1. 6. Spatial analysis and modeling of urban transportation networks

   Författare :Jingyi Lin; Yifang Ban; Sten Henning Hansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex networks; transportation systems; network growth; Evolving networks; centrality; urban systems; topology; space syntax; spatial networks; distance effects; gravity laws; planarity; street network patterns; US airline system; China’s aviation system; network efficiency; cellular structure; hierarchy; network representations; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. LÄS MER

3. 7. Network-Based Monitoring of Quality of Experience

   Författare :Junaid Junaid; Markus Fiedler; Patrik Arlos; Astrid Undheim; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality of Experience; Network Performance; Network measurements;

   Sammanfattning : The recent years have observed a tremendous shift from the technology-centric assessment to the user-centric assessment of network services. Consequently, measurement and modelling of Quality of Experience (QoE) attracted many contributions from researchers and practitioners. Generally, QoE is assessed via active and passive measurements.

4. 8. Convolutional Network Representation for Visual Recognition

   Författare :Ali Sharif Razavian; Atsuto Maki; Stefan Carlsson; Josephine Sullivan; Josef Sivic; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convolutional Network; Visual Recognition; Transfer Learning; Computer Science; Datalogi;

   Sammanfattning : Image representation is a key component in visual recognition systems. In visual recognition problem, the solution or the model should be able to learn and infer the quality of certain visual semantics in the image. LÄS MER

5. 9. Perspectives from a human-centred archaeology : Iron Age people and society on Öland

   Författare :Helene Wilhelmson; begravning och social identitet Gravarkeologiska forskargruppen – Död; []
   Nyckelord :HUMANIORA; HUMANITIES; Osteology; bioarchaeology; Iron Age; Scandinavia; 3D; digital; Image Based Modeling; GIS; isotopes; Oxygen; Strontium; Carbon; Nitrogen; trophic level effect; fractionation; chronology; network; Virtual Taphonomy; human-centred archaeology; mortographies; dietary shift; integration; immigration; diet; migration; violence; burial; Viking Age; Öland; island;

   Sammanfattning : The objective of this study was to develop, test and evaluate a specifically defined interdisciplinary approach—the human-centred approach—as applied to a case study, Iron Age Öland. Four themes were selected to highlight different aspects of particular interest in Öland: taphonomy, diet, migration, and social organization. LÄS MER

7. 10. Key Signal Processing Technologies for High-speed Passive Optical Networks

   Författare :Lei Xue; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural network; passive optical network; optical signal processing; digital signal processing; dispersion supported equalization; Optical access network; semiconductor optical amplifier;

   Sammanfattning : With emerging technologies such as high-definition video, virtual reality, and cloud computing, bandwidth demand in the access networks is ever-increasing. Passive optical network (PON) has become a promising architecture thanks to its low cost and easy management. LÄS MER
