Visual Terrain Relative Navigation: Pose Estimation, Neural Fields, and Verification
… whether newly emerging Neural Radiance Fields (NeRF) can be efficiently leveraged as a map for visual localization. We propose a NeRF-based localization pipeline coined Loc-NeRF which uses a particle filter backbone to perform monocular camera pose estimation utilizing NeRF. Thirdly, since TRN …

LARGE-SCALE NEURAL 3D SCENE RECONSTRUCTION, RENDERING, AND BEYOND
… real-world applications. While techniques like NeRF and 3D Gaussian Splatting (3DGS) show promise, they face challenges in scalability, robustness to imperfect camera poses, and consistency across distributed captures. To address these, we introduce a series of innovations. For scalability, …

Recovery of Herschel-Bulkley Fluid Parameters from Video via Differentiable Simulations
… method that combines neural radiance fields (NeRF), which map 3D scene coordinates to color and density using deep neural networks, with the material point method (MPM), a simulation technique that represents materials as moving points capable of large deformation. Our approach aims to …

Editing Conditional Radiance Fields
A neural radiance field (NeRF) is a scene model supporting high-quality view synthesis, optimized per scene. In this thesis, we explore enabling user editing of a category-level NeRF – also known as a conditional radiance field – trained on a shape category. Specifically, we introduce a method for …

The exploration of concepts for projectile toys
… similar to those used in the current line of Nerf® products. The eDarts created a tracer shot or laser bullet" effect when used in low light conditions. Safety, projectile mass, and axially symmetric loading were the greatest issues of concern. The final suggested eDart incorporated a standard …

Modulation des réflexes intra et inter-membres en fonction de la vitesse et de la coordination gauche-droite chez le chat intact et spinal
Les nerfs péronier superficiel (PS) et radial superficiel (RS) détectent respectivement le contact d’un objet avec la zone dorsale des pattes postérieures et antérieures, et induisent une réponse généralisée à l’ensemble du corps afin de traverser l’obstacle. Lors de la marche, ces réponses sont …

Design of repeating projectile toy based on bistable spring propulsion
… method for the standard 1.75" foam balls used in Nerf® projectile toys. This technology was developed at M.I.T. by William Fienup and Barry Kudrowitz, who designed a single-shot hand-popper that utilized a large bistable spring. The goal of this research was to design and develop a projectile toy …

Lifting 2D Vision Models into Structured Scene Representations
… Learned scene representations such as NeRF and Gaussian Splatting do not support additional functionality besides novel view rendering. The world is compositional: a scene can be described in terms of objects. Correspondingly, we present a lifting solution for efficient open-set 3D …

Image-based 3D Reconstructions via Differentiable Rendering of Neural Implicit Representations
… received great attention, Neural Radiance Field (NeRF) achieves clean and straightforward reconstruction of volumetric geometry and non-Lambertian appearance together from a dense set of RGB images. Various other forms of representations or modifications have also been proposed to handle specific …

The effect of corporate bonds spread variability on non-financial firms’ financing structure: further evidence from emerging markets
… non-financial firms since these are the central nerf of every market. Based on the above, we suggest investigating the role of financial and economic development on financing decisions for non-financial firms in emerging economies in the context of market and bank-based financial models.
