This paper provides a brief survey of document structural similarity algorithms, including the optimal Tree Edit Distance algorithm and various approximation algorithms. The approximation algorithms include the simple weighted tag similarity algorithm, Fourier transforms of the structure, and a new application of the shingle technique to structural similarity. We show three surprising results. ...

Field studies were conducted on several attic assemblies having stone-coated metal shake roofs with and without infrared blocking color pigments (IrBCPs) and with and without above-sheathing ventilation. The combination of increased solar reflectance and above-sheathing ventilation reduced the heat flow penetrating the attic floor by 70% as compared with the heat flow penetrating the attic floo...

—— The subject of this project is two-dimensional signal processing —— the joint processing of multiple readback waveforms from neighboring tracks so as to recover the recorded user bits. Two-dimensional signal processing promises significant increases in areal density, in part because it facilitates the elimination of guard band inefficiencies, in part because it enables shingle writing strate...

Due to decreases in the availability and quality of traditional water resources, harvested rainwater is increasingly used for potable and non-potable purposes. In this study, we examined the effect of conventional roofing materials (i.e., asphalt fiberglass shingle, Galvalume(®) metal, and concrete tile) and alternative roofing materials (i.e., cool and green) on the quality of harvested rainwa...

This work shows the first demonstration of thermal laser separation (TLS) and post-metallization passivated edge technology (PET) applied to tunnel-oxide contact (TOPCon) shingle solar cells. The cells with 26.46 mm × 158.75 size are separated from industrial full-square TOPCon host singulation is performed either by TLS front side (emitter side) or conventional scribe mechanical cleaving (LSMC...
