Birds have been widely used as biological indicators for ecological research. They respond quickly to environmental changes and can be used to infer about other organisms (e.g., insects they feed on). Traditional methods for collecting data about birds involves costly human effort. A promising alternative is acoustic monitoring. There are many advantages to… (More)
It is a significant challenge to detect a transparent object using conventional visual sensors. In this paper, we show that the characteristics of transparent objects under different lighting conditions (normal light and laser light) can be exploited for improved detection accuracy. The authors analyzed the object characteristics and found a novel method… (More)
The Ninth Annual Machine Learning for Signal Processing (MLSP) Data Competition Committee has hosted a bird classification challenge at Kaggle.com (http://www.kaggle.com/c/mlsp-2013-birds). For this year's competition, participants were asked to develop classification algorithms to reliably identify the set of bird species in real-world audio data collected… (More)
Recent evidence suggests that nitric oxide (NO) signaling plays an important role in plant–pathogen interactions and that aconitase is a major target of NO. In the present study on the signaling role of NO in the elicitation of defense responses in peach fruit against Monilinia fructicola and subsequent effect on brown rot disease, 15 μM NO solution induced… (More)
This paper proposes virtualized WiFi network that can dynamically create a virtual Base Station (vBS) around the target mobile devices that offers dedicated base station resources for satisfying service-specific QoS and works as a gateway for a corresponding virtual network or slice. Specifically, the paper proposes (1) a technique to dynamically configure… (More)
Four new triterpene glycosides were isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). They were designated as squarroside I, being a cycloartane-type glycoside, and squarrosides II, III and IV, being oleanene-type glycosides. Their structures were established by using two dimensional (2D) NMR techniques.
