Membrane technology for CO₂/H₂ separation, especially when using CO₂-selective membranes to keep H₂ on the high-pressure retentate side, has been considered promising and energy-efficient for further H₂ transport and utilization. This work prepared and optimized a CO₂-selective membrane based on...

Purpose: The purpose of this paper is to share the experience of implementing Toyota Kata for an ETO manufacturer in the Norwegian construction industry. The authors present observations and experiences from the application of Toyota Kata, with the aim of bringing out critical success factors and a...

The use of food grade wild-captured species as bait for other fisheries questions the sustainability of food production. In pot fisheries, bait is an important factor determining the effectiveness of the gear. In snow crab (Chionoecetes opilio) fishery, the pots are normally baited with squid (Illex...

Calanus finmarchicus is a keystone zooplankton species that is commercially harvested and is critical in sustaining many important fisheries in the North Atlantic. However, due to their patchy population distributions, they are notoriously difficult to map using traditional ship-based techniques...

Pots are widely used fishing gear type for targeting different crustacean and fish species. Pot entrance size and design are among the most important technical parameters that influence the catch efficiency of certain species. An optimal pot entrance design should allow an efficient entry for the...

The Internet of Things (IoT) and Cyber-Physical Systems (CPS) are the backbones of Industry 4.0, where data quality is crucial for decision support. Data quality in these systems can deteriorate due to sensor failures or uncertain operating environments. Our objective is to summarize and assess the...

To be competitive in dynamic and global markets, manufacturing companies are continuously seeking to apply innovative production strategies and methods combined with advanced digital technologies to improve their flexibility, productivity, quality, environmental impact, and cost performance. Zero...

This paper presents a method to automatically generate robot welding programs from CAD to address the ever-constant demand for product customisation. Furthermore, to ensure that proper welding operations and structural integrity are met, the generated programs also consider the welding conditions...

Lean manufacturing has experienced massive changes under the influence of Industry 4.0 as the automation of lean practices has become common among manufacturing companies in many countries and across different industries. Automating lean practices promises several opportunities for growth and...

This article proposes the use of Geometric Dimensioning and Tolerancing (GD &T) information from STEP AP242 for robotic manufacturing applications. This information can be directly added to the relevant features of the 3D model as per Model Based Definition methodology during the design phase of the...

The gillnet fishery targeting Asian paddle crab (Charybdis japonica) is an important commercial fishery in the Yellow Sea of China. However, low catch rates represent a challenge, and solutions for improving the catch efficiency are crucial for economical sustainability in this fishery. Therefore...

Testing av alle ZEN nøkkelindikatorer på Ydalir. Denne rapporten tester ut alle ZEN nøkkelindikatorene i ZEN-pilotområdet Ydalir. Resultatene skal brukes i videreutvikling og verifisering av ZEN-definisjonen og vil gi nyttige innspill til utforming av en ZEN prosessveileder. Resultatene gir forslag...

In order to optimize the size selectivity of demersal trawl targeting Banded Scad, Alepes djedaba, in the South China Sea (SCS), we tested and compared the selective properties of four experimental codends. These codends included two diamond-mesh codends (T0 codends) with different mesh openings...

In Pacific halibut (Hippoglossus stenolepis) longline fisheries in the eastern North Pacific Ocean bycatch of yelloweye rockfish (Sebastes ruberrimus) is a concern as their stock status along the U.S. West Coast is “rebuilding” from being “overfished”, the southeast Alaska stock has shown a...
