Catchment and riparian degradation has resulted in declining ecosystem health of streams worldwide. With restoration a priority in many regions, there is an increasing interest in the scale at which land use influences stream ecosystem health. Our goal was to use a substantial data set collected as part of a monitoring program (the Southeast Queensland, Australia, Ecological Health Monitoring P...

This article evaluates the potential of 1-m resolution, 128-band hyperspectral imagery for mapping in-stream habitats, depths, and woody debris in thirdto fifth-order streams in the northern Yellowstone region. Maximum likelihood supervised classification using principal component images provided overall classification accuracies for in-stream habitats (glides, riffles, pools, and eddy drop zon...

1. The structure of lotic macroinvertebrate communities may be strongly influenced by land-use practices within catchments. However, the relative magnitude of influence on the benthos may depend upon the spatial arrangement of different land uses in the catchment. 2. We examined the influence of land-cover patterns on in-stream physico-chemical features and macroinvertebrate assemblages in nine...

Oxyfuel combustion is a promising technology to produce CO2 rich effluents. Nevertheless, storage as well valorization steps require increase the purity of these effluents due presence CO and NOx produced during process. In view development transition metal-based catalyst for this application, cobalt and/or copper derived hydrotalcite materials were used precursor oxide NO-CO abatement in gas s...

the objective of this study was to diagnose integrative ecological health of an urban stream,which is located in the asian temperate region. the research approach was primarily based on the index ofbiological integrity (ibi) using fish assemblage and a qualitative habitat evaluation index (qhei). and these indexes were compared with long-term conventional chemical dataset during 1996-2005. for ...

soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...

The rising demand of mixed reality postproduction requires an exact reconstruction of the camera parameters during the shoot for correlating the view of a virtual camera with a real one. This paper describes a tool for determining the parameters of the real camera view, image-based. During postproduction selected reference points are tracked on the video stream, the relative geometrical relatio...

This paper proposes a fuzzy logic control based dynamic channel allocation (DCA) to ECMA-368 based WiMedia UWB networks, which aims to support mixed high-quality video traffic and shipboard control data traffic with high reliability and priority as well. The DCA method applied in this paper is to flexibly vary the portions of time slots of either the prioritized contention access (PCA) or the d...

The paper presents a chaos-based True Random Number Generator (TRNG) implemented in commercially available mixed-signal PSoC reconfigurable devices without any external components. Contrary to the traditionally used sources of randomness (eg various ”well-behaved” analog noise sources) it uses well-defined deterministic analog circuit that exhibits chaos. A new simple method of mapping the dete...
