In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NOx is produced in a narrow band of high cylinder temperatures and pressures.

This is a project I have done in my college as a final year project along with my friends, Aniket Anand, Madhuja Roy and Ananga Mohan Chatterjee. In this project, we have tries to use IoT. This is basically a spy robot car which is controlled using a self developed android app via bluetooth. In this ppt we have coveredd the technologies used and the algorithm behind the whole project. You can watch the demo of the application from the following link https://www.youtube.com/watch?v=BZ57YZiUQB4
The present condition in Industry is that they are using the crane system to carry the parcels from one place to another, including harbors. Some times the lifting of big weights may cause the breakage of lifting materials and will cause damage to the parcels too. Application of the proposed system is for industries. The robot movement depends on the track. Use of this robot is to transport the materials from one place to another place in the industry.
A robot is a machine designed to execute one or more tasks repeatedly, with speed and precision. There are as many different types of robots as there are tasks for them to perform. A robot can be controlled by a human operator, sometimes from a great distance. In such type of applications wireless communication is more important.
In robotic applications, generally we need a remote device to control. If we use IR remote device, it is just limited to meters distance and also if any obstacle is in between its path then there will be no communication. If we consider, RF modules for remote operations there is no objection whether an obstacle is present in its path. So that it is very helpful to control robot.
RF modules itself can generates its carrier frequency which is around 2.4 GHz. We need to generate serial data using micro controller and fed to the RF transmitting module. On other side RF receiver receives sent data as RF signals and given to another micro controller. Here, RF receiver itself demodulates the data from carrier signal and generate serial data as output.
This is kind of robot can be helpful for spying purpose in war fields. This project is designed to develop a robotic vehicle using RF technology for remote operation attached with wireless camera for monitoring purpose. The robot along with camera can wirelessly transmit real time video with night vision capabilities.
Robot which can be controlled remotely by an Android smartphone.
The robot works through a “AC Robot” android app. The app is designed by us and made available to open source. The app and source code can be downloaded from the url (http://tinyurl.com/kh7zgex).

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.

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.
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.

2. What is a Mobile controlled [DTMF] ROBOT?
DTMF Mobile ROBO is a machine that can be controlled with a mobile . In
this project, the robot is controlled by a mobile phone that makes a call to
the mobile phone attached to the robot. In the course of a call, if any button
is pressed, a tone corresponding to the button pressed is heard at the other
end of the call. This tone is called "Dual Tone Multiple-Frequency" (DTMF)
tone. The robot perceives this DTMF tone with the help of the phone
stacked on the robot. The received tone is processed by the microcontroller
with the help of DTMF decoder. The microcontroller then transmits the
signal to the motor driver ICs to operate the motors & our robot starts
moving
4. The DTMF technique outputs distinct representation
of 12 common alphanumeric characters (0-9, *, #) on
the telephone. The lowest frequency used is 697Hz
and the highest frequency used is 1633Hz.
The DTMF keypad is arranged such that each row will
have its own unique tone frequency and also each
column will have its own unique tone frequency.
5. By pressing a key, for example 5, will generate a
dual tone consisting of 770 Hz for the low group
and 1336 Hz for the high group.
6. DTMF keypads are employed in almost all landline and
mobile handsets. Thus this technology is used in the
telephone switching centers to identify the number dialed
by the caller.
The decoder distinguishes the DTMF tones and produces
the binary sequence equivalent to key pressed in a DTMF
(Dual Tone Multi Frequency) keypad.
The circuit uses M-8870 DTMF decoder IC which decodes
tone generated by the keypad of cell phone.
The signals from the microphone wire are processed by
the DTMF decoder IC which generates an equivalent binary
sequence as a parallel output like Q1, Q2, Q3, and Q4.
