Therefore biological interest in GBR upwelling has been driven by the view that upwelled waters rich in nutrients boost plankton production and overall productivity of the GBR system. We propose to employ a Sensor Network for in situ monitoring of upwellings. Temperature is a good proxy for upwelling however 3D dense spatial data is required to describe upwelling and their impact on plankton abundance. The array of underwater sensors is deployed at various depth on the coral reef in Nelly Bay, Magnetic Island, GBR.. We propose that the temperature data is communicated real time via ad hoc network using RF signal to the on-shore base station. This permits us to collect the plankton data in real-time synchronized to the temperature changes. This paper outlines the methods of the deployment of sensor networks for ecological research.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127722881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Speziale","doi":"10.1109/SENSORCOMM.2007.16","DOIUrl":"https://doi.org/10.1109/SENSORCOMM.2007.16","url":null,"abstract":"The long-term measurement and characterization of acoustic noise spectrum in deep sea is a powerful tool to study the underwater environment and the impact of human activities on the marine ecosystem. Despite sound is extensively used in military and scientific application, there is a lack of measurement of noise level and its variation over long term, in deep sea. This is mainly due to the difficulties in performing long- term accurate wideband measurements in such a hostile environment. Following the scientific and technological success of OvDE, a pilot experimental acoustic station that acquired and transmitted acoustic data from 2000 m depth for 2 years, we propose the realization of innovative deep-sea stations for long- term on-line monitoring of acoustic signals. The innovations of proposed project are summarized in seven key points: 1) pressure resistance up to 350 bar (corresponding to -3500 m depth); 2) capability to operate for more than 5 years; 3) capability to transmit data to shore from distances of about 100 km; 4) sensitivity close to Wenz minimum noise and dynamic range of -120 dB; 5) operational range of frequencies from few Hz to about 80 kHz; 6) capability of point-source identification and tracking; 7) modularity. In order to test and operate these stations the NEMO Collaboration built two scientific infrastructures equipped with shore laboratories and underwater electro-optical cables connecting shore with deep-sea. One is located 25 km SE of the port of Catania (Sicily), already used for OvDE; the other one is located at 3500 m depth 100 km South East of Capo Passero (Siracusa, Sicily), and will be soon operative. These antennas are expected to reach good sensitivity, to allow reconstruction of source position and permit pulse shape study of acoustic signals. These tasks will be fundamental in order to perform studies on sound sources in different research fields: geophysics, acoustical oceanography, bioacoustics, astro-particle physics et cetera.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123959400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we introduced the nickel-chrome alloy as an electrode for our designed microbolometer. To define an electrode on the membrane the etching process is indispensable. Using a dry etching technique there is a selectivity problem with underlayer of nickel-chrome alloy layer during etching process. The other hand there is a topological deterioration, which causes a bad effect for further planarization process when we use wet process. We had fabricated the electrode of microbolometer using hybrid etching technique. Therefore we have successfully established the hybrid etching process for nickel-chrome alloy film which is used for the resistive microbolometer.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129845793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Programming WSNs is a complex task as system level code and application level code are often intertwined. Several programming paradigms have been to date proposed which provide programming abstractions and programming support for the development of WSN applications. In this paper we propose a specification language centered on the concept of lightweight agent based on events and states which distinctively integrates the advantages of three important paradigms and models for WSN programming: agent- based, event-driven and state-based programming. The proposed language is exemplified through a specification of the well-known EnviroTrack application.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125913612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the ANTARES telescope is the detection of high-energy cosmic neutrinos using a 3-dimensional array of 900 photomultipliers distributed in 12 lines. These photomultipliers collect the Cherenkov light induced by the muon produced in the neutrino interaction with the surrounding matter. In order to achieve a good angular resolution, the detector requires a relative time calibration of the order of ~ 0.5 ns. Intending to calibrate the detector at subnanosecond level, a set of pulsed light emitters called Optical Beacons has been designed. They consist of a source of light (LED or laser) with a well- known time emission. The design of these devices and the results obtained with this system will be presented.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"486 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116692600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmission efficiency as low as 47% has been experienced in deployments for various applications. Transmission errors in ESN can be recovered using three basic methods, automatic repeat request, error control coding or hybrid ARQ. This paper presents insights into the choice of error recovery protocols guided by the energy constraints imposed by ESN. We classify the ESN applications into three major classes, which significantly simplifies the choice. Further, we develop an energy model to incorporate the three schemes and draw inferences on the choice based on expected channel conditions and ESN classification. We apply the energy driven choice to two case studies, demonstrating the simplified process of choosing error recovery protocols.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132474607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
