Beyond the Frontier: Predicting Unseen Walls from Occupancy Grids by Learning from Floor Plans
In this paper, we tackle the challenge of predicting the unseen walls of a partially observed environment as a set of 2D line segments, conditioned on occupancy grids integrated along the trajectory of a 360° LIDAR sensor. A dataset of such occupancy grids and their corresponding target wall segments is collected by navigating a virtual robot between a set of randomly sampled waypoints in a collection of office-scale floor plans from a university campus. The line segment prediction task is for…

Modeling fibrous tissue in vascular fluid-structure interaction: a morphology-based pipeline and biomechanical significance
We propose a suite of technologies for analyzing the interaction between anisotropic arterial walls and blood flow for subject-specific geometries. Utilizing an established lumen modeling strategy, we present a comprehensive pipeline for generating the thick-walled artery models. Through a specialized mesh generation procedure, we obtain the meshes for the arterial lumen and wall with mesh continuity across the interface ensured. Exploiting the centerline information, a series of procedures is …

I'm reading The Song of Achilles, which is either a gay romance novel or else a scholarly retelling of The Iliad or both. The prose style is interesting, lyrical and just a bit foreign. It feels like reading translations of Homer only modern and much easier to follow. I'm not normally one for wrought prose but this works to transport me.
Their whispers choked me, turned the food in my mouth to ash. I pushed away my plate and sought out corners and spare halls where I might sit undisturbed, except for the occasional passing servant. My narrow world narrowed further: to the cracks in the floor, the carved whorls in the stone walls. They rasped softly as I traced them with my fingertip.
“I heard you were here.” A clear voice, like ice-melted streams.
My head jerked up. I was in a storeroom, my knees against my chest, wedged between jars of thick-pressed olive oil. I had been dreaming myself a fish, silvered by sun as it leapt from the sea. The waves dissolved, became amphorae and grain sacks again.
