Object detection in maritime environments is a challenging problem because of the continuously changing background and moving objects resulting in shearing, occlusion, noise, etc. Unluckily, this problem is of critical importance since such failure may result in significant loss of human lives and economic loss. The available object detection methods rely on radar and sonar sensors. Even with the ...

In recent years, the concept of Maritime Autonomous Surface Ships (MASSs) has gotten attention both from the research community and shipping industry. The recent development in advanced sensing, communication, and control technologies makes it possible to operate such vessels remotely through Onshore Operation Centers (OOCs). However, there are still several challenges that need to be addressed ...

Autonomous shipping has received extensive attention from the maritime industry as well as the respective research, academic and training institutes, owing to its major benefits related to cost and safety over traditional shipping in many situations. In reality, the implementation of autonomous technology in shipping can face numerous challenges from the technology and regulatory perspectives. ...

I forbindelse med etableringen av Universitetet i Tromsø ble det undersøkt om det var gode nok forhold for infrarøde astrofysiske observasjoner i lange, kalde vinternetter i Indre Troms. Mest klarvær om vinteren fant vi i ytre del av Skibotndalen. Fjellet Addjet (1405 m.o.h) ble i 1974 foreslått som sted for observatorium. Dette ble imidlertid vurdert for krevende og kostbart. Det ble i stedet vedtatt ...

The Last Interglacial period (LIG) was characterized by a long-term Arctic atmospheric warming above the preindustrial level. The LIG thus provides a case study of Arctic feedback mechanisms of the cryosphere-ocean circulation-climate system under warm climatic conditions. Previous studies suggested a delay in the LIG peak warming in the North Atlantic compared to the Southern Ocean and evoked the ...

Troms Kraft have identified a location in Kvænangen, Norway, for a new wind power plant with promising wind resources. However, the site is in an arctic climate with mountainous terrain exposed to severe icing conditions. Assessments of icing conditions at proposed locations for new wind power plants in areas exposed to icing is crucial to identifying icing related challenges. This paper investigates ...

The optimized network architectures and interconnect technologies employed in high-performance cloud computing environments introduce challenges when it comes to developing monitoring solutions that effectively capture relevant network metrics. Moreover, network monitoring often involves capturing and analyzing a large volume of network traffic data. This process can introduce additional overhead ...

The overlying snow cover on sea ice has a profound influence on what lies below. Being both highly optically reflective and thermally insulating, the snow influences the rate and timing with which the sea ice grows and melts seasonally. The shade introduced by the snow radically reduces the light intensity in and under the ice, affecting which organisms can survive there and how active they can be. ...

Here we present an effective nickel-catalyzed carbonylative cross-coupling for direct access to alkyl aryl ketones from readily accessible redox-activated tetrachlorophthalimide esters and aryl boronic acids. The methodology, which is run employing only 2.5 equivalents of CO and simple Ni(II) salts as the metal source, exhibits a broad substrate scope under mild conditions. Furthermore, this ...
