...attracted the interest of mathematicians through centuries. For an overview and a historical bibliography, see [3] and [4]. One such problem is the crossed ladders problem (CLP), which can be formulated as follows: Two ladders of length a and b lean against two vertical walls. The ladders cross each other at...

...build on previous results and knowledge to show how both aggregated data and data on single ship behavior can identify key characteristics for ship traffic of different categories. In particular, we use kernel density estimation methods to find relations between ship speed and ice concentration data. Further...

...offshore and onshore power grids”), whose objective is to establish the knowledge basis and methodologies necessary for developing a socio-economically profitable and robust coupled offshore and onshore grid. This includes modelling a future power system with significant presence of both DC and AC grids...

...proximity to the dock and relatively small size. Maritime target tracking has typically employed land masking to filter out land and the dock. However, imprecise land masking makes it difficult to track close-to-dock objects. Our approach uses Light Detection And Ranging (LiDAR) data and maps the docking...

Status on commercial autonomous ships in Norway and Europe, and research activities at SINTEF Ocean. ...

...through pyrolysis and gasification, its compression and its use in gas turbines. Syngas compression can be performed during or after thermal treatment processes. Important points are discussed related to syngas ignition, syngas explosion limit at high temperatures and high pressures and syngas combustion...

...biochar shows versatile physicochemical properties and, can have a wide applicability in diverse fields. Comprehensive studies have been made to characterize biochar produced from various biomass materials, using different production technologies and under different process conditions. However, research...

...stability of energy systems when the share of renewable energy forms (wind and solar) is increasing. Liquid air energy storage (LAES) is a promising technology for storing electricity with certain advantages, such as high energy density and being geographically unconstrained. However, one drawback of a standalone...

The amount of wind power and other timevariable non-dispatchable renewable energy sources (RES) is rapidly increasing in the world. A few power systems are already facing very high penetrations from variable renewables which can surpass the systems' consumption during no-load periods, requiring the energy...

NOWITECH WP5 regarding analysis of access technology and logistic support. The report gives a short overview of the main aspects analysed in the research. In detail, it will present the models developed and applied for evaluation of access technology and logistics support. The results of the research cover...
