BRIEF DESCRIPTION OF PROJECTS UNDERTAKEN:
Project A: Hardware Implementation of Development of Teacher Student Interaction System using RFID
and XBEE.
Based on analysis of features of Zigbee Wireless sensor networks and Radio Frequency Identification
(RFID) technology, we implemented a protocol stack of Zigbee using method of module dividing. From the
perspective of improving teaching methods, combining teaching practices, a teacher-student interaction system
based on Zigbee and RFID technology was designed and implemented for the application of actual teaching.
Circuit Diagram at Student System: The main part of the student’s system is the ARM7 LPC 2148
Microcontroller which acts as the heart of the system which controls every part of the system. The Microcontroller
can be interfaced with many peripherals some of them are LCD, RFID and XBEE. The power supply for this is been
provided by the linear mode power supply the Microcontroller and XBEE needs 3.3v, RFID reader needs 5v and
they are supplied according to their requirements. Coming to the working process of the system when the student
enters the class room then he/she places the RFID tag across the RFID reader which will be placed at the entrance
of the class room then the information present in the RFID tag will be collected by the RFID reader the information
EDUCATION and
will be in the form of TTL logic so to convert it into the serial form we use MAX232 which converts serial data into
TTL and vice versa. Then the serial data has been transferred the Microcontroller through RS232 again the serial
data will be converted into TTL logic by using MAX232, from the Microcontroller the data will be transfers to the
XBEE- A Zigbee protocol which is used to transfer the data from the student system to the teacher’s subsystem
through wireless technology.
Circuit Diagram at Teacher Subsystem: The received information from the XBEE from student’s subsystem will
the converted in the serial data to transfer it to the teacher’s computer, at teacher’s computer the details of the
attendance list will be displayed in the respective files. If the teacher wants to convey any information to the
students, the teacher enters the information at the computer the same reverse process occurs and the data entered
at the teacher’s subsystem will be displayed on the LCD which has been interfaced with the Microcontroller.
Project B: Project Hardware Implementation of Pitch Tracking Algorithms for Carnatic Musical Notes along
with Blind Source Separation Algorithm and Modeling of Computerized Carnatic Musical Notes and
Gamakas.
We describe algorithms for identifying base sadja (C4 in western music) and melakarta raga
identification, modelling and synthesis of gamakas in Carnatic music. Input to our algorithm is the linear
instantaneous mixture of tanpura and other instrument (i.e., guitar, violin etc) signals. We use blind source
separation (BSS) algorithm to separate tanpura signal and other instrument signal followed by pitch estimation
using harmonic product spectrum (HPS) algorithm. Cluster the pitch values of tanpura signal into 3 clusters and
the minimum value in a cluster corresponds to base sadja because tanpura uses only three notes base sadja,
panchama (G4 in western music) and upper Octave sadja(C5 in western music). Cluster pitch values of other
instrument signal in base octave into 8 clusters then create normalized relative frequency ratios of pitch values and
compare with 72 melakarta ragas database. The best match corresponds to the melakarta raga. In modelling of
gamakas, first obtain the pitch trajectory of music signal using HPS algorithm followed by modelling of pitch
trajectory using iterative prefiltering (IPF) and lattice filters. Synthesis is performed using additive synthesis
process which uses modelled pitch trajectory,amplitude and phase information.
