Shallow parsing of Gujarati text
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Shallow parsing is the process of assigning tag to minimal, non recursive phrase
of the sentence. It is useful for many applications like question answering system,
information retrieval where there is no need of full ...
Study of the effectiveness of various low power techniques on sequential and combinational gate dominated designs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
In last decade, the technological advancement is seen in semiconductor field like never
before. The need for low power has caused a major paradigm shift where power dissipation
has become as important consideration as ...
Use of collaborative filtering for targeted advertising
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Often in our daily life, we come across situations when we have many options available and are expected to choose one of them. May it be a bookstore, CD shop or a shopping store, even on the internet, the availability of ...
Wireless LAN 802.11 security using elliptic curve cryptography
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
IEEE 802.11 is a standard defines the specification of Wireless Local Area Network (WLAN), came into existence in 1997. As communication medium is wireless, security is a major concern to protect the data from adversary. ...
Fingerprint image preprocessing for robust recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Fingerprint is the oldest and most widely used form of biometric identification. Since they are
mainly used in forensic science, accuracy in the fingerprint identification is highly important.
This accuracy is dependent ...
Architecture design for preliminary ECG analysis system using new DFT based analysis technique
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis proposes a hardware architecture of an ASIC for a portable ECG analysis system. The device is meant to record and analyze ECG signals in real time so as to detect the presence of abnormalities. In order to ...
Data blocking for partitioned data
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
Since last few years the data consumed and produced by various applications is increasing
tremendously. This thesis aims to achieve faster query processing for this data. The overall work
of the thesis is divided into ...
Object classification in images using information slicing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Human visual system, in real world, identifies objects by their shapes, sizes and colors. More than often we identify objects around us specifically by using contextual knowledge of the objects. For example, an area of ...
High-speed 512-point FFT single-chip processor architecture
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis present a fully parallel novel fixed point 16-bit word width 512 point FFT processor architecture. The 512 point FFT is realized by decomposing it into three 8 point FFT units. This approach reduces the number ...
Single frame superresolution
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Super-resolving an image from single frame observation image. In many cases more than one low resolution observations may not be available, need high spatial resolution images e.g. medical imaging, remote sensing etc.. We ...
