2. 16. A System-of-Systems Approach for Enhancing Asset Management of Railway System

   Author : Jaya Kumari; Ramin Karim; Adithya Thaduri; Pierre Dersin; Miguel Castaño Arranz; Mirka Kans; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railways rolling stock; system-of-systems; asset management; maintenance; fleet management; industrial AI; digitalisation; Operation and Maintenance Engineering; Drift och underhållsteknik;

   Abstract : In Sweden, railway transport of freight and passengers is a significant portion of the total transport system. The demand for railway transport is forecasted to increase in the coming decades. One of the main reasons for this ever-increasing demand is the requirement for sustainable transport, nationally and globally. READ MORE

4. 17. Ecosystems in the Anthropocene: the role of cropland management for carbon and nitrogen cycle processes

   Author : Stefan Olin; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon; Nitrogen; DVM; Ecosystem modelling; Cropland; Management; Yields;

   Abstract : Through deforestation and conversion of natural ecosystems to croplands and pastures, have humans released vast amounts of carbon (C) dioxide (CO2) into the atmosphere. Roughly one third of the cumulative anthropogenic emissions until today stem from these practices, the remainder being mostly due to fossil fuel combustion. READ MORE

5. 18. Privatisation of the IT Sector in Sweden

   Author : Kent Springdal; Företagsekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomiska system; ekonomisk teori; ekonometri; organisational change; Privatisation; property rights; transformation; Economics; public choice; econometrics; economic theory; economic systems; Nationalekonomi; economic policy; management; Företagsledning; Management of enterprises; ekonomisk politik;

   Abstract : The majority of research on privatisation has been driven by, inter alia, economics. Some economists have argued that private ownership introduces capital market pressures into inefficient state bureaucracies. Private property rights are expected to maximise the incentives for management to achieve a high level of production efficiency. READ MORE

6. 19. Integrated design and construction for bridges: key aspects and benefits

   Author : Daniel P T Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrialized construction; ICT; concurrent engineering; BIM; integrated design; Lean Construction; Integration in construction;

   Abstract : The rate of productivity and innovation capacity within the Swedish construction industry of today is perceived to lead to a poor return of investment within infrastructures. Bridges, are commonly designed for a long service-life, and all stages after realization is greatly dependent on and constrained by decisions made during design and construction of the structure.

7. 20. Fatigue evaluation of welded details – using the finite element method

   Author : Mustafa Aygül; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the finite element method; welded details; effective notch stress method; Hot-spot stress method; fracture mechanics;

   Abstract : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.
