A 3D reactive collision avoidance algorithm for underactuated underwater vehicles
(2020-02-28)
Avoiding collisions is an essential goal of the control system of autonomous vehicles. This paper presents a reactive algorithm for avoiding obstacles in a three‐dimensional space, and shows how the algorithm can be applied ...
Leakage rate of the nerve agent tabun from sea-dumped munition
(2020-10)
The leakage rate of nerve agents from corroded munition on the sea floor has been estimated by using table sugar as
a simulant for the nerve agent tabun. Laboratory experiments were conducted with a full-size model of a ...
Studying the effect of source proximity in sperm whales and continous sonar in pilot whales using operational sonars - the 3S-2019-OPS cruise report
(2020-07)
The 3S project is an international collaborative effort with the aim to investigate behavioral
reactions of cetaceans to naval sonar signals. The objectives of the third phase of the project
are to investigate if exposure ...
Påvirkningsoperasjoner i sosiale medier - oversikt og utfordringer
(2020-06-17)
Formålet med denne rapporten er todelt: å gi en omfattende oversikt over hvordan stater bruker
sosiale medier for å prøve å påvirke befolkningen i andre land, og å undersøke hvordan slike
operasjoner har blitt håndtert. ...
Utilizing Zirconium MOF-functionalized fiber substrates prepared by molecular layer deposition (MLD) for toxic gas capture and chemical warfare agent degradation
(2021-09-12)
Metal–organic frameworks (MOFs) are a class of porous organic-inorganic
solids extensively explored for numerous applications owing to their catalytic activity and high surface area. In this work MOF thin films deposited
in ...
Systemic approaches for emission reduction in industrial plants based on physical accounting: example for an aluminium smelter
(2022-01-22)
Greenhouse gas (GHG) accounting in industrial plants usually has multiple purposes, including mandatory reporting, shareholder and stakeholder communication, developing key performance indicators (KPIs), or informing ...
A neural network framework for binary classification of radar detections.
(2021-09-17)
A desired objective in radar target detection is to satisfy two very contradictory requirements: offer a high probability of detection with a low false alarm rate. In this paper, we propose the utilization of artificial ...
Reactive Collision Avoidance for Underactuated Surface Vehicles using the Collision Cone Concept
(2021-08)
Avoiding collisions is a crucial task for autonomous systems. Many strategies for avoiding obstacles have been proposed, yet the problem of having underactuated dynamics is rarely addressed in previous studies of collision ...
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(2021-11-01)
Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ...
