1. 1. 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

3. 2. Organization of information pathways in complex networks

   Författare :Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

   Sammanfattning : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level. LÄS MER

4. 3. Reconfigurable-Hardware Accelerated Stream Aggregation

   Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream; Reconfigurable Computing; Aggregation; Dataflow; FPGA; Memory Hierarchy; Compression;

   Sammanfattning : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. LÄS MER

5. 4. Streaming Aggregation using Reconfigurable Hardware

   Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Streaming; Aggregation; Dataflow; FPGA;

   Sammanfattning : High throughput and low latency streaming aggregation is essential for many applications that analyze massive volumes of data in real-time. In many cases, high speed stream aggregation can be achieved incrementally by computing partial results for multiple windows. LÄS MER

7. 5. Indivisible Wholes & Fragmented Realities : On the Aggregation of Disaster Risk Information

   Författare :Peter Månsson; Avdelningen för Riskhantering och Samhällssäkerhet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Societal Safety; Disaster risk management DRM ; Risk Governance; Multi-stakeholder; Risk and vulnerability assessment RVA ; Information management; Aggregation; Holistic; Societal Safety; Disaster risk management DRM ; Risk Governance; Multi-stakeholder; Risk and vulnerability assessment RVA ; Information management; Aggregation; Holistic;

   Sammanfattning : Division of labor and trade have been prerequisites for the development of welfare societies. Ironically, this specialization has caused a fragmentation of the knowledge necessary to understand risks that may undermine societal safety. LÄS MER
