Impacts of Possible CO2 Seepage from Sub-Seabed Storage on Trace Elements Mobility and Bacterial Distribution at Sediment-Water Interface
Abstract A potential CO2 seepage from sub-seabed storage may cause cascade effects in marine ecosystems if it influences a process that has a key-function in the complex ecosystem. Therefore not only the primary effects (CO2 increase and pH...

Characterization of two novel low frequency microphones for photoacoustic gas sensors
Abstract The photoacoustic principle for measuring gas concentration is well established based upon macromechanical assembly. However, microsystem based photoacoustic could benefit from smaller size and lower cost, but needs a high resolution...

Microstructural analysis of a subhorizontal gold-quartz vein deposit at Donalda, Abitibi greenstone belt, Canada: Implications for hydrodynamic regime and fluid-structural relationship
Abstract The Donalda gold deposit in the southern part of the Archean Abitibi greenstone belt consists mainly of a subhorizontal gold-quartz vein perpendicular to subvertical shear zones. The 0.3–0.5 m thick vein is characterized by vein-parallel...

The thermo-electric effect of magnetite and the mechanism of geo-electric abnormalities during earthquakes
Abstract The thermo-electric coefficients of twenty-six magnetite samples, formed either by magmatism or metamorphism, were tested by the thermo-electric instrument BHET –06. Results showed that the coefficient is of a constant value of about...

Reprint of: CAA boundary conditions for airfoil noise due to high-frequency gusts
Abstract This paper proposes inflow and outflow boundary conditions for direct computation of airfoil noise under the influence of impinging gusts with a particular interest in the high frequency response. The proposed boundary conditions are based...

Regional Rainfall Frequency Analysis for the Luanhe Basin – by Using L-moments and Cluster Techniques
Abstract Flood frequency analysis is essentially a problem of information scarcity in arid and semi-arid regions. Practically in these regions, the length of records is usually too short to insure reliable quantile estimates. The density of rainfall ...

A quality-guided displacement tracking algorithm for ultrasonic elasticity imaging
Abstract Displacement estimation is a key step in the evaluation of tissue elasticity by quasistatic strain imaging. An efficient approach may incorporate a tracking strategy whereby each estimate is initially obtained from its neighbours’...

Automated object-based classification of topography from SRTM data
Abstract We introduce an object-based method to automatically classify topography from SRTM data. The new method relies on the concept of decomposing land-surface complexity into more homogeneous domains. An elevation layer is automatically...

Discussion on Parameter Choice for Managing Water Quality of the Drinking Water Source
Abstract With the increasingly degraded water environment, some substances will gradually accumulate in our drinking water source—the surface water, and finally threaten drinking water safety when their contents reach a certain amount. To give early ...

Increasing the spatial resolution of thermal infrared images using cokriging
Abstract Thermal infrared (TIR) satellite images are of great interest in many remote sensing applications. However, owing to well-known physical reasons and technical limitations, the TIR band has a spatial resolution that is coarser than the other ...

Evaluating land use/cover change with temporal satellite data and information systems
Abstract Rapid changes in land use land cover (LULC) adversely affect the environment. In order to provide information for policymakers to support sustainable development, detailed data about these regions is urgently needed. Use of remote sensing...
