   Författare :Can Yang; Yifang Ban; Gyözö Gidofalvi; Xiaoliang Ma; Mirco Nanni; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Parallel and Distributed Processing in the Context of Fog Computing: High Throughput Pattern Matching and Distributed Monitoring

   Författare :Charalampos Stylianopoulos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource-constrained devices; distributed monitoring; distributed processing; vectorization; pattern matching; high throughput; fog computing;

   Sammanfattning : With the introduction of the Internet of Things (IoT), physical objects now have cyber counterparts that create and communicate data. Extracting valuable information from that data requires timely and accurate processing, which calls for more efficient, distributed approaches. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

5. 4. Essays on Transport Economics

   Författare :Mattias Haraldsson; Per Johansson; Mogens Fosgerau; Uppsala universitet; []
   Nyckelord :Economics; Transport economics; marginal cost; distance work; matching; duration analysis; Nationalekonomi;

   Sammanfattning : Essay 1: The wear and tear of an extra vehicle that uses a road results in advancementof future repavements. This increases the present value cost of these repavements, which is interpreted as the marginal cost. LÄS MER

7. 5. Improving fingerprint biometrics by local symmetry and fusion

   Författare :Hartwig Fronthaler; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alignment; Matching; Minutiae Extraction; Image Restoration; Multi-expert Fusion; Biometrics; Symmetry Features; Structure Tensor; Quality Assessment; Fingerprint Recognition; Image Pyramid; Enhancement; Rotational Symmetry; Cascaded Fusion; Monomodal Fusion; Fingerprint;

   Sammanfattning : Fingerprint recognition and biometrics in general have been significantly gaining attention within the last years, not least due to the biometric passport that has been introduced all over Europe and the American immigration management system US-VISIT. The tasks of fingerprint recognition can be broken down to smaller entities, i.e. LÄS MER
