Gauge Fields and M-Fivebrane Dynamics [PDF]

, 1997
In this paper we obtain both the vector and scalar equations of motion of an M-fivebrane in the presence of threebrane solitons. The resulting equations of motion are precisely those obtained from the Seiberg-Witten low energy effective action for N=2 ...

Mapless Online Detection of Dynamic Objects in 3D Lidar

, 2018
This paper presents a model-free, setting-independent method for online detection of dynamic objects in 3D lidar data. We explicitly compensate for the moving-while-scanning operation (motion distortion) of present-day 3D spinning lidar sensors.

Aggregation Periods Influence Step Count Error in Low-Power Wearables

Sensors
Wearable sensors are increasingly used to monitor physical activity, yet low-power devices often rely on data aggregation to conserve battery life, potentially impacting measurement accuracy.

The morphing of fluid queues into Markov-modulated Brownian motion [PDF]

, 2014
Ramaswami showed recently that standard Brownian motion arises as the limit of a family of Markov-modulated linear fluid processes. We pursue this analysis with a fluid approximation for Markov-modulated Brownian motion.

Stability Control of a Biped Robot on a Dynamic Platform Based on Hybrid Reinforcement Learning

Sensors, 2020
In this work, we introduced a novel hybrid reinforcement learning scheme to balance a biped robot (NAO) on an oscillating platform, where the rotation of the platform is considered as the external disturbance to the robot. The platform had two degrees of

Tippe Top Equations and Equations for the Related Mechanical Systems [PDF]

, 2012
The equations of motion for the rolling and gliding Tippe Top (TT) are nonintegrable and difficult to analyze. The only existing arguments about TT inversion are based on analysis of stability of asymptotic solutions and the LaSalle type theorem. They do
