The analog to digital converters are the key components in modem electronic systems. As the digital signal processing industry grows the ADC design becomes more and more challenging for researchers. Nowadays, ADC becomes ...

Image compression plays a key role in medical image archiving and transfer. Current compression schemes produce high compression rates, if loss of quality is acceptable. However, deficiency in quality cannot be accepted ...

Discovering approximate repeated patterns, or motifs, in genomic sequences is an important problem in computational molecular biology. Motif finding applications arise when identifying shared regulatory signals within DNA ...

Orthogonal Frequency-Division Multiplexing (OFDM) is now regarded as a feasible alternative to the conventional single carrier modulation techniques for high data rate communication systems, mainly because of its inherent ...

In this dissertation work, different types of fair resource scheduling algorithms for OFDMA system have been discussed and their performances are compared with the algorithms for which fairness is no criterion. Time varying ...

The idea of software radio requires an expansion of Digital Signal Processing (DSP) towards the antenna. Hence, for converting the received signal to baseband, the need of efficient high speed digital down converters (DDC) ...

Automatic Question Answering is a type of information retrieval. Given a collection of documents (such as the World Wide Web or a local collection) the system should be able to retrieve answers to questions posed in natural ...

The knowledge of the current location is important for navigation purposes. A person generally understands his/her location by using the knowledge of the surrounding landmarks. In the urban environment, buildings can be ...

Euclidean Distance Transform (EDT) of 2-D and 3-D images is one of the useful tools in various image processing algorithms. It is one of the basic operations in image processing and computer vision fields and essentially ...

Significant advances are being made in the field of biomedicine. The biomedical researchers present their research finally in the form of text. It has become a challenge for biomedical researchers to search for the latest ...
