Abstract Human proximity to water and its dynamics are important understanding the socio-hydrological dilemma between using floodplains avoiding flood risk. However, previous studies have not distinguished of built-up land in (BLF) outside (BLOF). This article provides a new spatiotemporal perspective BLF proximities for changing risk China. The results show that China’s BLFs had an average 5.4...

The world is witnessing a dramatic shift of settlement pattern from rural to urban population, particularly in developing countries. The rapid Addis Ababa urbanization reflects this global phenomenon and the subsequent socio-economic and environmental impacts, are causing massive public uproar and political instability. The objective of this study was to use remotely sensed Landsat data to iden...

As more and more special–purpose database management systems (SPDBMS) are being built, the question how to implement them becomes increasingly important. The SPDBMS CALANDA, which is specialized for the management of time series, is implemented with a new, object-oriented approach which could also be favorably applied to other SPDBMSs. CALANDA consists of an infrastructure layer and a customize...

In this paper, we propose a new multi-layer structural approach for the task of object based image retrieval. In our work we tackle the problem of structural organization of local features. The structural features we propose are nested multi-layered local graphs built upon sets of SURF feature points with Delaunay triangulation. A Bag-of-Visual-Words (BoVW) framework is applied on these graphs,...

An optical fibre sensor for detection of volatile organic compounds (VOCs) has been implemented. This device is based on a vapochromic material presented in the form of bright red powders, which suffers reversible changes in its optical properties when exposed to some organic vapours. The sensor head consists of a nano interferometer doped with the vapochromic material, built onto a cleaved end...

This paper describes how Volunteered Geographic Information (VGI) can support automatic information retrieval (IR) from big remote sensing (RS) data on an example of the Global Human Settlement Layer (GHSL)[1]. Here, the OpenStreetMap 1 (OSM) derived data are used within a satellite imagery processing framework at several stages of an information layer production. Although, we focus on built-up...

We present an experimental investigation of fracture in self-assembled gold nanoparticle mono- and multilayers attached to elastomer substrates and subjected to tensile stress. Imaging the fracture patterns down to the scale of single particles provides detailed information about the crack width distribution and allows us to compare the scaling of the average crack spacing as a function of stra...

the effects of including incoherent (bound-electron) and coherent (rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (e?) range of 40 kev to 3 mev. incoherent scattering decreases the values of these factors in both layers up to e? ~ 200 kev and the effect i...
