3. 2. Machine learning for anomaly detection in edge clouds

   Författare :Javad Forough; Erik Elmroth; Monowar H. Bhuyan; Shahid Raza; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Edge Clouds; Anomaly Detection; Machine Learning;

   Sammanfattning : Edge clouds have emerged as an essential architecture, revolutionizing data processing and analysis by bringing computational capabilities closer to data sources and end-users at the edge of the network. Anomaly detection is crucial in these settings to maintain the reliability and security of edge-based systems and applications despite limited computational resources. LÄS MER

4. 3. A Theoretical Study: The Connection between Stability of Single-Walled Carbon Nanotubes and Observed Products

   Författare :Daniel Hedman; Andreas Larsson; Sven Öberg; Krisztián Kordás; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-walled carbon nanotubes; density functional theory; catalytic chemical vapor deposition; chirality-specific growth; stability; length; diameter; edge; chirality; Applied Physics; Tillämpad fysik;

   Sammanfattning : Over the past 20 years’ researchers have tried to utilize the remarkable properties of single-walled carbon nanotubes (SWCNTs) to create new high-tech materials and devices, such as strong light-weight composites, efficient electrical wires and super-fast transistors. But the mass production of these materials and devices are still hampered by the poor uniformity of the produced SWCNTs. LÄS MER

5. 4. Latency-aware Resource Management at the Edge

   Författare :Klervie Toczé; Simin Nadjm-Tehrani; Johan Eker; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The increasing diversity of connected devices leads to new application domains being envisioned. Some of these need ultra low latency or have privacy requirements that cannot be satisfied by the current cloud. By bringing resources closer to the end user, the recent edge computing paradigm aims to enable such applications. LÄS MER
