Soil-borne fungal diseases are among the most important factors, limiting the yield of grain legumes in many countries worldwide. Root rot, caused by Aphanomyces euteiches, Rhizoctonia solani, Fusarium solani and wilt, caused by several formae speciales of Fusarium oxysporum are the most destructive soil-borne diseases of pea, chickpea, lentil, fababean and(More)
This research aims to measure the radial artery pulse rate using Piezo film sensor. Being thin and lightweight, Piezo film can be particularly useful for wearable applications. However, it suffers from different kinds of noises. We use EEMD analyzing method to estimate the radial pulse from the noisy data. Although EEMD is considered to be an adaptive(More)
It is difficult for a person who cannot swim to call for help while he face a drowning incident. This make from drowning incidents very dangerous as it can occur silently. In this research we consider the use of wearable sensors to identify victims at early drowning stage. For this we attached a pressure sensor logging unit at the head level of a(More)
1 graduate School interdisciplinary information Studies, the university of tokyo 1 identifying a person facing drowning accident remains challenging even for experienced lifeguards, especially among non-swimmers who tend to be silent when they face such a situation (1). With the recent advancement in electronic and material science, wearable biomedical(More)

We are now witnessing the beginning of Ubiquitous Computing era with the success of several start up to find early adopters among the general public for their home automation solutions through crow funding campaigns. We believe that in the near future, more and more people will come out with new ideas in relation with ubiquitous computing to make our daily(More)
In this work, the definition and design of a specific wave generator concept is offered. The generator aims at providing well referenced T waves for structural health monitoring applications. A distributed network of piezoelectric patches network is considered. Shear effects is the most pertinent effect. An array of 16 piezoelectric stacks is found to be(More)
Manipulation of XML data is becoming increasingly important for multimedia retrieval. Several encouraging attempts at developing methods for searching data have been proposed. However, efficiency and simplicity are still a barrier for further development. This paper gives a global idea about our multimodal system for retrieval multimedia annotated(More)
Recent years witness a phenomenal growth of multimedia data in various modalities, such as image, video, audio, and graphic, which poses a challenge of finding an efficient information retrieval technology. Rather than monotonous, single-modal information, users would like to have a multimodal system to query multimedia documents. In this paper, we present(More)
