2. 1. Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene : Insights from biomarkers and climate model simulations

   Author : Lars Petter Hällberg; Malin Kylander; Frederik Schenk; Rienk Smittenberg; David Naafs; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Holocene; Late Glacial; biomarkers; organic geochemistry; climate model; hydrogen isotopes; stable isotopes; paleoclimate; alkanes; GDGT; brGDGT; H-GDGT; bacterial community shifts; paleothermometry; precipitation reconstruction; peat; geokemi; Geochemistry;

   Abstract : Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e. READ MORE

4. 2. Seaward Landward : Investigations on the archaeological source value of the landing site category in the Baltic Sea region

   Author : Kristin Ilves; Frands Herschend; Ingmar Jansson; Antony Firth; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Archaeology; Coastal archaeology; Maritime archaeology; Maritime cultural landscape; Landing sites; Harbours; Critical historiography; Sociology of landing sites; Model of interaction; Methodology; Shore displacement; Phosphate analysis; Baltic Sea region; Archaeology; Arkeologi;

   Abstract : There is a tendency in archaeology dealing with watercraft landing sites in a wider context to assume a direct relationship between sites in coastal and shore-bound areas and the practise of landing, without any deeper practical or theoretical exploration of the reality of any such relationship. This problem has its origins in the poor archaeological and conceptual definitions of watercraft landing sites obstructing any real understanding of the role of these sites in the maritime cultural landscape.

5. 3. Model Fidelity in Mission Scenario Simulations for Systems of Systems : A Case Study of Maritime Search and Rescue

   Author : Sofia Schön; Petter Krus; Christopher Jouannet; Carina Marcus; Kristian Amadori; Alessandro Bertoni; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Systems of Systems (SoS) represent a view where individual, independent systems named Constituent System (CS) collaborate to achieve overarching capabilities not attainable by a single CS alone. In cyberphysical systems, CS can be engineered entities like boats or aircraft, when they collaborate in an environment it can be viewed as an SoS. READ MORE

6. 4. Circular Business Models that Extend Product Value : Going Beyond Recycling to Create New Circular Business Opportunities

   Author : Katherine Whalen; Internationella miljöinstitutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular business model; product life extension; obsolescence; circular economy; business model; reuse; repair; refurbishment; sustainability strategies; sustainability education;

   Abstract : Over the past ten years, significant industry, policy, and scientific attention has been given to the ‘circular economy’, which aims to create a more sustainable society by decoupling economic growth from resource consumption. Firms are expected to play a significant role in the shift to a circular economy model by implementing circular business models that encourage prolonged use of products, components, and materials.

7. 5. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

   Author : Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. READ MORE
