2. 1. Investigation of vanadium-containing oxide systems : CALPHAD and experiments

   Author : Yang Yang; Malin Selleby; Caisa Samuelsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calphad; thermodynamic modelling; compound energy formalism; evaporation kinetics; activation energy; TGA; activity;

   Abstract : Fundamental studies on thermodynamic properties of vanadium-containing oxides systems are essential to understand practical vanadium metallurgical process. The CALPHAD technique is here applied to the thermodynamic modelling of the V-O, Ca-V-O and Ti-V-O systems. The compound energy formalism is used for all the solution phases. READ MORE

4. 2. Time-lapse Analysis of Borehole and Surface Seismic Data, and Reservoir Characterization of the Ketzin CO2 Storage Site, Germany

   Author : Can Yang; Christopher Juhlin; Rob Arts; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amplitude anomaly; AVO analysis; Carbon dioxide storage; Moving source profile survey; Reflection coefficient; Reservoir characterization; Static correction; Time-lapse analysis; Geophysics with specialization in Seismology; Geofysik med inriktning mot seismologi;

   Abstract : The CO2SINK (and CO2MAN) project is the first onshore CO2 storage project in Europe. The research site is located near the town of Ketzin, close to Potsdam in Germany. Injection started in June 2008, with a planned injection target of 100,000 tonnes of CO2. READ MORE

5. 3. Efficient Map Matching and Discovery of Frequent and Dominant Movement Patterns in GPS Trajectory Data

   Author : Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; map matching; contiguous sequential pattern mining; contiguous sequential pattern comparison; movement pattern detection; Kartmatchning; sammanhängande sekventiellt mönster utvinning; sammanhängande sekventiellt mönster jämförelse; rörelsemönster detektering; Geoinformatics; Geoinformatik;

   Abstract : The wide deployment of Global Positioning System (GPS) sensors for movement data collection has enabled a wide range of applications in transportation and urban planning. Frequent and dominant movement patterns embedded in GPS trajectory data provide valuable knowledge including the spatial and temporal distribution of frequent routes selected by the tracked objects and the regular movement behavior in certain regions.

6. 4. Discovering Contiguous Sequential Patterns in Network-Constrained Movement

   Author : Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Clas Rydergren; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; map matching; trajectory pattern mining; closed contiguous sequential pattern mining; trajectory pattern visualization; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Abstract : A large proportion of movement in urban area is constrained to a road network such as pedestrian, bicycle and vehicle. That movement information is commonly collected by Global Positioning System (GPS) sensor, which has generated large collections of trajectories. READ MORE

7. 5. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

   Author : Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. READ MORE
