The technique of DGT (diffusive gradients in thin films) was applied to obtain high-resolution vertical profiles of dissolved reactive phosphorus (DRP) in sediment porewater of Lake Chaohu, a shallow eutrophication lake. Three kinds of DGT probes (with three thicknesses of diffusive gel: 0.38 mm, 0.78 mm and 1.18 mm) measured vertical concentration and induced flux from solid to solution phase ...

The increasing availability of high resolution airborne imagery increases the accuracy of building modelling of urban scenes. This high accuracy of building modelling offers a strong reference for disaster recovery and asset evaluation. With the advantage of having more façade information, this thesis builds on previous efforts in building reconstruction from airborne oblique imagery. Based on ...

The Sangan processing plant consists of four consecutive low-intensity magnetic separation steps with the same magnetic field intensity of 1300 Gauss for upgradation of iron ore. Hence, the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation, and proceed to the tailing dam. Flotation is a powerful technique for upgradation...

Remotely sensed imagery provides a useful tool for land managers to assess the extent and severity of post-wildfire salvage logging disturbance. This investigation uses high resolution QuickBird and National Agricultural Imagery Program (NAIP) imagery to map soil exposure after ground-based salvage operations. Three wildfires with varying post-fire salvage activities and variable ground truth d...

The hidden terminal is classified as the sending hidden terminal and receiving hidden terminal in this paper. The quantitive analysis of hidden terminal problem and simulation-based analysis of its mechanism is discussed. Through the extensive ns2 simulations the detail comparison for the impact of sending hidden terminal and receiving hidden terminal to the performance of TCP is also given. Th...

In this paper we study a realistic setup for phase retrieval, where the signal of interest is modulated or masked and then for each modulation or mask a diffraction pattern is collected, producing a coded diffraction pattern (CDP) [CLM13]. We are interested in the setup where the resolution of the collected CDP is limited by the Fraunhofer diffraction limit of the imaging system. We investigate...

A scanning magnetoresistive (MR) microscope is developed for high-resolution imaging of magnetic tapes and digital media. Second-harmonic detection is used to remove thermal anomalies. We are able to image sufficient lengths of tape for authentication purposes and for data recovery from damaged samples. The second-harmonic technique provides high-contrast magnetic images of the magnetic storage...

In the emergence situation after a large earthquake, fast evaluation of the damage is really necessary for rescue team and recovery plan, even if it is quite rough. Remote sensing image provides a new information source for rapid estimation of earthquake damage. In the recent years, achievements on identifying seriously damaged area by remote sensing are reported, some of them are from high res...

Super-resolution microscopy with phase masks is a promising technique for 3D imaging and tracking. Due to the complexity of the resultant point spread functions, generalized recovery algorithms are still missing. We introduce a 3D super-resolution recovery algorithm that works for a variety of phase masks generating 3D point spread functions. A fast deconvolution process generates initial guess...

We report a fully integrated serial-link receiver with optical interface fabricated with a 0.18 mm complementary metal oxide semiconductor technology for long-haul display interconnects. The receiver includes a trans-impedance amplifier, a limiting amplifier, a clock and data recovery circuit, 1:64 de-multiplexer and a built-in error checker. The receiver produces 64-bit wide electrical signals...
