Measurement of point spread function for characterization of coregistration and resolution: Comparison of two commercial hyperspectral cameras
(2018)
For spectral cameras, the spatial resolution and coregistration of bands are important performance characteristics. The paper discusses how these can be quantified in a way that is relevant for the spectroscopic processing ...
Field-Testing of High-Level Decentralized Controllers for a Multi-Function Drone Swarm
(2018)
This paper describes the results of initial field testing of a high-level decentralized controller for a swarm of multi-rotor drones. This controller allows the intuitive implementation of a wide variety of swarm behaviors. ...
A New Distributed Localization Algorithm Using Social Learning Based Particle Swarm Optimization for Internet of Things
(2018)
Emerging applications in the Internet of Things (IoT) will depend on the accurate location of thousands of deployed sensors. However, accurate localization of deployed sensors nodes is a classical optimization problem which ...
Hierarchical path planning for walking (almost) anywhere
(2018)
Computerized path planning, not constrained to transportation networks, may be useful in a range of settings, from search and rescue to archaeology. This paper develops a method for general path planning intended to work ...
Image-aided inertial navigation for an Octocopter
(2018)
A typical unmanned aerial system combines an Inertial Navigation System (INS) and a Global Navigation Satellite System (GNSS) for navigation. When the GNSS signal is unavailable, the INS errors grow over time and eventually ...
From food defence to food supply chain integrity
(2017)
Purpose
Consumer confidence in the European food industry has been shaken by a number of recent scandals due to food fraud and accidental contamination, reminding the authors that deliberate incidents can occur. Food ...
Sonar scattering from the sea bottom near the Norwegian coast
(2017)
High false alarm rates on active sonar systems in shallow waters is a well known problem which may be a limiting factor for the sonar performance. One way to reduce the false alarm rate is through supervised learning and ...
Sparse Phase Estimation and Processing of Independent Coherent Processing Intervals
(2017)
Radars employing electronically steering arrays are capable of instantaneously altering the direction of the beam along with other parameters. This flexibility offers great opportunities to a radar as it may e.g. divide ...
USRP based cognitive radar testbed
(2017)
Cognitive radar is a relatively new field of research and the existence of low cost experimental testbeds is limited. This work will show the development of a low cost experimental testbed for experimental validation of ...
Effects of Cultural Diversity on Trust and its Consequences for Team Processes and Outcomes in Ad Hoc Distributed Teams
(2011)
This quasi-experimental study explores trust as a mediator, explaining how cultural diversity may affect team processes and outcomes in distributed ad hoc teams. Data were collected both through self-report and direct ...
