Automatic Multi-Camera Extrinsic Parameter Calibration Based on Pedestrian Torsors ^†

Sensors, 2019
Extrinsic camera calibration is essential for any computer vision task in a camera network. Typically, researchers place a calibration object in the scene to calibrate all the cameras in a camera network.

The Relationship Between Pedestrian’s Assessment of Street Environments and Physical Conditions [PDF]

, 1987
1.1.1 Any new road, road improvement or traffic management scheme could affect pedestrian journeys in its locality or elsewhere. Some journeys may be affected directly, with severance caused where the new road or road improvement cuts across a ...

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

Advanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

THE INFLUENCE OF SIDE FRICTION ON TRAFFIC ON FATIMA AL-ZAHRA STREET IN KARBALA: CAUSES, RESULTS AND SOLUTIONS

International Journal of Advanced Studies
Side friction is considered one of the main reasons for reducing the efficiency of traffic in urban streets and is caused by a number of factors, such as parking vehicles on the side of the road, pedestrians crossing in places not intended for them ...

A microscopic simulation model for pedestrian-pedestrian and pedestrian-vehicle interactions at crosswalks

PLOS ONE, 2017
This study aims to develop a microscopic pedestrian behavior model considering various interactions on pedestrian dynamics at crosswalks. Particularly, we take into account the evasion behavior with counter-flow pedestrians, the following behavior with leader pedestrians, and the collision avoidance behavior with vehicles.

Start, Stop, Rewind, Repeat—Cyclic Exposure of Adipose Stromal Cells‐derived Cartilage Organoids to Chondrogenic and Proliferative Cues to Achieve Scaled‐up and Customizable Bone Formation by Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of

Designing and Planning of Studies of Driver Behavior at Pedestrian Crossings Using Whole-Vehicle Simulators

Applied Sciences
The paper presents a proposed methodology for designing and planning research on driver behavior at pedestrian crossings using whole-vehicle simulators. It was assumed that dedicated research should be conducted in specific problem contexts. The problems

Filtered local pattern descriptor for face recognition and infrared pedestrian detection

The Journal of Engineering, 2017
In recent decades, the local pattern descriptor has achieved tremendous success in the field of face recognition, pedestrian detection, and image texture analysis. This study presents a generic approach, called the filtered local pattern descriptor (FLPD)

Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.
