Dipole Diffusion Error in Thin Geometry: Optical Thickness Laws for Grid-Free Subsurface Scattering
Faruk Alpay, Baris Basaran
The dipole and its descendants model subsurface scattering with a radial reflectance profile fitted to a flat, semi-infinite slab. This assumption introduces a systematic geometry…
Self-Verifying Measurement Records: Hash-Linked Evidence Graphs for Hardware Benchmarking
Faruk Alpay, Baris Basaran
Performance numbers reported for hardware are accepted on trust: the reader cannot recompute them, the apparatus is gone, and the silicon itself can be silently wrong, with fleet s…
Residual GPU Cache State on Apple M4 Pro
Faruk Alpay, Baris Basaran
Apple silicon exposes unified CPU-GPU memory, but the cache state left after a completed GPU command is not documented. This paper characterizes that phase boundary on a 14-core Ap…
Naturalness Predicts but Does Not Cause Transferability in Image Encodings of Real-World Streams
Faruk Alpay, Baris Basaran
A common practice converts a one-dimensional signal into an image so that a vision backbone pretrained on natural photographs can be reused for recognition, yet the encoded image i…
Exact Local Annotations for Regular Languages
Faruk Alpay, Baris Basaran
A regular language is recognized by a finite monoid, but a locally checkable explanation of that recognition can have a nontrivial update geometry. We study exact bounded-arity ann…
