2. 1. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

   Author : Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

   Abstract : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). READ MORE

4. 2. Energy efficiency improvements in logistics as a means to environmental sustainability: The case of capacity utilisation in road freight transportation

   Author : Jessica Wehner; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Capacity utilisation; household logistics capability; system levels; distribution structure; logistics system; energy efficiency; last-mile fulfilment; overcapacity; system boundaries; road freight transportation;

   Abstract : The energy consumption in logistics, and especially in road freight transportation, is steadily increasing and with that the greenhouse gas emissions which have a negative impact on the environment. In order to improve environmental sustainability of logistics, a change in the actors’ behaviour and policies is needed since the development of technology alone is not sufficient. READ MORE

5. 3. The Global Fashion System : On its social-ecological intertwinedness

   Author : Celinda Palm; Sarah E. Cornell; Tiina Häyhä; Fredrik Moberg; Kate Fletcher; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainability; Fashion; Social-ecological system; Transdisciplinarity; Critical realism; Positionality; Hållbarhet; Mode; Social-ekologiska system; Tvärvetenskap; Kritisk realism; Positionalitet; vetenskap om hållbar utveckling; Sustainability Science;

   Abstract : The fashion industry contributes to shaping the state of the planet: impacts of production and consumption of textile fast-fashion are rising, and the growing number of sustainability-oriented actions have not slowed current trends. The industry’s (un)sustainability is mainly researched within two epistemic communities: fashion studies concerned with social sustainability, and circular economy focused on material biophysical and technological aspects of material cycles along the value chain.

6. 4. The role of fault management in the embedded system design

   Author : Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Management; Resilient system; Recovery methodology.; Computer Science; datavetenskap;

   Abstract : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.

7. 5. Distributed System Simulation Methods : For Model-Based Product Development

   Author : Robert Braun; Petter Krus; Nigel Johnston; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. READ MORE
