Land-cover patterns may serve as significant predictors of sediment discharge. The GSSHA model, a distributed physically-based watershed model, was used for the Todoroki watershed (Ishigaki Island, Okinawa, Japan) to estimate sediment discharge for different land-cover conditions as inferred from Landsat images (1984-2003). Results indicate that over the past 20 years, the changing land cover of the Todoroki watershed, in the direction of increasing sugarcane areas, had enhanced sediment discharge from the watershed. However, landscape patterns exhibited a comparable or even stronger relationship with sediment discharge compared to land-cover percentages. Based on regression analyses, four pattern metrics (number of patches, radius of gyration, splitting, and cohesion) accounted for 99% of the variability of discharged sediment volume (RMSE = 9.6) compared to 89.5% represented by land-cover percentages (RMSE = 31.6). The pattern metrics plus percentages of forest and sugarcane jointly represented almost 100% of the variability (RMSE = 0.0015). Pattern metrics have more predictive capability than land-cover percentages and can improve understanding of watershed sediment discharge process. Copyright © 2012 IAHS Press.

The Philippines is traversed by an average of 20 tropical cyclones annually. This exposes communities to various hydro-meteorological hazards like strong winds, floods, rain-induced landslides, and storm surges. The delivery of relief services is crucial to ensure that affected communities can recover after these hazards. However, this may be hampered by roads that were damaged or deemed impassable in the said events. This study would map the critical facilities (evacuation centers, hospitals, and government buildings) and the road network. It will employ the use of a population density map generated from delineated built-up areas and the projected population estimates based from previous census results to integrate service area capacity of each critical facility. It would then employ a multi-criteria evaluation approach that considers accessibility, service coverage of critical facilities, and possible debris accumulation (ie. vegetation knocked down by strong winds, rubble from flood and storm surges, landslide deposits). Using network analysis in a Geographic Information System, critical and most efficient routes in transporting relief services will be determined. The identified critical path will be prioritized for clearing operations in times of disasters to ensure the effective facilitation of disaster response efforts. The outputs of the study can be used as a basis in improving disaster preparedness and resource prepositioning planning.

In this study, a hydrophobic coating on glass surfaces was fabricated by application of a silicone oil lubricant and activated using a microwave atmospheric plasma jet. Optimization of the treatment was done by variation of the working gas flow rates, input microwave power and plasma treatment time, based on contact angle measurements. In comparison with the untreated glass (37.6°), results show that at best discharge conditions of 600W microwave power, 5/0.5 LPM Ar/N2 flow rate and 10s treatment time, the plasma-treated glass obtained a water contact angle of 105.7°. Surface energy of the glass also decreased from 45.07mN/m for the untreated to 27.97mN/m after plasma treatment. Atomic force microscopy (AFM) and Fourier transform infrared (FTIR) spectroscopy results suggest that increased root-mean-square roughness and introduction of hydrophobic species may have been responsible for the hydrophobicity of the glass surface. © 2014 Elsevier B.V.

The use of a short coaxial plasma line termed the "plasma bulb" has been investigated for enhancement of the wettability of aluminum (Al) and polymethylmethacrylate (PMMA) surfaces. In comparison with other plasma lines, the plasma bulb uses a single magnetron for microwave generation that could produce plasma for surface treatment. For the treatments of Al and PMMA surfaces, various plasma parameters including gas filling pressure, microwave power and treatment time were investigated for different working gases: argon, oxygen and air. Based from contact angle measurements, the largest increase in the wettability of Al (93.8%) and PMMA (76.2%) samples were obtained using air plasma for 5 min and 10 min treatment time, respectively. AFM and EDX results reveal that increased root-mean-square roughness and possible generation of oxygen-containing groups on the surface are the dominant factors contributing to the enhanced wettability. © 2013 Elsevier Ltd.

High dynamic range (HDR) imaging was used to obtain a wide intensity map of a magnetized sheet plasma. A set of 12 low dynamic range (LDR) photographs with various shutter speeds (1/200-1/2 s) was captured with an Olympus FE-19 digital camera. The LDR images were processed to recover color channel response functions of the camera needed to produce RGB radiance maps. The HDR image was finally generated from the combined radiance maps via linear tone mapping. By comparison of histograms, the HDR image uses the whole range of intensity values compared with the underexposed and overexposed LDR images. © 2006 IEEE.
