Design Of An In-Pipe Reliable Leakage Detector
* Introduction
[CE 1.1]
- Project: Design of In-Pipe Reliable Leakage Detector
- Duration: [Date] – [Date]
- Location: Deakin University, Australia
- Position: Electrical Engineering Student
* Background
[CE 1.2]
A significant amount is lost due to pipe faults and leaks in most water distribution systems. Due to this reason, the leak identification is adequate for water resources optimization and rationalization. Thus, the methodologies and techniques which are presently utilized for the leaks individuation, despite the fact consider universally accepted phenomena based on techniques which are currently accepted.
These are time-consuming and main need highly experienced personnel. Furthermore, the methods become ineffective and unreliable when used to measure under the pipe’s specified operational conditions. Thus, the work was done on a wireless sensor network to detect and locate the issue.
[CE 1.3]
The project’s aim consisted of two units that were placed in a specific difference. I worked on setting the sensor output, which remained the same despite no leakage. In case of any difference, it resulted in pipeline leakage, and it was sent to PC from ZIGBEE, followed by closing the source valve with DC motor assistance. I controlled the motor using the relay.

The work activities were predefined in the project, and various scenarios were analyzed mainly to get the targeted work results and achieve the specified results within the defined work tenure. I accomplished all the related project duties with the assistance of the project guide.
[CE 1.5]
Responsibilities:
- I applied Electrical Engineering expertise to the water flow sensor, the amplifier output, and the microcontroller.
- I executed the signal conditioning unit, which assisted well in accepting input signals from the analogue sensors.
- I connected a microcontroller transmitter pin to the circuit, mainly to convert a 5V input to RS232 level.
- I utilized a diode rectifier, which assisted in providing a full-wave rectified voltage, mainly resulting in filtering from a simple capacitor filter for DC voltage production.

- Title: Multi-way Relay Networks
- Duration: [Date] – [Date]
- Location: Deakin University, Australia
- Position: Electrical Engineering Student
* Background
[CE 2.2]
Multiple users simultaneously work to transmit data via relays in multi-way relay networks. The relay mainly communicates bi-directionally among different users in pairwise transmission. There is an SNR (signal-to-noise ratio) penalty without the proper synchronization.
[CE 2.3]
The project scope was to conduct an error performance investigation of data transmission among users, focusing on symbol misalignment and phase offset. I applied the knowledge to design appropriate algorithms to improve performance and investigated errors in the multi-way network.
It was of greater significance for data transmission, improving performance and reducing errors. Relevant research was conducted throughout the project’s tenure to achieve the targeted project results.
[CE 2.4]
The work nature was carrying out an error-performance investigation of a multi-way relay network for users’ signals when a phase offset was present. I conducted an error-performance investigation of a multi-relay network when a user’s signal symbol was misaligned.
[CE 2.5]
My technical responsibilities were:
- I initialized the work activities with phase offset values variations and mainly noted the considered case results.
- I implemented signal decoding at the user end, resulting in the maximum likelihood criterion.
- I worked on researching the utilization of the user’s signal, mainly for the extraction of the message with own signal subtraction.
- I worked on plotting the graph using a specified probability function, which was linked to one error in the SNR ratio, mainly using engineering skills.

[CE 3.2]
The conceptual work is mainly for maintaining time management and carrying out proper scheduling activities. There is a requirement to implement an effective and low-cost automation system. In recent times, the systems developed have mainly been for counting and manual systems.

The project goal was to develop a count system utilizing GSM and RFID technology. I selected RFID technology, which was an emerging technology mainly utilized in various applications. I typically performed object identification using RFID technology, which consisted primarily of an RFID reader and an RFID tag.
I utilized RFID tags in the RFIS system, mainly interrogated by the RFID reader. The work’s primary goal was to identify data in electromagnetic fields automatically. I used the smaller, inexpensive RFID tags, which were powered by an RFID reader from the small signal they produced.

- I mainly used the RFID reader for interrogating RFID tags.
- I worked on setting up an antenna with the reader for radio-wave emission, and the tag responded well by sending the data back. Acquire no-cost CDR samples from AustraliaCDRHelp.Com.
