Objectives. Assessment of left ventricular (LV) systolic function in patients with atrial fibrillation can be difficult. Acoustic cardiography provides several parameters for quantifying LV systolic function. We evaluated the ability of acoustic cardiography to detect LV systolic dysfunction in patients with and without atrial fibrillation. Design. We studied 194 patients who underwent acoustic...

GeoWeb2.0 is the geographic embodiment of O’Reilly’s ideas and it is increasingly becoming a trend method to construct a GIS application. Spatial Data Infrastructure (SDI) is really GeoWeb applications. In the quest to establish the GeoWeb2.0, a free version of rich spatial Flex Viewer has been released by Environmental Systems Research Institute, Inc (ESRI). While the remote sensing satellite ...

Awareness of the importance of spatial data in achieving development strategies is high in Rwanda. Government and non-governmental institutions are aspiring to use Geographic Information Technologies (GITs) in their day-to-day activities. The non-existence of a National Spatial Data Infrastructure (NSDI) in Rwanda brings to light serious issues for consideration. Still lacking is a spatial data...

We propose an automatic algorithm, named SDI, for the segmentation of skin lesions in dermoscopic images, articulated into three main steps: selection of the image ROI, selection of the segmentation band, and segmentation. We present extensive experimental results achieved by the SDI algorithm on the lesion segmentation dataset made available for the ISIC 2017 challenge on Skin Lesion Analysis ...

In order to forecast the geological disaster, a forecasting model of geological disasters in Hefei area has been established. The model is based on raster data model. Because that the data from local SDI are vector data, some pretreatment must be done before they are used in the forecasting model. Some data, such as geological data, meteorological data and precipitation, has been translated int...

This research project was one of a number concerned with mechanized information retrieval carried out at INSPEC and supported by grants from, originally, the Department of Education and Science's Office for Scientific and Technical Information (OSTI) and, later, the British Library Research and Development Department (BLRDD). The first project, in the period 1967-69, had investigated the perfor...

Metadata are "data about data", that is to say, they describe the content, quality, condition, and other characteristics of data in order to help a person to locate and understand data. Nevertheless, maybe one of the main problems for launching a Spatial Data Infrastructure (SDI) is to have appropriate and well-defined contents for its catalogues, that is to say metadata. The creation of metada...

Technological development and increasing awareness of geodata and its use has caused an explosion of digital content. However, this was not accompanied by dissemination and accessibility measures. Spatial Data Infrastructures (SDIs), allowing extensive reuse of geoinformation, may offer a solution. SDIs face organisational, technological, legal, cultural and linguistic challenges. The enrichmen...
