Identifying Radiation Absorption and Creating Shadow on the Body of Pigeon Towers in the Villages of Isfahan and Tabriz [PDF]

open access: yesمسکن و محیط روستا, 2021
In most parts of our country, especially the two hot and dry and cold and dry climates, there have been pigeon towers with different shapes and forms for keeping and breeding pigeons. Circular or square in plan, they are made of clay and brick.

Taming 3DGS: High-Quality Radiance Fields with Limited Resources [PDF]

open access: yesACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia
3D Gaussian Splatting (3DGS) has transformed novel-view synthesis with its fast, interpretable, and high-fidelity rendering. However, its resource requirements limit its usability.

PAC-NeRF: Physics Augmented Continuum Neural Radiance Fields for Geometry-Agnostic System Identification [PDF]

open access: yesInternational Conference on Learning Representations, 2023
Existing approaches to system identification (estimating the physical parameters of an object) from videos assume known object geometries. This precludes their applicability in a vast majority of scenes where object geometries are complex or unknown.

Using Ground Targets to Validate S-NPP VIIRS Day-Night Band Calibration

open access: yesRemote Sensing, 2016
In this study, the observations from S-NPP VIIRS Day-Night band (DNB) and Moderate resolution bands (M bands) of Libya 4 and Dome C over the first four years of the mission are used to assess the DNB low gain calibration stability.

Machine learning estimation of tissue optical properties

open access: yesScientific Reports, 2021
Dynamic, in vivo measurement of the optical properties of biological tissues is still an elusive and critically important problem. Here we develop a technique for inverting a Monte Carlo simulation to extract tissue optical properties from the ...
