3D Indoor Environment Abstraction for Crowd Simulations in Complex Buildings

Buildings, 2021
This paper presents an approach for the automatic abstraction of built environments needed for pedestrian dynamics from any building configuration. The approach assesses the usability of navigation mesh to perform realistically pedestrian simulation ...

A Tactile Compass for Eyes-Free Pedestrian Navigation [PDF]

, 2011
This paper reports from the first systematic investigation on how to guide people to a destination using the haptic feedback of a mobile phone and its experimental evaluation. The aim was to find a navigation aid that works hands-free, reduces the users' distraction, and can be realised with widely available handheld devices.

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Spatial Characteristics of Walking Areas for Pedestrian Navigation [PDF]

2009 Third International Conference on Multimedia and Ubiquitous Engineering, 2009
We consider how to handle open walking areas in pedestrian navigation applications. Walking areas are a key type of feature which is a major difference between networks of pedestrian navigation and that of road vehicle navigation. Up to recently, little work has been carried out on these features though they are important to route planning algorithm ...

Proactive And Smooth Maneuvering For Navigation Around Pedestrians

2022 International Conference on Robotics and Automation (ICRA), 2022
Navigation in close proximity with pedestrians is a challenge on the way to fully automated vehicles. Pedestrianfriendly navigation requires an understanding of pedestrian reaction and intention. Merely safety based reactive systems can lead to sub-optimal navigation solutions resulting in the freezing of the vehicle in many scenarios.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,
