Imitation dynamics in a game of traffic [PDF]

open access: yes, 2013
We study a model of traffic where drivers adopt different behavioral strategies. These can be cooperative or defective according to a driver abiding or not by a traffic rule.

Cognitive Anti-Deception-Jamming for Airborne Array Radar via Phase-Only Pattern Notching With Nested ADMM

open access: yesIEEE Access, 2019
Deceptive jamming may not only induce a large amount of false alarms and deteriorate the target detection performance, but also lead to degraded space-time adaptive processing (STAP) performance in an airborne radar.

A bistable soft gripper with mechanically embedded sensing and actuation for fast closed-loop grasping [PDF]

open access: yes, 2019
Soft robotic grippers are shown to be high effective for grasping unstructured objects with simple sensing and control strategies. However, they are still limited by their speed, sensing capabilities and actuation mechanism.

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

A column of grains in the jamming limit: glassy dynamics in the compaction process [PDF]

open access: yes, 2003
We investigate a stochastic model describing a column of grains in the jamming limit, in the presence of a low vibrational intensity. The key control parameter of the model, $\epsilon$, is a representation of granular shape, related to the reduced void ...

Beyond traffic jams: public perceptions of Jabodetabek Commuter Line (KRL) System for sustainable urban development

open access: yesIOP Conference Series: Earth and Environmental Science, 2023
Abstract Jabodetabek Commuter Line (KRL) is an essential transportation infrastructure that connects the city’s suburbs with the central business district. Despite the system’s expansion in recent years, there needs to be more research on how the public perceives the KRL system as a sustainable transportation option and how these ...

Addressing GNSS Vulnerabilities in AAM: A Multi-Modal UAV Testbed for Redundant and Reliable Navigation [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Advanced Air Mobility (AAM) aims to revolutionize transportation by enabling on-demand, low-altitude movement of people and goods using Vertical Take-Off and Landing (VTOL)-capable vehicles (VCAs), but achieving precise and reliable navigation remains a ...
