Design and layout of single bit per stage pipelined ADC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
The concept of pipe-lining, often used in digital circuits, can also be applied in the analog domain. It helps to achieve higher speed where several operations must be performed serially. In this work, pipe-lining is ...
Image ranking based on clustering
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted
by feature similarities with respect to the query. However, images with high feature similarities to the query may be very ...
Low noise amplifier design at 2 GHz
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Low Noise Amplifier (LNA) is one of the most important building blocks of any wireless
receiver. In this an attempt has been made to study two types of LNA designs. The first
design is the conventional which consists of ...
Migration of database from one cloud to other clouds
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
On demand services and scalability features of cloud computing has attracted many customers to move their applications into cloud. Cloud service providers are following di erent standards to host applications and data. ...
Part of speech tagging for Gujarati text
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Part-of-speech (POS) tagging is a process of assigning the lexicon category to each
lexicons in a given natural language sentence, that best suits the definition of the lexicon as well as the context of the sentence in ...
Person recognition from their hum
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In this thesis, design of person recognition system based on person's hum is presented. As hum is nasalized sound and LP (Linear Predication) model does not characterize nasal sounds sufficiently, our approach in this work ...
Performance evaluation of kerberos cross-realm authentication using SIMNET
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Today, the network is being implemented in such a manner that consist of geographi-
cally diverse clients and distributed as well as centralized servers. To prevent unauthorized access to system resources such as servers, ...
Practical approach for depth estimation and image restoration using defocus cue
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Reconstruction of depth from 2D images is an important research issue in computer vision. Depth from defocus (DFD) technique uses space varying blurring of an image as a cue in reconstructing the 3D structure of a scene. ...
Prolog based approach to reasoning about dynamic hierarchical key assignment schemes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
The problem of allowing the higher level users access the information related to lower level is called Hierarchical Access Control Problem. In a hierarchical access control system, users are partitioned into a number of ...
Single ended sense amplifier for DRAM
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Today design of eDRAM is facing more challenges as the technology node is scaling
down every year. Supply Voltage is also scaling down in accordance with the technology. Thus, charge on the bitlines, to sense is also ...
