   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. 2. Complex patterns : from physical to social interactions

   Författare :Andreas Grönlund; Petter Minnhagen; Hawoong Jeong; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex networks; collective dynamics; statistical physics; random graphs; Statistical physics; Statistisk fysik;

   Sammanfattning : Interactions are what gives us the knowledge of the world around us. Interactions on all levels may fundamentally be seen as an exchange of information and a possible response of the same. Whether it is an electron in an electrical field or a handsome dude in a bar responding to a flirtation---interactions make things happen. LÄS MER

4. 3. Urban Growth Modeling Based on Land-use Changes and Road Network Expansion

   Sammanfattning : A city is considered as a complex system. It consists of numerous interactivesub-systems and is affected by diverse factors including governmental landpolicies, population growth, transportation infrastructure, and market behavior. LÄS MER

5. 4. Criminal Organizing : Studies in the sociology of organized crime

   Författare :Amir Rostami; Fredrik Liljeros; Christofer Edling; Petter Gottschalk; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organized crime; Criminal organizing; Social order; Mafia; Gang; Network; Sociology; sociologi;

   Sammanfattning : What organized crime is and how it can be prevented are two of the key questions in both organized crime research and criminal policy. However, despite many attempts, organized crime research, the criminal justice system and criminal policy have failed to provide a shared and recognized conceptual definition of organized crime, which has opened the door to political interpretations.

7. 5. Living Structure for Understanding Human Activity Patterns Using Multi-Source Geospatial Big Data

   Författare :Zheng Ren; Bin Jiang; Stefan Seipel; Itzhak Benenson; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; living structure; topological representation; human activities; natural cities; urban centres; complex network; head tail breaks; big data; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Geographic space is not neutral or lifeless, but an intricate living structure composed of numerous small features and a few large ones across all scales. The living structure is crucial for comprehending how geographic space shapes human activities. LÄS MER
