Low power and high performance devices are in demand for today’s microelectronics market. Conventional planar CMOS transistors on bulk silicon substrate have been a key component in ultralarge- scale integration technology ...

Surface acoustic wave (SAW) devices are widely used in sensors, actuators, filters, and telecommunication systems. SAWs are elastic waves launched on a piezoelectric substrate when an electrical signal is applied to metallic ...

Image fusion is a technique to assimilate information acquired from similar or dissimilar sources of images. Compared to the source images, fused images convey more information, and they have more clarity. However, distorted ...

This research primarily deals with the problem of ow division in the context of emerging multihomed protocols like the Stream Control Transmission Protocol (SCTP). In this work we augment SCTP to increase its throughput ...

This thesis documents our investigations on processing of multichannel electrocardiogram signals using multiscale principal component analysis (MSPCA). There are three broad contributions. First, wavelet based denoising ...

The median filter is a nonlinear filter that outputs the median of the data inside a moving window of predetermined length and has been traditionally used to remove impulse noise from images. The filter is known for its ...

The notion of coded caching for the content distribution networks was introduced by Maddah-Ali and Niesen. We looked into several aspects of optimal coded caching schemes as part of my doctoral thesis. We studied the ...

This thesis aims towards the development of an objective method for the assessment of hypernasality in cleft palate speech based on the spectral analysis of speech. The proposed method is based on the detection and severity ...

Skin detection is an important step in various image processing and vision-based Human-Computer Interaction (HCI) applications. It is the process of finding skin-coloured pixels and regions in an image or a video. The major ...

In this thesis, we propose a number of online signature verification systems, in line with DTW based approach. We see that such systems in literature perform a temporal alignment between the feature vectors that are derived ...
