Design of optically actuated MEMS based optical switch using bragg grating
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Although optical communication networks are successful in providing reasonable amount of speed for communication, these networks are still facing an issue of electrical to optical and optical to electrical overhead while ...
Design of syllable-based speech segmentation methods for text-to-speech (TTS) synthesis system for Gujarati
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Text-to-speech (TTS) synthesizer has been proved to be an aiding tool for many visually challenged people for reading through hearing feedback. Although there are TTS synthesizers available in English and other languages ...
Development of verification environment for multiply-accumulate unit using system verilog
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Nowadays, Application Specific Integrated Circuit (ASIC) design are becoming complex, even designs based of Field Programmable Gate Array (FPGA) are also complex. So it is very difficult to verify the design through waveform ...
Exploring suitable classifier for robust face and facial expression recognition.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Face recognition by machines has been studied since last few decades and the problem is attempted to be solved by various ways. However any robust solution is not acheived yet by the researchers due to numerous challenges ...
Financial time series analysis and prediction using Chaos theory, HHT and SVR.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Stock market prediction is a very complex and therefore well studied area of economics and applied mathematics. The stock market prediction is often termed as a non-solvable problem precisely because as cited many times ...
FIR filter for high speed 60 GHz wireless communications.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis report the design and implementation of the FIR filter at 5 GS/s presented. IEEE 802.15.3c standard declared unlicensed band from 57 to 66 GHz. This 60 GHz wireless communication transmitter uses interpolator ...
Indoor target tracking using wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis, we consider indoor target tracking using wireless sensor networks (WSNs). In outdoor environment, target tracking can be done using Global Positioning Systems (GPS). But in the indoor environment this option ...
Improved authentication packet marketing for IP trace-back
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
IP Trace back is a significant technique for countering Denial of service attacks; it deals with the problem of finding the true source of packets, which takes part in a flooding based Denial of Service attack. Finding the ...
