Acoustic-to-articulatory inversion: speech quality assessment and smoothness constraint
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)The ability of humans to speak effortlessly, require coordinated movements of various articulators, muscles, etc. This effortless movement contributes towards naturalness, intelligibility and speaker identity in human ... -
Active contours in action
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)There was considerable success in converting images into something like line drawings without resorting to any but the most general prior knowledge about smoothness and continuity. That led to the problem of “grouping” ... -
Active sub-harmonic mixer
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)A superheterodyne receiver is commonly used receiver, but its main problem is its large size. To increase the integration and reduce the size of the receiver, the concept of direct conversion receiver came in the picture. ... -
Acyclic edge coloring of complete r-partite graphs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)An acyclic edge coloring of a graph G is a proper edge coloring of G which has no dichromatic cycle. The minimum number of colors required to acyclically edge color graph G is called its acyclic chromatic index, denoted ... -
Acyclic edge colouring of subgraphs of hypercubes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2020)Acyclic edge colouring is a very important combinatorial optimization problem, which many researchers are currently working on. Acyclic edge colouring is assignment of colours to vertices or edges of the graph such that, ... -
Adaptive analog line driver using digital tuning
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Transmission lines are widely used for transmitting electrical signals.
