Sensor networks for the natural environment require an understanding of earth science, combined with sensor, communications and computer technology.We discuss evolution from data logging to sensor networks, describe our research a glacial highlight future challenges in this field.
A sensor network is described which obtains data from nodes on and inside glaciers. Power management through scheduling selective control used to allow a lifetime of at least one year batteries. Radio links in the glacier across 2.5 km distances are for commands. The prototype system was installed Norway 2003 this paper describes details full design 2004 discussion lessons learnt.
This paper describes a decade of work on digital imaging for museums. From 1989 to 1992, the visual arts system archiving and retrieval images (VASARI) project produced digital-imaging that made color-calibrated up 20000/spl times/20000 pixels directly from paintings. It used seven color-separation bands in visible region, resulting an average color error around 1 /spl Delta/E*/sub ab/ unit. These have since been monitor condition paintings, document paintings during conservation treatment,...
This paper discusses the interim results of AHRC RTISAD project. The project has developed and tested a range techniques for gathering processing reflectance transformation imaging (RTI) data. It also assembled detailed understanding breadth RTI practice. Over past decade applications algorithms in broad domain increased markedly, with current working addressing issues such as large resolution capture, 3D RTI, annotation, enhancement amongst others. Capture datasets begun to occur all...
Abstract The Internet of Things is a term which has emerged to describe the increase connectivity everyday objects. While wireless sensor networks have developed highly energy efficient designs they need step change in their interoperability and usability become essential tools study our environment. This paper shows how (IoT) can be seen as natural evolution environmental sensing systems. We discuss different styles examples IoT systems illustrate key technical challenges ahead. future...
This paper describes the VIPS image processing library and user-interface. is used in many museums galleries Europe, America Australia for capture, analysis output. popular because it free, cross-platform, fast, can manage images of unlimited size. It also has good support color, an important feature this sector. Its architecture will be illustrated through examples its use a range museum-driven applications. free software distributed under LGPL license.
This paper reports on the development of a utility-based mechanism for managing sensing and communication in cooperative multi-sensor networks. The specific application considered is that GLACSWEB, deployed system uses battery-powered sensors to collect environmental data related glaciers which it transmits back base station so can be made available world-wide researchers. In this context, we first develop protocol each sensor locally adjusts its rate based value believes will observe. Then,...
Sensing devices are increasingly being deployed to monitor the physical world around us. One class of application for which sensor data is pertinent environmental decision support systems, e.g., flood emergency response. For these applications, readings need be put in context by integrating them with other sources about surrounding environment. Traditional systems predicting and detecting floods rely on methods that significant human resources. In this paper we describe a semantic web...
There has been increased concern over health effects related to potential exposure of building occupants bioaerosols. We report the case a worker with respiratory illness bioaerosol in water-damaged extensive fungal contamination. performed environmental tests evaluate fungi, and we used mycotoxin-specific IgG antibody serologic studies attempt mycotoxins. Extensive contamination was documented many areas building. Penicillium, Aspergillus, Stachybotrys species were most predominant fungi...
With the aim of providing a digital electronic replacement for conventional photography paintings, scanner has been constructed based on 3000 X 2300 pel resolution camera which is moved precisely over 1 meter square area. Successive patches are assembled to form mosaic covers whole area at c. 20 pels/mm resolution, sufficient resolve surface textures, particularly craquelure. To provide high color accuracy, set seven broad-band interference filters used cover visible spectrum. A calibration...
A wireless sensor network has been designed and deployed to gather data from nodes inside glaciers. This paper describes the solutions power management, radio communications other challenges faced in system together with a discussion of performance final system. 18 months have now received, which provide an insight not only into glacier's behaviour but also design decisions. The uses custom PIC-based ARM-based base station controls weather differential GPS. Different versions installed...
At a first glance there might appear to be an obvious alignment and overlap between the approaches prescribed by REST Linked Data. On more detailed inspection divergences in scope applicability present themselves, for some aspects, incompatibility. In this paper we investigate these similarities differences suggest coupling is worthy of third look: combination as flexible environment which developer can focus on domain driven applications.
Abstract We reconstruct englacial and subglacial drainage at Skálafellsjökull, Iceland, using ground penetrating radar (GPR) common offset surveys, borehole studies Glacsweb probe data. find that water is not stored within the glacier (water content ~0–0.3%). Instead, mostly impermeable meltwater able to pass quickly through main body of via crevasses moulins. Once bed, a thin (1 m) layer debris‐rich basal ice (2% content) till. The hydraulic potential mapped across survey area indicates...
Abstract Fluctuations in glacier motion are very common and thought to be controlled by subglacial hydrology till deformation. There few instrumented studies that have monitored seasonal changes. We use the innovative Glacsweb situ wireless probes, combined with dGPS custom geophone data from an Icelandic soft-bedded temperate glacier, show there two distinct styles of speed-up events. Relatively small diurnal events occur during melt season, whilst winter larger multi-day related positive...
Durante el proceso de la investigación policial, resulta esencial comprender delito y interacción del perpetrador con víctima escena crimen.
