1. 26. Secure and Privacy-Preserving Cloud-Assisted Computing

   Författare :Georgia Tsaloli; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; differential privacy; decentralization; verifiability; privacy-preservation; secure aggregation; secret sharing; cloud computing; privacy;

   Sammanfattning : Smart devices such as smartphones, wearables, and smart appliances collect significant amounts of data and transmit them over the network forming the Internet of Things (IoT). Many applications in our daily lives (e.g., health, smart grid, traffic monitoring) involve IoT devices that often have low computational capabilities. LÄS MER

   Författare :Qinghua Wang; Tingting Zhang; Stefan Pettersson; Youzhi Xu; Yan Zhang; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor network; traffic analysis; network optimization; anomaly detection; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : Wireless sensor network (WSN) has emerged as a promising technology thanks to the recent advances in electronics, networking, and information processing. A wide range of WSN applications have been proposed such as habitat monitoring, environmental observations and forecasting systems, health monitoring, etc. LÄS MER

4. 28. Topological and Scaling Analysis of Geospatial Big Data

   Författare :Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. LÄS MER

5. 29. Dealing with Network Partitions and Mergers in Structured Overlay Networks

   Författare :Tallat Mahmood Shafaat; Seif Haridi; Ali Ghodsi; Anwitaman Datta; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structured Overlay Networks; Distributed Hash Tables; DHTs; Network Partitions; Network Mergers; Network Size Estimation; Lookup Inconsistencies; Gossiping; Computer science; Datalogi;

   Sammanfattning : Structured overlay networks form a major classof peer-to-peer systems, which are touted for their abilitiesto scale, tolerate failures, and self-manage. Any long livedInternet-scale distributed system is destined to facenetwork partitions. LÄS MER

7. 30. Understanding Human Mobility with Emerging Data Sources: Validation, spatiotemporal patterns, and transport modal disparity

   Författare :Yuan Liao; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel mode; data mining; travel time; mobility; social media data; gravity model; Twitter; geographical information systems;

   Sammanfattning : Human mobility refers to the geographic displacement of human beings, seen as individuals or groups, in space and time. The understanding of mobility has broad relevance, e.g., how fast epidemics spread globally. LÄS MER
