Garbage in and garbage out. A Q&A system must receive a well formulated question that matches the user’s intent or she has no chance to receive satisfactory answers. In this paper, we propose a keywords to questions (K2Q) system to assist a user to articulate and refine questions. K2Q generates candidate questions and refinement words from a set of input keywords. After specifying some initial ...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

The natural fiber reinforced composites have the advantage of being light weight, renewable, bio-degradable, cheap and eco-friendly. So there is every need to investigate potentiality of natural fibers and its composites, which can be used in highly demanding situations. However, very small contribution of research work exists in the design and fabrication of composite materials using natural f...

Iridescent colors appearing on natural objects, such as the feathers of a hummingbird, surfaces inside seashells, and shells of beetles, are beautiful and impressive. The cause of such iridescent colors is interference of light inside multilayer film structures covering the natural objects. This paper proposes a method for realistically rendering iridescent colors appearing on natural surfaces,...
