1. 36. Framework for cost and weight efficient conceptual design of automotive composite body structures

   Författare :Per Mårtensson; Dan Zenkert; Kevin Potter; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composites automotive cost weight body structure; Flyg- och rymdteknik; Aerospace Engineering; Fiber- och polymervetenskap; Fibre and Polymer Science; Transportvetenskap; Transport Science;

   Sammanfattning : The automotive industry is facing a great challenge - reducing the weight of their vehicles. Carbon fibre composites are regarded by many as the only real option as traditional engineering materials are now running out of potential for further weight reduction. LÄS MER

3. 37. Intermodal container transport logistics to andfrom Malaysian ports : Evaluation of Customer requirements and environmental eff‡ects

   Författare :Sharin Nasir; Bo-Lennart Nelldal; Kenth Lumsden; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

   Sammanfattning : Malaysian ports’ container volumes are expected to increase to 36.6 million TEUs in 2020 compare to 12 million TEUs in 2005. Almost 45% of the container volumes are local containers entering the Malaysian hinterland. LÄS MER

4. 38. Collaborative Measures : Challenges in Airport Operations

   Författare :Simon Okwir; Jannis Angelis; Pernilla Ulfvengren; Felipe Ruiz; Mats Winroth; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Performance Measurement; Airport Operations; Collaboration Decision Making; Industriell ekonomi och organisation; Industrial Economics and Management; Planering och beslutsanalys; Planning and Decision Analysis; Transportvetenskap; Transport Science; Industrial Information and Control Systems; Industriella informations- och styrsystem;

   Sammanfattning : Over the last 20 years, internal use of Performance Management(PM) within organizations has become much more complex in terms measurement techniques and approaches as well as their deployment within different organizational structures. In contrast to the traditional use of PM as an intra-organizational system, the emergence of networked operations, has extended organizational boundaries of Performance Management System (PMS) to new operational settings where actors often deal with a challenge of Collaborative Measures.

5. 39. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures

   Författare :Ibrahim Onifade; Björn Birgisson; Linbing Wang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-based models; damage; X-ray computed tomography; continuum plasticity mechanics CPM; effective micro-crack stress; Transportvetenskap; Transport Science;

   Sammanfattning : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this  is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.

7. 40. MEILI : Multiple Day Travel Behaviour Data Collection, Automation and Analysis

   Författare :Adrian Corneliu Prelipcean; Yusak Octavius Susilo; Gyözö Gidofalvi; Zachary Pattersson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multiple day travel diary collection; trajectory segmentation; travel mode destination and purpose inference; travel diary collection system comparison; travel pattern stability and variability over time; Transportvetenskap; Transport Science; Computer Science; Datalogi; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Researchers' pursuit for the better understanding of the dynamics of travel and travel behaviour led to a constant advance in data collection methods. One such data collection method, the travel diary, is a common proxy for travel behaviour and its use has a long history in the transportation research community. LÄS MER
