Optimization and stress testing are key aspects of thedesign and verification process for large, high-risksystems. Optimization is about improving the capabilitiesand performance of a system; stress testing is aboutuncovering its weaknesses and faults. Both require aquantitative representation of...
Cross-chain bridges are solutions that enable interoperability between heterogeneous blockchains. In contrast to the underlying blockchains, the bridges often provide inferior security guarantees and have been targets of hacks, causing damage in the range of 1.5 to 2 billion USD in 2022. The current...
This paper provides a Panarctic review of the regulations, loads, and treatment of wastewater (WW) discharged in the Arctic region. WW regulation principles and practices vary across the Arctic nations, being based either on effluent quality criteria (Canada, Sweden and Cruise ships), recipient...
The oxidative degradation of technically relevant types of Kraft lignin is efficiently accomplished by a significantly improved two‐step protocol. The key is the use of highly concentrated peroxodicarbonate solution which selectively oxidizes the lignin particles at moderate temperature which are...
Human activity recognition (HAR) involves using sensors to collect human data, which is then analyzed to identify their activities. HAR has numerous applications across various fields. One significant area is human-robot interaction (HRI). Recognizing user activities provides robots with valuable...
Carbon capture from hard-to-abate industries is essential. This study investigates the effect of stripper pressure on the performance of amine-based CO capture from cement flue gas, using the CESAR1 solvent. Through a rigorous data filtering and binning methodology, experimental results were...
This study comprehensively examines the effect of casting route—sand versus permanent mold—on the microstructural evolution and mechanical performance of A360 aluminum alloy produced under identical alloy composition. The objective was to elucidate how differences in cooling rate and solidification...
The landscape of cooker hood trends is evolving in Europe. There is a notable shift towards interest in recirculating and downdraft solutions as alternatives to traditional extracting cooker hoods. However, there is a lack of comprehensive documentation regarding their capture efficiency and...
The rise in photovoltaic (PV) waste across all stages of the PV value chain has created a need for efficient recycling solutions to reintroduce these materials into use. In response, the EU project (ICARUS) is exploring several recycling routes for key waste streams, including silicon kerf, quartz...
A defect engineering strategy is employed to produce defective calcium‐doped TiO 2 nanomaterials (Ca:TiO 2 ), which are subsequently incorporated into cellulose‐based membranes. Structural defects, including vacancies, stacking faults, grain boundaries and voids emerged from the interplay between...
Liquefaction of natural gas requires energy intensive refrigeration. A fair comparison of different process concepts and energy efficient designs requires some use of optimization. In near optimal designs, the driving forces in heat transfer are small. Thus, rigorous thermodynamics providing...
Integrating Artificial Intelligence (AI) with the Industrial Internet of Things (IIoT) has transformed industrial processes, enhancing productivity, quality control, and operational efficiency. However, ensuring the precision and reliability of sensor-generated data remains a critical challenge due...
As regulation of ship emission established, using liquefied natural gas (LNG) as ship fuel is one of the method to reduce ship emission. For LNG carrier, boil-off gas (BOG) generated from the storage tank can be used as fuel and it is economical to adopt BOG re-liquefaction system on the vessel. In...
Solubility of ethane and propane in aqueous solutions of N-methyldiethanolamine (MDEA, 25 and 50 wt %), 2-(2-aminoetoxy)ethanol or diglycolamine (DGA, 35 and 52.5 wt %), diethanolamine (DEA, 35 wt %), ethanolamine (MEA, 14.6 wt %), and a mixture of MDEA and piperazine (42.1 wt % MDEA +8 wt % Pz) was...
... Process synthesis methods have only recently been applied for the design of CO2 capture systems. At the crux of the CO2 capture process is a separation technology (sorbent, membrane or phase separation) applied to CO2/N2, CO2/H2 or O2/N2 systems. Development of novel sorbents and membranes have...
The GW approximation represents the state-of-the-art ab-initio method for computing excited-state properties. Its execution requires control over a larger number of parameters, and therefore, its application in high-throughput studies is hindered by the complex and time-consuming convergence process...
Direct air capture (DAC) is a pivotal technology for achieving net-zero emissions, yet its scalability is constrained by energy intensity and material limitations. This work critically examines the current landscape of solid sorbents for DAC, focusing on their performance, durability, and...
Distributed Acoustic Sensing (DAS) is revolutionizing passive acoustic monitoring, offering the potential to create vast arrays of uniformly spaced virtual hydrophones every few meters. Applications are expanding rapidly and now include marine mammal monitoring, which often requires higher (>...
