Discovering and monitoring anuran populations that are in decline, and ascertaining boundaries for cryptic and rare species, is a challenge for their conservation management. Here, we integrate three techniques, bioacoustics ...

Based on a recent molecular phylogenetic study, the South Asian microhylid genus Uperodon (subfamily Microhylinae) currently comprises of 12 valid species that are largely restricted to India and Sri Lanka. Considering ...

Ant colony system (ACS) is a promising approach which has been widely used in problems such as travelling salesman problems (TSP), job shop scheduling problems (JSP) and quadratic assignment problems (QAP). In its original ...

Gesture and speech based Human computer interaction is one of the most natural and convenient way of communication which leads to minimize the gap between human and machine. In this paper, we propose a single HCI ...

In this paper, Braille character recognition in an image of a single side Braille document based on support vector machine (SVM) with Histogram of Oriented Gradient (HOG) as the feature extraction method is discussed. The ...

Accurate measurement of contact angles can define fluid dynamics, surface material properties and contribute to the development of micro/nanofluidic devices. The drop shape analysis technique was developed to accurately ...
