Hi there, my name is Hiruna Vidumina. I am an Electronic and Telecommunication Engineering student at University of Moratuwa. My areas of interest are Telecommunications and Cyber Security, Internet of Things, and Networking.
A vehicle-to-vehicle information sharing method based on DSRC that promotes efficient and safe driving by assisting in lane change and overtaking scenarios, as well as alerting on emergency vehicles and accidents ahead. Communication among vehicles is designed and implemented by establishing a mobile ad hoc network using DSRC-enabled MK5 OBUs. A user-friendly interface is being developed through which drivers can be directly notified of any alert regarding provided functions.
The project is a detailed discussion of the design of a custom processor that was purposely designed for filtering an input image and downsampling the image by a specific factor. Suitable instruction set architectures and micro-instructions were included.
An automatic light and security system was implemented that can automatically switch on a bulb and sound an alarm when someone enters through a door or a gate with the use of motion sensors. Functionality and configurability are improved by introducing several additional features that are available with the use of a remote controller. Designing PCBs and enclosures to meet industrial expectations was highlighted in this project.
An innovative IoT application that classifies the news items received from an external open-source API according to the user’s preferences and sends them to the user’s mobile device using IoT standards, technologies, and tools. The principles related to Node-RED, MQTT, Arduino, and HTML were used here.
A non-recursive, finite-duration impulse response (FIR) bandpass filter was designed according to the prescribed specifications using the windowing method in conjunction with the Kaiser window. The filter was validated by using purposely created three sinusoids.
A high-frequency, two-stage cascaded amplifier was designed and implemented using transistors (without op-amps) that can drive a headphone under the given specifications without causing any distortion to the output signal. This was created to amplify a small signal in the frequency range 20 kHz–200 kHz.
A complete autonomous robot was designed with the use of an ATMEGA32A microcontroller, which tracks the line and avoids walls in the path. All the programming was done with Atmel Studio 7.0.
This is a MATLAB demonstration of how to design, construct, and test the Yagi antenna for the TV reception of a given channel. The action of a folded half-wave dipole with and without the presence of reflectors and directors was modeled.
