Advances in satellite sensors have provided new datasets and though less precise than insitu observations, they can be combined altogether to enhance the prediction of particulate matter. In this article we evaluate a methodology for automatic multi-variate estimation of PM10 dry mass concentrations along with a comparison of three different cokriging estimators, which integrate ground measurements of PM10, satellite MODIS-derived retrievals of aerosols optical thickness and further auxiliary data. Results highlight the need for further improvements and studies. The analysis employs the available data in 2007 over the Emilia Romagna region (Padana Plain, Northern Italy), where stagnant meteorological conditions further urge for a comprehensive air quality monitoring. Qualitative PM10 full maps of Emilia Romagna are then automatically yielded on-line in a dynamic GIS environment for multi-temporal analysis on air quality.","PeriodicalId":288042,"journal":{"name":"2011 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128069418","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}

Stojanovic","doi":"10.1002/ett.2591","DOIUrl":"https://doi.org/10.1002/ett.2591","url":null,"abstract":"We consider a hierarchical underwater acoustic sensor network architecture in which the sensors and the collector stations operate in distinct layers. The hierarchical architecture is motivated by the property of the acoustic underwater transmission medium that for each transmission distance there exists an operating frequency for which the narrow-band signal-to-noise ratio is maximized. The sensors and collector stations are consequently allocated different operating frequencies. We assume a uniform distribution of both sensors and collector stations over the finite area of the sensing field. The sensors are organized into clusters forming virtual transmit/receive arrays. The collector stations on the other hand are equipped with co-located transmit/receive arrays. We adopt a communication theoretic approach and study the interdependence of the sustainable number of hops through the network, end-to-end frame error probability, power and bandwidth allocation. The analysis is performed under the assumption of Ricean fading and interference from other nodes within the same layer of the hierarchy. We present numerical examples that illustrate the network performance and demonstrate that there are preferred operating frequencies which ensure network operation without any cross-interference between the collector network and the sensor network.","PeriodicalId":288042,"journal":{"name":"2011 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"119669127","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 development has been made with the help of supervised machine learning techniques, in a two steps process: firstly, obtaining the conditions that must satisfy the pixels, and secondly, obtaining the features that the image of the skin lesion should have, in relation to the region and the image itself. Tested over a database of 887 images, it has been obtained a results of 89.06% correctly detected. Moreover, as a part of the proposed method itself (derived from the close relationship with the blue-white veil) has been developed a method for obtaining the pixel rules for the dark-red patch of pigment pattern (“a patch of dark red pigmentation”) recognition. Tested over 80 images, it has been obtained a results of 95.14% correctly detected.","PeriodicalId":288042,"journal":{"name":"2011 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120956935","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}
