A dataset for mechanical mechanisms

Authors: F Ghezelbash, AH Eskandari, AJ Bidhendi

Source: arXiv preprint arXiv:2409.03763

Year: 2024

We present a new dataset of ~9,000 images of mechanical mechanisms (2D and 3D) with text descriptions to aid AI-driven design. We fine-tuned Stable Diffusion and BLIP-2 models using this data, showing promise for generating 3D sketches, but 2D sketches need work. Our dataset, though limited in size, represents a first step towards using AI for mechanism design.

Plant blindness and diversity in AI language models

Authors: A Geitmann, AJ Bidhendi

Source: Trends in Plant Science

Year: 2023

We uncover "plant blindness" in large language models, revealing inconsistencies in their understanding of the plant kingdom. This highlights an urgent need: scientists must actively guide AI training to ensure diverse and accurate representations of the natural world.

3D visualization of microtubules in epidermal pavement cells

Authors: AJ Bidhendi, B Altartouri, A Geitmann

Statistical shape modeling of the human ear canal for designing hearing protection devices and auditory wearables

Authors: F Ghezelbash, K Braun, AJ Bidhendi, J Bouchard-Roy

Source: Canadian Acoustics, 2023, vol. 51, issue 3, pp. 115-116

We've developed a new method for designing better ear devices like headphones and earplugs. By scanning and analyzing ear canals from 86 people, we created a model that captures the diverse shapes and sizes of ears. This model allows us to design devices that fit more comfortably and work more effectively, improving comfort, hearing protection and user experience.

Evaluating mechanical comfort of ear tips: An experimental-computational approach

Authors: AJ Bidhendi, K Braun, J Bouchard-Roy, F Ghezelbash

Source: Canadian Acoustics, 2023, vol. 51, issue 3, p. 114

To improve the comfort of earplugs and earbuds, we developed a system to measure how different designs interact with the ear canal. This involves 3D-printed ear canal models, finite element simulations, and feedback from testing on real users.

Cell shape formation through material heterogeneity in the plant cell wall

Authors: Anja Geitmann, AJ Bidhendi, Bara Altartouri

Source: APS March Meeting Abstracts, N00.260

Year: 2022

Plant cells develop intricate shapes through a fascinating interplay of internal pressure and precisely controlled cell wall properties. Using advanced microscopy and computational modeling, we reveal how pectin and cellulose microfibrils orchestrate this process, even showing how "buckling" can initiate unique forms. This work offers insights into plant development and inspires new bio-inspired materials.

Cytoskeletal regulation of primary plant cell wall assembly

Authors: Y Chebli, AJ Bidhendi, K Kapoor, A Geitmann

Source: Current Biology, 31(10), R681-R695

Year: 2021

This review explores the fascinating interplay between the plant cytoskeleton and cell wall assembly during development. The cytoskeleton orchestrates the delivery of cell wall materials and guides their arrangement to create anisotropic properties crucial for shaping cells. This process is dynamic and responsive to both internal and external cues, highlighting the intricate feedback loops that govern plant growth and morphogenesis.

Modeling the nonlinear elastic behavior of plant epidermis

Authors: AJ Bidhendi, H Li, A Geitmann

Source: Botany, 98(1), 49–64

Year: 2020

We explore the elastic behavior of onion skin under tension, finding it to be surprisingly complex and nonlinear. This challenges the common assumption that plant tissues behave like simple springs. By applying advanced material models, we can accurately capture this nonlinearity, leading to a deeper understanding of plant biomechanics. This knowledge not only helps us understand how plants grow and develop, but also inspires the design of new, bio-inspired materials with unique properties.
