Figure 1: (a) Our method with 6.7M triangles Rungholt scene. 55K shaded samples. Inset picture was taken through the lens of the Oculus Rift HMD. (b) Naı̈ve ray tracing. 1M shaded samples. Visual quality in our method is equivalent to the one produced by the naı̈ve method when seen through the HMD. (c) Our foveated sampling pattern and k-NN filtering method. Each cell corresponds to a sampling po...

supercells (sigtor), F0-F1 tornadic supercells (weaktor), nontornadic superells (nontor), and a sample of non-supercell discrete storms (number of cases from T02 in parentheses). The shaded boxes represent the middle 50% of the distributions (“box”), and the tops and bottoms of the bars are the 10 and 90 percentiles, respectively (“whiskers”). The horizontal line through each shaded box is the ...

An interactive system for designing curved surfaces is proposed which is based on direct manipulation of a single-view shaded image of this surface. Apart from functions like carving in the surface or adding to it, and local smoothing, sharpening or shifting of selected surface regions, the system supports painting local gradient distributions. An iterative algorithm enforces conservativity of ...

We develop and compare two theories of professional forecasters’ strategic behavior. The first theory, reputational cheap talk, posits that forecasters aim at convincing the market that they are well informed. The market evaluates their forecasting talent on the basis of the forecasts and the realized state. If the market expects the forecasters to report their posterior expectations honestly, ...

Partial shading has a negative impact on the performance parameters of Solar Photovoltaic (PV) array, because it shades certain panels while leaving others un-shaded. This article focuses modeling, comparing and assessment 6×6, 6×5 5×6 size shadowed solar PV arrays under different partial cases in MATLAB/ Simulink software. For this purpose, simulation series-parallel (SP), Total-Cross-Tied (TC...

The possible enhancement of the output from a partially shaded PV array by the use of AC modules has been determined for the PV facade at the University of Northumbria. The system currently has an annual shading loss of about 25% and the study has shown that the use of AC modules would increase the output by approximately 8%. The calculation method is described, and the implications for the des...

Previous studies of object recognition have shown efficient recognition of silhouettes, suggesting that much of the information used to recognize objects resides in the outline. These studies, however, have used objects that contain many components, which provide redundant information. In this study, we examined recognition of silhouettes of less-complex objects, so that redundant information w...

A new instrument called a Multiband Vegetation Imager (MVI) (Kucharik et al., 1997), which uses a 16-bit charge-coupled device (CCD) camera and ®lter exchange mechanism to capture 2-band (visible and near-infrared) image pairs of plant canopies, has been used to measure the light distribution over sunlit leaves and indirectly infer leaf area index (LAI), sunlit LAI and leaf angle distribution (...
