Volumetric efficiency:-
It is the ratio of actual volume of the free air delivered
at standard atmospheric condition in one delivery stroke
to the swept volume by the piston during the stroke.
⦿Isothermal efficiency:-
It is defined as the ratio of isothermal power to the
indicated power.
⦿Mechanical efficiency:-
It is the ratio of indicated power to the shaft(Brake)
Power.
20.
Rotary air compressor
⦿Rotary compressors (get their name from the
rotating motion of the transfer element) compress
gases with lobes, screws, and vanes into smaller
volumes.
⦿4 Primary Types of Rotary Compressors:
◾Rotary Screw
◾Sliding Vane
◾Lobe
◾Centrifugal
◾Axial flow
22.
Screw Compressors
Commonly used in industry.
It operates with 2 helical rotors that rotate toward each
other, causing the teeth to mesh.
As the left rotor turns clockwise, the right rotor rotates
counterclockwise. This forces the gases to become
trapped in the central cavity.
The 2 rotors are attached to a drive shaft and drive that
provide energy to operate the compressor.
Have an inlet suction line and outlet discharge port.
24. Vane Compressor
⦿Uses a slightly off-center rotor with sliding vanes to
compress air.
⦿Inlet air flows into the vanes when they are fully
extended and form the largest pocket. As the vanes
turn toward the discharge port, the gases are
compressed.
⦿As the volume decreases, the pressure increases until
maximum compression is achieved. Then the air is
discharged out the compressor.
26.
Lobe Compressor
Characterized by 2 kidney-bean shaped impellers
used to trap and transfer air.
The 2impellers move in opposite directions on
parallel mounted shafts as the lobes sweep across
the suction port.
Compressed gases are released into the discharge
line.
The lobes do not touch each other. A few clearing
exists between the casing and lobes.
28.
Centrifugal Compressor
Centrifugal compressors accelerates the velocity
of the gases (increases kinetic energy) which is
then converted into pressure as the air flow
leaves the volute and enters the discharge pipe.
Usually operate at speeds > 3,000 rpm.
Deliver much higher flow rates than positive
displacement compressors
29. Centrifugal Compressor
⦿Basic Components
◾Impellers, Vanes, Volutes, Suction Eyes,
Discharge lines, Diffuser Plates, Seals, Shaft,
Casing
◾Suction Vane Tips = Part of the impeller
vane that comes into contact with air first.
◾Discharge Vane Tips = Part of the impeller
vane that comes into contact with air last
32. Axial flow compressor
Composed of a rotor that has rows of fanlike
blades.
In industry, axial compressors are used a lot high
flows and pressures are needed.
Air flow is moves along the shaft.
Rotating blades attached to a shaft push air over
stationary blades called stators.
Stator blades are attached to the casing.
33.
Axial flow compressor
As the air velocity is increased by the rotating blades, the
stator blades slow it down. As the air slows, kinetic
energy is converted into pressure.
air velocity increases as it moves from stage to stage until
it reaches the discharge.
Multi-Stage axial compressors can generate very high flow
rates and discharge pressures.
Axial compressors are usually limited to 16 stages (due to
temperature/material limitations)
Pound for pound, axial compressors are lighter, more
efficient, and smaller than centrifugal compressors.
