Access Controlled Temporal Networks
Proceedings of the 9th International Conference on Agents and Artificial Intelligence, 2017 We define Access-Controlled Temporal Networks (ACTNs) as an extension of Conditional Simple Temporal Networks with Uncertainty (CSTNUs). CSTNUs are able to handle features such as contingent durations and conditional constraints, and have thus been used to model the temporal constraints of workflows underlying business processes.

A Network Access Control Framework for 6LoWPAN Networks [PDF]
Sensors, 2013 Low power over wireless personal area networks (LoWPAN), in particular wireless sensor networks, represent an emerging technology with high potential to be employed in critical situations like security surveillance, battlefields, smart-grids, and in e-health applications. The support of security services in LoWPAN is considered a challenge.

One-Dimensional MUSIC-Type Algorithm for Spherical Microphone Arrays
IEEE Access, 2020 Spherical microphone arrays have been widely used in direction-of-arrival (DOA) estimation in recent years. The conventional multiple signal classification method formulated in spherical harmonic domain (SHMUSIC) is computationally expensive ...

Fusing Depth and Silhouette for Scanning Transparent Object with RGB-D Sensor
International Journal of Optics, 2017 3D reconstruction based on structured light or laser scan has been widely used in industrial measurement, robot navigation, and virtual reality. However, most modern range sensors fail to scan transparent objects and some other special materials, of ...

A Deep Learning Method for DOA Estimation with Covariance Matrices in Reverberant Environments
Applied Sciences, 2022 Acoustic source localization in the spherical harmonic domain with reverberation has hitherto not been extensively investigated. Moreover, deep learning frameworks have been utilized to estimate the direction-of-arrival (DOA) with spherical microphone ...
